Abstract
The use of lead shotgun ammunition for hunting has been banned in a few jurisdictions and habitats, principally to protect wild birds from poisoning by ingestion of spent lead shot. The EU and UK REACH processes have recently considered bans on lead ammunition throughout the European Union and United Kingdom, including assessments of possible health benefits from reduced human dietary exposure to lead from game meat. Comparisons of the mean lead concentrations in meat from gamebirds killed using lead and non‑lead shotgun ammunition have not been published. We compared lead concentrations in meat from wild-shot pheasants from which lead shotgun pellets were recovered (n = 27) with those from which iron pellets were recovered (n = 20), having removed all pellets from the meat before analysis. The mean concentration of lead in meat from pheasants killed using lead shot was 2.10 mg/kg w.w., which is >20 times the European Union's maximum permitted level for the lead concentration in meat from domesticated animals. For pheasants killed using iron shot the mean was 0.07 mg/kg w.w., which is below the maximum permitted level.

Abstract
Oncocytic neoplasms are most rarely found in the adrenal gland. They are usually benign and non-functioning. We present a case of a testosterone-secreting oncocytic adrenocortical carcinoma in a 19-year-old female who presented with acne, hirsutism and irregular menses. Clinical investigations revealed an elevated testosterone and DHEA-S and a 4×5 cm left adrenal mass. The tumour was successfully excised. The histology showed the tumour to be comprised of oncocytic cells with granular, eosinophilic cytoplasm, features consistent with an oncocytic carcinoma. This is the first case presented of a testosterone-secreting oncocytic adrenocortical carcinoma.

Abstract
AIMS To pilot an educational programme (KICk-OFF) for children and adolescents with type 1 diabetes mellitus (DM). Evaluation included (i) independent assessment of curriculum quality, (ii) acceptability to families and (iii) possible impact on standardised outcome measures (HbA1c, body mass index (BMI), diary reports of hypoglycaemia, quality of life (QoL)). METHODS 48 children aged 11-16 years (mean age 13.60 (SD 1.36) years) were recruited from three UK centres. Six 5-day outpatient courses on carbohydrate counting and insulin dose adjustment were held. Semi-structured interviews were conducted with children and parents before and after the course. Glycaemic control (HbA1c), BMI and frequency of hypoglycaemia were assessed before the course and at 3 and 6 months after intervention. QoL was assessed before the course and at 2 weeks, 3 and 6 months. RESULTS Educational evaluation indicated the course format was appropriate and consistent. Parent and child interviews suggested that pre-course expectations were largely met. There were no changes in HbA1c, BMI or episodes of hypoglycaemia, but children and parents reported improved QoL (p<0.05). CONCLUSIONS KICk-OFF was well-received by children and parents and was associated with improved QoL. In this small pilot study, glycaemic control did not change but findings justify conducting a future randomised controlled trial involving a revised curriculum, a larger study population including a control group and longer follow-up.

Abstract
UNLABELLED Between 2002 and 2004 the Centre of Applied Health Sciences of the University of Lüneburg carried out a research project concerning the cancer screening behaviour of men. Within a standardised survey all men aged 45 - 60 years of a local health insurance company were interviewed by a postal questionnaire about their cancer screening behaviour including their main reasons to engage or not to engage in the (insurance financed) cancer screening tests. 337 questionnaires could be analysed. As a theoretical framework, the "transtheoretical model" of Prochaska et al. was used to characterise the men according to their degree of readiness to engage in cancer screening tests. RESULTS 25% of the men were regularly engaged in cancer screening tests. 40% have been engaged at least once or were in the stage of "preparation" to do so in the near future. 35% were resistant to undergo cancer screening tests. Anxiety concerning the check-up itself or the possibility to have a positive result were the main barriers for men not to engage in cancer screening. As an important factor to overcome such barriers, these men mentioned the need for better communication between doctors and patients. To improve cancer screening behaviour, this was considered more important than general information campaigns or organisational changes concerning the check-ups.

Abstract
Abstract
Background
Normothermic preservation provides metabolic support to an ischaemically damaged organ before use as a kidney transplant. Optimal conditions for ex vivo preservation have not yet been established. This study examined the effects of arterial pressure on renal preservation using isolated haemoperfused kidneys.
Methods
An isolated organ preservation system, developed using cardiopulmonary bypass technology, was used to perfuse porcine kidneys with normothermic oxygenated blood. Groups of kidneys (n = 6) were perfused at a mean arterial pressure of 95, 75 or 55 mmHg.
Results
Kidneys perfused at the higher mean arterial pressures of 95 and 75 mmHg demonstrated improved renal function: mean(s.d.) area under the curve (AUC) for creatinine clearance 71(19) and 55(30) respectively versus 14(12) in the 55-mmHg group, P = 0·002; AUC for serum creatinine 938(140) and 1290(394) versus 2404(595), P = 0·003. The higher perfusion pressures were also associated with better acid–base homeostasis and improved renal haemodynamics.
Conclusion
Mean arterial pressures of either 95 or 75 mmHg were capable of sustaining physiological renal function, but kidneys in the 95-mmHg group demonstrated superior renal function overall.

