[Detection of myeloperoxidase in eye tissues of man]

Myeloperoxidase (MPO) is an enzyme which usually detected in leukocytes of peripheral blood. Its principal function is to produce bactericidal hypochlorite-ions in reaction of hydrogen peroxide with chlor ions. The present work deals with testing myeloperoxidase activity in different eye tissues. Evolution of MPO activity has been tested by means of dianisidine reaction and immunochemical identification in extracts. High activity of MPO was found for retina and lens of healthy men and elderly people with lens opalescence. It should be noted that cellular body, cornea, aqueous humor, vitreous humor do not manifest any noticeable activity. Iris has low activity.
