A re-evaluation of the skin test of herpes simplex virus

Cell-mediated immunity to herpes virus type-1 in patients with recurrent corneal herpes simplex

The proportion of T lymphocytes in the peripheral blood, their phytohaemagglutinin reactivity, and the leucocyte migration inhibitory effect of purified tuberculin protein were found to be equal in 25 recurrent corneal herpes simplex patients and 17 healthy individuals who had never suffered from clinically manifest herpes simplex virus (HSV) infection. Conversely, the HSV vaccine inhibited the leucocyte migration in the healthy group, but not in the recurrent herpes patients when the clinical symptoms were manifest. In 14 recurrent corneal herpes simplex patients, the examinations were repeated after a 3-month symptom-free period, and in these periods the patients corresponded equally to the healthy group in every respect.

The essentials of data sources in eye epidemiology

The extensive literature on eye epidemiology was selectively reviewed to provide a concise and comprehensive summary on the current status of available data sources. The topics being covered were epidemiologic data evaluation, data handling, card registration, computer analysis, geographic factors, socio-economic conditions, personal attributes, genetic backgrounds, twin analysis and laboratory procedures for host defense factors including humoral and cellular immunity. Also, the scope of this article encompassed such major practical issues as glaucoma, cataract and other blinding diseases as well as traffic and occupational hazards. Epidemiologic information thus obtainable through data searching may prove tobe instrumental in the identification of any potential preventive measures in ophthalmology and public health.
