Abstract
OBJECTIVES This article describes a method for developing electronic health record (EHR) tools for use in primary care settings. METHODS The "Translating Research into Agile Development" (TRIAD) method relies on the close collaboration of researchers, end users, and development teams. This five-step method for designing a tailored EHR tool includes (1) assessment, observation, and documentation; (2) structured engagement for collaboration and iterative data collection; (3) data distillation; (4) developmental feedback from clinical team members on high-priority EHR needs and input on design prototypes and EHR functionality; and (5) agile scrum sprint cycles for prototype development. RESULTS The TRIAD method was used to modify an existing EHR for behavioral health clinicians (BHCs) embedded with primary care teams, called the BH e-Suite. The structured engagement processes stimulated discussions on how best to automate BHC screening tools and provide goal tracking functionality over time. Data distillation procedures rendered technical documents, with information on workflow steps, tasks, and associated challenges. In the developmental feedback phase, BHCs gave input on screening assessments, scoring needs, and other functionality to inform prototype feature development. Six 2-week sprint cycles were conducted to address three domains of prototype development: assessment and documentation needs, information retrieval, and monitoring and tracking. The BH e-Suite tool resulted with eight new EHR features to accommodate BHCs' needs. CONCLUSION The TRIAD method can be used to develop EHR functionality to address the evolving needs of health professionals in primary care and other settings. The BH e-Suite was developed through TRIAD and was found to be acceptable, easy to use, and improved care delivery during pilot testing. The BH e-Suite was later adopted by OCHIN Inc., which provided the tool to its 640 community health centers. This suggests that the TRIAD method is a promising research and development approach.

Abstract
The Swedish health care system is reorienting towards horizontal organization for care processes. A main challenge is to engage health care clinicians in the process. The aim of this study was to assess engagement (i.e. attitudes and beliefs, the cognitive state and clinical engagement behaviour) among health care clinicians, and to investigate how engagement was related to work resources and demands during organizational redesign. A cohort study was conducted, using a questionnaire distributed to clinicians at five hospitals working with care process improvement approaches, two of them having implemented Lean production. The results show that kinds of engagement are interlinked and contribute to clinical engagement behaviour in quality of care and patient safety. Increased work resources have importance for engagements in organizational improvements, especially in top-down implementations. An extended work engagement model during organizational improvements in health care was supported. The model contributes to knowledge about how and when clinicians are mobilized to engage in organizational changes.

Abstract
The goal of improving patient safety has led to a number of paradigms for directing improvement efforts. The main paradigms to date have focused on reducing injuries, reducing errors, or improving evidence based practice. In this paper a human factors engineering paradigm is proposed that focuses on designing systems to improve the performance of healthcare professionals and to reduce hazards. Both goals are necessary, but neither is sufficient to improve safety. We suggest that the road to patient and employee safety runs through the healthcare professional who delivers care. To that end, several arguments are provided to show that designing healthcare delivery systems to support healthcare professional performance and hazard reduction should yield significant patient safety benefits. The concepts of human performance and hazard reduction are explained.

Abstract
Recent evidence suggests that the p53 molecule appears in two different forms: the mutant p53 that stimulates tumor progression, and wild type p53 that inhibits tumor progression. In addition, it has been established that tumor necrosis factor-alpha (TNF-alpha) can activate the expression of wild type p53 in concert with the nuclear transcription factor, NF-kappa B. Both TNF-alpha and NF-kappa B are also involved in the stimulation of the pathway that leads to the expression of major histocompatibility complex (MHC) class I molecules and, hence, antigen presentation to the T cells. In this paper we shall advance the hypothesis that: (i) TNF-alpha indirectly controls immune surveillance; and (ii) TNF-alpha controls DNA repair and tumor suppression through the regulation of wild type p53. Thus, it is hypothesized that elevated TNF-alpha is primarily responsible for promoting tumor progression.

