Sensitivity of biological tissues and cellurar cultures to repetitive submicrosecond microwave pulses

The effect of repetitive pulsed microwaves (10 GHz, 100-300 ns pulse duration, 4-25 s
^-1
pulse repetition rate, 0.7-17.4 kW/cm
²
peak power density) on mastocytoma P815 and Ehrlich carcinoma was investigated. Short-time irradiation of these tumors at 0.9-1.5 kW/cm
²
inhibited proliferation of tumor cells, induced oxidative modification of macromolecules, and changed the impedance characteristics of a mitochondrial suspension of mouse hepatocytes, stimulating the wound healing. The effects showed a dependence on pulse repetition rate and irradiation intensity.
