(1) In mice, intraperitoneal injection of corydalis B (dl-tetrahydropalmatine), 40 mg/kg, potentiated hexobarbital narcosis, and reduced the passive and spontaneous activity in the rotarod, rolling cylinder and photo-electric cage experiments. The hyperactivity induced by small doses of amphetamine and the amphetamine toxicity in aggregated mice were both significantly reduced by this drug. On the motor defense conditioned reflexes in.cat corydalis B had no marked influence in subcutaneous doses of 10—20 mg/kg. At the dosage of 30 mg/kg, the cats exhibited at first excitant behavior (running, jumping, growling etc.) and then depression set in with almost complete disappearance of conditioned and unconditioned reflexes. At the intraperitoneal dosage of 10 mg/kg, the conditioned reflex was abolished partially, whilst the unconditioned reflex remained unaffected. In cats, an intraventricular injection of corydalis B, 1—2 mg/kg, caused changes in aggressive behavior, such as hissing. The cats became calm and drowsy, but could be easily awaken by external stimuli. In normal rabbits, spontaneous electric activity of cerebral cortex was recorded. The low voltage fast activity was the main element in EEG, sometimes α-wave and spindles were presented. Within 3—7 minutes following single intravenous injection of 15—20 mg/kg, the high voltage slow waves (1.5—3 c/s, 250—400 μv) were found, and maintained 5—15 minutes.. At the same time the arousal response in EEG evoked by stimulation on skin with direct current was inhibited. Thereafter, in the lapse of 20—40 minutes, EEG recovered gradually. (2) In mice, corydalis B aggravated the strychnine convulsions, but inhibited the metrazol convulsions. It had some synergetic action with phenytoin. (3) A single subcutaneous injection of 40 mg/kg of corydalis B could antagonize emesis induced by 0.1—0.2 mg/kg of apomorphine, but failed to do so when the dosage of the latter was raised to 1 mg/kg. The emesis caused by copper sulfate was not antagonized by corydalis B. (4) In rats, corydalis B produced a slight hypothermia.

(一)延胡索素乙与环己烯巴比妥钠有协同作用,可以减低小白鼠的被动性和自发性活动;它能对抗小量苯丙胺的兴奋现象,又能明显降低大剂量苯丙胺的毒性反应。它们的有效剂量为20—40毫克/公斤。皮下注射乙素10—30毫克/公斤可使猫先兴奋后抑制,较大剂量对防御性条件反射和非条件反射均能抑制,该作用持续2—3小时以上;腹腔给药时作用情况相似。从侧脑室注射乙素1—2毫克/公斤可使猫消除恐惧跳避的行为,出现瞌睡现象,但易为外界刺激所唤醒。正常家兔的皮层脑电波以低电压快波为主,静脉注射乙素15—20毫克/公斤可使其变成高电压慢波,此时对感应电流刺激皮肤的惊醒反应明显消灭,约历40分钟乙素作用消失。 (二)乙素可使士的宁容易产生惊厥,伹能抑制五甲烯四氮唑的惊厥作用。它不能对抗电休克的发生,略能协同苯妥英钠作用。 (三)乙素略有中枢性的镇吐作用,略能降低体温。

When sodium evipan, sodium pentothal, chloral hydrate, or ethyl alcohol was used, lycorine (12 mg/kg I. P.) might prolong the sleeping time of mice by 2-4 times that of the control group. A very pronounced sedative action was observed when according to Richter's torsion method it was used intraperitoneally to mice with the dose level of 2-10 mg/kg. It lowered the temperature of normal rabbits and rabbits with fever induced by ty- phoid vaccine. It depressed the basal metabolic rate of mice and decreased the...

