| 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. |

| Title Alternative | Enumeration of T-cells in peripheral blood as well as in joint fluid from patients with rheumatoid arthritis (RA) and the effect of cyclophosphamide |
| 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. |

| Title Alternative | A useful procedure for taking photograph of resected specimens |
| FullText URL | pitsr_047_001_003.pdf |
| Author | Noishiki, Yasuharu| |
| Abstract | Histochemical, biochemical, and electron microscopic investigations on resected specimen have expanded in almost exponential manner in the past ten years and taking photograph of the specimens is also of importance for the examination of them. The specimens are, however, damaged during the time of taking photograph by various factors such as heat, dryness, light etc. For the investigations of this kind, the most important requirement for preservation of protoplasmic structure is to interrupt the dynamic process of the cell as prompt as possible and to stabilize the structure with a minimum of change. To prevent the damage of the specimens during the time of taking photograph, the following procedure is proposed: The specimen is dipped into cold saline solution, phosphate buffer, or cacodylate buffer. as soon as possible after operation. Photographic procedure is carried out upon the specimen dipped into the solution. By this procedure, the specimens can be protected from being damaged by heating and drying. Furthermore, the specimen can be preserved in its original shape due to the aid of buoyancy. This procedure has an another advantage : The photograph is in principle free from halation on the surface of the specimens. Thus, the proposed procedure is very useful for taking photograph of resected specimens in general. |

| Title Alternative | Prevalence of periCardial effusion in patients with rheumatoid arthritis -An echocardiographic study- |
| FullText URL | pitsr_048_049_054.pdf |
| Author | Ishii, Hirofumi| Domyo, Michihiro| Tanaka, Juntaro| Takasugi, Kiyoshi| |
| Abstract | In order to determine the incidence of pericardial effusion in rheumatoid arthritis (RA), echocardiographic studies were performed on patients with classical or definite RA as determined by ARA criteria, none of whom showed any clinical cardiac symptoms at the time of examination. Of 50 RA patients studied so far, fifteen (30%) showed evidence of posterior pericardial effusion, as recorded on the strip charts. Additionally, in one full-blown case of rheumatoid vasculitis, massive accumulation of pericardial fluid was demonstrable. Compared to those without pericardial effusion, patients shown to have pericardial fluid tended to have decreased RBC, Hct, Hgb, serum protein concentration and increased ESR. The statistical difference between the two groups was significant (P<0.005). The most conspicuous difference between the two, however, was noted in the degree of hypoalbuminemia that is more profound in the effusion positive group (P<0.005). The possible cause of fluid retention in the pericardial cavity in RA was briefly discussed. |

| Title Alternative | A case of SLE with non-erosive joint deformity -Jaccoud's type arthropathy- |
| FullText URL | 048_043_048.pdf |
| Author | Tanaka, Juntaro| Domyo, Michihiro| Takasugi, Kiyoshi| Irino, Shozo| Morinaga, Hiroshi| |
| Abstract | A case of SLE in a twenty-eight year old woman, who had polyarthritis with non-erosive joint deformity, was reported. Differential diagnosis in this case included (1) rheumatoid arthritis (2) postrheumatic fever arthritis (Jaccoud's arthritis) and (3) the overlap syndrome between SLE and rheumatoid arthritis. Laboratory findings on this patient and review on literature, however, strongly suggested that this lady had been suffering from Jaccoud's type arthropathy of SLE. Corticosteroid therapy was initiated and the clinical course of the patient thereafter has been more than favorable. |

| Title Alternative | Determination of boron in thermal waters by emission spectrophotometry using "Spectraspan" |
| FullText URL | pitsr_048_035_041.pdf |
| Author | Mifune, Masaaki| Aoki, Hiroko| Tetsumoto, Junko| Furuno, Katsushi| Morinaga, Hiroshi| |
| Abstract | A plasma emission spectrophotometer "Spectraspan" (low power d. c. plasma arc, operating on argon) was evaluated for boron determination in thermal waters. The influence of acids (hydrochloric, nitric and sulfuric acids) and several metallic ions (Na(+). K(+), Mg(2+). Ca(2+)) on emission intensity was studied. There was a linear relationship between emission intensity and boron content from 0 to 500 mg/l. Boron in thermal waters was easily determined by standard addition method. Precision. coefficient of variance and recoveries of known amount of boron added to the sample for 11 repricate analyses were 0.12μg/ml, 2.02%, 95.0-101.7%, respectively. Boron content of 27 thermal waters in the Sanin district was determined. and the highest B content in the sample waters were 8.8 mg/l (Tottori spa) in Tottori Prefecture and 14.6-25.0 mg/l (the thermal springs at the foot of Mt. Sanbe. a non-active quaternary volcano) in Shimane Prefecture. The relationships between B content and water temperature, B content and pH value were not recognized. Significantly positive correlationship was observed between Band Li contents. |

