Effects of gypenosides on cellular immunity of gamma-ray-irradiated mice
Objective:
To investigate the effects of gypenosides (Gs) on cellular immunocompetence in the gamma-ray-irradiated mice.
Materials And Methods:
Tested mice of ICR strain were treated continuously with Gs for 10 days before or after 4 Gy gamma-irradiation. Body weight and splenic weight of mice were measured. The blastogenic response of splenocytes to mitogens, such as PHA, Con A and LPS were also detected. The cellular immunocompetence was measured by 3H-thymidine incorporation in each tested mouse.
Results:
Body weight as well as splenic weight decreased in gamma-ray-irradiated mice. The blastogenic responses of splenocytes to mitogens were inhibited after gamma-ray irradiation. To treat with Gs was effective to enhance the recovery of body weight, splenic weight and immunocompetence in gamma-ray-irradiated mice from radiation damage.
Conclusions:
Four Gy gamma-ray irradiation could decrease splenic weight and cellular immunocompetence of mice. Gs could help the recovery of the splenic weight and cellular immunocompetence in gamma-ray-irradiated mice.
