Which may be useful in the study of insulin signaling transduction pathway in the brain.methods:use immunohistochemical techniques to investigate the neuronal distribution of insr、irs-1 and irs-2 proteins in rat brain with polyclonal insr、irs-1 and irs-2 antiserum.results:insr、irs-1 and irs-2 are widely distributed in the brain of normal adult rat ,especially in the cerebral cortex 、hippocampus and numerous hypothalamic nuclei including the arcuate nucleus、ventromedial nucleus and paraventricular nucleus which are crucial for the control of food intake.conclusion:insr、irs-1 and irs-2 are widely distributed in the brain of normal adult rat, suggesting that they may play an important role in the normal function of central nervous system.

应用免疫组织化学染色的方法观察正常成年大鼠脑中insr、irs-1、irs-2的分布。结果：insr、irs-1、irs-2在正常成年大鼠脑中广泛分布，在与学习记忆和能量代谢相关的脑区如大脑皮质、海马、丘脑和下丘脑的部分核团均有表达。结论：insr及irs-1、irs-2在正常成年大鼠脑中广泛表达，但表达部位不完全一致，提示它们在大鼠中枢神经系统的正常功能活动中可能发挥不同的作用。

Octoploid tritielytrigia type TAI-7045 showed immunity to yellow rust and middle resistance powdery mildew. CH-9916 is immune to yellow rust in seedling and adult stages, powdery mildew in seedling and adult stages, and their powdery mildew middle resistance. These suggested that the high powdery mildew-resistance in Octoploid tritielytrigia TAI-7045 had probably been transferred into common wheat.

通过对条锈病及白粉病抗性评价，结果表明：亲本八倍体小偃麦TAI-7045、小偃麦衍生系CH-9916对条锈病表现免疫，对白粉病表现中抗，而另一亲本"晋麦33"对条锈病、白粉病表现高感，推测小偃麦衍生系CH-9916抗条锈病及白粉病的基因均来源于代换的一对染色体——亲本八倍体小偃麦TAI-7045即来源于中间偃麦草。

Morphology and Ultrastructure of Compound Eyes in the larval stages of Cherax quadricarinatus Morphology and Ultrastructure of Compound Eyes was investigated by TEM and SEM in the larval stages of Cherax quadricarinatus. The result is indicated: Morphology of compound eye and ommatidium in the larval stage were similar to that in adult stage. The area of the ommatidia increases from 906±29. 6μm〓 in larva Ⅰ(1. 5cm long) to 967±53. 3um〓 in larva Ⅲ(3cm long) and 3724±230.3μm〓 in adult (16cm long).

扫描电镜结果表明：刚离开母体的仔虾（体长约1cm）复眼和小眼的形态已接近成体，小眼的平均表面积由1.5cm仔虾的906±29.6um〓增长为3cm仔虾的967±53.3um〓和16cm成体的3724±230.3um〓；小眼个数也从体长1.5cm仔虾的1001个增加到3cm仔虾的1238个和16cm成体的5652个，红螯螯虾复眼的增大是由于小眼面积的增加和小眼数目的增多而引起的。

Methods The larva and adult rat flea were reared with artificial diet and white mouse respectively.The process of larva pupation and adult emergence were recorded,and the sex ratio was calculated during the flea development.

用人工饲料和小白鼠分别喂饲印鼠客蚤的幼虫和成蚤，在饲养过程中记录幼虫的化蛹和羽化过程，并鉴别羽化成蚤的性别。

Using GSA-〓 lectin histochemistry, the first appearance of microglia occurred at E13, usually stained as scattered amoeboid cells. From then on, the number of microglia increased steadily, reached a peak at postnatal day 7 (P7), and then reduced gradually to adult level. Generally the morphological form of microglia undergoes transformation from early rounded or ameboid to adult resting ramified as they differentiate during development.

使用凝集素GSA-〓亲和组织化学染色，本实验最早观察到小胶质细胞在胚胎13天（E13），为散在分布的圆形或阿米巴样细胞，随后细胞数量逐渐增多；总体而言小胶质细胞的形态遵循着由圆形或阿米巴样逐渐转向纤细分枝状的演变规律，不同阶段细胞形态各有其特点，在不同区域也存在差异；小胶质细胞的数量在生后第七天（P7）达到高峰，其后开始逐步降低直至成年。

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。
