BACKGROUND
Croton lobatus contains a high amount of antioxidant phytochemicals that probably account for its wide use as food and medicine in the traditional communities of West Africa.
METHODS
The study evaluated the modulatory role of methanol extract of Croton lobatus leaf on alloxan-induced diabetes and associated cardiovascular complications. Male rats were randomly selected and assigned to one of six groups (A to F) of eight animals each: A (distilled water); B (corn oil); C (Alloxan); D (Alloxan + 100 mg kg-1 Croton lobatus); E: (Alloxan + 200 mg kg-1 C. lobatus); and F (Alloxan + 100 mg kg-1 glibenclamide).
RESULTS
Acute toxicity studies revealed no mortality of rats at the administration of different doses of extract up to the 5,000 mg kg-1 dose. Histology of the pancreas showed focal area of necrosis, and fatty infiltration in diabetic untreated rats, but these lesions were absent in pancreas of rats treated with C. lobatus extract.
CONCLUSIONS
Methanol leaf extract of C. lobatus reduced arteriogenic risk factors, improved antioxidant status, restored the observable pathological lesions associated with experimental diabetes in rats, and thus offers a new therapeutic window as herbal therapy for the treatment of diabetes mellitus and associated cardiovascular complications.
