An infusion apparatus which can control very minute volume easily and precisely has been wanted by pediatricians and neonatal surgeons. In order to fascillitate the strict coun'ing and controlling of minimal infusion speed (200cc to 500cc per day or more, 40 to 120 drops per cc), the author modified the ordinary type dripper and made a new one of extremely small drip.
Any amount of fluid, if it is more than 200cc per day, can be infused at the rate of more than 10 drops per minute.
The mechanism of the dripper is very simple as shown in Fig. 4: the fluid to be infused drips through the siliconized point of the dripper. Since the outside of the point is water-repellent, the size of drip formed is much smaller compared with one through nonsiliconized set. Siliconisation is eaily repeated in case the water-repellency is diminished or lost.

1) Bacteriostatic effects of various antibiotics on Döderlein's bacillus. It is said that Döderlein bacillus (D bacillus) plays the leading part in autopurification of normal female's vagina. And it has been an unsolved problem for every gynaecologist to find how D bacillus will be influenced by various kind of antibiotics which are widely used by the physicians. We also desire to select such drugs which will act exclusively on pathogenic bacteria but will have no influence on D bacillus.
From this viewpoint a comparative study was made on the bacteriostatic effects of various kinds of antibiotics on D bacillus.
Procedure
In this experiment 4 strains of bacteria and 12 kinds of the drugs were used. The method with filter paper discs was adopted. The Bacteriostatic effects of each drug was examined by measuring the size of the growth inhibition circle of the D bacillus.
Results
According to the strains little differences were recognized. First, Penicillin showed the strongest effect, second Erythromycin and Leucomycin showed about the same effects. Third, Chloramphenicol. Forth, Novobiocin, Streptomycin, Oxytetracycline, Tetracycline at d Oleandomycin. Fifth, Kanamycin showed the weakest bacteriostatic effects. Sixth and last, Colistin and Trichomycin showed no bacteriostatic effects.
2) Vaginal application of Kanamycin and Ddderlein's bacillus. From the above described experiments it was assumed by us that although Kanamycin (K) has a wide antibacteriostatic spectrum it has little influence cn D bacillus. So after applying K a clinical vaginel examination was performed.
Procedure
The patients who mainly complain of leukorrhea with nonspecific vaginitis and/cr cervicitis were supplied with K vaginal suppositories (cacao oil including K 25mg) and a solution of D bacillus culture (number of bacilli 36×10⁸). Thereafter the presence or absence of leukorrhea and pruritus in the patients, was determined.
The vaginal pH was measured. And microscopic examination of the vaginal smears and cultures of vaginal canal was done and candida was observed. As a control a combination of penicillin vaginal tablet (P tablet) and D bacillus solution were used.
Results
The application of K suppositories only 2 or 3 times resulted in disappearance or decrease of leukorrhea, subjective effectiveness, little influence on D bacillus and improvement of vaginal purification to a certain extent.
While application of D bacillus solution combined with K suppository for 2 times showed more distinct vaginal settlement of D bacillus than in the group which only K suppositories were used. Besides, combined treatment was effective both subjectively and objectively.
In the group in which P tablets were combined with D bacillus solution, no vaginal settlement of D bacillus was recognized. And miscellaneous bacteria perished and the vagina became almost aseptic.
From the above mentioned results we might conclude that the combination of K suppository and D bacillus are most effective in treatment of nonspecific vaginitis and cervicitis and we are able to expect quick normalization of bacterial vaginal flora by this treatment.

Some remarks of the Ashibumi-Test on healthy persons were obtained and their physiological value limits were investigated. When we added healthy persons with weak rotary stimuli or caloric stimuli, there were distinct reaction of the Ashibumi-Test. Furthermore, a quite contrary effect was noted on the direction of deviation which was induced by both cold and warm caloric stimuli.
We confirmed a fact that the head position was influenced with the deviation of the Ashibumi-Test, but not so strongly. We also found that the following fact: the direction of deviation wasreversed a certain number of minutes after pouring water 20cc and 30°C on the patient who had the Ashibumi-Test for a long time.
This made us assume that there is a close relation between the endolymphatic flow and the course of the Ashibumi-Test.

From December 1960 to March 1931 at the Saitama National Hospital both in and outpatients with acute diseases of the upper respiratory tract and lung were clinically and serologically studied and the patients were observed according to their occupation such as non-medical employees, nurses and nursing school students.
Results
1) The outbreak season of influenza in this area around the Saitama National Hospital was coincidental with the spread of this disease in the whole country.
2) Among the nurses, there were several cases of primary atypical pneumonia and B type influenza.
3) Those who had mass outbreak of the influenza belonged to B type, And these occurences were found limited to certain rooms of the dormitory

Of 419 operated cases with gastroduodenal ulcer from 1949 to 1960 experienced in the Clinical Surgery of the Chiba National Hospital, we had statistical observations especially on the aged patients who were more than sixty years old. Simultaneously studies in the literature were also made.
Results
1) The incident of frequency was relatively low among the aged and it proved to be 7.8 per cent of total cases.
2) The operative mortality was as high as 6.6 per cent.
3) There was no significant difference in the incidence of perforation, however, there was a close relationship between increased operative mortality and perforation.
4) Regarding the period from onset to operation one fourth of the cases was less than 6 months; indicating that relatively short period was more common than the long term.
5) The most chief frequent complaint was in the upper stomache following hematemesis, melena and vomiting.
6) In regard to hemorrhage during the course hematemesis and melena were relatively frequent, however, results from the occult blood test showed no significant difference.
7) With regard to gastric acidity, most cases were hyperacidic and a significant increase of anacidic cases were noted.
8) Concerning the location of ulcer, it showed that the ratio of the proximal site to distal one was 1:2; with larger number in the proximal one. In size of lucers there was no significant difference.
