[The effect of gamma-irradiation on the level of circulating immune complexes in rat blood].
During the first 10-20 min after gamma-irradiation (75 Gy) of rat head in the cranio-caudal direction a drastic 2-3-fold decrease was observed in the level of circulating immune complexes (CIC) in the blood. CIC content of the blood was restored 60 min after irradiation, and no changes occurred during the following 5-hour period of observation.