Abstract
In this review, tumor necrosis factor-alpha (TNF-alpha) is identified as the uniting principle linking the pathogenesis of insulin-dependent diabetes mellitus (IDDM), non-insulin dependent diabetes mellitus (NIDDM) and carcinoma. Elevated TNF-alpha initially increases, and then inhibits, the activity of a number of key enzymes involved in energy metabolism and major histocompatibility (MHC) class I molecule expression. These enzymes include: protein-tyrosine kinase (PTKase) and protein-tyrosine phosphatase (PTPase--enzymes involved in energy metabolism, cell proliferation and stimulation of the MHC class I molecule pathway. Of primary importance is the inhibiting effect of TNF-alpha on PTKase, since this induces insulin resistance in NIDDM and carcinoma, and PTPase, which inhibits MHC class I molecule expression. Studies have shown that IDDM is associated with an increase in PTPase activity which leads to overexpression of MHC class I molecules and a concomitant destruction of pancreatic beta cells. Conversely, carcinoma is associated with an inhibition of PTPase activity, which reduces the expression of MHC class I antigen expression on the cell surface thereby allowing malignant cells to escape immune surveillance. It will be argued that there is continuum of liability between these three conditions, initiated by the effect of TNF-alpha on these key enzymes.

Abstract
The purpose of this review is to indicate the role insulin plays in normal brain neurophysiology, together with the role insulin may play in the regulation of regional cerebral blood flow (rCBF). The relationship between sustained elevation of the inflammatory cytokines and brain insulin dysregulation, with respect to the serious mental disorders, is also discussed. It has been observed that, as the inflammatory cytokines increase, they exert a synergistic influence on insulin and somatostatin, by initially increasing and then decreasing insulin secretion. In the brain, increased levels of insulin result in increased glucose utilization and over-stimulation of the autonomic nervous system (ANS), while the inhibition of insulin secretion results in decreased glucose utilization and dysregulation of the hypothalamo-pituitary-adrenal (HPA) axis. It will further be argued that these alterations in brain insulin influence rCBF in the serious mental disorders such as schizophrenia and the affective disorders. It is hypothesized that insulin regulates rCBF either directly, or indirectly via GLUT4 in the hypothalamus now considered the glucose-sensing, insulin-sensing mechanism of the brain and the body. Thus, we shall propose that insulin plays an important role in normal neurophysiology and that sustained elevation of the inflammatory cytokines dysregulates insulin secretion, rCBF, ANS and the HPA-axis in serious mental disorders.

Abstract
Since the time of Freud, psychiatry has embraced the proposition that physiological and/or psychological stress precipitates various psychiatric disorders. To this effect, we propose that a continuum of liability obtains between stress, anxiety states and anorexia nervosa--a continuum which is grounded on a cytokine profile common to each of these conditions. For example, the biological response to stress, anxiety states and anorexia nervosa includes the elevation of interleukin-1 beta (IL-1 beta) and tumor necrosis factor-alpha (TNF-alpha), and downregulation of interferon-gamma (IFN-gamma). Sustained elevation of IL-1 beta and TNF-alpha dysregulates both somatostatin and insulin secretion, the latter of which influences regional cerebral blood flow (rCBF) and brain energy metabolism. In addition, IL-1 beta and TNF-alpha influence the expression of certain crucial neuropeptides, which are known to be associated with anxiety states and anorexia nervosa. These neuropeptides include: beta-endorphin, cholecystokinin (CCK), neuropeptide Y (NPY) and vasoactive intestinal peptide (VIP). beta-endorphin effects glucose metabolism in the limbic system, CCK increases the release of beta-endorphin from the anterior pituitary, NPY is a powerful anxiolytic that regulates beta-endorphin and insulin, while VIP indirectly regulates the expression of TNF-alpha through the inhibition of interleukin-4 (IL-4).

