Teratogenic activity of methadone hydrochloride in mouse and chick embryos.

Investigation on the teratogenic and embryotoxic effects of nanozeolite on chick embryos model

Objective(s): In veterinary medicine, zeolites are used as toxin binder in animal feed, ammonia purification of aquatic pools, animal smell and moisture control. This study investigated on the risk assessment of nano zeolite on development of embryonic chicken models, anomalies, tetratogenic and embryotoxic effects. Methods: Eggs (120 = n) were accidentally di...

Effect of retinoic acid on neural tube development in chick embryo

retinoic acid is one of the derivatives of vitamin A.it is used for treatment of dermatitis,but it has different teratogenic effects on developing organs depending on the different stages of embryonic life.neural  tube is made of two different parts:primary neural tube originated from embryo germinal layer and and secondary neural tube originated from tail bud.the persent study was designed to ...

The Effect of chick Embryonic Somites on Neural Rosette Formation in Mouse Embryonic Stem Cells

purpose: The aim of the present study is to understand if EBs can generate neural rosette upon co-culture with chick embryo somites. Materials and Methods: The mouse ES cells, line Royan Bl, were cultured in hanging drops to induce embryoid bodies (EBs) formation. Somites were isolated from the chick embryos and then embedded in alginate solution. Finally, alginate beads containing somites were...

TERATOGENIC EFFECTS OF LITHIUM CARBONATE ON DEVELOPMENT OF MOUSE EMBRYOS

Comparison of teratogenic chemicals in the rat and chick embryos; an exhibit with additions for publication.

701 T HE CHICK EMBRYO 15 used widely in studying drugs for teratogenic activity. Chemicals, which have been injected at the same period of incubation of the chick eml)ryo, may produce separate and characteristic patterns of developmental abnormalities. The effects of many drugs, such as insulin, azasenine, sulfanilamide, 4-aminopteroyl glutamic acid, 8-azaguanine, physostigmine, thallium, lead,...
