The effect of partial hepatectomy (62 +/- 2% of liver mass) or sham laparotomy on the pancreas was studied in rats. Pancreatic contents of DNA, protein, and digestive enzymes were measured 14 days postoperatively. Pancreatic acini were prepared to study exocrine pancreatic function after hormonal stimulation. Islet hormone release was investigated in the isolated perfused pancreas. Liver regeneration reached 93 +/- 1% within 14 days. Water contents in liver and pancreas remained unaltered. Simultaneously, the pancreatic weight increased significantly. Pancreatic enzymes showed a parallel elevation, whereas DNA remained unaffected. Amylase secretion from pancreatic acini was unaltered. Stimulated insulin and somatostatin release from the perfused pancreas were both increased. Plasma cholecystokinin levels were elevated, whereas neurotensin was decreased. Insulin and gastrin remained unchanged. In conclusion, after partial hepatectomy, enhanced cholecystokinin and decreased neurotensin blood levels are suggested to contribute to a hypertrophic effect on the exocrine pancreas and an adaptive regulation of the endocrine gland.

Liver regeneration after omeprazole (OMP) or famotidine (FAM) administration was examined in 66% hepatectomized rats. The regeneration was evaluated by the liver weight as a percentage of body weight (LRR) and the proportion of hepatocytes in mitosis per 1,000 counts (MI). Administration of OMP 0.4 mg/kg per day for 3 or 7 days suppressed LRR and MI 3 and 7 days after hepatectomy. However, the administration of FAM 0.8 mg/kg per day for 3 or 7 days did not change either LRR or MI. Increased gastrin levels in the blood were seen only after OMP administration. The food intake was unchanged by OMP or FAM, but FAM increased water intake. The liver functional score, glutamic pyruvic transaminase and alkaline phosphatase in the blood all increased with OMP, but FAM had no apparent effect on the hepatic or renal function. These observations suggest that a large dosage of OMP suppresses liver regeneration, while FAM appears to have no meaningful effect on regeneration.
