| 摘 要： | 为研究高钼对雄性绵羊骨骼病变的影响,将12只健康雄性小尾寒羊随机分为3组,Ⅰ组饲喂基础日粮,Ⅱ组在基础日粮基础上添加30mg/kg钼,Ⅲ组在基础日粮中添加60mg/kg钼。试验第180天,剖杀羊只,取肱骨、桡骨、掌骨、股骨、胫骨、跖骨进行X线平片拍摄,利用双能X线骨密度检测仪对右侧股骨进行骨密度检测。结果表明:Ⅱ组、Ⅲ组与Ⅰ组相比,肱骨、桡骨、掌骨、股骨、胫骨、跖骨骨皮质变薄,且髓腔密度降低,肱骨、股骨骨小梁变稀疏;Ⅱ组、Ⅲ组与Ⅰ组相比股骨颈、大转子、髓腔、沃氏三角区及整体股骨骨密度差异极显著(P<0.01);Ⅲ组与Ⅱ组相比股骨颈、沃氏三角区及全骨骨密度降低显著(P<0.05)。研究结果提示,30mg/kg钼与60mg/kg钼均能导致骨皮质变薄,骨小梁变稀疏,髓腔密度降低,以四肢长管骨最为明显;且均能导致右侧股骨不同部位骨密度降低。

| Abstract: | To investigate the effect of high molybdenum on bone in male sheep,twelve healthy male Small Tail Han sheep were randomly divided into three groups and animal models were established by feeding diet with different doses of molybdenum of 0 mg/kg(group Ⅰ),30 mg/kg(group Ⅱ) and 60 mg/kg(group Ⅲ) for 180 days.At the end of the experiment,all of the sheep were killed for making X-ray film of the humerus,radius,metacarpal,femur,tibia and metatarsus and detecting the bone density of the right femur by dual-energy X-ray detector.The results showed that compared to group Ⅰ,the cortical bone of the humerus,radius,metacarpal,femur,tibia and metatarsus of groups Ⅲ and Ⅱ was thinner and the medullary cavity density of them was decreased.The trabecular of humerus and femur was thinner too.The density of the neck,roch,inter,ward's,total of group Ⅲ and group Ⅱ significantly decreased(P<0.01).Compared to group Ⅱ,the density of the neck,ward's,total of group Ⅲ was significantly decreased(P<0.05).This indicates that both of 30 mg/kg and 60 mg/kg Mo could cause the cortical bone and trabecular thinner and decrease density of medullary cavity and different parts of right femur. |
