目的:研究前庭破坏和尾吊对大鼠股骨远端松质骨骨密度和微结构的影响,探讨前庭功能对失重状态下骨重建的影响。方法:选用15只SD雌性大鼠,随机分为3组,即对照组,尾吊组和前庭破坏并尾吊组,每组5只。采用戊巴比妥那麻醉大鼠,消毒后向内耳注射对氨基苯砷酸盐0.1 ml(100 mg/ml)来实
Objective: To study the effect of vestibular destruction and caudal hang on the cancellous bone mineral density and microstructure of distal femur in rats, and to explore the effect of vestibular function on bone remodeling under weightlessness. Methods: Fifteen SD female rats were randomly divided into three groups: control group, tail suspension group and vestibular destruction and tail suspension group, with 5 rats in each group. Rats were anesthetized with pentobarbital, and disinfected to the inner ear with p-aminobenzene arsenite 0.1 ml (100 mg / ml)
