| FullText URL | 046_061_070.pdf |
| Author | Aoki, Hiroko| |
| Abstract | Uric acid was measured in serum and urine of the ambulant and hospitalized patients with various disorders including gout. in Misasa-Branch Hospital of Okayama University Medical School from January 1975 to December 1976. Serum and urine samples were obtained from 283 males and 260 females, and from 2 males respectively. The results are as follws; (1) Uric acid in males was 1.4 mg/100mf higher than in females. (2) Uric acid in males decreased with ages, showing two peaks between 15 and19 , and between 35 and 44 years old. (3) Uric acid in females showed low levels between third and fifth decades and increased thereafter with ages. (4) There were many fatty subjects among the patients with gout. (5) An increase in total daily excretion of urinary uric acid was observed concomitantly with increased daily urine volume. (6) Periodical fluctuations of uric acid in serum and other clinical findings were show in several cases of gout, who had been controlled in MisasaBranch Hospital for several years. |

| Title Alternative | Hydrogen and oxygen isotopic ratios of thermal and mineral springs in Arima area |
| FullText URL | pitsr_043_015_028.pdf |

| Abstract | Saline waters of thermal and mineral springs in Arima area, at Takarazuka, and in Ishibotoke area of Kawachinagano City indicate wide ranges of δD and δ(18)O values (Table 1). Excellent linearity exists between the δD and δ(18)O values (Fig. 1) and between the δ(18)O value and the chloride concentration (Fig. 2). These facts as well as the chemical evidence of the previous investigators strongly support the view that Arima springs are admixtures of a single deep brine and local ground water (TSURUMAKI, 1964). The deep brine may have the δ(18)O value of +8.0～+8.5‰, the δD value of -25～-30‰, and the chloride concentration of 1.20～1.25 eq/l, which were estimated from the water of the maximum salinity so far reported. Because the thermal and mineral springs in Arima area closely associate with the upper Cretaceous granitic rocks, and the estimated δ(18)O value of the deep brine is similar to a value of water in isotopic equilibrium with those granitic rocks at 500～600℃, the deep brine of Arima might have been the magmatic water of those granitic rocks. The mineral springs at Takarazuka and in Ishibotoke area also show the similar linearity among Cl(-), δ(18)O and δD to those in Arima area. Therefore it is assumed that the mineral springs at Takarazuka may be of the same origin as that in Arima area, and the mineral springs in Ishibotoke area might have been the fluid associated with Ryoke metamorphic rocks. Alternatively, the deep brine in Arima area may be isotopically and chemically similar to the saline formation waters in Illinois basin (GRAF et al., 1966). The high δD values and salinities of those formation waters were attributed to the isotopic and chemical fractionation during the passage of water through sediments. The deep brine in Arima area may be genetically similar to those saline formation waters. If such a saline water could have formed in Osaka basin, it is not surprising to find out the similar brines at Arima and Ishibotoke which are the northwestern and southeastern rims of the basin, respectively. At the present, it cannot be answered which of these two models is more probable. Further studies on other saline springs fluid inclusions of Cretaceous granitic rocks may be useful in order to solve this problem. |

| Title Alternative | Determination of manganese in serum by atomic absorption spectrophotometry |
| FullText URL | pitser_046_037_043.pdf |
| Author | Furuno, Katsushi| |
| Abstract | The manganese (Mn) concentrations in serum of 40 healthy controls (9 males and 31 females), and of 26 patients with rheumatoid arthritis (4males and 22 females) were determined using a HITACHI MODEL 207 atomic absorption spectrophotometer. Wavelength of Mn determination was setted at 2795 A. Flow rate of acetylene was setted at 3.0 l/min and lamp current was setted at 10 rnA. The serum samples were ashed by IPC MODEL 1003plasma machine, and dissolved in 3N-HCl and evapolate on the hot plate, and redissolved in constant volume of 0.1 N-HCl. These sample solution were aspirated directly into the burner. Mn levels in serum were estimated by standard curve. The mean recoverry rate of ashedsample solution was 100.1%, and that of serum by ashing process was 101.6%. The serum Mn levels in 40 healthy controls and 26 patients with rheumatoid arthritis were 2.19 ± 0.34 (S.D.), 3.04 ± 1.01 (S.D.) μg/100ml respectively. The serum Mn levels in rheumatoid arthritis were significantly higher than healthy control levels (p<0.001). In 10 of 26 cases (38%) with rheumatoid arthritis, the serum Mn levels were shown to be above the upper limit of 5% rejection limit of healthy controls. |

