The Polysaccharide of the Vitreous Humor
Since the work of Miirner (1) the existence of a mucoid in the vitreous humor has seemed well established. All subsequent workers used his method of preparation: the precipitation of the diluted native vitreous humor with dilute acetic acid. In his recent book on the nature of the vitreous body (2), Duke-Elder gives its concentration as 0.021 per cent, or about 30 per cent of the total protein ...
متن کاملAnaphylatoxin levels in human vitreous humor.
The complement system is involved not only in host defense against infection but also in autoimmune tissue damage. Using a radioimmunoassay, we sought to measure levels of C3a, C4a and C5a (activated complement fragments with anaphylatoxin functions) in human vitreous humor from eyes with and without vitreal inflammation. Vitreous from 11 patients with clinical evidence of vitritis (Group 2) ha...
متن کاملThe penetration of gentamicin into the vitreous humor in man.

There were no detectable gentamicin levels in the vitreous humor of patients who received the drug systemically. Of the patients who received gentamicin subconjunctivally, three quarters had no detectable gentamicin levels, only three of these patients had therapeutic conc...
متن کاملDiabetes-induced oxidative stress in the vitreous humor
PURPOSE Diabetes is accompanied by fundamental rearrangements in redox homeostasis. Hyperglycemia triggers the production of reactive oxygen and nitrogen species which contributes to tissue damage in various target organs. Proliferative diabetic retinopathy (PDR) is a common manifestation of diabetic complications but information on the possible role of reactive intermediates in this condition ...
متن کاملProteins of the vitreous humor during experimentally induced myopia.
Significant myopia was evident within 14 days after a translucent goggle was placed over the eye of a newly hatched chick. This myopia was characterized by large negative refractive error, increased axial and equatorial eye lengths, and increased wet eye weight. The volume of the vitreous humor increased in the myopic eye, because of a signficant accumulation of liquid vitreous humor. The prote...
