Australia antigen (AA)
6.Addition of IFN-γ to liquid culture of BMMNC including SCF, IL-3, GM-CSF and EPO cytokines showed significant stimulating effects on Fas antigen expression in AA, but not in normal controls, the expression in SAA was higher than that in CAA (P<0.05).
8.ABO blood group of 236 patients with aplastic anemia (AA) was compared with that of 2277 healthy individuals. Subjects with A antigen were susceptible to AA (R=1.3090, x~2=3.8489, P<0.05) .
