Figure 5From: Ex vivo effects of flavonoïds extracted from Artemisia herba alba on cytokines and nitric oxide production in Algerian patients with Adamantiades-Behçet's diseaseEffect of flavonoïds extract on IL-4 (pg/mL) production in PBMC of ABD patients ( n = 20). Cells (5 × 106 cells/mL) were treated with different concentrations (5, 10,20,30,40 and 50 μg/mL) of flavonoïds during 20 h. Presence of cytokines in supernatants were measured by ELISA test. Results are mean ± SD of seven separate experiments performed in triplicate. *p < 0.05 IL-4 levels were significantly different from the control value.Back to article page
