title: Experimental osteoporosis induced in female albino rats and its antagonism by Indian black scorpion (Heterometrus bengalensis C.L.Koch) venom.
abstract: The present study was designed to explore the antiosteoporosis activity of the Indian black scorpion (Heterometrus bengalensis) venom on experimental osteoporosis female albino rats. Sham operated control rats were designated as Gr I, Gr II animals served as osteoporosis control, Gr III osteoporosis rats were treated with SV (1/25th of MLD), Gr IV osteoporosis rats were treated with 1/50th of MLD of SV and Gr V osteoporosis rats were treated with standard (calcium and vit-D3). As compared with the Gr I rats, the Gr II rats showed typical osteoporosis changes in increased of urinary Ca(2+), PO(4)(3-), CRE, OH-P levels, serum/plasma Ca(2+), PO(4)(3-), TRAP, IL1, IL6, TNFalpha and PTH level, bone Ca(2+), PO(4)(3-), Mg(2+), Zn(2+) and decreased level of serum/plasma ALP, EST and PTH, bone Na(+). In Gr III, Gr IV and Gr V rats, the osteoporosis changes of urine, serum and bone, were significantly restored as compared with the Gr II rats. The bone dimensions, morphology and histological changes observed in Gr II rats were restored in Gr III, Gr IV and Gr V rats. This study confirms that the Indian black scorpion venom may influence bone remodeling process by stimulating bone formation and reducing bone resorption process of osteogenesis.
