摘要: Changes in lipid composition were examined peritoneal polymorphonuclear leukocytes (PMNL) from rats with streptozotocin-induced diabetes. The largest changes associated the lipids PMNL prepared insulin-dependent diabetes mellitus found of fatty acids phospholipids although no consistent noted amounts individual classes. relative amount arachidonic acid was significantly reduced and that linoleic increased diabetic rats. extent A23187-stimulated release CGP IGP much smaller than normal PMNL. Moreover, there decreases production free its metabolites, such as LTB4 5-HETE by compared to Aggregation provoked A23187 suppressed However, addition or those resulted aggregation similar extents, a result supports role for enhanced availability endogenous induction present results suggest diabetes-associated metabolism might play critical modulation
