Description
The changes were studied in the levels of catecholamines and L-DOPA in the pituitary gland of sheep after all-body irradiation with 60Co at the total dose of 6.7 Gy for seven days. The power input per hour of irradiation source was 0.039 Gy. The catecholamines were determined after having been isolated from the tissues and determined by the method of spectral fluorimetry. After all-body exposition to gamma-radiation L-DOPA dropped in pituitary gland in comparison with the control group of sheep most significantly by 66.7% (P < 0,001). A similar drop like in the case of adrenaline was also observed in epinephrine (P < 0,05). On basis of the results we presume that the all-body irradiation of sheep by results a significant decrease in the content of catecholamines in pituitary gland, which is probably in relation with failure of synthesis and degradation of catecholamines and with total organism injury.
