查询词典 coarse mesh

With the increasing of undercooling, the mean crystal diameter of supercooled solidification microstructures shows a variation from coarse to fine, then fine to coarse, and finally fine again. The coarse crystals are developed crystals, while the fine crystals are spherical crystals with a mean diameter about 50μm.

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.
