Light microscopic and electron microscopic study of the cells of tissue cultures irradiated with a neodymium laser]

Damage of tissue culture cells (Hela, a human amnion, a primary rat liver culture) caused by the neodymium laser radiation was studied by time-lapse phase-contrast microfilming and electron microscopy. The tested cultures were shown to display different sensitivity and the degree of cell alteration within the same cultures varied considerably. A physical mechanism of cell damage is probably of thermal and shock-wave nature.
