JOURNAL FREE ACCESS1. The extract of gastric carcinoma in distilled water, Ringer's solu-tion for frogs or 2.5 per cent saline presented an inhibiting effect on the excised frog heart more than four times as strong as that of the extract of normal human gastric mucosa when studied by the kymographic method.
2. When the extract was dialyzed across the cellophane membrane for 48 hours the heart-inhibiting substance was demonstrated in the dialyzate, not in the dialyzed extract.
3. Various chemical and physical treatments were submitted to this substance to study its nature, and it was found that the inhibiting sub-stance was absorbed by cation exchange resin, and soluble in alcohol and chloroform.
In conclusion, I wish to express my sincere gratitude to Assistant Professor K. Ishizuka of the Pharmacological Institute and to Dr. H. Kawasaki of the Medicochemical Institute of Tohoku University.View full abstractDownload PDF (4303K) -

JOURNAL FREE ACCESSBy the method of electro-stimulation, retinal induction was measured at various parts of the human retina.
1. The magnitude of retinal induction was found greatest at about 10° from the fovea. This fact might be correlated with the psychological fact that color contrast can most easily be perceived in the para-foveal region of the retina.
2. Red and green lights were found more effective in producing retinal induction than yellow and blue lights.
3. In measurements of retinal induction two photic stimuli are used, i.e., a colored light preceding a white test light. The intensity of retinal induction was shown to be independent of the intensity and the duration of the white test light, but determined by those of the inducing colored light. This law holds good for both foveal and peripheral vision.
The authors are indebted to Prof. K. Motokawa for his invaluable advice and encouragement.View full abstractDownload PDF (363K) -
Part I. Anatomy of Blood Vessels in Canine HeartItaru Ohara1956 Volume 63 Issue 2-3 Pages 145-151

JOURNAL FREE ACCESSThe blood vessels in 50 fresh canine hearts which were removed from the body were studied. Various injection methods were used to outline its distribution. Models using methacrylate were found to be the best to obtain the relationship of the vessels. Importance of the anatomy in case of studying the effect of ligation of the vessels were emphasized.View full abstractDownload PDF (2313K) -
Part II. Surgical Procedures to Produce Collateral Circulation to Canine HeartItaru Ohara1956 Volume 63 Issue 2-3 Pages 153-169

JOURNAL FREE ACCESSAccording to the anatomical study of the canine heart, abundant collaterals were found existing in the heart. In order to open them up and increase the extracardiac blood flow, coronary sinus was constricted to 3mm. after 1) pericarditis was caused by talc powder, 2) great omentum, and 3) left major pectoralis muscle was sutured to the myo-cardium. The dogs did not survive the ligation of the origin of the anterior descending branch of the left coronary artery. Either single constriction or ligation of the coronary sinus did not protect the heart from ligating the anterior descending branch. Such procedures to prevent the outflow of of the coronary venous blood do not seem to contribute to increase the intercoronary anastomosis.
Implantation of the left internal mammary artery into the myocardium will make good anastomosis with the heart muscle as far as it is patent. However, the incidence of thrombosis is considerably high.
As dissection of coronary sinus is met with imminent bleeding, an-astomosis is quite difficult to establish complete arterialisation of coronary sinus. The procedure cannot be recommended as a safe operation.
The work was supported by grants for the research group of Coronary Circulation and Cardiac surgery from the Scientic Research Fund by the Edu-cation Ministry, 1953, and 1954, respectively.View full abstractDownload PDF (5117K) -

JOURNAL FREE ACCESS1. The glomerular filtration rate, renal plasma flow, renal blood flow, filtration fraction and calculated renal vascular resistance were estimated in 5 normotensive, 20 benign and malignant hypertensive and 5 renal hypertensive subjects.
2. The acute effect on renal hemodynamics of hexamethonium, veratrum alkaloids or apresoline, parenterally administered, were investigat-ed in 28 hypertensive patients including 23 benign and malignant hyper-tension and 5 renal hypertension.
In benign hypertension, there were in general an increase in renal plasma flow, renal blood flow, and a reduction in filtration fraction or renal vascular resistance following the administration of each hypotensive agent, but glomerular filtration rate shows a slight increase after hexa-methonium and no change or slight decrease after veratrum or apresoline.
In malignant hypertension and in renal hypertension, though in the latter to a less degree, the glomerular filtration rate, renal plasma flow, renal blood flow and filtration fraction are reduced, common to all three drugs, but renal vascular resistance shows a depression after veratrum and an increase after hexamethonium or apresoline. Differences between the responses to each agent are not significant.
3. It is discussed whether or not artificially lowering blood pressure using hypotensive agents is advantageous in hypertensive patients; further, the indication for the blood pressure reduction is argued.
Part of this paper was presented at the 18th Annual Meeting of the Japanese Circulation Society at Nagoya, April 1954. The expense of this study was in part defrayed by a grant in Aid for Medical Research from the Medical Affairs Bureau, Welfare Ministry.View full abstractDownload PDF (716K) -

JOURNAL FREE ACCESS1. The specific antigenicity demonstrated in the alcohol extract of human gastric cancer was traced by preparing rabbit antisera against alcohol extracts of human gastric cancer, normal gastric mucosa, performing complement fixation tests of these antisera, aided by absorption tests, with chemical fraction of the extracts, and continuing the fractionation until the fraction responsible for the specific antigenicity could give a single peak in an electrophoretic pattern when submitted to electro-phoresis.
2. Two substances specific to human gastric cancer have been isolated. They are closely related with each other. Each substance is a single one (not a mixture of two or more substances), presumably consisting of phospholipid and glycolipid.View full abstractDownload PDF (1999K) -

JOURNAL FREE ACCESSWith a view to tracing the specific antigenicity of human gastric cancer a series of experiments were carried out, which essentially consisted of (1) producing antisera in rabbits by injection of saline extracts of human gastric cancer, normal gastric mucosa, and placenta, (2) preparing several purified fractions of the above three kinds of tissue, which were used as antigens for precipitin tests, and (3) performing reciprocal precipitin tests aided by reciprocal absorption tests. It has been demonstrated that the nucleic acid fraction of human gastric cancer presented the highest antigenic specificity, the glucidamin fraction a modertae, and the carbohydrate fraction least specificity.View full abstractDownload PDF (690K) -

JOURNAL FREE ACCESSIn order to investigate the intermediate metabolism of water, proteins, carbohydrates and electrolytes, in the kidney in experimental hyper-tension, the contents of these substances in the renal venous blood were estimated and compared with those in the arterial blood in normal rabbits as well as in the rabbits made hypertensive by the method of Goldblatt. The comparison of the corresponding data taken from both kinds of animals revealed following facts.
1. The release of water from the circulating blood into the kidney tends to be somewhat decreased in hypertensive animals.
2. The discharge of proteins from the blood into the kidney is aug-mented in hypertension. This increment is mainly due to albumin; on the contrary, globulin, especially β- and γ-globulin are transferred in a large quantity from the kidney into the circulating blood.
3. The discharge of blood non-protein nitrogen into the kidney tends to be reduced in hypertensive animals.
4. In hypertensive animals, the release of blood sugar into the kidney is augmented, while that of lactic acid is decreased.
5. Of the electrolytes in blood, the release of Cl and Na into the kidney is below normal; in some cases Cl and Na are transferred, though a little, in the reverse direction so that their contents in the renal vein are increased over those in arterial blood. The transfer of K and Ca into the kidney is increased over normal.
6. The rise of pH during the intrarenal circulation tends to be slightly augmented in hypertensive cases.View full abstractDownload PDF (609K) -
