title: [NO and H2S brain systems of the Japanese shore crab Hemigrapsus sanguineus under conditions of anoxia].
abstract: The topography and dynamics of the activity of the enzymes of the synthesis of nitric oxide (NO) and hydrogen sulfide (H2S) in the brain of the Japanese shore crab Hemigrapsus sanguineus after 1, 6, and 12 h ofanoxia was studied histochemically and immunocytochemically. Changes in the activity and number of NO- and CBS-immune-positive cells that take place due to anoxia and the intensity of which depends on the duration of the influence were revealed. The fact that the balance between the nitric oxide and hydrogen sulfide systems in the brain of the crabs H. sanguineus is preserved indicates the joint participation of those systems in the central regulation of adaptive mechanisms under the influence of anoxia and, apparently, plays an important role in the adaptation of these hydrobionts to oxygen deficit.
