Fig. 71^—Switchboard Type Interrupterless Machine Radiotherapy Radiotherapy, or the treatment by means of the X-rays, must be con-sidered from two points of view: Stimulation and Inhibition. Small doses (short or mild exposures) of the X-rays produce thestimulation of the tissue (increase the cytolitic growth activity withmore rapid mitosis, and increase the number of cells). Large doses (considerably long exposures) produce an intensely in-hibitory action (cause pyknosis and nuclear disintegration, and latervacualization and rupture of the cytoplasm, resulting in the death of thecell), arresting all active processes, and destroying tissues of varyingresistance, relative to the character of the exposure and the suscepti-bility of the tissue to the overwhelming influence of the radiations. 122 Anthony Matijaca The cells of low vitality are more susceptible to the action of the X-raysthan normal cells (which have many times the resistance of diseasedcells). Due to this fact, the disea
