Effects of cycloheximide administered in conjunction with nicotine on retention of a passive avoidance task in mice. 1980

E R Stamm, and K Schlesinger

Retention of a passive avoidance task was studied in mice given either cycloheximide or cycloheximide in combination with nicotine. Two similar experiments were conducted: In the first experiment, the effects, of these drugs were studied in inbred C57Bl/6J mice. In the second experiment, the effects of these drugs were studied in genetically heterogenous mice. Cycloheximide was found to have a deleterious effect on retention of the passive avoidance task. Larger doses of cycloheximide were found to be necessary to disrupt memory in heterogenous mice than in C57Bl/6J animals. Nicotine, when administered in conjunction with cycloheximide, abolished the memory disruptive effects of cycloheximide. The results of these experiments are discussed in terms of a time-dependent consolidation model of memory storage.

UI MeSH Term Description Entries
D008568 Memory Complex mental function having four distinct phases: (1) memorizing or learning, (2) retention, (3) recall, and (4) recognition. Clinically, it is usually subdivided into immediate, recent, and remote memory.
D008810 Mice, Inbred C57BL One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases. Mice, C57BL,Mouse, C57BL,Mouse, Inbred C57BL,C57BL Mice,C57BL Mice, Inbred,C57BL Mouse,C57BL Mouse, Inbred,Inbred C57BL Mice,Inbred C57BL Mouse
D009538 Nicotine Nicotine is highly toxic alkaloid. It is the prototypical agonist at nicotinic cholinergic receptors where it dramatically stimulates neurons and ultimately blocks synaptic transmission. Nicotine is also important medically because of its presence in tobacco smoke. Nicotine Bitartrate,Nicotine Tartrate
D012153 Retention, Psychology The persistence to perform a learned behavior (facts or experiences) after an interval has elapsed in which there has been no performance or practice of the behavior. Psychological Retention,Retention (Psychology),Psychology Retention,Retention, Psychological
D003513 Cycloheximide Antibiotic substance isolated from streptomycin-producing strains of Streptomyces griseus. It acts by inhibiting elongation during protein synthesis. Actidione,Cicloheximide
D004305 Dose-Response Relationship, Drug The relationship between the dose of an administered drug and the response of the organism to the drug. Dose Response Relationship, Drug,Dose-Response Relationships, Drug,Drug Dose-Response Relationship,Drug Dose-Response Relationships,Relationship, Drug Dose-Response,Relationships, Drug Dose-Response
D005838 Genotype The genetic constitution of the individual, comprising the ALLELES present at each GENETIC LOCUS. Genogroup,Genogroups,Genotypes
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
