In 1906, Clemons von Pirquet correctly predicted that immunity and hypersensitivity reactions would depend on the interaction between a foreign substance and the immune system, and that immunity and hypersensitivity would have similar underlying immunologic mechanisms (1). The search for the factor responsible for immediate hypersensitivity reactions became a subject of intense investigation over several years. In 1921, Prausnitz and Kstner (2) described the transfer of immediate hypersensitivity (to fish protein) by serum to the skin of a normal individual. This test for the serum factor responsible for immediate hypersensitivity reactions was termed the Prausnitz-Kstner test. Variations of this test remained the standard for measuring skin sensitizing antibody over the next 50 years. In 1925, Coca and Grove (3) extensively studied the skin-sensitizing factor from sera of patients with ragweed hay fever. They called skin-sensitizing antibody atopic reagin because of its association with hereditary conditions and because of their uncertainty as to the nature of the antibody involved. Thereafter, this factor was called atopic reagin, reaginic antibody, or skin-sensitizing antibody. This antibody clearly had unusual properties and could not be measured readily by standard immunologic methods. Major research efforts from the 1920s through the 1960s defined its physical and chemical properties and measured its presence in allergic individuals (4,5). In 1967, the Ishizakas (6) discovered that skin-sensitizing antibody belonged to a unique class of immunoglobulin, which they called immunoglobulin E (IgE). In elegant studies using immunologic techniques, they clearly demonstrated that reagin-rich serum fractions from a patient with ragweed hay fever belonged to a unique class of immunoglobulin (6). In 1969, cooperative studies between these workers and Ishizakas confirmed that the proteins were identical and that a new class of immunoglobulin, IgE, had been discovered ( 7). IgE is a glycoprotein that has a molecular weight of 190,000 with a sedimentation coefficient of 8S. Like all immunoglobulins, IgE has a four-chain structure with two light chains and two heavy chains. The heavy chains contain five domains (one variable and four constant regions) that carry unique, antigenic specificities termed the epsilon (e) determinants (Fig. These unique antigenic structures determine the class specificity of this protein. Digestion with papain yields the Fc fragment, which contains the epsilon antigenic determinants, and two Fab fragments. B: The structure and characteristics of the surface receptors for immunoglobulin Fc regions. Cross-linking of high-affinity receptor-bound IgE by allergen results in the release of mediators from mast cells and basophils. The high-affinity receptor for IgE is composed of an a chain, a b chain, and two g chains, and it is the a chain that binds IgE ( Fig. The crystal structure of the a chain has been determined giving insights into the interaction of IgE with its receptor at the molecular level ( 12). The b and g chains are involved in signal transduction when the receptors are aggregated by the cross-linking of IgE, resulting in mediator release ( 13). Binding of IgE to this receptor places IgE at the center of activation of many important effector cells ( 16). It was found that lymphoid tissue of the tonsils, adenoids, and the bronchial and peritoneal areas contained IgE-forming plasma cells. IgE-forming plasma cells also were found in the respiratory and intestinal mucosa ( 17). However, unlike IgA, IgE is not associated with a secretory piece, although IgE is found in respiratory and intestinal secretions. The traffic of IgE molecules from areas of production to the tissues and the circulation has not been established. Areas of production in the respiratory and intestinal mucosa are associated with the presence of tissue mast cells (18). With the development of techniques to measure total IgE in the blood and the availability of purified IgE protein, investigators were able to study the metabolic properties of this immunoglobulin in normal individuals ( 19). It had been known for several years that the half-life of reaginic antibody in human skin as determined by passive transfer studies was about 14 days. This was reconfirmed with studies that investigated the disappearance of radiolabeled IgE in human skin. The basophil and mast cell-bound IgE pool needs to be investigated thoroughly, but it has been estimated that only 1% of the total IgE is cell bound. Tada (21) studied the production of IgE antibody in rats and found that IgE antibody production is regulated by cooperation between T lymphocytes (T cells) and B lymphocytes (B cells). The T cells provide the helper function, and the B cells are the producers of IgE antibody. In human systems, it became clear that IgE production from B cells required T-cell signals that were unique to the IgE system ( 22). This leads to T-cell B-cell interaction, mutual exchange of cytokine and cell contact signals, and enhanced allergen-specific IgE production. They found that cord serum contained 13 to 202 ng/mL and that the concentration of IgE in the cord serum did not correlate with the serum IgE concentration of the mother, which confirmed that IgE does not cross the placenta. In children, IgE levels increase steadily and peak between 10 and 15 years of age. Johansson and Foucard illustrate well the selection of population groups for determining the normal level of serum IgE. Studies of healthy Swedish and Ethiopian children showed a marked difference in mean IgE levels: Swedish children had a mean of 160 ng/mL, and Ethiopian children had a mean of 860 ng/mL ( 30).

