Stability of rubella virus after long-term persistence in human cell line.

Use of human diploid cell MRC - 5, for production of Measles and Rubella virus vaccines

Evaluation of Cell Mediated Immunity following Rubella Vaccination Using Lymphocyte Proliferation

Background and Aims: Rubella is predominantly a childhood disease that is endemic throughout the world and when rubella outbreaks occur, they are accompanied by birth defects following congenital rubella syndrome. Immunity to rubella virus as a teratogenic agent has an important role for prevention of these serious congenital defects. Lymphocyte proliferation assay is a way for investigation of...

Cytotoxicity of Subtoxic AgNP in Human Hepatoma Cell Line (HepG2) after Long-Term Exposure

Background: We aimed at evaluating the toxicity effects of low (subtoxic) concentrations of silver nanoparticles (AgNP, 5-10 nm) in human hepatoblastoma (HepG2) cell line after and during a period of about one month. Methods: XTT and MTT assays were used to draw a dose-response curve IC50 (half maximal inhibitory concentration) value of the AgNP on HepG2 cells was calculated to be 2.75-3.0 mg/l...

Stability Study of Measles AIK-C Strain, Mumps RS-12 Strain and Rubella Takahashi Strain in MMR Vaccine

Stability studies play a critical role in assuring product quality at all points in the vaccine life cycle and havea major impact on the success of immunization programs worldwide. The purpose of stability study isdetermination of the vaccine quality under the variety of environmental factors and to establish a re-testperiod or a shelf life and recommended storage conditions. In this study thre...

Estimation of the Cultured Cells’ Volume and Surface Area: Application of Stereological Methods on Vero Cells Infected by Rubella Virus

Background: Morphological changes of the cells infected with rubella virus cannot be observed easily. Estimation of the size of the cultured cells can be a valuable parameter in this condition. This study was conducted to find answers to the following questions:How much time after infection with rubella virus, the volume and surface area of the Vero cells and their nuclei get started to change?...
