Abstract: ? In the present study, the in vivo effect of Ge 132 on NK cell activity and red cell immune function in tumor bearing mice was observed. The results showed that Ge 132 could significantly inhibit the growth of the tumor in the tumor bearing mice. the activity of NK cells and the levels of RBC C 3b receptor rosette forming rate(RBC C 3bRR) and RBC tumor rosette forming rate(RBC TR) in tumor bearing mice were significantly lower than those in normal control group ( P <0.01). However, the RBC immune complex rosette forming rate(RBC ICR) was higher in tumor bearing mice than that in normal control group ( P <0.01). Ge 132 could enhance NK activity and increase RC 3bRR and RBC TR and decrease RICR of tumor bearing mice compared with tumor control group. The results indicated that Ge 132 could significantly enhance the activity of NK cells and the red cell immune function in tumor bearing mice. The anti cancer effect of Ge 132 may be mediated by regulating the immune functions in tumor subjects.
