epulis is a benign neoplasms of the oral cavity, derived from the periodontal ligament or connective tissue, occur commonly in dogs and rare in cats. however, it is very rare in horse. the tumor can be very large to interfere with normal mastication. several forms of epulides can histologically be distinguished in dogs. fibromatous epulis microscopically characterized by a dense well vasculariz...

in the present study, we describe a subcutaneous mass between the left flank and hip in a 2-year-old male great dane dog. histopathologically, cells appeared to be spindle shaped around a central capillary together with a fingerprint pattern. immunohistochemical analysis presented that the neoplastic cells expressed vimentin, but did not stain for s-100 protein. on the basis of histopathology a...

Pathogenesis of silicosis is still being evaluated. Cellular and histopathological changes in lung following acute and chronic exposure of quartz in rats have been investigated. Inbred wistar rats were given single intratracheal injection of quartz (10 mg in 0.05 ml saline) in groups of acute model, and inhalation of quartz (40 mg/m3 with air flow 5 l/hr in a simulation chamber, 6 hr/day) in gr...

Acute experimental allergic encephalomyelitis, an animal model of CNS inflammatory and demyelinating disease, was produced in guinea pigs and imaged with MR. Correlation of histopathology with MR revealed acute mononuclear perivascular inflammatory changes and edema corresponding to the high-intensity abnormalities observed on long repetition time (TR) images. Our results suggest that in acute ...

Until recently, sheep-associated malignant catarrhal fever (SA-MCF) was diagnosed mainly on the basis of clinical presentation and histopathological changes. Using clinically diagnosed field cases, we have evaluated a seminested PCR and a competitive inhibition enzyme-linked immunosorbent assay (CI-ELISA) and compared these assays in the diagnosis of SA-MCF in cattle with histopathology as a pr...

oxidative stress is one of the important causes of the type 1 diabetes induced changes in the sperm quality. bioflavonoids, rutin 10 mg/kg and naringin 10 mg/kg were evaluated for their protective effects on sperm parameters, oxidative stress, and histopathology of type 1 diabetic rats. results demonstrated the reduction in sperm count, sperm motility and vitality in diabetic rats. mass drug ad...

Anterior segment fluorescein angiography in scleral disease reveals highly characteristic changes in the vasculature of the anterior segment associated with necrotising scleritis. The vaso-obliterative changes discovered in this investigation have been correlated with the histopathology in a patient who had to have tissue replaced. Light and electron microscopy of scleral tissue excised from si...
