The effects of intestinal resection and diet on the digestive and metabolic utilization of phosphorus were studied in adult rats from which 50% of the distal small intestine had been removed and in sham-operated controls. Metabolic parameters were measured both 1 and 3 months after surgery. The loss of half of the distal small intestine led to a decline in(More)
The influence of intestinal resection and type of diet on nutritive utilization of magnesium was studied in rats in which 50% of the distal small intestine was removed and in sham-operated controls. Nutritive parameters were analyzed after feeding the rats different diets for one or three months after surgery. Loss of 50% of the distal small intestine(More)
The influence of diets containing different types of fat (olive oil or a mixture of 1/3 medium chain triglycerides, 1/3 sunflower seed oil and 1/3 olive oil), and the effect of ursodeoxycholic acid, an exogenous bile acid, on the digestive and metabolic utilization of fat and on the relative percentages of fatty acids in serum in adult rats with 50% distal(More)
The effects of different types of dietary fat on the digestive and metabolic utilization of protein were studied in rats with 50% resection of the distal small intestine and in sham-operated controls one month after surgery. The digestive utilization of protein was not significantly affected in intact animals when olive oil was replaced by butter as the(More)
The nutritive utilization of calcium was studied in adult rats in which 50% of the distal small intestine (DSI) had been resected and in sham-operated controls one month and three months after the operation. Resection of half the DSI reduced the digestive utilization of Ca as reflected by mineral content in bone. Three months after resection, nutritive(More)
The influence of the quality of dietary fat on digestive and metabolic utilization of fat, serum levels of cholesterol and triglycerides and the relative percentages of serum fatty acids was studied in rats in which 50% of the distal small intestine (DSI) was resected and in sham-operated controls. Nutritive parameters were measured 1 month after surgery.(More)
The effects of time and the type of dietary fat on biliary physiology in rats with 50% resection of the distal small intestine was investigated. The effects of ursodeoxycholic acid as an exogenous source in bile acid added to the diet were also studied. The fat composition of all diets was the same in quantitative terms (4%), and differed only in the type(More)
The effects of different types of diet and resecting 50% of the distal small intestine on the digestive and metabolic utilization of protein were studied in resected rats and sham-operated controls. Nutritional parameters were analyzed at 1 and 3 months postsurgery. Intestinal resection led to a deterioration in digestive utilization of protein, which(More)
By adapting the technique of coagglutination to the Groupamatic, we have developed an efficient rapid method of phenotyping donors for the Kell and Fya antigens. 340 specimens can be tested per hour; 800 tests can be performed with only 15 ml of antisera. Over 10,000 donor specimens were tested for Kell and 2,470 were simultaneously phenotyped for Fya. No(More)
The effects of the quality of dietary fat, and the influence of ursodeoxycholic acid, an exogenous bile acid, on the digestive and metabolic utilization of fat were studied in rats in which 50% of the distal small intestine was resected. The fat content of the diets was quantitatively equivalent (4%), and differed only in the type of fat: olive oil (diet A)(More)
