The author made measurement of the distribution of scattered radiation and the radiation dosage received by several exposed portions of the roentgenoscopists and the nurses assisting before and after the improvement of protecting devices of the roentgenoscopic table. A ratemeter was used for the former and pocket dosimeter and film badge for the latter.
Results
1. During the roentgenoscopy before improvement a large amount of scattered radiation was measured, and in some places more than 1, 000mr/hr were reached near the position of the roentgenoscopists and the nurses assisting.
2. After the improvement scattered radiation decreased markedly.
3. A considerable ration leakage was measured around the X-ray tube vessel, and on the tube there were some places which presented 500mr/hour of dosage.
4. In some places the scattered radiation from the roentgenoscopic table and the patients were protected by means of metal parts of the roentgenoscopic table.
5. After the improvement the radiation dosage received by roentgenoscopists and nurses assisting decreased from bout one fiftieth to one sixtieth, therefore the purpose of improvement was achieved. But it is so dangerous to insert a hand behind the fluorescent screen to palpate patient's body, that it is nonesense to improve the protecting devices, if the roentgenoscopists do not pay attention to the above mentioned

After report No. 1 with the same experimental set, the author made the above titled experiments. In 15 adults dogs, the white cell count, white cell differentials Platelets count, coagulation time and bleeding times were measured. In 4 instances crystalloid solutions were used. In 5 instances glucose solution was used. And in 6 cases colloidal solution was used.
Results
White cell count decreased sharply in the experiments where crystalloid, glucose and glycoalgin solution was used for the replacement. While in the replacement experiments with dexstran and plasgen, this decrease was temporary and then returned to the pre-experimental value and finally increased, In the experiment with blood replacement, an initial dacrease was noticed but it was slight.
In all instances the differentials of WBC neutrophils and young cells increased while eosinophils, monocytes and lymphocytes decreased.
Erythroblasts were demonstrated in the instances where crystalloid, giycoalgin and blood were used for replacement.
Platelets were decreased in all instances.
Coagluation time wars decreased in the experiment with crystalloid replacement, In the case with glucose solution this decrease was also found but was a temporary phenomenon then it returned to the original value.
In the experiments with glycoalgin replacement, after the amount of blood depletion reached 40ml/kg dog's body weight, a prolongation of coagulation time was observed. In dextran and blood replaced dogs coagulation time was shortened.
Bleeding time was shortened in crystalloid replacement experiments after the removal of blood reached 10-20ml/kg, however, when the amount of blood reached 40ml/kg then the prolongation of bleeding time was noted.
In the glucose replacement experiments, when the blood loss reached 40ml/kg, there was shortening of the bleeding time, Mild prolongation was noted in glycoalgin replaced animals where bleeding amounted to 10-40ml/kg.
When blood was used for the purpose of replacement, bleeding time stayed normal until the withdrawn blood amount reached 60ml/kg when a prolongation of bleeding time started to appear.

Previously using frogs, cats, etc, their lethal doses have been measured for the biological assay of digitalis. Recently pigeons are generally used for them. Measuring lethal doses in pigeons to some known digitalis preparations such as digitoxin, lanatoside c,
g-strophanthin, Asystin, 3-acetyl strophanthidin, and 16-acetyl digitalinum verum (a newly produced cardiac glycoside) were examined as to potency, the rate of onset and disappearance of action and the rate of the absorption from the gastrointestinal tract.
Method:
1. In most cases etherized pigeons were used.
2. Intravenously small amounts of digitalis preparations were injected at every 2.5min, 5min., 10min, or 20min, till the animal died of cardioplegia, and thereby the potency and the rates of onset and disappearance of the drug was observed.
3. Three to 24 hours after the intravenous administration of a half of 10min, lethal dose which was determined at the above experiments, then the same drug was injected intravenously at intervals of 10min, till the animals death and thereby the detoxification grade was observed in each preparation.
4. Three hours after administration of a half of 10min, lethal dose which was determined in the first experiment, then the same drug was injected intravenously every 10min. till death. Lethal doses were determined by the oral administration only.
In these ways the absorption rate from the gastrointestinal tract was observed in each preparation.
Results:
1. Digitoxin: The rates of onset and disappearance of the action were the slowest of the drugs examined, The absorption from the gastrointestinal tract was remarkably easy.
2. Lanatosid C: The rates of onset and disappearance of action were slowest except for digitoxin. However, absorption was not easy.
3. Asystin: The rate of onset of action was fast but the disappearance is not so slow.

