Aim:
The present study was conducted to evaluate the hepatoprotective activity of Tephrosia purpurea (TP) against sodium arsenite (NaAsO2) induced sub-acute toxicity in rats.
Materials And Methods:
Twenty four wistar albino rats of either sex were randomly divided into three groups. Group II and III were orally administered with sodium arsenite (10 mg/kg) daily in drinking water for 28 days. Additionally Group III was orally treated with hydro-alcoholic extract of Tephrosia purpurea (TP) @ 500 mg/kg daily for the same time period, whereas only deionized water was given to Group I (control). Serum biomarker levels, oxidative stress parameters and arsenic concentration were assessed in liver. Histopathology was also conducted.
Results:
It has been seen that TPE (500 mg/kg) significantly (P < 0.01) reduced serum ALT, AST, ALP activity and increased total protein and reduced necrosis and inflammation in liver of group III compared to group II. A significantly (P < 0.01) higher LPO and lower GSH levels without change in SOD activity in liver was also observed in group II compared to group III, though there was no significant difference in arsenic accumulation between them. The plant extract also protects the animals of group III from significant (P < 0.01) reduction in body weight.
Conclusion:
Our study shows that supplementation of Tephrosia purpurea extract (500 mg/kg) could ameliorate the hepatotoxic action of arsenic.
