ABSTRACT
Toad mast cells are degranulated by compound 48/80 and by chlorpromazine. The former was effective at rather high (100 micrograms/ml) and the latter at low (0.1 mM) concentrations. Toad mast cell degranulation induced by these drugs was characterized by cytoplasmic granule dissolution without cell lysis. The metabolic inhibitor, dinitrophenol, blocked the degranulation induced by both agents. Glucose reversed the inhibition of compound 48/80-induced degranulation. The results indicate that toad mast cell degranulation by compound 48/80 and by chlorpromazine is a non-lytic process.
