Statistical experimental design is applied to set up quantitative atomic resolution transmission electron microscopy experiments. In such experiments, observations of the atomic structure of the object under study are always subject to spontaneous fluctuations. As a result of these fluctuations, the precision with which structure parameters can be measured is limited. The purpose of the proposed statistical experimental design is to find the experimental settings resulting into the highest attainable precision., Applied Sciences

松果体除去が副腎髄質アドレナリン細胞のゴルジ装置に及ぼす影響を計量的電子顕微鏡的に検索した.正 常対照(NO)秤,手術対照(SX)秤,松果体除去(PX)群の計58匹の雄性ラットを24時間明暗(12:12)周期, 恒温(22±2oC)下に飼育し,術後14日の53日齢に日内8時点で用いた.髄質の通常の電顕標本を作製し,アドレ ナリン細胞全体を倍率3,000倍で,そのゴルジ装置を10,000倍で写真撮影し計測に用いた.ゴルジ装置の体積密度 は1日全体でNO群よりもSX群(P<0.03)とPX群(P<0.025)で高値であった.平滑小胞の数密度は暗期に おいてPX群でSX群よりも高値(P<0.05)を,逆に被覆小胞の数密度は暗期においてSX群でNO群(P< 0.02),PX群(P<0.02)よりも高値を示した. このようにアドレナリン細胞のゴルジ装置は小胞の種類により異 なる影響を松果体から受けるらしい
