Morphological and Histochemical Changes in the Regenerating Vomeronasal Epithelium.

Histochemical changes in lens epithelium of rabbits after x-irradiation.

Acid phosphatase and ubiquinone reactions have a different distribution in the lens epithelium of the normal rabbit. Acid phosphatase is more concentrated in the germinative area than the central area, and ubiquinone is quite evenly distributed in the entire lens epithelium. Exposure to a cataracto genie dose of x-ray causes a greater decrease in the acid phosphatase in the germinative zone tha...

Morphological, histochemical and immunohistochemical study of the gill epithelium in the abyssal teleost fish Coelorhynchus coelorhynchus.

Histochemical and immunohistochemical study was carried out on nitrinergic innervation and neuroendocrine system in the gill epithelium of the abyssal fish Coelorhynchus coelorhynchus. The results showed that nNOS-positive nerve fibers, originating from the branchial arch were present in the subepithelial tissue of branchial primary filament. nNOS-positive neuroendocrine cells were also present...

Morphological changes in injured retinal pigment epithelium and photoreceptor cells after transplantation of stem cells into subretinal space

Introduction: Degenerative retinal diseases are main cause of irreversible blindness. Stem cells therapy is a promising way in these diseases. Therefore, mesenchymal stem cells because of its safety can produce degenerated cells and can play important role in treatment. The aim of this study was to examine morphological changes in injured retinal pigment epithelium (RPE) and photoreceptor cells...

Surface glycoproteins in the regenerating corneal epithelium of Triturus cristatus.

Functional competence of regenerating ocular surface epithelium.

Several aspects of the ocular surface epithelium, including its clinical appearance, its effect on the strength of underlying stromal wounds, and its healing rates, have been compared between regenerating epithelium of conjunctival and that of corneal origin in rabbits. The results showed that conjunctival epithelium could not transform completely into functionally competent corneal epithelium ...