Abstract
BACKGROUND The present study was conducted as part of an ongoing project to develop an innovative educational intervention for young people with type 1 diabetes. We aimed to seek the views of children and adolescents with type 1 diabetes and their parents regarding (i) the acceptability of the new programme and (ii) practical aspects regarding course design and delivery. METHODS Twenty-four children and 29 parents attended one of eight separate focus groups. Semi-structured interview schedules were developed around two main areas of discussion: views on the education programme; and views on the design and delivery of current and future education. Discussions were tape-recorded and transcribed, before undergoing systematic qualitative analysis. RESULTS Participants agreed that the proposed intervention was feasible, and were enthusiastic that it could improve quality of life and 'normality'. Potential problems included self-management during school-time and parental anxiety. In terms of course design/delivery, participants emphasized the need to maximize enjoyment on the course (e.g. integrating fun and practical sessions, holding parts of the course outside of the clinic setting), and encourage effective learning and adherence to the regimen (e.g. including separate parent education, and using IT-based reference material). CONCLUSIONS The qualitative methodology proved an effective way of eliciting child and parent views and informing the development of the proposed intervention. These findings can now be incorporated into the development of the education programme.

Abstract
From 1999 to 2001 the "Centre of Applied Health Sciences" (University of Luneburg) carried out a research project in cooperation with the Psychiatric Hospital Hacklingen in Luneburg and the department of social psychiatry and psychotherapy of the Hanover College of Medicine. The project covered the prevalence of mental disorders among the residents of nursing and geriatric homes in the district of Uelzen including different aspects of medical, psychiatric and nursing care. The research was based on a survey including all residents of these institutions. The response rate was 925 of a total of 1,100 residents. Results showed that three-quarters of the residents had considerable and different psychiatric symptoms and that almost half of the residents suffered from symptoms of dementia. The provision of health care as well as nursing care for these residents are considerably deficient. Care facilities are hardly of therapeutical standard and guidelines. This refers in particular to treatment with psychoactive drugs. The (few) comparable studies show that -- with the exception of some pilot projects -- the situation in the district of Uelzen may be similar to that in other regions of Germany.

Abstract
People with social problems and risks very often also suffer from health problems and risks. This refers to at least 10% of the population. We were interested to learn how many articles in the leading German journal of Public Health "Das Gesundheitswesen" are dealing with this topic of social inequality and health. From 1990 to 1999 just 5.4% of the 1399 published articles deal with this topic. The authors mainly came from social epidemiology; practical research was rare. This also seems to be a consequence of a lack of research in the departments of social work education.

Abstract
We have investigated vitamin C supplementation effects on immunoglobulin oxidation (carbonyls) and total plasma protein sulfhydryls in healthy human volunteers. After receiving placebo, plasma ascorbate and oxidation markers were unchanged. Following 5 weeks supplementation with vitamin C (400 mg/day), plasma ascorbate increased but no significant effect on protein oxidation was observed. At 10 and 15 weeks supplementation, carbonyl levels were significantly reduced (P < 0.01) in subjects with low baseline ascorbate (29.51 +/- 5.3 microM) but not in those with normal baseline ascorbate (51.81 +/- 2.3 microM). To eliminate any effect from seasonal variation in dietary antioxidant intake, a second phase was undertaken. Subjects on vitamin C for 15 weeks were randomly assigned to receive either placebo or vitamin C. No difference in plasma sulfhydryl content was observed. Subjects withdrawn from supplementation showed an increase in immunoglobulin carbonyl content (P < 0.01). This demonstrates that dietary vitamin C supplementation can reduce certain types of oxidative protein damage in subjects with low basal antioxidant.

