A 44-year-old woman is described with an endocrine tumour arising in the kidney. There were associated abnormalities of small intestinal morphology, motility, and absorptive function. These abnormalities reversed on removal of the tumour. Detailed studies showed that the tumour contained, and was secreting, glucagon. It is postulated that the intestinal(More)

Since the subject of intestinal adaptation was last reviewed (16, 20, 97), there have been relatively few major advances but many useful minor additions and extensions which have helped to consolidate our knowledge of the field. The aim of this chapter is to summarise the results of a series of experiments which build up to our present state of knowledge.(More)
BACKGROUND/AIMS The development of cholesterol gallstones, in some patients, has been associated with increased proportions of deoxycholic acid in the bile acid pool. Deoxycholic acid is a microbial product of cholic acid 7alpha-dehydroxylation in the intestines. The levels and activities of bile acid 7alpha-dehydroxylating bacteria have been reported to be(More)
Hypercholesterolaemia has been predicted as a possible complication of chenodeoxycholic acid treatment for gall stones. To exclude this, fasting serum lipids were measured in patients with stones before and at monthly intervals for six months after starting chenodeoxycholic acid. Before treatment half of a group of 36 patients with presumed cholesterol gall(More)
1. To establish the speed on onset of jejunal and ileal mucosal hypoplasia and hypofunction in parenterally fed rats, we measured three indices of mucosal mass, three mucosal enzymes and quantitative histology after 3, 6, 10 and 15 days of total parenteral nutrition and compared the results with those in two orally fed control groups, one with and one(More)
Administration of a single 1 g dose of neomycin sulfate to five healthy subjects simultaneously with a test meal caused a marked increase in the proportion of fatty acid and bile acid in the ultracentrifuged deposit of aspirated intestinal contents. Labeled cholesterol was precipitated in a similar manner in two hypercholesterolemic patients. Neomycin had(More)
BACKGROUND Transgenic mice with a bovine growth hormone gene linked to a mouse metallothionein I promoter (growth hormone transgenics) are a model of chronic growth hormone excess. METHODS Growth of small bowel mucosa in ad libitum-fed growth hormone transgenics and wild type littermates and in growth hormone transgenics pair fed with wild-type(More)
