Aim: To explore mechanisms of erythrocyte in brain edema development after traumatic intracerebral hemorrhage by studying effect of erythrocyte on brain water content and expression of TNF-α in rats with TICH.

目的：观察创伤性脑内出血模型中红细胞对脑含水量和TNF-α表达的影响，探讨红细胞在TICH后脑水肿形成中的作用机制。

They expressed prominently in the forebrain, mid-hindbrain boundary, branchial arches, somites, limb bud and tailbud of mouse embryos. These expression profiles indicate that Fgf8, Spry2 and Sef belong to a synexpression group and suggest that these genes may functionally interact during embryonic development.

在小鼠8.75天胚胎上（E8.75），这些基因在前脑，中脑和后脑的交界处，鳃弓，体节及尾芽等处有明显的表达，这些表达的相似性提示了它们可能在胚胎早期发育过程中的相互作用。

At 24 h, Ang1 was expressed mainly in the lens, optic cup, mesencephalon, ventral part of hindbrain, and myotomes in the somites, while zfTie2 was mainly expressed in intersomitic vessels including dorsal aorta and axial veins, and sprouting vessels from the dorsal aorta in the trunk. VEGF was expressed mainly in the lens, optic cup, mesencephalon and myotomes in the somites, while zfFlk1 was mainly expressed in intersomitic vessels including dorsal aorta and axial veins, and sprouting vessels from the dorsal aorta in the trunk.

结果从受精卵胚胎发育第12小时可见血管内皮细胞生长因子和血管发生素1及其相应受体flk1和Tie2的表达；在受精卵胚胎发育的第16小时，血管内皮细胞生长因子和血管发生素1主要在头部和尾部胚芽表达；第24小时在眼球、视窝、中脑、后脑的腹前侧和肌节中表达，Tie2和Flk1主要在肌间背部动脉血管、躯干新生血管芽和轴向静脉中表达。

Objective: To observe the changes of the activity of catecholamine neuron groups in the brain stem after acute soman intoxication.

目的：观察梭曼急性中毒后脑干儿茶酚胺神经元的活动变化。

Methods Medullary slices of newborn Sprague-Dawley rats were prepared for the experiment. The electrophysiological experiment comprised 5 groups (each with 8 slices), each of which were perfused with artificial cerebrospinal fluid, CO, 1H-[1, 2, 4] oxadiazolo [4, 3-a] quinoxalin-1-one (a specific inhibitor of sGC, ODQ group), ODQ+CO (ODQ+CO group), and dimethyl sulfoxide, respectively. The burst frequency of hypoglossal rootlets was recorded as an index of rhythmic respiratory activity. Radioimmunoassay was employed to determine cGMP levels of the medullary slices of the ACSF control group, exogenous CO group, ODQ group and ODQ+CO group (n=6/group).

电生理实验分为5组（每组n=8：单纯人工脑脊液对照组、外源性CO组、ODQ组、ODQ+CO组和二甲基亚砜组，制备SD大鼠离体延髓脑片标本，以舌下神经根节律性自发放电频率(bust frequency， BF)为指标，分别灌流以上药物，观察呼吸节律的变化，并以放射免疫方法检测单纯ACSF对照组、外源性CO组、ODQ组和ODQ+CO组给药后脑片cGMP水平的改变（每组n=6）。

Aromatase protein and its mRNA were abundant in the forebrain, midbrain, spinal cord, wheel organ and Hatschek's pit, but not abundant in the hindbrain or early ovary and testis. No aromatase expression was detected in both irregularshaped cells and ciliated mucous cells in the Hatschek's pit or in the mature ovary and testis. Aromatase immunoreactive material was distributed in the cytoplasm with negative nuclei.

芳香化酶蛋白和转录物在前脑、中脑、脊髓、轮器和哈氏窝十分丰富，而后脑、早期卵巢和精巢不够丰富；没有芳香化酶表达的部位是哈氏窝另两种细胞(不规则形细胞和带纤毛粘液细胞)以及成熟卵巢和精巢；芳香化酶免疫活性物质分布在胞质，核为阴性。

Results: After six-week intrathecal injection, cerebrospinal fluid recovered to normal, symptoms and signs of patients were improved obviously.

结果：鞘内给药6周后脑脊液基本恢复正常，患者症状与体征均显著好转。
