Mechanism of Action of Rhubarb on Intrahepatic Cholestasis in Infantile Rats / 实用儿科临床杂志

ABSTRACT

Objective To explore mechanism of action of rhubarb on intrahepatic cholestasis in infantile rats.Methods Ninety Sprague-Dawley(SD)infantile rats were randomly divided into 5 groupstreatment group of rhubarb,untreated group,treatment control group 1 of ursodeoxychlic acid(UDCA),treatment control group 2 of UDCA and deltasone,and control group not treated with ?-naphthyl isothiocyanate(ANIT)and any other treatments.Jaundice model of intrahepatic cholestasis was established in infantile rats by ANIT.At the time of the 2nd,3rd,and 4th week,the concentrations of serum total bilirubin(TB),direct bilirubin(DB),ALT,alkaline phosphatase(ALP),total bile acid(TBA)and TBA were assessed by automatic biochemical analyzer.The concentrations of nitrogen monoxide(NO),maleic dialdehyde(MDA)and the ability of total antioxidation(T-AOC)in liver tissues were measured.Results It was demonstrated that the animal model of hepatic jaundice with cholestasis was successfully established.The levels of serum DB,TB,ALP,ALT and TBA were significantly lower in the treatment group of rhubarb compared with those in the untreated group(Pa
