摘要
目的观察Ⅲ类矫形治疗对下颌髁突软骨细胞增殖的影响。方法选取青春发育期的雄性恒河猴6只,随机分为1.5月组和3月组。实验组各2只,对照组各1只。实验组戴用Ⅲ类铸造式磁力矫治器,对照组不戴。运用免疫组织化学检测PCNA,分别计算软骨各层PCNA的平均阳性细胞率。结果实验组较对照组前斜面PCNA阳性细胞率增大,而后斜面PCNA阳性细胞率减小。1.5月组较3月组变化明显。结论Ⅲ类矫形力使髁突软骨前斜面细胞增殖活跃,后斜面细胞增殖受到抑制,提示临床在进行Ⅲ类矫形治疗时,选择力的性质、加力方式和大小是非常重要的。
Objective To observe the effect of Class Ⅲ orthopedic treatment on the proliferation of Chondrocyte of mandible.Methods Six male pubescent monkeys were selected,and divide into 1.5-month experimental group,3-month experimental group and control group at random,2 monkeys in each test group and 1 monkey in each control group.And the monkeys in experimental groups wore the Class Ⅲ cast-type magnetic appliance while the monkeys in the control group did not.Expression of protein of PCNA was observed by immunohis...