Abstract
Recently there has been considerable conjecture in the literature concerning a possible relationship between stress, depression and bereavement, and carcinoma. We shall propose a causal model in which the relationship between stress, depression and carcinoma is clarified. This relationship is grounded on dysregulation of the inflammatory cytokines in stress and depression. Stress is associated with increased expression of interleukin-1 beta (IL-1 beta) and tumor necrosis factor-alpha (TNF-alpha), and reduced expression of IL-2, interferon-gamma (IFN-gamma), major histocompatability complex (MHC) class II molecules and natural killer cell activity (NKA). Depression is associated with elevated IFN-gamma and IL-1 beta, downregulated IL-2, and reduced NKA. Most organ-related carcinomas are associated with elevated TNF-alpha, which inhibits the activity of protein tyrosine phosphatase (PTPase), the enzyme that initiates activation of the MHC class I pathway. Sustained elevation of TNF-alpha inhibits the activity of PTPase which results in diminished expression of the MHC class I antigen on the cell surface and thus, malignant cells escape immune surveillance. Therefore, stress and depression can foster tumor progression by means of inhibiting the expression of MHC class I and II molecules and through the reduction of NKA.

Abstract
In this paper a new immunological model of anorexia and bulimia nervosa will be presented in which the inflammatory cytokines are conceived as the fundamental regulators of body metabolism. This conception differs from the conventional view in which the inflammatory cytokines are perceived primarily as peptide molecules utilized by the immune system to control infection, inflammation and tissue or neuronal damage. Given that the inflammatory cytokines are also fundamental regulators of body metabolism, when they become dysregulated they create physiological chaos which results in the development of a number of autoimmune, metabolic and psychiatric disorders. In this proposed immunological model of anorexia and bulimia nervosa, elevated tumor necrosis factor-alpha features as the primary cause of these conditions. Pathophysiological parallels are drawn between anorexia nervosa and cancer cachexia in terms of the causal role the cytokines, neuropeptides and neurotransmitters play in the manifestation of shared symptoms. These shared symptoms include elevated tumour necrosis factor-alpha, down-regulated interleukin-2 and interleukin-4 and depletion of lean body mass. Furthermore, the following neuropeptides are dysregulated in both anorexia nervosa and cancer cachexia: vasoactive intestinal peptide, cholecystokinin, corticotropin-releasing factor, neuropeptide Y, peptide YY and beta-endorphin. In addition, in anorexia and bulimia nervosa, secretion of the neurotransmitter serotonin is inhibited while norepinephrine is enhanced. It will be argued that the causal interplay between the cytokines, neuropeptides and neurotransmitters initiates a cascade of biochemical events which may result in either anorexia or bulimia nervosa, or cancer cachexia. The extent to which these inflammatory cytokines, neuropeptides and neurotransmitters are causally efficacious in the pathogenesis of other autoimmune disorders, such as diabetes mellitus and rheumatoid arthritis, will also be addressed.

Abstract
This paper aims to explore the influence of the immune system on the pathobiochemistry of movement disorders (Tourette syndrome, obsessive compulsive disorders and attention-deficit disorder, with and without hyperactivity) and schizophrenia. In children, a temporal relationship has been observed between contraction of a group A beta-hemolytic streptococcal infection and subsequent presentation with one of the movement disorders. Pathology investigations reveal that elevated antineuronal antibodies are associated with movement disorders. Similarly, elevations in interleukin-1 beta and interleukin-6 have been reported in schizophrenia. It is now known that the immune system can be activated by conditions other than a viral or bacterial infection, such as: neurological insult, neurotoxicity--endogenous and environmental, neurotransmitter and cholesterol dysregulation. These latter avenues of immune system activation will be explored with respect to schizophrenia.

Abstract
Alzheimer disease is characterized by the presence of beta-amyloid protein deposits, neurofibrillary tangles and cholinergic dysfunction throughout the hippocampal region. In addition, the hippocampus, hypothalamus and olfactory bulb--the three areas where the insulin receptors are most dense--are also subject to neurodegeneration. The exact cause of the beta-amyloid deposits and NFTs is unknown. However, it is our intention to explicate the various pathogenic pathways through which Alzheimer disease arises. Fundamentally, the structural and metabolic damage found in Alzheimer disease is due to sustained elevation of interleukin-1 beta, a feature which is also found in insulin-dependent diabetes mellitus. Similarly, the beta-AP deposits found in the Alzheimer brain share the same molecular structure as the amylin deposits found in the pancreatic beta-cells in non-insulin-dependent diabetes mellitus (NIDDM), and are equally neurotoxic. These, and other pathophysiological parallels, afford some insight into the probably cause of Alzheimer disease and, as such, forms the basis of the causal hypothesis advanced in this paper.

