ABSTRACT
Objective To study the expression of membrane glucocorticoid receptors(mGR), the correlation between mGR and glucocorticoid(GC)'s effects on apoptosis and proliferation of peripheral blood lymphocytes(PBLs) in minimal change nephrotic syn-drome(MCNS)and the influence of GC on mGR. Methods MCNS, nonminimal change NS(NMCNS) and healthy children were involved in this study. Indirect immune fluorescence and flow cytometry were used to examine the percentages of positive mGR lymphocytes; the apoptosis of PBLs was measured by propidium iodide(PI) staining and the proliferation of PBLs was investigated by fa -TdR incorporation. Results 1.mGR expression in MCNS was higher than that in NMCNS and healthy control,but it was reduced after clinical GC therapy(P
ABSTRACT
Objective To explore the apoptosis and proliferation of peripheral blood lymphocytes(PBLs) from primary nephrotic syndrome(PNS) and effects of dexamethasone(Dex) on them.Methods Minimal change NS(MCNS), non-minimal change NS(NMCNS) and healthy children were involved in this study. PBLs were cultured in vitro with Dex or PHA+Dex or without PHA and Dex. Apoptosis of PBLs was measured by propidium iodide(PI) staining; The effects of Dex at different concentrons on PBLs′proliferation were investigated by 3H-TdR incorporation.Results The apoptotic rate of vacuity group in MCNS was lower compared with NMCNS and healthy controls(P
