- Department of Medicine, Sahlgren's Hospital, University of Göteborg, Sweden. SOS (Swedish obese subjects) is an on-going intervention trial designed to determine whether the mortality and morbidity rates among obese individuals who lose weight by surgical means (gastric banding, vertical banded gastroplasty and gastric by-pass) differ from the rates associated with conventional treatment. For this purpose, the study is recruiting a sample of obese men and women who constitute a registry of potential subjects from which the participants are drawn. Eligibility criteria for participation in the registry were: age at application 37-57 years and BMI greater than or equal to 34 kg/m2 for men and greater than or equal to 38 kg/m2 for women. Before receiving a health examination, all patients complete extensive questionnaires on current and past health status, utilization of medical care and medications, socio-economic status, psychological profiles, dietary habits, physical activity, weight history, and familial disposition to obesity. Each surgical case is matched to its optimal control in the registry, to ensure that the two groups do not differ systematically with respect to any of 18 matching variables that may affect prognosis. The first 1006 subjects included in the registry have been studied with respect to morbidity and compared with on-going population studies of men and women in Göteborg, Sweden. The relative risks of prevalent disease and symptoms associated with obesity in 50-year-old males and females respectively were 4.3 and 4.7 (dyspnoea), 14.7 and 11.8 (angina), 6.3 (myocardial infarction, males only), 2.1 and 4.5 (hypertension), 5.2 and 6.6 (diabetes), 4.6 and 26.1 (claudication) and 1.7 and 1.8 (gall bladder disease). Correspondingly, obese males and females display elevations of systolic and diastolic blood pressure, fasting glucose, insulin, triglyceride, and uric acid levels. However, total cholesterol was not increased in obese males and was in fact significantly lower in obese compared with reference women. HDL-cholesterol was lower in obese than reference men (data were not available in reference women). The rate of taking sick pensions was over twice as high in SOS obese patients than in population controls. Finally, comparison of measurements with self-reported prevalence estimates revealed a considerable amount of previously undiagnosed hypertension and diabetes in the obese subjects. These data suggest that the excess health risks associated with obesity may not be fully appreciated. PMID: 1322873 [PubMed - indexed for MEDLINE]

Adaptation of signal transduction in brain

- Cell culture models were used to study the effects of long-term ethanol exposure on neuronal cells. Effects on phospholipase C and phospholipase D mediated signal transduction were investigated by assaying receptor-binding, G protein function, activities of lipases, formation of second messengers and c-fos mRNA. The signal transduction cascades displayed abnormal activities from 2 to 7 days of exposure which differed from the acute effects. Phosphatidylethanol formed by phospholipase D is an abnormal lipid that may harmfully affect nerve cell function.

Presence of polymorphonuclear granulocytes during the early stage of transplant arteriosclerosis after prolonged ischemia in the rat
- 1994

Ingår i: Transpl Int. ; 7 Suppl 1, s. S371-5

Tidskriftsartikel (refereegranskat)abstract
- The presence and function of polymorphonuclear granulocytes has been investigated, in particular, in the microcirculation in many short-term models of ischaemia/reperfusion injury. The aim of this study was to examine the presence of granulocytes in the aorta in a recently established long-term model of transplant arteriosclerosis, based on prolonged cold graft ischaemia time in the rat. Aortic grafts of PVG donors were subjected to two different cold ischaemia times of 1 and 4 h (n = 5 in each group) before an orthotopic transplantation to syngeneic recipients. The grafts were explanted shortly after various times post-reperfusion (7.5 min 24 h) and examined with conventional staining, immunohistochemistry and transmission electron microscopy for the presence of granulocytes. The results showed the presence of these cells adherent to the endothelial layer or in the subendothelial layer in grafts with both ischaemia times and with a maximum seen 2 h after transplantation. The internal elastic lamina was interrupted at sites of granulocyte adherence. We concluded that the polymorphonuclear granulocyte may be involved in the ischaemia/reperfusion injury in this model, thus, contributing to the development of accelerated transplant arteriosclerosis.
