[Role of opiate peptides in regulation of the lymphocyte proliferative activity in patients with dyscirculatory encephalopathy in the late period after irradiation].
The authors have studied the endorphins effects on lymphocyte proliferation of 55 Chernobyl male workers aged 36-69 yrs and exposed to radiation dosed from 0.25 to 3.8 Sv. These patients have been found to have discirculatory encephalopathy in comparison with 30 non-exposed workers and 25 healthy volunteers. Physiological concentrations of alpha- and beta-endorphins intensify the spontaneous and mitogen-dependent proliferation of T-lymphocytes. Intensifying effect of the opiate peptides is being blocked by naloxone. Obtained data demonstrate the unidirectional opiates action, however the beta-endorphine effect dominates. The detected effect of endorhines are shown both among exposed to ionizing radiation and non-exposed. The irradiation higher than 1 Sv results in disturbance of the endorphine reception by T-cells with blockage of the influence of naloxone. It confirms the presence of radiation effects in opiate regulation of the lymphocyte proliferation.