| Title Alternative | Determination of copper and zinc in serum by atomic absorption spectrophotometry |
| FullText URL | pitser_046_025_035.pdf |
| Author | Furuno, Katsushi| |
| Abstract | Copper (Cu) and Zinc (Zn) in serum of 113 healthy controls (43 males and 70 females) and of 68 patients with rheumatoid arthritis (19 males and 49 females) were determined using a HITACHI MODEL 207 atomic absorption spectrophotometer. Wavelength and lamps current of Cu and Zn were setted at 3247 A, 2139 A, and 10mA, 9mA respectively. Flow rate of acetylene and air were setted at 3.0 l/min, and 13.0 l/min. The stock standard solutions of Cu and Zn were 0.5 mg, 1.0mg, 2.0mg and 3.0mg per 100mE in 0.01 N·HCl. For working standard solutions, these stock standard solutions were diluted to 50μg/100ml. 100μg/100ml, 200μg/100ml and 300μg/100ml with 20% glycerine. Serum and working standard so· lutions of Cu and Zn were diluted five fold with deionized distillation water, then aspirated directly into the burner. The relative absorbance was expressed as scale reading by a HITACHI MODEL QPD-54 recorder. Various acids and other elements had few influences on the determi· nations of Cu and Zn. The mean recovery rate of Cu and Zn in serum were 100.5% and 100.8% respectively. By this method, the levels of Cu and Zn in healthy controls were 103.0±14.5 (S.D.), 116.2±18.6 (S.D.) μg/100ml in males and 108.7±19.6 (S. D.), 110.3±14.7 (S.D.) μg/100ml in females respectively. No sex difference were observed. The ratio of Cu and Zn (Cu/Zn ratio) of healthy controls were 0.89±0.17 (S. D.) in males and O.99±0.25 in (S.D.) females. The sex differrences of Cu/Zn ratio were statistically significant (p<0.05). The levels of Cu and Zn in rheumatoid arthritis were 141.7±25.2 (S.D.). 89.1±14.5 (S.D.) /-Lg/100 mP and 154.l±29.7 (S.D.), 86.7±18.1 (S.D.) μg/100ml in females respectively. No sex differren· ces were observed. The Cu/Zn ratio were 1.64±0.43 (S.D.) in males and 1.82±0.48 (S.D.) in females, wich showed no sex differrences. In patients with rheumatoid arthritis, serum Cu levels were significantly higher (P<0.001) and serum Zn levels were significantly lower (P<0.001) than in healthy controls in both sexes. The Cu/Zn ratio were significantly higher (P<0.001) rheumatoid arthritis than in controls. The serum Cu in 13 of 19 males (68%), and 30 of 49 females (61 %), with rheumatoid arthritis were shown to be above the upper limit of 5% rejection limit in healthy controls. The serum Zn in 3 of 19 males (16%), and in 24 of 49 (47%) with rheumatoid arthritis were shown to be below the lower limit 5% rejection limit in healthy controIs. The Cu/Zn ratio in rheumatoid arthritis, in 14 of 19 males (74%), and in 35 of 49 females (71%) were shown to be above the upper limit of 5% rejection limit in healthy of males and females. So, differences in Cu/Zn ratio between healthy controls and rheumatoid arthritis were proved to be more pronounced. |

