摘要: 目的探究海南鲜椰子水对酒精性肝损伤大鼠的保护作用。方法采用56°白酒灌胃,建立大鼠酒精性肝损伤模型。取大鼠26只,随机分为椰子水处理组9只,模型组9只和正常组8只。给予椰子组和模型组动物白酒灌胃,同时给予椰子组椰子水自由饮用,给予正常组动物0.9%生理盐水灌胃,给予模型组和正常组蒸馏水自由饮用,均连续29 d。采用硫代巴比妥酸法检测肝组织匀浆丙二醛(MDA)含量,采用羟胺法检测肝组织匀浆超氧化物歧化酶(SOD)含量。结果在实验结束时,模型组动物血清AST水平为(123.0±36.2) U/L,显著高于正常组和椰子组【(86.5±21.0) U/L和(96.9±26.0) U/L,P<0.05】,但不同组间血清ALT和TG水平差异无统计学意义(P>0.05);模型组肝组织匀浆MDA含量为(0.479±0.069) nmol/mg,显著高于椰子组【(0.258±0.078) nmol/mg,P<0.01】和正常组【(0.311±0.139) nmol/mg,P<0.01】;椰子组和模型组SOD含量分别为(0.068±0.008) U/mg和(0.071±0.010) U/mg,显著高于正常组【(0.044±0.022) U/mg,P<0.05】,但椰子组与模型组SOD含量差异无统计学意义(P>0.05);模型组大鼠肝细胞脂肪变性较轻,肝小叶中心带肝细胞中出现大小不等的脂肪滴,个别有肝淤血;椰子组大鼠肝小叶结构正常,肝细胞结构完整、清晰。结论椰子水对酒精性肝损伤具有一定的保护作用,机理可能与其抗氧化作用有关。

Abstract: Objective To investigate the protective effect of Hainan fresh coconut water on alcoholic liver injury in rats. Methods Hepatic injury in rats was induced by daily administration of white spirit with alcohol concentraion of 56% by gavage for 29 days. Thirty Sprague-Dawley rats were randomly divided into model group (n=9),control group (n=8) and coconut water group (n=9). The animals in control was given 0.9% saline and in experimental group was given alcohol plus Hainan fresh coconut water. At the end of the experiment,the rats were sacrificed and blood and livers were collected. The histopathological change in liver was revealed by HE staining and the levels of alanine aminotransferase (ALT),aspartate aminotransferase (AST),triglyceride (TG) in blood and the content of superoxidedismutase(SOD) and malondialdehyde(MDA) in hepatic homogenates were detected. Results Serum AST levels in model group was (123.0±36.2) U/L,significantly higher than that in control group [(86.5±21.0) U/L,P<0.05] or in coconut water group [(96.9±26.0) U/L,P<0.05];there was no significant differences in serum ALT and TG levels among the three groups (P>0.05);the MDA level in model group was higher than that in control group or in coconut water group [(0.479±0.069) nmol/mg vs. (0.258±0.078) nmol/mg and(0.311±0.139) nmol/mg,P<0.01 for both];the SOD levels in coconut water group and model group were higher than in control group[(0.068±0.008) U/mg and (0.071±0.010) U/mg vs. (0.044±0.022) U/mg,P<0.05 for both],but there was no difference in SOD level between coconut water group and model group;Mild fatty degeneration of hepatocytes was observed in model group and fat droplet were found from hepatocytes in centrilobular regions with some hepatic congestion,however,the histology in coconut water group revealed regular hepatic lobules with intact and distinct hepatocyte structure. Conclusion Hainan fresh coconut water has certain protective effect against alcoholic liver injury in rats,and its antioxygenation might be involved in this process.