They conclude that there need be no single determinate solution; they also conclude that symbolism matters that the same material transaction can take on very different meanings for different groups generic 400mg asacol fast delivery. Thus they describe hypothetical scenarios where organ selling might be permitted but with safeguards and concessions (with the aim of meeting some of the specific concerns of those intuitively opposed to a payment model) buy cheap asacol 400mg on line, or where such markets were banned best asacol 400mg, but financial incentives permitted in the form of honorary 503 awards for community spirit or as compensation for sacrifice order 400 mg asacol visa. The aim, in approaching evidence in these ways, is not to persuade people to accept one position or another, but rather to consider all sides of an argument to avoid cultural polarisation. In particular we note that one goal on the way to reaching a decision may be to find areas of overlapping consensus, even though particular policies may be supported by diverse audiences for diverse reasons. Oriented to a complex situation in which a diversity of facts, procedures, values and opinions is evident, the paper combines Fiskes (1991) relational theory and Tetlocks (1986) value pluralism model. Four elementary models "give motivational and normative force to social relationships" (1997: 258). These work as four procedures or ways of weighing up arguments, positions, or circumstances. We cite their example as a model of decision-making, not as a guide to our own arguments (it is not chosen to reflect the Working Partys view). While some of the claims made about altruism may be overblown, the notion of altruism as underpinning important communal values expresses something very significant about the kind of society in which we wish to live. A move away from a primarily altruistic model for research purposes may therefore pose a lesser challenge to solidarity and common values than such a move in connection with donation for treatment. This is true both of trust in individual professionals, for example that they will exercise a duty of care towards donors and respect their confidentiality; and of trust in systems, that they are the subject of good and responsible governance. The question needs to be asked before we examine the legitimacy of any particular effort to increase supply of bodily materials, or to reduce demand for them. In some 132 H u m a n b o d i e s : d o n a t i o n f o r m e d i c i n e a n d r e s e a r c h circumstances blood transfusion or organ transplantation may save or extend lives; in others they may significantly enhance quality of life. In the case of organs for transplant, we accept that on a patient-by-patient basis there is at present a chronic shortfall in terms of patient needs and expectations. Blood supplies are more stable but shortages do still intermittently arise, particularly for the less common blood groups (see paragraph 3. This creates a strong case for aiming to institute a range of public health measures that will reduce the chance that people will need blood or organs from others. At the same time, even if effective public health measures reduce the need for donation for some, medical services are still likely to be presented with many individuals who require donated organs and donated blood to maintain their ongoing basic health. Policy-makers must, of course, set these policies within a broader context of health policy more generally, and they will be aware of trade-offs and resource constraints within health budgets as a whole. To use a stark example, it may be that regulations requiring motorcycle riders to wear crash-helmets result in reductions in the availability of organs for donation. However, this clearly would not constitute any sort of justification for reversing the law on wearing crash-helmets: lives lost on the roads are just as significant, from an ethical perspective, as lives lost to shortage of organs. While tissue use is much less well-known, it too may serve to save life (for example through skin grafts) or significantly to enhance quality of life (for example through corneal transplants restoring sight). By contrast, access to tissue for research purposes (which again may in the long-term help save, extend or enhance quality of life but where such possible results are both remote and often unrealised) is often problematic, though at times for reasons of access rather than because of actual shortages of the material itself. These considerations suggest that we should not expect responses to supply and demand issues to be uniform across all areas and purposes of donation, either in terms of the urgency with which they should be tackled, or the means used to do so. Where the donation of gametes and embryos results in the birth of a child, this is both life-creating and (for the parents) life- enhancing. Others find gamete donation hard to rank in such a scale, 505 precisely because gametes are perceived as belonging in a quite different category. The 505 Opinion Leader (2010) Nuffield Council on Bioethics: human bodies in medicine and research - report of deliberative workshop on ethical issues raised by the donation of bodily material (London: Opinion Leader), p26; Hudson N, Culley L, 133 H u m a n b o d i e s : d o n a t i o n f o r m e d i c i n e a n d r e s e a r c h argument is also sometimes put that the numbers of vulnerable children in need of fostering or adoption should serve as a reason for not prioritising fertility treatment (with or without donated 506 gametes) at all. We are unconvinced that the pressing social need to provide secure families for children who are already in existence should be set against the desires of women or couples to bear a child of their own: we see no direct conflict between the two areas of social policy, and see no reason why support of the latter should be regarded as detrimental to the former. In short, we take the view that there is an ethical justification for taking steps to promote gamete donation. However, we note here that the very nature of gametes, that they may give rise to another person whose well-being is a matter of both private and public concern, means that this additional consideration has to be taken into account whenever donation in this context is contemplated. Such a consideration does not, of course, apply to the use of gametes for research purposes (whether research related to fertility or other health-related research), where no future child will ever result. The latter uses could again be compared to the use of tissue for research: the future benefit is uncertain but potentially highly valuable to health. In relation to first-in-human trials, it could be claimed that scarcity has been averted by allowing payments (sometimes substantial ones) to research participants, albeit such payments are formally couched in terms of compensation for time and inconvenience, rather than as inducements to participate. In recent years payment-in-kind schemes have been developed for gametes, and the courts have taken a relatively relaxed approach to the reimbursement of expenses to surrogate mothers (see paragraph 2. In the face of persisting shortages, some ethics commentators have suggested the establishment of a regulated market 508 in organs, and others have urged the Government to rethink the basis for authorising removal 509 of organs from a dead body. In what follows, we pay considerable attention to the justification for this stance. This does not, of Rapport F, Johnson M, and Bharadwaj A (2009) "Public" perceptions of gamete donation: a research review Public Understanding of Science 18: 61-77. Second, since some ways of meeting demand for bodily material may give rise to ethical concerns, a given jurisdiction is not obliged to meet all demands, even if other less scrupulous jurisdictions may be willing to do so. Third, there is room for reasonable pluralism among jurisdictions regarding the acceptability of particular interventions to increase supply or reduce demand. This by itself may have the result that countries with more plentiful supplies of material may meet the demand of countries with lower levels of supply. In spite of all this, regulators must be aware of the ways in which a failure to introduce practicable and ethically justifiable measures for reducing demand and increasing supply can contribute to exploitative, fraudulent and harmful treatment of vulnerable individuals in countries where illegal or poorly regulated systems for obtaining bodily material become established. The adoption of (national and international) protocols intended to protect the welfare of donors may be only a first step in ensuring that proper ethical appraisal takes place in any particular case. This is not just because implementation may be an issue; it is also because formal safeguards can only ever be part of the picture. Difficulties in ensuring appropriate ethical appraisal on the ground may particularly arise where health and after-care provision in general is uncertain. However, it is just as important (though sometimes politically more delicate) to acknowledge the possibility of addressing scarcity through managing demand. It is striking that public attitudes to markets in health care appear to differ significantly, depending on the care under consideration. Fertility treatment appears to be regarded by many in a light that allows it to leave the nationally- funded health service without too much public complaint. Indeed it is interesting that to some extent the growth of cross-border reproductive care has proved less controversial than attempts by specialists in the field of fertility treatment to drive down demand by educating women 513 regarding their fertility, and encouraging attempts to become pregnant earlier. And there are harder elements of policy, which might conceivably deny material to those who are thought to be particularly reckless with their health. Here the Council pointed out that public health schemes, if they are to be effective, cannot be based on individual consent, because by definition they affect large sections of society. Moreover, in its report, the Council took seriously the view that it is the role of states to limit health inequalities.

