Immuno histological evidence of ormocarpum sennoides dc extract in the expression of bax and bcl2 in wister rats with glucocorticoid induced osteoporosis

Abstract

Introduction: Glucocorticoid therapy is the most common cause for secondary osteoporosis leading to a resurgence of interest in traditional medicine that could have bone sparing effects by naturally occurring bioactive molecules. Therefore, this study was done to evaluate the effect of Ormocarpum sennoides DC through immunohistological evidence in the expression of Bax and Bcl2 in glucocorticoid-induced Osteoporosis in Wister albino rats. Materials and Methods: Rats were divided into five groups (Control, MPA (Osteoporosis), Alendronate (2 mg/kg), 100 mg (EOS), and 200 mg (EOS). The treatment was conducted for 45 days the Bax and Bcl2 expressions were evaluated in osteoclast of distal femur diaphysis. Results: When compared the MPA to control group (P < 0.05) Bax increased and Bcl2 reduced, when compared with MPA (P < 0.05) Alendronate, EOS 100 mg and EOS 200 mg increased the Bcl2 expressions, Alendronate, EOS 100 mg, and EOS 200 mg reduced the Bax expression. Discussion and Conclusion: EOS 100 mg and EOS 200 mg increased Bcl2 expression and reduced the Bax expression Ormocarpum sennoides prevents glucocorticoid-induced Apoptosis of preosteoblast; therefore, Bcl2 may be an important regulator of bone growth thus reporting antiapoptotic property of Ormocarpum sennoides DC.
