Single doses of all-trans-N-retinylacetamide slow down the ERG amplitude recovery after bleaching in rats.

To assess the safety and to quantify the effects of a single application of all-trans-N-retinylacetamide on the rat retina measured by electroretinography (ERG). Brown Norway rats were assigned to either a control group (n = 13) or to one of the three groups treated with a single intra-peritoneal dose of all-trans-N-retinylacetamide: 20 (n = 8), 5 (n = 7), or 1 mg/kg (n = 8). Full-field ERGs were performed 7 days before (baseline) and 12 h after treatment.

In vivo toxicity study of rhodamine 6G in the rat retina.

Purpose: To investigate the intraocular effect of rhodamine 6G (R6G) on retinal structures and function in an in vivo rat model and to develop an in vivo method for accurate evaluation of new dyes for intraocular surgery.

Methods: R6G in physiologic saline solution (PSS) was injected into the vitreous of adult Brown Norway rats at concentrations of 0.0002%, 0.

Hepatitis C is an immense health and epidemiological problem; its effective prevention by vaccination, however, is still impossible. The available methods of treatment, e.g.

[Prevalence and risk factors of dry eye syndrome].

The aim of the study was to estimate the frequency of dry eye syndrome and to analyze the risk factors of this disease. We examined a group of 140 patients aged 24-93, suffering from dry eye syndrome. The patients were treated in the Ophthalmology Clinic in Lublin in 1999-2001.

[Residual clubfoot correction by means of lateral cuboid resection].

The paper presents the late results (after 5-16 years; mean follow-up--9.5 years) of lateral cuboid resection performed in 55 children with pathologic foot adduction. The age of the children ranged from 18 months to 12 years (average age 41 months).
