Changes in the metabolism of axillary lymph node cells as a predictor of regional metastasis in breast cancer

Figure 2 Kinetics of delayed fluorescence in a lymph node stained with erythrosine. A: Kinetics of delayed fluorescence in a lymph node stained with erythrosine under multi-pulse excitation at a frequency of 10 Hz (curves for the first and tenth excitation pulses are shown); B: Kinetics of phosphorescence in a lymph node stained with erythrosine under multi-pulse excitation at a frequency of 10 Hz (curves for the first and tenth excitation pulses are shown); C: Change in the integral intensity of singlet oxygen-sensitized delayed fluorescence (SOSDF) of erythrosine in stained tissue during 10-pulse excitation (the integral intensity of SOSDF for the first pulse is taken as unity). SOSDF: Singlet oxygen-sensitized delayed fluorescence; DLE: Delayed luminescence of erythrosine.
