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.

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。

Results After 4 hours of test, the non-epidemic strains became positive and the average growth density of the non-epidemic strains was higher than that of the epidemic strains; however, some were still lower than the epidemic strains. In contrast, at the eighth hour oftest, when epidemic strains got positive, they showed higher average growth density.

结果 在甘露醇发酵实验第4小时非流行株出现阳性反应时，非流行株整体生长趋势较流行株迅速，但单个菌株生长速度有快有慢；第8小时流行株出现阳性反应时，其生长高于非流行株。

Some patients have ''monomicrobial bacterascites'' in which cultures are positive but there is normal ascitic neutrophil count.138 Such infections are thought to occur relatively commonly, and the majority are eradicated by the body's natural defence mechanisms (for example, opsonic and complement mediated bactericidal activity).138 139 When a positive culture is obtained, a further ascitic tap with a neutrophil count should be obtained.

有些患者有着&单一微生物细菌性腹水&，其腹水培养为阳性但腹水白细胞计数正常。138这些感染被认为较为常见，大部分可被机体天然的防御机制（如调理素和补体介导的杀菌活性）所根除。138，139当腹水培养为阳性时，应进一步进行腹穿并行嗜中性粒细胞计数。

Results Osseous metastasis was found in 22 cases out of the 107 cases with the positive rate of 20.6%: osseous metastasis occurred in 4 cases with no osteodynia, single metastasis in 9 cases and multi-metastasis in 13 cases; the location of osseous metastasis ranged as follows: 61 metastasis in thoracic cage, 41 in pelvis, 39 in vertebral column, 8 in four limbs and 4 in skull; along with the prolongation of the follow-up, the positive rate of osseous metastasis increased.

结果 107例中发现骨转移22例，阳性率20.6%。其中无骨痛患者发生骨转移4例，单发转移9例，多发转移13例。发现骨转移灶的部位依次为胸廓(61处)、骨盆(41处)、脊柱(39处)、四肢(8处)及头颅(4处)。随乳腺癌术后回访年限的增加，骨转移阳性率增加。

The results showed that the 56kD and 26kD antigens had better immunogenicity and could not react with the sheep positive serum of Mycoplasma pneumonia and negative serum of E. ovis. Of the 64 samples detected, the positive rate was 66.7%(42/64), 22.9% higher than that of direct microscopic examinerion.
