    Experiment was undertaken to evaluate the effects of acidosis upon the susceptibility of the heart by measuring digitalis tolerance, myocardial contractility, and ventricular fibrillation thresh-old. The significant reductions in acetyl stro-phanthidin tolerance, left ventricular contractile force, and ventricular fibrillation threshold value were found during metabolic acidosis induced by lactic acid infusion, whereas they were maintained at almost control values during respiratory acidosis. Moreover, the decreased myocardial contractility after total body perfusion was relative to the decreased arterial blood pH caused by the metabolic factor.

    In order to identify the effects of meteorologic factors, their changes or combinations upon attacks, 74 cerebrovascular accidents which occurred in Nago-ya, 1965 were investigated. The excess attacks of cerebral hemorrhage were found with statistical significance when temperature-humidity index and MISSENARD's effective temperature were low, when air temperature, relative humidity and atmospheric pressure were decreasing and when the grade of de-crease of air temperature became more, or when that of increase less remark-able. And cerebral hemorrhage or infarction were more frequently noted at high atmospheric pressure. Some preventive measures against cerebrovascular accidents were suggested with brief discussion on the importance of the further investigations on physiological responses to meteorologic conditions and the relative evaluation of meteorologic effects upon attacks.

  • Changes of Blood Cells at High Altitude

    An improved method for acquiring acclimatization to high altitude has been developed in Mt. Kenya and Mt. Kilimanjaro, in East Africa: Resting on a highland after exposure to high altitudes of 5, 000m, gives one the ability to climb to 6, 000m without symptoms of mountain sickness. Changes in blood components are checked by a direct counting method, one which is seldom used because of inconvenience. Though RBC de-creases at the beginning of the first ascent, it in-creases, during the second ascent, in proportion to the height of the mountain. The granulocytosis of the bone marrow may be disturbed when there is oxygen deficiency, and matured or aged leucocytes having five segmental nuclei increase. It is suggested that changes in serum protein are the result of complicated metabolic changes.

  • Arteriosclerosis in Spontaneously Hypertensive Rats on High Fat Diet

    Spontaneously hypertensive rat is a good model fashion for the production of arteriosclerotic lesions in peripheral arterial trees of rat. Common carotid arteries and sinus areas and peripheral arterial trees are well recognized sites of predilection for arteriosclerosis and this arteriosclerotic lesion produces the vascular walls rigid in high-fat diet fed hypertensive rats. Blood pressure response after sinoaortic denervation gives very low response or no response at all according to the grade of severity of arteriosclerotic lesions.

    A 13-year-old boy with supra-aortic stenosis syndrome was presented, characterized by association of peculiar facies, mental reterdation, multiple peripheral pulmonary stenosis, and tortuosity of the retinal vessels. This is the first case in Japan.
