    For Schlatter's disease which prepubescent people complain or the pain and ebulation of tuberositas tibiae, and shows the ablation phenomenon by radiographic appearnce, many treatment methods have been reported from old times. Broadly speaking, there are two remediest-the conservative therapy and operative therapy-and it takes many days to cure it (taking either case), and it often recidivates. We took this disease as being a kind of avulsion fracture seen in prepubescent people, reducing it, and adopting a fixing method by 22-A Steel Screws. The method was easy, and the clinical effect shown to be an early vanishing of the pain (the moving pain vanishes within 3 weeks, the local pressure pain within 6weeks) and on the Radiographic apperance, the diastasis in the tuberositas tibiae being closed largely. The regeneraticn phbenomanon by the local stimulant was promoted, and the intention was acted comparatively quickly. By these results, we can assure you that this method is sure and simple, its recidivation is rare, and the method is worth recommending.

    I have tried experiments on wave form of X-ray tube current and studied about it in theory. In experiments I measured X-ray dose by film blackness method, and in theory evolved the simple theorefical expressions, and noticed that the X-ray dose of a single phase differ from that of three phases. Moreover acquired a ratio of both X-ray dose, I was able to compare the consequence of experiments in a single phase with that of three phases easily.

    Observing the wave form of X-ray tube current, I have noticed that the phase (θs) where the wave current moved from space charged zone to saturated zone, changed the spectre of tube voltage and influenced the X-ray quality considerably. And then, not only from the experiments but also in the theory, noticed that the changes of tube voltage influenced the mean value of tube current by change of the spnce charged zone and saturated zone, even though neglected the Schottky effect.

    We don't think it important in general, but I studied about X-ray quality influenced by X-ray tube current in a single phase. In experiments measured X-ray dose by film blackness method and observed the wave form of X-ray tube current by oscillogram, and in theory evolved the simple theoretical expressions. And then, not only from the experiments but also in the theory, recognized that the influence was considerable, and explaind the factor which concerned the influence.

    We think the X-ray dose and the X-ray quality is similar by halfwave-rectified or allwave-rectified generators, if tube-voltage and tube-current is in same condition. But I could estimate that the dose and the quality have some difference between both generators, from my experiments of wave form, and in experiments observed the wave form of X-ray tube current by oscillogram, and in theory evolved the simple theoretical expressions. And then, not only from the experiments but also in the theory, recognized the both difference are considerable.

    The study about wave form of X-ray tube current has not been taken place in general, and so, even if the electric source is different, we often think it. same. But I found that the X-ray quality and the X-ray dose were considerably changed by wave form of electric source, and recognized the change that I have supposed, after comparing with the varied condition. And then, the comparison of X-ray quality used by X-ray spectrum is not practical, so I noticed to analogize X-ray quality from spectrum of X-ray tube voltage. And about oscillogram that was gained by leading the tube current io vertical axis of oscillograph and leading the tube voltage to horizontal axis, we can compare the X-ray quality from the proportion of length of projection that an oblique line and horizontal line projected to horizontal axis, when the tube voltage is equal, and when the tube voltage is varried, we can compare the X-ray quality from the vaule of em. And I recognized that the method was accurate.

    The diagnostic worth of the Chest Roentgenogram seems to be attributed to the affairs that the blood vessel shadows are clear and the ends of them also can firmly be followed up. Now, when the tube voltage is variously changed, what differences should appear on the blood vessel shadows? Analyzing and investigating, I have made clinical observations regarding the phenomena from both sides of the primrry rays and the scattered rays. The lower the tube voltage is, the more clearly the change of the X-ray contrast reaches to the middle part of the blood vessel; moreover, the finer the blood vessel is, the more remarkable the teddency become. And the scattered rays have the tendency to harm the image, if the tube voltage is higher than 80kVp-90kVp. On the contrary, when the tube voltage is higher than 80kVp-90kVp, the X-ray contrast will happen only nearer the blood vessel;and the higher the tube voltage rises, the larger the volume of the scattered rays become : ; and the higher the tube voltage rises, the larger the volume of the scattered rays becomes; accordingly it has the tendency to make the contrast worse. But as for “unsharpness”, it does not harm the image too much. When the two tendencies of the primary rays and the scattered rays are uniten and, besides, the tube voltage is low, it is thought that the blood vessel shadows are unclearly seen and hard to be followed up. In addition, this has well been concordant with clinic observations. Therefore, in case of combination of the present day film and the intensifying screen, the tube voltage of 80kVp-90kVp is more excellent than the photography heretofore in use. So-called high voltage technique is recommendable. if man uses a movable grid which can completely remove the stripes.

