| 抄録 | The author studied the influence of a series of radioactive hot-spring baths, lasting 20 or 30 days, upon leukocyte functions in healthy male rabbits and in patients with rhenmatoid arthritis and other diseases. The radioactive hot springs used were "Hisui-no-Yu" and "Kenkyusho-sen" (the laboratory spring), both in Misasa Spa, the chemical compositions of which are deseribed in Table 1. The following results were obtained: 1) Wandering velocity of pseudo-neutrophilic leukocytes: When a series of plain water baths (41℃., for 5 minutes daily), were administered, velocity increased after the first bathing but later remained fairly constant, compared with initial levels, except for a temporary fall on the 9th day (Fig. 3). During the administration of a series of the weakly radioactive "Kenkyushosen" baths (43℃., for 5 minutes daily), it showed a slight increase during the first week, following a temporary fall after the first bathing, and a decrease during the third week, but it tended to return to the initial level by the forth week (Fig. 1). In the course of a series of the radioactive ·Hisui-no-Yu" baths (40℃., for 10 minutes daily), it increased during the first week and tended to decrease during the second week, but returned to the initial level by the third week (Fig. 2). 2) Phagocytic ability for carbon-particles of pseudo-neutrophic leukocytes in rabbits: When plain water baths were given, phagocytic ability showed a rise on the third day, after which it declined to the initial level and remained fairly constant to the end of the observation period (Fig. 6.). On the other hand, the phagocytic ability of the leukocytes in rabbits of the groups receiving radioactive hot-spring baths increased more and more markedly as serial bathing was continued, although it had slightly decreased immediately after the first bathing. The rise of phagocytic ability in the group bathed in "Kenkyusho-sen" was especially marked on the third and ninth days of serial bathing, and also on the tenth day after serial bathing had been discontinued (Fig. 4). This tendency was also observed in the group bathed in "Hisui-no-Yu", whose phagocytic ability was noticeable especially on the third and 14th days. The degree of the rise in phagocytic ability was demonstrably high in this group than in the former (Fig. 5). Acceleration of the phagocytic function of leukocytes in rabbits was observed up to the 40th day after the series of baths in the radioactive hot spring had been concluded. 3) From these findings. it is obvious that leukocyte function is increased by repeated bathing, but it should be kept in mind that a so-called dissociation phenomenon is present between the wandering velocity and the carbon-phagocytic ability of leukocytes in the groups bathed in hot springs: namely, wandering velocity showed a tendency to decline during the third week, while carbon particle phagocytic ability showed a marked increase during the same week. 4) In order to explore the effects of a series of radioactive hot-spring baths on leukocyte functions in patients with rheumatoid arthritis or other similar diseases (for example, back pain, fibrositis or neuritis), the author examined the wandering velocity and the phagocytic ability of neutrophils, and obtained the following results: The wandering velocity of neutrophils in patients with rheumatoid arthritis or similar diseases generally showed a tendency to increase during the adminlstration of a series of the radioactive "Kenkyusho-sen" baths at a temperature of 42～43℃. (Fig. 7). The carbon-particle phagocytic ability of neutrophils gradually increase from about the seventh day onward and reached a maximum during the second week, in patients with back pain, fibrositis and neuritis (Fig. 8a). In patients with rheumatoid arthritis, however, it declined temporarily on the fifth to seventh days in 3 out of 5 patients but thereafter increased gradually, reaching its maximum on the 20th day (Fig. 8b). Thus, the leukocyte functions in patients with rheumatoid arthritis are accelerated by serial bathing, but the response in some patients may be a decline of carbon-particle phagocytic ability during the first week. This is probably due to the stress bathing imposes on adrenocortical functions. It is believed, on the basis of the facts described above, that follow-up examinations of leucocyte functions can afford a better understanding of the effects of radioactive hot springs on the defence mechanisms operative in living bodies. |

