| Title Alternative | Application of the ultra-thin section method for high resolution electron microscopy of clay minerals |
| FullText URL | pitsr_048_001_006.pdf |

| 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). |

| Title Alternative | Microprobe analysis of Japanese standard rocks JB-1 and JG-1 |
| FullText URL | pitsr_048_007_011.pdf |

| 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 | 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 | 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 | A case of SLE with non-erosive joint deformity -Jaccoud's type arthropathy- |
| FullText URL | 048_043_048.pdf |

| 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 | 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. |
