Figure 2From: Correlation of dynamic changes in γ-H2AX expression in peripheral blood lymphocytes from head and neck cancer patients with radiation-induced oral mucositisThe time-dependent accumulation of irradiation-induced γ-H2AX in PBLs in vitro. The γ-H2AX fluorescence was measured using a FACS-based assay in PBLs isolated from 15 patients mild OM (a) and 10 patients with severe OM (b) at 0, 0.5, 4, and 24 hours after in vitro exposure to 2 Gy of X-ray radiation. (c) The mean level of the relative fluorescence for patients with severe OM (diamonds) and mild OM (squares); *p <0.05.Back to article page
