| 抄録 | 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. |

| 抄録 | 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. |

| タイトル（別表記） | The involvement of ear and throat in rheumatoid arthritis I. Hearing in patients with rheumatoid arthritis |

| 抄録 | 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. |

| タイトル（別表記） | A useful procedure for taking photograph of resected specimens |
| フルテキストURL | pitsr_047_001_003.pdf |
| 著者 | 野一色 泰晴| |
| 抄録 | 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. |

| 抄録 | 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. |

| 抄録 | 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. |

| タイトル（別表記） | Application of the ultra-thin section method for high resolution electron microscopy of clay minerals |
| フルテキストURL | pitsr_048_001_006.pdf |
| 著者 | 田崎 和江| 野一色 泰晴| |
| 抄録 | 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). |

| 著者 | 古野 勝志| |
| 抄録 | 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. |

| タイトル（別表記） | No occcurrence of the oxygen isotope exchange with quartz glass of reaction tube through the conversion of oxygen into carbon dioxide in an externally heated carbon furnace |
| フルテキストURL | pitsr_050_041_042.pdf |
| 著者 | 松葉谷 治| |
| 抄録 | 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). |

| 抄録 | 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. |

| タイトル（別表記） | Experimental study of sulfur isotope exchange between S0(4)(2-) and H(2)S (aqueous) at 400℃ and 1000 bars water pressure |

| 抄録 | Experimental procedures used in this study are the same as those developed by Sakai and Dickson (1978). 0.005 M Na(2)S(2)O(3) solutions were heated to 400℃ under 1000 bar water pressure in a gold bag of Dickson gold-bag equipment (Fig. 1). At an elevated temperature Na(2)S(2)O(3) quickly and completely decomposed into 1:1 mixture of SO(4)(2-) and H(2)S (eq. (1)) and subsequent isotope exchange (eq. (2)) was monitored by consecutively withdrawing aliquots of solution for chemical and isotopic analyses at desired time intervals. For the preparation of SO(2) for isotope analyses, 2 to 5 mg BaSO(4) was thoroughly mixed with silica glass powder of 10 times the BaSO(4) in weight and heated to 1400℃ or so in sealed, evacuated silica glass tubings (see Fig. 2 and equation (4)). The technique is a modification of Holt and Engelkemeir (1971). The (18)O/(16)O ratios of SO(2) thus formed stayed constant by exchange with silica glass powder (Fig. 3). Numerical data of the three runs performed in this study are summarized in Tables 1 to 3. In runs 2 and 3, a small aliquot of (34)S- enriched H(2)SO(4) was added into the starting solution and thus equilibrium was approached from above the quilibrium value (see Fig. 4). When isotope exchange occurs between two molecules, X and Y, the reaction rate, r, is related to the extent of exchange, F, at given time, t, by equation (17), where X and Y indicate concentrations of given species, α(e), α(o) and α denote the fractionation factor at equilibrium, at time t=0 and at an arbitrary time t, and F = (α - α(o))/(α(e) - α(0)) or the extent of isotope exchange. Assuming the exchange rate is of the first order with respect to both X and Y and to the β'th power of hydrogen ion activity, a(H)(+), eq. (17) reduces to eq. (19), where k(1) denotes the rate constant. If X, Y and pH of solution stayed constant during the run, the half-time, t(1/2), of the exchange reaction can be obtained graphically as shown in Fig. 5. The t(1/2) for runs 1, 2, and 3 are determined to be 5.8, 5.5 and 6.1 hrs, respectively. Introducing F=0.5 and t=t(1/2) into eq. (19), we obtain eq. (20) which is graphically shown in Fig. 6 using the data by the present work and those by Sakai and Dickson(1978). The numerical values of log k(1) + 0.16 may be obtained by extrapolating the lines to pH=0 and, from these values, the rate constant, k(1) , may be calculated for temperatures of 300° and 400℃. From these two values of k(1) and from the Arrhenius plot, the activation energy of the exchange reaction was calculated to be 22 kcal/mole, a much smaller value than 55 kcal/mole obtained by Igumnov (1977). The value of β is found to be 0.29 at 300℃ and 0.075 at 400℃, although the physico-chemical nature of β is not clear to the present authors. Using these values, eq. (24), where C is a constant, is derived which would enable us to calculate the t(1/2) of any system of known ΣS and pH. However, as we do not know yet how β varies with different systems, eq. (24) is applicable only to limited systems in which temperature, total sulfur contents and pH are similar to those of the present study. Fig. 7 illustrates how t(1/2) varies with pH and total sulfur content at 300° and 400℃ and predicts t(1/2) for some solutions obtainable by hydrothermal reactions of seawater with various igneous rocks. The average equilibrium fractionation factor at 400℃ obtained by this study is 1.0153, in good accord with 1.0151 given by Igumnov et al. (1977). Theoretical fractionation factors between SO(4)(2-) and H(2)S have been calculated by Sakai (1968) , who gives too high values compared to the experimental data obtained by this and other researchers (Fig. 9). In the present study, the reduced partition function ratio (R.P.F.R.) of SO(4)(2-) was recalculated using two sets of the vibrational frequencies of SO(4)(2-) (shown in Table 5) and the valence force fields of Heath and Linnett (1947), which reproduces the observed frequencies of SO(4)(2-) better than Urey-Bradley force field used by Sakai (1968). The results of new calculation are shown in Table 6. This table also includes the R.P.F.R. of H(2)S which was calculated by Thode et al. (1971). Using these new R.P.F.R. of SO(4)(2-) and H(2)S, the fractionation factors between SO(4)(2-) and H(2)S were calculated and are listed in the last column of Table 6 and plotted in Fig. 9. Fig. 9 indicates that the new calculation gives values more shifted from the experimental values than before. The major sulfate ions in our solution at 300° and 400℃ exist as NaSO(4)(-) (Sakai and Dickson, 1978; see also Table 4 of this paper) and, therefore, the measured fractionation factors are those between NaSO(4)(-) and H(2)S. The discrepancy between the theory and experiments may, at least, be partially explained by this fact, although other more important reasons, which are not known to us at the moment, may also exist. |

