| 抄録 | The scanning electron microscopic studies of the clay minerals have usually been made on air-dried samples. The air-drying method is, however, not always preferable for H(2)O rich clay minerals such as imogolite because of their strong contraction in the dehydration process. The present writers examined the critical point drying for H(2)O rich clay mineral (imogolite) and proved that this drying method is excellent in preservation of natural surface of the minerals than that of air-drying. Imogolite which examined was separated from Kurayoshi pumice beds. The samples were treated first with OsO(4) solution and then were dehydrated progressively with ethanol. After completing above treatments, the imogolites which sealed in vessel were dried successively at critical point of CO(2). The samples were mounted onto brass stubs and coated first with carbon and then with Au-Pd alloy. The Japan Electron Optics Laboratory Co. scanning electron microscope Model JSM-50A which was installed in the Division of Rehabilitation Medicine in the present Institute was used at the operating conditions: accelerating voltage 25kV, magnifications ranging from 3000 to 40000. The scanning electron micrographs of the air-dried imogolite are shown in plate I, and cry tical point dried ones are in plate II and III. The former shows twig-like shape which indicated the effect of contractility, whereas the latter exhibits softly curled and entangled threads. The diameter of these threads ranges from 280A to 560A. |

| タイトル（別表記） | Hydrogen and oxygen isotopic ratios of thermal and mineral springs in Arima area |

| 抄録 | Saline waters of thermal and mineral springs in Arima area, at Takarazuka, and in Ishibotoke area of Kawachinagano City indicate wide ranges of δD and δ(18)O values (Table 1). Excellent linearity exists between the δD and δ(18)O values (Fig. 1) and between the δ(18)O value and the chloride concentration (Fig. 2). These facts as well as the chemical evidence of the previous investigators strongly support the view that Arima springs are admixtures of a single deep brine and local ground water (TSURUMAKI, 1964). The deep brine may have the δ(18)O value of +8.0～+8.5‰, the δD value of -25～-30‰, and the chloride concentration of 1.20～1.25 eq/l, which were estimated from the water of the maximum salinity so far reported. Because the thermal and mineral springs in Arima area closely associate with the upper Cretaceous granitic rocks, and the estimated δ(18)O value of the deep brine is similar to a value of water in isotopic equilibrium with those granitic rocks at 500～600℃, the deep brine of Arima might have been the magmatic water of those granitic rocks. The mineral springs at Takarazuka and in Ishibotoke area also show the similar linearity among Cl(-), δ(18)O and δD to those in Arima area. Therefore it is assumed that the mineral springs at Takarazuka may be of the same origin as that in Arima area, and the mineral springs in Ishibotoke area might have been the fluid associated with Ryoke metamorphic rocks. Alternatively, the deep brine in Arima area may be isotopically and chemically similar to the saline formation waters in Illinois basin (GRAF et al., 1966). The high δD values and salinities of those formation waters were attributed to the isotopic and chemical fractionation during the passage of water through sediments. The deep brine in Arima area may be genetically similar to those saline formation waters. If such a saline water could have formed in Osaka basin, it is not surprising to find out the similar brines at Arima and Ishibotoke which are the northwestern and southeastern rims of the basin, respectively. At the present, it cannot be answered which of these two models is more probable. Further studies on other saline springs fluid inclusions of Cretaceous granitic rocks may be useful in order to solve this problem. |

| タイトル（別表記） | Determination of manganese in serum by atomic absorption spectrophotometry |
| フルテキストURL | pitser_046_037_043.pdf |
| 著者 | 古野 勝志| |
| 抄録 | The manganese (Mn) concentrations in serum of 40 healthy controls (9 males and 31 females), and of 26 patients with rheumatoid arthritis (4males and 22 females) were determined using a HITACHI MODEL 207 atomic absorption spectrophotometer. Wavelength of Mn determination was setted at 2795 A. Flow rate of acetylene was setted at 3.0 l/min and lamp current was setted at 10 rnA. The serum samples were ashed by IPC MODEL 1003plasma machine, and dissolved in 3N-HCl and evapolate on the hot plate, and redissolved in constant volume of 0.1 N-HCl. These sample solution were aspirated directly into the burner. Mn levels in serum were estimated by standard curve. The mean recoverry rate of ashedsample solution was 100.1%, and that of serum by ashing process was 101.6%. The serum Mn levels in 40 healthy controls and 26 patients with rheumatoid arthritis were 2.19 ± 0.34 (S.D.), 3.04 ± 1.01 (S.D.) μg/100ml respectively. The serum Mn levels in rheumatoid arthritis were significantly higher than healthy control levels (p<0.001). In 10 of 26 cases (38%) with rheumatoid arthritis, the serum Mn levels were shown to be above the upper limit of 5% rejection limit of healthy controls. |

