RESUMO
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.