Recently the development of antibiotics gave great improvement in the treatment of the various kind of the pulmonary suppuration, The author made clinical observations on inpatients with pulmonary suppuration at the Nagano National Sanatorium.
Symptoms varied depending upon the types of disease, circumstances of onset of the disease, character of the sputum, and process of the lesions.
The author found that these variations were caused by combinations of the infecting germs, And the author found it necessary to observe the relationship between the clinical symptoms and the germs.
From this standpoint the author observed a) each clinical findings, b) appearance rate of the germ group and c) resistance of the each group of germs toward the drug.

We classified three types of TB-bacilli disappearance in sputum of chemotherapically treated patients whose sputum had been free from bacilli for 6 months or more, They are abrupt-, intermediate-, and lax-types.
These three types evidently have a correlation with sex distinction, chemotherapy, and types of the disease. However, they seem to have more or less a relationship to chemotherapy anamnesis.
Especially, considerably they also seem to be connected with the improvements of the chest x-ray and the red cell sedimentation rate.

On 1, 170 patients with far advanced chronic pulmonary tuberculosis, the author investigated (1) etiology, . (2) process, and (3) treatment method with chemotherapy. It reveals that the progress of treatment method, with chemotherapy causes a decrease of appearance rate of far advanced chronic pulmonary tuberculosis. For that purpose a comparison was made available: the period from 1953 up to recent when we are able to use so-called combination treatment, such as SM and PAS or SM, PAS and INHD and the period from 1959 to 1952 we were using so-called monotreatmant; the treatment by SM only. The rate of appearance of far advanced chronic pulmonary tuberculosis was indicated to be less in the former.
At the same time other unfavorable factors were found, Comparatively a large number of the patients were either far advanced or in addition they were drug resistent, Some were at home too long, some were out-patients without adequate therapy. And everywhere in Japan the purchase of antituberculous medicine is not under good control.
These seems to be some of the sources of the etiology of patients with far advanced pulmonary tuberculosis.
The author also experienced the use of a new method for patients with far advan ced puhnonary tuberculosis who seemed hard to cure with the chemotherapeuticc agents such as INHD or SM. Expecting to improve the function in the host, depressed by tuberculous toxic substances, Orotic Acid, Panthotenic Acid, and Thioctic Acid were applied in addition to the chemotherapeutic agents.
This combined method seemed to be effective not only to improve the liver function but also the blood picture and the body weight.

A survey was made of blind people living in Kyoto-Prefecture.
Population in this prefecture is 1, 967, 000 and the number of blind is 1946. The author applied the classification method of blindness of the U. S. A. and Canada. The vision under 0.04 is determined as blind.
Results
Table 1 shows etiology of the blind. The most numerous number of blindness are caused by the undetermined or not specified causes, Prenatal origin and infection is in due order, They are also divided from the standpoint of site and affected type of blindness in which diseases of eyeball are the most frequent and then diseases of cornea, and optic nerve are in due order.
Table 2 and Table 3 show classifications of blindness by sex, Table 4 is the classification of single blindness, In the Table 5 number of the blind is showed upon its age. Table 6 shows analysis of the occupation of the blind people, Fifty-two% of them are jobless and 35% of them are engaging in the business as “masseur”.
Table 7 shows occupational classification of the blind people whose one eye is blind while the other has amblyopia. Table 8 indicates numbers of cases who by surgical treatment are expected to have better vision, In this group about 200 cases have keratoplasia.