    Though, hitherto, we have had the tendency that our attentions have been drawn only to the image of the section, when we diagnose the pathologic changes of the lung by X-ray tomography, it is clear that the images on one tomograph are never made up of only that of a section, when we reconsider the principle of tomography. I think that attentions must be also paid to the scumble of images of the object in the “extra section”, when we diagnose the image of the section on one tomograph. I have classified theoretically the tendencies of X-ray distribution on the film, which are occured by the objects in the “extra-section”, into two components. One is the part of decreasing distribution and the other is that of increasing distribution. The scumble of images of the object in the “extrasection” is formed by the combination of those two components. Confirming the theory by the experiment of film blackening method, I have realized that the theory is right.

    Out of the non-estrogenic acid fraction of pregnant mare urine a christalline component (provisio-nally called synstrone C) was isolated by means of adsorbtion to activated carbon, elution by phenol and chromatography. This substance did not show estrogenic activity by itself, but it augmented estrogenic hormone in some degree, if given simultaneously to spayed mature female mice. On the other hand the same substance brought similar reaction to that of progesterone in uterine stromal nuclei of spayed mice according to the progestin test of Hooker-Forbes. The substande synstrone C included nitrogen in 17% and displayed a characteristic fluolescence if concentrated sulfuric acid was added.

    In order to recognize the pathologic changes in the lung more clearly, x-ray films are taken from various angles and position. “Spitzenanfnahme” is one of them. While the author was studing the tendencies of the X-ray distribution in “extra section” in tomography, the possibility of utilizing the principles of “Spitzenaufnahme” to this method was considered. By modifying the moving angle and the radiating direetion of X-ray tube on the prinaple of “Spitzenaufnahme”, satisfactory results were obtained where images of clavicle bone and other artifacts were removed.

    Serum specimens were collected from 104 cases with hemolytic streptococcus infection anb the relationship between antistreptolysin-O titre and percentage of serum protein fractions were observed. Total serum protein concentration and β-globulin fraction showed no definite tendency. Albumin showed a slightly decreasing tendency as the ASL-O titre increased. α1-globulin showed a decreasing tendency and this trend was significant though it was slight. γ-globulin was enhanced definitely with the increasing of ASL-O titre, the regression coefficient was 0.34 and this value was significant at 0.1% level.

    Formerly Abe (1956, 1957) produced the “penicillin-hypersensitive” strain (P.H.S.) by making Staphylococcus aureus acriflavin-resistant. In the present investigation Qo2 of normal (N), penicillin resistant (P. R.) and PHS strains were estimated. The results were as follows : These results suggest that in P. R. strain. the intracellular concentration of flavoprotein enzymes is high and that of cytochrome-cytochrome oxidase system is low, and in P.H.S. strain the relationship is reverse, as flavoprotein plays a principal role in the oxidation of alanine, and cytochrome system does in that of glutamic acid. When riboflavin, a metabolic inhibitor of flavoprotein enzyme, was added, the oxidation of l-alanine by N and P. R. was inhibited in some exent, but in the case of P. H. S. the rate of oxidation was unaffected. These results may support Abe's opinion (1957) that a decrease in cytochrome system. and a compensative increase in flavoprotein enzymes occur in P.R. strain.

    Studying the relation between the temperature of R-ray tube filament and the heatervoltage or the heatercurrent experimentally and theoretically. We find the fact that emission of election from filament depend upon the temperature of filament, perhaps we shall be able to make use of this relationship when we study the appearance of emission hereafter.