Abstract
The increased risk of atherosclerosis in nephrotic syndrome is attributable in part to the associated hyperlipidaemia. The importance of oxidation of LDL in the atherogenic process has been recognized over the last 15 years. However, there are few data on the balance of antioxidant defences and lipoprotein oxidation in nephrotic syndrome. Plasma antioxidant vitamin concentrations and indices of LDL oxidation (LDL lipid hydroperoxide content and the susceptibility of LDL to oxidation) were measured in two groups of patients; group I comprised 29 nephrotic patients and group II comprised 25 patients with haematuria. Plasma ascorbate concentration was significantly lower in group I (the nephrotic group) compared with group II (median 13.3 versus 22.2 micromol/L; P<0.001). Vitamin E concentrations were higher in group I but were not significantly different if corrected for total plasma cholesterol (6.12 versus 5.88 micromol/mmol; P=0.33). However, these changes resulted in a low ascorbate:vitamin E ratio in group I (0.19 versus 0.87; P<0.0001). Despite these changes in important antioxidant vitamin concentrations, we were unable to demonstrate any increased susceptibility to LDL oxidation in vitro or any difference in LDL lipid hydroperoxide content. These data suggest that there may be a relative defect of oxidant/antioxidant balance in nephrotic syndrome which could predispose to increased oxidative stress. However, measures of LDL oxidation were not significantly different between the two groups. LDL was protected from oxidation despite the severe hyperlipidaemia and the low circulating vitamin C concentrations.

Abstract
Our hypothesis is that rotation increases apoptosis in standard tissue culture medium at shear stresses of greater than approximately 0.3 dyn/cm2. Human MIP-101 poorly differentiated colorectal carcinoma cells were cultured for 6 d in complete medium in monolayers, on Teflon-coated nonadherent surfaces (static three-dimensional [3D]) or in rotating 3D cultures either in microgravity in low-earth orbit (3D microg) or in unit gravity on the ground (3D 1g). Apoptosis (determined morphologically), proliferation (by MIB1 staining), and the expression of epidermal growth-factor receptor (EGF-R), TGF-alpha, or TGF-beta were assessed by immunohistochemistry, while the expression of the differentiation marker carcinoembryonic antigen (CEA) was assessed on Western blots. Over the course of 6 d, static 3D cultures displayed the highest rates of proliferation and lowest apoptosis. This was associated with high EGF-R, TGF-alpha, and TGF-beta expression which was greater than that of a monolayer culture. Both rotated 3D lg and 3D microg cultures displayed lower expression of EGF-R, TGF-alpha, or TGF-beta and proliferation than that of monolayer or static 3D cultures. However, rotated 3D microg displayed significantly less apoptosis and greater CEA expression than rotated 3D 1g cultures. When rotated cultures of MIP-101 cells were grown uncler static conditions for another 3 d, proliferation increased and apoptosis decreased. Thus, rotation appears to increase apoptosis and decrease proliferation, whereas static 3D cultures in either unit or microgravity have less apoptosis, and reduced rotation in microgravity increases CEA expression.

Abstract
Microscopic infarcts develop within the livers of athymic nude mice during the first 24 h after human colorectal carcinoma (CRC) cells arrest within hepatic sinusoids. Because these regions are reperfused, essentially all weakly metastatic clone A and MIP-101 CRC cells die, whereas many highly metastatic CX-1 CRC cells survive. Because hepatic sinusoidal endothelial cells kill tumor cells in vitro by producing nitric oxide, superoxide anion, and other reactive oxygen and nitrogen species, our purpose was to determine whether reoxygenation of ischemic hepatic cultures in vitro forms toxic oxygen and nitrogen radicals that kill weakly but not highly metastatic CRC cells. CRC cells (10(7)) were labeled with rhodamine-dextran and calcein AM, cultured with cells from one mouse liver in a rotating suspension culture system for up to 24 h, and the metabolic activity of the CRC cells was determined. Liver fragments oxygenated normally before harvest were not toxic to either CRC cell line, but coculture with liver made ischemic by a 3-min ligation of the portal vein and hepatic artery in vivo before harvest and then cultured in oxygenated medium killed 50-70% of weakly metastatic clone A and MIP-101 cells at 24 h but <15% of highly metastatic CX-1 cells. Inhibition of nitric oxide synthase, addition of exogenous superoxide dismutase, but not catalase or hypoxia, during coculture blocked the killing of weakly metastatic CRC cells. Thus, reoxygenation of hepatic parenchymal and nonparenchymal cells after ischemia may form toxic species that eliminate weakly metastatic CRCs within 24 h of their arrest in the liver.

Abstract
The numbers of autopsies performed at the Institute of Pathology in Chemnitz before and after German unification (1990) were compared (1987-1992). In 1991 and 1992 a decrease of up to 40% was observed. In the former GDR an autopsy was possible without agreement of the relatives, whereas since unification the relatives have the power to forbid an autopsy. This was the principal reason for the dramatic decline in the past 2 years. Another relevant factor is the difficult economic situation of most hospitals in the region, preventing the arrangement of more autopsies. Analysis also shows the important role of physicians in clinics regarding the autopsy rates.

