Faecal lipids in familial adenomatosis coli   总被引:1,自引:0,他引:1  
Faecal sterols and bile acids from six patients with familial adenomatosis coli (FPC) and 61 healthy men were analysed preoperatively. Faecal concentrations and secretion of neutral sterols, plant sterols, and degradation products of cholesterol were identical in the two groups. No increase was found in the faecal bile acid excretion, and the distribution of individual bile acids was normal in FPC. The results suggest that the development of adenomas in FPC is not associated with abnormal cholesterol and bile acid excretion.  相似文献

There are no systematic and complex investigations regarding the hemorheologic action of the betablockers propranolol and talinolol. The results on the other ones are contradictory. On the basis of a critical survey of the literature, in-vitro-experiments and studies in animals (rats) and humans may conclude that there are no remarkable deteriorations of rheological parameters in the therapeutic dose range. This is valid for diseases only where the haemodynamic regulation doesn't prevail.  相似文献

A randomly selected sample of 120 women, born in 1906-1907 and living in the city of Gothenburg, were invited to an ultrasound examination for gallstone disease. One hundred and nine subjects participated in the study, and among these, 24% gave a history of a previous cholecystectomy, 27% had gallstones, and 49% had no stones in the gallbladder. Among the women with stones in the gallbladder only 35% had associated symptoms. The design of the study enabled a comparison among women with no stones in the gallbladder, with gallstones, and with a previous cholecystectomy. Women with gallstones, previous or present, had a higher body weight, body mass index, skinfold thickness, and serum triglyceride level than subjects without gallstones.  相似文献

OBJECTIVE: To compare the ability of various methods of staging and grading to predict survival in proximal colon cancer. DESIGN: Retrospective study. SETTING: University hospital, Finland. SUBJECTS: 153 patients with primary proximal colon cancer. MAIN OUTCOME MEASURES: Staging by four classification systems, grading by two grading systems, and survival analysis based on Kaplan-Meier survival curves. RESULTS: In all staging systems the survival curves of different stages differed significantly from each other. The modified Dukes' classification was still the best predictor of survival. Grade of tumours had no significant effect on long term survival, but short term survival was affected adversely by the presence of anaplastic tissue. Tumours with no mucin had a worse prognosis than those that produced mucin. All staging methods were superior to either of the histological grading systems tested as prognosticators. Tumour depth correlated with the operator's clinical impression of radicality of operation, and also predicted survival. CONCLUSION: The clinicopathological modified Dukes' staging system was the most powerful prognosticator in proximal colonic cancer and its use in clinical practice should continue. Even a small amount of anaplastic tissue (> or = 5%) had an adverse effect on short term survival.  相似文献

Sixty-six patients with uretero-ileostomy were investigated with special regards to local status of the urinary stoma, i.e. stomal site, length, size/shape, and peristomal skin. Each variable was defined. In reports from other centres there has been a lack of definitions making it difficult to compare results from different studies. One fifth of our patients had inadequately located stomas and 85% had stomas shorter than 1 cm. The peristomal skin status was assessed according to CPS, Classification of Peristomal Skin. Eight per cent of the patients exhibited severe erythematous/erosive lesions and one fifth pseudoverrucose lesions. The relation between skin lesions and local status of the urinary stoma was analyzed. Patients with inadequately located stomas were more likely to show severe erythematous/erosive lesions and there was a tendency towards patients with stomas shorter than 1 cm, more frequently exhibiting pseudoverrucose lesions.  相似文献

Gastric teratoma is a very rare benign tumor. Fifty-three cases, only two of which were females, have previously been reported. This report concerns two cases of teratoma arising from stomach. One of them is the third female case described in the literature.  相似文献

Renal tubular sodium and water handling determined by the lithium clearance technique, plasma concentrations of atrial natriuretic peptide (ANP), angiotensin II, aldosterone, arginine vasopressin (AVP), and urinary excretion of prostaglandin E2 (PGE2) were determined both during basal conditions and before and after intravenous sodium loading with a 2.5% sodium chloride solution in patients with polycystic kidney disease (PKD), ten with normal or slightly reduced kidney function (PKDN) and seven with moderately reduced kidney function (PKDR), and in 15 healthy controls. In PKDN tubular function was normal, whereas in PKDR both proximal and distal reabsorption of sodium and water were reduced. Angiotensin II and aldosterone were normal in both groups of patients. During basal conditions ANP was higher in PKDR than in PKDN. PGE2 was significantly higher in PKDR than in PKDN. For all patients significant correlations were found between GFR and both ANP (rho = -0.51, n = 17, P less than 0.05) and PGE2 (rho = -0.53, n = 17, P less than 0.05). It is concluded that renal sodium handling is normal in the early stages of PKD. With deterioration of kidney function both proximal and distal tubular reabsorption of sodium is reduced and the accompanying changes in ANP and PGE2 may be compensatory phenomena counteracting declining glomerular filtration rate.  相似文献
