[The mechanism of the radioprotective action of sulfolane].

As a result of radiolysis of sulfolane, that has a radioprotective action, sulfonyl anion-radicals and hydrosulfonyl radicals are produced, subsequent transformations of which lead to complete regeneration of sulfolane. On the other hand, some other five-membered cyclic sulfones, that have no radioprotective action, are irreversibly depleted in reactions with water radiolysis products. Sulfolane is suggested to protect from the effect of e(-)aq and H.

[The possibility of using polarography for the diagnosis of radiation damage].

The polarographic method permitted to register changes in the protein higher structure at radiation doses of the order of tenths Gy. A technique is proposed and optimum conditions found for taking measurements in mammalian serum and plasma in vitro. It is suggested that the proposed technique, having been tested on experimental animals, might be used for an indirect diagnosis of radiation affection in human beings.
