Objective:To evaluate the effect of aqueous seed extract of Solarium suratlense(S.suraltense)on the oxidative potential of cauda cpididymal spermatozoa.Methods:S.surattense seed extract was orally administered at the dosage of 10 mg/kg b.w.for 15 days,after which aspartate transferase(AST),alanine transferase(ALT),glutamate dehydrogenase(GDH),citric acid and isocitrate dehydrogenase(ICDH)were assayed.Results:The activity levels of the enzymes AST and ALT,which are considered to be the androgenicity in the sperm suspension,were depleted in the extract fed rats.The activity level of the enzyme ICDH,was reduced significantly in the treated group(P<0.00l).Conclusions:It can be concluded that the oral administration of the aqueous seed extract of S.surattense can deplete the oxidative stress of cauda epididymal spermatozoa in albino rats. Objective: To evaluate the effect of aqueous seed extract of Solarium suratlense (S. sacuraltense) on the oxidative potential of cauda cpididymal spermatozoa. Methods: S. surattense seed extract was orally administered at the dosage of 10 mg / kg bwfor 15 days, after which aspartate transferase (AST), alanine transferase (ALT), glutamate dehydrogenase (GDH), citric acid and isocitrate dehydrogenase (ICDH) were assayed. Results: The activity levels of the enzymes AST and ALT, which are considered to be the androgenic in the sperm suspension, were depleted in the extract fed rats. The activity level of the enzyme ICDH, was reduced significantly in the treated group (P <0.00l). Conclusions: It can be concluded that the oral administration of the aqueous seed extract of S.surattense can deplete the oxidative stress of cauda epididymal spermatozoa in albino rats.
