Garlic capsule and selenium-vitamins ACE combination therapy modulate key antioxidant proteins and cellular adenosine triphosphate in lisinopril-induced lung damage in rats

Abstract

AbstractGarlic capsule (GAR) and/or selenium- vitamin A, C, E (S-VACE) might be useful in the treatment of lung diseases. The present study evaluated the toxicity of lisinopril (LIS) in the lungs of male rats and the reversal effect of GAR and/or selenium-vitamins A, C, and E (S-VACE).Group I served as the control, whereas animals in groups II, III, IV, and V received 28 mg of LIS/kg body weight by gavage. Group III was co-treated with GAR at a therapeutic dosage of 250 mg/kg body weight per day. Group IV was co-treated with S-VACE at dosage of 500 mg/kg body weight per day. Lastly, group V was co-treated with GAR and S-VACE at dosages of 250 and 500 mg/kg body weight per day, respectively. The experiment lasted for 8 days (sub-acute exposure).Administration of therapeutic dose of LIS to male rats depleted enzymatic antioxidants (superoxide dismutase and catalase) and cellular adenosine triphosphate content with concomitant increase in lipid peroxidation. Histopathology examination showed damage to the epithelial cells of the airways. These effects were prevented by both single and combination treatment of GAR and S-VACE in male rats with LIS-induced lung toxicity.We therefore concluded that the combination of GAR and S-VACE can be a novel therapy for the management of lung diseases in humans.
