摘要
Confocal laser scanning microscopy (CLSM) was applied to detect the intracellular [Ca2+] variety of fluorescent intension, with Fluo-3/AM fluorescence loaded in SFSMC. The results show that 10 μmol/L Lacidipine can reduce the frequence which 10 μmol/L 5-HT induced [Ca2+] spark in SFSMC of calcium over loading to 50%, and amplitude to 50% or so. We can draw a conclusion that dihydropyridines cal-cium antagonists lacidipine can antagonize the release of intracellular [Ca2+] which 5-HT-induced in dose dependent manner.
