The initial surface negative potential elicited by direct electrical stimulation of the cerebral cortex,to be subsequently called for the sake of briefness the direct response,and the first surface negative wave in the cortical response to the antidromic stimulation of the pyrami- dal tract,to be briefly called the antidromic response,are now generally regarded as both representing the activity of the apical dendrites of the pyramidal neurons.We had tested in the rabbit for possible interactions between the...

The initial surface negative potential elicited by direct electrical stimulation of the cerebral cortex,to be subsequently called for the sake of briefness the direct response,and the first surface negative wave in the cortical response to the antidromic stimulation of the pyrami- dal tract,to be briefly called the antidromic response,are now generally regarded as both representing the activity of the apical dendrites of the pyramidal neurons.We had tested in the rabbit for possible interactions between the direct response and the antidromic response when they were made to overlap in time,but found none.Application of procaine to the cortical surface was found to affect the direct response earlier than the antidromic response.With unipolar microelectrode inserted from the surface downwards by small steps into the cortex,the direct response decreased from the very beginning,while the antidromic response at first showed an increase.All these suggest that the direct response and the antidromic response,even though both representing the activity of the apical dendrites, must nevertheless occupy different locations on this structure.It appears that the direct response set up in the terminal portion of the apical dendrites does not conduct towards the basal portion and that likewise the antidromic response reflecting the invasion of impulse to the basal portion, does not travel upwards to the terminal portion. The direct response may be led off from the immediate neighborhood of the stimulating electrodes or several,say 6 mm away.For convenience of description,we called the former“near”response and the later“far” response.We had found that the“near”and“far”responses showed parallel changes under the influences of various drugs.The“far”response could be shown to be a pure post-synaptic response.As the“near”res- ponse appeared to possess the same pharmacological properties as the “far”response,it was inferred to be also a pure post-synaptic response. This tends to support the idea that the terminal portion of the apical dendrites is probably electrically inexcitable.

本文用大脑皮层表面的直接刺激和锥体束逆行刺激,在锥体神经原顶端树状突唤起电反应。各种试验设计以进一步了解顶端树状突末端的传导和兴奋特性为中心目的,主要结果如下:(一)直接刺激在大脑皮层引起的第一个表面负电位和锥体束逆行冲动在大脑皮层引起的第一个表面负电位虽都代表顶端树状突的活动,但可以同时出现而不互相干扰。(二)在局部施加普鲁卡因溶液后,以及用微电极在皮层不同深度作单极引出时,这两个负电位不呈现平行的变化。(三)用一对尖端上下距离为0.3—0.7毫米的钢丝微电极垂直地插入皮层记录,看出直接刺激皮层表面引起的第一个表面负电位是局限于皮层近表面层,而锥体束刺激所引起的第一个表面负电位并不到达皮层近表面层。(四)我们同时在大脑皮层表面在刺激电极近旁和在距离刺激电极6毫米左右两处记录直接刺激所引起的表面负电位,发现在各种药剂影响下两处的反应都呈平行的变化。以上一、二、三各项结果表明顶端树状突末端部分缺乏传导能力。从第四项结果,因为在离刺激电极较远处得到的反应是纯粹的突触后反应,而在远近两处得到的反应却具有相同的药理学上的特性,可以推断在刺激电极近旁的反应大概亦是纯粹的突...

The willow worm, Actias selene Hubner, belongs to the Saturinudae. The worms live outdoor on trees—most frequently on willows. However, they are perfectly fit to indoor conditions. On account of their strong vitality, the breeding of the worms presents almost no difficulty. Our preliminary breeding of the worms shows that under ordinary conditions and feeding with willow leaves they grow very well. In a better case it only takes 24 days from their larvas to cocoon. They breed three generations in one year, and their pupas survive in winter. Willow worms are heavier than ordinary domestic silkworms. A well-developed willow worm weighs over 10 grams and is 7-8 cm. in length. With a green colour, its body is scattered with tumors and full of hairs on their tips. The silk of willow worms presents a light-coffee colour and a shining lustre. As compared with that of domestic worms, it is somewhat thicker, while their tensile strength and elongation are nearly similar. Out of one cocoon a silk thread of about 350 meters in length may be obstained. It has the potentiality of being developed into a textile raw-material.

这篇报告是介绍一种野生蚕——柳蚕和柳蚕丝初步试验的情况。柳蚕在上海一带常见,许多地区也有分布。我们为了探求对它的利用,曾把它移放在室内饲养,发现生长良好,饲养方便。从蟻蚕到结茧,快的24天,就能结茧。一年中一般有三个世代,以蛹越冬。蚕身为绿色,体重比家蚕大,成熟的蚕儿有10克多重,身长达7~8公分。身上有瘤状突起,突起顶端长有刚毛。吐丝呈浅咖啡色,具有光泽,强力和延伸与家蚕丝相仿,但比家蚕丝略粗。柳蚕的特点是:生活力强;吃柳树叶(湿叶也无影响);虽系野生,但能在室内饲养;茧子又可以繅出成缕的丝达350公尺,是天然丝的一种资源。因此它可能具有重大的国民经济意义。

The study of blooming hahit of peanut is an impottant proeedure to make crosses between varieties either for genetic studies or lor breeding purposes. More than seventeen thousand peanut flowers were studied in the autumn at the college experiment Stat on of Fukien Provincial College of Agriculture, Yungan, Fukien,China.The results obtained from the study may be summarized in the following points: 1.The object of this experiment is to find out the blooming habit of Arachis hypogea. 2.The experiment was carried out under both field and grean house.The materials used for study were varieties widelv grown in Yungan; namely Valay(1), YuLin(a-1), Ping-siang. 3.The average time required from seeding to the blooming of the first flower is 38.36±5.11 days, It is a little longer under the green house(40.53± 4.28) than that in the field (36.2±4.06). 4.They are blooming absolutely in the day time.Peanut blooms from 6-7 o'clock.The maximum blooming period is at 6.00 A.M.(53.8%).The blooming period varies with green house and field. 5.The optimum blooming temperature is 22-24℃.(87.35%).No flower blooms below 17℃.and above 32℃. 6.In the field, peanut blooms beet at the relative humidity of 86%-100%, being 97.56% of total flowers studied.The best humidity is 95%-100%, being 78.34% of total flowers, 7.When the interaction of temperature and humidity is considered, the temperature of 22-24.9℃.with the relative humidity of 95%-100% is usually fitted.(82.89% of total flowers studied). 8.The time required from starting to bloom to not blooming varies with environments.It is usually shorter in the field than it is in the green house. 9.The number of flowers which bloom differs greatly with environment for individual plant. 10.The order of blooming starts from low to top of the plant. 11.The blooming days are rather scattering, being between 36-96 days after the blooming of the first flowers (88.91% of total flowers).In these 60 days there is no much difference in the numler of flowers that bloom.The maximum blooming date falls on the 59th day which is only 2.85% and the minimum date on the 63rd day is 0.85%.Besults show that there is no tendency for the flower blooming at any concentrated period.
