It is generally believed that tears are required to furnish only oxygen to the corneal epithelium. However, as tears are a very complicated solution, it is likely that other factors are essential to the cells of the corneal surface. The amount of light scattered from the epithelial surface of the excised rabbit cornea was examined with the in vitro specular microscope while the epithelium was b...

OBJECTIVE To compare the efficacy of lacrimal probing and syringing among 3% solution of Sodium Chloride and/or 0.2 mg/ ml Mitomycin-C as an adjunctive medication. DESIGN A prospective, randomized, 2 by 2 factorial design study. MATERIAL AND METHOD Forty-eight of nasolacrimal duct obstruction patients with epiphora symptom were randomly assigned to receive either Normal Saline Solution or 3...

Electrostatic interactions strongly affect the immersion depth of nanoparticles into an interface. We prove this statement by measuring the diffusion constant of charged nanoparticles at a sodium chloride solution/air interface. Interfacial diffusion of nanoparticles slows down with increasing ionic strength of the sodium chloride solution. Hydrodynamic calculations are used to estimate the imm...

Glycerinated rabbit psoas fibers 5-19 days old were immersed in contracting solutions with and without varying concentrations of different sodium salts. Raising the pH of the solution in small steps identified a threshold pH above which the fibers rapidly developed maximum tension. In solutions with added chloride or acetate (O-O.15 M), threshold pH and maximum tension changed only slightly. In...

the purpose of this research was to study the neutralization efficacy of a universal neutralizer proposed by the ctpa on a range of antimicrobial agents and its potential toxicity for microorganisms that are used for antimicrobial preservation testing. several types of antimicrobial agents including a mixture of methylisothiazolinone and its 5-chloro derivative, dimethylol dimethyl hydantoin, q...

Methods which can be used to assess the chloride permeability of various types of concrete in a relatively short time are described. An electrical potential from 60-80 volt DC is applied either between a chloride solution ponded on a slab surface and the top of rebar mat, or between two faces at a core taken from a structure. The amount of chloride and sum of the electrical current which passes...

XALATAN Sterile Ophthalmic Solution (latanoprost ophthalmic solution) is supplied as a sterile, isotonic, buffered aqueous solution of latanoprost with a pH of approximately 6.7 and an osmolality of approximately 267 mOsmol/kg.
