IPD® (supratast tosilate) was investigated for its prophylactic efficacy and therapeutic efficacy in the treatment of cedar pollinosis during the 1996 cedar pollen season. The subjects investigated were patients at the Gifu University School of Medicine and its affiliated hospitals, who had a history of cedar pollinosis. The patients were classified into two treatment groups: the prophylaxis group (70 patients), in whom IPD® administration began before the start of cedar pollen dispersion, and the treatment group (49 patients), who underwent IPD® treatment only after cedar pollen dispersion had begun and symptoms of pollinosis had manifested.Results were as follows: (1) The nasal symptoms (sneezing, runny nose, nasal congestion) were milder in the prophylaxis group than in the treatment group throughout the cedar pollen season, with the difference being significant during the season's first 2 weeks. (2) In the prophylaxis group, IPD®'s inhibitory effect was rated as excellent in 18.6% of the patients, good in 45.7% and fair in 20.0%. In the treatment group, the improvement in the symptoms was rated as disappearance in 4.2%, excellent in 20.8% and good in 43.8%. (3) When symptom inhibition in the prophylaxis group was investigated as a function of the duration of IPD® administration prior to the start of pollen dispersion, the good + excellent inhibition rate was 57.7% in the subpopulation pretreated for <2 weeks (26 cases), 64.9% with 2 to <4 weeks' pretreatment (37 cases) and 85.7% with 4 to <6 weeks' pretreatment (7 cases). Thus, IPD®'s prophylactic inhibitory rate increased with the length of the pretreatment period. (4) In the prophylaxis groups, the CAP-RAST value was significantly reduced at the time of peak pollen level and at the end of the pollen season compared with the value before IPD® administration.

阿武隈高地のまさ土を対象にして, コンクリート用細骨材への利用について検討した. 細骨材としての品質を評価すると, 規定値をすべて満足するのは絶乾密度, 粘土塊量, 有機不純物量, 吸水率および塩化物に対する安定性は強熱減量Li≦2.5%の場合, 洗い試験はすべてのまさ土で満足しないことがわかった. まさ土を骨材としたときの圧縮強度はセメントの物理試験による強さ試験で行い, 粒度分布を自然粒度と細骨材として規定されている粒度範囲の中央粒度の2種類, 水セメント比は3種類で行つた. その結果, 圧縮強度は粒度分布より水セメント比の影響を強く受けることが明らかになつた. また, 配合設計により強度試験を実施した結果, 設定した圧縮強度の60~110%程度の強度発現が得られ, 圧縮強度はLiに強い影響を受けることがわかった.