Abstract
For some considerable time, there has been a growing awareness that defective essential fatty acid metabolism plays a causal role in the pathogenesis of both schizophrenia and non-insulin-dependent diabetes mellitus (NIDDM) but the influence of defective essential fatty acid metabolism in the pathogenesis of rheumatoid arthritis and cancer is less well appreciated. An EFA deficiency, or defective EFA metabolism, negatively influences prostaglandin synthesis and glucose regulation and transport. Moreover, defective EFA metabolism negatively influences estrogen availability which contributes to the observed gender bias some of these illnesses manifest. While fluctuations of estrogen are known to contribute to the pathogenesis of these conditions, so also do fluctuations of IGF-II and there is some suggestion that IGF-II and insulin may well be inversely regulated. In addition, insulin-dependent diabetes mellitus (IDDM), rheumatoid arthritis, and schizophrenia are thought to be autoimmune disorders, while cancer is associated with immune system failure. Consequently, this paper aims to examine the pathophysiological similarities and differences between mental illness, diabetes, rheumatoid arthritis and cancer in respect of which the causal relationship that obtains between essential fatty acids, estrogen, IGF-II, glucose regulation and autoimmunity will be addressed.

Abstract
In this paper, the relationship between schizophrenia, suicide and serotonin will be examined. Throughout, it will be argued that the fundamental problem does not lie with the neurotransmitter per se, but rather with uncontrolled fluctuations of brain glycaemic levels acting in conjunction with insulin resistance. It will be shown that the area of dopaminergic and serotonergic activity in the brain is intimately tied to the relative distribution of the central glucose transporters and, hence, to glucose metabolism and insulin activity. It will be argued that mania and positive schizophrenia represent a continuum of liability associated with hyperglycaemia, hyperdopaminergia, and hyperserotonergia. In contrast, depression and negative schizophrenia represent another continuum of liability involving hypoglycaemia, hypodopaminergia, and hyposerotonergia. This serves as a useful distinction in drawing together a large number of seemingly unrelated, diverse facts concerning both schizophrenia and suicide and, in particular, the possible relationship that obtains between cholesterol-lowering drugs, low serotonin and suicide. Essentially, this paper reaffirms a previously stated contention that mental illness, in its many guises, is a general manifestation of a diabetic brain state which has been termed 'cerebral diabetes'.

Abstract
The article outlines the relationships that obtain among schizophrenia, smoking, and smog. An overview of known scientific facts concerning the pathogenesis of schizophrenia is first provided. The relationship this has with nicotine addiction is discussed next, and finally the notion is introduced that heterocyclic amines found in cigarette smoke and petroleum fumes serve as a potent environmental neurotoxin that seriously compromises mental health in biologically susceptible individuals. It is argued that such biologic susceptibility takes the form of cerebral diabetes, which accounts for the serious impairment of glucose metabolism as demonstrated by positron emission tomography. Central to this argument is the view that diabetes can be peripheral, without affecting the central nervous system, or central, without affecting the peripheral system.

