proximal metaphysis meaning in Chinese

近侧干骺端

In ovx rats , not only bone mineral density ( bmd ) of lumbar vertebrae in vivo and vitro , but also bmd of femora ( except for r3 region ) and proximal metaphysis ( r1 region ) in vitro decreased obviously ( p < 0 . 01 ) ， whose bone loss rates of l5 and l6 were the highest and achieved 13 % ; the trabeculae of ovx rats were few ， fine , and discontinued and there were lacunae on the surface ; in ovx rats , both compressive strength of vertebral bodies and the mechanical properties of femora decreased ; the falling degree of the former was greater ; the maximal compressive power of lumbar vertebrae decreased with 33 . 32 %
结果显示：大鼠卵巢切除后，活体、离体腰椎以及股骨（除r3区）、胫骨近端干骺端（ r1区）的离体骨密度显著下降（ p < 0 . 01 ），离体l5和l6的骨丢失率最大，达13 % ；骨小梁减少、变细，连接中断，骨小梁表面有吸收陷窝；腰椎压缩强度和股骨力学性能均下降，前者更明显，腰椎最大压缩力下降率达33 . 32 % 。
