Survival rates after operation for 689 gastric cancer patients were investigated, and following results were obtaind.
The patients having the tumors which are larger than egg size, infiltrate to the serous metastasis to the great omentum, mesentery, mesocolon etc, showed the lower survival rates than the patients having the tumors which are smaller than walnat size, never extend up to muscular stratum and have the limited metastasis only around stomach.
These patients having the smaller tumor than walnat size do not frequently show the specific symptoms of gastric cancer So it will be necessary to do very exect examination while gastric cancer patients will not show any specific symptoms.
Most important things for the early detection of g astric cancer are to establish the method for early diagnosis as well as to propargate the knowledge about cancer, to distribute the cancer detection center and to closely contact with the first-line medical institutes. State subsidy is to be paid for the medical expenses of gastric cancer pati ents.

The auther studied on the effects of benzene 0.15cc/kg on the EEG in cerebral neocortex, hippocampus and amygdala of intakt rabbits.
The results obtained as followed.
1) The arousal grade of EEG in neocortex, hippocampus and amygdala increases by administration of benzene. Spontaneous spindle burst in neocrtex disappeares completely.
2) The sleep pattern on the neocortex followed administration of pentobarbi tal changes to the arousal pattern by aditional administration of benzene but the righting reflex does not recover.
3) The thresholds of the arousal reaction on each activating systems for neo-, paleoand archi-cortex, including on the neocortical recuiting response, does not change after the administration of benzene.
4) The increa sing of the arousal grade of EEG in neocortex, hippocampus and amygdala followed the administration of benzene may be due to the inhibitory of the medial reticular formation.

The anthor stadied of the effects of 0.1cc/kg intravenous administration of Trichlorothlene on the cerbrebral neocortex, hippocampus and amygdala.
1) After the administration of Trichloroethyl ene the neocortical EEG pattern does not change, but the electrical activity of the limbic lobe reduces.
2) The ascending reticularactivating system for the neoeortex, and the recuiting response, may not be effected after administration of Trichloroethylene while the hypothalomus active ting system for the limbic lobe may be depresed.
3) This fact may be comfirmed by t he increase of the threshold yroduces arousal reaktion for the limbic lobe.
The decreas e af spinal reflex of normal after the administration of Trichloroethylene may be due to the infibition of lateral reticular gormation.

The results obtained as follows.
1) A administration of Trichloroethylene (Trinh.0.05cc/kg) depressed the bwave of electroethinogram, but after the repeated administration the bwava had a tendencp to shorten after by a administration of Trichloroethylene and had a tendency to prolong after the repeated administration of Trichloroethylene.
2) The amplitude of cwave had a tendency to nepressing after administration of Trichloroethylene but that hat a tendency to increasing after the repeated administration.
3) The administration of Trichloroethylene deprese more stronger the inhihitorymechanism for the Sinaps may retiona than the Sinaps of ganglion cell fayer in retinae.

Electromyographic studies on the activity of muscles of under limbs, m. rectus femoris, m. sartorius, m. biceps femoris, m. tibialis anterior, m. fibularis longus, m. gastrocnemius, m. flexor digitorum longus and m. extensor digitorum brevis during the Walking Step of dancing were made using the surface electrodes, and were analysed and compared forming into a table of quantity by the total electric output of each muscles of the pattern. In dancing 4 skilled girl students and 3 unskilled were tested. Results obtained are as follows:
1. The coefficient of correlation on the height of waves and the diminsions are extremely high.
2. The element of + and - on the height of waves in some muscles are a fairly correlative with each other. But some muscles are nearly next to impossible. So that, it is desired that the comparison will be performed on the sum of the elements of + and -, calculating the height of waves H, the frequency n, and H/n on the individual elements.
3. Walking Step has some electromyographically common patterns as follows when all persons tested. The total electrical output during Walking Step is the highest in m. tibialis anterior and m. flexor digitorum longus, and the lowest in m. rectus femoris and m. sartorius. The activity of m. tibialis anterior is especially high during the period from the lifting the right foot to its crossing with the left foot. The activity of m. flexor digitorum longus and m. gastrocnemius seems to increase gradually during the supporting period, but it is weak during the oscillating period. M. biceps femoris is especially active during the period from landing of the right tiptoe to leaving the left foot from the ground.
4. The pattern of Walking Step is somewhat different person to person, but not so remarkably different at repeated testings on the same person.
5. For the good trained girls the beginning and the end of discharges are sharper, and the daily differences of patterns are smaller than for the not trained
.6. For the trained girls the total electric output of each muscle holds the mean value, but no so for the untrained, taking higher or lower value.

An investigation was made on prenatal health condition and types of delivery of those mothers who had premature infant in the areas of Oyodo and Ikuno in Osaka.
The results obtained were as follows;
1. In those mothers who had premature infant,20% of Toxemia of pregnancy and 3% of non-obstetric diseaser were noted.
The rate of abnormal delivery was 19%
2. Prematures weighing less than 2kg were Found few in those mothers who had been healthy during pregnancy and had delivered later than 36 weeks af gestation with normal delivery.
