The effect of prostacyclin and stable thromboxane analog A2 on endothelial culture of human aorta was studied. It was shown that prostacyclin inhibited accumulation of cholesterol in the cells and their proliferation, while thromboxane exhibited an opposite effect. Calcium antagonists potentiated effects of prostacyclin and inhibited them in respect to thromboxane. Screening of a number of synthetic agents affecting arachidonic acid metabolism was carried out. It was found that lipoxygenase inhibitors suppress cholesterol accumulation and proliferation in cells presumably due to enhancement of prostacyclin synthesis and inhibition of leukotriene formation. The balance between various eicosanoids is supposed to be an important factor of atherogenesis regulation, while antiatherogenic effect of calcium antagonists is somehow associated with the impact of eicosanoids on atherogenesis regulation. |
