Abstract:
[Objective]To investigate the changes and correlation of bone collagen and biomechanical property in osteoporosis rats.[Method]Normal 30 nullimating female 7 month SD rats were divided randomly to two groups,each included 15.The sham group was unovariectomized,and the OVX group was ovariectomized.To execute the rats after 12 weeks,the author get the 5th lumbar vertebra,and then detected the biomechanical property and HYP.The author observed the collagen morphology of the 4th lumbar vertebra using the microscope after the masson triad color dyeing.[Result]Twelve weeks later,HYP in the sham group was(0.197?0.035)mg/g.The bone collagen was regular,compact,and closed succession.HYP in the OVX group was(0.182?0.022)mg/g.The bone collagen was incompact,thin,collapse and poor succession.There was significant change of the HYP in two groups(P
