ジャーナル フリーFifteen years post-operative survival rate of gastric cancer cases for each metastasis, positive and negative at time of operation as reported by Masao Muto, professor of surgery at Tohoku University has been analysed.
The results are as follows:
1) Each 15 year survival rate curve for metastasis positive and negative in sem-logarithm scale is composed of two linear lines with the gradient of line 0.013 and 0.504 respectively.
2) From the above results, the author has devised a model that the patients treated by operation are classified into the three stages, that is healthy group (S1), possible relapse group (S2) and relapse group (S3), and that S1 and S2 is transferable each other but S3 is transfered from S2.
The instantaneous transition probabilities of S1→S2 and S2→S1 are 0.015 and 0.072 respectively. and the force of mortality of cancer S2→S3 is 0.430.
3) Using the above model, the survival rate of each stage is calculated as follows:
In metastasis negative group the survival rate curve of healthy group (S1) is S1=12.262e-0.013t-0.897e-0.504t and, the survival rate curve of possible relapse group (S2) is S2=0.341e-0.013t+6.094e-0.504t, Also, in metastasis positive group, the survival rate curve of healthy group (S1) is S1=12.065e-0.013t-12.052e-0.504t and the survival rate curve of possible relapse group (S2) is S2=0.335e-0.013t+81.852e-0.504t.
4) The rate of metastasis negative at time of operation is 11.4%, and the cure rate of the metastasis positive group is 10.0%.
Thus it seems that the cure rate of the operative treatment for gastric cancer is about 20.0%.抄録全体を表示PDF形式でダウンロード (670K) -

ジャーナル フリーIn order to elucidate socio-medical factors involved in the medical care system, for example the relationship between physicians and patients, or the interrelation of medical institutions, an interview survey was conducted in the period from 1961-1964 which included 2, 696 patients under internal medicine as well as those under surgery in nineteen different hospitals.
Results are summarized as follows:
1. Many of the patients, roughly 66% stated that they went to “Home doctors”. In spite of this they shifted to other physicians without consulting their “Home doctors”. This indicates a relationship which is neither binding nor obligatory.
2. Shifts to more than three different doctors were reported. These took place without the consent or approval of the “Home doctor”. The ratio of unauthorized shifts increased depending on the rising frequency of the shifts.
3. Among the surveyed hospitals the judgements of the attending doctors were that directions given to the patients for hospital admission were untimely in light of their particular ailments.
4. Following discharge from the hospital the patient often had follow up care from the out patient department at the same hospital, hence the “Home doctor” was left out of the picture.
5. Affinity of patients to their “Home doctor” appeared weak and superficial and the interrelationship among medical institutions poorly arranged. Commercialization of medical management could be a contributing factor.抄録全体を表示PDF形式でダウンロード (2940K) -

ジャーナル フリーIn our previous paper on dust aerosol it was pointed out that reconsideration should be given to the present allowable level of atmospheric contamination based on a quantitative evaluation of dust.
Following the investigations on dust aerosol in ordinary living environments, bacterial aerosol, especially hemolytic bacteria, was analysed as to its environmental medical significance.
The results are summarized as follows:
1. There were no correlations among the numbers of dust aerosol (measured with Millipore Filter), bacterial aerosol (with Millipore Filter) and fallen bacteria (by Koch's method).
2. The number of hemolytic bacteria in the air was closely related to the number of persons gathered as well as to the cold-epidemic.
It is known that hemolytic bacteria is related to humans as a carrier of bacteria in contrast to fallen bacteria by Koch's method. This fact suggests that hemolytic bacteria in the air may be a new useful indicator of atmospheric bacterial contamination in living environment.
3. Among the strains of hemolytic bacteria, staphylococcus was observed most frequently, biological characteristics of which were tested with the coagulase reaction and deoxyribonuclease reaction which are understood as being closely related to the pathogenecity of microorganisms.
4. In a cold-epidemic, coagulase-positive staphylococci were observed, but rarely in a non-cold epidemic. In contrast, deoxyribonuclease-positive staphylococci were found even in a non-cold epidemic.
These results indicate that the deoxyribonuclease reaction may be valuable for determination of the pathogenecity of staphylococci in the air.抄録全体を表示PDF形式でダウンロード (822K) -

ジャーナル フリーEach colorimetric method of fluoride analysis has the common defect of a low tolerance for interfering substances. For this reason a clean-up for water or biological samples is always necessary. The recently devised fluoride electrode is said to have no such defect. The author checked the interferences of seven metal ions to the electrode and these interferences were minimized by the use of chelating agents such as citrate. Superior reproductability in multiplicate analysis was shown compared to La-Alizarin Complexon, a solvent extraction method which is believed to be the most reliable to date. In the analysis of domestic well water in a fluoride-rich area, the figures using the electrode were always lower than those using the standard method (Zr-SPADNS). Reason for the discrepancy was analysed and the following results were obtained: The high degree of hardness of the water, i.e. the amount of Ca plus Mg ions induced an apparently higher fluoride concentration using the SPADNS method. Therefore this method appeared to be the one of choice for analysis due to it's simplicity as well as reliability.抄録全体を表示PDF形式でダウンロード (736K) -

ジャーナル フリーThinner sniffing was prevelent among High School Boys in Gunma Prefecture during 1968. Glue was used in some cases which contained a large amount of methyl alcohol and this appeared to be very hazardous to the optic nerves, lungs and bronchi.
This prevelence of boys sniffing thinner was discovered to be 3.0% by the determination of urinary hippuric acid, a toluene metabolite.
Epidemiology of thinner sniffing was the same as that of smoking, and the control of smoking would reveal the decrease of smoking as well as the decrease of thinner sniffing. The source of control should be at the Senior High School age level. One effective means of control was that parents be trustworthy and reliable in their actions. The daily lives and associated friendships of the children should be well supervised. Well informed teachers and participation in sports was found not to be helpful in exercising control in these fields.抄録全体を表示PDF形式でダウンロード (644K)