| 抄録 | Sixty-five samples of mineral waters (mainly above 25℃) from western Japan were analyzed for their Li, Na, K, Mg, Ca, Al, Fe, and Cl contents. The determination of Li was carried out by argentimetric titration of LiCI after the removal of other components by the cation exchange chromatography. A significant correlation between Li and Na concentrations is demonstrated in most samples, in which the contamination of sea water is hardly conceivable. This strong correlation of Li and Na can plausibly be explained assuming that these components have dissolved into the ascending mineral waters from the country rocks having fairly uniform Li to Na ratios. In this connection it is noted that western Japan is characteristic of the vast outcrops of granodioritic or granitic rocks. |

| 抄録 | Misasa Hot Springs water contains 4.81-1169.2×10(-10) curie per liter of radon and its temperature ranges from 53.0℃ to 76.0℃. The authors examined one group of 265 residents who are living over 1 year at Misasa Hot Springs and another control group of 226 residents at the middle district of Tottori Prefecture, where the Misasa area is singular for its high radon concentration. A living environment of these two groups is of same condition, for example, dietarily or economically. The incidences of abnormal ECG findings and hypertension in the both groups was analysed stochastically and the results obtained were as follows: 1. The incidences of abnormal ECG findings were found less in the residents at the radioactive hot springs area than another residents at the middle district of Tottori Prefecture. 2. The difference in these incidences were found especially about the ECG findings due to functional disorderes, for example, sinus tachycardia and bradycardia, premature supraventricural and ventricural systole, atrio-ventricural block and right bundle branch block. 3. The ECG findings due to organic disorderes, for example, both auricural and ventricural hypertrophy or strain, myocardial and coronary arterial lesions, auricural fibrillation and left bundle branch block, were not found different significantly between both groups. 4. No difference of the incidences of the functional and organic abnormal ECG findings between both aging groups, over 60 years old, were found. 5. The incidences of hypertension were not found different between both groups. |

| 著者 | 梅本 春次| |
| 抄録 | The ratio (234)U/(238)U of two groups of ores and the waters collected in Kannokura Deposit was determined by α-ray spectrometry. According to the geological and mineralogical observation, the ores of each group were formed in succession. Based on the assumption that (234)U/(238)U of the uranium in the leaching solution is higher than that in the ores, the obtained ratio supports the above mechanism of formation. Actually, the waters collected in Kannokura Deposit showed the fairly high value in (234)U/(238)U. Each stratum of a typical section of the mine was observed on the ratio, but the obtained values were in too much complicated relation to interpret. |

| 抄録 | Human venous blood pH, P(CO(2)) and P(O(2)) were measured with I. L. Meter. Its reproducibility and response rate were evaluated as well as methods of the procedures. 1) Time required to reach the stability of pH, P(CO(2)), and P(O(2)) reading after the sampie injection was 1～1.5 min., 2～2.5 min. and 45～75 sec., respectively. It is recommended in the measurement of these parameters at the same time that the sample injection starts with P(CO(2)) electrode, followed by pH and P(O(2)) in this order and that readings are recorded in the order of pH, P(O(2)) and P(CO(2)). 2) Range of differences between the two values measured in the interval of 3～5 min. were pH : -0.010～0.020 (mean: 0.003), P(CO(2)) : -1.0～1.0mmHg (mean: 0.4) and P(O(2)) : -1.0～0.0mmHg (mean: -0.5). Their 5% rejection limits were 0.021≧x(o)≧-0.015, 2.0≧x(o)≧-1.2mmHg and 0.3≧x(o)≧-1.3mmHg, respectively. 3) The pH, P(CO(2)) and P(O(2)) of the heparinized venous blood stored in ice water showed no significant changes in 60 min. and they gave practically the same results as the measurement just after shedding. |

