RESUMEN
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.

OBJECTIVE@#To observe pathological changes and apoptosis in rats myocardial cells after Macleaya cordata total alkaloids poisoning, and to provide some references for Macleaya cordata total alkaloids poisoning detection.@*METHODS@#An experimental model of Macleaya cordata total alkaloids poisoning was established, and the technology of TUNEL staining was used.The results were analyzed by computer image analysis competitive system.@*RESULTS@#Quantities of apoptosis in myocardial cells in poisoning groups were much more than those in the control groups at different tages (P<0.01). In addition the quantities of apoptosis were different after different poisoning duration.@*CONCLUSION@#Although clinical symptoms was not obvious and could not be detected by poison analysis. Pathological changes induced by Macleaya cordata total alkaloids could be found through the apoptosis detection.
