Abstract
Background: Cardiospermum halicacabum L. proved to have anti-inflammatory, antihyperglycemic, antioxidant, antiglycation, analgesic and antipyretic activities. It also has been used in Ayurveda and folk medicine for the treatment of rheumatism, fever and earache.
Objective: The present study was aimed to evaluate the effect of Cardiospermum halicacabum leaf extract (CHE) on membrane-bound ATPases in streptozotocin (STZ)-induced diabetic rats.
Methods: Diabetes was induced in male albino Wistar rats by intraperitonial administration of STZ (40 mg/kg BW). CHE (200 mg/kg BW) or glibenclamide (600 mu g/kg BW) was administered orally once daily for 45 days to normal and STZ-induced diabetic rats.
Results: The activities of membrane-bound ATPases such as total ATPase, Na+/K+-ATPase, Mg2+-ATPase and Ca2+-ATPase were significantly decreased in erythrocytes and tissues of STZ-induced diabetic rats. Oral administration of CHE to diabetic rats significantly increased the activities of these enzymes towards near normalcy.
Conclusions: Thus, the present study indicates that the beneficial role of membrane-bound ATPases in STZ-induced diabetic rats. The antihyperglycemic, antioxidant and antihyperlipidemic properties of CHE could be helpful to maintain the activities of membrane-bound ATPases in STZ-induced diabetic rats showing the membrane stabilizing property of extract.
