coccidiosis and gizzard erosion are rare conditions in cage bird. a male zebra finch was presented with a history of watery diarrhea, anorexia, ruffled feathers, weight loss, and lethargy and died finally. gross necropsy revealed small areas of erosions and hemorrhages on the gizzard wall. the intestine was oedematous. the spleen appeared pale and small. the testes were asymmetric.histologicall...

BACKGROUND The aim of this study was to investigate the effects of intramuscular IL-8 injection on hepatic tissues using an in vivo histopathological animal model. MATERIAL AND METHODS Twelve New Zealand white rabbits were used for this randomized, controlled, single-blinded interventional study. For 6 days, 1 gluteus maximus muscle was injected daily with 1 mcg/kg of IL-8 in 6 rabbits (Group...

Hypertensive rat arteries exhibited severe medial smooth muscle cell injury and necrosis. Electron microscopic observations showed the smooth muscle cells of these arteries exhibited characteristics of focal cytoplasmic necrosis forming new cytodemarcating membrane between the healthy cytoplasm and necrotic cytoplasm. When the focal necrotic cytoplasm disappeared from the injured smooth muscle ...

objective: morphological changes of ca1 neurons in rat hippocampus after transient and permanent focal cerebral ischemia were studied to clarify the nature of postischemic cell death in the subfield. materials and methods: male adult rats were divided into 3 groups: control (shamoperated), transient ischemic group (30 minutes of mcao followed by 48 hours of reperfusion), and permanent ischemic ...

herpes simplex virus accounts for 10 to 25% of sporadic viral encephalitis throughout the world among people of different age with two peaks, one at 5 to 30 and the other at > 50 years of age. pathologic process includes focal brain tissue inflammation and necrosis (predominantly temporal lobe). therefore local neurological signs and symptoms will ensue. although csf pressure rising due to infl...

A review is made of the various histological lesions observed in hepatitis B virus-related liver diseases, including different forms of acute and chronic hepatitis, cirrhosis, and hepatocellular carcinoma. The elementary lesions discussed include acidophil necrosis (apoptosis), confluent lytic necrosis in its different patterns, piecemeal necrosis, focal necrosis, and dysplastic hepatocytes. Th...
