Lithium slows neuronal calcium regulation in the snail Helix pomatia. 1985

J B Aldenhoff, and H D Lux

Steady-state and transient changes in intracellular calcium concentrations ([Ca2+]i) of snail neurons (Helix pomatia) were measured by the Ca2+ indicator Arsenazo(III) following manipulation of the extracellular concentration of lithium chloride (LiCl). Application of LiCl in concentrations equivalent to those used in the treatment of manic-depressive illness produces slowing in Ca2+ reequilibration after Ca2+-influx during depolarization, concomitantly with steady-state elevation of [Ca2+]i of about 100 nM, suggesting a change in Ca2+ reequilibration as a prominent action of LiCl. This mechanism may be relevant to the therapeutic effects of LiCl.

UI	MeSH Term	Description	Entries
D008094	Lithium	An element in the alkali metals family. It has the atomic symbol Li, atomic number 3, and atomic weight [6.938; 6.997]. Salts of lithium are used in treating BIPOLAR DISORDER.	Lithium-7,Lithium 7
D002118	Calcium	A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
