| Abstract | 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. |

| 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 | The determination of uric acid using modified Patel's method |
| FullText URL | pitsr_050_025_031.pdf |
| Author | Nishimura, Yoshiko| Aoki, Hiroko| Mifune, Masaaki| |
| Abstract | 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. |

| Title Alternative | Isotopic Analysis of Rb and Sr Using a Full Automatic Thermal Ionization Mass Spectrometer |
| FullText URL | pitsr_052_051_070.pdf |

| Abstract | 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. |

| Abstract | Histamine released from whole blood was determined by an automated fiuorometric histamine analysis system. The increased release of histamine from basophils by anti-IgE was observed in ten healthy subjects and 12 extrinsic asthma patients, while the release in 11 intrinsic asthma patients was significantly less as compared to that in healthy and extrinsic asthma subjects. House dust extract caused a significant increase in the histamine release from basophils of the extrinsic asthma patients who are sensitive to house dust. It was concluded from this study that histamine released from basophils could be easily determined by an automated analysis system and that the method is useful for the diagnosis and study of allergy. |

| Title Alternative | Determination of ferritin in serum and in synovial fluids of patients with rheumatoid arthritis |
| FullText URL | pitsr_053_001_008.pdf |
| Author | Furuno, Katsushi| Morinaga, Hiroshi| Irino, Shozo| |
| Abstract | Ferritin in sera and in synovial fluids were determined by method of immunoradiometric assay (IRMA) and of radioimmunoassay (RIA). These methods have been proved to be reproducible. The coefficient variation was 7.4 to 9.9% in IRMA and 5.6 to 8.0% in RIA. There were a good correlation between methods of IRMA and of RIA (r=0.989). The mean recovery rate of ferritin in serum was 101.2% in IRMA and 101.0% in RIA, respectively. The determination of serum ferritin revealed a 16% reduction in average after preservation at -20℃ during over 100 days. The levels of serum ferritin in healthy controls were 131.4±52.1 ng/ml in 34 males and 58.4±39.9 ng/ml in 38 females. The sex differences were statisticalIy significant (p<0.01). Ferritin levels were shown to be below 30 ng/ml (the state of iron deficiency) in 2 of 34 (5.9%) males and in 8 of 38 (21%) females of healthy controls. The levels of serum ferritin in patients with rheumatoid arthritis (RA) were 337.0±293.4ng/ml in 10 males and 181.4±329.9ng/ml in 25 females. The serum ferritin in RA was significantly higher than in healthy controls of both sexes. The levels of ferritin in synovial fluids of patients with 14 RA and with 12 osteoarthritis were 2894±3017 ng/ml and 1429±1005 ng/ml, and no differences were observed in both groups. |

| Title Alternative | Automatic measurement of oxygen isotope ratio of water samples |
| FullText URL | pitsr_056_027_034.pdf |
| Author | Chiba, Hitoshi| Sakai, Hitoshi| Yasutake, Masatoshi| |
| Abstract | The automatic sample preparation system for oxygen isotope analysis of natural water samples was constructed. The system is essentially a modification of that originally designed by W. Dansgaard in the University of Copenhagen. Sixty water samples of 5 ml each are automatically equilibrated with CO(2) of 30 ml NTP each within 4.5 hours. The equilibrated CO(2) gases are successively measured for their oxygen isotopic ratios by an automatic mas-sspectrometer, VG903. The time required for the measurement of the 60 CO(2) samples is about 15 hours; thus approximately 20 hours are required to complete the isotopic measurements of 60 water samples. The accuracy of the oxygen isotopic analyses is about 0.1%. The result of oxygen isotopic analyses by the automatic preparation system agrees with that of the conventional method within about +0.1%. The results indicate that the automatic preparation system is applicable for the oxygen isotope analysis of natural water samples. |

| Abstract | This article investigated into differences between first- and third-year senior high school students concerning: (a) the efficiencies of phonological coding and working memory capacities; and (b) the relationships of these two variables with reading comprehension. Also explored was whether the relationships were reflected in word-retaining strategies of the first-year students in the reading span tests for measuring working melnory capacities. The findings were: (a) students may improve their working memory capacities but may not improve the efficiencies of phonological coding during the first two years of senior high school; (b) the efficiency of phonological coding contributes to reading cOlnprehension more greatly for first-year students, but working metllory capacity contributes to reading comprehension for third-year students; and (c) the word-retaining strategies of first-year students reflect the relationships between the two variables and reading comprehension. The reasons for these findings were discussed and pedagogical implications were shown. |
