“Congenital subluxation of hip” in this study means disposition of dislocation, kysplasia or hypoplasia of acetabulum, or developmental malformation after manipulative reduction. This condition may often develop pain, limb or abnormal fatigue by 12 to 13 years of age. For the relief of these symptoms, various operations may be performed, and one of them is Schelf Operation. There have been many papers which reported that this operation will result functional stability and reduce symptoms.
The authors performed the operation in 12 cases, in 14 joints, and have checked the effects of the operation. The follow up period were 1 year to 3 years. The results were classified into “very good”, “good”, and “fair” or “improved”.
Two joints were “very good”, 5 joints, “good”, 4 joints, “fair” and the other 3 joints, “improved”. The followings are our conclusions;
1) In case of Schelf operation, strong traction for several days before operation, placing of caput femoralis as far down as possible at the time of operation and building of the Schelf as large enough to cover the caput femoralis without abduction by adutting against trochanter are important. Graft must be large, stable, not to be absorbed.
2) Indications of the operation are those which satisfy the following conditions;
a) Caput femoralis is tracted as far downwards as possible.
b) “CE angle” is at least from slightly positive or minus.
c) Epiphyseal line of the head of femur is closed.
.d) Arthritic symptoms are not present remarkably. Anterior version of the neck of femur or torsion of the shaft are not present.

The author conducted experiments in order to find the staining method, to be manipulated simply, to be conducted rapidly and to be suitable for morphological investigation and discrimination of species Protozoae, and obtained results that 10% of formalin solution for fixing and dilute Giemsa liquid, 1 drop per 2 ml of phosphate buffer solution or 2 drops per 3 ml, were respectively the best ones, which will be distinguishable to demonstrate flogella, nucleus and other detailed structures of trichomonas elongata.
The technic shall be proceeded as follows;
The material and the fixing solution of 1/2 to 113 in quantity are mixed on slide glass, layed aside for 10 to 20 minutes, and spread thoroughly over the slide glass. When the circumference of the smear becomes dry, and the slide is dripped in the staining solution and kept in it for 6 hours at 37°C. Further process shall be as usual.

The clinical use of plethysmography has been evaluated by numerous workers as a good indicator of the conditions not of vascular system but of sympathetic nervous system, which innervates peripheral blood vessels. Only few physiological studies, however, have been reported up to the present.
The purpose of the present paper is to detect more delicate features of plethysmogram, to reveal physiogical factors swhcch control its mechanism, to consider these things in comparison with other sympathetic phenomenon and to discuss characters of plethysmogramh to be used.
Ten normal adults, aged from 19 to 36, were the subjects.
Photoelectric plethysmogramh and direct amplifier connected with inkwriting recorder were used.
Pulse wave were recorded from the small finger tip of right hand, and respiration, ECG and GSR were recorded simultaneously.
1) At rest, saw-toothed plethysmogram with slightly changed duration and amplitude by respiration was observed.
2) By stimulation, deflection of the bass line, shortened amplitude of the pulse ware and shortened duration of pulse wave were observed.
3) By blocking of the sympathetic nerves to the finger, enlarged amplitude of pulse wave was observed and the former two responses were eliminated, while the latter remained.
4) By applying heat to hand, enlarged amplitude of pulse wave was observed and two former responses became evident. Applying coldness resulted smaller amplitude of pulse wave and equivocal two former responses, while the latter was indifferent by changes of temperature.
5) Plethysmography is irritable to the controlling blood supply, while GSR is sensitive by the changes of temperature.
6) Direct amplifier is desirable in order to observe deflection of the base line and C-Ramplifier permits qualitative observation of pulse wave.

1) For re-examining of the problem of homogeneous distribution of red corpuscles in a counting cell, each datum observed with a Bürker-Türk's chamber was tested in two ways as follows.
First, corpuscles in 5 large squares of ruled area were counted in 480 rectangle unitareas, one of which was fourfold the size of a small square. The homogeneity of corpuscles distribution in these 5 large squares was tested “statistically”, i, e. by the χ² test of the discrepancy between the frequency distribution of these 480 data and the expected Poisson distribution of equal mean (Test I). On the other hand, the corpuscles in each large square were counted in 16 middle sized squares, one of which was sixteenfold the size of a small square. From the 5 large squares was counted consequently a datum consisting of 5 sets of 16 values. Concerning this datum the homogeneity of corpuscles-distribution among the 5 large squares way tested “Stochastically”, i, e. by a test of “homogeneityamong the means of small
samples” (Test II). As far as the distribution of red corpuscles in a countingcell is theoretically homogeneous, the data of every counting case must be “satisfactory” in the goodness of fit at Test I and “not significant” at Test II. It was found, however, in the counting with routine procedures, that one out of 2 cases which were satisfactory at Test I was significant at Test II, and that 8 out of 24 independently tried cases were significant at Test II.
2) It was found by the following experiments that the main cause of such an uneven distribution was due to the procedure of charging a counting cell.
a) Concernig the manner of charging a counting cell with diluted fluid, the experiments were divided in 2 groups: charging at one sitting (C. I . S.) and charging at two sitting or more (C. II. S.). Among 11 cases of C. II. S, 5 cases of uneven distribution in test II were observed, while among 11 cases of C. I . S., none of such cases was observed. The difference between the uneven distribution cases of two groups was significant with 0.05 level.
b) No case of the uneven distribution in Test II was observed among 18 cases of C. I . S. in which the counting cells were not filled completely with fluid, while few of such uneven distribution cases were observed among this group C. I . S, cases in which the spaces were overfilled, even if slightly, with an excess of fuid.
c) The counting was made with the same pipet and with the same cell on 20 blood samples (Experiment A). The Experiment A was divided in two groups of ten cases. Group I was made with paying no special regard to a charging conditon. Group II was made under two special charging conditions: charging the counting cell at one sitting, and with no excess of fluid. Among 10 cases of group I, 3 cases of uneven distribution in Test II were observed and each F- value (ratio between interclass variation and interclass variation) of all cases deviated remarkably from zero-point, while among 10 cases of group II, no case of such uneven distribution was observed and each F-value did not deviate significantly.
3) Five countig celles of Bürker-Türkes' type were filled successively with diluted fluid of a pipet, in accordance with the above mentioned charging procedure, and the corpuscles contained in each central large square of these cells were counted in 16 middle sized squares. The data consisting of 5 sets of 16 values counted were tested similarly as in Test II (Experiment B). This was divided in 2 groups. Group I of Experiment B consisted of 5 cases being made with paying no special regard to a charging condition and group if of the same experiment consisted of 10 cases being made under the above mentioned special charging conditions. One case of the uneven distribution was observed in group I of Experiment B, while
