ADRENO- AND CHOLINOREACTIVITY OF ERYTHROCYTES AND ESTIMATION OF THEIR CONJUGATION WITH PARAMETERS OF FREE RADICAL BALANCE OF BLOOD IN NON-LINEAR RATS
The values of the β-adrenoreactivity of erythrocytes (β-ARE, 40.6 ± 2.3 rel. units) and the M-cholinoreactivity of erythrocytes (M-ChRE, 7.9 ± 0.3 rel. units), concentration of hemoglobin, the parameters of free radical balance: the level of TBA-reactive products (TBA-RP) and catalase activity in erythrocytes and plasma were determined in male non-linear rats. Sample grouping by clustering largest β-ARE showed that rats with a high β-ARE (>50 rel. units) have a greater concentration of hemoglobin, TBA-RP and CAT in erythrocytes, than rats with an average (30 to 50 rel. units) and low (<30 rel. units) β-ARE. According to the results of the correlation and factor analysis, M-ChRE is predominantly conjugated with erythrocyte (Factor 1), and β-ARE – with plasma characteristics of free radical balance in blood (Factor 3). The introduction of β-adrenergic blocker anapriline (2 mg/kg bw) decreases β-ARE and potentiates the accumulation of TBA-RP in the erythrocytes and plasma, the administration of the blocker of M-cholinergic receptors atropine (1 mg/kg bw) reduces not only M-ChRE, but also β-ARE and promotes the growth of erythrocyte catalase activity. Thus, in the intact state, under the conditions of blockade of adrenergic receptor and cholinergic receptors, dependences have been revealed that make it possible to treat β-ARE and M-ChRE as a link between regulatory influences on erythrocytes and biochemical, including free radical processes in the «erythrocyte – blood plasma».