Abstract
In this paper a detailed argument will be advanced in support of the notion that schizophrenia is fundamentally a diabetic brain state, henceforth referred to as 'cerebral diabetes'. Many extraneous features of cerebral diabetes have been observed, including positron emission tomography (PET) scans which reflect abnormal distribution patterns and diminished supplies of glucose in the brain. Equally, empirical research has demonstrated that plasma levels of essential fatty acids and prostaglandins are abnormally low, and low levels of glycoproteins in the urine of cerebral diabetics have also been observed. In addition, cerebral diabetics manifest a wide range of disturbing physical symptoms, such as, impaired sexual function, temperature control, low blood pressure, disrupted sleep patterns, excessive thirst, poor memory, insensitivity to pain, and chronic unhappiness, all of which can be attributed to disrupted neuroendocrine function. Thus, in order to persuasively assert the redefinition of schizophrenia as 'cerebral diabetes', we shall first explicate glucose regulation and transport in the brain and then outline how this interacts with essential fatty acids and prostaglandins, neurotransmission, and the neuroendocrine system. In so doing, we shall provide a metabolic explanation for all the prominent symptoms currently known to be associated with cerebral diabetes and indicate some future therapeutic interventions.

Abstract
Schizophrenia has become an elusive medical conundrum since it was first described at the turn of the 19th century. Over time, a variety of causal hypotheses have been advanced to explain the spectrum of schizophreniform disorders. This etiological explanation outlines the relationship that obtains between smoking, schizophrenia, and impaired glycometabolism which also includes disruption to the dopaminergic and serotinergic pathways. A possible genetic explanation for this disruption will be identified which links mental illness to a locus of genes contained on the short arm of chromosome 11. These genes are all essential to normal glucose transport which positron emission tomography (PET) scans show is seriously abnormal in schizophrenia. Thus, a redefinition of schizophrenia as 'cerebral diabetes' will be proposed since this term implies a diabetic brain state consistent with PET scans of schizophrenic patients.

Abstract
A prospective study of dyspepsia was carried out in a primary referral hospital between 1974-1987 including 1540 patients of whom 1433 were seen as outpatients. The study protocol was agreed in advance and a structured questionnaire was used to elicit relevant clinical information: up to three diagnoses were permitted for each patient. The commonest principal diagnoses were duodenal ulcer (26%), functional dyspepsia (22%), and irritable bowel syndrome (IBS) (15%); alcohol related dyspepsia (4%) was as common as gastric carcinoma or symptomatic gall stones. Multiple diagnoses were common (31% given two diagnoses, and 6% given three) so that in all 2111 diagnoses were given to 1540 patients; the functional disorders (IBS and functional dyspepsia) considered together accounted for 39% of all diagnoses made. Whereas organic conditions were diagnosed by clinicians with confidence (63-98% considered 'certain'), even when given as the principal or first diagnosis IBS was considered 'certain' in only 61% and functional dyspepsia 48%. The demographic symptom data, together with information on tobacco and alcohol use, and work lost are described in detail.

Abstract
Unipolar depression, alcoholism and suicide have become more common over the past decades. Genetic studies have attempted to link (bipolar) affective disorder to the short arm of chromosome 11 (where the loci for insulin, insulin growth factor (IGF), tyrosine hydroxylase (TH) and h-ras-oncogene are located) but these have failed. Since TH and the insulin receptor require phosphorylation by protein kinases, then a defect of the h-ras-oncogene or its products (p21) could disorder both these systems and compromise catecholaminergic transmission in neurones and energy flow in glial cells. This could lead not only to a predisposition to depression ('trait markers') but to neurotoxic damage, predisposed by inadequate cytosol Mg2+ levels of hypometabolism. Tyrosine, tryptophan and phenylalanine hydroxylases all require tetrahydrobiopterin (BH4) which allosterically regulates its own activity as well as that of these enzymes. Anything which impairs this cofactor could lead to overt depression in predisposed individuals, and the heterocyclic amines are being increasingly implicated. These substances are derived from fried and broiled meats, azo food dyes, soft drinks and hard candies, but particularly from cigarette and petroleum fumes. The heterocyclic amines can inhibit aromatic-l-amino-acid-decarboxylase (AADC) as well as the hydroxylases reversibly, but BH4 is inhibited noncompetitively. Thus, susceptible individuals (those with inherited defective protein kinase phosphorylation) might be 'tipped over' by chronic exposure to these neurotoxins. The rising incidence of unipolar depression-associated morbidity could be significantly linked to increasing levels of heterocyclic amines in the developed nations.

