The effects of 85% intestinal resection on the portal somatostatin (SLI) gastric mucosal histamine (HA) and prostaglandin E2 (PGE2)-like activities were studied in guinea-pigs. A considerable increase in gastric mucosal HA-like activity of guinea-pigs subjected to small bowel resection (189.9 +/- 15.0 ng/g tissue) was measured in comparison to control values (42.9 +/- 6.3 ng/g tissue) (p < 0.001). The mean tissue PGE2-like activity in the sham operated group was 1636.9 +/- 128.8 ng/g tissue, whereas in the test group it was 650.5 +/- 59.3 ng/g tissue. After 85% small bowel resection a significant fall in portal and systemic venous SLI values was observed (T = 0, p < 0.05).
