title: The mechanism of Cordyceps sinensis and strontium in prevention of osteoporosis in rats.
abstract: The effects of Cordyceps sinensis (Caterpillar fungus) and strontium ranelate on ovariectomized osteopenic rats was studied in this paper. After the rats were treated orally with C. sinensis, strontium, and C. sinensis rich in strontium ranelate (CSS) respectively, serum alkaline phosphatase (ALP), tartarate-resistant acid phosphatase (TRAP), serum osteocalcin (OC), homocysteine, C-terminal crosslinked telopeptides of collagen type I (CTX), estradiol, and interferon-gamma (IFN-γ) level were examined. The beneficial effects of CSS on improvement of osteoporosis in rats were attributable mainly to decrease ALP activity, TRAP activity, CTX level, and IFN-γ level. At the same time, CSS also increase the OC and estradiol level in ovariectomized osteopenic rats. This study demonstrates the value of C. sinensis rich in strontium ranelate in the management of postmenopausal osteoporosis in humans.
