Using in vivo intracellular recording technique, we studied the binocularity of the dorsal lateral geniculate nucleus neurons in the monocular eyelid sutured cats. We found that almost all the neurons responded to the flashing spots to the nondominant eyes, and there was no significant difference of the response properties between the neurons in the deprived and non-deprived layers.

采用在位胞内记录技术,研究了单眼视觉剥夺猫外膝体神经元的双眼反应特性,结果发现单眼剥夺猫外膝体几乎所有的双眼反应神经元都对非优势眼的闪烁光斑刺激有不同程度的反应,并且剥夺层和非剥夺层神经元在反应特性上没有明显差异。

Obducta to nine kinds of larch volatile compositions, namely R-α-pinene, S-α-pinene,β-pinene, ocimene, phellandrene, 3-carene, myrcene, camphene and phytol with EAG and Y-tube olfactometer. The results showed that 0.4 molL^(-1), most volatile compositions had significant EAG responses compared with the blank control (P.05), with exception of females to R-α-pinene, males to R-α-pinene and phellandrene.

结果表明:在0.4molL^(-1)浓度下,雌蛾除了对R-α-蒎烯、雄蛾除了对R-α-蒎烯和水芹烯没有明显EAG反应外,对其余挥发物的EAG反应与对照相比差异均达到显著水平(P.05),并且雌、雄虫之间的EAG反应也存在一定的差异。

The results were as follows:(1) Reaction-time is a distinguishable item;(2)Reaction-time of seamen is longer than seafaring students;(3)Reaction-time are different of age group;(4)Reaction-time got one or two difference of seaman s work age,sailing age,headship,education,source and marriage.

结果表明:①反应时是一项鉴别力很高的项目;②海员的反应比航海专业学员的反应时长;③不同年龄海员组的反应时存在差异;④海员的其它个人特征如工龄、海龄、职务、学历、来源和婚否的不同对反应时的影响只表现在其中的个别方面或没有影响。

Our synthesis is characteristic of ready availability of starting material (piperonal, ethyl oxalate, allyl bromide, ethyl 4-bromobutyrate), operationally simple reactions with cheap reagent chemicals, and atom economy.

In this study,intracellular recordings were performed and 34 neurons in MGC of Agrotis segetum were recorded;all those neurons responded to sex pheromone.12 neurons just tested by sex pheromone,and 22 neurons both tested by sex pheromone and electrical stimulation.

两种刺激方式均能诱导出兴奋反应,电刺激得到的兴奋反应比由性信息素刺激引起的要短;MGC神经元对两种刺激的超极化反应幅度影响没有显著性差别,在电刺激实验的2 2个神经元上,超极化反应幅度和抑制时间都与神经元本身放电频率有一定的相关性。

The presence of solvent disfavors the reaction, whereas the participation of water in the aminolysis reaction plays a positive role and reduces the activation energy greatly.

亚氨基二乙腈在没有外加催化剂的近邻界水中可以顺利发生水解。实验测定了亚氨基二乙腈在近临界水中(压力10MPa,温度200~260℃,反应时间10~60min)的水解反应动力学数据并考察了时间、温度、压力和初始反应物/水比对反应物转化率和产物产率的影响。

Here we report a 22year-old man who suffered from recurrent fever accompanied by chest and abdominal pain for more than 10 years. The attack frequency was about once per 23 weeks. Although he consulted many clinics and even received appendectomy at the age of 15, no definite diagnosis was given. During the admission, many laboratory examinations failed to show any abnormality except mild leukocytosis and elevated C-reaction protein. Image studies including chest X ray and abdominal CT scan showed negative result but, interestingly, Gallium-67 scan showed a hot spot in right lower chest and right lower abdomen. After prophylaxis with colchicines 1.0 mg per day, he has enjoyed more than 2 years without the above symptoms.

本篇报告发表一位22岁的男性,十余年来每隔二三周即发生周期性的发烧,浆膜炎;虽然他遍访数家医院,并且在十五岁时被诊断为阑尾炎,并接受开刀治疗,还是没有得到正确的诊断与治疗,此次住院当中,除了稍微的白血球与C-反应蛋白偏高以外,很多实验室检查皆正常,影像学检查包括胸部X光,腹部电脑断层均正常,但有趣的是Gallium-67扫描发现在右胸及右下腹出现强烈反应,经诊断为地中海热后给予秋水仙素预防性治疗,病人已经超过二年没有复发。
