BIOLOGY OF ZEBRAFISH, Danio rerio
ثبت نشده
چکیده
Zebrafish, Danio rerio (Hamilton), is one of the most important vertebrate model organism in genetics, developmental biology, neurophysiology and biomedicine (Rubinstein, 2003; Amsterdam and Hopkins, 2006). It is a small, robust fish, so large numbers can be kept easily and cheaply in the laboratory, where it breeds all year round. Development is rapid, with precursors to all major organs developing within 36 hr and larvae displaying food seeking and active avoidance behaviours within five days post fertilization, i.e. 2-3 days after hatching (Kimmel et al., 1995)

Effect of Cadmium Chloride on Maturity of Female Zebrafish (Danio rerio) using Vitellogenin Biomarker and Ovary Histopathology
This study aimed to investigatethe changes in Gonad Somatic Index (GSI), vitellogenin induction and ovarian histopathology in zebrafish (Danio rerio) adult female, as an ecological model in toxicology, after exposure to 0.002, 0.02, 0.2, 2 and 20 µg/L cadmium chloride for 21 days under sub-lethal condition. The results showed that 0.002 to 20 µg/L cadmium chloride had no significant effect on t...

Paraben compounds are used widely as preservatives to inhibit microbial growth and extend used in pharmaceuticals, hygienic, cosmetics, care products. They pose the potential for reproductive toxicity for users. This paper provides an overview of the applications of histopathological biomarkers in reproductive toxicity in zebrafish caused by methylparaben. The present study investigated the cha...
متن کاملEvaluation of of the performance of the zebrafish (Danio rerio) model in nanotoxicology studies with emphasis on embryo pathology
The present study was conducted to evaluate the performance of zebrafish (Danio rerio) as a model in embryo and fetal pathology in nanotoxicology studies. Examination of the sources showed that it is possible to completely inhibit hatching and fetal death when exposed to nanoparticles, because nanoparticles interact with hatching enzymes. Zebrafish embryo developmental abnormalities have been s...

Di(2-ethylhexyl)phthalate (DEHP) is a plasticizer in a variety of consumer products. Given the adverse toxicity effects of DEHP on living organisms, its high consumption and dispersal has been caused a serious concern. . Nowedays, the Fish Embryo Test (FET) method is widely used among the conventional methods of toxicology .The aim of the this study was to determine the acute toxicity of Di(2-e...
متن کاملA review of the performance of zebrafish (Danio rerio) as a model organism in nanotoxicological research and its differences with other animal models
Today, nanotechnology is recognized as one of the leading sciences in the world, which manipulates atoms and molecules in order to produce valuable products. Extensive use of nanomaterials in various industrial sectors has increased the possibility of their diffusion in water bodies and the environment. Therefore, the study of toxicity of these substances is considered as one of the research ne...
