Effects of Recombinant Human Erythropoietin on Immune Function of Chemotherapy Mice / 实用儿科临床杂志

ABSTRACT

Objective To observe the effects of recombinant human erythropoietin(rh-EPO) on immune function of cyclophosphamide-treated mice.Methods Six-week-old mice were randomly divided into 4 groups.Cyclophosphamide plus normal saline group(CTX(+NS));cyclophosphamide plus lower and higher dosage rh-EPO group(CTX+LDrh-EPO and CTX+HD rh-EPO);normal saline control group(NS).The changes of Hb,WBC,red blood cell immune function((C_3b)-R%),T lymphocyte proliferative responsiveness optical density index A(A score),IL-2,TNF-? of 4 groups were observed.Results The CTX + NS group showed lower levels on Hb,WBC,C_(3b)-R%,A score,IL-2 and TNF-? compared with NS normal control group(P0.05).There were positive correlation between C_(3b)-R% and Ascore,C_(3b)-R% and IL-2.Conclusions 1.Cyclophosphamide treated mice have lower Hb,WBC,C_(3b)-R%,A,IL-2 and TNF-? secretion.2.rh-EPO administration have improvements with Hb,RBC immune function,T lymphocyte proliferative responsiveness and IL2 production.
