RESUMO
OBJECTIVE@#To observe the expression of Bcl-2 and Bax proteins in rat's myocardial cells after Macleaya cordata alkaloids poisoning, and to provide certain molecular biology references for the detection of Macleaya cordata alkaloids poisoning.@*METHODS@#Experimental model of Macleaya cordata alkaloids poisoning was established, the expression levels of Bcl-2 and Bax proteins in these cells were detected by immunohistochemistry, and the results were analyzed by computer image system.@*RESULTS@#The expression levels of Bcl-2 and Bax proteins in myocardial cells in poisoning groups were much greater than those in the control groups (P<0.05).@*CONCLUSION@#If the clinical symptoms may not be obvious, the detection of Bcl-2 and Bax proteins level by immunohistochemistry still could be ancillary method.
