JOURNAL FREE ACCESSThe importance of the arteriovenous crossing as the site of tributary occlusion has been confirmed fluorescein angiographically by many authors. However, the grade and location of venous obstruction in an arteriovenous crossing have still been controversial.In previous report we have informed an interesting finding that two types of venous obstruction were shown at an arteriovenous crossing, and we have briefly discussed its significance.The purpose of this paper is to more clarified the findings of an arteriovenous crossing by fluorescein angiography.View full abstractDownload PDF (3788K) -

JOURNAL FREE ACCESSBacterial L-form can survive under conditions unfavorable for maintaining bacterial life. For this reason, the possibility that bacterial L-form may participate in the occurrence of infectious diseases, especially of subclinical chronic diseases, in man has been proposed by many investigators . On the other hand, there are reports that antibiotics, lysozyme, antibody, complement, bacteriophage, etc. which can prevent bacterial cell wall synthesis are also factors that produce L-form. These facts give rise to a hypothetical idea that the production of L-form is probably one of side effects of antibiotics which are, at present, extensively used for treatments of various infectious diseases. Furthermore, there are few reports to indicate that inadequate administration of antibiotics may result in the production of L-form.To solve a problem that when bacteria in L-form are present in the kidney as a mode of life of bacteria what kind of effect they have on renal functions is considerably important, not only for evaluating diagnostic methods, disease progress or treatment of pyelonephritis but for discussing pathogenesis of L-form bacteria.I have investigated the significance of bacterial L-form in provoking pyelonephritis as a clinical requirement in my course of study. This report deals with the results of bacteriological, pathohistological and electron microscopic examinations which have been made after injecting L-form prepared in vitro into normal rats.View full abstractDownload PDF (13843K) -

JOURNAL FREE ACCESSIt is well recognized that MCT (Medium Chain Triglyceride) has a favorable effect on growth of infants with malabsorption syndrome due to impaired fat digestion or absorption.The Low Birth Weight Infants (LBWI) have temporal malabsorption, because of poor butter fat absorption. This is especially true within first 30 days of the infants life. Although absorption of fat is improved using half skimmed milk or milk fortified with vegetable fat, it is still insufficient.The excellent absorption of MCT in the LBWI has been confirmed and the application of MCT substituted milk for the LBWI nutrition was reported with better weight gains (Yamashita, F. et al., 1967).The purpose of this study is to confirm the above data utilizing the Latin square technique in order to contribite both accuracy and impartiality to the results.View full abstractDownload PDF (1486K) -

JOURNAL FREE ACCESSTo reaffirm hemodynamically the electrocardiographic criteria for the evaluation of an optimal exercise level proposed by N. Kimura in 1956, exercise study was performed in 86 patients with ischemic heart disease and/or concomitant systemic hypertension. Cardiac output at rest and after a roughly estimated level of exercise was determined by means of Dye-dilution technique using Earpiece method. The following results were obtained.1. After exercise such as to cause more than 1 mm of ST depression, mean cardiac output increased scarcely and mean stroke volume decreased. This exercise level developed insufficiency in coronary flow so that this was indicative of excessive cardiac load.2. Following exercise such as causing more than 1 mm of ST elevation, this exercise level might be suggestive of excessive cardiac load, although the statistical significance in their hemodynamic responses was not available because of the lack of cases.3. The subjects showing significant changes of T wave but no deviation of ST segment after exercise were divided into the 3 groups ie, group 3, 4, 5, according to the type of T wave changes.In each of these 3 groups, however, both mean cardiac index and mean stroke index increased modestly to the identical level regardless of T wave changes. As a whole the statistical significance in the mean hemodynamic responses was discovered only between group 1 and group 3, 4, 5. Although group 3 showing postexertional flattening of T wave wiuhout significant deviation of ST segment might be indicative of an optimal load, its validity has remained equivocal for some reasons as described before. Therefore only these exercise levels such as causing shallowing of negative T wave or augmentation of positive T wave without any significant deviation of ST segment were considered to be optimal for any patient except for cases showing an unusual augmentation of T wave.4. In conclusion the present study demonstrated that the electrocardiographic criteria for physical training proposed by N. Kimura was valid as a whole not only in the clinical practice but also in the hemodynamic aspects.Several interesting problems which made the decision equivocal has remained unsolved, however.View full abstractDownload PDF (2830K) -

JOURNAL FREE ACCESSEmbryonal carcinoma of the testis was examined by electron microscopy. In the undifferentiated epithelial cells the normal feature of the germinal cells were well preserved whereas in the solitary cells, dense and homogeneous granules were found out inside the cavities of the rough endoplasmic reticum in addition to the usual structural changes specific for the malignant tumor cells. These granules resembled strongly to the intracisternal granules in the exocrine cells of the pancreas.View full abstractDownload PDF (11159K) -

JOURNAL FREE ACCESS1) 45Ca efflux from the isolated frog sartorius is usually characterized by a transient increase in it when some factors to increase membrane permeability have been applied to the muscles. Occasionally, the 45Ca efflux increase becomes continuous. The intracellular ionic properties which are common to the conditions for a continuous increase in 45Ca efflux have been investigated with special reference to the behavior of Ca ions.2) Although when Ca free Ringer and high K Ringer were successively, but independently, applied to the muscles 45Ca efflux from the tissue showed a transient increase in response to the treatment with each solution, the 45Ca efflux was accompanied with a continuous increase when both conditions were simultaneously applied to the muscles. Combination of trypsin and ouabain caused a continuous increase in 45Ca efflux. The treatment with Ca free Ringer containing Sr, Mg or Ni at the concentrations which could not prevent the appearance of a transient increase in 45Ca efflux producible by Ca free Ringer also resulted in a continuous increase of 45Ca efflux. In a similar situation, Ba and Cu ions could not demonstrate such a change.3) The conditions to generate a continuous increase in 45Ca efflux from the muscle are supposed to be the factors which cause a rise of intracellular Ca++ concentration simultaneously with mobilization of membrane Ca++. The former change is probably brought about by influencing upon the activity of the sarcotubular system. When the latter process is conspicuous 45Ca efflux increase may be transient in nature.View full abstractDownload PDF (1028K)
