Abstrakt: Intravenous administration of clofelin blocks transudation of 131I-albumin into the dura mater of rats in electrical stimulation of the trigeminal ganglion. Preliminary injection of the alpha-adrenoblocker yohimbine and the antagonist of serotonin receptors 5-NT1 mianserin completely removes the blocking effect of clofelin. Naloxon and the alpha 1-adrenoblocker prazosin had no effect on the degree of expression of albumin transudation and the clophelin effect. The role of the adrenergic system, the presynaptic alpha 2-adrenoceptors in particular, in functioning of the trigeminovascular system and the development of neurogenic inflammation in the dura mater is discussed.