| Title Alternative | Circulatory changes in rheumatoid fingers as estimated by thermography and photoelectric plethysmography |
| FullText URL | pitser_046_015_023.pdf |
| Author | Ohta, Takamasa| Tokioka, Masaaki| Takasugi, Kiyoshi| |
| Abstract | In an attempt to evaluate circulatory changes in patients with rheumatoid arthritis (RA), 20 patients with classical or definite RA as determined by ARA criteria and twenty healthy volunteers serving as control were randomly selected. None of the patients showed the clinical signs suggesting Raynaud's phenomenon. Thermograms as well as photoelectric plethysmograms were obtained solely from the right middle finger tip of each examinee. The whole hand was then immersed in the cold (10℃) water and kept there for one minute. After wiping away the wet hand with a dry towel very gently, we followed the sequential changes of the tempe· rature of the third finger tip and the period of time necessary for the tip to return to the original temperature prior to the cold water immersion was measured and expressed as 'return time' in minute. Before exposure to the cold, the mean values of temperature of the finger tips between the two groups were not significantly different. As opposed to the normal pattern in which one can find the warmest point at the finger tip and which was more frequently found in the control group of the current study, a type in which the distal part of the finger was much cooler than the proximal area (so-called 'distal cold type') was observed in 8 RA patients, whereas only four demonstrated this pattern in the control group. After brief exposure to the cold, eight out of 20 rheumatoid patients showed much prolonged return time (longer than 20 minutes), while only three of 20 controls remained with prolonged cool periphery, The difference between the two, however, was not statistically significant. Studies of the digital plethysmograph revealed that 70% of all the rheumatoids showed abnormal patterns: sclerotic and monophasic waves were discovered in 55% of the patients. In contrast, seventy percent of the normal control demonstra· ted normal wave pattern. Although the significant difference was not noted, the mean height of the systolic peak of the plethysmograph derived from the rheumatoid group tended to be much reduced, suggesting the reduced blood volume at the finger tips. Six RA patients and 13 normals who showed normal plethysmographic pattern before immersion in the cold water, demonstrated rapid return to the original temperature. Only in one normal control with a normal wave pattern, prolonged return time was observed, although the height of the systolic peak of the plethysmogram in this particular case was well within normal limit. Digital circulatory disturbance, however, was strongly suspected in eight RA patients with severely prolonged return time, They all showed abnormal wave patterns of the plethysmogram, including 2 cases with peripheral plateau wave, Markedly reduced heights of the systolic peaks were also demonstrated in all. Further elaborate studies including digital arteriography were indicated to implicate any organic change in the digital vessels, such as digital arteritis in RA first reported by Bywaters in 1957. |

| Title Alternative | A case of cancer in the gastric remnant |
| FullText URL | pitser_046_011_014.pdf |
| Author | Noishiki, Yasuharu| Nakahara, Yasuhiro| |
| Abstract | This is a report of cancer of the stomach encountered in a 71-year-old man who admitted to the hospital with complain of epigastralgia. He had undergo a two third gastrectomy with gastroduodenostomy 24 years before because of severe gastritis. For several years he had ambulatory treatment for diabetes mellitus, which was under good control. Laboratory examination revealed that red-cell count was 4,800,000, white-cell count 11,500 ; hemoglobin was 12.7gr. per 100ml, hematocrit 49.5 per cent. Total serum protein was 8.2%. The stool was positive for occult blood and the urine negative for protein. X-ray studies in barium filled stomach in upright position revealed a filling defect in the lessor curvature side. In the prone and supine double contrast studies, a lesion was visualized of irregular outline with marked surface unevenness. Endoscopically, a rough tumor resembling Borrman Type III cancer was found near the stoma on the anterior wall of gastric remnant. Marginal blending and convergency of the folds showing sudden cessation around the ulcer were recognized as well. These findings led the authors to the diagnosis of the cancer developing in the gastric remnant and total gastrectomy with esophagojejunostomia was performed. Reports of cancer in the gastric remnant detected more than 20 years after the first operation are so small in number. |

