[ 1 ] - Surface protein mutations in chronic hepatitis B patients who received hepatitis B vaccine therapy
Objective (s):The aim of this study was to determine the correlation between vaccine therapy and appearance of mutations in hepatitis B surface antigen (HBsAg)-positive chronic hepatitis B virus (HBV) patients. Materials and Methods: 16 patients received the HBV vaccine and another 16 individuals from the control group did not. The surface gene was amplified and directly sequenced from samples...
[ 2 ] - Hepatitis B Virus Surface Antigen Variants Clustered Within Immune Epitopes in Chronic Hepatitis B Carriers from Hormozgan Province, South of Iran
Objective(s) The aim of this study was to characterize the hepatitis B virus surface protein genotypes and sequence variations among hepatitis B virus surface antigen (HBsAg) positive chronic patients in Hormozgan province, south of Iran.

[ 3 ] - Antibacterial Activity of Twenty Iranian Plant Extracts Against Clinical Isolates of Helicobacter pylori
Objective(s) Due to increasing emergence of drug-resistance in Helicobacter pylori isolates, traditional plants are potentially valuable sources of novel anti-H. pylori agents. In this research, anti-H. pylori activity of the organic extracts of twenty native Iranian plants was determined against ten clinical isolates of H. pylori. Materials and Methods Disc diffusion was used to determine th...
