Abstract Uric acid was measured in serum and urine of the ambulant and hospitalized patients with various disorders including gout. in Misasa-Branch Hospital of Okayama University Medical School from January 1975 to December 1976. Serum and urine samples were obtained from 283 males and 260 females, and from 2 males respectively. The results are as follws; (1) Uric acid in males was 1.4 mg/100mf higher than in females. (2) Uric acid in males decreased with ages, showing two peaks between 15 and19 , and between 35 and 44 years old. (3) Uric acid in females showed low levels between third and fifth decades and increased thereafter with ages. (4) There were many fatty subjects among the patients with gout. (5) An increase in total daily excretion of urinary uric acid was observed concomitantly with increased daily urine volume. (6) Periodical fluctuations of uric acid in serum and other clinical findings were show in several cases of gout, who had been controlled in MisasaBranch Hospital for several years.

Abstract A plasma emission spectrophotometer "Spectraspan" (low power d. c. plasma arc, operating on argon) was evaluated for boron determination in thermal waters. The influence of acids (hydrochloric, nitric and sulfuric acids) and several metallic ions (Na(+). K(+), Mg(2+). Ca(2+)) on emission intensity was studied. There was a linear relationship between emission intensity and boron content from 0 to 500 mg/l. Boron in thermal waters was easily determined by standard addition method. Precision. coefficient of variance and recoveries of known amount of boron added to the sample for 11 repricate analyses were 0.12μg/ml, 2.02%, 95.0-101.7%, respectively. Boron content of 27 thermal waters in the Sanin district was determined. and the highest B content in the sample waters were 8.8 mg/l (Tottori spa) in Tottori Prefecture and 14.6-25.0 mg/l (the thermal springs at the foot of Mt. Sanbe. a non-active quaternary volcano) in Shimane Prefecture. The relationships between B content and water temperature, B content and pH value were not recognized. Significantly positive correlationship was observed between Band Li contents.

Abstract Sinter deposit in a distributing pipe used for about fifteen years in Misasa radioactive hot springs was investigated. The results were as follows; 1. The metal elements in this deposit were quaIi. tatively analysed by spectraspan plasma emission spectrophotometry (SPES), by fluorescent X-ray spectrometry, and following elements were detected; B, Na, Mg, AI, K, Ca, Mn, Fe, Cu, Zn, As, Sr, Ba and Pb. 2. The metal elements in this deposit were quantatively analysed by SPES and atomic absorption spectrophotometry, and following elements were determined; Fe : 508.7, As: 26.40, Ca: 7.85, Mn : 2.00, Al : 1.80, Na: 1.60, Zn: 1.33, K: 0.80, Cu: 0.67, Sr: 0.47, Mg: 0.35, Ba: 0.33 and B : 0.30 mg per gram. The color of this deposit was red brown, and the main component was ferric oxide. 3. Radioactive elements in this deposit were detected by autoradiography and radioluxography. Among the radioactive elements, concentration of radium was 320.5×10(-12)g/g (313.0×10(-12)Ci/g).

Title Alternative The determination of uric acid using modified Patel's method

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.
