    Promotive factors to lower seriously the mean tissue oxygen tension of the right ventricle were mathematically calculated by means of digital computer, considering that congestive cardiac failure In pulmonary heart diseases was caused by the oxygen deficiency in the right ventricular muscles. One of factors would be pulmonary hypertension related to alveolar hypoxia or asphyxia caused by disturbances of pulmonary gas exchange, and the other would be relative coronary insufficiency due to increase in works of the right ventricle caused by pulmonary arterial hypertension and decrease in coronary blood flow. Also, the results suggested that right ventricular hypertrophy itself predisposed relatively little to congestive cardiac failure. Therefore. in most cases without complications such as mechanical disturbances of coronary vessels, arteriosclerosis, and so forth, could pulmonary infections be protected, clearing of airways be maintained and arterial gas compositions would remain within normal limits, signs of congestive cardiac failure would not appear even if there existed much impairments of tissues in the lungs.

    Various mamalian red cell angiotensinase activities and their apparent Km values were compared. The strongest angiotensinase activity was found in the human red cells. Aminopeptidase activity and the angiotensinase activity not being the same suggested the presence of one other angiotensin inactivating enzyme besides aminopeptidase.

    The purpose of this study is to clarify the relation between vectorcardiographic configuration and hemodynamic factors of atrial septal defect (herein after refered to as ASD) Many authors made vectorcardiographic studies in ASD to date. The vectorcardiograms in ASD are known to show a unique configuration of counter clockwise rotation and terminal bunching on horizontal plane. However, the qunatitative analysis of the foregoing is rather complicated, in that, each instantaneous vector has no specific tendency as to magnitude and direction. Therefore, the condition of ASD derived from vectorcardiogram has always been qualitatively. It is now important to realize how much information of hemodynamics will be brought out from vectorcardiographiq parameters. Instead of the instantaneous QRS SE vector, the sequential composite QRS SE vector was used as vectorcardiographic parameter. The advantage of this method are: 1) to be able to effectively adopt as the parameter the terminal bunching vector having prolonged duration time. 2) to be able to comprehend as a whole each instantaneous QRS sE vector which may vary from time to time. For the prediction of the severeness in ASD from vectorcardiogram, the author made a comparison between sequential composite QRS sE vectors and hemodynamic factors using multivariate analysis. Method A total of 27 cases, 15 males, 12 females, ranging from 14 to 62 years of age with ASD (ostium secundum) were studied. Chest X-ray, phonocardiography and right ventricular catheterization were used to establish and comfirm the diagnosis of ASD. The three planar projections of vectorcardiogram were photographied on 60 × 60 mm X-ray films simultaneously by three channel vectorcardiography useing the Frank system. The method of morphological observations and quantetative analysis are as follow.
