Evaluation of the effects of Calliandra portoricensis extracts on oxidative stress (antioxidant) enzymes was carried out using wistar rat model. The anti-oxidant enzymes evaluated were superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx). These extracts were used to ascertain their potency in enhancing these enzymes activities in envenomed rats. A total of 30 rats were randomly assigned into 5 treatment groups of 6 rats each. Group 1 (control) received nothing. Group 2 received viperian venom only. Groups 3, 4 and 5 received same amount of venom in addition to calculated doses of flavnoid-rich, polyphenol-rich and whole ethanolic extracts respectively. The dosages of the venom and the C. portoricensis extracts were administered intramuscularly. After about 4 hours, the rats were sacrificed, serum collected and the oxidative stress enzymes assayed. Marked decrease of SOD, CAT and GPx enzymes activities occurred in the group 2 rats while increases (P<0.05) were observed in groups 3, 4 and 5 experimental rats. These findings suggest that C. portoricensis extracts actually attenuated the obliterating effects of the viperian venom on the naturally-occurring anti-oxidant enzymes in experimental wistar rats. Keywords: Calliandra portoricensis, Venom, Oxidative stress enzymes.
