Thermal Phenomena in Erythrocytes of the Black Sea Thornback Ray (Raja clavata L.) and Black Scorpionfish (Scorpaena porcus L.) In Vitro

An evolutionary development of the rheological characteristics blood in capillary flow is one indicator fishes’ adaptation for changing temperature conditions. Our earlier studies showed that large, nucleated erythrocytes Black Sea thornback ray (Raja clavata L.) and scorpionfish (Scorpaena porcus had high ecto-ATPase activity. This activity varied from 3.0 to 3.9 6.0 10.0 nmol Fn/min/µL RBC rays scorpionfish, respectively. The use thermal energy ATP hydrolysis process made by ecto-ATPases fish provided a heating plasma cells’ membrane near-wall layer with an aim improve flow. To confirm proposed assumption, we studied phenomena suspensions fishes continuous recording changes experimental cell suspension addition (1 mg/mL) vitro. A higher “thermal” was established comparison ray, which multiplicity membranes fishes. presence heat-producing evidence possible erythrocytes, both maintain functional state red cells section
