值得注意的是，正如在新的研究中发现的，麻醉剂对植物也起作用。研究人员发现，当暴露于麻醉剂时，许多植物失去了自主和触摸诱导的运动。金星捕蝇草不再产生电信号，当触摸到触发毛发时，它们的捕蝇草会保持打开状态，生长中的豌豆卷须会停止自主运动，并以卷曲的形状固定下来。 本研究的结果表明，麻醉剂在细胞和器官水平上的作用在植物和动物中是相似的。本研究表明，植物正在成为研究与麻醉剂有关的一般性问题的模型对象，并作为一种合适的人体麻醉替代测试系统。 A new study published in Annals of Botany shows that plants react to anesthetics similarly to the way animals and humans do, suggesting plants are ideal objects for testing anesthetics actions in future. Anesthetics were first used in the 19th century when it was discovered that inhaling ether gas stopped patients feeling pain during surgery. Since then many different chemicals have been found to induce anesthesia. However, despite the fact that many anesthetics have been used over a 150-year period, little is known about how these different compounds with no structural similarities behave as anesthetic agents inducing loss of consciousness. Remarkably, as found in the new study, anesthetics also work on plants. Researchers found that, when exposed to anesthetics, a number of plants lost both their autonomous and touch-induced movements. Venus flytraps no longer generate electrical signals and their traps remain open when trigger hairs were touched, and growing pea tendrils stopped their autonomous movements and were immobilized in a curled shape. The results of this study suggest that the action of anesthetic at cellular and organ levels are similar in plants and animals. This study suggests that plants are emerging as model objects to study general questions related to anesthetics, as well as to serve as a suitable alternative test system for human anesthesia.
