Role of the herpes simplex virus 1 internal repeat sequences in pathogenicity.

abstract：BACKGROUND:Many efforts are currently focused on functional treatment of the hepatitis B virus (HBV). This can be done by suppressing the secretion of HBV surface antigen (HBsAg). Scientific communities are very interested in natural products in that respect. OBJECTIVE:Use of root extract of Havachoobe (Onosma dichroa...
