EFFECTS OF COMPOUND FACTORS OF SIMULATED WEIGHTLESSNESS (HDT-30°) AND NOISE ON THE NEUROENDOCRINE-IMMUNITY SYSTEM IN RATS

The results of the experiment show that the rats exposed to the suspension(HDT--30°) and the noise environment of 85 dB(A) for 10 days has a significantdecrease in lympocyte blastogenesis and interleukin--2 (IL2), a significant increase inthe content of plasma corticosterone, a tendency to be raised in the content of dopamine (DA) and noradrenaline (NA) in hypothalamus. These changes may be incoherence with stress alarm reaction. The indices mentioned above in the 85 dB(A)show a similar changes, but are less significant than that of the group which exposed to the noise and suspension. The function disturbance of the causes which makeastronauts suffering from infection diseases in space.
