JOURNAL FREE ACCESSParoxysmal ventricular tachycardia is considered to be a relatively infrequent arrhythmia and commonly observed in the presense of organic heart disease. The purpose of this paper is to present a case of paroxysmal ventricular tachycardia for seven years' duration, which arrhythmia was not completely controlled.View full abstractDownload PDF (8999K) -

JOURNAL FREE ACCESSSingle coronary artery is a very rare anomaly which does not reveal clinical evidence and usually diagnosed fortuitously during autopsy. The occasional case of single coronary artery may be difficult to differentiate from idiopathic hypertrophy of the heart.Recently, a patient admitted to our hospital with a chief complaint of shortness of breathing and diagnosis of single coronary artery was made by angiocardiography antemortem. Due to the rarity of this anomaly, a report on this case was prepared.View full abstractDownload PDF (3290K) -

JOURNAL FREE ACCESSNumerous studies on cerebral angiography have been conducted since Egas Moniz's study in 1927.It is known that complications due to cerebral angiography are mainly resulted from the contrast medium. We have selected organic tri-iodide solution as a contrast medium because it is safe and offers a high contrast. Urografin (60% and 76%) were used in 1869 cerebral angiographies. Present studies were conducted to observe complications due to this medium using two concentrations of Urografin.View full abstractDownload PDF (420K) -

JOURNAL FREE ACCESSUsing isolated frog sartorius muscles, tracer experiments and chemical analysis for K+ and Na+ were performed to evaluate the mode that the removal of external K+ or Ca++ affects on the change in internal K concentration.1. During the continuous depolarization of the muscle membrane, K42 efflux was increased continuously while Ca45 efflux was increased transiently. Although the changes in K or Ca efflux showed a parallelism with the change in membrane potential it is reasonable to suppose that the vacancy of the Ca++ or K+ sites of the membrane due to the withdrawal of external Ca++ or K+ is the first step of the change in internal K under these conditions.2. The exchange between ions of the same species takes place, at the membrane, more preferentially than the interchange between an ion and ions of different species. The K+-K+ exchange in Ringer is not qualitatively different from the K+-Na+ interchange in K free Ringer, because these two processes are capable of translating from each other by the condition which is determined by the ionic composition on both sides of the membrane.3. By repetitive stimulation, Na increase within the muscle occurred at the cost of K release in Ringer. This efflux of K+ is different in nature from the net efflux of K+ in K free Ringer. Accordingly, the K ions movable outwards are the adjuster for maintaining the constancy of internal milieu.4. The influence of the removal of external K+ or Ca++ upon the internal K loss takes place by different means. Detail of each process has been interpreted by the change in the pattern of association/dissociation of K or Ca ions with/from the membrane anionic sites.5. Removal of external K or Ca ions first produces the change in the membrane molecular configuration. Then, external K+ influences upon internal K energetically through homogeneous K pool while Ca+ does informationally through heterogeneous pools of K, Ca or both.View full abstractDownload PDF (1256K) -

JOURNAL FREE ACCESSIt has been long established by reports of Kiyono (1914), Aschoff (1924), Arndt (1927), and others that the interstitial capillary system of the adrenal cortex is stained vitally with acid dyes such as trypan-blue or lithium carmine, and that thus it belongs to the reticuloendothelial system (RES), but in regard to whether or not the adrenocortical cells, like the endothelium, have an ability of vital staining there is disagreement in opinion even among light microscopists (see Bachman, 1954).In this paper, the adrenal cortex of mice given gold-sol by intravenous injection was observed electronmicroscopically, and at the same time ATP-ase activity of the same organ of controls was also investigated on the level of electronmicroscope.View full abstractDownload PDF (13145K)
