Mice and Men against Pneumonia FOR MEDICAL RESEARCH PURPOSES, the white mice you see above are almost miniature hu man beings. Their reaction to the pneumonia germ and to cer tain methods of diagnosing and treating pneumonia have been of invaluable help in the dramatic strug gle waged by men and their little laboratory-help ers, mice, against death from this disease. • Perhaps you do not realize how much progress has recently been made in this struggle-that the death rate from pneumonia has dropped nearly one half in the past ten years. Diagnosis of pneumonia is now more certain, de termination of the type more accurate. Serums have been developed which are highly effective in combating the disease-provided they are given in time. New chemical compounds also are playing an important role in the control of pneumonia. That this progress offers so much hope of relief and cure gives you more reason than ever to be on the alert for pneumonia's danger signals. More rea son, too, for letting your doctor know about them promptly, and thus give him the opportunity of determining as soon as possible which treatment is most appropriate for your particular case. • Though pneumonia may strike without warning, the most common symptoms usually appear after a cold or grippy infection or some extreme exposure or exhaustion. These symptoms consist of: Sudden chill. Fever. Pain in side. Cough. Thick, rust-colored sputum. Hurried, somewhat labored breathing. Any one or any combination of these symptoms in dicates illness which may be pneumonia. So, a doc tor should be called at once. Tragic situations have resulted from delay in seeking medical treatment. Pneumonia works fast, and the physician must work faster to check the disease. Throughout winter and early spring, colds and pneumonia are most frequent. During those coming dangerous months, much can be done to keep your resistance high to these infections. Write for Metro politan's free booklet, "Colds, Influenza, Pneumo nia," which contains many practical suggestions to help you ward off trouble. COPYRIGHT I939-METROPOLITAN LIFE INSURANCECO.
