Objective:To investigate the effects of marrow stroma cells on the expression of nerve growth factor and brain-derived neurotrophic factor after traumatic rat brain injury.

目的：研究骨髓基质细胞治疗脑创伤大鼠后内源性的神经生长因子和脑源性神经营养因子的影响。

Stuss and Shammi's most humorless patients had a damaged area in the frontal lobe known as the medial ventral prefrontal cortex.

斯特斯和谢米所研究的那些最没有幽默感的病人，其脑前叶的受伤位置就在一个叫做"脑前叶下腹中轴皮层"的地方。

In order to probe into the development feature of telencephalon of Onychodactylus fischeri, and enrich the research data of comparable neurobiology, preliminary studies of telencephalon of adult and subadult Onychodactylus fischeris have been made by using HE-staining method to describe the characters of their histological structures.

为了探讨爪鲵端脑的发育特点，充实比较神经生物学的研究资料，本文采用常规 HE 染色法，初步研究了成体和亚成体爪鲵端脑的组织学结构特征。

IL-1βmRNA expression in the developmental brain in Wistar rat: IL-1β mRNA in hippocampus, cerebral cortex and subcortex was detected by postnatal day 1 and gradually increased with development, reached a peak at postnatal day 21, and then gradually decreased to lower level at adult; In P77PMC rat, IL-1β mRNA expression was similar to Wistar rat before postnatal day 14, then gradually increased and surpassed Wistar rat at postnatal day 28, reached a peak in adult.

原位杂交显示谷氨酸诱导Wistar大鼠惊厥和P77PMC大鼠听源性惊厥后脑内IL-1βmRNA表达情况。结果发现，两种不同惊厥模型大鼠惊厥后脑内IL-1βmRNA表达存在明显的差异。谷氨酸引起惊厥诱导脑内皮层、海马和丘脑IL-1βmRNA表达增高的程度远较P77PMC大鼠听源性惊厥为低，而且惊厥后IL-1βmRNA表达增加较慢，于4-8h达高峰，而听源性惊厥可于惊厥后2h迅速达高峰。但两种形式惊厥诱导脑内IL-1βmRNA表达最高的部位均是海马。

Intracellular pH change did not influence the actions of ketamine while superfusion of NMDA .

在pH 6.81的人工脑脊液中，ketamine抑制放电频率增快的药效减弱了35 %，在pH 8.1的人工脑脊液中，ketamine抑制去极化的药效减少了29 %，而胞内酸化或碱化则不影响ketamine拮抗NMDA的药效。

The process of cerebral hypoxia was simulated by giving superfusion with ACSFOGD for 14 minutes in the control and test groups. The propofol test group was subdivided into P1, P5 and P15 groups to undergo superinfusion with ACSF containing 1, 5 and 15μmolL^(-1) propofol respectively.

缺氧组：脑片用缺氧无糖的人工脑脊液灌流14min，实施缺氧过程；药物组分为P1、P5和P15组：在ACSFOGD灌流液中分别含1，5和15μmolL^(-1)的丙泊酚。

Objective To investigate from theoretical and clinical aspects the symptoms of ＂ damage of brain collateral by toxin＂ and a tentative research thinking of symptomatology based on the present related studies.

目的 在"毒损脑络"现有研究的基础上，从理论和临床角度初步探讨"毒损脑络"的症状表现，并探讨其症状学研究的初步思路。

Results:(1) cerebrovascular syphilis 1 case,tabes dorsalis 2 cases;(2) Inall cases,Serum and cerebrospinal fluid syphilis antibody reaction showed positive; CSF protein content was increased significantly,and cells increased (3) MRA and DS...

结果(1)脑血管梅毒1例，脊髓痨2例；(2)3例血和脑脊液的梅毒抗体均为阳性；脑脊液蛋白含量增加、细胞数增多；(3)脑血管梅毒患者MRA及DSA显示左大脑中动脉M1段闭塞；左大脑前动脉及左大脑后动脉通过皮层支向左大脑中动脉供血区代偿供血；(4)2例脊髓痨患者头颅及胸髓MRI无特殊发现，肌电图及周围神经活检不支持周围神经受损。

Results:(1) cerebrovascular syphilis 1 case, tabes dorsalis 2 cases;(2) mall cases. Serum and cercbrospinal fluid syphilis antibody reaction showed positive; CSF protein content was increased significantly, and cells in creased (3) MRA and DSA of cerebroascular syphilis show that Mi segment of the left middle cerebral artery is blocked. The left posterior cerebral artery and the left anterior cerebral artery compensate blood supply for the left middle cerebral artery through the conical branch.(4) MRI of head and thoracic cord was normal in 2 cases of tabes dorsalia. Result of EMG and biopsy of suml nerve not manifest damage of peripheral nerveous system.

结果：(1)脑血管梅毒1例，脊髓痨2例；(2)3例血和脑脊液的梅毒抗体均为阳性；脑脊液蛋白含量增加、细胞数增多：(3)脑血管梅毒患者MRA及DSA显示左大脑中动脉M1段闭塞；左大脑前动脉及左大脑后动脉通过皮层支向左大脑中动脉供血区代偿供血；(4)2例脊髓痨患者头颅及胸髓MRI无特殊发现，肌电图及周围神经活检不支待周围神经受损。
