中文摘要 | 本研究之目的為建立一以螢光染劑 (Di-4-ANEPPS) 為基礎之心臟動作電位即時量測系統,以用於紀錄動作電位之變化。系統係以一543nm (綠光) 的氦氖雷射經光纖導入量測區域,再收集所激發的螢光,經由光電倍增管轉換成電信號及放大後,轉換成數位訊號於電腦中記錄分析,並可同步記錄其它如EKG等訊號。目前此系統原型已成功試用於不同溫度對牛蛙心肌動作電位的影響與不同藥物對兔子心肌作用機制的研究記錄中。 |
英文摘要 | The goal of this study is to measure action potential using fluorescent signal (Di-4-ANEPPS) from isolated-heart in real time. Optic fiber is used to conduct the laser light of a green He-Ne laser to the measuring area, and then re-collected the red emitted light from stained tissue. The fluorescent light signal is detected by using a Photomultiplier tube (PMT). This computerized system can then record data for up to four signals simultaneously, e.g. fluorescent signal, EKG, temperature, etc. This prototype system has been used to test the effects of temperature on bull frog’s isolated heart and the effects of various drugs on rabbit’s preparation. |
