Objective To find the evidence of the effect of microbiotic collagenase in root surface caries by observing the destruction of collagenous matrix on root surface. 目的通过对根面牙骨质基质胶原纤维降解破坏情况的超微结构观察,以寻找微生物源性胶原酶在根面龋中发生作用的证据。
These indicated that the functional electrical stimulation of peripheral nerve could increase collagen synthesis, accelerate mineralization of collagenous matrix and shorten ossification process in the callus. 表明早期骨痂内胶原蛋白合成量增加,基质钙化迅速、完全,骨性骨痂发生早、骨转化过程缩短。
Mild hyperplasia of collagenous fiber was presented in the matrix. 髓核基质内轻度胶原增生。
Results They demonstrated that there were difference in the location and function of the collagenous and non collagenous proteins in the development of bone matrix. 结果本研究可见胶原和非胶原蛋白在骨基质发育中的表达部位和作用有所不同;且在氟组的表达均要早于对照组。
The study on the collagenous bone matrix is an important means to reveal the pathogenesis of osteoporosis. 对胶原性骨基质的研究是揭示骨质疏松症发病机理的重要途径。
