摘要

在孤束核、最后区、延髓腹外侧头端区和中缝苍白核可见Fos蛋白样免疫阳性反应(FLI)神经元分布,且其数量随ISP升高而增多。在给定ISP下,颈动脉窦内灌流Ado,可使上述区域中FLI表达明显增多。

Abstract

The results showed that Fos-like immunoreactive (FLI) neurons were distributed throughout nucleus tractus solitarius, area postema, rostral ventrolateral medulla and nucleus raphe pallidus, and the number of FLI was increased with the elevation of ISP. Furthermore, perfusing the carotid sinus with Ado at a given ISP markedly increased the FLI in the above regions.

Key words: cfos;Intrasinus pressure;Adenosine
