人参皂苷Rg1、Rb1对体外培养膝软骨细胞凋亡的影响

目的观察人参皂苷Rg1、Rb1对体外培养软骨细胞,IL-1诱导软骨细胞凋亡的影响,并比较其对细胞影响的差异性。方法成功培养出软骨细胞后,进行人参皂苷影响细胞代谢浓度筛选,设人参皂苷Rg1不同浓度组、人参皂苷Rb1不同浓度组,MTT法检测人参皂苷对软骨细胞代谢的影响,选取其Rg1、Rb1合适浓度作为干预细胞凋亡浓度组,设立人参皂苷Rg1、Rb1组和对照组,IL-1诱导软骨细胞凋亡,流式细胞仪检测其凋亡数量和比例,透射电镜检测细胞凋亡形态和亚微结构。结果人参皂苷Rg1m、Rb1m组对软骨细胞调亡有明显的抑制作用,在抑制软骨细胞过度凋亡无明显差异。结论人参皂苷Rg1、Rb1能明显抑制软骨细胞过度的调亡,抑制膝骨性关节炎的发生、发展,为进一步在体实验提供理论基础。

Impacts of Ginsenosides Rg1 and Rb1 on Apoptosis of Knee Chondrocyte Cultivated in Vitro

Objective To observe the impacts of ginsenoside Rg1 and Rb1 on chondrocyte cultivated in vitro and chondrocyte apoptosis induced by IL-1,and compare the differences of them in the impacts on cells.Methods After the successful culture of chondrocytes,ginsenosides were used to impact the concentrations of cell metabolism.The screening was performed.Ginsenoside Rg1 and Rb1groups of different concentrations were established respectively.MTT was adopted to determine the impacts of ginsenosides on chondrocyte met...
