Results Among the three groups,the children's rib cartilage had the most blood vessels,the most chondrocytes,well-distributed stain of matrixes,and the type Ⅱ collagen was expressed actively and highest in photedensity.The rib cartilage of teenager group had less blood vessels,unhomogeny distributed stain of matrixes,the enlarged and separated cartilage lacunas.The rib cartilage in adult group showed the least blood vessels,the least chondrocytes.the hyalinization of perichondium,the most deposition of calcium salt,and the type II collagen was expressed at the lowest level in photodensity.

结果 儿童组肋软骨膜血管最丰富，软骨基质染色均匀，软骨细胞数目最多，Ⅱ型胶原蛋白表达最活跃，平均积分光密度值最高；青少年组软骨膜内血管减少，软骨基质染色出现明显的不均质状，软骨陷窝体积变大，并呈分隔状，陷窝内软骨细胞数目减少，II型胶原蛋白表达较儿童组减弱；成人组软骨膜血管、细胞成分明显减少，软骨膜内的纤维成分明显玻璃样变，钙盐沉积较青少年组时明显增多，Ⅱ型胶原蛋白表达较青少年组减弱。

Ten adult mixed breed dogs without significant individual difference were made transverse fracture at bilateral iliopectineal crest 1.5cm above the dome of acetabulum, which were fixed with ATMF'S or steel plate respectively. The animals were sacrificed and specimens were procured at 2, 4, 6, 8 and 12 weeks after operation. Samples from the fracture gaps were investigated by histology of HE and Masson staining, image pattern analysis of new bone formation.

方法］ 选用10只成年杂种家犬，双侧髋臼臼顶上方1.5cm处横形截骨，分别采用ATMFS（骨盆髋臼三维记忆内固定系统）前柱固定器和5孔重建钢板内固定，于术后2、4、6、8、12周处死动物取材，行HE染色、Masson三色法染色组织学检查，图像分析新骨形成积分光密度值，研究不同应力作用模式下的骨盆骨折愈合情况。
