Typical PT-signal tracings from blood cells in blood and lymph flow: A: RBCs in blood flow; B: rare RBC in lymph flow; C: growing number of RBCs in lymph flow during laser-induced hemorrhage; D: laser-induced damage of RBCs in lymph flow and lymphocytes in lymph flow in linear and nonlinear PT modes; and E: lymphocytes and RBCs in lymph flow. Laser parameters: wavelength, 525 nm; energy/amplitude/time scale/division: (A), 0.3 μJ/50 mV/100 ms; (B), 0.5 μJ/20 mV/1 s/div; (C) 0.6 μJ/100 mV/200 ms/div, (D) 5 μJ/500 mV/4 s/div; and (E) 145 μJ/100 mV/10 s, respectively.
