Abstract

SUMMARYAn adequately large, adequately controlled scries of pneumonia cases were studied. One half were treated with deuteroproteose; the other remaining half received no deuteroproteose, being used as controls.The cases treated with deuteroproteose showed far fewer fatalities, and ran a shorter and milder course, than did the controls.In the cases treated with deuteroproteose, the death rate was less than one-fourth that of the controls. This reduction of mortality is seen in lobar and in bronchial pneumonia, and in all age groups.So in our experience the deuteroproteose is effective in all forms of pneumonia and for all age groups.If the results can be duplicated by others, and if the deuteroproteose treatment could be applied to the whole community, there is ground for hope that it would bring a great reduction in the general death rate from pneumonias for the whole community, a result heretofore never achieved.
