title: [Effect of dibucaine and lidocaine on histamine release from mouse bone marrow-derived cultured mast cells].
abstract: We examined the effects of dibucaine and lidocaine on histamine release from mouse bone marrow-derived cultured mast cells. The effects of these drugs on intracellular calcium were also monitored by assessing Fura-2 signals. Additionally, the inhibitory effects of lidocaine on IgE dependent and independent stimuli were examined. Though dibucaine induced histamine release and increases in intracellular calcium from mast cells dose-dependently, lidocaine did not. Lidocaine inhibited both the IgE-dependent and independent histamine release from mast cells in a dose dependent manner. However, the ability of lidocaine to inhibit the IgE-dependent response was greater. Lidocaine also inhibited increases in intracellular calcium to a greater extent after IgE-dependent stimulation as compared with IgE-independent stimulation. The degree of the inhibition of histamine release by lidocaine appeared to parallel decreases in calcium mobilization.
