A comparative analysis is performed between the oxidoreductase activity (malate and lactate dehydrogenase: MDH, LDH) in the gills (the lamellae of first gill arch) and brain structures (medulla oblongata, middle brain, forebrain, and diencephalon) of Scorpaena porcus L, 1758 under short-term separated exposure to hypoxia (90 min, 1.7–3.7 mg О 2 /L and 0.3–1.0 mg О 2 /L) and hydrogen sulfide (5 min, 37 µМ and 74 µМ Na 2 S). Under experimental conditions, the increase in hypoxic and hydrogen sulfide loading promotes an increase in the interaction in the MDH ↔ LDH activity system in the tissues under study: the highest value of the correlation coefficient is found in the gills (r = 0.87, p < 0.05) and medulla oblongata (r = 0.96, p < 0.01) This paper further considers the functional relationship between the oxidoreductase activities in the tissues and discusses the metabolic effects of hypoxic and H 2 S loading on the activity of oxidoreductases and the possible mechanisms of the effects.