| タイトル（別表記） | Follow-up results of rheumatic disorders treated with hot springs |
| フルテキストURL | pitsr_039_077_080.pdf |
| 著者 | 松本 欣之| |
| 抄録 | Misasa Spa, located in Tottori Prefecture, was discovered in 1164, and it has been widely used for the management of rheumatic disorders, gastrointestinal diseases and so on. In 1914, Dr. R. ISHIZU measured radon contents in Misasa spring waters to be 142.14 Mache, and then Misasa Hot Springs, alkaline common salt springs, were also known as radioactive hot springs. In July, 1958, patients with rheumatic complaints who had balneotherapy at Misasa Branch Hospital of Okayama University, from January, 1955 to March, 1958, were reexamined. A questionnaire about the effectiveness of balneotherapy was sent to 149 patients and 98 answers were received. The results were as follows: 1. Spa treatment was effective in 100% of shoulder-hand syndrome and osteo-arthrosis of the knee, in 95% of degenerative spondylosis, in 93% of rheumatoid arthritis, in 80% of low back pain, in 67% of sciatica, etc. Generally speaking, balneotherapy was effectual in 78 of 98 patients with rheumatic disorders (81.2%). 2. The effectiveness of spa treatment came out in the course of thermal cure in 74% of 78 cases, and the others recognized the effects after spa treatment was finished. 3. The effect of spa therapy on the subjective complaints was notable in the cases which had a period of spa treatment over half a month. In the cases which had a period of spa treatment within 2 weeks, it is thought that the period is too short to reveal the efficacy of hot spring bathing. 4. It appeared that drinking of hot spring water had no remarkable effect on rheumatic complaints. 5. Forty-three per cent of the cases answered that their body conditions during this inquiry time became better than that at the beginning of the balneotherapy, and the remainders of the reexamined cases were under the trcatments with cortisone, vitamine, massage, acupuncture and so forth. |

| タイトル（別表記） | The effect of radioaclive thermal bathing upon serum iron values |
| フルテキストURL | 039_061_075.pdf |
| 著者 | 山本 泰久| |
| 抄録 | The author investigated the effect of radioactive hot spring bathing on serum iron values. The serum iron values were measured by Umemoto-Yamamoto's method using o-nitrosoresorcin monomethylether, as a colour-developing reagent. The chemical compositions of the spring water used is as following: pH : 7.04, Rn : 38-151x10(-10)curies/l, K(+) : 14.0, Na(+) : 540.2, Ca(++) : 61. 2, Mg(++) : 6.6, Fe(++) : 89.0, AI(+++) : 0.1, Cl(-) : 709.5, S0(4)(--) : 179.5, HCO(3)(-) : 226.7, H(2)SiO(3) : 89.0, HBO(2) : +, CO(2) : 29.5, totaling 1,827mg/kg. 1) Single bathing: The iron values in the serum were measured before and after 0, 1/2, 1 and 2 hours after the radioactive thermal bathing for 10 minutes in water of 41 ±2℃ in temperature. Single thermal bathing showed no significant effect on the serum iron values in healthy hnman subjects, but the serum iron concent:'ations in healthy white rabbits tended to decrease following single thermal bathing and to remain at a decreased level for 1/2 to 1 hour, and returned to normally within 2 hours from the time of the bathing (Table 1, 2 and Fig. 1, 2). 2) A series of baths: The author examined the serum iron values of patients with rheumatic disorders before and 3rd, 7th, 14th, 21st and 28th days after in the course of "a series of baths" in radioactive hot spring. Patients bathed in water of 41 ± 2℃ in temperature, for 5-10 minutes, 2 or 3 times daily. A fall in the serum iron values was seen on the 3rd to 7th days. At that time the pattern of iron absorption from intestine showed a iron dificiency anemia type. The rate of absorption of iron was rapid. At about the 14th day, the serum iron values of patients tended to increase but unbound iron-binding capacity of the serum decreased. Subsequently, the serum iron values returned to the initial levels between the 21st and 28th day (Table 3, 4, 5, and Fig. 3, 4, 5), 3) It is said that the reticulo-endothelial system plays an inportant part in iron metabolism. The author injected 5 ml of Indian ink into the aural vein of rabbits for the purpose of blocking the reticulo-endothelial system. These procedures were carried out once a day for 7 successive days. The rabbits with "a blockade of R. E. S." had no significant change in the serum iron values during a series of baths. From what has been stated in the above, it may be said that bathing in radioactive hot springs regubtes the iron metabolism of patients with anemia and brings about the acceleration of the medullary function. |

