Abstract The effect of pH of water on the measurement of oxygen isotopic ratio by means of CO(2)-H(2)O isotopic exchange technique was studied. In this study, a new type of reaction vessel was used (Fig. 1). The reaction time for equilibration using this new reaction vessel was nearly equal to that in the previous study (Fig. 2). The oxygen isotopic ratios of each two samples of pH 2, 4, 7, 8, 9, and 10 were measured. There is no significant difference between the observed δ(18)O values of these samples (Table 1). Therefore it is concluded that the effect of pH of water needs not to be taken into account on the measurement of oxygen isotopic ratio by means of CO(2)-H(2)O isotopic exchange technique.

Title Alternative Absorption of Medium-chain triglyceride (MCT) in isolated intestinal loops of dog and its effect upon the lipids of serum aud adipose tissue
FullText URL pitsr_041_049_056.pdf
Author Kotakemori, Michiaki|
Abstract The absorption of medium chain triglyceride (MCT) has been investigated with intestinal loop of dog without both bile and pancreatic juce. On optimal state, the average coefficient of fat absorption was 78.1±7.4%. The use of medium chain triglyceride diet for 4 weeks in dogs had some effecton lipids of serum and adipose tissue but minimal change on clinical evidence was found. There was a prompt reduction in the proportion of arachidonic acid and a sustained increase in the proportion of oleic acid and linoleic acid in serum lipid. Analysis on lipids of adipose tissue showed prompt reduction in the proportion of oleic acid and linoleic acid. Neither clinical evidence nor side effect induced with medium chain triglyceride was found.

Title Alternative Studies on chrysotherapy in rheumatoid arthritis, III. Gold determination by the atomic absorption spectrophotometry
FullText URL 041_035_048.pdf
Author Takahashi, Kazue|
Abstract The gold concentration in serum, synovial fluid and urine has been determined using a HITACHI MODEL 207 atomic absorption spectrophotometer. Flow rate of acetylene was setted at 2.0l/min. and lamp current was setted at 8mA. The samples were pretreated by the determination of gold. Serum was diluted with deionized water by two to ten-fold. To O.2ml. of synoival fluid 50units/ml of hyaluronidase was added and then incubated for 20 minutes at 37℃. This sample was then treated the procedure for serum given previously. Urine was treated using the modification method of Christions procedure. The recovery rates with gold sodium thiomalate in serum, synovial fluid and urine were 99.9%, 102.5% and 93.6% respectively. When gold sodium thiomalate was injected in rabbits, the maximum serum gold level was attained 1 hour after injection and then gradually decreased at about 50% of the maximum level 24 hours after injection. In the observations of changes in the gold levels in the serum of patients with rheumatoid arthritis after injection of gold sodium thiomalate and gold thioglucose, its peak level after gold thioglucose injection tended to be slightly lower as compared with the same amount of gold sodium thiomalate injection. In those patients who had been given 300 mg. or more of gold salt-preparation, one additional injection of 25 mg. of gold salt could attain the gold level of around 200μg/100ml, in serum a week later, and this level was very nearly the same with that after 3-4 days of one additional injection of 1Omg. of gold salt. The amount of gold excreted in the urine varied from patient to patient, and the mean excretion rates of gold sodium thiomalate and gold thioglucose in the urine within 24 hours after intramuscular administralion were 9.8% and 6.5% respectively. The simple, rapid and accurate method for analysis in biological specimens using atomic absorption spectrophotometer would offer one of the excellent measures in the clinical management of patients with rheumatoid arthritis.

Title Alternative A subsequent report on the new McKinney type mass spectrometer in the Institute for Thermal Spring Research, Okayama University
FullText URL pitsr_041_003_007.pdf
Author Matsubaya, Osamu|
Abstract Since the installation in April 1970, the McKinney type mass spectrometer has maintained a good condition and about 5000 isotopic analyses of oxygen, carbon and sulfer has been cerried out so far. The ion source filament was changed to spiral one from single wire. Consequently three times sensitivity and the longer life of filament were obtained. Gradual changes in the ratio of potential divider (β) and the sensitivity (|△ E(0)(2)|/E(0)(1)) for the difference of β have been observed (Table 1). Because these changes are opposite in trend but similar in degree, it is supposed that these changes are caused by decrease of feed-back resister value in the balancing system. Although there remain some problems in the corrections for the difference in observed isotopic tatio between two cases that a same CO(2) is fed to ion source from the ST side of inlet system on the one hand and from the X side on the another, the reproducibility of the measurement of isotopic ratio for long period is about ±O.1‰ (Table 2, Fig. 1). δ(18)O values of standard waters, MSA-1 and MSA-2, measured during a period from May to Dec. 1970 and in Sep. 1971 yielded good agreements implying the reproducibility of the measurement to be constant (Table 3). Both calculated δ(18)O values relative to a given sample based on each observed δ(18)O value relative to two different samples agreed each other. It is concluded that the linearity of observed a-value holds over a range of 30‰ (Table 4).

