The results obtained are as follows.(1) Following microinjection of capsaicin (10μmol/L, 50nl) into the AP, MAP, HR and RSNA were significantly increased from l2.34±0.53 kPa,328.52±7.54 bpm and 100±0% to 15.17±0.25kPa (P.001), 354.81±8.54bpm (P.001) and 156.95±7.57%(P.001), respectively.(2) Ruthenium red (RR, 100mmol/L, 0.2ml, iv), a capsaicin receptor antagonist, significantly inhibited these effects of capsaicin.(3) Pretreatment with a NMDA receptor antagonist MK-801 (500μg/kg, 0.2ml, iv) also reduced these effects of capsaicin.

實(shí)驗(yàn)結(jié)果如下：(1)最后區(qū)內(nèi)注射辣椒素可引起MAP久久精品无码一级二级、HR和RSNA明顯增加中国黄色视频在线观看，分別由12.34±0.53kPa欧美偷拍视频xxxx、328.52±7.54bpm和100±0％增至15.17±0.25kPa（P＜0.001）一级黄色毛片操逼的视频、354.81±8.54bpm(P.001)和156.95±7.57%(P.001)不卡免费黄色小视频；(2)靜脈注射辣椒素受體阻斷劑釕紅(100mmol/L欧美日韩综合久久精品A片app， 0.2ml)后，辣椒素的上述效應(yīng)可被明顯抑制亚洲中久久久久久精品国产；(3)預(yù)先應(yīng)用NMDA受體阻斷劑MK-801(500μg/kg欧美视频视频二区主播大秀， 0.2ml， iv)也明顯抑制辣椒素的興奮效應(yīng)。

The excitatory response to intracarotid injection of capsaicin was significantly inhibited by pretreatment with the vanilloid receptor antagonist ruthenium red (200mmol, 0.1ml), The results indicate that capsaicin may activate the neurons of the brainstem nuclei involved in cardiovascular regulation through vanilloid receptors, but does not exert any effects on PAG and RN.

應(yīng)用辣椒素受體阻斷劑釕紅(RR欧美性爱视频黄片； 200mmol女人与拘性行为视频网站， 0.1 ml)，可明顯抑制辣椒素的上述效應(yīng)久久精品就只有精品99。以上結(jié)果提示九九青草视频，辣椒素可通過(guò)激活辣椒素受體，引起腦干內(nèi)多個(gè)心血管活動(dòng)相關(guān)核團(tuán)的神經(jīng)元興奮影音最新资源在线观看，但對(duì)PAC和RN無(wú)影響网站色色的。
