referral bases of most inflammatory bowel disease studies. The Colitis-Ileitis Study Group of …

Every sttldent of biochemistry has seen, and perhaps even looked at, two-dimensional
metabolic maps that out-line the myriad pathways of biodegrada-tion and biosynthesis. He …

Gastric secretory, psychological, and behavioral observations were carried out in 59
experiments in an infant (with a gastric fistula) from the age of 15 to 20 months. Of a number of …

Partially purified arginase and crystalline alanine aminotransferase are inactivated in a first-order
reaction upon incubation with disrupted lysosomes at pH 5.0. Activity was not obtained …

Rat liver mitochondrial glutamic-alanine transaminase can be distinguished from the
supernatant enzyme on the basis of its markedly greater lability and its nonresponsiveness to …

The activity of the enzyme system which converts hepatic glycogen synthetase to the active
form disappears from the livers of fasted, adrenalectomized rats. The level of active …

Evidence has been summarized which establishes that the increase in rat liver glutamic-alanine