The exception was Peptic ulcer, where the new concept 1 Bibliography of Research Findings on Gastrointestinal Diseases in Myanmar regarding etiology (Helicobacter pylori infection) gave the stimulus and theme for a series of in-depth studies. Epidemiological methods were at first elementary and descriptive but soon progressed to analytical epidemiological methods to find causal relationships, like between intestinal helminthiasis and nutrition, diarrhoea and climate. Epidemiological modeling methods were used to predict and confirm the results of public health interventions such as mass chemotherapy on intestinal helminthiasis. Special techniques were used to investigate the action of microbial toxins - such as invasiveness, adherence and intestinal secretory response. Novel methods were introduced to investigate food iron absorption:- such as radioactive labeling of rice grown by hydroponic culture, double radio-labeled iron tracers to measure rice iron absorption and quantification of intestinal mucosal iron content. Radio-active tracers were used to investigate biochemical activity in intestinal mucosal cells such as effect of cholera toxin on amino-acid uptake by the gut. Anatomical methods - for study of gross and microscopic gut structure for academic purposes were those routinely available in college anatomy departments. Pathological methods ranged from routine histological methods to hitherto unused approaches like dissecting microscopy of intestinal villi obtained by Crosby intestinal capsule; and special histological stains to detect and measure intestinal mucosal cell contents like lactase enzyme. Aung Than Batu 3 Bibliography of Research Findings on Gastrointestinal Diseases in Myanmar 4 Bibliography of Research Findings on Gastrointestinal Diseases in Myanmar Introduction This bibliography was compiled with the aim to accumulate all available data on diseases and disorders of gastrointestinal tract research studies carried out in Myanmar. An extensive literature review was carried out to collect all published data on diseases and disorders of gastrointestinal tract research in country. In collection, literature written in English with research findings on human gastrointestinal diseases, and conducted by a research team which included at least one Myanmar investigator was compiled. Abstracts published in international and local conference/ seminars/ symposium/ were also compiled. All publications on diseases and disorders of the gastrointestinal tract recorded by biographies as mentioned in Who s Who in Medicine in Burma (1972) and Who s Who in Health and Medicine in Myanmar (2003) were included. The search was further extended to all medical subjects and to related science theses such as Zoology. Contact with libraries at Medical Universities, Arts and Sciences Universities, Myanmar Medical Association were made through visits, postal and email services. The information obtained were recorded and analyzed by place of research work, category of research, and type of information provided. The compiled abstracts are arranged according to the year of publication and are arranged according to the name of the first authors. The abstracts are numbered consecutively and continuously from 001 to 537 throughout all decades. Also, there is an Overview and Summing up at the end of each decade describing the nature of studies and the progress of scientific methods during that decade. An Expert Technical Committee for the Study of Intestinal Helminthic Infection in Burma was appointed by the Burma Medical Research Council in 1968. Although there have been several previous prevalence studies of intestinal helminths in Myanmar this Technical Committee conducted the first systemic attempt to review the situation and assess the health impact of intestinal helminthiasis in Myanmar. Its Report provided the framework and guidance for further research on the subject for many years to come. Descriptive epidemiological studies of intestinal helminthiasis were carried out in different urban and rural communities especially among school children. These studies and many more in the following decades provided base-line data on the extent of intestinal helminthiasis in the country. Cholera in epidemic form had been the main concern of the health administration and the people since colonial times. Now, the importance of acute (non-cholera) diarrhoea as a cause of high mortality and morbidity, especially in children, became better recognized and the subject of epidemiological and bacteriological studies. Bacteriological investigations of the responsible etiological agents for diarrhoea in children and cholera were done, using simple routine laboratory methods including serology. Anatomical studies of the stomach and gut were started in human cadavers beginning with description of variation in vascular supply. Physiological studies were begun on apparently