体内研究 | GR 82334(鞘内给药;0.1 nmol-1 nmol)在1 nmol但不在0.1 nmol时刺激大鼠无名膀胱,并且局部应用辣椒素(4μg/50μl)可降低反射性化学伤害性[1]。GR 82334(10 nM-1µM;在椎骨L4和L5之间注射)在10 nM处对两种动物都没有影响,在剂量>100 nM时增加小鼠热诱导的足部退缩潜伏期,但在裸鼹鼠中没有这种增加,剂量>100 nM引起潜伏期缩短的趋势[2]。动物模型:3-6月龄雄性C57BL/6小鼠和6-18月龄裸鼹鼠[2]剂量:10nm,100nm,1µM给药:L4和L5椎骨间注射。结果:小鼠热诱导的足退缩潜伏期增加。 |

Effect of tachykinins on ascending and descending reflex pathway in rat small intestine.
Acta Pharmacol. Sin. 23(4) , 289-95, (2002) To examine the effect of tachykinins on the ascending reflex pathway in rat small intestine, we used different selective neurokinin (NK) receptor antagonists (RA): a) NK1-RA: GR-82334 and CP-96.345, b... |

Substance P modulates localized calcium transients and membrane current responses in murine colonic myocytes.
Br. J. Pharmacol. 138(7) , 1233-43, (2003) 1. Neurokinins contribute to the neural regulation of gastrointestinal (GI) smooth muscles. We studied responses of murine colonic smooth muscle cells to substance P (SP) and NK(1) and NK(2) agonists ... |

Characterization of receptors for two Xenopus gastrointestinal tachykinin peptides in their species of origin.
Naunyn Schmiedebergs Arch. Pharmacol. 370(1) , 35-45, (2004) Two tachykinin peptides, bufokinin and Xenopus neurokinin A (X-NKA) were recently isolated from Xenopus laevis. In this study we investigated the tachykinin receptors in the Xenopus gastrointestinal t... |
