First-line antituberculosis drugs, namely, isoniazid (INH), rifampicin (RIF), and pyrazinamide (PZA), contribute to diverse pathological complications. Testicular toxicity is one such complication.DC is an herb with potentially curative characteristics. The aim of this study was to test whether extract ofDC (Berberidaceae) has curing potential against testicular toxicity. Characterization of extract was done using ultra-performance liquid chromatography along with acute toxicity testing. Antioxidant activity of extract was checked by DPPH inhibition assay and HOscavenging assay. Rats were dosed once daily for 28 days in groups: control group (saline), toxicant group (30.85 mg/kg body weight INH + 61.7 mg/kg body weight RIF + 132.65 mg/kg body weight PZA), treatment groups (TB drugs + 150/300 mg/kg body weight extract) and standard group (TB drugs +100 mg/kg body weight silymarin). Spectrophotometricevaluations of lipid peroxidation (LPO), reduced glutathione (GSH), superoxide dismutase (SOD), glutathione-S-transferase (GST), and catalase (CAT) content in testes were done using standard protocols. DNA fragmentation and histopathological studies were performed to check the damage at the cellularlevel. Acute toxicity studies revealed LD>5 g/Kg body weight ofextract. ICfor DPPH free-radical scavenging activity and HOscavenging assay were 44.78 µg/mL and 85.28 µg/mL, respectively. Results revealed significant increase in thiobarbituric acid reactive substances, decrease in glutathione and different antioxidants levels, DNA fragmentation pattern, and changes in histology in toxicant group. All the changes were absent in high-dose (300 mg/kg body weight) extract treatment group. This work proved thatextract has protective efficacy against testicular damage caused by anti-TB drugs.
