purpose: to compare the efficacy of treatment with fortified cefazolin-gentamicin versus fortified vancomycin-ceftazidime eye drops for treatment of bacterial corneal ulcers. methods: a double-blind clinical trial was performed on 89 patients with bacterial corneal ulcers who were referred to feiz hospital, isfahan, iran from 2004 to 2005. patients were randomly assigned to two groups: one grou...

tears have antimicrobial, nourishing, mechanical, and optical properties and contain components such as growth factors, fibronectin and vitamins to support proliferation, migration and differentiation of corneal and conjunctival epithelial cells. lack of these epitheliotrophic factors, as in dry eye, can result in severe ocular surface disorders such as persistent epithelial defects. recently, ...

The purpose of the studies was to choose additives for eye drops containing cefazolin and the assessment of the influence of used additives and the storage temperature on the physicochemical properties and the stability of the eye drops. The drops were 1% sterile solutions of cefazolin in citrate buffer of pH 6.15-6.20. The drops were preserved with 0.002% thiomersal or 0.001% phenylmercuric bo...

The aim of the studies was to determine with HPLC method the stability of ceftazidime in buffered 1% and 5% eye drops of proposed formulary composition, which were stored for 30 days at the temperature of 4 degrees C and 20 degrees C and protected from light. The 1% and 5% eye drops were prepared under aseptic conditions by dissolving Biotum (ceftazidimum), dry injection formulation, in citrate...

Abstract— In this paper, we propose a gateway algorithm supporting both weighted fairness and queue management. Though some algorithms are proposed for fairness with queue management in the literature, they do not concern about the flow weight. Our proposed algorithm classifies an incoming packet into a flow and drops it stochastically according to the queue length and the fair bandwidth share ...

Triple Graph Grammars (TGGs) are a rule-based technique with a formal background for specifying bidirectional model transformation. In practical scenarios, the unidirectional rules needed for the forward and backward transformations are automatically derived from the TGG rules in the specification, and the overall transformation process is governed by a control algorithm. Current implementation...
