Using a rodent model of gut ischemia-reperfusion (I/R), we have previously shown that the induction of inducible nitric oxide synthase (iNOS) is harmful, whereas the induction of heme oxygenase 1 (HO-1) and peroxisome proliferator-activated receptor-gamma (PPAR-gamma) is protective. In the present study, we hypothesized that the luminal nutrients arginine(More)
BACKGROUND We have shown that both intraischemic hypothermia and hypertonic saline resuscitation provide dramatic protection against gut ischemia/reperfusion (I/R) injury that is in part mediated by heme oxygenase-1 (HO-1). We therefore hypothesized that induction of HO-1 by hemin would lessen damage and improve function after gut I/R. MATERIALS AND(More)
Small intestinal resection rats are used widely as a malabsorption model, but the immunological changes are unclear. We examined the changes in systemic and mucosal immune status after a small intestinal resection in rats with a controlled nutritional status. Rats had 60% of their small intestine removed. At 5 days after the surgery, spleen cells and(More)
Changes occurring in serotonin neurons during hyperthermia and hyperthermia-induced convulsions were examined by quantiative immunohistochemistry. A marked increase in serotonin immunoreactivity was observed at the rostral and intermediate levels of the neostriatum of mice kept at high temperatures with no convulsions, and a significant reduction in(More)
