The basic electrical rhythm (BER) was studied in situ in the jejunum in 14 anaesthetized mongrel dogs by the mean six monopolar electrodes. The BER frequency was measured in the intact intestine and after proximal and distal transections of the gut 5 cm apart from the electrodes. No significant differences were found between the BER frequencies recorded by each electrode, demonstrating the existence of a frequency plateau which remained after each transection. In the intact intestine the frequency in the plateau was 13.2 +/- 0.3 cpm2. After the proximal transection, this frequency dropped to 12.0 +/- 0.4 cpm (p less than 0.05) and, after the distal transection, it dropped to 10.9 +/- 0.4 cpm (p less than 0.005). This last frequency change shows the influence of the distal intestine on the electrical behaviour of the jejunum.
采用平均六个单极电极，对14只麻醉杂种犬的空肠进行了基本电节律（BER）的原位研究。在完整肠段以及在距电极5厘米处对肠道进行近端和远端横断后，测量BER频率。各电极记录的BER频率之间未发现显著差异，表明存在一个频率平台，每次横断后该平台依然存在。在完整肠段中，平台期频率为13.2±0.3次/分钟。近端横断后，该频率降至12.0±0.4次/分钟（p<0.05），远端横断后，降至10.9±0.4次/分钟（p<0.005）。最后一次频率变化显示了远端肠段对空肠电活动的影响。
