Hepatitis Is an inflammation of the liver-colored and characterized by the presence of inflammatory cells in the wander of the organ. It damages the hepatocytes. And can kill the cells. By the tart deformity they usu onlyy recover complete. The condition can be cure by its own or can communicate to fibrosis and cirrhosis of the liver (fibrous tissue growth). The master(prenominal) so-called hepatitis viruses are a group hepatotrophic viruses.

The virus consist of an out lipide envelope and an icosahedral nucleocapsid ticker composed of protein. The small genome of HBV is do of circular DNA, the DNA is partially double-stranded. The viral envelope proteins contain HBsAG. The coat contains hepatitis B surface antigen (HBsAG), and the core contains a core antigen (HBcAG) and the e antigen (HBeAG), as well as viral DNA (HB DNA) and DNA polymerase (helps with catalyze). The transmission of HBV is drug...If you want to get a full essay, order it on our website: BestEssayCheap.com
