Adaptive changes in the blood picture of sharptooth catfish in case of trecresan application when breeding in artificial environment
The work is devoted to the study of trecresan adaptogen effect on hematological parameters of sharptooth catfish bred in an artificial environment. In particular, the effect of trecresan on general hematological parameters and antioxidant system of African sharptooth catfish was assessed, since breeding in an artificial environment is accompanied by stress, in which oxidative processes increase, leading to damage of biological membranes and disruption of cell functioning. Blood samples were analyzed using an Axio Imager.M2 microscope (Carl Zeiss, Germany). The analysis of enzymatic activity (units / mg of protein) was carried out on a UV-1800 double-beam spectrophotometer (Shimadzu, Japan). The obtained results indicate that in case of trecresan adaptogen application, there was a tendency to a proportion increase of monocytes, platelets and stab neutrophils. There is an increase of the total amount of intracellular hemoglobin, superoxide dismutase and catalase activity in erythrocytes and in the blood offish bred with application of trecresan adaptogen. Trecresan induces production of interferons, increases the body immune status, activating cellular and humoral immunity, leads to a decrease of toxic products formed during lipid peroxidation by increasing the activity of enzyme unit in the antioxidant system and ensures antioxidant defense improvement of sharptooth catfish bred in an artificial environment. It strengthens the body immune system and increases resistance to adverse environmental factors. In our studies, trecresan revealed itself as a mild, effective immunomodulator.
