An entertainment-education radio soap opera introduced in Tanzania in 1993 was evaluated by means of a field experimental design in which the radio program was broadcast by seven mainland stations of Radio Tanzania. An eighth station broadcast alternative programming from 1993 to 1995, its listenership serving as a comparison area in which contemporaneous(More)
We conducted a retrospective analysis of 600 patients with uveitis seen at the Estelle Doheny Eye Center to determine the frequency of occurrence of the various forms of uveitis and to see if the causes of uveitis have changed as compared with previous studies. In 402 cases (67.0%) we established a specific diagnosis based on history, physical findings, and(More)
In many regions of Asia and Africa, consanguineous marriages currently account for approximately 20 to 50% of all unions, and preliminary observations indicate that migrants from these areas continue to contract marriages with close relatives when resident in North America and Western Europe. Consanguinity is associated with increased gross fertility, due(More)
PURPOSE To present revised criteria for the diagnosis of Vogt-Koyanagi-Harada disease, a chronic, bilateral, granulomatous ocular and multisystem inflammatory condition of unknown cause. METHODS Diagnostic criteria and nomenclature were subjects of discussion at the First International Workshop on Vogt-Koyanagi-Harada Disease on October 19-21, 1999, at(More)
The feasibility of using fluorescein-conjugated lectins to visualize and differentiate three fungi commonly involved in ophthalmic mycoses was evaluated. Using a panel of fluorescein-conjugated lectins, Candida albicans, Aspergillus fumigatus, and Fusarium solani were rapidly and reproducibly visualized in in vitro culture isolates, as well as in tissue(More)
One hundred four cases of sebaceous carcinoma that arose from ocular adnexa, with at least five years' follow-up information following diagnosis, were studied to extend the authors' previous observations on various prognostic factors in these tumors. Twenty-three patients died from metastatic disease. Although sebaceous carcinomas elsewhere in the skin are(More)
In this study enzyme glutathione peroxidase was localized in ocular tissue of Lewis rats using the peroxidase antiperoxidase immunohistochemical technique. Antisera to glutathione peroxidase was raised in a rabbit. Immunoreactive glutathione peroxidase was found to be distributed predominantly in the corneal epithelium and endothelium, choroid, inner(More)
Localization of catalase in rat and bovine ocular tissues was investigated by an immunohistochemical method. Antisera to purified catalase was raised in a rabbit. Purity of catalase was determined by gel electrophoresis and specificity of the antibody was tested by immunoblot. The immunohistochemical method revealed the presence of catalase predominantly in(More)
Serine hydroxymethyltransferase (SHMT), a pyridoxal-5' -phosphate (PLP) dependent enzyme catalyzes the interconversion of L-Ser and Gly using tetrahydrofolate as a substrate. The gene encoding for SHMT was amplified by PCR from genomic DNA of Bacillus stearothermophilus and the PCR product was cloned and overexpressed in Escherichia coli. The purified(More)
In acute inflammation, the tissue damage is generally mediated through polymorphonuclear leukocytes and macrophages. Recent studies on the mechanism of this leukocyte-mediated cytolysis have demonstrated that these cells, on stimulation, release a variety of reactive products. These metabolic products consist of superoxide and hydrogen peroxide, which in(More)
