Pharmacological exploration of the central nervous system carried out by means of a series of tests confirms the affinity of 3-(2,2-dibromovinyl)-2,2-dimethylcyclopropanecarboxylic acid alpha-cyano-3-phenoxybenzyl ester (delta-methrin) for the nervous system and reveals the following activities of deltamethrin: Deltamethrin has no neuroleptic or sedative(More)
The experiments carried out on the isolated carotid sinus in the rabbit demonstrated that alpha and beta adrenoceptors are capable of detecting the circulating catecholamines and the catecholamines of the synaptic cleft in order to modulate the release of noradrenaline from the sympathetic nerve endings in response to a potential action.
The experiments carried out showed the presence- in sympathetic nerve endings ot the carotid sinus- of alpha and beta adrenoceptors which by means of respective negative and positive feedback processes, modulated NA release induced by a sympathetic nerve stimulation. Similarly, Pgs acted by means of a negative feedback mechanism to regulated adrenergic(More)
