本文观察了浓缩鱼油（ＣＦＯ）对实验性动脉粥样硬化（ＡＳ）形成、血浆及组织胆固醇含量变化、血浆高密度脂蛋白胆固醇（ＨＤＬ一Ｃ）及其代谢酶活性、血小板分泌产物、血液流变学及培养的主动脉平滑肌细胞（ＳＭＣ）增殖的影响。结果显示，ＣＦＯ对实验性ＡＳ形成具有非常显著的抑制作用；ＣＦＯ降低血浆总胆固醇（ＴＣ），同时阻止ＴＣ蓄积于动脉壁和肝脏，ＣＦＯ升高血浆ＨＤＬ一Ｃ，机制是刺激ＨＤＬ合成酶及抑制其降解酶活性；ＣＦＯ抑制血小板分泌血栓素Ａ２（ＴＸＡ２）、５一羟色胺（５一ＨＴ）及钙离子，促进其自身合成环磷酸腺替（ｃＡＭＰ）；ＣＦＯ通过降低血脂和纤维蛋白原水平使全血粘度降低；ＣＦＯ对体外培养的主动脉ＳＭＣ增殖具有显著的抑制作用。
In this paper, the effects of CFO on the formation of experimental atherosclerosis (AS), changes in plasma and tissue cholesterol, plasma HDL-C and its metabolic enzyme activities, platelet secretion products, blood flow Variations and Proliferation of Cultured Aortic Smooth Muscle Cells (SMCs). The results showed that CFO had a significant inhibitory effect on the formation of experimental AS. CFO decreased plasma total cholesterol (TC) and blocked the accumulation of TC in arterial wall and liver. CFO increased plasma HDL-C by stimulating HDL synthase and (CFA) inhibited the secretion of thromboxane A2 (TXA2), 5-hydroxytryptamine (5-HT) and calcium ions, and promoted its own synthesis of cAMP. CFO reduced blood lipids and fibrinogen The whole blood viscosity decreased; CFO on cultured aortic SMC proliferation has a significant inhibitory effect.
