RESUMO
Objective: To study the effect of Bazhen decoction on red blood cell immunity in rats with Qi deficiency.Methods:After the rats were forced to swim for two weeks continuously, the rat model of Qi deficiency was established. Bazhen group and normal group were fed with Bazhen decoction (20g?kg -1 ,daily), and distilled water for fourteen days, respectively. The changes in red blood cell c 3b receptor rosette rate (RBC.c 3bRR) and red blood cell immune complexes rosette rate (RBC.ICRR) were studied while the influences of Bazhen decoction on above mentioned parameters were observed. Results: In Qi deficiency syndrome the levels of RBC.c 3bRR were markedly depressed, while RBC.ICRR markedly elevated. After feeding Bazhen decoction orally to rats model with Qi deficiency syndrome, the levels of RBC. c 3bRR were elevated, while RBC.ICRR depressed (compared with Qi deficiency model group, P
