Chronic excessive alcohol consumption could induce serious liver injury. In this study, therapeutic effect of aqueous methanol extract of L. flowers (BCE) (Family: Bombacaceae) was investigated against hepatic steatosis. This study included seven groups, and the research period was eight weeks. The first group served as control. The six remaining groups were divided into two categories, three groups in each. The first category was fed fat diet. The second category was fed fat diet and orally administrated ethanol, which was given in graduate doses from 2 g/kg/d to 6 g/kg/d. Then, one group from each category was orally treated with the standard drug fluvastatin (2 mg/Kg/d). Another group was orally treated with BCE (200 mg/kg/d). The third group left untreated. The results revealed that BCE significantly decrease both the body and liver weight. The treatment with BCE extract also ameliorates the effect of alcohol induced increase of liver enzyme activities. In addition, the extract was significantly increased hepatic liver antioxidants and decreased malondialdehyde (MDA) level. Also, serum lipid profiles: triglycerides (TG), total cholesterol (TC) and low density lipoprotein (LDL) were significantly decreased after BCE treatment. Histopathological study showed fatty changes induced by alcohol which were improved by BCE treatment. These data suggest that the BCE has anti-inflammatory, anti-oxidant and anti-steatosis potential properties against alcohol induced liver damage. This may be due to the presence of flavonoids and other phenol compounds.
长期过量饮酒会导致严重的肝损伤。在本研究中,对木棉科木棉花的甲醇水提取物(BCE)治疗肝脂肪变性的效果进行了研究。本研究包括七组,研究周期为八周。第一组作为对照组。其余六组分为两类,每组三组。第一类给予高脂饮食。第二类给予高脂饮食并口服乙醇,乙醇剂量从2 g/kg/d递增至6 g/kg/d。然后,每类中的一组口服标准药物氟伐他汀(2 mg/Kg/d)进行治疗。另一组口服BCE(200 mg/kg/d)进行治疗。第三组不进行治疗。结果显示,BCE显著降低了体重和肝脏重量。BCE提取物治疗还改善了酒精诱导的肝酶活性升高的影响。此外,该提取物显著提高了肝脏抗氧化剂水平并降低了丙二醛(MDA)水平。同时,BCE治疗后血清脂质谱:甘油三酯(TG)、总胆固醇(TC)和低密度脂蛋白(LDL)显著降低。组织病理学研究表明,酒精诱导的脂肪变化经BCE治疗后得到改善。这些数据表明,BCE对酒精性肝损伤具有抗炎、抗氧化和抗脂肪变性的潜在特性。这可能归因于黄酮类化合物和其他酚类化合物的存在。
