Small bowel bacterial overgrowth in strongyloidiasis.

Small bowel bacterial growth was studied in patients with strongyloidiasis, and the results were compared to controls. We concluded that in strongyloidiasis there is small bowel bacterial overgrowth, and so it should be considered in the pathogenesis of some of the gastrointestinal manifestations and complications of strongyloidiasis.

Bile acids do not regulate the intestinal mucosal cholesterol synthesis: studies in the chronic bile duct-ureter fistula rat model.

Control male Wistar rats with intact bile circulation, animals with a bile duct-right ureter fistula, and bile duct-right ureter fistula rats fed taurocholic acid (5.5 mg/day) were maintained on a cholesterol-free pellet diet and pulse labeled subcutaneously with radioactive cholesterol. Bile acid feeding did not interfere with the synthesis of cholesterol by the intestinal mucosa or by the whole body in spite of markedly lowering the production of bile acids.

[Single nocturnal dose of ranitidine in the treatment of duodenal ulcer: results of an open multicenter, comparative trial].

This prospective multicentric randomized open trial was designed to evaluate the efficacy of ranitidine 150 mg bid vs 300 mg nocte in the short-term (4 weeks) treatment of duodenal ulcer in 15 Brazilian centers. On the basis of a randomization table 190 patients with endoscopically confirmed duodenal ulcer were allocated to receive either ranitidine 150 mg bid (94 pts) or 300 mg nocte (96 pts). The 2 treatment groups were well matched for age, sex, duration of ulcer disease, number and size of ulcers, duration of current episode, intensity of ulcer pain, alcohol and coffee intake and smoking habits.

[Influence of diet composition on the late course of acute pancreatitis. Experimental study in rats].

Acute pancreatitis was induced with sodium taurocholate 1% in two lots of rats fed during 21 days with diets that differed in lipid composition. Serum amylase, pancreatic tissue enzymes (trypsinogen, chymotrypsinogen and amylase), pancreatic tissue nucleotides (RNA and DNA) and biopsies for histological study were collected in normal pair fed animals, and in the experimental lots 1, 4, 7 and 15 days after AP was induced. ANOVA and Student t-test were used for the comparison of biochemical data (p less than 0.

Coffee drinking in patients with duodenal ulcer and a control population.

The ingestion of plain coffee was compared in 150 duodenal ulcer patients (DU) and 100 control subjects without digestive complaints (C). The DU and C groups were registered in accordance with their daily consumption of coffee: none, 1-100 ml, 101-300 ml, 301-500 ml, and more than 500 ml. Fifty millilitres of coffee as prepared in Brazil contain around 50 mg of a caffeine, which is 2.
