Characterization of the mechanism underlying stonustoxin-mediated relaxant response in the rat aorta in vitro

Stonustoxin (SNTX) is a lethal factor isolated from the venom of the stonefish Synanceja horrida. Although SNTX exhibits a multitude of biological activities, the primary cause of death upon administration of the toxin is attributed to marked hypotension. We investigated the possible mechanisms underlying the vascular hyporeactivity of this novel toxin. Cumulative doses of SNTX (5-320 ng/mL) induced concentration-dependent relaxation in phenylephrine (PE)--precontracted rat aortic rings with intact endothelium. Endothelium removal abolished the relaxation induced by SNTX. Tetraethylammonium (TEA), an inhibitor of K(+) channels, partially inhibited SNTX-induced relaxation. Similarly, SNTX-induced relaxation was partially attenuated by the SP receptor antagonist (NATB), whereas the inducible iNOS inhibitor, AMT-HCl, completely abolished the relaxation caused by SNTX. From the results obtained, it can be postulated that a component of SNTX-mediated vasorelaxation is via binding of either SNTX or SP to the SP receptors that are located on the endothelial cells. Occupation of these SP receptors causes subsequent production of NO and activation of K(+) channels, thus leading to vasorelaxation of the rat aortic rings.     

痛泻要方对肠易激综合征作用机制的实验研究

目的探讨痛泻要方对内脏高敏感性肠易激综合征(IBS)模型大鼠的疗效和作用机制。方法采用结肠慢性刺激法制作内脏高敏感性的IBS大鼠模型。将实验动物分为正常组,模型组,阳性对照(得舒特)组,痛泻要方低、高剂量组。观察各组大鼠肠道内扩张引起腹部抬起和背部拱起的容量阈值和大鼠肠道内不同容量下扩张期间腹壁收缩次数,检测5-羟色胺(5-HT)、P物质(SP)、降钙素基因相关肽(CGRP)水平。结果与模型组相比,各治疗组大鼠行为学和电生理指标均有明显改善;各治疗组模型大鼠5-HT、SP水平明显下降,CGRP水平增加,且有一定的量效关系。结论痛泻药方能降低内脏高敏感性IBS模型大鼠血清5-HT、血浆SP水平,增加CGRP水平,大剂量痛泻药方疗效优于得舒特。痛泻药方的作用机制可能是通过降低模型大鼠血清5-HT、血浆SP水平,减弱背角神经元兴奋性,从而提高内脏痛阈、消除肠道过敏而达到治疗目的。

Effects of tachykinin receptor agonists and antagonists on the guinea-pig isolated oesophagus

1. Vagal nerve stimulation of the guinea-pig isolated oesophagus produced a triphasic tetrodotoxin (TTX)-sensitive contractile response. The third phase, which was resistant to ganglion blocking drugs, was selectively abolished by capsaicin, suggesting the involvement of one or more neuropeptides released from afferent neurons. Receptors on cholinergic neurons were subsequently activated because the response was atropine sensitive. Contractile responses resulting from exogenous substance P were abolished by atropine and TTX and enhanced by physostigmine. These findings suggest that the third phase may be mediated by the action of a substance P-like neuropeptide released from sensory nerve endings that subsequently activated cholinergic neurons. 2. The tachykinin receptors in the body of the guinea-pig oesophagus were characterized by determining the relative agonist potencies of natural tachykinins as well as tachykinin receptor-selective analogues. Antagonist affinities were also determined. The results indicated the presence of both NK2 and NK3 receptors. In addition, the effects of a cocktail of peptidase inhibitors (captopril, thiorphan and amastatin) on responses to various tachykinins and synthetic analogues were determined. The results indicate that one or more peptidases are present in this preparation. 3. Experiments using various tachykinin receptor antagonists were performed to determine whether the activation of tachykinin receptors played a role in the mediation of the third phase of the response to vagal nerve stimulation. While this response was unaffected by NK1 and NK2 receptor-selective antagonists, it was only partially inhibited (23%) by the NK3 receptor antagonist SR 142801. Thus, in the guinea-pig oesophagus, it appears that NK3 receptors play only a minor role in mediating a contractile response when afferent neurons are excited by vagal nerve stimulation.
