A. Transmission electron micrograph of typical cardiac capillary (scale bar – 1.0μm). B. Perivascular space edema in the cardiac sample after straight freezing in liquid nitrogen under normal pressure (scale bar – 1.0μm). C. Capillary damage after incubation at high-pressure nitrogen-oxygen gas mixture and cooling in liquid nitrogen (scale bar – 1.0μm). D. Intact capillary endothelial cell after applied cryostasis (incubation in high-pressure xenon-oxygen mixture followed by cooling in liquid nitrogen) (scale bar – 1.0μm).
