    Abstract:
    The aim of this paper was to compare different effects of Tripterygium Glycosides Tablets from 6 different manufacturers on multiple organ injuries in rats and to explore mechanism of hepatotoxicity preliminarily from the perspective of apoptosis and oxidative stress. Rats were randomly divided into the groups normal, Zhejiang, Hunan, Hubei, Shanghai, Jiangsu and Fujian(7 groups with 16 rats in each group, sex in half). Rats were given Tripterygium Glycosides Tablets at 144 mg·kg~(-1)·d~(-1)(16 times the clinical equivalent dose) once a day according to its corresponding group like rats in Zhejiang group was given Tripterygium Glycosides Tablets from Zhejiang manufactures continuously for 20 days with the life and death situation of mice to be observed, then rats were executed to detect various indicators. RESULTS:: showed that 8 female rats in Zhejiang group died after 15 days of administration, the serum NEUT of rats in Hubei, Fujian and Shanghai groups was significantly lower than that of normal rats. The serum AST, ALT and/or TBiL levels were increased in all rats, and serum BUN and/or CRE levels of rats were also increased in Hunan, Hubei, Fujian and Shanghai groups. In dosage groups, testicular and ovarian coefficients of rats were reduced, the number of sperm were significant decreased while the rate of sperm malformation increased and sperm dynamics parameters of normal, especially in Jiangsu and Zhejiang groups. Liver histopathology and apoptosis of liver cells were observed in dosage groups, especially in Jiangsu and Hubei groups. In liver, Nrf2, HO-1 and Bcl-2 were inhibited and the protein expression level of Bax were increased simultaneously in dosage groups. These results showed that all Tripterygium Glycosides Tablets from 6 manufacturers could lead to chronic multiple organ injuries with disparate specialties in rats, and Jiangsu and Zhejiang groups were more toxic. It could be the mechanism promoting mitochondrial mediated Bax/Bcl-2 cell apoptosis signaling pathway and negatively regulating Nrf2/HO-1 oxidative stress signaling pathway that Tripterygium Glycosides Tablets from 6 different manufacturers resulted in chronic liver injury, the results above were for reference only in subsequent study.
