RESUMEN
The changes of immune function of red-cell C3b receptors in dog's blood exposured to 60Co Y-ray at various doses were observed by rosette rate of the red-cell C3b receptors to the sensitized yeast cells. Results showed that the function of the red-cell C3b receptors irradiated by 60Co Y-ray at doses of 1, 5 and 9 Gy was markedly lower than that of the control group, and that difference between all various dose groups is of tendency towards alinear relationship. It is possible that the C3b receptors are sensitive to radiation among elements of adult red-cells.
RESUMEN
Red cell immunologic adherent function and Se quantity were measured in 48 normal children of Keshan disease area and the reaction of red cell C3bR to these children. The results showed that the Se quantity and the rosette formation rate of red cell C3bR of normal children in Keshan disease area were significantly lower than that in the control(P0.05).
RESUMEN
The studies were undertaken on the trauma model of rats,whose right hind legs were amputated,in order to investigate the change in the immune adherence function of red cells,and the effect of treatment with Traditional Chinese Medicine,consisting of a mixture of Shen-er,to decrease immune adherence function of red cells after trauma.The results indicats that after trauma (1) the activity of C3b receptor of red cells decreased;(2) the amount of immune complexes on the surface of red cells increased;(3) the activity of the enhancing factors for the immune adherence of red cells dropped;(4) the activity of the inhibitors for the immune adherence of red cells elevated;(5) there is remarkable interrelation in the changes between the activity of the C3b receptors of red cells and the activity of the inhibitors for the immune adherence of red cells;(6) the mixture of Shen-er could effectively raise the inhibited activity of the C3b receptor of red cells;(7) the mixture could also effectively regulate the activity of the inhibitors of the immune adherence of red cells.