Abstract
A sizable proportion of nursing curricula subtly indoctrinate students with a particular normative ethic. Seldom is there adequate philosophical justification for the ethic, and students are rarely invited to subject that ethic to a rigorous philosophical analysis. Nursing curricula are replete with philosophical positions treated as moral imperatives to which all, students and faculty, owe their allegiance. This unsatisfactory situation warrants urgent attention. One problem is that of failing to justify the school's moral philosophy; another is the question of philosophically indoctrinating students to adhere to an ethic that advocates the individual's freedom and responsibility, a practice inconsistent with the predominant proposition advanced by the ethic.

Abstract
In this paper, the author proposes to consider the intricate interplay between the art and science of nursing. The caring role, intrinsic to the meaning of the word 'nurse' constrains nursing under the rubric of the arts, while nursing that embraces high technology constrains the discipline under the rubric of science. Thus, the traditional dichotomy that obtains between the arts and sciences seriously complicates the notion of nursing. As a science, nursing adopts the materialist theory of the mind that endorses the inseparability of mind and body. However, as an art, nursing is more closely aligned with dualist interactionism which considers the mind and body to be separate, interacting entities. Nursing is a caring profession, the mastery of which rests on the mastery of the therapeutic relationship which, in turn, implies mastery of holistic nursing care. While the concept of holism implies caring for the 'whole' person in body, mind and spirit, such acknowledgement of the mental and spiritual components of personhood, immediately invites the entry of dualism into our theoretical discourse. Thus, rejection of dualism consigns nursing to theoretical impoverishment and therapeutic emasculation. The contentious question is therefore: Is the theoretical destiny of nursing one of theoretical impoverishment, therapeutic emasculation, and permanent consignment to professional ignominy--and all for the sake of an inconvenient soul?

Abstract
1. Pressure from educational institutions on clinical facilities necessitates the creation of alternative strategies that enable students to develop clinical skills outside the artificial atmosphere of a nursing laboratory or the formal clinical setting. 2. Assignments covering grief and loss experienced by the elderly; problems in performing activities of daily living experienced by the non-elderly; and existential anxieties experienced by the elderly help students to realize that such problems are not confined to those residing in institutional settings. 3. Each of these assignments sensitizes students to the practical reality of a variety of theoretical frameworks, which provides students with the opportunity of applying theory to practice in a nonthreatening environment.

Abstract
This paper presents a study of the particular dynamics within hospitals that act as counterproductive forces to caring. To this end, the insights revealed by Isabel Menzies Lyth, following her observations of a large London teaching hospital, will be explored. She argues that hospitals are environments conducive to the erection of primitive social defence systems that generate internal conflict and persecution anxiety within its staff. These social defence systems, in turn, militate against efforts directed towards caring. This results in feelings of guilt, depression and dependency that rapidly establish a negative cycle of affects. Such negative affections, once set in train, are difficult to terminate and transform into a positive cycle of affections. Following this analysis, it will be argued that the hospital environment is unequal to the task of caring for the caregivers because it is permeated with ontological, spiritual and moral anxiety, all of which act as serious impediments to the caring enterprise.

Abstract
In this paper, the consequences were there greater autonomy in nursing practice, are considered. Autonomous practice implies accountability which entails both personal and professional responsibility: a personal responsibility to endorse ethical conduct consistent with professional practice; and a professional responsibility to exercise discretionary powers to the ultimate benefit of the patient. In this context, discretionary responsibility implies: recognizing a patient's wants may not be consistent with a patient's needs; abstaining from collusion with noncompliant patients; supporting the patient's right to refuse treatment only after full psychological exploration; understanding the psychological ramifications of informed consent from a practitioner and recipient point of view; maintaining appropriate personal and professional boundaries; and fostering collegiate relationships with the medical fraternity grounded on egalitarian principles. The author provides a philosophical and psychological analysis of responsibility in an effort to achieve a deeper understanding of the relationship this has with the concepts of 'freedom' and 'accountability'.

