Abstract
• New Zealand albino rabbits received daily intraperitoneal injections of alcohol (ethyl alcohol), 1.6 g/kg and the effect of short-term (three days) and long-term (six weeks) administration on corneal inflammation was studied. Both regimens produced an average peak serum concentration of more than 0.200 g /dL, a level consistent with gross intoxication in the majority of humans. Clinical signs of intoxication were present in all animals, manifested by a gross disturbance of equilibrium and gait. Neither regimen produced measurable liver damage. Nonetheless, following both regimens of alcohol administration, significantly fewer polymorphonuclear leukocytes invaded the corneas of animals receiving alcohol than invaded the corneas of simultaneously run controls receiving intraperitoneal saline. These data provide a mechanism to explain why an alcoholic individual might not cope with a corneal infection as well as a nonalcoholic person, an observation long thought to be true clinically.
