ng the musclesand the connective tissues, will also reactin a smiilar manner. The power of resist-ance of tissue thus injured towards furtheradditional injuries, such as traumatic andchemical noxae, or infection, is con-siderably lowered. It during the period of the infiltration(induration) the skin is protected againstall injurious influences, the conditionwill recede in from one to one and a half The prevention of the infiltrations ofthe pulmonary tissue is of decided impor-tance if we wish to improve the results ofradiation therapy of mammary carcinoma. Just as the slightest injury followingirradiation will increase the skin reaction,so acute or chronic diseases which arepresent in the tissue prior to the irradiationmay incite an increased reaction. A greatly increased reaction is to benoted with every gross change in the tissue,because the roentgen treatment introducesan additional noxious agent. Even whenthe skin is only slightly irritated, thisincreased reaction may be observed.

Fic. 5. Radiation induration of tlie lung. years. Far more dangerous is the infiltra-tion of the pulmonary tissue which mayappear after irradiations of mammarycarcinomata or lung tumors. The examina-tion findings of such a lung resemble thoseof a central pneumonia; there is no fever,but a slight irritative cough. The affectedpart of the lung is, of course, useless. Thiscondition is also comparatively harmlessand will recede spontaneously in the courseof one-half to three-fourths of a year. Ifan intercurrent disease (pneumonia orbronchitis) complicates the radiation in-duration, then the prognosis is almostalways bad (Fig. 5). Figure 6 shows a slight irritation of theskin In the anal region at that point In thefield of irradiation where pre\iously anInflammatory erythema was located.
