Effects of Yunnan Baiyao on the Differentiation of HPDLFs on the Bio-Oss Collagen Scaffold in vivo.

Background: Yunnan Baiyao, as a traditional Chinese herbal remedy with definite curative effect, has recently been proven can promote the proliferation of osteoblasts and differentiation of human periodontal ligament fibroblasts. Bio-Oss scaffold is a porous bone graft material of natural and antigen-free bovine bone origin.

Methods: To observe the effect of Yunnan Baiyao on the differentiation of HPDLFs on the Bio-Oss collagen scaffold in vivo, the HPDLFs-Bio-Oss collagen complex was constructed in vitro, and Yunnan Baiyao aqueous solution was added, respectively.

[An animal experiment study on the effect of periodontitis on atherosclerosis].

Objective: To make an animal periodontitis and atherosclerosis compound model, and to study the effects of periodontitis on atherosclerosis.

Methods: 36 Japan rabbits were randomly divided into four groups: Including periodontitis model group, periodontitis and atherosclerosis compound model group, atherosclerosis model group and control group. Periodontitis model was initiated by ligating floss around teeth cervical and oral inoculating with Porphyromonas gingivalis (P.
