Objective To study the expression of tumor necrosis factor-α, intercellular adhesion molecule-1(ICAM-1) and S-100 in the process of pigmentary degeneration, and its significance.

目的 观察视网膜色素变性过程中，视网膜外节层内组织细胞肿瘤坏死因子α、神经组织蛋白S-100、细胞间黏附分子－1(ICAM-1)的表达情况，探讨其在视网膜色素变性过程中的作用及意义。

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。

Objective To report 1 case with cardial malignant fibrohistiocytoma, and discuss its clinical pathological features based on literature review.

目的 报告1例罕见的心脏恶性纤维组织细胞瘤，结合文献复习，讨论心脏恶性纤维组织细胞瘤的临床病理特点。

The antibodies to cathepsin D and glial fibrillary acid protein and immunohistochemical PAP technique were used to observe the changes in microglia and astrocytes in the cerebella from NPC and normal mice of different ages.

应用组织蛋白酶D和胶质原纤维酸性蛋白抗体以及免疫组织化学方法，观察生后不同年龄的NPC和正常小鼠小脑内小胶质细胞和星形胶质细胞的变化。

Methods Rat spinal cord injury models were established by aneurysm clip compression, and nestin expression and proliferation of ependymal cells at different times were shown with pathological and immuno-histochemical staining.

应用动脉瘤夹压迫建立大鼠脊髓损伤模型，通过组织病理学及免疫组织化学方法检测不同时段室管膜细胞的反应性增生和神经外胚层多潜能细胞特异性抗原nestin的表达。

In order to distinguish the type of GFP positive cells in glomeruli further, we also carried out fluorescence histochemistry double staining, the results of it were: the GFP positive cells in recipients glomeruli in mice of the four, five, six groups were blood cells in glomeruli capillary loop, but not the glomeruli resident cells, for example, endothelial cells, epithelial cells or intercapillary cells.

为了进一步鉴别受体鼠肾小球内GFP阳性细胞的种类，我们进行了免疫荧光组织化学双染色，结果显示：④、⑤、⑥组受体鼠肾小球内的GFP阳性细胞可能是肾小球毛细血管袢内的血细胞而非肾小球的固有细胞，即内皮细胞、上皮细胞或系膜细胞。

Objective To observe the characteristic of apoptosis in the largeintestinal carcinomas and adenomas and assess the significance of apoptosis in it.

目的 观察大肠癌和腺瘤组织细胞凋亡的特征，探讨细胞凋亡和增殖在大肠癌和腺瘤组织中的意义。

Semi-thin sectioning and the method c.ommonly referred in histochemistry were used to study the development of vascular bundles in Aloe arborescens leaves with emphasis on the origins and tissue types of vascular bundle sheath cells and aloin-containing cells.

采用半薄切片和组织化学方法研究了木立芦荟叶内维管束的发育过程，并着重于维管束鞘细胞和芦荟素细胞的来源及组织类型。

Methods Fifteen healthy, female SD rats were employed in the experiment. Sensitized systematically with keyhole limpet hemocyanin, the animals were inoculated with the same antigen through cochlea basal turn into the labyrinth. Adminstrated 5-bromo-2′-deoxyuridine intraperitoneally, the rats were sacrificed and the temporal bones were harvested at 3, 7,14 day after labyrinth vaccination respectively. The frozen sections of the decalcified samples were dealt with H-E staining and immunohistohemical methods to investigate the cellular infiltration, BrdUrd and IgG positive cells in the ES.

选用SD大鼠15只，以钥孔虫戚血蓝蛋白（keyhole limpet hemocyanin，KLH）全身免疫后，经耳蜗底回钻孔以相同抗原进行内耳免疫，然后分别在内耳免疫后3、7和14 d腹腔注射溴脱氧尿嘧啶核苷（bromodeoxyuridine，BrdUrd）后处死动物，取颞骨经组织学处理制作冰冻切片，用免疫组织化学技术观察内淋巴囊的细胞浸润、增殖和IgG细胞的分布状况。

The results showed that the number of TILs was varied greatly from case to case in untreated NPCs, the infiltrating lymphocytes within carcinoma was mainly T cell, no B cell.

结果表明，各种淋巴类细胞在癌组织中的分布差异很大，在组织中浸润的细胞主要是T淋巴细胞。
