Purpose : To investigate the teratogenic potential of dopamine using a topical method of application to the developing Korean native chick embryo. Methods : A 5μg(0.05cc) of dopamine was applied to a 3-days-old chick embryo and the same amount of saline solution was applied as control. The embryo was then returned to the incubator and monitored. After 3 weeks the embryo was sacrificed and...
