The application of the determination of activity of red blood cell C3B receptor in observation of radiation effects

The activity of red blood cell C3B receptor has been determined in the cases of 101 healthy persons, 42 chest fluoroscopies (healthy blood donors) and 30 G.I. examination (non-cancer patients) before and after exposure, respectively. The results showed that the rate of immune adherence is 17.2 +- 2.8% in normal control group, 16.2 +- 2.4% and 12.4 +- 1.2% in chest fluoroscopies group (mean exposure doses of surface of body 1.59 R) and 16.4 +- 2.6% and 13.3 +- 1.7% in G.I. examination group (mean exposure doses of surface of body 7.28 R) before and after exposure respectively. All of the exposure groups showed significant changes (P < 0.001) compared with the normal control group and that before examination
