96 patients with gallstones have been treated for up to four years with chenodeoxycholic acid in daily doses of 500, 750, or 1000 mg. None of the patients started on 500 mg daily showed complete gallstone dissolution. 8 out of 41 patients on 750 mg daily had complete dissolution of their radiolucent gallbladder stones after six or more months, and a further(More)
The effect of lactulose on faecal pH and ammonia has been studied in three normal subjects with the aid of dialysis of faeces in vivo. Observations were also made with sodium sulphate and the two hexahydric alcohols, mannitol and sorbitol, given in doses sufficient to cause a similar increase in stool weight. All four cathartics rendered the stool more(More)
Nineteen patients who received chenodeoxycholic acid 750 mg/day for six months had duodenal bile aspirated before and after treatment. In five patients with hypertriglyceridaemia but no gallstones cholesterol saturation was reversed in every case, the mean cholesterol saturation index (SI +/- standard deviation) changing from 1-38 +/- 0-31 to 0-68 +/- 0-06(More)
The effects of four different doses of ursodeoxycholic acid (250, 500, 750, and 1000 mg daily) on biliary lipids were studied in 24 patients with radiolucent gallbladder stones. There was a significant increase in the proportion of ursodeoxycholic acid in bile after all doses, being greatest with 750 and 1000 mg daily. Unsulphated lithocholic acid was also(More)
Fasting primary bile acid conjugates were measured in 44 women by radioimmunoassay methods. Bile acid values were significantly greater in the 21 women who were in the first half of the menstrual cycle than in the 23 women in whom blood was sampled during the second half of the cycle. Similar measurements were made at weekly intervals after menstruation in(More)
1. A 25% faecal suspension in sodium chloride solution, incubated anaerobically at 37 degrees C for 48 h, showed excellent survival of all the main groups of faecal bacteria. 2. All faecal incubation systems studied generated large amounts of ammonia, particularly those in which bacterial counts fell during incubation. As normal faeces contain negligible(More)
Serial serum amylase and blood glucose levels were measured in 68 hypothermic (rectal temperature 35 degrees C or less) patients, including 15 who had hypothermic myxoedema (serum protein bound iodine 3.5 mug/100 ml or less). Raised amylase levels were found in 34 patients and probably reflected a mild acute pancreatitis. The high amylase levels correlated(More)
1. The composition of urine-faeces mixture in seven patients with ureterosigmoid anastomosis has been studied by a dialysis in vivo method using cellulose bags. Urine-faeces dialysate obtained from these patients contained much greater amounts of both bicarbonate and total ammonia than has been reported for faecal dialysate in normal subjects. 2. Total(More)
