measles has been a major cause of illness and death in children and vaccination against the disease is part of the who global immunization program. a suitable vaccine should create maximum immune response against the pathogen and must be safe for the user. thus, after production, vaccines must be analyzed and controlled by the producer and confirm by relevant governmental organizations. the foo...

Twenty Serratia marcescens isolates from clinical specimens were examined for their cytotoxic activity on four cell lines (HEp-2, Vero, CHO, J774). Most of the isolates were found to be cytotoxic to CHO (70%), Vero (75%) and HEp-2 cells (90%). CHO cells were the most sensitive to cell-free supernatants, followed by HEp-2 and Vero cells. Two strains produced cytotonic toxins which caused elongat...

introduction: this study was started to improve in vitro blastocyst development and avoiding of blastocyst collapsment (no visibie cavity, returning of hatching blastocyst into zona pellucida, and tendency to degeneration). materials and methods: 24hrs one - cell mouse embryos were recovered from positive plug females and cultured in following canditions: experiments 1,2: during first 48hrs nmr...

Renal disorders have become very common nowadays, which may also lead to kidney failure. The disorder may be caused by the commonly used chemicals such as acetaminophen, CCl4, streptromycin, H2O2 etc. The objective of this work is to determine the nephroprotective potential of ethanolic extract against H2O2 induced toxicity in VERO cell line. Ethanolic extract is known for its antioxidant, anti...

vaccination against mumps is included in world health organization (who) program of global immunization. safety and efficacy of vaccines must be confirmed by control units in charge of public health. in iran, the secondary control on potency of vaccine has not been set up yet. we decided to overcome this problem by developing who and nibsc methods in food and drug control lab. ‎nine dilutions o...

introduction: the escherichia coli o157:h7 is considered an agent responsible for the outbreak of hemorrhagic colitis and the hemolytic uremic syndrome (hus). this serotype belongs to the subspecies of enterohemorrhagic e. coli (ehec). the ehec o157:h7 produces intimin, shiga toxins (stx1, stx2 or both). this study investigates the effect of thyme alcoholic extract on the growth and production ...

Of 30 cell lines and primary cells examined, productive severe acute respiratory syndrome coronavirus (Urbani strain) (SARS-CoV) infection after low-multiplicity inoculation was detected in only six: three African green monkey kidney epithelial cell lines (Vero, Vero E6, and MA104), a human colon epithelial line (CaCo-2), a porcine kidney epithelial line [PK(15)], and mink lung epithelial cells...

introduction: it is now generally accepted that vero cells provide beneficial effects on improving embryo quality in many animal species. the aim of this research was to determine the effect of vero cell co-culture on the development of vitrified 8-cell mouse embryos. material and methods: eight- cell mouse embryos were provided from superovulated female nmri mice and divided into treatment cas...