| 抄録 | An automatic blood analyser, Coulter Counter Model Sr(CC-SR) was recently introduced in our hospital. This blood analyser is able to provide simultaneous measurements of seven blood parameters, i.e. WBC, REC, Hgb, Hct, MCV, MCH, MCHC, and also produces the results within 40 seconds from aspiration of the sample into the instrument. The performance and precision of this blood analyser have been clitically evaluated by comparing the results obtained from the previous blood cell counter, the Coulter Counter Model Dn (CC-DN), a haemoglobinometer, and a high speed centfugal separator. The results are as follows: 1) The precision and liniarity for readings and dilutions on WBC, RBC, Hgb and Hct by the use of the CC-SR is satisfactory. 2) Good correlation between the measurements by whole blood analysis procedure and micro sample analysis procedure is recognized. 3) The amount of carryover from one sample to the next is negligible for practical purpose. 4) High correlation factors are obtained between the measurements by the CC-SR method and former methods: i. e. 0.99 for WBC, 0.93 for RBC, 0.99 for Hgb and 0.99 for Hct. 5) For these reason, it can be said that CC-SR is more useful successive instrument to measure WBC, RBC, Hgb, Hct than the CC-DN and other above mentioned instruments. |

| 抄録 | In order to study the effect of bathing for 10 minutes, 34℃ and 40℃ in temperature, in the hot spring in Misasa on plasma metabolites of rats which took a bath once daily for one, two and four weeks, the body weight and the catecholamine, free fatty acid(FFA) and glucose contents in plasma were measured after serial bathing. The body weight tended to decrease by serial bathing compared with non-treated rats. Plasma noradrenaline (NA) content decreased slightly after one and four weeks-serial bathing, but no change was observed after two weeks-serial bathing. Adrenaline content showed the same tendency to decrease as NA content after one and four weeks-serial bathing, but it increased slightly after two weeks-serial bathing. Plasma FFA contents increased by serial bathing compared with those in controls. As to plasma glucose content, a slight decreasing tendency was observed after four weeks-serial bathing although no change was observed after one and two weeksserial bathing. |
