Abstract:
Objective To investigate the toxic effect of cadmium (Cd) on the ultrastructure ,expression of related protein and the signal molecule phosphrylated P38 mitogen-actived protein kinase(P-P38MAPK) of primary cultured rat sertoli cell(Sc) ,and the protective effect of astragaloside (A ) on it .Methods The primary cultured rat Sc were divided into the control group ,Cd (50 mol/L)group and Cd(50 mol/L) plus A(10 mg/L) group ,they were used for the electron microscope observation and the im-munohistochemistry detection of vimentin ,E-cadherin ,-catenin and P-P38MAPK .Results The Sc ultrastructural changes included that the swelled mitochondria ,abundant lipid droplets and dilated endoplasmic reticulum were found in the Cd group .Further ,apop-tosis occurred in some Sc .However these ultrastructure changes above mentioned were slighter in the Cd plus A group ;the immu-nohistochemistry showed that the positive products of vimentin ,E-cadherin and-catenin were obviously decreased in the Cd group (P<0 .05) ,and those in the Cd plus A group were higher compared with the Cd group(P<0 .05);the expression of P-P38MAPK in cytoplasm was increased in the Cd group ,and showed the trend to move from cytoplasm to nucleus ,meanwhile ,the positive prod-ucts expression in the Cd plus A group was lower than that in the Cd group (P<0 .05) .Conclusion Cadmium can cause the injury of the Sc ultrastructure ,damage of cytoskeletal protein and fibronectin ,and increase of P-P38MAPK level ;astragaloside can antago-nize the toxicity of cadmium on Sc ,the protective effect maybe related with the decrease of P-P38MAPK in Sc .
