The effect of xanthines on various microorganisms was studied. The antibacterial effect was not high; most of the test organisms could easily withstand a concentration of 2,500 mug/ml. Caffeine was more antibacterial than theophylline, and the latter more than theobromine. Caffeine citrate exhibited greater inhibitory effect than did pure caffeine. The(More)
A 73-year-old woman underwent corneal transplantation because of lattice dystrophy. Histopathologic examination of the excised host cornea disclosed eosinophilic deposits that stained positively with Congo red and showed green birefringence with polarized light. Immunofluorescent examination showed protein AA and protein AP in the stromal deposits. To the(More)
Currently, the armamentarium of contact lenses that can be used for therapeutic effect provides a wider selection of lenses than ever before. If the therapeutic goal is protection and healing of the corneal epithelium, epithelial or stromal edema is best avoided, and the selection of a high-Dk silicone hydrogel (balafilcon A, lotrafilcon A) lens or a very(More)
Therapeutic soft contact lenses were first approved in the 1970s, but the variety of available materials and parameters continues to evolve. Currently, the armamentarium of therapeutic contact lenses allows the clinician to select lenses that not only protect the corneal surface but also assist in modulation of the healing process.

Collagen synthesis was studied in monolayer cultures of rabbit corneal endothelial cells by following [14C]proline and [3H]glucosamine or [3H]fucose incorporation into a fraction enriched for collagen and its precursor molecules. Sodium dodecyl sulfate gel electrophoresis of this fraction showed that it consisted of a high-molecular-weight (greater than(More)
Rotavirus is the most common cause of moderate-to-severe infant diarrhoea in developing countries, resulting in enormous morbidity, mortality, and economic burden. A bovine-human reassortant pentavalent rotavirus vaccine (BRV-PV) targeting the globally most common strains was developed in India and tested in a randomized, double-blind, placebo-controlled(More)
