objective(s): according to the occupationally risk of infection in staff workers who have direct contact with mycobacterium species, we investigated their immunological parameters and compared with healthy purified protein derivative (ppd) negative volunteers.   materials and methods : we investigated 20 ppd positive volunteers working at tuberculin unit of razi vaccine and serum research insti...

For demonstration of cell-mediated immunity and its role in the process of dermatophytosis, 98 patients with acute dermatophytosis (group I) and 131 chronic dermatophytosis patients (group 2) were chosen. In ail patients, lymphocyte transfonnation and skin test were used. 96 members of group I (98%) had positive delayed-type hypersensitivity (DTH) responses to trichophytin, whereas only 43 ...

objective: evaluation of bax encoding plasmid for increasing efficacy of dna vaccine plasmid encoding gb of herpes simplex virus type 1. materials and methods: we compared three different dosages of bax encoding plasmid (pcbax) including 10, 25 and 50 μg of plasmid dna. they were co-injected ineradermally with glycoprotein b (gb) of herpes simplex virus (hsv)-1 encoded plasmid (pcgb) in c57bl/6...

Backgrounds: Most of the hepatitis C virus (HCV) infections elicit poor immune responses and 75% to 85% of cases become chronic therefore, the development of an effective vaccine against HCV is of paramount importance. In this study, we aimed to evaluate co-administration of HCV non-Structural Protein 2 and IL-12 DNA vaccines in C57BL/6 mice. Methods: A plasmid encoding full-length HCV NS2 prot...

Background: Hepatitis C (HCV) is a worldwide problem without an effective vaccine with more than 170 million chronically infected people worldwide. DNA vaccines expressing antigenic portions of the virus with adjutants have recently been developed as a novel vaccination technology. Objectives: In the present study, a DNA vaccine expressing HCV core protein was developed with IL12 as a genetic a...
