Pigmented epithelial tumours of the conjunctiva.
Two out of 60 conjunctival epithelial tumours reviewed between 1973 and 1989 were found to be pigmented. One tumour was a pigmented papilloma and the other a pigmented squamous cell carcinoma. The melanin pigment was found in epithelial tumour cells as well as in macrophages, dendritic melanocytes, and Langerhans cells. The distinction between the latter two types of cells was possible in one o...
متن کاملNucleoside transport mechanisms in the pigmented rabbit conjunctiva.
PURPOSE To elucidate the mechanisms of nucleoside transport in the pigmented rabbit conjunctiva using [3H]uridine as the substrate. METHODS Excised pigmented rabbit conjunctiva was mounted in a modified Ussing chamber for measurement of short-circuit current (Isc) and [3H]uridine transport. RESULTS [3H]Uridine transport in the mucosal-to-serosal direction at 10 microM exhibited directionali...
متن کاملCarrier-mediated transport of monocarboxylate drugs in the pigmented rabbit conjunctiva.
PURPOSE To determine whether an Na+-dependent monocarboxylate transport process exists on the mucosal side of the pigmented rabbit conjunctiva and to evaluate how it may contribute to the absorption of ophthalmic monocarboxylate drugs. METHODS L-lactate was used as a model substrate. The excised pigmented rabbit conjunctiva was mounted in a modified Ussing chamber for the measurement of short...
متن کامل[De novo growth of a capillary hemangioma of the conjunctiva].
CLINICAL CASE A 22-year-old woman patient, diagnosed with an inclusion cyst of the conjunctiva in the nasal sector of the left eye, who after 2 shot/needle injections in the lesion came to our clinic with a dense subconjunctival hemorrhage in four quadrants and with severe pain. After excision biopsy, a capillary hemangioma of the conjunctiva was diagnosed. DISCUSSION Conjunctival capillary h...
متن کاملGrowth factor expression in ophthalmic pterygia and normal conjunctiva.
The expression of growth factors in ophthalmic pterygium and phenotypically normal conjunctiva was examined and correlated with the clinical findings. Fifteen specimens of ophthalmic pterygia and 8 specimens of phenotypically normal conjunctiva were examined. Total RNA was extracted from all specimens and mRNA levels for transforming growth factor (TGFB1), vascular endothelial growth factor (VE...
