PURPOSE To investigate the in vivo expression of toll-like receptor 4 (TLR4) and its associated lipopolysaccharide (LPS) receptor complex in the human eye. METHODS Normal human ocular tissues were evaluated for in vivo TLR4, MD-2, and CD14 mRNA and protein expression by RT-PCR and immunohistochemistry, respectively. The distribution patterns and phenotypes of the cells expressing these protei...
Derivatives of IS!-substituted phenothiazine are concentrated in the tissues of the uveal tract of pigmented animals. The concentration levels for phenothiazine in the uveal tissue may reach 50 times the mean distribution value even 48 hours after a single dose of 5 mg. per kilogram. All other tissues have lower concentration levels than the mean distribution value. Only samples involved in exc...
One hundred and twenty-seven eyes from 66 Mycobacterium leprae inoculated armadillos were studied histologically and some ultrastructurally. Inflammatory reactions were found in the following extraocular tissues: the eyelid, including the orbicularis muscle and the third eyelid, extraocular muscles, tear gland and Harder's gland. The early and slight changes of the intraocular tissues, small am...
The inflammatory process of the uvea is called uveitis and may cause sight threatening damage to the eye. The aetiological factor in about 30% of the cases of uveitis is unknown. If established clinical entities without known cause, such as Fuchs' uveitis, are included, no aetiological agent or association with systemic disease can be identified in about 50% of cases.' Uveitis may be induced by...
AIMS To define a retinoinvasive phenotype of uveal melanoma based on an informative case and survey of literature. METHODS A 65-year-old woman developed a circumscribed mixed cell type melanoma of the ciliary body that was locally excised. After 6 years, secondary glaucoma evolved. Three years later a ring melanoma was diagnosed and the eye was enucleated. The histopathological material was a...
Case Report A 24-year-old white woman was first seen in consultation in September, 1960, complaining of a "little vein" in the nasal side of the sclera of the right eye, which had been growing over a period of three months without symptoms, but three days previously she complained of sudden pain and "severe loss of vision". Examination.-Right eye: A salmon-pink solid mass was seen growing insid...
Fish names are not only of interest to the ichthyologist. Linguists too have been studying fish name as they are generally regarded as a more stable subsection of the lexicon, which is less subject to change and more reliable as a source for historical reconstruction. However in the Pacific, especially in Polynesia with its history of migration, linguists have to be careful when using fish name...
Sera from patients with proved and suspected melanoma of the uvea and from patients with innocuous uveal naevi were found by immunohistological techniques to have an affinity for the cytoplasm of malignant choroidal melanoma cells in an appreciable proportion of cases. The responsible antibodies were subsequently shown to react with smooth muscle protein in a variety of tissues and not to be me...
2 cases of diffuse malignant ring melanoma of the anterior uvea are presented. A correct clinical diagnosis led to enucleation in case 1, while in case 2, the eye was enucleated 2 years after anti-glaucomatous surgery.