healthy subjects - gastric acid secretion was measured using routinely available laboratory method. Clinical trials were undertaken - uncontrolled study of reputed traditional herb (Let-htoke-kyi) on acute amoebiasis and comparative study of two antihelminthic drug on helminthiasis. Surgical studies were undertaken clinical survey of gastro- duodenal hemorrhage in the large teaching hospitals. The types of studies undertaken were descriptive, except for the large analytical epidemiological investigation of diarrhoea. Some were by students from the few post-graduates courses which had started at Institutes of Medicine. Existence of cholera has been demonstrated in Burma in 1783 and in Irrawaddy Division during second pandemic in 1842. There was cholera every year in Burma and every year Irrawaddy Division was affected. In those days cholera was caused by "classical" cholera vibrios till 1963 a new strain, El Tor vibrio was imported. All ages are susceptible and teh highest incidence is observed in adults (age-groups 21-50 years). Males are affected more than females and urban areas are affected more than rural and the fatality higher in rural than urban. Cholera usually starts at the begining of summer in March and reached epidemic proportion in April and May with peak in May, and subsides when the rain fall in June. Course undertook an epidemiological investigation of parasitoses in Dayebo Village, Hlagu Township. A representative sample of 130 households (50 percent of the population) composed of 645 individuals were investigated. These were preserved in well marked containers containing 5ml of 5 percent formal- saline preservative. Of the total specimens the prevalence rates for specific helminthic infections were: 69 percent for strongyloidiasis. It should be borne in mind that these estimates are minimum estimates as they are based on a single preserved stool specimen. Had more specimens been taken, some of the negatives would have been found positive. Age, sex, family size and patterns of these infections were analyzed and discussed. Age and sex patterns for egg counts and worm loads for asariasis and trichuriasis (the commonest helminthic infections) are reported.

Only recently have data generated from volumetric sampling been widely based and a U cheap asacol 400 mg free shipping. Clearly buy asacol 400 mg with mastercard, the allergist arriving in an unfamiliar area needs to obtain or generic 400mg asacol mastercard, more often purchase asacol 400mg line, generate the information on which he or she will rely. Many difficulties attend the interpretation of traditional data and of compilations such as this chapter. In addition, some conventional wisdom reflects observations of source plants and land use rather than aerometric data. However, even the best available analysis can tell us only the genus or affinity group of origin for many pollens (e. Where allergen extract suppliers provide information, an obvious conflict of interest potential, favoring overly numerous important candidates for testing and treatment, must be resisted. This variety provides inherent challenge for the allergist, especially so because plant growth and land use rarely conform to political boundaries. Even divisions by state groupings, as attempted here, must be qualified for marked regional differences (e. Although published pollen data are often treated as revealed truth, there is little to justify such optimism. Local plantings of crops such as sugar beets, pecans, or dates may affect circumscribed populations within a perimeter. Because bioaerosols smaller than intact grains may carry pollen allergens, their potential for more extended travel without detection is obvious. Land use practices may modify pollen exposure patterns indirectly as well as by directly providing source species. Midwestern ragweeds, for example, selectively colonize cultivated fields and the margins of winter salted roads and are overgrown rapidly when such disturbance is removed. Changes in pollen prevalence over several decades also are referable to effects as diverse as street tree planting, reforestation (planned or as natural succession), and range extension by opportunistic species (e. The last of these effects deserves special attention in a setting of climate change as well as mounting travel and commerce between continents. Despite the aforementioned reservations, this chapter attempts to list clinically significant pollens on a state-by-state basis with their botanical names and approximate periods of peak prevalence. Where reference to two or more species of a single genus is intended, the abbreviation spp. Relative importance is implied by a three-level scale:+++, generally quite important; ++, of secondary importance; +, occasionally or locally worth considering. Pollen sources for each state or group are listed in the following order: trees, grasses, weeds (i.