| タイトル（別表記） | Isotopic study of Hot Springs in Japan, I Techniques for oxygen isotopic analysis of spring water |
| フルテキストURL | pitsr_040_033_040.pdf |
| 著者 | 松葉谷 治| 酒井 均| 田中 ひな子| 上村 多鶴恵| |
| 抄録 | The CO(2)-H(2)O isotopic equilibration technique was studied for the routine analyses of the oxygen isotopic ratios of hot spring water. A reaction vessel containing 2 ml of water and 0.16 m mole of tank CO(2) was shaken for 18 hrs. in a constant-temperature bath at 25.0℃ (Figs. 1, 2, and 3), and the CO(2) was analyzed for the oxygen isotopic ratio by a MCKINNEY type mass spectrometer. Several aliquots of 1, 2 and 5 ml from a same water were each analyzed three times by successive equilibration (Table 1). The observed values differ depending on the volume of water but the corrected values by equation (6) indicate excellent agreement, implying the whole processes to be well controlled. The reproducibility of the isotopic analyses is better than ± 0.1‰ (Table 2) in most cases, and the accuracy would not be worse than ± 0.2‰ as demonstrated by the interlaboratory comparison of some standard samples (Table 3). Oxygen isotopic ratios of water from more than 70 hot springs in Japan are presented (Table 5). Although the results will be discussed in the following issues of this series of paper, most hot spring water have the δ(18)O values similar to those of meteoric waters in Japan. However, spring water from Arima Hot Springs, Hyogo-Pref., which has been known by its abnormally high chloride and low sulfate concentrations is of an exceptionally high δ(18)O value. |

| タイトル（別表記） | Clinical studies on electromyographic changes in rheumatoid arthritis Part III. Effect of radioactive hot spring baths |
| フルテキストURL | pitsr_040_001_017.pdf |
| 著者 | 池上 忠興| |
| 抄録 | The author observed the changes in electromyographic patterns of 14 patients with rheumatoid arthritis (13 cases of classical rheumatoid arthritis and one case of definite rheumatoid arthritis) bathed 2 or 3 times daily in hot spring water at Misasa Spa, at a temperature of 40±1℃, 5-10 minutes. The electromyographic examination was performed on the biceps brachii, opponens pollicis and the abductor pollicis brevis. Intramuscular temperature was measured in the deltoid muscle. The results were as follows. 1) The intramuscular temperature in cases of rheumatoid arthritis did not deviate from normal subjects. 2) After the general spring bathing the intramuscular temperature increased about 1℃ and it had no difference between the patients with rheumatoid arthritis and normal subjects. 3) With increasing intramuscular temperature by the general spring bathing in cases of active rheumatoid arthritis the mean potential amplitude decreased and the mean potential duration increased. 4) With increasing intramuscular temperature by the general spring bathing in cases of inactive rheumatiod arthritis the mean amplitude increased and the mean duration decreased. 5) The patterns of potential duration and amplitude before and after a bath on re-examination, one month after a series of the general spring baths, showed a tendency of reverse of the initial patterns. 6) After two months of a series of the general spring baths, the patterns of electromyographic changes of patients with rheumatoid arthritis following the bathing were similar to the initial patterns. |

