孤立的心脏套件

在这我ab, learners use the isolated biventer cervicis muscle from a chick to investigate how the curare poison affects muscle contraction, and which drugs may work as an antidote to curare.

在这我ab, learners use a guinea pig atria to examine how isoprenaline, propranolol, acetylcholine, atropine, and physostigmine affect the frequency and strength of myocardial contraction.

在这我ab, learners use an isolated phrenic-innervated diaphragm muscle preparation to investigate how suxamethonium, tubocurarine, and edrophonium affect neuromuscular transmission.

在这我ab, learners use an isolated rabbit heart to investigate the effects of epinephrine, norepinephrine, isoproterenol, isoprenaline, acetylcholine, lidocaine, ouabain and a low potassium solution on heart rate and the force of contraction.

在这我ab, learners will apply repetitive electrical stimulation to the sympathetic nerves of the isolated rabbit jejunum. This electrical stimulation inhibits rhythmic output from the enteric nerve plexuses, which in turn leads to relaxation of the intestine and reduced gastrointestinal motility. They will also investigate how the drug guanethidine prevents the release of norepinephrine from sympathetic ("adrenergic") nerve terminals.

在这我ab, learners will examine the effects of oxytocin and epinephrine on an isolated uterus, investigating the effects of a high potassium solution and both beta-adrenergic agonists and antagonists on uterine smooth muscle (myometrium).

在这我ab, learners will use a guinea pig ileum preparation to investigate how codeine, naloxone, naltrexone, norepinephrine, and acetylcholine affect gastrointestinal motility.

在该实验室中，学习者使用刺激的大鼠VAS递延剂来研究突触前起作用并测试这些药物对突触传播的作用的药物。他们还研究了一系列肾上腺受体激动剂和拮抗剂的影响。

在这我ab, learners use an isolated toad rectus abdominis muscle to investigate the effects of tubocurarine and suxamethonium on muscle contraction stimulated by acetylcholine application.

在这个实验室中，学习者检查了各种药物对未刺激的豚鼠发育的影响。学生还检查了两种神秘药物的影响，并确定其作用机理。

在这我ab, learners use an isolated rat vas deferens to investigate the effects of alpha adrenergic receptor agonists and antagonists, and drugs that affect the amount of norepinephrine in the synaptic cleft.

在这个实验室中，学习者在恒定流动下灌注大鼠的孤立后躯。从维持这种流动所需的压力变化中，记录了血管阻力。尽管许多药物对血压有影响，但这可能是由于对心脏（流动变化）或血管床（耐药性变化）的主要作用。为了清楚地定义心血管系统中的作用部位，通常有必要使用简化的制剂，例如大鼠后肢。

在这我ab learners will use arterial rings from a pig coronary artery to explore some drug effects. Arterial rings can be used to demonstrate classical responses to autonomic drugs on vascular smooth muscle. Arterial rings can also be used to show the recently-discovered role of the endothelium in modulating vascular responses.
