Investigations on the effects of vibration on the neurosecretory cerebral system using 3-H-methionine.

The effects of vibration on the neurosecretory system of the brain were studied using the method of autoradiography. Both control and exposed to vibration (for 6 or 12 days) guinea pigs were injected with tritiated methionine and the uptake of the isotope was determined after 1, 6, 12, 24 h. Some differences were found in the number of silver grains in the brain neurosecretory system between the controls and both experimental groups. These differences, were however, not statistically significant.
