Modulation of human gastric mucosal adenylate cyclase activity by prostacyclin.

abstract：:Activation of enzyme phospholipase A2 (EC 3.1.1.4), the major liberator of arachidonic acid, has been proposed as a component in the pathogenesis of inflammatory bowel disease. To test the hypothesis that phospholipase A2 activity is increased in ulcerative colitis, enzyme activity was investigated in colonic biopsies...
