Abstract：
OBJECTIVE:To investigate the effects of paeoniflorin, the main monomer component of Jinxueyuan granules, on the Ca2+ concentrations in salivary gland cells to further explore the salivation-promoting mechanism and effective monomer components of Jinxueyuan granules. METHODS:The salivary gland cells of suckling rats were cultured in vitro and loaded with a Fluo-3AM fluorescent probe, and changes in the intracellular Ca2+ concentrations were observed using a confocal laser scanning microscope. RESULTS:No significant changes in the intracellular Ca2+ concentrations were demonstrated (P>0.05) in the paeoniflorin-free Hank's media treatment group or in the higher-dose paeoniflorin (10-2 mol/L) Hank's media treatment group; however, a significant increase in the intracellular Ca2+ concentration in the lower-dose paeoniflorin (10-4 mol/L) treatment group was observed (P=0.001). Further study showed that treatment with the calcium channel blocker verapamil hydrochloride or with Ca2+-free D-Hank's media did not block the paeoniflorin-induced (10-4 mol/L) increase in intracellular Ca2+ (P<0.05). CONCLUSION:Paeoniflorin promotes the release of endogenous calcium to upregulate the intracellular Ca2+ concentration. Further studies should be performed to investigate the association between paeoniflorin and the Ca2+ concentration in salivary gland cells and to elucidate the corresponding functional pathways.
