Aim:
To establish a Friend murine leukemia virus (FLV)-induced immunodeficient BALB/C mouse model and investigate the effects of Fuzheng Paidu tablets on the body weight, thymus, spleen, and CD4+ and CD8+ T lymphocytes of FLV-infected mice. FLV was passaged twice in BALB/c mice. The infected mice were divided into six groups of ten mice based on their weights. The groups included the normal control group; virus control group; AZT group; high- (2.8 g/kg), medium- (1.4 g/kg), and low-dose (0.7 g/kg) Fuzheng Paidu tablet groups; and Fuzheng Paidu decoction (10 g/kg) group. The mice were administered Fuzheng Paidu tablets via gavage for 21 days. The body weight and changes in the thymus, spleen, and CD4+ and CD8+ T lymphocytes of each mouse were measured.
Results:
The splenic weight of the virus control group is significantly higher than that of the normal control group, with significant splenomegaly. In addition, the splenic inhibition indices of the AZT group and the high- and medium-dose Fuzheng Paidu tablet groups were approximately 93.80%, 37.80%, and 28.07%, respectively. Furthermore, the high and medium dose Fuzheng Paidu tablets could increase the thymus weights of the infected mice.
Conclusion:
Fuzheng Paidu tablets could inhibit splenomegaly, lower the splenic indices, and increase the thymic weights and thymic indices of FLV-induced immunodeficient mice.
