[The effect of irradiation on dopamine level and metabolism in the rat brain]

In experiments on rats it was shown that after 20 Gy irradiation dopamine and homovanilic acid content increases in the caudate nucleus and limbic structures of the forebrain: dopamine disappears more readily when its biosynthesis is blocked. The rate of the mediator degradation in the brain increases by 1.5-2 times, and the rate of the synthesis, by 3-5 times at early times after irradiation.
