ABSTRACT
OBJECTIVE@#To observe the effects of heroin on intracellular free Ca2+ in rat myocardium.@*METHODS@#The effects of heroin on intracellular free Ca2+ were observed in cultured neonatal rat myocardium by measuring intracellular free Ca2+ concentration using calcium fluorescent probe Flou-3/AM and laser scanning confocal microscope.@*RESULTS@#Different doses and concentrations of heroin appeared to have different effects on intracellular free Ca2+ concentrations, with a dosage dependent short linear increase in the fluorescence intensity (i.e., Ca2+ concentration) leading to [Ca2+]i peak.@*CONCLUSION@#Heroin could affect concentrations of [Ca2+]i in myocardium and its dosage related effect needs further investigation.
