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.

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.

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.

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).

Title Alternative Ammonium content of Archean rocks of the Superior Province
FullText URL pitsr_049_007_013.pdf
Author Honma, Hiroji| Schwarcz Henry P.|
Abstract Ammonium contents were determined for clastic sediments and associated volcanic rocks of the Kirkland Lake area, Abitibi greenstone- granite belt and metamorphic, migmatitic and granitic rocks of the Ear Falls-Dryden area, English River gneiss-granite belt. The NH(4) centents of Archean volcanic rocks (2700~2710m.y.) are very low (0~6 ppm) and immature argillites have also low contents of NH(4) (27~43ppm). On the other hand, a black shale from the Timiskaming Group (2100m.y.) are rich in graphite and pyrite and contain much NH4 (130ppm), providing a firm evidence of relatively abundant presence of an Archean biota compared with a sparcity of morphological record of Archean fossils. The NH(4) content of the rock mentioned above is about a third of those of the upper Proterozoic sediments and it remains to be established whether it reflects the abrupt break in the evolution of life near the Archean-Proterozoic boundary or not. A considerable amount of NH(4) is inherited by highly metamorphic pelitic gneisses and there may be a possibility for indirect prospection of early life by a study of NH(4) in highly metamorphic rocks of the early Archean. It was also found that the gneissic granitoid has much higher content of NH(4) than the post· kinematic massive granitoid.

Title Alternative Excretion of radon in expired air after bathing and drinking of radioactive hot spring water at Misasa Spa
FullText URL 049_001_006.pdf
Author Furuno, Katsushi|
Abstract Radon (Rn) contents in expired air after bathing, exposure in hot-air room and drinking of Misasa radioactive hot spring water were determined using an ionization chamber equiped with vibrating reed electrometer. The results were as follows; 1. Rn Contents in the indoor and outdoor air of Misasa spa were in the range of 0.5-1.0 pCi/ℓ and 0.4-0.7 pCi/ℓ. 2. Rn contents in the expired air of persons living at Misasa spa area and none spa area were 0.4-0.9 pCi/ℓ, 0.6±0.2 (S.D.) pCi/ℓ and 0.1-0.9 pCi/ℓ, 0.5±0.2 (S.D.) pCi/ℓ respectively and no difference of Rn contents was observed in both groups. 3. The highest Rn contents in the expired air of subjects bathed in radioactive hot spring (Rn ; 58.0×10(-10) Ci/kg, watre temp. : 41±1℃.) were immediately after bathing, and the values were 10.8-25.5 pCi/ℓ (bathing for 5 min.), 16.0-27.9 pCi/ℓ (bathing for 10 min.) and 38.8-59.3 pCi/ℓ (bathing for 15 min.) respectively. Rn contents in expired air were reduced to about 1.0 pCi/ℓ during 120-180 min. after bathing. The longer the bathing time and the younger the subjects, the higher Rn contents in the expired air. The biological half-life of Rn in the expired air of subjects after bathing was 42-43 min. 4. The highest Rn contents in the expired air of subjects exposed in hot-air room (Rn in air; 54.3pCi/ℓ, air temp. : 37-38℃., humidity: 40%, staying for 15 min.), and the values were 4.9-7.8 pCi/ℓ, and gradually reduced to about 1.0 pCi/ℓ during 120 min. The bioligical half-life of Rn in the expired air after leaving the hot-air room was 43 min. 5. Rn contents in the expired air of subjects immediately after drinking of radioactive spring water (Rn contents: 596.8×10(-10) Ci/kg, 500mℓ), were the highest, and the value were 28.0-101.5 pCi/ℓ, and reduced to about 1.0pCi/ℓ during 180 min. after drinking. The biological half-life of Rn in the expired air was 40 min.

Author Mifune, Masaaki|
Abstract Lithium in serum was determined by a plasma emissionspectrophotometer "Spectraspan" (low power d.c. plasma are, operating on argon). The opitimum condition for ashing of serum by low temperature was studied. The influences of hydrochloric acid and several metallic ions (Na, K, Mg, Ca) on emission intensity were examined. There was a linear relationship between emission intensity and lithium content from 0 to 10μg/ml. Lithum in serum was easily determined by standard addition method. Precision, coefficient of variance and recovery of known amount of lithium added to the sample for 12 replicate analyses were 0.093μg/ml, 1.85%, 99-104%, respectively. Significantly positive correlationship was observed between emission spectrophotometry using spectraspan and atomic absoption spectrophotometry.

Abstract Two oxygens of which δ(18)O is +28.83 and -79.57‰, respectively, were converted into carbon dioxide by means of both an external heating method and a Daylight's method where a graphite rod was heated by concentration of light from a slide projecter lamp on the graphite rod, and the δ(18)O of carbon dioxides obtained in the two methods were compared to each other. Except for data affected by memory of the previous sample, the averages in the external heating method were +28.85 and -79.56‰, respectively, and quite consistent with the averages in the Daylight's method, that were +28.81 and -79.67‰, respectively. This concludes that no oxygen isotope exchange occurs between the sample gas and the quartz glass of reaction tube in the external heating method. There is no significant difference in the results in four externally heated carbon furnaces, whereas the memory of previous samples was apparently observed within each furnaces. This memory was larger in the furnaces containing a used graphite rod (Nos. 3 and 4) than those containing new one (Nos. 1 and 2), and also more significant for smaller samples (Run 4 in No. 3). However, if the reaction tube was baked out at a higher temperature (750℃) than the reaction temperature (700℃) before reaction, the memory was mostly eliminated (Run 8 in No.3).

Abstract Radon(Rn) contents in the air of radioactive spring areas were determined using an ionization chamber equipped with vibrating reed electrometer. The results were as follows: (1) Rn contents in the outdoor air at spa areas of Misasa. Sekigane and Togoo were 0.7 ± 0.4 pCi/l. 0.6±0.3pCi/l and 0.5±0.2 pCi/l respectively. Rn contents in the air both at Misasa and at Sekigane were significantly higher than at none spa area of Kurayoshi city (0.3±0.2pCi/l). (2) Rn contents in the outdoor air at Misasa spa tend to increase from June to September in the year. (3) In usual rooms where spring water is not used. Rn contens in the air were below 1.0 pCi/l. Rn contents in the air of facilities using spring water were determined; peloid therapy room: 2.0±0.4 pCi/l, usual bath rooms: 6.3±1.3 pCi/l (before the bathing). 21.8±2.1 pCi/l (immediately after bathing), Hubbard bath room: 6.7±0.3 pCi/l (before the bubbling), 143.4±69.8 pCi/l (during the bubbling), exercise pool room : 4.3±0.3 pCi/l (before the exercise). 7.4 ± 0.8 pCi/l (during the exercise) and drinking hall: 30.0~47.0 pCi/l respectively.
