## Abstract HTC cells incubated in the absence of serum for more than 14 hours have very low levels of ornithine decarboxylase, the first enzyme on the pathway of polyamine synthesis. Readdition of serum causes an increase in the activity of ODC, reaching a maximum on average 17 times above the bas

Abstract
Mixed neuronal and nonneuronal cell cultures were obtained from 8‐day‐old chick embryos cerebral hemispheres and glial‐enriched cultures were obtained from fifteen‐day‐old chick embryo cerebral hemispheres. Cultures were exposed to methadone, a narcotic drug, from days four to six. The activity of ornithine decarboxylase (ODC) was determined at day eight and the activity of cyclic nucleotide phosphohydrolase (CNP) was determined at day fifteen. Both ODC and CNP activity were higher in mixed neuronal‐nonneuronal cell cultures treated with methadone as compared to control. No effect was observed in the neuronal‐enriched or glial‐enriched cultures. These findings are interpreted to reflect that neuronal‐glial interaction is important in the response of primary neural cells to methadone.

Parkinson's disease is characterized by the progressive degeneration of midbrain dopaminergic neurons. Several studies have examined the effects of the dopaminergic neurotrophins growth/differentiation factor 5 (GDF5) and glial cell line-derived neurotrophic factor (GDNF) on these neurons in vitro.
