BACKGROUND One of the major morphologic characteristics of hepatitis B is a hepatocellular regeneration which is induced by massive hepatocyte necrosis and associated with proliferative activity of hepatocytes. The purpose of this study is to document the proliferative activity of hepatocytes in various types of hepatitis B by immunohistochemical staining for proliferative cell nuclear antigen-...

Animal model : To study the possibility of a viral transmission through the use of the air pressure injector, we have chosen the mouse hepatitis viral infection as a mouse model since this virus is highly infectious and induces a fulminant hepatitis leading to a rapid death in selected mouse strains. The serotype 3 of MHV strain is the most virulent strain of this virus and induces hepatitis in...

Hepatitis B virus (HBV) infection is a worldwide problem and can cause acute liver failure, acute hepatitis, chronic hepatitis, liver cirrhosis, and liver cancer. In areas of high prevalence such as in Asia, Africa, southern Europe, and Latin America, the hepatitis B surface antigen positive rate ranges from 2% to 20%.In endemic areas, HBV infection occurs mainly during infancy and early childh...

Introduction. Hepatitis A virus is the most common cause of acute viral hepatitis, and in people over 25 years age disease may have different degrees severity. Even though hepatitis infection was long believed to be transmitted strictly by fecal-oral route, now this classified among sexually diseases. Homosexual population, especially those positive for human immunodeficiency virus, at greatest...

UNLABELLED Hepatitis E virus (HEV) causes acute enterically transmitted hepatitis. In industrialized countries, it is a zoonotic disease, with swine being the major reservoir of human HEV contamination. The occurrence and severity of the disease are variable, with clinical symptoms ranging from asymptomatic to self-limiting acute hepatitis, chronic infection, or fulminant hepatitis. In the abse...

background although certain hbv mutations are known to affect the expression of hepatitis e antigen, their association with hbv viral level or clinical outcomes is less clear. objectives we evaluated associations between different mutations in the basal core promoter (bcp) and pre-core (pc) regions of hbv genome and subsequent changes in hbv viral dna level over seven years in a population of u...

background hepatitis c virus (hcv) infection is one the major health concern among the infected transplant patients. considering several complications of the disease in them, pre and post-transplantation studies should be performed for monitoring of the infection, as well as, developing new treatment protocols. objectives the current study was conducted to determine the hepatitis c virus rna le...

Eighty consecutive cases of acute viral hepatitis and 80 controls selected from a public pediatric clinic were entered into a study of acute sporadic hepatitis in Khartoum, Sudan. Study subjects were 14 years of age or younger and were mainly from a low socioeconomic level. Non-A, non-B hepatitis was diagnosed by exclusion in 35 (43.8%) patients, hepatitis A in 27 (33.8%), acute hepatitis B in ...

background: hepatitis a, an acute viral disease is the most common global cause of viral hepatitis that affects millions of people annually. due to its high incidence, hepatitis a is considered a worldwide health problem. this study aims to determine the knowledge, risk perceptions, and behavioral intentions for hepatitis a among elementary school teachers in yazd city. â  materials and methods...

The aim of the study was to assess the prevalence of depression among Croatian patients infected with human immunodeficiency virus (HIV) and to make a comparison with patients with other acute and chronic infectious diseases. We assessed the depressive disorder using the Beck Depression Inventory questionnaire (BDI), without clinical confirmation. The BDI scores were examined in 80 HIV-infected...
