| 抄録 | 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. |

| 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 |

| 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). |

| 著者 | 古野 勝志| |
| 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） | The determination of uric acid using modified Patel's method |
| フルテキストURL | pitsr_050_025_031.pdf |
| 著者 | 西村 佳子| 青木 宏子| 御舩 政明| |
| 抄録 | N 13-b method for determination of uric acid by AutoAnalyzer- I was proposed from Technicon Corporation, but the sensitivity of this method was insufficient. According to the modification by Patel, good sensitivity was obtained for determining of uric acid, but insufficient separation between peaks was accompanied. To get good separation, Patel's method was reexamined by the authors, and the results were as follows. Sufficient separation was obtained by modifing the flow diagram of Patel's method. The mean recovery rates of uric acid added to serum and urine were 103.6% and 102.5%, and coefficients of variation were 1.27% and 1.05% respectively. The correlation between this modified Patel's method and the U.A. test Wako method was recognized (serum : n=95, r=0.97, urine : n=35, r =0.99). According to our modified method, uric acid concentration in serum of 68 subjects, were 5.8±0.9mg/100ml in 29 males and 4.4±0.8mg/100ml in 39 females. |

| タイトル（別表記） | An isotope study of hot springs in Nagano Prefecture |
| フルテキストURL | pitsr_050_017_024.pdf |
| 著者 | 松葉谷 治| 酒井 均| 日下部 実| 佐々木 昭| |
| 抄録 | Water samples from 28 hotsprings and mineral springs in Nagano Prefecture, central Japan, were examined for their stable isotope ratios of hydrogen, oxygen, carbon, and sulfur. Spring waters of Kashio are highly saline and enriched in heavy isotopes of oxygen and hydrogen (δ(18)O=-2.5～-4.6‰, δD=-54～-57‰). Linear relationships among δD, δ(18)O, and Cl(-) suggest that spring waters are the mixtures of a deep brine and local surface water. Extrapolation of the linear relationships indicates that the deep brine is both isotopically and chemically very similar to the deep brine previously suggested for the springs of Arima, Takarazuka, and Ishibotoke of which δD, δ(18)O, and Cl(-) are estimated as -33‰, +8.0‰, and 44g/l, respectively. A common origin may be warranted among these postulated brines, while their provenance is yet to be worked out. The hot springs in Matsushiro are a Na-Ca-Cl type of high carbonate content. Their hydrogen and oxygen isotope ratios (δD=-71～-46‰, δ(18)O=-9.1～-2.0‰) are higher than the local surface water. On the basis of the relationships among δD, δ(18)O, and Cl(-), they are considered to be the mixtures of fossil sea water and certain water of meteoric origin of which Cl(-) is about 4g/l and δ(18)O is higher by about 3‰ than the local surface water. The latter may be meteoric water circulating in the marine sedimentary formations (Green Tuff formations) with soluble sea salts. Isotopic exchange with carbonate minerals in the formations explains its (18)O enrichment. Spring waters from Yashio and Isobe (Gunma Pref.) as well as Yunosawa and Yatate (Akita Pref.) were previously interpreted to be mixtures of fossil sea water and local surface water of low Cl(-) content. Re-examination of their data revealed that the meteoric waters responsible for these springs contain about 3g/l Cl(-), similar to the value obtained for Matsushiro. However, unlike Matsushiro, the meteoric waters in these areas are found to be isotopically similar to the local surface waters. Waters from other hot springs studied here are of simply meteoric origin, thus belonging to the GreenTuff type water previously defined. |

| 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 |
| フルテキストURL | pitsr_050_001_015.pdf |

| 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. |

| タイトル（別表記） | Evaluation of the coulter counter Model Sr |
| フルテキストURL | pitsr_051_057_063.pdf |
| 著者 | 西村 佳子| 山根 幸子| 馬野 富美江| 御舩 政明| |
| 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. |

| フルテキストURL | pitsr_051_053_056.pdf |
| 著者 | 妹尾 敏伸| |
| 抄録 | In attempt to clarify the effect of serial bathing on metabolic actions of noradrenaline (NA) by using rats which took a bath (for 10 minutes, 40℃ in temperature) in the hot spring in Misasa or a city water once daily for one and four weeks, changes in plasma metabolites after the injection of NA (20μg/100g, subcutaneously) were studied. No significant difference in the rising degree of plasma free fatty acid (FFA) or glucose levels by NA injection was observed in rats which took serial bathing for one week, while triglyceride levels of rats, which took a city water bath, rised significantly by NA in jection. After serial bathing for four weeks, however, remarkable difference in the rising degree of FFA levels by NA injection was observed between rats taking a city water bath and ones taking hot spring bath and between rats taking a bath and non-treated ones. The rising degree of glucose levels by NA injection was slightly supressed only in rats taking a city water bath compared with nontreated rats. Little difference in the rising degree of β-hydroxybutyrate levels by NA injection was observed in rats taking serial bathing for one or four weeks compared with non-treated rats. |

| 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. |

| 著者 | 古野 勝志| |
| 抄録 | Dose rates of environmental radiation were determined with NaI (Tl) cristal scintillation survey meter at Misasa, Sekigane and Ikeda spa areas which were known as radioactive spring in the Sanin districts. The results were as follows ; (1) Dose rates of radiation in the air of outdoor at spa areas of Misasa, Sekigane and Ikeda were 11.8±2.3μR/h, 11.3±2.1μR/h and 18.4±5.8μR/h, respectively. Dose rates of radiation in the air of these spa areas were significantly higher (P<0.01) than at none spa area of Kurayoshi city (8.6±1.2μR/h). Dose rates of radiation in the outdoor air at Misasa and Sekigane tends to increase near the spring sources. (2) In the room where spring water is not used, dose rates of radiation in the air were 9.5～10.5μR/h. Dose rates of radiation in the air of the room with facilities using spring water were determined; peloid therapy room: 13.3±0.5μR/h, Hubbard bath room : 12.5±0.4μR/h, drinking hall : 11.8±0.7μR/h, hot air bathing room : 18.2±1.7μR/h, usual bath room (Onkensen) : 13.0±1.0μR/h and bath room for patients : 17.9±1.2μR/h (males), 17.0±1.2μR/h (females), respectively. Dose rates of radiation in the air of the bath room of Gunze-hotel and Ohashi-hotel-Gankutsunoyu were 30.1±9.0μR/h and22.3±3.0μR/h, respectively. At Ikeda spa, dose rates of radiation in the air of the guest room and the bath room were range of 13.0～19.0μR/h and 14.0～23.0μR/h. |
