1. The present study investigated regulation of reflex excitability after experimental contusion injury of the spinal cord. 2. Four measures of H-reflex excitability were evaluated in normal rats and at 6, 28, and 60 days after contusion injury at the T8 level: 1) reflex thresholds, 2) slope of the reflex recruitment curves, 3) maximal plantar(More)
Fatty livers resembling those seen in the early stages of kwashiorkor have been produced in primates. Monkeys were fed, for about 1 year, purified diets free from choline and betaine and low in methionine. Supplementation with choline slightly improved food consumption and gain in weight. Choline prevented the appearance of any stainable lipide in the liver(More)
Conflicting reports concerning the hepatic effects of interleukin-1 beta (IL-1 beta) and tumor necrosis factor alpha (TNF alpha) in the metabolic response to injury led us to investigate the influence of physiological concentrations of these cytokines on amino acid metabolism in the isolated perfused rat liver. IL-1 beta was ineffective at a concentration(More)
