Abstract: | Summary Stress produced severe mucosal ulcers, increased mucosal microcirculation and lowered mast cell counts in the glandular wall of rat stomachs. Mepyramine i.m. or metiamide i.p. effectively prevented both ulceration and microcirculatory changes but not stress-reduced mast cell counts.Acknowledgment. The authors thank Dr W.A.M. Duncan (Smith, Kline and French Labs Ltd, England) for the generous gift of metiamide. |
