Mast cells in the lid and uvea of the rat, guinea pig, rabbit, and monkey were counted by averaging the counts in serial histologic sections and multiplying by an appropriate calculated geometric factor. The lid counts are higher than the uveal counts and the iris count is low compared with the remainder of the uvea. Histamine and serotonin contents xoere determined by biochemical assay. The uv...
The circulating renin-angiotensin system (RAS) is an important determinant in maintaining adequate systemic blood pressure, and it also may modify organ-specific blood flow. All recognized RAS components have been identified in the eye. In this study, angiotensinogen (ANG) was localized using an affinity-purified antibody and paraffin sections of seven human eyes. An antibody for human serum al...
Sympathetic ophthalmia is a rare bilateral granulomatous inflammation that follows accidental or surgical insult to the uvea of one eye. Onset of sympathetic ophthalmia can be insidious or acute, with recurrent periods of exacerbation. Clinical presentation shows mutton-fat keratic precipitates, choroidal infiltrations, and Dalen-Fuchs nodules. Histopathology reveals diffuse or nodular granulom...
PURPOSE These experiments were undertaken to assess the role of increased nitric oxide production in the pathogenesis of vascular dysfunction associated with endotoxin-induced uveitis. METHODS Lipopolysaccharides (LPS) (100 micrograms of Salmonella minnesota) was injected into foot-pads of Lewis rats randomly assigned to an untreated group or to a group treated with subcutaneous injections of...
