OBJECTIVE To evaluate the effect of blocking the angiotensin II AT-1 receptor by the systemic administration of candesartan on the expression of intercellular adhesion molecule-1 in the sclera and choroid of hypercholesterolemic rabbits. METHODS New Zealand rabbits were divided into 3 groups, as follows: GI, which was fed a rabbit standard diet; GII, which was fed a hypercholesterolemic diet;...

OBJECTIVE To analyze the expression and cellular distribution of intercellular adhesion molecule 1, E-selectin (endothelial leukocyte adhesion molecule), vascular cell adhesion molecule 1, very late antigen 4, and lymphocyte function associated antigen 1 (LFA-1) in diseased and normal human sclera. METHODS Monoclonal antibodies to vascular cell adhesion molecule 1, very late antigen 4, interc...

The Fadenoperation was performed on 24 rabbit eyes. In 8 eyes the globe and muscle were removed intact and in 16 eyes the muscle was dissected from the sclera to determine the site and degree of attachment. The greatest degree of adherence was found between the muscle and the sclera at the site of the suture, less attachment at the lateral and medial border of the muscle, less in the central ar...

We demonstrate the capability of the optical coherence tomography (OCT) technique for depth-resolved monitoring and quantifying of glucose diffusion in fibrous tissues (sclera). The depth-resolved and average permeability coefficients of glucose were calculated. We found that the glucose diffusion rate is not uniform throughout the tissue and is increased from approximately 2.39+/-0.73 x 10(-6)...

Dermatan sulfate proteoglycans were isolated from adult bovine sclera and adult bovine articular cartilage. Their immunological relationships were studied by enzyme-linked immunosorbent assays using polyclonal antibodies raised against the large and small dermatan sulfate proteoglycans from sclera and a polyclonal and monoclonal antibody directed against the small dermatan sulfate proteoglycans...

PURPOSE Although visual deprivation causes increased ocular elongation and myopia in both birds and mammals, changes in sclera appear to be in opposite directions. Because avian sclera has a cartilaginous layer as well as the fibrous layer found in mammals, we examined whether the scleral responses to various visual manipulations differ between the two layers. METHODS To produce increases in ...

PURPOSE To compare two sclera decontamination methods: treatment with glycerin versus treatment with gamma irradiation, alkali and glycerin, aiming to detect the clinical and histological alterations in rabbit anophthalmic sockets reconstructed with sclera-involved polymethylmethacrylate spheres. METHODS Thirty-nine New Zealand-breed rabbits were divided into two groups: group I, whose animal...
