protein diet supplemented with methionine, but further supplement of threonine partially prevented liver lipid accumulation . Supplements of leucine, phenylalanine or histidine slightly lowered the liver lipid accumulation of rats fed the nonprotein diet containing methionine . On the other hand, free fatty acid in the plasma was not changed when rats were fed the nonprotein diet supplemented w...

HE SEPARATION of protein from nonprotein material, a usual procedure in the analysis of biological specimens, has been effected in a ilumber of ways. Marymont and London (1) have reported a new coagulalation technic which is perhaps advantageous in certain instances, as well as several applications of the technic (2-6). it is well known that the precipitation of proteins by any of the conventio...

Myocardial sulfhydryl (SH)-containing compounds, including reduced glutathione (GSH), are both defenses against and potential markers of reactive oxygen metabolite injury during ischemia and reperfusion. We examined the alterations in GSH and other myocardial SH pools during reperfusion in anesthetized dogs exposed to brief (15 minutes, n = 7) or prolonged (90 minutes, n = 6) regional ischemia ...

l-Canavanine, the guanidinooxy structural analog of l-arginine, is an important nonprotein amino acid of many leguminous plants with nitrogen storage a major proported role. l-[Guanidinooxy-(14)C]canavanine, [(14)C] urea, and [(15)N]urea were injected separately into the fleshy, green cotyledons of 9-day old jack bean plants, Canavalia ensiformis (L.) DC. [Leguminosae]. There was significant tr...
