Some types of verrucae of human skin have long been known to be caused by a filterable infectious agent (1), and as such, represent the only kind of tumorous growth in man definitely known to be virus-induced. Warts of this kind, characterized cytologically by intranuclear inclusion bodies and cytoplasmic masses (2--4) have been shown to yield crystalline viral particles (5). The cytology and h...

Background: Formaldehyde is a chemical that used in fixed tissues and bodies. Formaldehyde during dissection of cadaver, evaporate and be released. Studies have shown that the gas increase endogenous opioids, nitric oxide and cytokines in plasma. These impacts can affect on gonadotropin hormones. The aim of this study was to investigate possible changes in gonadotropin and epithelial cells of t...

background and aims: inclusion body hepatitis (ibh) is one of the most important reemerging diseases in many countries with intensive poultry industries. in iran, the etiological agent of ibh (fowl adenovirus) has not been yet confirmed. the aim of this study was the molecular detection and identification of fowl adenovirus involving ibh in chicken flocks in iran. materials and methods: polymer...

AIMS Histologically diagnosed cytomegalovirus (CMV) infection of the cervix is rare and the associated morphological features are not well described. This study describes histopathological findings in five biopsies from four patients with CMV cervicitis. METHODS CMV inclusions were identified in five cervical biopsies from four patients in a single institution over eight months. The clinical ...

Evidence is accumulating that herpes simplex virus (HSV) infection is implicated in oncogenesis. HSV antigens have been observed in some oral cancers. We present the case of a 62-year-old man who presented with dysphagia, odynophagia, and dysphonia and who was found on computed tomography (CT) to have a mass in his piriform sinus. We suspected a malignancy, but histopathology of biopsy specimen...

Severe tracheitis and bronchitis were identified in two fatal cases of respiratory disease affecting a flock of Gouldian finches (Erythrura [Chloebia] gouldiae). Intranuclear inclusion bodies in epithelial cells of the upper respiratory tract were identified in samples from two birds. Electron microscopic examination showed that the inclusions consisted of viral particles consistent in appearan...

The intracellular bioavailability of lead (Pb) at low dosage levels in major target organs such as the kidney and brain appears to be largely determined by complexation with a group of low molecular weight proteins. These proteins are rich in aspartic and glutamic dicarboxyl amino acids. The proteins are chemically similar but not identical across all species examined to date and the brain prot...
