title: [Immunolocalization of hemeoxygenase-2 in neurons of the human vasomotor center in arterial hypertension].
abstract: We studied the immunolocalization of hemeoxygenase-2 in neurons of the medulla oblongata in men (n=8), aged 18-44 years, who died from causes unrelated to the injury of the central nervous system and in people with the lifetime diagnosis of hypertension (n=6). It has been found that neurons with enzyme positive reaction are present in all parts of the medulla oblongata with concentrations ranging from 0.5 to 13.7% of the total number of cells. The high proportion of small neurons with the high or moderate density of deposits was found in the sensory nuclei. Large cells of the motor nuclei often exhibit the negative or low intensity of the enzymatic reaction. In arterial hypertension, a decrease in the proportion AH NO-positive neurons and the average optical density of the reaction product was noted. The reduction was seen in most affected neurons in the rostral part of the solitary tract nucleus and the lateral reticular nucleus. In the motor nuclei and in the dorsal nucleus of the vagus nerve, these parameters decreased as well although the reduction was not as great as observed in the sensory nuclei.
