摘要:

试验旨在研究中草药复合微生态制剂(CHCP)对急性肝脏损伤蛋鸡肝脏的保护作用。试验分两部分:①用四氯化碳豆油(SCCl4)建立蛋鸡急性肝脏损伤模型。选取1 d健康蛋雏鸡108只随机分为4组,模型Ⅰ~Ⅲ组分别按1、2、4 mL/kg体重灌胃10%(V/V)SCCl4,对照组按2 mL/kg体重灌胃豆油,分别在14、28及35 d时各灌胃一次;②CHCP对蛋鸡急性肝脏损伤的影响。选择1 d 健康蛋雏鸡60只随机分为5组:对照组(豆油)、模型对照组(SCCl4)及低、中、高剂量CHCP组(SCCl4+1‰ CHCP、SCCl4+2‰ CHCP、SCCl4+4‰ CHCP),7 d起饮水使用CHCP,14、28 d按2 mL/kg体重剂量给鸡灌胃10% SCCl4。结果表明,按2 mL/kg体重剂量在14、28 d分别灌胃10% SCCl4即可造成蛋鸡肝脏损伤,引起肝细胞脂肪变性,空泡样变严重,核固缩,坏死;与模型对照组相比,低、中、高剂量CHCP组蛋鸡血清谷草转氨酶(AST)含量分别降低4.35%(P > 0.05)、7.57%(P > 0.05)及9.79%(P < 0.05),中、高剂量CHCP组血清谷丙转氨酶(ALT)含量分别降低34.92%(P < 0.01)、36.51%(P < 0.01),血清总胆红素(TB)含量分别降低25.49%(P < 0.01)、27.45%(P < 0.01);蛋鸡肝细胞切片显示CHCP不同剂量组肝细胞充血减轻,未见脂滴空泡,排列整齐,细胞质丰富而均匀。结果表明,本试验所用的CHCP按2‰、4‰饮水使用均能减少肉鸡肝细胞坏死,降低血清转氨酶活性及TB水平,对SCCl4诱导的肝脏损伤有保护作用。

Abstract:

This experiment was conducted to investigate the liver-protective effect of Chinese herbal compound probiotics (CHCP) on acute liver injury layers.One hundred and eight 1 day old hens were divided into 4 groups with 3 replicates in each group and 9 layers per replicate in trial 1.The layers in model groups Ⅰ to Ⅲ were gavaged with 10% (V/V) soybean oil solution of carbon tetrachloride (SCCl4) according to 1,2 and 4 mL/(kg·BW) at 14,28 and 35 d,respectively.The layers in control group were gavaged with 2 mL/(kg·BW) soybean oil.In trial 2,sixty 1 d layers were divided into 5 groups:Control group (soybean oil),model control group(SCCl4)and low-dose,middle-dose and high-dose CHCP group (SCCl4+1‰ CHCP,SCCl4+2‰ CHCP and SCCl4+4‰ CHCP respectively).CHCP were used by drinking water since 7 days.SCCl4 were gavaged according to 2 mL/(kg·BW) at 14 and 28 d.The results showed as follows:The model of layers liver damage could be built by intragastric administration of 2 mL/(kg·BW) 10%(V/V) SCCl4 at 14,28 d respectively,with the signs of hepatic steatosis,severe vacuolar degeneration,nuclear condensation and necrosis.Compared to the model control group,the serum AST levels in low,medium and high dose CHCP groups were decreased by 4.35% (P > 0.05),7.57% (P > 0.05) and 9.79% (P < 0.05),the serum ALT levels in medium and high dose CHCP groups were decreased by 34.92% (P < 0.01),36.51% (P < 0.01),the serum total bilirubin content in medium and high dose CHCP groups were decreased by 25.49% (P < 0.01),27.45% (P < 0.01).The liver cell congestion was reduced to varying degrees in different dose CHCP groups,and the liver cell had no vacuoles,arranged in neat rows,abundant cytoplasm and uniform in different dose CHCP groups.In conclusion,2‰,4‰ CHCP could reduce hepatocyte necrosis,decrease the serum activities of ALT,AST and total bilirubin levels,and had protective effect on hepatic injury induced by SCCl4.
