Kinase experiment: | The mouse neonates (P0-P3) are ether-anesthetized and decerebrated; the brain stems and the cervical spinal cords are dissected out and placed ventral sides up in a 2 mL chamber superfused with artificial cerebrospinal fluid (ACSF) at 27±0.25°C (mean±SD), renewed at a rate of 2 mL/min. The ACSF [containing (in mM) 129 NaCl, 3.35 KCl, 1.26 CaCl2, 1.15 MgCl2, 21 NaHCO3, 0.58 NaH2PO4, and 30 glucose] is oxygenated and equilibrated (pH 7.4 at 27°C) by bubbling carbogene (95% O2-5% CO2). In the pharmacological experiments, this is replaced by another ACSF in which bioreactive substances are dissolved: noradrenaline at 25 μM (NA-ACSF) or α2 adrenoceptor antagonists, either Piperoxane at 50 μM (PIP-ACSF) or yohimbine at 50 μM (YO-ACSF). In some of the experiments, a patch-clamp microelectrode (1 μm diameter tip) is lowered within the ventral pons into the A5 nucleus where a solution of either ACSF or NA (1 mM) is pressure-ejected. The ejected volume is estimated 20 nL for a pressure pulse lasting 2 s[1]. |
Animal experiment: | Mice[2] Male Balb-C mice are used, weighing between 20 and 25 g. In mice pretreated with the α-adrenoceptor antagonist Piperoxan, or with naloxone, both at a dose of 3×10-5 mol /kg s.c. given 15 min before the acetic acid, the antinociceptive action of (-)-isoprenaline is only slightly antagonized. Dose-ratios of 1.45 and 1.7, are produced by these two antagonists. |

Piperoxan is an α2-adrenergic receptor (α2-AR) antagonist (Kis = 5.4, 2, and 1.3 nM for α2A-, α2B-, and α2C-ARs, respectively) and a first generation histamine receptor antagonist.1,2 It reverses decreases in systolic blood pressure induced by clonidine in spontaneously hypertensive rats when administered at a dose of 10 mg/kg.3

DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