Consequently when a patient has been troubled enough with one of these conditions to consult a physician, it is necessary to perform a complete medical evaluation. First, it must be determined if the symptoms are allergic in origin or if they have another cause. If the symptoms are considered to be allergic in origin, a more specific diagnostic evaluation must be completed by identifying the antigen or antigens responsible for producing the symptoms. The degree of sensitivity to an antigen may vary, as may the degree of exposure to a clinically significant antigen. Many patients are sensitive to multiple antigens, and cumulative effects of exposure to several antigens may be important. Considering the large number of variables, it is not surprising that the most important portion of any clinical evaluation is the expertly taken history. These may be useful, but they can only facilitate and not replace the careful inquiries of a skilled historian. The significant information can be obtained in some cases with relative ease, but adequate information usually can be obtained only after considerable time and energy has been invested. The history not only provides most of the information necessary for diagnosis, but it is necessary before further diagnostic tests can be selected that will help confirm the diagnosis and not be dangerous to a patient with an extreme degree of sensitivity. The patient is asked to state his or her major complaint and to describe the symptoms. During the history, the presence or absence of symptoms of nonallergic conditions must be determined and evaluated. Certain details of the allergic history are so characteristic that they should be always be specifically asked and noted: 1. Are there other symptoms in addition to the presenting complaint that may be allergic in origin? Several allergic symptoms frequently exist simultaneously even though the patient has not associated them with a common cause. If several of these symptoms are present, it is more likely that they all have an allergic origin. Conversely, a single symptom in a single system such as isolated nasal obstruction probably is not allergic. A good response to antihistamines would increase the likelihood that the symptoms have an allergic origin. A prior good response to immunotherapy would strongly implicate an allergic problem. Allergic symptoms are often intermittent, and even in those cases in which they are continuous, there may be intermittent exacerbations. A careful history can often narrow the list of suspected allergens responsible for the symptoms of allergic diseases. This facilitates selection of further diagnostic tests and minimizes the amount of testing performed. Awareness of these reactions can prevent unnecessary and expensive allergic evaluations. Some general characteristics of the antigens responsible for allergic illnesses must be appreciated before an adequate clinical history can be obtained or interpreted. Symptoms characteristically produced by common antigens Pollens The grains of pollen from plants are among the most important antigens that cause clinical sensitization.

Importing bodily material from abroad (potentially any form of bodily material) 3 discount asacol 400 mg online.

It is foreseen that the proposal for a revision of the Directive will be adopted in 2012. Some recent major campaigns in relation to blood and organs gametes are summarised in Box 3. As they progress, the camera focuses on one man, and the caption "severed artery, Monday 11:40am" appears. At the end of each advertisement, a voiceover asks viewers to "give blood, and you can save someones life. These include Adrian Turner, a former Olympic swimmer who had to have his spleen removed as a teenager and needed a blood transfusion. The website also focuses on those who still need blood, such as James Baffoe, a young man with sickle cell anaemia. In a video interview, he notes that "if I dont receive red cell exchanges, I would have a lot more crises; a lot more stays in hospitals, and I hate hospitals. The campaign uses several Welsh celebrities, including Colin Jackson and James Hook. For example, while disease-specific charities or research organisations may run campaigns for 443 certain types of bodily tissue to be donated for research, there are no overarching national campaigns to encourage patients to give unneeded tissue remaining after medical procedures for research purposes. Recognising the costs of donation (all forms of material and first-in-human trials) and non- financial tokens of gratitude (blood and organs) 3. Explicit payment for participation in first- in-human trials is, by contrast, routine (see paragraph 2. Examples of non-financial tokens of gratitude include inclusion in public memorials such as the service of thanks for people who have donated their body to medical research, held each year at Southwark Cathedral. These approaches may include 450 national memorials, local initiatives and personal follow-up to donor families. They could also include a system for the sale and purchase of organs or gametes, whether at non-market rates via a governmental organisation or in a fully-fledged free market. Israel has recently introduced such a scheme in respect of organ donation: citizens who commit to donating their own organs after death are promised priority in the queue 452 for an organ transplant, should they ever need one (see paragraph 2. However, because a reduced number of eggs is available to the egg sharer, she will have fewer frozen embryos, and therefore her cumulative pregnancy rate may be lower than if she had kept all the eggs for own use. There is some evidence to suggest that egg sharing is not an option 461 many women choose if other routes to pregnancy are available. Individuals may seek the help of an intermediary in such searches: for example a recently-established website offers to manage the recruitment of 471 egg donors for potential recipients. However, concerns have also been expressed that direct recruitment