histological investigation of thermosensitivity in the laryngopharynx.

关于咽喉部的热敏性，目前还没有详细的研究。我们推测过渡端受体潜能(Trp)家族受体与喉咽的温度敏感性密切相关。最著名的受体是香草素受体1型(VR1)，又称辣椒素受体。我们用免疫组织化学方法对大鼠背根神经节和三叉神经的VR1、PV5和PM8进行了染色。在背根神经节和三叉神经中可见VR1和TRPM阳性神经元。

It is not investigated in detail about thermosensitivity of laryngopharynx. We guess transiend receptor potential (TRP) family receptors have an intimate involvement in thermosensitivity of laryngopharynx. Most famous receptor is vanilloid receptor type 1(VR1) that is known as capsaicin receptor.We use immunostaining method with VR1, PV5 and PM8 in dorsal root ganglion and trigeminal nerve of Rat. We found VR1 and TRPM positive neuron cell in dorsal root ganglion and trigeminal nerve.