| Title Alternative | Determination of copper and zinc in synovial fluid by atomic absorption spectrophotometry |
| FullText URL | pitsr_048_013_023.pdf |
| Author | Furuno, Katsushi| |
| Abstract | Copper (Cu) and zinc (Zn) in synovial fluids of 52 patients with rheumatoid arthritis (RA) and of 53 patients with osteoarthritis (OA) were determined using a HITACHI MODEL 207 atomic absorption spectrophotometer. Standard solution of Cu and Zn were 50μg, 100μg, 200μg and 300μg per 100 ml 20 v/v % glycerine containing 0.01 N-HCl. To 0.5ml synovial fluid, 50 units of hyaluronidase was added and then the mixture were incubated for 20 minutes at 37℃. Synovial fluid treated with hyaluronidase and standard solution 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 recoder. The mean recovery rate of Cu and Zn in synovial fluids were 102.0% and 101.9%. By this method the concentrations of Cu and Zn in 52 RA (12 males, 40 females) were 97.6±29.0 (S.D.) μg/100 ml and 83.9±40.1 (S.D.) μg/100 ml ; 97.3±27.1 (S.D.)μg/100 ml, 78.7±29.9 (S.D.) μg /100 ml in 12males and 97.7±29.5 (S.D.) μg/100 ml, 85.5±42.6 (S.D.) μg /100 ml in 40 females respectively. The concentrations of Cu and Zn in 53 OA (14 males, 39 females) were 46.9±14.5 (S.D.) μg/100 ml and 40.8±14.3 (S.D.) μg/100 ml; 47.3±9.7 (S.D.) JLg/100 ml, 45.1±19.0 (S.D.) μg/ 100 ml in 14 males and 46.8±15.8 (S.D.) μg/100 ml, 39.3±11.8 (S.D.) μg/100 ml in 39 females respectively. No sex differences of Cu and Zn values were observed in both RA and OA. In patients with RA, concentrations of Cu and Zn in synovial fluids were signifcantly higher than in OA in both sexes. There were positive correlation between the concentrations of Cu and Zn in 105 patients (RA and OA, r=0.74, p<0.01) , in 52 RA (r=0.54, p<0.01), in 53 OA (r=0.81, p<0.01). In patients with RA, there were no correlation between stage and concentrations of Cu and Zn in synovial fluids. |

| Title Alternative | Microprobe analysis of Japanese standard rocks JB-1 and JG-1 |
| FullText URL | pitsr_048_007_011.pdf |
| Author | Sakiyama, Toru| Kagami, Hiroo| Tazaki, Koichi| Asada, Hitoshi| |
| Abstract | The Japanese standard rocks JB-1 and JG-1 are analyzed with the electron microprobe. The glass chips are prepared by direct fusion method by Nicholls (1974). Slight modifications of Nicholls' method for fusion temperature and preparation of rock powder give good results. Production of homogeneous glass chips needs fusion for 20 seconds at temperature 1500 to 1600℃ for basalt (JB-1) and 1800 to 1900℃ for granodiorite (JG-1). Very fine rock powder less than 10μm is preferable. |

| Title Alternative | Application of the ultra-thin section method for high resolution electron microscopy of clay minerals |
| FullText URL | pitsr_048_001_006.pdf |
| Author | Tazaki, Kazue| Noishiki, Yasuharu| |
| Abstract | Clay mineral specimen for electron microscopy have usually been prepared by air-drying of a small drop of the suspensoin on a microgrid. The suspension method is, however, not always preferable for the observation of lattice images of clay minerals because of their preferred orientation in the air-drying process. The present writers proved that the embedding method is excellent in preservation of the nonorientated part of the crystal than that of susp, ension method. The interstratified kaolin/montmorillonite which was collected from clay bed at Itoigawa, Niigata prefecture is dehydrated progressively replacing H(2)O by ethanol, propylene oxide and Epon mixture solution and is lastly embedded in Epon 812. Ultra-thin sections are prepared with an LKB Ultratome, and are examined in a JEM-100C type electron microscope at an accelerating voltage of 100 kV. High resolution electron micrographs show lattice images reflecting irregular layer structures of kaolin and montmorillonite. Clear layer structure and lattice images can be well observed from everywhere of ultra-thin section of clay mineral (Fig. 1). Lattice images of 4.5 and 10A spacings can be observed in Fig. 2. Microstructures show some differences in spacing which emerged from combination of dehydrated montmorillonite and kaolin layers (Fig. 3). |