of donors in this way may potentially lead to the prohibition on financial reward for 473 donors being subverted in some cases. Initial conclusions suggest that significant drivers for people deciding to travel abroad for fertility treatment include a shortage of egg donors, the risk of long waiting times for treatment, and issues of cost. The process of cross-border fertility treatment may be prompted 478 by clinics, or taken wholly at the initiative of the individual. The preamble to the Declaration of Istanbul on Organ Trafficking and Transplant Tourism (Steering Committee of the Istanbul Summit), 2008, states, for example: "The legacy of transplantation must not be the impoverished victims of organ trafficking and transplant tourism 480 but rather a celebration of the gift of health by one individual to another". Recent media reports from Kosovo, India and South Africa appear to 482 confirm this. Ethical values often invoked in response to such concerns include: Altruism Autonomy Dignity Justice Maximising health and welfare Reciprocity Solidarity. This does not mean that they become redundant but rather that the way they are being used in particular circumstances needs to be made explicit and, where necessary, justified. It epitomises the opposite of theft and seizure by force, and in so doing it points to the desirability of material properly given rather than improperly taken. In donation, public and private are understood in many different ways, and it may be more helpful to think of public and private as being complementary and overlapping rather than as in opposition. We note how an awareness of these factors adds to the importance of seeking to find areas of mutual agreement and concern, where particular policies may be supported by diverse audiences for diverse reasons. These two aspects of the donation or volunteering of bodily material have generated a number of (sometimes competing) ethical concerns around consent, control, and ownership (See Box 4. Addressing the legitimate role of public and private bodies in responding to that shortage, the question becomes: how far should public and private bodies go in encouraging, or even incentivising, people to provide their bodily material or to volunteer for a trial? It will also consider the importance of considering the context in 485 which appeal is made to these values (see paragraph 4. The purpose of doing so is to highlight how controversies and disputes that arise in connection with the donation of bodily material are often not so much about the respective merits of particular values, but rather about the ethical dilemmas with which these values are associated, and the way in which values are invoked to make particular claims. Altruistic giving may be to strangers, or may take place within the context of family or other relationships. The widespread support for this model for donation is found both in the regulatory emphasis on voluntary and unpaid donation (see Box 2. Such descriptions contrast with the not infrequent portrayal of those paid to participate in first-in-human clinical trials as human guinea-pigs. Some argue, however, that a model of individual altruism no longer sits easily in the more commercial world of modern health care: why should those providing material be required to act on an altruistic basis when everyone else involved in the transaction is remunerated in some way? Others express concern that the traditional altruistic model can often be subject to hidden coercive pressures, as when patients on a transplant list might expect a suitable relative to donate an organ to help them. Values should therefore be prioritised relating first to the individual and then society. An example might be when an emerging new infection threatens to become a serious public health issue, in which case testing samples in an existing tissue bank without donor consent could be justified. Concerns about coercion and undue inducement undermining valid consent similarly reflect the importance attached to ensuring that decisions about a persons body are freely and autonomously made by the person concerned. More controversially, it may also be argued that respect for autonomy should entail permitting people to do what they wish with their own bodies, including selling their bodily material as a commercial transaction. Similarly, it may be thought desirable actively to encourage autonomy by making people responsible for their own circumstances, as in the move away from what comes to seem medical paternalism. Such concerns may be exacerbated if money enters the equation: in a Kantian view, dignity and price are essentially mutually incompatible. Putting a price on a human being, or on part of their body, may be seen as giving it a relative value, whereas human beings are of incomparable ethical worth. Others argue that there is nothing inherently undignified in providing bodily material in return for a fee and that degradation depends on ones own perception of what is degrading. Issues of justice arise in at least two distinct contexts in donation and volunteering. On the one hand, concerns arise that those who are most likely to donate or volunteer may be the least likely to benefit from access to the services of which the donation/volunteering is part. Those volunteering for first-in-human trials, for example, may be those who have poor access to health care and are 120 H u m a n b o d i e s : d o n a t i o n f o r m e d i c i n e a n d r e s e a r c h unlikely to access the resulting benefits. Similarly, a key anxiety about any form of commercial market for bodily material is that it may induce primarily the poorest and most vulnerable members of society into becoming donors, with the main recipients being the better-off. This could occur both within individual countries (low, middle and high income countries alike) and also lead to inhabitants of lower income countries becoming the main source of organs and gametes donor nations for the inhabitants of wealthier nations.
