Abstract

In urethane anaesthetized rats, electrical, low intensity stimulations using bipolar concentric electrodes or monopolar glass pipettes were applied to SFO and to surrounding structure's populations. Blood pressure, recorded from the femoral artery, was systematically and rapidly increased when the electrical, as well as the mechanical (electrode displacements) stimulations were located within the SFO populations. Remote from the SFO, stimulations either were ineffective or produced non reliable responses. SFO cells seen to be involved in the defense against all hydroionic deficiencies, including those of blood pressure.

摘要

在氨基甲酸乙酯麻醉的大鼠中,使用双极同心电极或单极玻璃微吸管对终板血管器(SFO)及其周围结构群体进行低强度电刺激。当电刺激以及机械刺激(电极移位)作用于终板血管器群体时,从股动脉记录的血压会系统性且迅速升高。在远离终板血管器的部位,刺激要么无效,要么产生不可靠的反应。终板血管器细胞似乎参与了对所有氢离子缺乏情况的防御,包括血压方面的氢离子缺乏。
