观察了慢性食饵性高脂血症家兔血中6-酮-PGF_(1e)、血栓素B_2(TXB_2)及血清总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白(HDL)的变化及回心草对其影响,结果发现:慢性食饵性脂血症家兔血浆6-酮-PGF_(1e)水平明显下降,TXB_2水平明显升高,血清TC、TG水平明显提高、HDL水平明显下降。回心草可显著降低高血脂家兔的TC、TG水平,提高HDL水平,可抑制6-酮-PGF_(1e)水平的降低、TXB_2水平的提高,维持二者的平衡。 Observed 6-keto-PGF_(1e), thromboxane B_2(TXB_2), serum total cholesterol (TC), triglyceride (TG) and high-density lipoprotein (HDL) in chronic predilection hyperlipidemia rabbits. The changes and the effects of risotto on the results showed that the level of plasma 6-keto-PGF_(1e) in rabbits with chronic predilection-lipidemia was significantly decreased, the level of TXB_2 was significantly increased, and the levels of serum TC and TG were significantly elevated and HDL levels were elevated. Obvious drop. R. officinalis can significantly reduce the levels of TC and TG in hypercholesterolemic rabbits, increase HDL levels, inhibit the decrease of 6-keto-PGF_(1e) levels, increase the level of TXB_2, and maintain the balance between the two.
