发布时间：2007-07-25
至1989年以来, 采用 Living Systems 压力肌动图进行血管生理及药理研究的全世界顶尖的研究机构和大学及药厂研究室已达五百余家。 生命科学实验研究发表的科学论文2011年已达一千多篇。

线性肌动图通常被用于监测微小血管环 (血管內徑 100毫微米-3毫米)或肌肉条在药物或电刺激下张力 改变的状况（包括主动脉, 阻力微血管,气管,支气管 環、 肌肉、回腸和子宮肌條等). 肌動圖也可用于在監測血管張力和肌細胞張力的同時監測細胞膜電位的改變和組織螢光物質的測量.
應用范圍
基本特性: 小血管, 大血管, 血管壁厚度的測量,兩個血管的對比研究,不同种類的動物血管對比研究及其同類動物不同血管的對比研究,對局部血管反應性的評估, 人體不同血管的研究 .
血管反應机理的研究: 血管內皮：血管內皮分泌的舒張因子（一氧化氮）, 前列腺素以及血管內皮分泌的超极化因子
平滑肌:鈣通道、鉀通道的作用机理
受體研究: 受體定位和作用特征研究, 激素,神經遞質及其它激動劑的影響
药物机理的研究 :ＡＣＥ一抑制劑, 洋地黃及其胰島素作用机理的研究
生理學研究 : 年齡, 怀孕, 麻醉
病理學研究: 高血壓, 脂肪沈滯性動脈硬化症, 糖尿病, 缺血症, 腫瘤, 心臟病, 肺疾病
深入研究的可能性: 電生理實驗(膜電位的測定), 細胞內离子和其它物質的螢光測定
肌動圖系統包括以下几個部分:
•精工制作的在恆溫控制下的微小實驗小室；
•水平位的組織固定支架及其微細調控系統；
•精确的等張力傳感器和高度敏感的張力放大系統；
•信號采集和計算机記錄,分析數椐硬件和軟件系統。
In some cases, such as when using expensive peptides or other drugs, bath superfusion is not an option. These applications call for minimizing the volume of bath fluid to keep the amount of reagents used to a minimum. In these cases, heating the bath to physiological temperatures can be problematic. However, with our wire myograph chamber (MYO-CH) and temperature controller (TC-09S), you can heat the wire myograph chamber directly to physiological temperatures. This package contains everything needed to conduct these self-heating studies in our wire myograph chamber.
Dual Vessel Chambers - Separate baths, 3-8 ml. Removable covers for control of gas environment above each bath. Holder provided for pH electrode (Model PH/E1) for measurement in either bath. Add /S to model number to add Pt stimulation electrode option for electrical neurotransmitter release from the nerve varicosities.

Model CH/2/B/SH - Supplied heat controller (Model TC-03) sets and regulates both bath solution temperatures (<± 1 °C) thus eliminating the need for bath superfusion. For example, in experiments using a buffer such as HEPES, the amounts of peptides, or other expensive agents required to bathe the vessel will be minimized.
An external, heated superfusate can also serve to warm the bath buffer solutions.
An external, heated superfusate can also serve to warm the bath buffer solutions.
Model CH/2/B – Requires external, heated superfusate to warm the bath buffer solutions. Switch selects desired bath thermistor output for monitoring temperature.
NEW Option – Hand Rest Platform – Facilitates both vessel dissection and the tying of vessels to cannulas by holding Petri dish or chamber fixed. Reduces hand strain. (See Peripherals).