| タイトル（別表記） | Studies on chrysotherapy in rheumatoid arthritis, III. Gold determination by the atomic absorption spectrophotometry |
| フルテキストURL | 041_035_048.pdf |
| 著者 | 高橋 和枝| |
| 抄録 | The gold concentration in serum, synovial fluid and urine has been determined using a HITACHI MODEL 207 atomic absorption spectrophotometer. Flow rate of acetylene was setted at 2.0l/min. and lamp current was setted at 8mA. The samples were pretreated by the determination of gold. Serum was diluted with deionized water by two to ten-fold. To O.2ml. of synoival fluid 50units/ml of hyaluronidase was added and then incubated for 20 minutes at 37℃. This sample was then treated the procedure for serum given previously. Urine was treated using the modification method of Christions procedure. The recovery rates with gold sodium thiomalate in serum, synovial fluid and urine were 99.9%, 102.5% and 93.6% respectively. When gold sodium thiomalate was injected in rabbits, the maximum serum gold level was attained 1 hour after injection and then gradually decreased at about 50% of the maximum level 24 hours after injection. In the observations of changes in the gold levels in the serum of patients with rheumatoid arthritis after injection of gold sodium thiomalate and gold thioglucose, its peak level after gold thioglucose injection tended to be slightly lower as compared with the same amount of gold sodium thiomalate injection. In those patients who had been given 300 mg. or more of gold salt-preparation, one additional injection of 25 mg. of gold salt could attain the gold level of around 200μg/100ml, in serum a week later, and this level was very nearly the same with that after 3-4 days of one additional injection of 1Omg. of gold salt. The amount of gold excreted in the urine varied from patient to patient, and the mean excretion rates of gold sodium thiomalate and gold thioglucose in the urine within 24 hours after intramuscular administralion were 9.8% and 6.5% respectively. The simple, rapid and accurate method for analysis in biological specimens using atomic absorption spectrophotometer would offer one of the excellent measures in the clinical management of patients with rheumatoid arthritis. |

| タイトル（別表記） | On the measurement of oxygen and carbon isotopic ratios of carbonates |
| フルテキストURL | pitsr_041_009_012.pdf |
| 著者 | 渡辺 洵| 松葉谷 治| |
| 抄録 | Oxygen and carbon isotopic ratios of two working standards of our laboratory and three other standards were measured by McCrea's technique and the new McKINNEY type mass spectrometer in this Institute. The reproducibility of δ(13)C measurement is about ±0.2‰. Some systematic differences in δ(18)O values were observed among the three measurements in Apr.-May, July, and Aug., 1971. Because these systematic differences are supposed to be caused by the imperfection in the processes of decomposition of carbonates by phosphoric acid, the reproducibility of δ(18)O measurement may be ±O.2‰ in most cases. The calibrations of our working standard, CK-13, against the PDB standard were carried out on the assumption that δ(18)O and δ(13)C of CK-13 are -1.75‰ and +O.54‰ relative to PDB, respectively. The accuracy of these calibrations is about ±O.2‰ as shown by the interlaboratory comparison of some standards (Table 3). The δ(18)O values of the two working standards relative to PDB are independently recalculated relative to SMOW based on the two assumptions (Table 4). One of which is that a standard water MSA-2 is -8.20‰ relative to SMOW, and the other is that the δ(18)O of CK-13 is -1.75‰ relative to PDB. The results of both calculations agree within 0.4‰. |

| 抄録 | Since the installation in April 1970, the McKinney type mass spectrometer has maintained a good condition and about 5000 isotopic analyses of oxygen, carbon and sulfer has been cerried out so far. The ion source filament was changed to spiral one from single wire. Consequently three times sensitivity and the longer life of filament were obtained. Gradual changes in the ratio of potential divider (β) and the sensitivity (|△ E(0)(2)|/E(0)(1)) for the difference of β have been observed (Table 1). Because these changes are opposite in trend but similar in degree, it is supposed that these changes are caused by decrease of feed-back resister value in the balancing system. Although there remain some problems in the corrections for the difference in observed isotopic tatio between two cases that a same CO(2) is fed to ion source from the ST side of inlet system on the one hand and from the X side on the another, the reproducibility of the measurement of isotopic ratio for long period is about ±O.1‰ (Table 2, Fig. 1). δ(18)O values of standard waters, MSA-1 and MSA-2, measured during a period from May to Dec. 1970 and in Sep. 1971 yielded good agreements implying the reproducibility of the measurement to be constant (Table 3). Both calculated δ(18)O values relative to a given sample based on each observed δ(18)O value relative to two different samples agreed each other. It is concluded that the linearity of observed a-value holds over a range of 30‰ (Table 4). |