Abstract
To assess the prevalence of growth problems among school entrants in an urban population who were not preselected on poverty or other nutritional risk criteria, we analyzed height and weight measurements for 5170 4- and 5-year-old children (91.9% black, 5.5% white, and 2.6% Hispanic) who enrolled in District of Columbia public school kindergartens in the Fall of 1985. Compared to the National Center for Health Statistics reference, the white girls and boys were of average height, Hispanic girls were of average height, and Hispanic boys were shorter than average. The black girls and boys were taller than average. In light of published evidence for black-white differences in the timing and duration of growth, we tentatively attributed this tall stature to advanced skeletal maturation of the black children relative to the predominantly white United States population growth standards. Underweight was virtually absent in this population. Excess overweight was noted in all sex-racial/ethnic subgroups, particularly among Hispanic children. However, the extent to which overweight (high weight-for-height percentile) represents obesity in kindergarten-aged children and in different racial/ethnic groups needs clarification before the implications of the finding of excess overweight can be fully understood. Overall, the growth of these children was on a par with the National Center for Health Statistics growth reference population.

Abstract
The endodontic antiseptics chloramine, sodium hypochlorite and chlorhexidine digluconate were evaluated for antimicrobial effect by a complex of susceptibility testing. In the agar diffusion test, tube dilution test and plate flooding test chlorhexidine digluconate was the most efficient agent against isolates of infected root canal.

Abstract
At German universities and colleges social and community medicine is mainly taught by lecturers from various medical fields. Accordingly a great variety of topics are presented and different focuses are set. Thus orientation becomes more difficult for the students. The present paper was elaborated by experienced lecturers. It contains proposals for the organization of the lessons. With regard to the topics a list of priorities is presented and criteria for the qualification of the lecturers are formulated.

Abstract
The effects of the 5-HT receptor antagonist, metergoline, on the prolactin and growth hormone responses to intravenous L-tryptophan were assessed in seven normal subjects. Pretreatment with metergoline lowered baseline prolactin concentration and abol ished the increase in prolactin following L-tryptophan. In contrast, neither baseline nor the response to L-tryptophan was altered by metergoline. These results are consistent with the proposal that the prolactin response to L-tryptophan is mediated by 5-HT(1) receptors; however, metergoline might also reduce prolactin responses by a dopaminergic action. The nature of the 5-HT receptor involved in the growth hormone response to L-tryptophan remains to be identified.

Abstract
Denatured calf-thymus DNA was X-irradiated, coupled to methylated bovine serum albumin and injected into rabbits to study the possible formation of specific antibodies. The serological activity was tested by a modified Farr-test, a micro complement binding reaction and by caesium chloride isopycnic ultracentrifugation. It was found with all assays that the immunological reaction was mainly due to unspecific DNA-binding and only a very small amount to radiation products. It seems, therefore, that this approach is not suitable for the analytical investigation of DNA damage produced by ionizing radiation.

Abstract
The effect of N-methyl-N-nitrosourea (MNU) on the cell cycle, DNA synthesis and chromosomal sensitivity of cultivated diploid fibroblasts and fibroblasts with trisomy 21 was investigated in vitro. With the exception of the inhibition of G2, Down's cells proved to be more sensitive than diploid cells with respect to the decrease of the mitotic and labelling index, the inhibition of the progression of cells through the early and middle S and the frequency of induced chromosomal aberrations. The chromosomal sensitivity was dependent on the position of cells in the cell cycle during treatment with MNU. If treated during late S no differences concerning the S block and aberration frequencies were found between diploid and Down's cells. However, if MNU treatment took place in the middle and early S, Down's cells were more sensitive. The higher aberration frequencies in Down's cells resulted from elevated levels of chromatid breaks, multiple fragmentations and chromatid translocations. Possible reasons for the increased sensitivity of Down's cells are discussed.

Abstract
The ultraviolet-induced inhibition of rRNA synthesis has been measured during the first hour after irradiation for stationary yeast cells differing in radiation sensitivity. rRNA was isolated and separated on an agarose-polyacrylamide gel. The wild type and a mutant which is possibly defective in recombinational repair show a sigmoidal inhibition curve, an excision-deficient mutant shows an exponential one. From these curves it is deduced that a pyrimidine dimer acts as a transcription terminating lesion as was shown for bacteria. During the first hour after irradiation the excision repair system decreases the number of transcription terminating lesions by 22% in the wild type and 25% in the mutant defective in recombinational repair. An approximation of the repair efficiency gives a value of 7500-10 000 transcription terminating lesions per cell being removed during the first hour after irradiation by excision. Ultraviolet-induced lesions of this kind can partially be removed by photoreactivation. The inhibition coefficients are the same for 26 S and 18 S rRNA in stationary cells, whereas exponentially growing cells show different inhibition coefficients for 26 S and 18 S rRNA leading to the suggestion that the processing of the ribosomal precursor RNA is different in stationary and exponentially growing cells.
