JOURNAL FREE ACCESSThe activation method of determination of trace amounts of Hg in human urine has been studied by introducing a simple amalgam deposition method. Human urine samples were obtained from the alkali chloride electrolysis plant equipped with Hg cells. The capacity of Cu powder for Hg quantity, the pH conditions, and the shaking time were described. The results showed that the Hg contents in workers' urine samples varied from 33 ppb to 600 ppb depending on working conditions.View full abstractDownload PDF (334K) -

JOURNAL FREE ACCESSThe effect of added substances was studied on the yield of glutamic acid produced by γ-ray irradiation of 2-oxoglutaric acid and ammonia in aqueous solution. The contents of amino acids in the irradiated solutions were determined with amino acids analyzer. Sodium nitrate, allyl alcohol or sodium formate was used as an added substance. The yield of glutamic acid significantly decreased by the addition of nitrate, and it was little affected by the addition of allyl alcohol. In the presence of formate the yield increased from G=0.4 (2-oxoglutaric acid 0.05M and ammonium hydroxide 2M) to G=1.1. As a result, it was found that hydrated electron contributes on the formation of glutamic acid, but hydroxyl radical does not. The yield showed a maximum at ca. 0.1 M ammonium hydroxide concentration. These facts indicate that NH2 radical does not contribute to the formation of glutamic acid. As a reaction mechanism, it can be explained that 2-oxoglutaric acid which had been reduced by hydrated electron reacts with ammonia.View full abstractDownload PDF (464K) -

JOURNAL FREE ACCESSRadiolysis of 0.05% aqueous solution of benzyl alcohol with 60Co γ-rays ranging from 1×104 to 7×105 rad was investigated, in order to presume the change of it contained in radio pharmaceuticals. For both O2 free and oxygenated solutions, an approximately linear relationship holds between the retaining benzyl alcohol and dose in the range from 1×105 to 7×105 rads. The G (-M) values of benzyl alcohol calculated from the relation were 2.34 in the absence and 1.92 in presence of oxygen. In the presence of oxygen, a main product was benzaldehyde and its G value was 0.87. In the absence of oxygen, the main products of the radiolysis were dibenzyl, benzyl phenylcalbinol and hydrobenzoin, which were regarded as the radical-reaction products of PhCH2 and PhCHOH, and the yield of benzaldehyde was negligible. Irrespective o f the presence of oxygen, o- and p-hydroxylated products of benzyl alcohol were found only in small quantity.View full abstractDownload PDF (690K) -

JOURNAL FREE ACCESSThallium-201 has been suggested as a useful diagnostic agent for myocardial scanning. We report herewith the clinical usefulness of T1-201 as a result of our animal studies with rats as well as clinical trial for human being.
After intravenous injection, we killed rats at regular intervals, then measured the activity in each anatomized organ by γ-well counter and observed the internal distribution and examined autoradiograms with the naked eye.
As a result, the accumulation of T1-201 in the myocardium observed in 5 min after injection, reaching the maximum level in 30 min and gradually decreased hereafter.
We performed 22 myocardial clinical scans. In adults we could clearly detect the lesion of myocardial infarction, but in children found it difficult to obtain fully sufficient information due to small heart size and high pulse rate.
Judging from the foregoing we think it possible to obtain much clearer images by using a data analyzer.View full abstractDownload PDF (6973K) -
