چکیده

Dynamic changes of rat corneal epithelium and stroma after alkali burning were observed with the electron microscope. The neovascularization process in the stroma was almost the same as that observed after burning by heat. Reversible changes of the epithelial cells occurred throughout the course of wound healing. Approximately 10 days after burning, cells in deeper layers of the epithelium showed temporary changes such as increased in number of mitochondria and formation of lamellar cytoplasmic infoldings. These changes

Prevention of stromal ulceration in the alkali-burned rabbit cornea by glued-on contact lens. Evidence for the role of polymorphonuclear leukocytes in collagen degradation.

Stromal ulceration of the alkali-burned rabbit cornea was found to be associated invariably with phagocytically active polymorphonuclear leukocytes (PMNs). A glued-on methylmethacrylate lens applied to corneas soon after burning, however, prevented re-epithelialization and also prevented PMN infiltration of the stroma and stromal ulceration. Subsequent partial detachment or complete removal of ...

A neutrophil chemoattractant is released from cellular and extracellular components of the alkali-degraded cornea and blood.

PURPOSE A tripeptide chemoattractant(s) for neutrophils has been shown to release from alkali-degraded cornea. This study is designed to determine the source of the chemoattractant(s). METHODS Whole corneas were degraded in 1 N NaOH for 10 minutes, 30 minutes, 1 hour, 4, 8, 24, and 48 hours to determine an optimal duration of alkali exposure for production of the chemoattractant. Whole cornea...

Effect of leukocytes on corneal cellular proliferation and wound healing.

PURPOSE To establish whether fucoidin, by blocking the adhesion of leukocytes on the limbal vascular endothelium, prevents extravasation of the cells from the blood stream into the limbal stroma and the wounded area after corneal injury. Successful leukocyte blocking enabled investigation of the influence of leukocytes on corneal cellular proliferation after corneal wounding. METHODS Thirty-t...

An inhibitor of the matrix metalloproteinase synthesized by rabbit corneal epithelium.

Normal and abnormal processes of cellular invasion often are initiated by degradation of basement membranes. The process of corneal ulceration might operate via similar mechanisms; degradation of the corneal stroma is not seen until after the basement membrane underlying the corneal epithelium in the preulcerative lesion is lost. Recent data implicate a member of the matrix metalloproteinase (M...
