Human intestinal folate conjugase: adaptation after jejunoileal bypass.
During intestinal absorption, dietary polyglutamyl folates are hydrolyzed to monoglutamyl folates by pteroylpolyglutamate hydrolase (folate conjugase). This enzyme is present in the brush border and intracellular fractions of human jejunal mucosa. We compared the activities of brush border and intracellular folate conjugase (BBFC and ICFC), and other mucosal enzymes in the jejunum in continuity...

After the operation, the patient developed marked weight loss, vomiting, hepatic failure, and a bizarre mental state with sudden losses of consciousness.

متن کاملRectal hyperplasia after jejunoileal bypass for morbid obesity.
Jejunoileal bypass (JIB) has been widely used to treat patients with morbid obesity for the past 20 years. In rats JIB causes adaptive colonic hyperplasia and enhances colorectal neoplasia. In this study crypt cell production rate (CCPR) was measured stathmokinetically in cultured rectal biopsies from nine patients with JIB and seven controls without intestinal operations or disease. Crypt cell...
متن کاملThe effect of jejunoileal bypass on the pharmacokinetics of digoxin in man.
Seven subjects who underwent jejunoileal bypass surgery for massive obesity participated in a study to examine the relative bioavailability of digoxin before and one to two months after surgery. They were given a loading dose of 1 mg digoxin in divided oral doses followed by oral maintenance doses of 0.5 mg daily. There were no significant differences in the area under the serum concentration t...
