Microscopic details from the 297 pulse treatment.

(A) and (B) Low magnification micrographs from different sites of the middle region between electrodes. (C) and (D) 10x and 20x magnification of the tissue in the area midway between the electrodes. (E) and (F) 20x magnification of tissue adjacent to the large blood vessel, with sites in the area midway between the electrodes (E) and tissue near the large blood vessel on the side of the right electrode (F). (G) and (H) Micrographs from sites in the core of the region affected by the right hand side electrode. (I) and (J) Micrographs from sites at the right hand side, outer edge of the right electrode. The sites from which the magnified micrographs were taken are marked with a square in the insert. Scale bars and magnification are given in the figures.
