RESUMO
Objective To explore the curative effect of ursodeoxycholi acid on retinopathy of prematurity (ROP) caused by high concentration of oxygen in newborn rats. Methods The model of ROP was established. Neonatal rats were divided into normal control group, ROP model group, low dose ursodeoxycholi acid treatment group (10mg/kg) and high dose ursodeoxycholi acid treatment group (40mg/kg). Rats were sacrificed at days 17. The new retinal vessels were observed and counted under lfuorescence microscope. Results The new retinal vessels in ROP rats were hyperplastic, twisted and unevenly distributed. There was signiifcant difference in the number of new retinal vessels among different groups (P=0.000). The number of new retinal vessels of rats in ROP group, low-dose group and high-dose group was signiifcantly more than that in control group (P=0.000). The number of new retinal vessels in low-dose group and high-dose group was significantly less than that in ROP group (P0.05). Conclusions Ursodeoxycholi acid could inhibit the angiogenesis of retina and could have curative effect on ROP.
RESUMO
Objective To evaluate the therapeutic effect of Ursodeoxycholi acid on the treatment of liver cirrhosis with hepatitis B. Methods Eighty-four patients with liver cirrhosis were randomly divided into 2 groups:42 to the treatment group who were given oral capsules of Ursodeoxycholi acid combined with reduced glutathione,and the other 42 to the control group who received Yinzhihuang intravenously, combined with reduced glutathione. Therapeutic efficacy,liver function and its normalization rate,and score of Child-pugh-Turcotte (CPT)were observed after 4 week treatment and 8 week treatment. Results The therapeutic efficacy had no significant difference between the treatment group and the control group (P>0.05). Compared with the control group, the values of γ-glutamyl transpeptidase (γ-GT), alkaline phosphatase (AKP) and globulin(GLO) of the treatment group decreased more significantly (P<0.05), and the normalization rates of γ-GT and AKP in the treatment group was significantly higher than that in the control group at 8 week. The decreased levels of total bilirubin (TBIL) and direct bilirubin(DBIL) were not significantly different between the 2 groups (P>0.05). At 4 week the decrease level of ALT in the 2 groups was similar (P>0.05), while at 8 week the values of ALT reduced more significantly than that of the control group(P<0.05). The score of CPT of the 2 groups were not different after 4 week and 8 week treatment (P>0.05). Conclusion Ursodeoxycholi acid can obviously decrease the values of γ-GT, AKP and GLO in liver cirrhosis with hepatitis B, which may be related to Ursodeoxycholi acid relieving the injury of bile duct and enhancing biliary transport.
