The outer neuroblastic layer before it divided to inner and outer nuclear layer and outer complexiform layer and gonglion cell layer showed a temporal PCNA positive which was related to proliferation. The three cell layers had another PCNA positive when finished time changed from outer to inner after their morphologic development basically completed( outer nuclear layer:11～15 days,inner nuclear layer: 8～16 days, gonglion cell layer:16～21 days).

PCNA显示在外成神经细胞层分化为内、外核层和外丛状层之前，和节细胞各有一次和增殖相关的阳性表达。3个细胞层在形态学的分化基本完成后，又出现了一次结束时间是由外向内变化的阳性过程（外核层：第11天至15天：内核层：第8天至16天，神经节细胞层： 16天到21天，这一次阳性表达过程可见到细胞形态向成年形态的转化。

METHODS:Nestin expression was detected in 33 cases of neuroepithelial tumors using the immunocytochemical staining. The Nestin positive and negative cells were isolated by magnetic activated cell sorting. Nestin positive cells were culutered, identified, and induced to differentiate. The expression of Nestin protein was detected in Nestin+ cells by RTPCR.

采用免疫组化法检测神经上皮肿瘤组织中Nestin的表达情况，免疫磁珠法分选肿瘤组织中的Nestin+细胞，悬浮细胞培养法进行Nestin+细胞的增殖、分化与鉴定，RTPCR法检测Nestin蛋白在其中的活性表达情况。

We observed that the nestin positive cells distributed mainly near the internal limiting membrane and mantle layer of neuroepithelium. The positive cells arranged regularly along the neuroepithelial layer. After RA-treated, it was found that the number of neural stem cells reduced, especially at the eighth day of embryo p

RA作用后Nestin阳性细胞数目均普遍低于正常组；尤其在E8.5d时阳性细胞数目减少最为显著 p CDK5相似，于胚胎E14d已见其强阳性表达，成年期、老年期表

The results were compared among 4 groups. Results:①OCB positive rate was 37% in MS patients, which was lower than other reports, 24% in central nervous system infectious diseases group,5% in central nervous system non-infectious diseases group and 0 in peripheral nervous system diseases group,respectively.②OCB positive rate in conventional MS was 56%, which was higher than that in neuromyelitis optica.

结果①多发性硬化组OCB阳性率为37%，中枢神经系统感染组为24%，中枢神经系统非感染性疾病组为5%，外周神经系统疾病组为0；多发性硬化组的OCB阳性率比其他各组高，但低于国外报道的阳性率；②多发性硬化患者中传统型多发性硬化组OCB阳性率为56%，高于视神经脊髓炎组的11%。

The positive rate in nonbacterial prostatitis was 16.2%while it was negative in all the controls (P＜0.01). In 4 of the PCR positive cases, the urine and urethral scrapping cells were free from HSV-Ⅱ.

结果：前列腺液中HSV-Ⅱ阳性率为16.2%，对照组均为阴性(P＜0.01)。4例前列腺液HSV-Ⅱ阳性者，前列腺按摩前初始尿和尿道粘膜脱落细胞PCR检测均为阴性。

The results showed that ACP positive reactions were mainly deposited in lysosome, nucellar cell, cellular endomembrane, mitochondriurn, and endoplasmic reticulum in four tissues of the healthy shrimp. Furthermore, ACP activity was located in microvilli, and around partly lipid droplet in liver. AKP positive reactions were mainly deposited in cell membrane, nucellar cell, lysosome. endoplasmic reticulum and cellular endomembrane in four tissues.

结果显示，在健康的对虾体内，ACP依次出现在各组织中的溶酶体、细胞核、细胞内膜、线粒体、内质网以及肝脏组织中的部分脂滴周围及微绒毛中AKP依次出现在各组织中的细胞膜、细胞核、溶酶体、内质网以及肝脏组织中的脂滴周围及微绒毛中。

They include cerebellum,cerebral cortex,hypothalamus, mesencephalon, and pons.A few of positive cells could be seen in the medulla oblongata. NADPH-d positive neurons appears blue.Their shapes were diversform such as polygon,fusiform,nummular and oval etc. Karyon hasn't pigmentation. Dendriate and axon's pigmentation are clear.

实验一利用NADPH-d酶组织化学技术，对NOS阳性神经元在兔脑的总体分布规律及其衰老性变化进行了系统研究，结果表明：①NADPH-d阳性神经元分布于兔脑各个部位，几乎涉及所有区域：包括小脑、大脑皮质、丘脑下部、中脑、脑桥和小脑，而延髓分布较少。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。
