TURMERIC EXTRACT IN CORRECTION OF NERVOUS AND IMMUNE SYSTEMS FUNCTIONAL ACTIVITY PARAMETERS IN EXPERIMENTAL ALCOHOLISM

Full Text

Introduction. Prolonged alcohol consumption affects the immune and nervous systems, causing a breakdown in their functional connections [1]. Considering the neuroprotective and immunotropic properties of rhizomes polyphenolic compounds of the plant Curcuma Longa L. (turmeric) [2-5], the purpose of this work was to study the effect of turmeric extract on behavior parameters and the severity of the cellular immune response in animals with experimental alcoholism. Material and methods. The experiments were performed on male mice (CBAxC57BL/6)F1 (n = 60), healthy and in a state of experimental alcoholism, formed by the method of 6-month soldering with a 10% ethanol solution. Turmeric powder (Supplier Test Report No. 561-374-1-16 / BM dated June 09, 2016) was dried ground turmeric (Mumbai, India). The solution of turmeric was a 15-day extract of dry powder in 40% ethanol (150 g/l). Control groups: healthy mice and alcoholic animals, received water or 10% ethanol solution, 5 ml per animal per day. Animals of the experimental group took turmeric extract with a final ethanol concentration of 10%, in the same volume, daily, for 2.5 months, then all animals were evaluated for behavior parameters in the “open field” test and the severity of the cellular immune response by the intensity of the development of a delayed-type hypersensitivity reaction (DTH), according to the methods described earlier [6, 7]. Statistical processing of the results was performed using the Statistica 7.0 software package (StatSoft, USA) using the non-parametric Mann-Whitney test. Data are presented as M ± SD. Differences were considered statistically significant at p < 0.05. Results and discussion. In experimental alcoholism, suppression of the motor and research components of animal behavior was recorded, as evidenced by a decrease in the parameters of motor activity: horizontal (peripheral from 88.4 ± 16.2 to 22.7 ± 4.2, p < 0.05; central from 7.1 ± 1.7 to 0.1 ± 0.1, p < 0.05) and vertical (free from 1.3 ± 0.1 to 0.3 ± 0.1, p < 0.05; supported on the wall from 2.9 ± 0.5 to 1.1 ± 0.2, p < 0.05) in comparison with the group of healthy animals of the corresponding age. In alcoholic mice treated with turmeric extract, behavioral stimulation was recorded compared to animals treated with ethanol solution (horizontal: peripheral from 22.7 ± 4.2 to 54.2 ± 5.2, p < 0.05; central 0.1 ± 0.1 to 4.1 ± 0.2, p < 0.05; vertical, wall-supported from 1.1 ± 0.2 to 2.3 ± 0.1, p < 0.05). When assessing the severity of the DTH reaction after taking the extract of turmeric, the results presented in table 1 were obtained. Consequently, the use of turmeric extract on the background of taking ethanol solution in alcoholic animals led to the stimulation of open field behavior and an increase in the cellular immune response to the level of healthy animals of appropriate age, which testifies to the protective effect of turmeric on a number of parameters of the functional activity of the nervous and immune systems during chronic ethanol intoxication.
