1) When we use medical spectrometer we have to consider two factors; primarily the γ-ray efficiency occuring inside of Nal crystal and secondarily the γ-ray change which occurs from thyroid glands to NaI crystal.
2) Radioiodine intravenous injection will, within a few seconds-25 minutes, give a more stable and higher value, And in this case the dose administered and the range of the measurement will be necessary to note.
3) The curve of the radioiodine uptake on the patient with postgastrectomy, as compared with the normal person, will have rapid raise, while the curve on the patient of gastroptosis will have a longer time to get a higher value.
4) The speed of the uptake on the anti-thyroid drug administered case, such as mercasol, is slow and upon reaching its maximum value it becomes relatively stable.
5) The time that thyroid glands absorb radioiodine is variable; intravenous injection a few seconds, solution per as 20 minutes and capsule more than 40 minutes.
6) There is a mutual relation between the curve of uptaken radioiodine and the uptake value of thyroid glands, and also with the weight of thyroid glands.
7) It is also impossible to make diagnosis of the thyroid glandular diseases from the curves of uptaken radioiodine, however, we were more or less able to make interpretaion at the range of the measurement; 500-2, 000cpm as a constant time up to 5, and 5-200cpm as a constant time up to 10.

Eleven cases or prostatomegaly were administered therapy using 100mg of Kativ (vitamin K₃ solution by injection) and 75mg of analgetic Kativ (vitamin K₄ solution), and the expected results were obtained except in one case. Individual differences were found among the therapeutic effects. Among cases of ishemia 4 cases of spontaneous micturition were noted by 3 to 6 injections of VKa, while 2 cases required 24 and 52 injections of VK₃ and VK₄ respectively for the purpose.
To remove the urinary disturbance 6 cases were administered VK₃ and VK₄ 9 to 21 times, while 5 cases were medicated with these substances 45 to 62 times. Meanwhile, before the adenoma diminished to the size of a small egg, 2 cases were medicated with VKa 16 to 20 times, 1 case VK₃ and VK₄ 25 and 10 times respectively, and 4 cases VKa 45 to 76 times, indicating a difference in the speed of effect.
Roentgenograms showed to reduction in size of tumor in 2 cases.
Each of 2 cases had indications of relapse 1 year and two years after the therapy was completed.
Fifty injections of VKa is considered to be a adequate for the necessary dosage.
However, in order to prevent relapse it is advisable to continue 2 injections of VK₃ per week even after the therapy is completed.

Streptomycin-dependent mutants of a Mycobacterium Jucho have been suggested to have an increased permeability to sulfur ions and to have no changed permeability to phosphate in the absence of streptomycin. In addition, the mutants do not exhibit cord formation in the absence of streptomycin. Ii is suggested that the mutants may have a change of cell surface character in the absence of streptomycin.
Streptomycin-dependent mutants show a decrease in picric acid reduction ability and a slow growth rate (the generation time of the mutants is about twice as long as that of sensitive cells). The mutants have a higher metabolic activity for malate than for glucose unlike the sensitive cells.

1) The Rate of Occurance of Homologous Serum Hepatitis.
Observations of homologous serum hepatitis with jaundice were made in 27 national hospitals and 46 national sanatoria in Japan.
The number of the patients with the disease described above treated at the sanatoria were one in 1951, 6 in '52, 23 in '53, 63 in '54, 248 in '55 and 205 in '56, totaling 550. While the number of the patient with infectious hepatitis observed at the national hospitals was 254 during the year of 1955.
The mortality is 2.46 with the serum hepatitis and 4.796 with the infectious hepatitis.
2) Morbidity of Serum Hepatitis
Out of 7, 638 patients 370 blood recipients were found to have serum hepatitis, indicating 4.8% of the morbidity. And out of 6, 031 patients with pulmonary tuberculosis 307 blood recipients (5.1%) were found to have hepatitis, while out of 1, 372 non-tubercular patients we found 59 (4.3%) who were suffering from hepatitis in addition to their original diseases, This indicated that the former had a higher morbidity than that of the latter.
3) Some Findings of Serum F epatitis
The number of the patients was 419 male and 131 female and the largest number of patients were in their twenties, In most cases 1, 000-1, 500cc of blood was obtained. These were stored blood from the blood bank, fresh blood Plasma, serum and their combinations, The number of patients who received stored blood from the blood bank was 358 and this was the largest number, It is evident that lately we have much more opportunity to use stored blood, however, we are not able to tell that the occurrence of jaundice is more frequent with stored blood rather than with fresh blood.
In regard to the period of the jaundice outbreak after the transfusion, it is indicated that 80% of the patients lay in from one to three months, 36 patients lay within 30 days and 13 patients lay in over 180 days.
4) Search for Carrier
There were 14 carrier donors. A donor who caused more than two patients with serum hepatitis was diagnosed as a carrier
Explanation of Figures
(A), (B) or (C), is the sign of the donor and (1), (2) or (3) etc, is the recipient, (A) (B) shows that the recipients received blood of the donor (A) (9, 15) shows the date that blood was collected.
1 or 2 etc, is the sign of a recipient suffering from jaundice.
(A) or (B) etc. is the sign of the carrier donor.
(-) indicated no history of jaundice.
Figure 1
There were four donors (A), (B), (C) and (D) who previously had supplied blood to a recipient (1) who later had jaundice. The donor (A) also supplied his blood to the other four recipients (2), (3), (4) and (5) The recipient (2) also suffered from jaundice, The donor (B), (C) or (D) supplied their blood to several other recipients respectively, but none of them suffered from jaundice, Accordingly we regarded the donor (A) as a carrier.
Since recipient (1) and (2) were given blood from donor (A) on 20 August and 15 September, these days were decided as the date of receiving blood, so 27 days were recognized as the date that infectious agents were kept by the two recipients, And donors (A), (B), (C) and (D) have no history of jaundice.
Fig. 2, Fig. 3 and Fig. 4 indicate that donor is the carrier, while Fig. 5 indicates that donor (A) and donor (B) are the carriers, Fig. 6 shows the carriers are whether donor (A) or (B) or both of them. Fig. 7 shows the carrier is unable to determine.
An investigation was made to know the period of time that the fourteen carriers held the infectious agents with them individually and it was found as from 23 days to 252 days.
