Purpose: To create a probe for investigating neural development in chicks using magnetic resonance, a C3F7 tag was bonded to the indole ring of 5-hydroxytryptophan (5-HTP). Immunoassays indicate that a low dose (5 μg/egg) administered in ova results in 0.5-1.0 μg accumulating in a 250 μL midbrain. Procedures: Given the potential for developmental neurotoxicity of a compound that replaces an endogenous neurotransmitter, we investigated the effects of acute exposure during development. Results: No qualitative differences were observed between treatment groups. Differences in mortality rates between treatment groups were not statistically significant [ X2obs = 2.30, X2 crit (df=2)=5.99, P > 05]. Conclusion: The no-effect dose for in ova administration of C3F7 tagged5-HTP is 5 μg/egg on Day 17.
