Abstract
ABSTRACT
To treat uveitis and prolong the functional life of filtration surgery on glaucomatous eyes, some interleukin-1 (IL-1) blockers were used to inhibit IL-1-induced uveitis in rat eyes and to suppress proliferation of fibroblast-like corneal and conjunctival cells in the cell cultures, respectively. It was found in this research that the blood-aqueous barrier can be broken by IL-1α to allow fluorescein to enter the eyeballs and to be detected by fluorotron. The uveitis was effectively blocked by the IL-1 blockers studied in this research. It was also noted that the proliferation of fibroblast-like corneal and conjunctival cells was effectively inhibited by IL-1 blockers. The inhibition of cell growth seems to be caused primarily by the inhibition of RNA synthesis. There was a significant difference in the potency of IL-1 blockers to inhibit corneal vs. conjunctival cells. It was noted that conjunctival cells were more easily inhibited by IL-1 blockers than corneal cells. These results indicate that IL-1 blockers can suppress the proliferation of conjunctival cells at dose levels which do not affect the normal cell growth of corneal cells.
