Abstract

Field potentials and the reflection spectra of cytochromes were continuously recorded from the olfactory cortical slice of a guinea pig which was incubated under the normoxic and anoxic conditions. The reduction of the oxidated spectra of the cytochromes occurred before the decrease of field potential heights and the oxidation of the reduced spectra occurred before their recovery. In a 3 min anoxic experiment, a 90% recovery of the cytochromes aa3, b, and c, and the field potential amplitudes took place in this order after the restoration of oxygen.

摘要

在常氧和缺氧条件下孵育的豚鼠嗅皮质切片中,连续记录场电位和细胞色素的反射光谱。细胞色素氧化光谱的还原在场电位高度降低之前发生,还原光谱的氧化在其恢复之前发生。在3分钟的缺氧实验中,恢复氧气后,细胞色素aa3、b和c以及场电位幅度按此顺序实现了90%的恢复。
