The rates of corneal penetration and efflux of phenylephrine (PE) and its metabolites were found to be limited by the epithelium. The rate constant for corneal penetration as measured in a lucite block perfusion system was 1.06 X 10~ hr" when the epithelium was present and 1.25 X 1O~ hr" when the epithelium was denuded. Epithelial removal reduced the half-time (t)/2) for corneal efflux of PE fr...

Objective: The beneficial effects of clove on toothache have been well documented. We have also previously shown the analgesic effects of clove essential oil. The present work was done to investigate the analgesic effects of the aqueous extract of clove using hot plate test. The possible role of opioid receptors in the analgesic effects of clove was also investigated using naloxone. Materials a...

PURPOSE To evaluate changes of levels of erythropoietin (EPO) and VEGF in aqueous humor before and after an intravitreal injection of bevacizumab (IVB) and determine the underlying correlation between them. METHODS This prospective study involved 21 eyes of 21 patients with surgery-required advanced neovascular glaucoma (NVG) and 20 control subjects from October 2011 through November 2012. Th...

A hydrogel was prepared by crosslinking aqueous solutions of sulfonated polyacrylamide/chromium triacetate for use in water shut off operations. Gel swelling and the effects of salinity, injection time and flow rate on residual resistance factor (Frr) were investigated. In the presence of electrolytes, gel swelling decreased by about 80%. Results showed that oil permeability increased as inject...

A primary immunogenic uveitis was produced in rabbits by the intravitreal injection of bovine plasma albumin or ovalbumin. A secondary or recurrent uveitis was induced by intravenous injection of the specific soluble antigen several months after the cessation of primary inflammation. Aqueous antigen-antibody complexes were studied at times of maximal clinical response in both primary and recurr...

Analysis of the electrostatics of charge carrier injection into molecular crystals during nonequilibrium electron transfer reactions demonstrates the unique advantage of aqueous or similar electrodes in measuring limiting currents which yield the rate constant of the injection process. At the phase boundary molecular crystal/aqueous electrolyte image forces are negligible due to the slow orient...

The purpose of this study was to evaluate the effects of extracts of Coptidis rhizoma, Phellodendri cortex and Gardeniae fructus, which are medicinal herbs in Orengedoku-to (Huanglin-Jie-Du-Tang in Chinese), and crocetin (a major component of Gardeniae fructus) on experimental elevation of aqueous flare in pigmented rabbits. To produce aqueous flare elevation, 0.5 microg/kg lipopolysaccharide (...

We report a case of posterior scleritis effectively managed with intravitreal bevacizumab. A 71-year-old woman was diagnosed with posterior scleritis. Although she was initially treated with systemic steroids, her clinical presentation deteriorated. She was then treated with a single intravitreal injection of bevacizumab and aqueous humor collection. The aqueous level of vascular endothelial gr...

Central retinal vein occlusion (CRVO) is frequent in patients with systemic lupus erythematosus (SLE), but the treatment of the macular edema with this disease is extremely difficult. We report a case of cystoid macular edema (CME) secondary to unilateral CRVO in a patient with SLE that responded to intravitreous injection of an anti-vascular endothelial growth factor (VEGF) agent. A 33-year-ol...
