title: The effect of alkylating agents on the synaptic transmission in the frog's isolated sympathetic ganglion.
abstract: The effect of four alkylating agents, such as dibenamine, phenoxybenzamine, mannomustine and cyclophosphamide, was studied on the isolated sympathetic ganglion of the frog. It has been established that all of these agents were able to bind to the nicotinic receptors through the formation of the reactive ethylenimonium ion not only in the frog ganglion but also in the motor end-plate of the rat skeletal muscle. The binding to the ganglionic receptors showed reversible and irreversible phases being dependent not only on the drug concentrations and the incubation time used but the temperature of the medium as well.
