Effects of different doses of ferutinin on bone formation/resorption in ovariectomized rats.

Abstract
This study analyzes the effects of different doses of ferutinin on bone loss caused by estrogen deficiency in ovariectomized rats, in comparison with estradiol benzoate. Thirty female Sprague-Dawley rats were ovariectomized and treated for 30 days from the day after ovariectomy. Static/dynamic histomorphometric analyses were performed on trabecular and cortical bone of lumbar vertebrae and femurs. Very low weight increments were recorded only in all F-OVX groups, with respect to the others. Although the great differences in weight, that could imply a decrease of bone mass in F-OVX groups compared to the control ovariectomized group (C-OVX), trabecular bone in lumbar vertebrae did not show significant differences, suggesting that ferutinin, opposing estrogen deficiency, inhibits bone resorption. Newly formed cortical bone was always low in all F-OVX groups and high in C-OVX, suggesting that it is mainly devoted in answering mechanical demands. In contrast, in distal femoral metaphyses, trabecular bone was reduced and the number of osteoclasts was increased in C-OVX with respect to all other groups, suggesting that it is mainly devoted in answering metabolic demands; moreover, ferutinin dose of 2 mg/kg seemed to be more effective than the lower doses used and estrogens, particularly in those skeletal regions with higher metabolic activity. Our results suggest that the role of ferutinin in preventing osteoporosis caused by estrogen deficiency is expressed in decreasing bone erosion; moreover, in all F-OVX groups bone turnover is very low and seems correlated to the trivial body weight increase, which, in turn, depends on ferutinin treatment.
