摘要
目的：探讨壳聚糖对脂肪肝的防治作用。方法：采用低剂量ＣＣＬ４后肢注射，并高脂饮食复制大鼠脂肪肝动物模型，同时给予不同剂量的壳聚糖防治，观察肝内脂质蓄积情况、肝细胞线粒体膜的流动性及ＭＤＡ含量的变化。结果：４ｍｇ·ｇ～－１·ｄ～－１以上的壳聚糖可明显降低大鼠肝脏ＴＣ、ＴＧ及线粒体ＭＤＡ含量，提高线粒体膜的流动性。结论：壳聚糖可通过减轻肝脏的脂质过氧化并修复线粒体的膜流动性，从而改善脂肪酸的β氧化，达到减轻肝脂变的作用。
Aim: To study the effects of chitosan on hepatic lipids in fatty liver rats. Methods: The rats given a low does of carbon tetrachloride (CCl4) and fed a high-fat diet were treated with chitosan in different doses. Results: When rats were treated with mid dose of chitosan (4mg· g^-1·d^-1), the contents of triglycerde (TG). total cholesterol (TC) in liver decreased significantly, the level of mitochondria malonal-dialdehyde (MDA) was markedly attenuated and the mitochondria membrane fluidity was restored, which compared with model group. Conclusion: Chitosan may decrease the hepatic lipids by reduced the lipid peroxida- tion and restored mitochondria membrane fluidity to improve the mitochondrial beta-oxida- tion.
