In the period of five years and nine months from April 1969 to December 1974, thirtynine cases of advanced undifferentiated stomach cacinoma had been examined by double contrast Barium-enema ...examination. Of these, some infiltrating patterns of the large bowel were discovered in twenty-nine cases and forty-nine lesions. These abnormalities included. (1) irregularity of the bowel wall (marginal serration) (2) disapperance of the haustration (3) narrowing of the bowel canal (4) poor distensibility of the bowel (5) nodularity of the mucosa (6) gradual transition to the normal bowel Summary 1) Radiological classification of colonic involvement for the most part corresponded to the macroscopic finding in the laparotomied and autopsied cases. II) The transverse and the sigmoid colon may be involved frequently. Ulcerations were shown in all cases with rectal involvement. III) Cases with colonic involvement have to be given a serious consideration of their operability.
Experiments were carried out with hardened coconut oil to find the correlation between crystal growth and hydrolysis of esterifird lower fatty acid at lower temperature. 1) A.V. showed practically no ...change, both in hardened and non-hardened oils, when stored in anhydrous state, and there was no difference in the values due to storage temperature. When the oil was saturated with vapor, the values increased in the order of those stored 15 and 5°C, and the tendency was especially marked in hardened coconut oil stored at 15°C. 2) Methyl ester of hardened coconut oil and those dissolved in ethanol, n-hexane and benzen did not show rise in A.V. values even when stored at a low temperature. 3) The fraction obtained by molecular distillation showed less change, even when stored at 5°C, than the original hardened coconut oil. The fact that A.V. was higher in Fraction 2 than in Fraction 1, containing larger amount of lower acids, indicated that when molecules of a same size were collected, more impacted intermolecular space should be presumably produced. This was borne by the fact that electron microscopic observation showed a smooth surface although there were fine single crystals.
Pure coconut oil of the same lot was divided into samples in the stages of crude oil, purified, semi-hardened, and hardened state, and each sample was stored at -20, 5, 15 and 30°C for 6 months. ...Values of A.V., P.O.V. and Co.V. were measured in every month, and their correlation with crystal growth was examined by electron microscopy observation. The same experiments were also carried out on a mixure of (a) hardened coconut oil added with hardened beef tallow or cotton seed oil and (b) hardened beef tallow mixed with non-hardened coconut oil or butter fat. 1) The values of A.V. rose in those stored at 15 and 5, in that order, and especially in the hardened oil. Practically no change was seen in those stored at -20 and 30°C. P.O.V. was zero throughout the test period, while Co.V. showed higher value with increasing storage temperature and less hardening. 2) Hardened coconut oil mixed with hardened beef tallow showed marked rise in A.V. while that mixed with cotton seed oil showed no change in A.V. values. When hardened beef tallow was mixed with non-hardened coconut oil, rise of A.V. value was about the same as that of hardened coconut oil. 3) Electron microscopic observation of hardened coconut oil showed that the roughness of crystal surface increased in the order of storage temperature of 15, 5, 30 and -20°C, which corresponded to the order of rise in A.V. values. The crystal surface of the oil stored at 5°C showed the presence of whiskers. In the oil stored at 15°C, single crystal had shown great growth and there was a space between that and the next single crystal. If a vapor is present in that space, absorptive reaction might occur in the singular face of the crystal. 4) The surface was smooth in non-hardened coconut oil, and liquid glyceride was found to occupy the spaces between single crystals. 5) In the hardened coconut oil mixed with hardened beef tallow, the crystal surface became rough, while the sample of hardened coconut oil mixed with cotton seed oil was similar to the hardened coconut oil stored at -20°C.
In this study, we analysed 2, 080 tuberculosis patients hospitalized in 18 sanatoria and chest hospitals in Aichi prefecture on September 30, 1977. The results were summarized as follows: 1) The ...duration of admission of patients was long, for instance, the number of patients staying for more than 1 year were 886 (42.6%), more than 3 years were 456 (21.9%), and more than 5 years were 309 (14.9%). 2) Concerning bacilli discharge in sputum, 1, 398 patients (67.2%) excreted tubercle bacilli during their stay, and 480 patients (23.1%) within 3 months before the survey. 3) Among 480 positive patients, 249 were failure cases who continued to excrete tubercle bacilli inspite of staying in hospital for more than 1 year (so-called “Chronics”). “Chronics” were seen in 12.0% of all patients, and in 28.1% of those staying for more than 1 year. 4) Approximately 70% of patients staying for less than 3 months were cavitary and/or sputum positive cases on admission. 5) Main reasons of admission to hospitals were to conduct initial chemotherapy effectively and to isolate infectious cases. 6) Main reasons of continuation of hospitalization for longer period were persistent excretion oftubercle bacilli, respiratory insufficiency and complications.
