Abstract: The effect of combined administration of adrenaline (0.4 mg/kg, i.p.) and b1-blocker metoprolol (25 mg/kg) on the activity of glutathione peroxidase (GPO), glutathione reductase (GR), catalase, adenosine deaminase (AD), AMP deaminase (AMPD), 5¢-nucleotidase (5¢N), on the level ofmalonic dialdehyde (MDA) and conjugated dienes (CD) was investigated. In blood adrenaline administration to animals caused an increase in the activity of AMPD, AD, 5¢N and GPO, and the increase the level of CD in the blood increases. Metoprolol caused a more pronounced increase in the activity of blood AMPD, AD, 5'N and the amount of CD. In contrast to adrenaline, metoprolol decreased the MDA level of, and decreased the activity of GPO and catalase. Combined administration of metoprolol and adrenaline to animals was accompanied by an increase in the activity of AD, AMPD, 5¢N, a decrease in the activity of GR, GPO, catalase, and a decrease in MDA in the blood. In the heart, adrenaline injection was accompanied by an increase in the MDA level, a decrease in 5¢N activity and an increase in the ratio of the activities of the enzymes AD+AMPD/5¢N. Metoprolol injection reduced MDA and CD levels and the activity of GR and GPO. The combined administration of metoprolol and adrenaline in the heart was accompanied by activation of AD, AMPD and 5¢N, and a decrease in the amount of MDA and CD, and a decrease in the activity of GR, GPO, and catalase. In the liver adrenaline caused an increase in MDA and DC levels, activation of catalase, AD, AMPD, and 5¢N. Metoprolol caused a decrease in MDA and CD levels and activity of catalase and GPO, an increase in the activity of AD and AMPD in the liver. Combined administration of adrenaline and metoprolol reduced manifestations of the heart and liver oxidative stress response as compared with administration of adrenaline alone.
