本文采用原位杂交、免疫组织化学方法检测了接受足底电击结合噪声应激刺激5天的大鼠延髓、尤其是延镌头端腹外侧区(rostral ventrolateral medulla, rVLM)编码肾上腺髓质素(adrenomedullin,ADM)的肾上腺髓质素前肽原(preproadrenomedullin,ppADM)mRNA表达和ADM免疫活性(adrenomedullin immunoreactivity,ADM-IR)变化,并通过电刺激中肭导水管背侧周围灰质(dorsal periaquaductal gray of midbrain,dPAG)诱发防御性心血管反应,以及于rVLM微最注射大鼠ADM(rat adrenomedullin,rADM)及其特异性受体拮抗剂--人肾上腺髓质素(22-52)[human adrenomedullin22-52,hADM(22-52)]相结合的手段研究rVLM中ADM在...

In this study, we used techniques of in situ hybridization, immunohistochemistry, electric stimulation of the dorsal periaquaductal gray of the midbrain (dPAG) and microinjection to investigate the changes of preproadrenomedullin (ppADM) gene expression encoding adrenomedullin (ADM) and ADM-like immunoreactivity (ADM-IR) in the medulla oblongata, especially in the rostral ventrolateral medulla (rVLM) of the rats receiving foot-shock and noise stress for 5 d, and the potential role of ADM in cardiovascular component of defense response in the rVLM. The results showed that ppADM mRNA and ADM-IR ...
