| Résumé en anglais |
In crayfish, the hemolymph glucose level shows an endogenous circadian rhythmicity which is expressed by a nocturnal glucose rise. This study shows that injections of serotonin and dopamine result in hyperglycemia and that injections of met-enkephalin decrease hemolymph glucose level as well as the nocturnal circadian glucose peak. Using immunocytochemistry, these neurotransmitters have been located in the eyestalk and their relationship with the CHH cell system is described. |