| 抄録 | Copper (Cu) and Zinc (Zn) in serum of 113 healthy controls (43 males and 70 females) and of 68 patients with rheumatoid arthritis (19 males and 49 females) were determined using a HITACHI MODEL 207 atomic absorption spectrophotometer. Wavelength and lamps current of Cu and Zn were setted at 3247 A, 2139 A, and 10mA, 9mA respectively. Flow rate of acetylene and air were setted at 3.0 l/min, and 13.0 l/min. The stock standard solutions of Cu and Zn were 0.5 mg, 1.0mg, 2.0mg and 3.0mg per 100mE in 0.01 N·HCl. For working standard solutions, these stock standard solutions were diluted to 50μg/100ml. 100μg/100ml, 200μg/100ml and 300μg/100ml with 20% glycerine. Serum and working standard so· lutions 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 recorder. Various acids and other elements had few influences on the determi· nations of Cu and Zn. The mean recovery rate of Cu and Zn in serum were 100.5% and 100.8% respectively. By this method, the levels of Cu and Zn in healthy controls were 103.0±14.5 (S.D.), 116.2±18.6 (S.D.) μg/100ml in males and 108.7±19.6 (S. D.), 110.3±14.7 (S.D.) μg/100ml in females respectively. No sex difference were observed. The ratio of Cu and Zn (Cu/Zn ratio) of healthy controls were 0.89±0.17 (S. D.) in males and O.99±0.25 in (S.D.) females. The sex differrences of Cu/Zn ratio were statistically significant (p<0.05). The levels of Cu and Zn in rheumatoid arthritis were 141.7±25.2 (S.D.). 89.1±14.5 (S.D.) /-Lg/100 mP and 154.l±29.7 (S.D.), 86.7±18.1 (S.D.) μg/100ml in females respectively. No sex differren· ces were observed. The Cu/Zn ratio were 1.64±0.43 (S.D.) in males and 1.82±0.48 (S.D.) in females, wich showed no sex differrences. In patients with rheumatoid arthritis, serum Cu levels were significantly higher (P<0.001) and serum Zn levels were significantly lower (P<0.001) than in healthy controls in both sexes. The Cu/Zn ratio were significantly higher (P<0.001) rheumatoid arthritis than in controls. The serum Cu in 13 of 19 males (68%), and 30 of 49 females (61 %), with rheumatoid arthritis were shown to be above the upper limit of 5% rejection limit in healthy controls. The serum Zn in 3 of 19 males (16%), and in 24 of 49 (47%) with rheumatoid arthritis were shown to be below the lower limit 5% rejection limit in healthy controIs. The Cu/Zn ratio in rheumatoid arthritis, in 14 of 19 males (74%), and in 35 of 49 females (71%) were shown to be above the upper limit of 5% rejection limit in healthy of males and females. So, differences in Cu/Zn ratio between healthy controls and rheumatoid arthritis were proved to be more pronounced. |

| 著者 | 古野 勝志| |
| 抄録 | 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. |

| タイトル（別表記） | Evaluation of the coulter counter Model Sr |

| 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. |

| タイトル（別表記） | Isotopic Analysis of Rb and Sr Using a Full Automatic Thermal Ionization Mass Spectrometer |

| 抄録 | Analytical method for strontium isotope ratios and rubidium and strontium concentrations has been established using a full automatic thermal ionization mass spectrometer. The machine is a modified model "MAT 260" of Varian MAT LTD. Each of simultaneously loaded thirteen samples is successively analysed full automatically following to a specific controling program which has been selected as being most suitable for each sample. However, the most characteristic feature of this machine compared to other types is computer controled peak jumping and peak centering before measurment of the signal of each peak. By this the accuracy of isotopic measurement has been surprisingly improved. Analytical procedures are described in detail which include decomposition of samples, separation of Rb and Sr, loading samples on filament and mass spectrometry. Accuracy and reproducibility of isotope analyses are excellent : 43 separate analyses of standard sample NBS 987 over one year gave a mean (87)Sr/(86)Sr ratio of 0.710238 (normalized to the (88)Sr/(86)Sr ratio of 8.375209) with a value of 20δ of 0.000008. The ratio obtained is slightly higher than the value of 0.71014 given by NBS, but it is almost identical to the mean of recently reported twenty analyses. Our determinations for Rb and Sr concentrations of standard samples are as follows : JG-1, Rb 184.4 ppm, Sr 185.5 ppm; JB-l, Rb 41.5Ppm, Sr 448.4 ppm , each of which is near the mean of reported values for corresponding element of the sample (ANDO et al., 1974). Concentrations of Rb and Sr in pure water and regents used in chemical treatement of samples were also measured; a possible error due to the contamination is negligible for most geochemical samples. |