| Title Alternative | Fundamental study of post operative intestinal adhesion -Findings on early stage of peritoneal inflammation by ultraviolet irradiation- |
| FullText URL | pitser_046_001_009.pdf |
| Author | Noishiki, Yasuharu| |
| Abstract | Early process of peritoneal inflammation on rat by ultraviolet irradiation was studied histologically and scanning electron microscopic· ally. After 1 minute irradiation of ultraviolet, minimal exudation on mesothelium was found. After 15 minutes irradiation, microvillies on mesothelium were covered with exudate. After 20 minutes, fibrin fibers appeared on intact mesothelium. Though the fibers wafted in exudate, the fibers could be cleared up by irrigation of saline. After 30 minutes, white and red cells appeared on the nest of fibrin fibers. After 45 minutes, edema came out at subserosal layer. After 1 hour, mesothelium was covered with fibrin fibers, white and red cells. But the coated fur could be washed off by jet irrigation of saline and intact mesothelium benearth the fur appeared. These results indicate that washing a peritoneal cavity by saline after abdominal operation is of practical value to prevent a intestinal adhesion due to post operative intestinal inflammation. Inflammatory changes of intestinal mesothlium was clearly demonstrated by scanning electron microscope and these observations revealed that scanning electron microscope was very useful for the study of inflammation which occured on the surfaces of organs. |

| Title Alternative | The treatment of rheumatoid arthritis with D-penicillamine. Preliminary report |
| FullText URL | pitsr_047_069_075.pdf |
| Author | Ishii, Hirofumi| Takasugi, Kiyoshi| Kitayama, Minoru| Morinaga, Hiroshi| |
| Abstract | Twenty patients with classical or definite rheumatoid arthritis were treated with D-Penicillamine. Favorable responses were observed in 75% of the patients. Significant improvement in clinical parameters, such as ESR, CRP, titers of rheumatoid factor and so forth, was noticed in twenty weeks of treatment. Withdrawal from penicillamine treatment was necessitated in four patients because of adverse reactions to the drug. Untoward effects included skin rash (most frequent), pruritis and loss of taste. From this preliminary study we presume that in earlier cases in which rheumatoid lesions may be reversible, more favorable clinical effects would be expected from this agent. |

| Title Alternative | Stable isotope study of the hotsprings and volcanoes of Hokkaido, Japan |
| FullText URL | pitsr_047_055_067.pdf |
| Author | Matsubaya, Osamu| Sakai, Hitoshi| Ueda, Akira| Tsutsumi, Makoto| Kusakabe, Minoru| Sasaki, Akira| |
| Abstract | Stable isotope ratios of hydrogen, oxygen, carbon and sulfur of precipitation, thermal and mineral waters, and volcanic gases were measured. The isotopic data combined with chemical and geological information were discussed in terms of origin and evolution of the hotsprings and volcanic gases. The hotsprings along the Uchiura Bay, Oshima Peninsula are mostly near-neutral NaCl-type thermal water and may be divided into three groups : (1) thermal waters isotopically similar to the precipitation of this area, (2) those similar in D/H to the local meteoric waters but enriched by 2 to 3‰ in (18)O compared to the latter, and (3) those enriched significantly in both D and (18)O relative to the local meteoric waters. The first and second types of thermal water probably form from local meteoric water which percolates through "Green Tuff" formations and acquires dissolved chemicals from them. However, high salt concentration and the oxygen isotope shift (thesecond type) may imply that the NaCl-type water of volcanic origin might be involved. On the other hand, the waters of the third group can be explained by mixing of modern sea water into the second type thermal water (in case of Yachigashira) or by incorporation of fossil sea water of Tertiary origin into modern meteoric water (Nigorigawa). Except for Esan, Noboribetsu and Atosanupuri volcanic systems, waters from all the hotsprings and volcanic fumaroles associated with Quaternary volcanic rocks are meteoric in origin. Thermal waters at Esan, Noboribetsu and Atosanupuri have δD = -30～-50 and δ(18)O = -1～+ 3‰ and are enriched in D and (18)O relative to local meteoric water of the respective area. The origin of these waters and the mechanism (s) controlling the isotope ratios could not be made clear by the present study. Interesting is the finding that at Esan, Noboribetsu and Atosanupuri, thermal waters are enriched in D and (18)O relative to near-by fumarolic gases. The enrichment factor is 18 to 26‰ for hydrogen and 4 to 6‰ for oxygen, implying that more than one stages of liquidvapor separation are taking place in underground hydrothermal systems. |

