Positive influence of hyaluronate on cell vitality of human conjunctival cells after alkali injuries.

Background: To analyse the influence of hyaluronate (HA) on the cell vitality of human conjunctival cells after chemical injuries from NaOH or alkali-containing household cleaners.

Methods: Human conjunctival cells (Chang cells) were incubated either with NaOH solutions or dilutions of household cleaners. HA (0.

Iodide protection from UVB irradiation-induced degradation of hyaluronate and against UVB-damage of human conjunctival fibroblasts.

Background: To determine whether iodide protects from UVB irradiation-induced destruction of hyaluronate and against UVB injury of cultured human conjunctival fibroblasts.

Methods: Hyaluronate and primary cultured human conjunctival fibroblasts were incubated with various concentrations of iodide and then exposed to UV light irradiation of 312 nm. Hyaluronate destruction was determined by viscosity measurements.