Title Alternative On the measurement of oxygen and carbon isotopic ratios of carbonates
FullText URL pitsr_041_009_012.pdf
Author Watanabe, Makoto| Matsubaya, Osamu|
Abstract Oxygen and carbon isotopic ratios of two working standards of our laboratory and three other standards were measured by McCrea's technique and the new McKINNEY type mass spectrometer in this Institute. The reproducibility of δ(13)C measurement is about ±0.2‰. Some systematic differences in δ(18)O values were observed among the three measurements in Apr.-May, July, and Aug., 1971. Because these systematic differences are supposed to be caused by the imperfection in the processes of decomposition of carbonates by phosphoric acid, the reproducibility of δ(18)O measurement may be ±O.2‰ in most cases. The calibrations of our working standard, CK-13, against the PDB standard were carried out on the assumption that δ(18)O and δ(13)C of CK-13 are -1.75‰ and +O.54‰ relative to PDB, respectively. The accuracy of these calibrations is about ±O.2‰ as shown by the interlaboratory comparison of some standards (Table 3). The δ(18)O values of the two working standards relative to PDB are independently recalculated relative to SMOW based on the two assumptions (Table 4). One of which is that a standard water MSA-2 is -8.20‰ relative to SMOW, and the other is that the δ(18)O of CK-13 is -1.75‰ relative to PDB. The results of both calculations agree within 0.4‰.

Title Alternative Report of a case of severe mechanical joundice -Successfully treated by jejuno-hepatic ducts anastomoses
FullText URL 041_057_062.pdf
Author Noishiki, Yasuharu| Kotakemori, Michiaki| Komoto, Yoshiaki| Nakahara, Yasuhiro|
Abstract Jejuno hepatic ducts anastomoses were successfully performed by carefull managements. Because of dense adhesion at hilus of liver, around the gall bladder and choledocus, dissection of common duct, cystic duct, hepatic ducts and even gall bladder was very difficult anatomically. Resecting a inflammatory granulative tumor, including gall bladder, choledocus, lesser omentum and hepatocluodenal ligament en mass, we found that only very short hepatic ducts with inflammatory granulation tissue were remained open. Reconstruction of biliary passages was done using Roux. Y. method with loop jejunum. It needed very carefull procedure to avoid suture failure, ascending infection (cholangitis) and postoperative stenoses at the site of the anastomoses. The anastomoses were performed using atraumatic 3-0 Tefdek ; interrupted and each big bite of duct wall together with surrounding thickend granulative tissue, in order to keep capillary blood supply effective and to minimize the anastomotic trauma which were very important for wound healing. Patient is healthy, enjoying his normal life and his liver function tests are within normal range, 1 1/2 years postoperatively.

Title Alternative Esophagus hiatal hernia with special reference to the early stage
FullText URL pitsr_041_063_068.pdf
Author Noishiki, Yasuharu| Komoto, Yoshiaki| Nakahara, Yasuhiro|
Abstract In the aged, hiatal hernia should be recognized as it has developed; it develops progressively. Special attention should be given to the early stage of hiatal hernia from the genetic point of view. Like other organs in the aged, aging changes around a hiatus are inevitable; relaxing of esophageal diaphragmatic ligament and weakening of muscle power of diaphragmatic vertebral part move on with age. After all, valve structure at hiatus, Goubaroff's valve, is so weakened its function and in the stomach, "His angle" is so widened, that the stomach becomes wedge shaped against the hiatus. The more the pressure in the stomach increases, the larger the wedge shapes. Under these conditions, when the abdominal pressure rises by the acts of coughing or defecation, hiatus may be widened and the wedge may be pushed into the hiatus. There are no strong valve and or ligament enough to keep the wedge part of stomach in peritoneal cavity. In the stomach, the pressure of the expelling meal is equal to that of the widening wedge. On the other hand, in the peritoneal cavity, pressure produced by the act of defecation is equal to that of ejecting the wedge through hiatus. These are self-evident from the Pascal's principle. Hiatal hernia is produced under these conditions. We, therefore, should call the attention to the early genetic stage of hiatal hernia. In Japan, hiatal hernia has been recognized when it gets larger and fixes out of the peritoneal cavity. But in the early stage, it also must be noted as hiatal hernia.
