Acellular allogeneic dermal matrix is the dermal replacement of heterogenous human skin in which the cellular elements have been removed by special technique and basement membrane complex have been remained. It becomes a kind of 3D porous acellular dermal scaffold. It supports fibroblast infiltration, neovascularization and epithelialization in the absence of an inflammatory response.

异体脱细胞真皮基质（acellular allogeneic dermal matrix， ADM）来源于正常的异体皮肤组织，经过特殊的理化处理去除真皮中的细胞成分，保留原有的胶原三维结构和完整的基底膜，成为一种多孔的三维膜性支架，其空间网状结构有利于细胞的增殖、毛细血管增生，加速组织的愈合过程，移植后可以迅速被血管化和自体细胞重建。

RESULTS: The collapse was obvious at weeks 2 and 6 after modeling, with only few granulation tissues and fibrous tissues. No chondrocytes were observed. At weeks 12 and 18, fibrous tissues were found at the defect site, and bone tissue and cartilage proliferation was observed at the bottom and margin. However, it was greatly different from normal cartilage. Moreover, there was still no chondrocytes.

The results showed with the increasing of NaCl concentration, the phenomenon of carnification could be found in the leaves of Arabidopsis thaliana . Under the stress of NaCl lower than 100 mmol/L, the tissue structure of root had no distinct difference from the control. When the concentration of NaCl was higher than 250 mmol/L, the stained color of safranine was deep but not even, and color in fibrovascular tissue and peripheral cortex cell were deeper than that around fibrovascular tissue.

To sum up, we first conclude that we can isolate mesenchymal stem cells from human fetal articular cartilage and they can be induced to differentiae into several cells under appropriate induction conditions. Anymore, they have their original tissue speciality. Therefore, we first report that mesenchymal stem cells of articular cartilage origin are superior to mesenchymal stem cells of bone marrow origin as seeding cells of cartilage tissue engineering and we provide a kind of new seeding cells of cartilage tissue engineering for the future clinic application.

综上所述，我们首次报道不仅可从人胚胎的关节软骨中获得间充质干细胞，而且软骨来源的间充质干细胞除具有骨髓来源的间充质干细胞的多向分化能力外，还具有其来源的软骨组织特异性，那么，其作为软骨组织工程的种子细胞要优于骨髓来源的间充质干细胞，从而首次提出了一种新型的软骨组织工程的种子细胞，对于未来的软骨组织工程的临床应用提供理论依据。

Downgrowth of the epidermis is serious, in the case of HA neither clear inflammatory cells infiltration nor marked downgrowth of the epidermis was observed in every observation stage. The material bind tightly with skin tissue. The histocompatibility of HA for percutaneous device is fine.

结果表明：钛合金材料周围组织局部慢性炎性细胞浸润，轻度充血和水肿，有严重的表皮向下生长；HA材料周围组织未明显炎性细胞浸润，各观察期均无显著的表皮向下生长，材料与皮肤组织结合紧密，组织相容性良好。

Met hod: Hypertrophy of prostate model rat was established by injecting t estosterone to gelding male rats. After being treated with Qianlie Huichun ig 30 days, the rats were killed and prostate glands were resected for examination. The Fas expressio n was examined by immunobistochemical SABC.

采用大鼠去势后注射丙酸睾酮引起前列腺增生法造模，灌胃给药 30d后，处死大鼠取前列腺组织并称湿重，用免疫组化方法检测前列腺组织中Fas阳性细胞的表达率，用流式细胞术检测细胞凋亡率和观察细胞凋亡峰。

By suspending cell culture from the callus of P. thugbergii and by fluorescent observation, a new method, which is easy and sensitive to observe cell activity and to test the phytotoxicity of various bacteria, was used. This method can be utilized to study the bacterial toxins. Cultured filtrates of some strains of the nematode-carrying bacteria were bioassayed for their toxicity to suspending cultured cells from P. thugbergii callus. Strong toxic effects were observed by the filtrates of Pseudomonas spp., P. fluorescence, and Sphingomonas spp., these bacteria species are coincide with those in the early stage of pine wilt disease.

本试验使用了黑松愈伤组织的细胞悬浮培养方法，用荧光方法观察各种细菌对植物细胞的毒性测定，这种方法具对细胞的活性观察容易、灵敏度高等特点，证明可用于细菌的毒素研究；对松材线虫携带的细菌的部分菌株，用其培养滤液对黑松愈伤组织的悬浮培养细胞的生物测定初步证明，松材线虫携带的细菌中以假单胞菌、荧光假单胞菌和少动鞘氨醇单胞菌的滤液对黑松细胞具有较强的毒性，这与松树发病早期出现的细菌种类相一致。

Methods The rat thoracic duct endothelia were cultured and the morphology observed and identified by TEM and Factor Ⅷ-related antigen immunohistochemically.
