Response to Dr. Rosenquist's comments pertaining to the paper by Andaloro et al. ('98) "Dextromethorphan and other N-methyl-D-aspartate receptor antagonists are teratogenic in the avian embryo model" and letters to the editor by Polifka JE and Shepard TH ('98) and Brent RL ('98) 1999

UI	MeSH Term	Description	Entries
D008954	Models, Biological	Theoretical representations that simulate the behavior or activity of biological processes or diseases. For disease models in living animals, DISEASE MODELS, ANIMAL is available. Biological models include the use of mathematical equations, computers, and other electronic equipment.

D002642	Chick Embryo	The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching.	Embryo, Chick,Chick Embryos,Embryos, Chick
D003915	Dextromethorphan	Methyl analog of DEXTRORPHAN that shows high affinity binding to several regions of the brain, including the medullary cough center. This compound is an NMDA receptor antagonist (RECEPTORS, N-METHYL-D-ASPARTATE) and acts as a non-competitive channel blocker. It is one of the widely used ANTITUSSIVES, and is also used to study the involvement of glutamate receptors in neurotoxicity.	d-Methorphan,Delsym,Dextromethorphan Hydrobromide,Dextromethorphan Hydrobromide, (+-)-Isomer,Dextromethorphan Hydrobromide, Monohydrate,Dextromethorphan Hydrochloride,Dextromethorphan, (+-)-Isomer,Racemethorphan,Hydrobromide, Dextromethorphan,Hydrochloride, Dextromethorphan
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D000996	Antitussive Agents	Agents that suppress cough. They act centrally on the medullary cough center. EXPECTORANTS, also used in the treatment of cough, act locally.

D013723	Teratogens	An agent that causes the production of physical defects in the developing embryo.	Embryotoxins,Fetotoxins,Teratogen
D016194	Receptors, N-Methyl-D-Aspartate	A class of ionotropic glutamate receptors characterized by affinity for N-methyl-D-aspartate. NMDA receptors have an allosteric binding site for glycine which must be occupied for the channel to open efficiently and a site within the channel itself to which magnesium ions bind in a voltage-dependent manner. The positive voltage dependence of channel conductance and the high permeability of the conducting channel to calcium ions (as well as to monovalent cations) are important in excitotoxicity and neuronal plasticity.

D018691	Excitatory Amino Acid Antagonists	Drugs that bind to but do not activate excitatory amino acid receptors, thereby blocking the actions of agonists.
