氨基甲酸乙酯

Objective To observe the applied effects of combining urethane with procaine in experimental anaesthesia of rabbits.

目的 观察氨基甲酸乙酯与普鲁卡因联合应用在实验兔中的麻醉效果。

The central integrative part of the baroreflex receives afferent information not only from the sino-aortic baroreceptors, but also from various other sources. The present study was to investigate the effect of somatic nerve stimulation on baro-reflex. The exoeriment was performed in α-chloralose-urethane anesthetized rabbits. Intrasi- nusal pressure -mean arterial pressure res- ponse curves were constructed.

在自然状态下，各种传入冲动汇集中枢，很多传入冲动都可影响压力感受性反射，使压力感受性反射受到调制而发生重新调定·本实验旨在观察刺激躯体神经对压力感受性反射的重调定并分析其机制·实验在α-氯醛糖和氨基甲酸乙酯混合麻醉的家兔上进行，利用颈动脉窦灌流技术测量不同窦内压时体循环平均动脉压的水平，并画出窦内压-体循环平均动脉压反应曲线。

If you are using urethan enhanced printing, coating after 8 h of natural drying, you can use water-based ink business card printing and membership card.

如果用氨基甲酸乙酯强化印版，涂布后经过8h的自然干燥，即可使用水性油墨制卡和会员卡制作。

Because you want to use water-based ink, paint, or urethan, phenol-formaldehyde resin on the printing plate for water resistance.

因要使用水性油墨，所以要用漆或氨基甲酸乙酯、酚醛树脂对印版进行耐水强化处理。

After treatment with the above hormones, the rats were established anesthesia with urethan (1g/kg, i. p.); polyethylene catheters were inserted into the external jugular vein and the common carotid artery for drug administration, and then blood pressure was recorded. The arterial catheter was connected to a pressure transducer, and the blood pressure was displayed on the channel of BL-310 Experimental System of Biological Function through IBM computer. We assessed the changes of resting arterial blood pressure, the pressor responses of angiotensin Ⅱ(Ang Ⅱ, 0.01mg/kg), noradrenaline (NA, 0.01mg/kg) and adrenaline (Adr, 0.016mg/kg). The depressor responses of Ach (0.006mg/kg) and carotid sinus baroreflex were also discussed after treatment with the hormones in OVX rats.

用不同雌激素处理21天后，将动物用25％的氨基甲酸乙酯腹腔麻醉（1g／kg），做颈总动脉插管，通过压力换能器，将血压变化输入计算机，通过BL-310智能型生物信号显示与处理系统的压力测定模块，观察去势鼠及不同雌激素替代治疗大鼠静脉注射血管紧张素Ⅱ（AngⅡ，0.01mg／kg）、去甲肾上腺素（NA，0.01mg／kg）、肾上腺素（Adr，0.016mg／kg）的升压反应以及乙酰胆碱（Ach，0.006mg／kg）的降压反应和压力感受性反射的变化。

Methods:Urethan water solution was administered by intraperitoneal injection to induce lung tumor nodes in the male offspring of A6 transgenic mouse, in which the NS gene is expressed in the lung.3-methylcholanthrene benzol solution was administered by subcutaneous injection at left scapular region to induce tumor in the female offspring of A6,in which scapular NS gene was not expressed.

给予肺组织表达非结构基因的首建者转基因小鼠A6子代雄性鼠腹腔注射氨基甲酸乙酯水溶液，以诱发肺瘤结节。

The extremities were titanic, and there was no response to touch stimulations.Our results suggested that Pentobarbital sodium inhibited neuronal firing through GABA_A receptors, therefore the local field potentials and neural firing rates were inhibited; Urethane acted on many kinds of receptors including inhibitory and excitory ones, so the local field potentials did not change significantly; however, because of the multiform receptors on the neurons, the changing of firing rates to different neurons were not the same; Ketamine mainly acted on the NMDA receptors, therefore the local field potentials and neural firing rates were enhanced, and most neural firing rates would be increased.

从这三种麻醉剂的底层作用机制来看，戊巴比妥钠通过作用于GABAA受体对神经细胞发挥抑制性作用，因此表现为场电位和神经元放电的降低；氨基甲酸乙酯同时作用于多种受体通道，既有兴奋性受体，也有抑制性受体，因此，对场电位的影响不大，但对单个神经元来说，每个神经细胞上的受体通道分布差异较大，因此，单个神经元的放电频率变化会有所不同；盐酸氯胺酮主要作用于兴奋性的NMDA受体，故整体场电位活性增加，多数神经元的放电频率也会有所升高。

Spontaneous discharges of the rostral ventrolateral medulla neurons were extracellularly recorded by multi-barrelled microelectrodes in urethane-anesthetized rats.

实验用多管微电极细胞外记录氨基甲酸乙酯麻醉的SD大鼠延髓头端腹外侧区神经元的活动。

The unit discharge of auditory neuron in the cortical AⅠ area was recorded with the extracellularly recording method. The character of ON-OFF responses induced by short pure tone and the influence of stimulating lateral amygdaloid nucleus on these responses and the tuning curves of the recorded neurons were examined.

The effects of electrical and chemical stimulation of the vertral medial area of nucleus facialis on the myoelectric activities of genioglossus were observed in 26 urethane-anaesthetized and vagotomized rabbits.

本研究在26只氨基甲酸乙酯麻醉、断双侧迷走神经的健康成年家兔上观察了电、化学刺激面神经核腹内侧区对颏舌肌肌电活动的影响。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
