title: [Immunocytochemical characterization H2S-positive neurons in the nuclei of bulbar cardiovascular center in the development of renovascular hypertension].
abstract: Immunocytochemical method in Wistar rats in 6 nuclei of the medulla oblongata, related to the cardiovascular center, identified nerve cells (H2S-neurons) with a positive reaction to cystathionine beta-synthase (CBS)--an enzyme involved in the synthesis of hydrogen sulfide in the brain. Found that in rats with renovascular hypertension only after 6 weeks of hypertension in the neurons of the reticular nuclei observed a significant reduction of CBS, while the number of H2S-positive cells in this period does not change significantly. Only at week 12 renovascular hypertension notes marked reduction in the proportion of positive H2S-neurons in the reticular nuclei of most of the medial zone, although further reduction in the intensity of the enzymatic reaction in the neurons were observed. Between 14-16 weeks of hypertension to further reduce the proportion of neurons and H2S-content of the enzyme is not observed. In a single nucleus and reticular lateral nucleus, which receive afferent impulses in the development of renovascular hypertension specify the minimum change of the indicators.
