A cell strain steadily secreting monoclonal antibody against BMP was obtained by hybridoma technique. The monoclonal antibody specifically reacts with the cells of human bone and tooth germs on paraffin embedded tissue sections. Immu-nohistochemical staining shows that BMP is distributed in collagen fibres in normal bone, new osteoid tissue, osteoblasts and the cells of bone icarrow. BMP may also be found in human tooth germs, predentin, the cells of outer and inner enamel epithelium, and the cells...

A cell strain steadily secreting monoclonal antibody against BMP was obtained by hybridoma technique. The monoclonal antibody specifically reacts with the cells of human bone and tooth germs on paraffin embedded tissue sections. Immu-nohistochemical staining shows that BMP is distributed in collagen fibres in normal bone, new osteoid tissue, osteoblasts and the cells of bone icarrow. BMP may also be found in human tooth germs, predentin, the cells of outer and inner enamel epithelium, and the cells of dental sac generating alveolar bone. The results prove that antigenic determinants are the same in both the human and bovine BMP. BMP active inhibition test suggests that tins antibody may block the function group of BMP. The ability of the monoclonal antibody to detect antigen and inhibit generation of new bone ma 'kes it poten tially useful in purification of BMP and treatment of os teosarcoma and other bone diseases.

作者用杂交瘤技术获得了纯系细胞株,能稳定分泌抗BMP单克隆抗体。该抗体能与人的骨和牙胚发生反应,具有很高的特异性。免疫组化染色结果表明,BMP存在于骨基质的胶原纤维、新生的骨基质、骨母细胞和骨髓中的未分化间充质细胞中;在人的牙胚中,BMP主要分布在前期牙木质、外釉细胞和造釉细胞以及形成牙槽骨的牙囊细胞中,表明骨的生长和形成以及牙齿的发育都与BMR密切相关。bBMP-McAb能与人的骨和牙胚发生反应,证实人和牛骨的BMP的抗原决定簇是相同的。BMP活性阻断实验证明,新研制的单克隆抗体能有效地封闭BMP活性基因。利用bBMP McAb这一特点,不仅可以纯化BMP,而且可以用来抑制骨的生长,为临床治疗骨肉瘤和其它骨疾病开拓了广阔的前景。

Transforming growth factor and bone morphogenetic protein(BMP) were relat-ed to embryonic development and differentiation of cells, In this study, the expression of both TGF-β andBMP in 40 cases of ameolblastomas was observed using immunohistohemistry。 The results showed that,TGF-β was detected in both tooth germs and ameloblastomas , but BMP was found only in tooth germs,Itindicated that, overexpression TGF-β might be associated with the development of ameloblastomas , theabsence of BMP in ameloblastomas...

骨形成蛋白和转化生长因子作为生长因子,与胚胎发育及细胞的分化有关。本研究利用免疫表型分析技术检测了40例造釉细胞瘤及正常牙胚中骨形成蛋白及转化生长因子的表达与分布。结果发现,正常牙胚及造釉细胞瘤中均含丰富的转化生长因子,尤以造釉细胞瘤显著;牙胚的造釉细胞、造牙本质细胞、牙乳头细胞均含有丰富的骨形成蛋白,但造釉细胞瘤中骨形成蛋白的检测均为阴性。说明造釉细胞瘤中转化生长因子过量表达,骨形成蛋白表达量过低,或者其分子结构发生了改变。

Periapical inflammation was induced in monkey primary molars for two months. The pathogenesis of apical periodontitis in primary is similar to permanent molars. No inflammatory cells could be seen in the bifurcate radiolucent areas. 48 primary molare of six monkeys were treated by the root canal therapy or the modified pulp mummification. After six months, there was no statistically significant difference(P>0.05) between the success rates of both treatment. If the periapical inflammation was disappearing, there...

Periapical inflammation was induced in monkey primary molars for two months. The pathogenesis of apical periodontitis in primary is similar to permanent molars. No inflammatory cells could be seen in the bifurcate radiolucent areas. 48 primary molare of six monkeys were treated by the root canal therapy or the modified pulp mummification. After six months, there was no statistically significant difference(P>0.05) between the success rates of both treatment. If the periapical inflammation was disappearing, there was no deteriorative effect upon the tooth germs. Otherwise,the inflammation stimulated the enamel epithelium to proliferate or destroy. In this experiment, the mummifying paste in the modified pulp mummification could not fix the necrotic pulp tissue, in most instance, the inflammation could not be disappeared, but could make the inflammation localized in the root canal.

通过猴乳磨牙尖周病模型的复制,表明与恒牙尖周病相近.而根分叉的骨质稀疏区。并无炎症细胞浸润.通过对乳磨牙尖周炎分别进行根管治疗术和变异干髓术治疗,术后6个月。两者疗效无显著差异.治疗后炎症消退,则对牙囊和牙胚无明显影响。否则可影响牙胚的缩余釉上皮.发生形态改变.变异干髓术的干髓剂尚不能完全固定腐败坏死的牙髓组织,只能使炎症局限,多不能完全消失。
