As the blood stream passesthrough the radiated part, the cellularconstituents of the blood as they passthrough receive a charge of the radia-tions. It is thus evident that deeptherapy affects the entire volume ofblood in the body. Some Factors Which Determine theTissue Changes 1. Dosage of radium or x-ray atsource. 2. Tlie distance of the radio-active 302. Figure I —Wound left open for »ub-eeqaent application of either x-rayor radioni. substance or the anode from the body. 3. The length of time of exposure. 4. The thickness of the intervening tis-sues. 5. Interposition of artificial filters, theirdensity and thickness. liesults of liadialion upon the Tissues 1. Small amount of radiation has thetendency to accelerate the growthof the tissues: it causes proliferationof the cells. (This has been con-tested.) 2. Larger doses will paralyze the re-productive power of the cells andthus retard or entirely inhibit thegrowth without actually destroyingthe life of the cell. 3. Massive doses will destroy the lifeof the cell. It is disintegrated and the end products are absorbed inthe body and eliminated throughthe excretory organs. This applies to all living cells, butsome cells are more resistant thanothers to radio-active application. Changes in Normal Tissues: Theinvestigations of this subj
