Abstract

We investigated the in vitro effects of increasing concentrations (10-5-10-3M) of four muscle relaxants (succinylcholine, d-tubocurarine, vecuronium and atracurium) on histamine release (HR) from human peripheral blood basophils and mast cells isolated from lung parenchyma (HLMC) and skin tissues (HSMC). Basophils released less than 5% of their histamine content when incubated with any one of the muscle relaxants. In contrast, mast cells showed a marked heterogeneity in their response. Succinylcholine did not induce HR from any type of mast cell, and only high concentrations of d-tubocurarine (10-3M) caused HR from HSMC and HLMC. Vecuronium concentration-dependently induced HR from HLMC and HSMC. Atracurium concentration-dependently caused marked HR from HLMC and HSMC up to a maximum of 46.2±15.1% and 30.6±6.0%, respectively. From both HLMC and HSMC HR caused by atracurium and vecuronium was extremely rapid (t1/2
