Pleurisy was next with 14. 2%, Pneumonia 13. 4%, lung tumor 12. 0%, bronchial asthma 7.9%, bronchiectasis 4. 5%, chronic obstructive pulmonary disease (COPD), 4. 3%, pneumothorax 2. 2%, lung abscess 1. 4%, cor pulmonale 1. 4% and miscellaneous 2. 5% of respiratory cases. 4) The incidence of bronchiectasis increased about two and half times during the five years and brochial asthma decreased somewhat, while ehronic obstructive lung diseases steadily increased. 5) Among the patients of pulmonary tuberculosis or tuberculoss pleurisy. Diabetes mellitus was found in 12.7% of patients and liver diseses was fonud in 5. 3% of patients. 6) Among 234 patients of pneumonia, etiological agents were found in 45.3%, Gram negative bacteria was found in 14.0%, mixed infection 10.8%, staphylococcus. 8.9% and pneumococcus 6.0% respectively. 7) Among the pleurisy patients, tuberculous pleunrisy was found in 63.6% , which was prevalent in youth.