When sodium evipan, sodium pentothal, chloral hydrate, or ethyl alcohol was used, lycorine (12 mg/kg I. P.) might prolong the sleeping time of mice by 2-4 times that of the control group. A very pronounced sedative action was observed when according to Richter's torsion method it was used intraperitoneally to mice with the dose level of 2-10 mg/kg. It lowered the temperature of normal rabbits and rabbits with fever induced by ty- phoid vaccine. It depressed the basal metabolic rate of mice and decreased the ATP content of the intact hearts of rabbits, both auricles and ventricles (3-12 mg/kg I. V.). Lycorine also inhibited the activity of the kidney succinic dehydrogenase when used intraperitoneally to the mice with the dose, level above 10 mg/kg. It is interesting to note that large amount of ascorbic acid (5-50 mg/mouse I.P.) might potentiate the toxicity of lycorine. This was contrary to what the literature had stated. From the experiments of conditioned reflex on rats and the emetic effect on dogs, it was found that 3 mg/kg of lycorine hypodermically injected was the appropriate dose level for practical significance.

石蒜碱能延长环己烯巴比妥钠、硫喷妥钠、水合氯醛等催眠剂原作用时间达2-4倍;能减少小鼠自发性活动,呈现明显的镇静作用;能增强延胡索乙素、吗啡等镇痛效力;能降低人工发热家兔体温;使乌拉坦麻醉兔尿量显著减少而呈抗利尿现象.通过大鼠条件反射及犬的呕吐反应证明,以3毫克与12毫克/公斤剂量水平的石蒜碱进行药理观察是适当的,前一剂量(3毫克/公斤)更具一定的实际意义.石蒜碱能抑制小鼠的呼吸代谢及肾脏琥珀酸脱氢酶的活力;降低兔心脏中ATP含量.大剂量抗坏血酸能增强石蒜碱的毒性.

Some properties of the peripheral sympathomimetic action of ergometrine were investigated with isolated preparations of guinea-pig hypogastrio nerve-vas deferens and non-pregnant rabbit uterus. Ergometrine strengthened the contractions of the isolated vas deferens elicited by electrical stimulation of the hypogastric nerve, and this action was antagonized by yohimbine and guanethidine, but not by atropine. At a higher concentration ergometrine could induce spontaneous contractions in preparations with or without...

Some properties of the peripheral sympathomimetic action of ergometrine were investigated with isolated preparations of guinea-pig hypogastrio nerve-vas deferens and non-pregnant rabbit uterus. Ergometrine strengthened the contractions of the isolated vas deferens elicited by electrical stimulation of the hypogastric nerve, and this action was antagonized by yohimbine and guanethidine, but not by atropine. At a higher concentration ergometrine could induce spontaneous contractions in preparations with or without pre-treatment, and this effect could not be antagonized by guanethidine. Noradrenaline had similar actions as did ergometrine. But on the contractions induced by direct electrical stimulation of the muscle under hypoxia and cooling, noradrenaline had an inhibitory action instead, while ergometrine still had a strengthening action. On the non-pregnant rabbit uterus, ergometrine also exhibited a sympathomimetic action, which could be antagonized by yohimbine. An intimate relationship between the sensitivity of rabbit uterus to ergometrine and the catecholamine content in the tissue had been shown by the fact that the sensitivity to ergometrine was raised twofold in reserpinised preparations, but lowered three to five times in those replete with noradrenaline or adrenaline.

本文采用V-H标本和未孕家兔子宫,对麦角新碱外周拟交感作用特点,进行了初步探讨。实验资料表明,麦角新碱和去甲肾上腺素的作用在很多方面是相似的:如增强输精管对电刺激下腹神经的反应,阿托品不能对抗它们的这一作用,而育亨宾和胍乙啶则能对抗之,两者引起的V-H标本的自发性收缩不会被胍乙啶对抗,以及它们兴奋家兔子宫的作用可被育亨宾所对抗等;唯一不同之处,就是在低温低氧情况下,麦角新碱能增强输精管对直接电刺激的效应,而去甲肾上腺素则能抑制这一效应,其原因有待进一步探讨。此外,还证明V-H标本和家兔子宫对麦角新碱的敏感性,与组织中儿茶酚胺含量有密切关系,利用利血平排空组织中儿茶酚胺之后,可显著地增敏实验标本对麦角新碱的反应性。
