PURPOSE To evaluate DNA damage markers and the antioxidant status of serum and aqueous humor in glaucoma patients. METHODS Aqueous humor and serum samples were obtained at the time of surgery from 28 patients with glaucoma and 27 patients with cataracts. Total antioxidant status (TAS) and 8-hydroxy-2´-deoxyguanosine (8-OHdG) levels of all samples were determined by spectrophotometric and enzy...
Leptospiral organisms have long been presumed to be associated with the presence of equine recurrent uveitis. This project was undertaken to determine the presence of Leptospira spp. in the aqueous humor of horses with uveitis to determine if there was an association with inflammation. Thirty horses were determined to have recurrent uveitis based on clinical evaluation or history. Sixteen horse...
Serum and aqueous humour zinc and copper concentrations of 44 patients with glaucoma and cataract were determined. Serum values were found within normal ranges. The highest mean copper concentration was seen in the glaucoma group. In addition there was a significant negative correlation between the aqueous humour levels of zinc and copper in patients with glaucoma. It was concluded that an incr...
Imidazole, given intraperitoneally to rabbits, inhibited the prostaglandin E1-induced (PGE1) elevation of intraocular pressure. The maximum imidaz-le effect occurred at three to six hours after intraperitoneal infection. The prostaglandin E1-induced aqueous humor protein elevation was reduced markedly in the imidazole-pretreated rabbits. Intravenous administration of imidazole also was effectiv...
Background: Glaucoma is a progressive optic neuropathy and is one of the leading causes of blindness worldwide. Different factors have been contributed in the pathogenesis of glaucoma including H. pylori infection. Objective: To determine the levels of anti-H. pylori IgG antibody in the aqueous humor of patients with pseudoexfoliation and primary open angle glaucoma, in comparison with age and ...
The aqueous humor is a colorless, transparent fluid that fills the anterior chamber of the eye. It plays an important role in maintaining the intraocular pressure and providing nourishment to the lens and cornea. The constitution of the aqueous humor is controlled by the blood-aqueous barrier. Though this ocular fluid has been extensively studied, its role in ocular physiology is still not comp...
PURPOSE The ectodomain of CD44, the principal receptor for hyaluronic acid (HA), is shed as a 32-kDa fragment-soluble CD44 (sCD44)-which is cytotoxic to trabecular meshwork (TM) cells and retinal ganglion cells (RGCs) in culture. The purpose of this study was to characterize sCD44 further by determining the phosphorylation of aqueous humor sCD44 in normal and primary open-angle glaucoma (POAG)....
PURPOSE To investigate the migration of cultured bovine trabecular meshwork cells to aqueous humor and some of its constituents, and to compare the migration of normally proliferating and growth-arrested cells. METHODS Cellular migration was evaluated in 48-well microchemoattraction chambers, and the chemoattractants used were bovine aqueous humor, glycoproteins, and growth factors. RESULTS...
