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 effects of 2-(2 dimethylaminoethyl) 5-benzylidene 6-methyl (2H,4H)-3-pyridazinone (III) were studied on the biosynthesis of TXA2 and PGI2 in vitro the TXA2 and PGI2 synthetase activity of heart tissue. Biosyntheses of TXA2 and PGI2 were carried out using arachidonic acid as a substrate and horse platelet and aorta microsomes as sources of TXA2 and PGI2… (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.
As an experimental model, we used 6-week-old genetically obese-hypertensive rats (SHR-fa/fa) which were obtained by transferring the fatty/fa gene of hyperlipaemic obese rats into the genome of the SHR strain: the SHR-fa/fa were bigger and more hypertensive than their SHR littermates. Studying the capacity of the hearts, kidneys, spleens, brains and lungs… (More)
