The results show that the compound conductive fiber has typical structure of sheath-core consists of black greened polyaniline electric conductive deposition as the skin and the white polypropylene matrix fiber as the core, which makes the compound fiber preferable physical mechanical property. The intensity and the elongation ratio of the electric conductive fiber are decreased but the thermal stability is enhanced after modified. The compound fiber has the good acid resistance but poor base resistance. The thermal stability of the compound fiber prepared by 4-methyl-benzene sulfonic acid is better than that prepared by hydrochloride acid. Moreover, the compound fiber can be re-doped by other organic or inorganic acid after freed from the adsorbed acid. Furthermore, the electric conductivity of the compound fiber decreases with the temperature increasing but hardly changed with the humidity. The adsorptive ability and therefore the content of the polyaniline, the constant of electric conduction, and the durability of the compound fiber can be enhanced by thinning the diameter, section heteromorphosis, section heteromorphosis and plasma treatment of the surface or blending with COPET of the fiber.

Antibodies against col Ⅲ reacted strongly in the entire pterygial stroma. Conclusions Components of ECM are changed in the pterygium: the sub-epithelial connective tissues and vessels are more prominent in the pterygia than in normal conjunctiva tissues, and abnormal fibers are visible only in the deeper subepithelial connective tissues. This study documents the overexpression of LN and col Ⅲ. They may play roles in cellular adherency, migration and angiogenesis. Also this study documents the overexpression of MMP3 which may degrade ECM in the pathogenesis of the pterygium.

Special staining methods, such as Masson and the Van Gieson staining were used to study the distribution of collogen fibers and elastic fibers. ResultsBy HE staining, the subepithelial connective tissues and vessels in the pterygium were more prominent than normal conjunctival tissues. An amorphous subepithelial superficial hyalinized zone and coarse eosinophilic granular materials were observed in the pterygia, but they were not found in normal conjunctival specimens. Coarse fibers were visible only in the deeper subepithelial connective tissues of pterygial samples. With Masson′s staining, the dense staining of collagen fibers was also more prominent in the pterygium than in the subepithelial connective tissues of normal conjunctiva. Abnormal collagen fibers were visible in the deeper sub-epithelial connective tissues of pterygial samples. With Van Gieson staining, abnormal collagen fibers were visible in the deeper subepithelial connective tissues. Dark coarse elastic fibers were found in the abnormal fibers only in the subepithelial deep connective tissues of pinguecula in the pterygia but not in the conjunctiva. With immunohistochemistry staining, MMP-3 was strong in the pterygial epithelium, moderate in fibroblast and absent from pterygial vascular walls. LN was strongly expressed in the blood vessel wall, moderately in the epithelial basement membrane and absent from the entire stroma.

RESULTS: During 10 - 12 weeks, in cuntrol group: The defect area was repaired by white and soft tissue that had no resistance to press. The repaired tissue was still lower than the surrounding articular surface with clear boundary. By histological observation, it was found that the defect was repaired by the mechanism similar to inflammatory reaction and the defect is ultimately filled by the hyperplasia of hyaline degenerative fibrous tissues. In filling group: the defect was repaired by semi-transparent, smooth, textured tissues with polish that had resistance to press as well as elasticity. The repaired tissue was almost similar to the shape of the surrounding cartilage,difficult to be distinguished. After histological observation, it was found that there was no inflammatory reaction, but active hyperplasia of inner bonetissue and cartilage tissues; a lot of osteoid tissues and trabeculation were found. Newlborn cartilage was fused with surrounding cartilage tissue and connected with surrounding tissues.

Some cell dropped into the cavity and became free. Thrombosis or part organization could be seen. The internal elastic layer became thin, disappear or broken. In internal and middle layer existed fibroblasts, fibrocytes and collagen. Some of the wall indicated hyaline change, soomth muscle cell decreased greatly. The massive inflammatory cells invaded the middle and external layer. There were many foam cells in the capsule tissue. Cytoplasm was filled with fatty tissue and cholesterol. some cavities were full of thrombosis. Some thrombosis was fibrosis, the bottom was organization.

Marston, MD, from the University of North Carolina School of Medicine in Chapel Hill, and colleagues."Dermagraft is a bioengineered dermal substitute that laboratory data suggest has two principal modes of action. It provides living, human dermal fibroblasts that deposit matrix proteins and facilitate angiogenesis. It also provides a preformed collagen matrix, receptors, and bound growth factors that facilitate the migration of the patients' epithelial cells that close the wound."
Marston医师及同事表示,针对治疗慢性溃疡的生理失能的患者,还需要更多有效的疗法,而人工皮肤就是一种生物工程皮肤代用品,这一项实验室数据显示两种最重要的功能模式,它提供活体人类皮肤纤维组织母细胞,储存母体蛋白质并促进血管新生,另外它也提供预先形成的胶原母体、接受器及束缚成长因子,帮助病患的上皮细胞移动,使伤口愈合。
