I. On the Relation ot the Coronary Blood Flow and the ST-deviation in the ElectrocardiogramEiichi Kimura, Norio Suzuki, Tomohiro Kanazawa, Yoshio Ito, Nobuo Hari ...1957 Volume 66 Issue 1 Pages 25-32

JOURNAL FREE ACCESS1. The critical or threshold value of the coronary blood flow for the ST-depression was measured in 19 dogs by the bubble flowmeter connected to the cannula inserted into the orifice of the left coronary artery.
2. The normal value was measured as 150 cc./100g. of left ventricle/min. in the open-chest dog anesthetized with pentobarbital under artificial respiration.
3. As the coronary flow reduced, the ST-depression appeared. This critical value of flow was measured as 50-60 cc./100g. of left ventricle/min.
4. The ST-depression disappeared reversibly when the coronary flow was augumented by the intravenous injection of the hypertonics in the hypotonic states.
5. By means of approximate calculation the coronary flow of this level fairly coincides with the lowest value to fulfil the myocardial oxygen demand.
6. From above considerations, the current view, that the reduction of the coronary flow or the defficient oxygen supply for the myocardium is the cause of the ST-depression, is verified directly.View full abstractDownload PDF (369K) -
II. The Relation of the Coronary Blood Flow to the Arterial Blood Pressure, and the Effect of the Vagus Nerves upon ItEiichi Kimura, Tomohiro Kanazawa, Norio Suzuki, Yoshio Ito, Nobuo Hari ...1957 Volume 66 Issue 1 Pages 33-41

JOURNAL FREE ACCESS1. The relation of the coronary blood flow to the arterial blood pressure was analyzed using the experimental data reported in the preceding paper. In general, the fall of the blood pressure was accompanied by the diminution of the coronary flow.
2. As a rule, the correlation rates were higher in the severed vagal cases than in the intact vagal cases.
3. In the spontaneous blood pressure fall the correlation was signific-ant even in the intact vagal cases, though it is not so high. This may be attributed to the lowered function of the vagi as a result of “weakening” of the heart.
4. From above observations it was supposed that the vagus nerves act to maintain the coronary flow when the arterial pressure falls criti-cally; that is to say, they act as a safeguard equipment.
5. On the other hand, the arterial pressure showed no changes when the coronary flow primarily reduced. The vagus nerves played no part on it.View full abstractDownload PDF (1550K) -

CCIII. A Glucidamin and a Molisch-positive Mucopolysaccharide from Human LungHajime Masamune, Zensaku Yosizawa, Katuhiko Tokita1957 Volume 66 Issue 1 Pages 51-60
Published: June 25, 1957
Released on J-STAGE: November 28, 2008
JOURNAL FREE ACCESS1. A glucidamin- and a mucopolysaccharide-preparation were obtained from lungs of Group A persons and from those of Group O persons, and examined regarding their properties physical and chemical.
2. The glucidamin from Group A lungs is Group A active, but that from Group O lungs slightly inhibited agglutination of Group O, A and B erythrocytes by the respective antibodies, which might be ascribed to group interconversion during preparation. The mucopolysaccharide from lungs of Group A persons and that from lungs of Group O persons are both group inactive.
3. The glucidamins differ from each other in quantitative com-position as well as in optical rotation, whereas the mucopolysaccharide preparations have resembling compositions and rotations, indicating their identity. The sugar components of the glucidamins are galactosamine, glucosamine, galactose, mannose and L-fucose. The mucopolysaccharide contains glucose and xylose and/or lyxose besides the sugars in the glu-cidamins.View full abstractDownload PDF (818K) -
Fifth Paper: on Placental Itinsulfuric AcidsHajime Masamune, Hirosi Yosizaki1957 Volume 66 Issue 1 Pages 61-72
Published: June 25, 1957
Released on J-STAGE: November 28, 2008
JOURNAL FREE ACCESSFrom fresh placentas were isolated three itinsulfuric acids most probably containing acetylgalactosamine and glucuronic acid as sugar components. One of them was proved to play no role in inducing pregnancy toxemia.

JOURNAL FREE ACCESSSeventeen male albino rats of the Lister strain were fed a diet containing 18% Japanese brewer's yeast as the sole source of dietary protein. One rat died of pneumonia. Eight rats (50%) died from massive hepatic necrosis after receiving the diet for 24 to 48 days (average:33 days). The chief histological changes in the livers of rats which died from hepatic necrosis were massive coagulative necrosis with fatty infiltration and hemorrhage. It is concluded that Japanese brewer's yeast may be relatively capable of producing dietary hepatic necrosis, for it may be deficient in cystine, α-tocopherol and Factor 3.View full abstractDownload PDF (1368K) -

Part I. During Fixation of the GazeTetsuya Kuboki1957 Volume 66 Issue 1 Pages 91-96
Published: June 25, 1957
Released on J-STAGE: November 28, 2008
JOURNAL FREE ACCESSThe action potentials of normal extraocular muscles of a man were induced, and the discharge intervals of a single motor unit were observed during fixation of the gaze.
1. During fixation of the gaze on a point, the discharge frequency of a single unit is constant, but, if the gaze is moved to another point, it varies with the degree of contraction of the muscle in experiment.
2. When the average rate of discharge is over 30 per second, the variation of discharge interval is very small and the patterns of interval diagrams are uniform.
3. When the average rate of discharge falls below 30 per second, the variation of discharge interval increases and the patterns of diagrams give various types.
4. When the average rate of discharge is below about 10 per second, regularity of the discharge is scarcely found.View full abstractDownload PDF (1433K) -
Part II. During Horizontal Movement of the EyeTetsuya Kuboki1957 Volume 66 Issue 1 Pages 97-105
Published: June 25, 1957
Released on J-STAGE: November 28, 2008
JOURNAL FREE ACCESSThe action potentials of internal and external rectus muscles of a man were induced during a slow horizontal movement of the eye, and the behavior of a single motor unit were investigated by observing its discharge intervals.
1. During a horizontal movement of the eye, discharge intervals of a single unit in the agonist as a rule, decreased, and those in the antagonist increased, but the behavior of each unit varied so much.
2. A striking fact is that some units were often observed discharging with rather constant and high frequencies, regardless of the movement of the eye.
3. Each unit of the internal and of the external rectus muscle had its own range of action fixed to the movement of the eye.
4. The difference between the impulsive and the gliding movement did not always appear in the behavior of each single unit.
5) In the extremest movement of the eye out of the muscle field, the activity of the antagonistic muscle never fell off to zero.
6. Moreover, a few units in the antagonistic muscle were sometimes observed to increase its rate of discharge in the same movement.View full abstractDownload PDF (1421K)