Abstract
In this paper I propose to examine the theoretical underpinnings of phenomenological research which is plagued with the same methodological problems that confronted psychoanalysis at the turn of the century. Some general criticisms levelled at both phenomenological and psychoanalytic research, by philosophers of science, point to: the absence of falsifiable hypotheses; the absence of measurable and observable data; and the absence of an explanatory general theory upon which the study of consciousness may be grounded. The primary task of the present analysis is to articulate the structural similarities that obtain between psychoanalysis and phenomenology in the expectation that the rules of evidence governing psychoanalytic research may also apply in the government of phenomenological research. Finally, I shall offer some procedural suggestions phenomenologists might care to consider.

Abstract
The current prevalent attitude of disapprobation towards the medical model, held by nurse practitioners and educationalists alike, stems from a desire to denounce diagnostic reductionism and proselytize holistic care. It is argued, that the medical model encourages the perception that the patient is "essentially and only their medical diagnosis," and to relate to patients 'as if' they are kidney, a broken leg, a gall stone, or an ulcer, is to dehumanize the person. In order to overcome this predilection, the patient must be seen as a 'whole person' and not simply as some extraneous part of their dysfunctional anatomy. But this all too pervasive tendency, to reduce patients to nothing more than their medical diagnosis, is surely not the responsibility of the medical model? On the contrary, it is the responsibility of the individual medical or nurse practitioner who, on formulating a medical diagnosis, proceeds to convert the patient into an object and from there on regards the patient as "essentially and only their diagnosis of illness."

Abstract
Primary biliary cirrhosis (PBC) is described in two sisters, one of whom presented with autoimmune thrombocytopenia. Taken together with reports of platelet autoantibodies in PBC this case may indicate a place for immunosuppressive agents in the treatment of thrombocytopenia in PBC.

Abstract
Gastric acid secretion, pepsin secretion, and fasting serum gastrin levels were measured in 23 patients with duodenal ulcer disease, divided into three groups which received either cimetidine 800 mg daily, cimetidine 1600 mg daily, or ranitidine hydrochloride 300 mg daily for eight weeks. Pentagastrin tests were carried out at intervals both before and after treatment. Each dose of cimetidine reduced acid secretion to 42% of control one week after starting therapy. Ranitidine reduced acid secretion to 33% of the pretreatment value. Acid secretion remained suppressed to these levels throughout treatment with each drug. Acid secretion returned to pretreatment levels in all patients one week after treatment and remained normal until the end of the study. Both drugs reduced pepsin, which fell to 64% and 61% (p less than 0.01) after 800 mg and 1600 mg cimetidine respectively and to 65% (p less than 0.005) with ranitidine after one week's treatment. Pepsin secretion remained at this reduced level in both cimetidine groups till the end of treatment. Pepsin levels fell to 50% at two weeks of therapy with ranitidine but stabilised at this level till the end of therapy. Cimetidine withdrawal was followed by a return towards pretreatment levels of pepsin secretion; but secretion remained significantly depressed (p less than 0.05) to the end of the study period. In the ranitidine-treated patients pepsin output returned to normal after drug withdrawal. Fasting gastrin levels rose during treatment with both drugs but failed to reach significant levels. After withdrawal of treatment fasting serum gastrin levels returned to normal in all three groups of patients.

Abstract
In order to assess the performance of the 14C-glycocholic acid breath test as an indicator of bacterial colonisation of the jejunum, 145 combined breath tests and jejunal aspirate cultures were carried out on a total of 50 subjects who had an increased probability of being colonised. Ninety-one of the 145 cultures were positive while only 31 of the breath tests were positive. This poor performance of the breath test relative to the aspirate culture can be predicted with reasonable accuracy from known bile deconjugating capabilities of bacteria found in the small intestine.

