ttx 解釋
河脈毒
  1. So the results indicate that the two mutants have no significant difference in the toxicity of inhibiting mammal neuron sodium channels, and ala20 or ser20 was not the key residue. the two peptide neurontoxins inhibite mammalian voltage - gated sodium channels through a novel mechanism distinct from other known spider toxins such as 5 - actxs, - agatoxins i - vi which banded receptor site 3 to slow the inactive time course of sodium channels. we suggest that hntx - v maybe target the site 1 of sodium channels in a similar manner to - conotoxins and ttx

    同時兩種海南捕鳥蛛毒素從影響ttx一s鈉通道的方式上來看，與其它已知膚類蜘蛛毒素如6一actxs等通過作用於位點3引起延緩鈉通道的失活時間存在明顯不同，我們推測hntx一iv和iintx一v可能是以一種新的不同於其它蜘蛛毒素的方式來影響鈉通道的，而ttx一s鈉通道位點1則很有可能便是它們的作用位點，與ttx和林一eonotoxins相似。
  2. The nociceptin - induced current was not affected by tetrodotoxin ( ttx ; 1 um ; n = 4 ) and also by a non - specific opioid receptor antagonist, naloxone ( 1 um ; n = 4 )

    灌流m （ tetrodotoxm ； lqm ； n 4 ）和納洛酮（阿片類受體的非特異性桔抗劑； l卜n 4 ）均對nociceptin誘致的外向電流也不產生任何作用。
  3. Among them, selenocosmia huwena and selenocosmia hainana belong to theraphosidae while macrothele raveni belongs to hexathelidae. all of them could kill insects and some small vertebrate with their venoms. in this article, using whole - cell patch - clamp technology, we observed the effects of the venoms from the three kinds of spider on the voltage - activated tetrodotoxin - sensitive ( ttx - s ) sodium current and delay - rectified potassium current of undifferentiated ng108 - 15 cells

    虎紋捕鳥蛛（ selenocosmiahuwena ） 、海南捕鳥蛛（ selenocosmiahainana ）和雷氏大疣蛛（ macrotheleraveni ）均是在我國近年來發現的蜘蛛新種，前兩者屬于捕鳥蛛科，而後者屬于異仿蛛科。
  4. Unfortunately, the pharmaceutical industry has so far been unable to successfully develop selective inhibitors for such channels, in part because they closely resemble ttx - sensitive sodium channels, which appear widely throughout the nervous system

    不幸的是，至今制藥界仍未成功研發出這種通道的選擇性抑制劑；部份原因是它與廣泛分佈於神經系統的ttx敏感型鈉通道十分近似。
  5. The pharmacology analysis on the increased current in the single mutant ( sos3 / athkt1 ) indicated that the increased current, possibly contributed by athktl activity, could be inhibited by ttx and ca2 +. it is insensitive to tea * and have the same selectivity to li +. the data suggest that the protein athktl perhaps is a na + - permeable channel

    結果顯示athkt1蛋白介導的電流增大可被ttx和ca ~ （ 2 + ）部分抑制，對k ~ +通道抑制劑tea ~ +不敏感，而，盯甫大月卜二幾月目睜困月周口創七掩呀，匕月目卜位倫大且對li +有相似的選擇性，表明athkti蛋白可能為一種na +通透型陽離子通道，其蛋白活性受到5053蛋白的抑制調節。
  6. The results showed that they had no evident effect of outword delay - rectified potassium current, while they could inhibit ttx - s fast sodium current

    結果表明，三種蜘蛛粗毒對外向延遲整流鉀電流沒有明顯作用，但對ttx - s的快鈉電流表現出較強的抑制效應。
  7.

    首先，本章分析了外匯市場參與者行為，得出國際投機資本是導致匯率不穩定的主體的判斷；然後，本章以匯率不穩定為線索回顧了匯率決定理論的發展；接著，本章從知識、信息與預期形成的角度強調了理性在匯率不穩定中的重要性；最後，本章從國際貿易和銀行信貸兩個渠道分析了匯率不穩定對宏觀經濟運行的影響機制。
  8. Pain - sensing neurons, however, possess a subclass of voltage - gated sodium channels, known as the ttx - resistant type, that do not occur in the cns

    不過，痛覺受器卻擁有一種特別的電位控制鈉離子通道，稱為河?毒（ ttx ）不敏感型，而中樞神經系統里並沒有這一型。
