Despite the hepatotoxic effects of Rifampicin (RIF), its use is inevitable in the management of tuberculosis. No satisfactory treatment is available for prevention of this adverse effect. This study was undertaken to evaluate the protective effect of Nigella sativa extract (NSE) against Rifampicin induced sub-chronic hepatotoxicity. Male wistar rats were divided in 4 groups of 8 each and received vehicle, RIF (100 mg/ kg), RIF (100 mg/kg)+NSE (250 mg/kg) or RIF (100 mg/kg)+NSE (500 mg/kg) orally respectively for 28 days. Blood was withdrawn at day 14 and 28 for estimation of circulatory liver markers and anti-oxidant levels. At the end of the experiment histopathological study and estimation of SOD, CAT, GSH and LPO in liver samples was done. Pre-treatment of NSE produced significant hepatoprotection by decreasing the level of serum Alkaline phosphatase (ALP) (p< 0.01), Serum glutamic pyruvic transaminase (SGPT) (p< 0.001), Serum glutamic oxaloacetic transaminase (SGOT) (p<0 .001="" action="" advocate="" against="" along="" and="" another="" architecture="" bilirubin="" bridging="" by="" cat="" changes="" chronic="" degeneration="" degenerative="" drug="" extending="" fatty="" from="" further="" group="" groups="" gsh="" hepatocytes="" hepatoprotective="" hepatotoxicity.="" hepatoxicity.="" histopathology="" in="" increasing="" indicate="" induced="" infiltration="" is="" its="" kg="" level="" levels="" liver="" mda="" mg="" microvesicular="" mononuclear="" near="" necrosis="" needed="" normal="" nse="" of="" one="" p="" persisting="" portal="" possesses="" pre-treatment="" prevention="" regaining="" research="" results="" rif="" serum="" showed="" sod="" span="" steatosis.="" sub="" that="" the="" to="" tract.="" tract="" triditis="" use="" with="">
