RESUMO

Objective To study systemic hematogenic immunoreactions induced by bacterial infections using simulation of natural system.Methods Whole blood 0.2 mL or white blood cells 0.2 mL and plasma(or normal saline)0.3 mL were stimulated by 0.2 mL of yeast and inactivated Bacillus Calmette-Guerin(BCG,5?10~8/mL),respectively,which were incubated at 37℃for 1 h. Interleukin(IL)-8,C3,C4 and chemokine receptor Fy6 were detected by flow cytometry(FCM)and en- zyme-linked immunosorbentassay(ELISA).Results Bacteria could activate red blood cell to modulate IL-8 release from white blood cells in plasma.In nature experimental group,activation rate(37.04?34.84)of IL-8 was significantly higher than that(1.09?0.77)in isolation experimental group.In nature experimen- tal group,value increment(0.01?0.01)of complement C4 was significantly higher than that(-0.0027?0.008)of isolation experimental group(P
