Abstract

Introduction: Eribroma oblongum (Malvaceae) stem bark is used in Cameroonian ethnomedicine to treat various metabolic illnesses including cardiovascular diseases. The present study was designed to investigate the mechanisms of hypotensive effects of hydroethanolic extract of Eribroma oblongum and its cardioprotective effects after a subchronic treatment. Study Design: This was a prospective cross-sectional analytical study Methodology: Preventive effects were studied after oral administration of hydroethanolic extract of Eribroma oblongum (HEEO) (100 mg/kg body weight/day) or captopril (25 mg/kg body weight/day) simultaneously with L-NAME (40 mg/kg body weight/ day) in rats for 28 days. Body weight and food intake were measured after 5 days. At the end of treatment, blood pressure and heart rate were recorded. Aorta, heart, liver and kidneys were weighted. Reduced nitrite, superoxide dismutase, catalase, gluthatione, Malondialdehyde and lipid profile were measured. Results: The extract prevented L-NAME hypertension and improved food intake and body weight of rats. HEEO improved lipid profile and antioxidant status. L-NAME caused a significant (P<0.001) increase in the levels of serum transaminase relative to the normal. L-NAME treated rats had markedly decreased catalase (CAT), superoxide dismutase (SOD), nitrite (NO2-) and reduced glutathione (GSH) levels in the tissue. Also, L-NAME caused a significant (P<0.001) induction of lipid peroxidation (MDA) in the animals tissue relative to the normal range. Administration of HEEO with L- NAME caused significant (P<0.001) inhibition of MDA relative to LNHR and augmented tissue antioxidant indices. Conclusion: The hydroethanolic stem bark extract of Eribroma oblongum showed a promising potential cardioprotective effect in L-NAME induced hypertension. This effect could be due at least in part by improving endothelial function, lipid profile and oxidative status. These findings justify the traditional use of HEEO as treatment in cardiovascular disorders and serve as a promising traditional pharmacopoeia for the development of new chemical entity in the phytomedicine development platform.
