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.

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) 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.

抄録 Qualitative and quantitative analysis of sinter deposits in a distributing pipe used for seventeen years (Sample No.1) and adhere to bathtub wall for eleven years (Sample No.2 and Sample No.3) in Misasa radioactive hot springs were investigated. The results were as follows ; (1) The color of deposits of Sample No.1 and Sample No.2 was black and the color of deposits of Sample No.3 was white. The metal elements in these deposits were qualitative analysed by spectraspan plasma emission spectrophotometry (SPES) and by fluorescent X-ray spectrometry. Following elements were detected, in Sample No.1 : Na, Mg, Al, K, Ca, Mn, Fe, Cu, As, Sr, Ba, Mo, and Pb, in Sample No.2 : Na, Mg, Al, Si, K, Ca, Ti, Mn, Fe, Cu, Zn, As, Sr, Ba, Pb and Cl and in Sample No.3 : Na, Mg, Al, Si, K, Ca, Mn, Fe, Cu, Zn, As, Rb, Sr, Mo, Ba, S, and Cl, (2) The metal elements in these deposits were quantitative analysed by SPES, atomic absorption spectrophotometry and emission spectrophometry. Following elements were determined, in Sample No.1 ; Mn : 411.6, Fe : 65.7, Ba : 20.0, Ca : 11.9, Na : 5.7, Cu : 4.5, K : 4.2, Sr : 2.9, Zn : 2.6, Mg : 1.4, in Sample No.2 ; Mn : 248.2, Fe : 28.5, Ba : 15.6, Ca : 25.0, Mg : 10.5, Na : 9.3, Cu : 5.4, K : 4.9, Sr: 7.4, Zn : 3.3, and in Sample No.3 ; Ca : 275.2, Sr : 32.4, Mg: 12.4, Na: 18.7, K: 5.0, Mn: 1.7 and Fe: 0.6mg per gram. The main components of these deposits were manganese compounds (Sample No.1 and Sample No.2) and calcium compounds (Sample No.3). Qualitative and quantitative analysis of barium in sinter deposits of Misasa spa was done by authers for the first time. (3) Radioactivity in these deposits were observed by autoradiography. Among the radioactive elements, concentration of radium were 3.41×10(-8) Ci/g (Sample No.1), 4.70×10(-9) Ci/g (Sample No.2) anp 2.36×10(-11) Ci/g (Sample No.3), respectively.

抄録 鉱泉水中のラドンを測定するため,抽出法を省略し,少量の試料水を直接液状シンチレーターに溶解し,液体シンチレーション計数器を用いて放射能を測定し,次いで簡単な計算法により試料水中のラドン濃度を計算する簡易定量法を試みた。本法を用いて一鉱泉水のラドンを反復測定した際の精度は,σ=0.136nCi/l,CV=5.77 % ,(x=2.36n Ci/l)であった。次に本法でのRnの最少検出量は,0.2nCi/lである。原法と本法とを用いて得られた測定値の間には,r=0.996,y=0.818x+0.875なる相関関係が成立した。本法を使用すると,簡単な予備処理後,極短時間内にラドンの測定が可能なため,花崗岩地域の井水,鉱泉水中のラドンを定量するためには,有用な方法である。
抄録(別表記) Radon in mineral waters was determined with simplicity by newly developed method. In this method, 2.0mℓ of water sample was directly mixed with 15 mℓ of Hionic-Fluor in a vial, which was then filled up with additional Hionic-Fluor ; 190 minutes were allowed for the radioactivity to equilibrate. The radioactiviity of Radon was measured by the Liquid Scintillation Counter (Tri-Carb 460C). Radon content was easily calculated with the proposed formula by an electric desk calculater. The reproducibility was proved CV=5.77 % ; the lowest detection limit was 0.2 nCi/l. An adequate correlation was obtained from the results of measurements compared with the original method ; r=0.996, y=0.818x×0.875.
