The electroencephalogram of the toad was found to be composed of a 2—6/sec slow rhythm and low voltage (10—20 μV), 12—18/sec fast waves. Irradiation of the brain with ultrasound (250 watts, 24 Kc) for three minutes could abolish or greatly depress the fast component of the electroencephalogram and leave the slow component essentially unaffected. The fast waves, however, would recover if the period of irradiation did not exceed three minutes. Prolonged exposure of the brain to ultrasound resulted in irreversible...

The electroencephalogram of the toad was found to be composed of a 2—6/sec slow rhythm and low voltage (10—20 μV), 12—18/sec fast waves. Irradiation of the brain with ultrasound (250 watts, 24 Kc) for three minutes could abolish or greatly depress the fast component of the electroencephalogram and leave the slow component essentially unaffected. The fast waves, however, would recover if the period of irradiation did not exceed three minutes. Prolonged exposure of the brain to ultrasound resulted in irreversible EEG changes. The depression of the fast component of EEG under the present conditions could not be attributed to the heat effect of the ultrasound, since the deliberate elevation of the brain temperature by some other means to a degree comparable to that produced by the ultrasound (about 1—2℃) failed to reproduce the EEG changes. Nor could it be interpreted as due to the vascular changes of the brain resulting from the ultrasonic irradiation, since direct observation of the brain surface with a dissecting microscope could not reveal any detectable change in caliber of the blood vessels during irradiation. It was thus concluded that the deleterious mechanical effect of the ultrasonic vibrations on the brain tissue was probably responsible for the observed EEG changes.

(一)蟾蜍的脑电图有快慢两种波型,快波的頻率为每秒12—18次,振幅为10—20微伏,慢波的頻率为每秒3—6次,振幅在30微伏以上,通常以快波为主。 (二)用輸出功率250瓦、頻率24千赫茲的超声波透射3分钟,可使蟾蜍脑电图受到阻抑,表現为快波減弱或完全消失,仅殘存不規則的慢波,但在超声停止作用后45分钟之內即行恢复。延长超声波透射的时間,則可使脑电图出現不可逆的变化。 (三)上述剂量的超声波,仅使蟾蜍脑温增高1—2℃,脑表层血管的血流状态和口径无任何可見的变化。 (四)用外部加温法使蟾蜍脑温自24℃增至35℃时,脑电图无显著变动。 (五)超声波对脑电图的阻抑性影响,不能以其热作用加以解释,可能是其机械作用所致。

The effects of Chlorpromazine on sensorily evoked cortical potential and direct cortical response have been studied in lightly barbiturate anesthetized rabbits.The intravenous injection of Chlorpromazine in doses of 4—5mg/kg could abolish or greatly depress the negative components of these two cortical responses, while the positive components were only slightly affected. The affects of Chlorpromazine under the present conditions could not be attributed to its direct action upon cerebral cortex,since the...

The effects of Chlorpromazine on sensorily evoked cortical potential and direct cortical response have been studied in lightly barbiturate anesthetized rabbits.The intravenous injection of Chlorpromazine in doses of 4—5mg/kg could abolish or greatly depress the negative components of these two cortical responses, while the positive components were only slightly affected. The affects of Chlorpromazine under the present conditions could not be attributed to its direct action upon cerebral cortex,since the direct cortical responses of the isolated cortex were essentially unaffected by the drug. From the results mentioned,it was conjectured that the ascending reticular ativating system may exert its tonic influences mainly on the superficial layers of cerebral cortex. The intravenous injection of Chlorpromazine caused a marked fall in blood pressure.The similarity in the time course between the changes of blood pressure and the cortical responses suggects that the action of Chlorpromazine on reticular formation may also relate to its effect on blood pressure.

一、本工作研究了靜脉注入氯丙嗪对兔皮层体感觉性誘发电位与直接皮层电反应各相成分的影响,并观察了該药对隔离皮层电反应的影响。二、每公斤体重注入4~5毫克的氯丙嗪可使誘发电位与直接皮层电反应的表負波受到显著的阻抑作用.但它們的表正波却受影响不大。誘发电位的次反应(第二正波)亦受到明显的阻抑作用。三、靜脉注入同剂量的氯丙嗪对隔离皮层的直接电反应几乎不发生影响,局部施加氯丙嗪只在浓度很高时始能对皮层电位有阻抑作用。这表明在本实驗条件下,氯丙嗪对皮层电反应的影响不是直接作用皮于层的結果。四、靜脉注入同剂量的氯丙嗪可使血压明显降低,其变化过程与皮层电变化的过程在时程上十分一致,說明氯丙嗪对网状結构上行系統的阻断作用也可能与其对血压的影响有关。五、由上述結果可以推測,网状結构上行激动系統通常主要是对大脑皮层的表层成分发生紧张性影响,以維持与改变其兴奋状态的。

The general layout of a steel plant is a complex standard to measure the level of its design and construction. According to present conditions arrangement of operations between the steelmaking shop and the rolling mills of the plant has great influence upon the general plan of the whole plant.The ingot teeming along the transverse axis of the steel shop (transverse teeming) is better than the ingot teeming along the axis parallel to the shop axis. This is more favourable for future change to continuous casting. If the teeming is designed in continuous casting or in combination of continuous casting and transverse ingot teeming, it is possible to omit the railroad laid in between the steel shop and the rolling mills, at least to reduce the distance between them, to reduce the length of the pipelines, to reduce the area required, in order to cut down investment of the steel plant and its transportation costs. In this way the standard of the general layout would be raised.

总图布置是钢铁厂的综合性技术,是衡量钢铁厂技术水平的一个因素。从目前条件看,炼钢到轧钢之间的布置对总图布置影响很大。当前由于连铸技术不断进步,连铸比将不断增高,横向车铸比纵向车铸易于安排,并有利于将来改成连铸,如果炼钢注锭工艺能采用连铸或连铸加横向车铸,将能取消炼钢至轧钢的铁路,缩短炼钢与轧钢之间距离,减少厂区管线长度、占地面积、建厂费用和运输生产成本。以使我国总图布置设计达到新的水平。
