体外研究 当髓质用α2肾上腺素能受体拮抗剂Piperoxane(50μM; 5分钟)灌注,而脑桥用人工脑脊液(ACSF)时,三种无活性制剂以低频率(2-4 c/min)显示节律性膈神经爆发,在Piperoxane应用的最后3分钟内,12个活性物质的膈爆发频率显着增加(先前平均频率的163±12%)。在活性髓质制剂中,当ACSF(n = 8)或α2肾上腺素能受体拮抗剂Piperoxane(50μM; PIP-ACSF; n = 5)灌注制剂时,比较NA应用的效果(25μM; 5分钟)。 )。单独的NA应用(NA-ACSF)或与Piperoxane(PIP-ACSF + NA)的NA应用显着增加了膈爆发频率。然而,Piperoxane对延髓α2肾上腺素能受体的阻断增强了膈神经突发频率的增加:在NA应用的第5分钟,当单独应用ACSF时,膈爆发频率达到平均对照值的171±11%,并且234±21%当PIP-ACSF应用于控制条件[1]时的平均控制值。
激酶实验 小鼠新生儿(P0-P3)被乙醚麻醉并去除大脑;解剖出脑干和颈髓,并将腹侧朝上放置在2 mL室内,该室用人工脑脊液(ACSF)灌注,温度为27±0.25°C(平均值±SD),以2 mL / min的速率更新。 ACSF [含有(以mM计)129 NaCl,3.35 KCl,1.26 CaCl 2,1.15 MgCl 2,21 NaHCO 3,0.58 NaH 2 PO 4和30葡萄糖]通过鼓泡碳原子(95%O2-)氧化和平衡(pH 7.4在27°C) 5%CO2)。在药理实验中,它被另一种溶解有生物反应物质的ACSF所取代:25μM的去甲肾上腺素(NA-ACSF)或α2肾上腺素能受体拮抗剂,50μM的Piperoxane(PIP-ACSF)或50μM的育亨宾(YO-学联)。在一些实验中,膜片钳微电极(1μm直径尖端)在腹侧脑桥内降低到A5核中,其中ACSF或NA(1mM)的溶液被压力喷射。对于持续2 s的压力脉冲,估计弹出体积为20 nL [1]。
动物实验 小鼠[2]使用雄性Balb-C小鼠,体重在20至25g之间。在使用α-肾上腺素能受体拮抗剂Piperoxan或纳洛酮预处理的小鼠中,在乙酸前15分钟给予3×10-5 mol / kg sc的剂量,( - ) - 异丙肾上腺素的抗伤害作用仅略微拮抗。剂量比为1.45和1.7,由这两种拮抗剂产生。
