SE-30系列毛细管色谱柱的最佳载气线这范因为13~17cm/s，且在最佳线速度下很好地分离了异戊醇、硝基氯苯、硝基甲苯及二乙苯同分异构体体系。

In pacemaker cells of SA node superfused with the oxygenated K—H solution, MDP, APA, V〓, VDD, RPF and APD〓 were—45±5mv, 48±4mv, 2. 4±0.9v/s, 89±8 mv/s, 200±11bpm and 206±15ms, respectively. Anoxia (perfused for 20min with a modified K—H solution gassed with 100% N〓 and deprived of glucose) increased MDP, APA and V〓, and decreased VDD and RPF in a timedependent manner. At anoxia for 20min, the above parameters were—58±5mv, 64±5mv, 11. 7±2. 7v/s, 24±7mv/s, 92±11bpm and 179± 14ms, respectively. ADase (10U/L).

环戊腺苷和苯基异丙基腺苷不仅能增加豚鼠窦房结起搏细胞APA、MDP和〓，且能减小VDD、RPF和〓在环戊腺苷20nmol／L浓度时，MDA、APA和〓分别增值5.4±0.7mv、7.6±0.9mv和2.4±0.5v／s，VDD、RPF和〓分别降低32±4mv／s、68±9bpm和31±12ms（p.05或0.01）。0.1μmol／L 8—苯茶碱和10μmol／L格列苯脲能明显地抑制环戊腺苷的电生理效应。
