Abstract

Pancreatic exocrine and endocrine function in postpancreatitic rats treated with cholecystokinin (CCK) receptor antagonist loxiglumide was compared with that treated with saline and CCK octapeptide (CCK-8) or with that in normal control rats. Treatment with loxiglumide (50 mg/kgbody weight), CCK-8 (2.5 mu g/kg body weight), or saline (2.5 ml/kg body weight) was given three times a day for 6 days starting 1 day after the induction of acute pancreatitis by a 4-h subcutaneous infusion of 20 mu gk/g body weight/h of caerulein. On day 8, pancreatic exocrineand endocrine function was simultaneously determined following an intravenous injection of a mixed solution of 0.2 g/kg body weight glucoseplus 100 ng/kg body weight caerulein. Basal pancreatic juice flow wassignificantly increased in all of the postpancreatitic rats irrespective of the treatment, whereas the maximal juice flow in the loxiglumide- and saline-treated rats was significantly low compared with the CCK-8-treated and the control rats. Basal and the peak protein outputs inthe loxiglumide-treated rats were comparable to those in saline-treated rats, but were lower than those in the control or the CCK-8-treatedrats. Although serum glucose concentrations in all of the postpancreatitic rats were similar to those in the control rats, stimulated as well as basal insulin release tended to be high compared with the control rats. In particular, loxiglumide-treated rats showed the exaggeratedinsulin response compared with other groups of rats. These present observations indicate that administration of high dose of loxiglumide for a long period decreases pancreatic enzyme output and causes insulin resistance.