| FullText URL | pitsr_047_041_048.pdf |
| Author | Tokioka, Masaaki| Takasugi, Kiyoshi| |
| Abstract | Gradient centrifugation was quite useful in obtaining "mononuclear" cell fractions from synovial fluids derived from patients with rheumatoid arthritis. The ratio of lymphocytes to monocytoid cells was similar to that seen in peripheral blood. Prior treatment of the fluid with hyaluronidase was found to be necessary to obtain a satisfactory yield of the cells. Sheep erythrocyte rosette-forming lymphocytes (T-cells) were studied in 18 paired samples of synovial fluid and blood in RA and 15 control blood samples from normal persons were also examined. In the paired synovial fluid and blood samples from the RA patients, the mean percentages of the T-cells were 56.6 and 47.1 respectively and the difference was statistically significant (0.01 |

| Title Alternative | Petrological study of the Okutsu granodioritic mass in the northern part of Okayama Prefecture. Japan - Part 1 Geology and petrography |
| FullText URL | pitsr_047_033_040.pdf |
| Author | Sakiyama, Tooru| |
| Abstract | The Late Mesozoic granitic rocks have been studied in the Okutsu area, northern Okayama Prefecture. Main portion of the area is occupied by the Okutsu granodioritic mass. It consists of mediumgrained hornblende-biotite granodiorite, mediumgrained biotite granite, fine-grained biotite granite, and aplitic granite in the succeeding order of intrusion. Contacts between these rock-types are generally gradational and An-contents of both core and margin of the plagioclase progressively decrease with increasing acidity of the rocks. These facts indicate a cognate origin of various rock-types of this mass. The Kamisaibara granite, rather uniform coarse-grained hornblende-biotite granite, occurs in large batholith. It is inferred petrographically that the Kamisaibara granite is a member of the Ningy6,t6ge granite widely distributed on the north of this area. Field evidence suggests that the Ningyo-toge granite was intruded by the Okutsu granodioritic mass. |

| Title Alternative | The involvement of ear and throat in rheumatoid arthritis I. Hearing in patients with rheumatoid arthritis |
| FullText URL | 047_005_024.pdf |
| Author | Oda, Rei| |
| Abstract | Since Copeman's report on patients with hearing impairment as "rheumatoid otoarthritis?" has introduced, there have been a few reports on hearing impairment in patients with rheumatoid arthritis such as Goodwill et al. and Djupesland et aI. in European countries. On the contrary in our country there is no reference in association with hearing impairment of rheumatoid arthritis in rheumatic or otological literatures. An audiometric survey was carried out in 76 patients admitted in the Misasa branch hospital of Okayama university school of medicine on the classical or definite rheumatoid arthritis. Patients were excluded from the series if they had scarred or perforated tympanic membrane and history of otorrhea. Thus 67 patients have come to study. As control group, 15 healthy persons in hearing for each ten years, 15-24, 25-34, 35-44, 45-54, 55-64, and over 60 years, were selected and as a physiological hearing limit, rejection limit of hearingloss in dB. was made. Among 67 patients, 111 ears had hearingloss within the above mentioned rejection limit. In 23 ears, hearingloss in dB. were partial or as a whole out of the limit. They have all air-bone-conduction gap. After inflation of Eustachien tube, in most of them air conduction ability showed nearly the same level of bone conduction. In three cases even by inflation, airconduction level did not move. In one case the left side had effusion liquid and its RAreaction was positive. TwO of the former patients and the one whose effusion liquid had positive RA-test followed up for about 3 years. In the former two cases, hearing impairment got worse little by little and recovery by inflation was not seen. On both cases Gelle's test was positive. In the latter hearing impairment slowly got worse. This had lasted for about two months and had recoverd. In the se four cases heairng impairment was probably related to the rheumatoid arthritis and no other causes could be found. |