| タイトル（別表記） | The effect of pH of water on the measurement of oxygen isotopic ratio by means of CO(2)-H(2)O isotopic exchange technique |
| フルテキストURL | pitsr_041_001_002.pdf |
| 著者 | 松葉谷 治| |
| 抄録 | The effect of pH of water on the measurement of oxygen isotopic ratio by means of CO(2)-H(2)O isotopic exchange technique was studied. In this study, a new type of reaction vessel was used (Fig. 1). The reaction time for equilibration using this new reaction vessel was nearly equal to that in the previous study (Fig. 2). The oxygen isotopic ratios of each two samples of pH 2, 4, 7, 8, 9, and 10 were measured. There is no significant difference between the observed δ(18)O values of these samples (Table 1). Therefore it is concluded that the effect of pH of water needs not to be taken into account on the measurement of oxygen isotopic ratio by means of CO(2)-H(2)O isotopic exchange technique. |

| 抄録 | Oxygen isotope analysis was carried out, by use of a new method (oxalate equilibration method) of preparing CO(2) for mass spectrometry, on water samples extracted from a number of biological samples collected in Misasa Town and Hashizu Coast, Tottori Prefecture. The δ values (the per mil enrichment of (18)O in sample waters relative to the Standard Mean Ocean Water) were suggested to be distributed in the living things as follows. The water absorbed by plant roots was supposed to have the same δ value with the water outside it (δs. about -8‰), and in a rapidly transpiring plant, this water reached the leaves, partly infiltrating into the phloem. When transpiration was slow, on the other hand, the isotopic composition of ascending xylem sap was modified by the exchange of water with phloem. where leaf water with a higher δ value was migrating. As Gonfiantini et aI. (1965) and Dongmann et al. (1972) have odserved, leaf waters were enriched markedly in (18)O in the daytime. A criterion of the δ of leaf water may be the sum of δs and △δ that corresponds to the (18)O fractionation factor in the H(2)O(I)-H(2)O(v) system. The sum comes to about 0‰ at ordinary leaf temperatures. and really δ values near 0‰ were observed in leaves of some herbaceous plants, in exudate from a tip of vine of Kudzu, in body fluid of herbivorous insects, etc., but higher δs (up to +19‰) were also observed in some other leaves such as pine needles, Especially leaves showed an increase in δ by about 10 ‰ toward the pnd of November when the average temperature fell below 10℃, probably because of accumulation of the daily enrichment as a resul t of slow water absorption and circulation. A few plant species grown on a dune were analyzed and it seemed that, among them, herbaceous plants were dependent on spraied sea water and pine trees on ground water. δ's of petal water were dispersed (-9～-3‰), probably according to the volume-to-transpirational flux ratio of water in the petals. Succurent fruits in enlarging stage seemed to have lower δ's near δs, but in maturing stagp δ's increaspd to about -4‰, i.e., to the avpraged δ of Ieaf water in the day and night. Herbivorous insects (imagines and la rvae) in general had distinctly higher δ values than carnivorous insects, the border being at -1‰. However, lower δ's at about -5‰ were obserbed on aphides which might have been sucking somewhat dilutpd leaf water from seave tube cells. Sometimes the δ of a herbivorous insect was a few per mil higher than that of the leaf it was nibbling, probably as a result of evaporation of water from the insect and of respiration. The level at about -3‰ common for carnivorous insects could not be explained, although tipula and chironomus making a swarm also showed a δ value on the level. Blood of a heron did not show such a low δ as supposed from its food habit. As compared with the drinking water of -8‰, blood and urine were found to have an identical δ in the range of -4 to -5‰ in either mouse or man, The δ value of the oxidation water produced in man's body was estimated to be about -6‰ from an approximate water balance. |
