摘要:

背景:课题组前期实验证实中药复方消可宁能有效防治早期糖尿病肾病。
目的:比较大黄酸与大黄素对高糖培养的大鼠肾小球系膜细胞凋亡的影响程度。
方法:分别用不同浓度20,40,80 µmol/L的大黄酸和大黄素刺激高糖培养的肾小球系膜细胞,苏木精-伊红染色观察凋亡细胞形态,DAPI荧光染色观察细胞核凋亡情况,流式细胞仪观察细胞凋亡率。
结果与结论:苏木精-伊红染色及DAPI染色结果显示大黄酸对髙糖培养的肾小球系膜细胞凋亡的影响程度强于大黄素的影响程度。细胞凋亡率的对比显示大黄酸对髙糖培养的肾小球系膜细胞的早期凋亡率与晚期凋亡率均强于大黄素。说明低中高浓度的大黄酸、大黄素均可诱导肾小球系膜细胞凋亡,但大黄酸的药效强于大黄素。

Abstract:

BACKGROUND: Our previous study has already manifested that Chinese medicine Xiaokening can effectively prevent and treat the early diabetic nephropathy.
OBJECTIVE: To compare the effect of rhein and archen on the apoptosis of mesangial cells of rats cultured with high glucose.
METHODS: Mesangial cells were stimulated by different concentrations of rhein and archen (20, 40 and 80 µmol/L). Morphology of apoptotic cells was observed by hematoxylin-eosin staining. Karyon apoptosis was examined by fluorescence staining of DAPI. Cell apoptosis rate was detected by flow cytometry.
RESULTS AND CONCLUSION: The outcome of hematoxylin-eosin staining and DAPI staining indicated that the effect of rhein was much stronger than that of archen on the apoptosis of mesangial cells in the rats cultured with high glucose. Comparison of the apoptosis rate also indicated that the rhein had a stronger effect on the earlier and the later stage apoptotic rate of mesangial cells than archen. Both rhein and archen with different concentrations can induce apoptosis of mesangial cells, but the effect of rhein is much stronger.