Abstract
A technique of microdissection of colonic mucosa has allowed the study of mitotic activity, measured by metaphase accumulation following colchicine blockade, in individual crypts of mouse colon. The changes occurring during growth and development of normal colon have been studied and compared with changes found in antigen free colon (colonic isografts) and in cell-mediated immune damage of the bowel (allograft rejection). Metaphase accumulation was steady at two metaphases per hour in baby mouse colon until 18 days after birth. Between 18 and 24 days a rapid, and significant increase in mitotic activity occurred (P less than 0.01), reached adult values, and changed no further. Metaphase accumulation in isografts was similar to normal colon for the first two weeks after transplantation but the rise in mitotic activity in the third week did not occur. Allografts of colon showed two- to three-fold increases in metaphase accumulation when compared with both normal colon and isografts (P less than 0.01). When crypt mitotic activity was compared with the length of crypts measured in histological sections of normal colon, isografts, and allografts, no clear relationship was observed. Both changes in the luminal environment of the gut at the time of weaning and cell-mediated immune reactions in the colonic wall appeared to be associated with increased mitotic activity in colonic crypts.

Abstract
Lymphocyte subpopulations were measured in the peripheral blood of 13 patients with primary biliary cirrhosis (PBC), 13 with chronic active hepatitis (CAH), and 16 age- and sex-matched normal subjects. A significant, relative and absolute, reduction in activated T cells and K cells, compared with that in normal subjects, was found in PBC but not in CAH. The reduction in K cells observed in PBC was found to be accompanied by a parallel decrease in lymphocyte-mediated antibody-dependent cytotoxicity.

Abstract
Grafts of mouse fetal colon, implanted beneath the renal capsule of adult hosts, have been used to study the growth and development of colonic isografts and the rejection of colonic allografts. Isografts grew normally and maintained a structure similar to normal colon. Grafts between strains with H2 histocompatibility differences were rejected by 13 days after transplantation. Early progressive infiltration of the grafts by lymphoid cells was followed by increasing damage to, and subsequent loss of, the epithelial cell layer and destruction of the underlying muscle, changes which parallel those seen in rejection of skin and small bowel. The increase in survival time which is seen in allografts between strains with H2 identity was longer in the colon than has been seen in the skin or small bowel; none of the allografts of colon were completely rejected before 30 days, and some remained viable at 50 days. Comparison of the appearances of rejection in the colon with those of ulcerative colitis and colonic Crohn's disease does not show the striking similarity which is seen between small bowel rejection and coeliac disease. Many of the individual features of these diseases are, however, present in the course of colonic rejection.

Abstract
In an attempt to demonstrate local cell-mediated immunity (C.M.I.) to gliadin in patients with coeliac disease, fragments of jejunal-biopsy specimens were cultured in the presence and absence of alpha-gliadin and the culture-medium was assayed for its capacity to inhibit migration of normal human peripheral-blood leucocytes (i.e., for a migration-inhibition factor [M.I.F.]). No M.I.F. activity was detected in the culture-medium when biopsy specimens from patients with coeliac disease or controls were cultured without added antigen. However, an M.I.F. was secreted into the culture-medium when biopsy specimens from patients with coeliac disease were cultured with alpha-gliadin. These findings suggest that there is a population of lymphocytes which are sensitised to gliadin in the intestinal mucosa of patients with untreated coeliac disease. They support the theory that a local C.M.I. reaction to gliadin may be the cause of villous atrophy and crypt hyperplasia in coeliac disease.

Abstract
Abstract
Of 9 patients who survived the immediate postoperative period after hepatic transplantation, 6 later died from infection. Pulmonary infection was the major problem. Biliary infection related to bile fistulas may be less in the future with the improved technique of a cholecystdochostomy which was carried out in the last 2 patients. Frequent bacteriaemias were noted and the organisms were often the same as those found in the bile. Most infections were thought to be autogenous. Cytomegalovirus infection occurred in 6 patients, but in none was there evidence that the virus did harm. Broad-spectrum antibiotic therapy was freely used in the earlier patients but was often followed by superinfection with resistant organisms and fungi. The present policy is not only to use antibiotics sparingly but to rely on narrow-spectrum drugs wherever possible.
