概括
提摩尔是成年斑马鱼的有效麻醉剂,为MS-222和eugenol提供了良好的替代品. 研究表明,50毫克/升的提摩尔可以诱导安全的麻醉,并产生最小的副作用.
科学领域:
- 水生动物福利
- 鱼类麻醉剂
- 斑马鱼研究
背景情况:
- 麻醉剂对于负责任的水产养殖和研究至关重要,
- 斑马鱼 (Danio rerio) 是一个关键的研究模型.
研究的目的:
- 评估提摩尔作为成年斑马鱼的新型麻醉剂.
- 为了确定安全有效的麻醉的最佳度.
- 对斑马鱼进行心肺,运动和厌恶效应的评估.
主要方法:
- 对成年斑马鱼进行了度-反应测试 (25-200 mg/L).
- 记录了诱导和恢复时间.
- 评估了心肺功能,运动和厌恶行为.
- 在暴露后测量皮质醇水平.
主要成果:
- 提摩尔度为50和75毫克/升,诱导了有效的麻醉,诱导时间约为300秒,恢复时间为400-500秒.
- 在有效度下没有观察到死亡,但发生过渡性心肺衰竭.
- 较高的度 (> 150 mg/ L) 诱导了厌恶反应,并且安全边缘很窄.
- 经过10分钟的50mg/L的暴露,皮质醇水平与尤金醇相比较,低于对照水平.
结论:
- 对于成年斑马鱼来说,50mg/L是有效的,有意识的麻醉剂.
- 蒂莫尔可以替代现有的麻醉剂,具有类似的诱导作用,但恢复时间更长.
- 需要进一步研究才能充分了解斑马鱼的生理作用和机制.

CNS Depressants: Barbiturates and Benzodiazepines
CNS depressants include drugs from the category of barbiturates and benzodiazepines. They are valuable medications for managing anxiety disorders and insomnia. Barbiturates, once used to induce and maintain sleep, have been replaced mainly by benzodiazepines due to barbiturate's toxicity, tolerance, and overdose risks. They interact with GABAA receptors, leading to sedation at low doses and potentially coma and death at higher doses. Phenobarbital, a long-acting barbiturate, possesses...
Sedatives and Hypnotics: Overview
Sedatives are drugs that alleviate anxiety, while hypnotics induce sleep. Both classes of medication suppress neuronal activity, leading to a calming effect for sedatives and facilitating sleep for hypnotics.
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

Sedatives and Hypnotics Drugs: Barbiturates
Sedatives and hypnotics encompass a drug class that acts on the central nervous system (CNS) to alleviate anxiety, promote relaxation and induce sleep.These drugs function by amplifying the actions of the neurotransmitter γ-aminobutyric acid (GABA), resulting in reduced neuronal activity. Barbiturates, a subset of sedatives and hypnotics first synthesized in the late 1800s, are categorized into ultra-short, short, intermediate, and long-acting groups based on their duration of effect. A key...
Sedatives and Hypnotics Drugs: Benzodiazepines
Benzodiazepines have both sedative and hypnotic properties. They include compounds such as diazepam (Valium) and alprazolam (Xanax). Structurally, their cores are similar, consisting of the fusion of a benzene ring and a diazepine ring, but they share a common mechanism of action in the central nervous system (CNS).
Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
