Group I - Normal control (distilled water), Group II - water + cyclophosphamide (10 mg/ml in distilled water), Group III – (n-Butanol fraction of Tinospora cordifolia [NBTC] 10 mg/ml in distilled water), Group IV - NBTC (15 mg/ml in distilled water), Group V- NBTC and cyclophosphamide (5 + 10 mg/ml in distilled water), Group VI - NBTC and cyclophosphamide (10 mg/ml each in distilled water) and Group VII - NBTC and cyclophosphamide (15 + 10 mg/ ml in distilled water).^*P< 0.05, ^**P< 0.01, ^***P< 0.001 when compared with normal control. ^aP < 0.05 and ^cP < 0.001 when compared with negative control, cyclophosphamide (10 mg/ml)
