Assessment of phagocytic activity of tilapia blood cells under hormone-induced stress

The paper presents an assessment of the phagocytic ability of blood cells of Nile tilapia Oreochromis niloticus L. under the hormonal induction of stress with range of duration. It has been revealed that Staphylococcus aureus is phagocytosed by leukocytes, platelets, and erythrocytes of tilapia blood in direct smears. The phagocytic capacity of the cells has been quantified.

Prevention of embryonic mortality in recipient cows

The results of research on the prevention of fetal mortality in recipient cows using a combination of anesthetic and sedative agents to relieve the stress response conducting embryo transplantation are presented. It is noted that during sacral anesthesia with 2% novocaine solution and intramuscular administration of 0.5 ml/ 100 kg of xylanite solution before embryo transplantation, the physiological parameters were within the limits of the physiological norm.

Blood fibrinogen dynamics in fish under stress

The paper presents the research results of blood fibrinogen in carps under stress. It is established that the coagulation processes have accelerated under hypoxic stress by the 4th day of the experiment.
