The detailed pathological lesions and the dynamic location of AEV in natural and experimental cases of chicken, chickling and embryos were reported. And AEV agar gel precipitin antigen and an inactivated oil-emulsion vaccine against AE were produced.

本项实验研究，旨在过去工作的基础上，利用分子生物学、分子免疫学的技术手段，探讨和揭示AE发生发展过程中的某些分子发病学机理的问题，并试图建立一种具有普遍指导意义的动物分子病理学研究的工作模型。

Under suitable infusion rate (30 mg/kg/hr), the physiological conditions remained stable for 5 hr, while the results suggested that the high dose and vehicle were not appropriate dosages for a stable anesthesia. Also, fMRI activations of the contralateral primary somatosensory cortex were readily observed under low dosage of α-chloralose infusion.

在低剂量的α－氯醛醣麻醉下，动物的生理状态可以维持稳定达5个小时，并且在fMRI的实验中得到清楚的BOLD反应，但是对照组以及高剂量的老鼠，在这样长时间的麻醉中，生理及麻醉状况无法维持稳定。

The results showed:(1)the factors which influence causal judgment were that the cause was the real cause or stimulative,the familiarity of the cause,and the covariation degree of causes with outcomes;(2)the character of questions didn't influence causal judgment;(3)causal judgment in some conditions were in accord with the probabilistic contrast model and the causal model theory,but they couldn't explain causal judgment in all conditions.

例如，在两个刺激同时出现并且之后伴随着一个结果事件出现的情况下，其中一个刺激对结果的作用可能被认为减弱了，另一个刺激被认为更易引起结果事件的产生[1]。多原因相互影响的现象，最初在动物条件反射中观察到，现在也已经在人类因果判断的实验中证实了[2]。研究因果判断中的多原因相互影响这一现象是有理论意义的，因为它证明了因果判断产生的情境重要性。

Objective: The purpose of our studies are gaining a better insight into the effect of genistein on mesangial cell"s phenotype change and ECM expression plus degradation under DN circumstances.We add genistein with different concentrations in high glucose cultured rat mesangial cells;feed DM rats with the single concentration genistein for different days;to explore the expression of SMemb,the mark of mesangial cell"s hypertrophy phenotype change;to examine the synthesis of Fn as well as the change of the balance between MMP-2 and TIMP-l;to comprehend its effect on renal pathological changes of DM rats and some related factors;trying toexplore the possible mechanisms.Through these studies,we will have some information about the experimental value of genistein in DN field.

目的：为了研究金雀异黄素对DN环境下大鼠MC肥大表型转换标志物SMemb和ECM分泌及降解的影响，我们拟在细胞水平以不同浓度的金雀异黄素作用于高糖培养下大鼠MC，在动物水平以同一浓度的金雀异黄素作用于DM大鼠不同时间，观察细胞表型转换标志物SMemb、ECM主要成分Fn、ECM降解酶系统基质金属蛋白酶—2(MMP-2)／基质金属蛋白酶抑制剂—1(TIMP-1)表达的变化，同时观察金雀异黄素对DM大鼠肾脏病理及影响肾脏病进展的糖脂代谢紊乱的影响，并进一步探讨金雀异黄素发挥作用的可能机制；为明确金雀异黄素在DN治疗中的地位及意义提供实验依据。

ACT is ready to try again with gaur and other endangered animals, Lanza says.

资助这项工程的位于马萨诸塞州Worcester的高级细胞技术公司的副总裁Robert Lanza说，若亚的死亡与克隆过程无关，高级细胞技术公司将继续用白肢野牛和其它的濒危动物作实验。

The present invention selects and uses hereditary hypertension rat and rat with normal blood pressure to make hybridization, and the rat whose blood pressure is normal and arterial pressure susceptivity reflection sensitivity is less than 0.3 ms/mm Hg can be screened out from filial generation, bred and propagated, and repeatedly bred and propagated, after above 12 generations so as to obtain the invented pure rat with stable hereditary property and spontaneous arterial pressure susceptivity reflection functional defect.

本发明涉及医学实验动物模型技术领域，是培育用于心血管疾病防治研究的一种自发性动脉压力感受性反射功能缺陷的纯种大鼠的方法。本发明选用遗传性高血压大鼠和正常血压大鼠杂交，从子代中筛选出血压正常、动脉压力感受性反射敏感性低于0.3ms/mmHg的大鼠培育繁殖，并反复按此标准在其下一代中筛选、繁殖，经12代以上便得到遗传性稳定的自发性动脉压力感受性反射功能缺陷纯种大鼠。

The SARS virus origin which obviously differs from the theory of out space origin and the theory of wildlife origin was theoretically discussed based on principles of pollution evolution ecology,pathogenesis and infectant characteristics of SARS,and some relevant experimental evidence. It emphasizes on the fact that increasingly combined pollution in China provides a substantial basis for virus evolution.

针对当前广为流传的SARS病毒"太空起源说"和"野生动物来源说"两种理论，本文根据污染进化生态学原理和SARS病毒发病传染特征，以有关实验结果为科学依据，阐述了SARS病毒的起源问题，指出：我国当前环境日益严重的复合污染为SARS致病病毒的产生提供了适宜的外部生态条件和物质基础，SARS致病病毒可能起源于多个病毒的基因重组或融合，更可能是一种来自于感冒病毒进化而形成的超级感冒病毒。

Methods: Study the newly found cell with the weak silver carbonate staining method of del Rio-Hortega. Using transmission electron microscopy, compare the newly found cell with the atypical cell found by Marc Lenoir and Philippe Vago, and extend young SD rat model to adult SD rat, young and adult Wistar rat,and extend drug of Neomycin to Amikacin to study the universality.
