To evaluate the effect of natto and soybeans on postprandial blood glucose level, a crossover study was conducted in 12 healthy male volunteers.Subjects were given a control meal (white rice), a natto meal (white rice with natto), or a soybean meal (white rice with steamed soybeans), and blood glucose level in each group was measured before and 15, 30, 45, 60, 90, and 120 minutes after intake.After both the soybean and natto meals, the blood glucose level at 60 minutes after intake was significantly lower than after the control meal. However, only the natto meal, and not the soybean meal, significantly suppressed the rise in blood glucose level at 60 minutes compared to the control meal. Furthermore, the area under the glucose curve from 0 to 120 min after the natto meal was significantly smaller than for the control meal.These results suggest that natto is useful for the control of postprandial blood glucose level.

光注入によりカオス発振する半導体レーザー(LD)を考え,LDの駆動電流に複雑な信号を印加することでカオス発振LDの軌道不安定性を制御する手法を提案した。まず,印加信号として疑似ランダム信号を用いたときLD系の軌道不安定性が向上することを示した。次に印加信号の周波数帯域に対する軌道不安定性の周波数応答について調査し,この周波数応答がLD系のカオススペクトルと一致することを発見した。さらに,カオス信号を印加した場合と,同様なスペクトルを持つような疑似ランダム信号を印加した場合の軌道不安定性を向上させる効果を比較した。これにより,印加信号のスペクトル形状が軌道拡大率の向上の要因であることを示した。
