ABSTRACT
BACKGROUND:Primary culture of glomerular mesangial cells was less achievement ratio,short survival time,and less passage times.In particular,extraction of renal glomerulus remains difficult for culturing highly pure mesangial cell OBJECTIVE:To establish a more simple.high successful rate and good reproducibility method of human mesangial cells in primary cultureMETHODS:Kidneys jsolated from induction of labor with water bag voluntary were cut into pieces.and human mesangial cells were cultured with eugenic selection methods.Morphology was observed using inverted phase contrast microscope and transmission electron microscope,cell phenotype was detected using immunohistochemical method,and vimentin expression was observed using laser scanning confocal microscope.RESULTS AND CONCLUSION:The cultured mesangial cells were fusiform-shaped,irregular star-shaped,and slender.Organelle was rich in cytoplasm,cell process was clear,and microvillus was observed on the cell membrane.The cells expressed a-actin,myosin,vimentin,desmin but not expressed cytokeratin and Ⅷ factor.Laser scanning confocal microscope demonstrated that vimentin expression was positive and had the characteristics of fiber bundles.This suggested that the cultured intercapillary cells were coincidence with the characteristics of mesangial cell The renal corticaI tissue combined eugenic selection method was a simple and efficient method to culture human mesangial cells.
ABSTRACT
The 34 cases in the treatment group were treated with allicin injection through Murphy drip for a course of 10 days with nitroglycerin group as control. Results demonstrated that the total effective rate for symptoms and ECG were 82% and 62% respectively for the treatment group. It also markedly lowered the level of plasmal endothelin, and that of blood sugar in diabetics'. Adverst effects included local pain at the injection site and headache, the incidence of which were 18% and 6% respectively. This therapy is a satisfactory one for stubborn angina pectors.
ABSTRACT
Objective To explore the molecular and cellular mechanism of Zaohuang Capsule No.3 (ZHC3) in treating chronic renal failure through observing the effect of ZHC3 on the human glomerular mesangial cells (GMC). Methods The proliferation of human GMC fostered in ZHC3 was detected by MTT, and the fibronectin (FN), interleukin 6 (IL-6) and transforming growth factor ?1 (TGF-?1) secretion was detected by ELISA. Results ZHC3 significantly inhibited GMC proliferation (P
