歳から79歳までの各年齢層の健常人1,261例について心電図R-R間隔変動を指標とした自律神経機能検査を行い, IE常参考値および標準予測式を作成した.安静・時, 深呼吸時, バルサルバ試験, 起立試験での心電図R-R間隔をMEコマーシャル製のオートノミックR-100を使用して連続する100心拍で計測し, 平均値, 標準偏差, 変動係数, 最大値と最小値の比などを検討した.自律神経機能検査成績に性差は認められなかったが, 年齢と強い相関が認められたので年齢別の正常参考値をパラメトリック法で算出した.安静時および深呼吸時の100心拍R-R間隔の標準偏差, 変動係数および最大値と最小値の比は加齢に伴って有意に減少した (P<0.01).また多変量解析法により自律神経機能検査の標準予測式を作成し, 信頼の高い (P<0.01) 予測式を得た

Spinach and komatsuna were cultivated with 0,10,15 and 30g N m^<-2> applications in an Ando soil, and the changes of the contents of sugars, ascorbic acid, nitrate and oxalic acid which are the constituents related with the quality of the vegetables, and the relations between the growth (fresh weight), nitrogen status and the contents of these constituents were investigated. Ascorbic acid is contained both in spinach and komatsuna, but oxalic acid is contained at a high level in spinach and at trace levels in komatsuna. Nitrate nitrogen contents increased along with the increase of applied nitrogen, and reached 1.14g (kg FW)^<-1> in spinach leaf petiole and 1.26g (kg FW)^<-1> in komatsuna leaf petiole at harvest with the application of 30g N m^<-2>. In both crops, sucrose content was highest in the plot of 0g N m^<-2>, glucose content was highest in the plot of 10g N m^<-2>, and they were lowered with increased application of nitrogen. Total ascorbic acid (ASA+DHA) content was decreased by increasing the nitrogen application : from 0.74g (kg FW)^<-1> at the plot of 0g N m^<-2> to 0.51g (kg FW)^<-1> at the plot of 30g N m^<-2> in spinach and from 1.00g (kg FW)^<-1> at the plot of 0g N m^<-2> to 0.48g (kg FW)^<-1> at the plot of 30g N m^<-2> in komatsuna. In spinach, the total (water-soluble plus-insoluble) oxalic acid content was increased in the leaf blades and decreased in the leaf petioles along with the increase of nitrogen application, and there was no difference in the whole leaves with the treatments. The contents of sucrose and ascorbic acid were high in the plants in which yield and nitrogen content were low and dry matter content was high. In view of the quality of spinach and komatsuna, the low nitrogen application is better, but the amount of nitrogen application must be determined considering the maintenance of growth and yield.
