A Slowing Down of Circadian Rhythms by Lithium Ions

Abstract: Unter the permanent influence of lithium ions the circadian rhythm of movement of Kalanchoe petals is effectively lengthened but a pulse administered up to 12 hours has no influence. Lithium ions could also be demonstrated to similarly slow down the circadian activity rhythm of a small mammal (Meriones crassus). It is hypothesized that the therapeutic effect of lithium salts in endogenous depressions in human beings may result also from its acting on the human circadian system

“…The free-running period length of the circadian rhythm increases slightly in mice given a daily dose of LiCl in water (44). If the target of LiCl was GSK-3␤ in that study, then our data are consistent with their findings because the effects of lithium might be explained as action on GSK-3␤ that regulates the circadian clock.…”

“…Behavioral data suggest that both deuterium oxide, i.e., 'heavy water' [Daan and Pittendrigh, 1976], and chronic lithium [Engelmann, 1973;Kripke et al, 1978Kripke et al, . 1980Strumwasser and Vielle, 1980;Johnsson et al, 1980;Katz, 1980] slow circadian pace makers.…”

“…1980). Lithium has been shown to delay the phase-positions of some behavioral circadian rhythms such as sleeping and waking in man [Engelmann, 1973;Johnsson el al., 1979Johnsson el al., , 1980, and the rest-activity cycle in the rat [Kripke and Wyborney, 1980] and to slow the rate of a circadian pacemaker cell in Aplysia [Strumwasser and Vielle, 1980]. Previous studies have documented that circadian rhythms in the number of rat brain a-and P-adrenergic [Kafka et al, 1981a], acetylcho line [Kafka et al, 1981b], dopaminergic [Naberct al.. 1980], and benzodiazepine [Marangos et al, in preparation] receptors are signif icantly modified by chronic administration of two drugs, which like lithium are antide pressant, viz., imipramine [Naber et al, 1980;Wirz-Justice et al, 1980a, b: Kafka et al.…”

“…Its period-lengthening effect on circadian rhythms has been documented in a great variety of species, e.g., desert cactus (8), cockroaches (15), molluscs (42}, hamsters (4,15), desert rats (8), rats (24,41), mice (33), squirrel monkeys (46), and humans (16). to the effect that the therapeutic effect of these drugs may be based on their phase delaying effect on the circadian pacemaker.…”
