Fig. 4From: Quick and improved immune responses to inactivated H9N2 avian influenza vaccine by purified active fraction of Albizia julibrissin saponinsEffect of AJSAF on Con-, LPS-, and H9–Ag-stimulated splenocyte proliferation in the immunized mice. Splenocyte proliferation was measured by the MTT method and shown as a stimulation index (SI). The values are presented as means ± SD (n = 6). Significant differences with IH9V alone group were designated as *P < 0.05, †P < 0.01, and ‡P < 0.001; those with CH9V group as §P < 0.05, #P < 0.01, and ¶P < 0.001Back to article page
