Follow-up observations of the gastric ulcer of 658 patients revealed 135 cases of the recurrence. These cases were studied from the points of view as shown below.
(1) Relation between recurrence rate of the ulcer and age and sexe.,
(2) Anatomical relations of the site between the recurrent lesions and the previous ulcers, and period of the remission.
(3) What types of the lesion tendod to recur, and what findings were characteristic endo scopically on the time of recurrence?
(4) Directions toward which the recurrent ulcers appeared and histological characters of the previous ulcers.

Bacterial replacements are an important cause of prevention from recovery from urinary tract infections.
For discovering the cause, 42 cases of urinary tract infection which have been treated for recent 2 years and bacterial replacements were occured more than three times were studied clinically and bacteriologically.
1. There were many male cases in the sixth and seventh decade.
2. The underlying illness was found in 90% and 63% of them received surgery for prostate-hypertrophy.
3. The patients accompanying the other illness were found in 62%, in which the illnesses of the cardiovascular system and diabetes mellitus are note worthy.
4. on the biochemical examinations of hosts, the cases indicated lower AG ratio were 42%, for which the increase of globulin may have an important role to do.
5. The bacterial replacements were frequently found on the cases who had obstruction of urogenital system by operations, used catheters long after the operations or had the system changed with tumor, etc. But in younger ages there were a few cases without those conditions.
6. The bacterial genera on the bacterial replacement were the same as that on urinary tract infections, especially on cross infections.
7. On the order of the bacterial replacement on those genera there was no rule, but there were relatively more mix-infection, especially mixed with bacilli and cocci.
8. There was no relationship between the sorts of used antibiotics and the replacing bacterial genera. When antibiotics were not used, there were less bacterial replacement.
9. There are still more unknown factors about the cause of the bacterial replacement on the cases without the mechaaism of retrograde urinary infection, about the cause that bacteria are cultured again and again despite of the sensitive antibiotics are used, and about the other true cause of the bacterial replacement.

From results of questionaire, it was found that kits were easily adopted at every laboratory in hospital.
With regard to LDH, LAP, β-lipoprotein and uric acid, each kits were examined on the same serum of 58 normal men and women.
Normal range was calculated from the values of result. The normal range by us was compared with the normal range indicated in kits.
The nomlal range indicated in LAP kits ran paralell with that by us, but the normal range indicated in LDH kits did not.
The normal range by us was lower than the normal range indicated in β-lipoprotein kits, but opposite findings were noted in case of uric acid kits.
These findings showed that the normal range did not always run paralell with the normal range by us.
From these results the normal range should be examined before new kits were adopted.

Since 1964, the standardization of an aesthesia record, available for statistical investigation has been studied by the members of joint study unit of anaesthesiology, for the purpose of the determination of the efficiency on the anaesthetic methods, agents and soon by means of the data obtained from large mass of patient group. The anaesthesia record is made up of two pieces. One is a thick paper for keeping at the anaesthesia department as punched card, the other is a thin paper for being filed into the patient record. The former has 124 holes at the edge of the paper. The results concerning about 14141 cases expedenced in 14 hospitals were reported by Dr. Yamashita at the 22nd Medical convention of national hospitals and sanatoriums in 1967.
Recently, according to the fast progress of electronics, the techniques of digital electronic computers are becoming useful not only for the scientific fields but also for the management of every kind of business.
The medical use of electronic computer is as follows:
1) Information Retrival
2) Signalanalysis (Diagnosis and Mgnitoring)
3) Medical research
4) Simulation
5) For use of medical business
In order to avoid the hazardness of punched cards above mentioned and to get more accurate results, We planned statistical investigation by using electroaic computers. Mark card is one of the ways to input the data to electronic computer. This card, size 187×82mm., is marked by pencil and canberead optically by mark card reader of the new type. Fourty two lines are available in one sheet of markcard. Patient number, date, age, sek, fisk, dept., duration of anaesthesia and operation, premedication, techniques and agents of anaesthesia, pre-during and postoperative complications, site of operation, position, and cause of death are laid out in the mark card designed by us. For this research, we are making the plan to use HITAC 8030 computer equipped at National cancer center, and are going to make program now.
The research of this joint study unit of anaesthesiology started on 1st Jan. 1971, and the results will be reported at the 26th Medical convention of national hospitals and sanatoriums.

Before coming to our department, a continuous steroid therapy had been performed to a 26-year-old woman during the past 3 years, and to a 18-year-old girl during the past 5 months.
These cases showed the following bilateral findings: disturbances of visualacuity and field, increased ocular rigidity, optic atrophy, and excavation of the disc.
Surgery played an important role of improving such abnormal findings.
Very cautious consideration should be paid for a steroid therapy.

While hare-lip and cleft palate are most common malformation, but transverse facial cleft is very rare.
Transverse facial cleftis also known as cleft of cheek, transverse cheek cleft or macrostomia etc.
One of our cases is three months old and the other is 21-year-old female.

Leiomyosarcoma limited to the small intestine is extremely rare. Our case is unique in that it presented with an abdominal abscess due to leiomyosarcoma of the small intestine.
A 58-year-old man was hospitalized with the chief complaint of an abdominal tumor. Roentgenography after ingestion of barium showed the dislocation of the small intestine and the colon due to tumor with air-fluid level. At surgery, an abdominal abscess was found in the lower abdominal region and a drainage was performed. Three months later, the patient underwent second laparotomy. There was a large tumor mass, 15×15.5×5cm in size, arising from jejunum. Resection of the tumor was done. Central necrosis, having no connection with jejunum, was found inside the resected-tumor. Microscopic sections revealed leiomyosarcoma.
When seen at the end of two years, the patient was asymptomatic.
