Abstract
Lithium (Li) is a typical mood stabilizer and the first choice for treatment of bipolar disorder (BD). Despite an extensive clinical use of Li, its mechanisms of action remain widely different and debated. In this work, we studied the time-course of the therapeutic Li effects on ouabain-sensitive Na+/K+-ATPase in forebrain cortex and hippocampus of rats exposed to 3-day sleep deprivation (SD). We also monitored lipid peroxidation as malondialdehyde (MDA) production. In samples of plasma collected from all experimental groups of animals, Li concentrations were followed by ICP-MS. The acute (1 day), short-term (7 days) and chronic (28 days) treatment of rats with Li resulted in large decrease of Na+/K+-ATPase activity in both brain parts. At the same time, SD of control, Li-untreated rats increased Na+/K+-ATPase along with increased production of MDA. The SD-induced increase of Na+/K+-ATPase and MDA was attenuated in Li-treated rats. While SD results in a positive change of Na+/K+-ATPase, the inhibitory effect of Li treatment may be interpreted as a pharmacological mechanism causing a normalization of the stress-induced shift and return the Na+/K+-ATPase back to control level. We conclude that SD alone up-regulates Na+/K+-ATPase together with increased peroxidative damage of lipids. Chronic treatment of rats with Li before SD, protects the brain tissue against this type of damage and decreases Na+/K+-ATPase level back to control level.

Abstract
One of the remarkable discoveries in the field of psychopharmacology from late 1940s is Lithium (Li) that reminds of old but still gold. It continues to be a distinctive mood stabilizer that matches various standards recommended for mood stabilizers. Apart from this Li is also known to affect immune cell functions. Lithium response and regulations of different immune cells in bipolar patients, related immune disorders are not well defined. Here, we provide an overview of literature with regard to Li's effects on different immune cells. However, the use of Li is currently limited to bipolar disorders and there is no empirical evidence for immune cell disorders. The objective of this article is to provide the evaluations of Li responses towards the different immune cells based on the existing studies. Further, more studies are needed to understand the mechanistic basis and heterogeneous responses of Li's effect in bipolar, also unravel relative immune disorders.

Abstract
We examined how lithium's demonstrated effects on various cellular processes in human brain would be reflected in the (31)P magnetic resonance spectra of living human beings with respect to brain high-energy phosphate metabolites. Eight healthy volunteers received a baseline (31)P magnetic resonance spectroscopy (MRS) scan, after which they received lithium carbonate, 900 mg/day, for 14 days. Follow-up MRS scans were obtained on day 7 and on day 14. We detected a lithium-induced decrease in alpha-, beta-, gamma- and total nucleoside triphosphate NTP levels with chronic administration of lithium. On day 7, significant decreases were noted in gamma-NTP (14%) and total NTP (11%) levels. There was a trend for a decrease in beta-NTP (11%) levels. On day 14, significant decreases were noted in alpha-NTP (7%) and total NTP (8%) levels. There was a trend for a decrease in beta-NTP (16%) levels. Lithium caused a 25% reduction in inorganic phosphate (P(i)) levels on day 14. The theoretical relevance of the lithium-induced alterations on brain high-energy phosphates to the lithium-induced modifications of neuroplasticity is discussed.

Abstract
In this article, we discuss and highlight some of the potential neurochemical underpinnings of bipolar disorder (BD) and epilepsy. Some similarities are found in both disorders, such as the episodic course of the illnesses, the possible mechanism of kindling, and the efficacy of some antiepileptic drugs (AEDs) in treatment, all pointing to a common underlying pathophysiology. Common mechanisms at the level of ion channels might include the antikindling and the calcium-antagonistic and potassium outward current-modulating properties of AEDs. However, future research on intracellular mechanisms might become decisive for a better understanding of the similarities between the disorders.

Abstract
Bipolar disorder has attracted numerous research from different neurobiological angles. This review will summarize selected findings focusing on the role of disturbed transmem-braneous ion fluxes. Several mood stabilizers exhibit a distinct profile including effects on sodium, calcium and potassium conductance. In summary, some decisive mechanisms of action as calcium antagonism and modulation of potassium currents may play a crucial role in the success of any given mood stabilizer in bipolar disorder.

Abstract
Patients with manic depressive disorder (DSM-III-R bipolar disorder) have an abnormality of the Na+,K(+)-ATPase pumps in their lymphocytes: the pump numbers do not upregulate to stimulation with lithium and ethacrynate. We have now investigated the in vitro adaptive responses of lymphocyte Na+,K(+)-ATPase pumps in the first-degree unaffected relatives of patients with a clear history of manic depressive disorder. The lymphocytes of the healthy relatives upregulated their Na+,K(+)-ATPase pumps normally, suggesting that the abnormal response that we have previously observed in patients with the disorder reflects a complex relation between the biochemical phenotype and the development of clinical symptoms.

Abstract
Lithium is well established as a treatment of manic-depressive illness. As for the mechanism of action of lithium, it is proposed that lithium has effects on intracellular calcium ion (Ca2+) movement. But there are few reports in which the effects of lithium on intracellular Ca2+ movement are observed in the mammalian brain. We therefore examined the effects of lithium on intracellular Ca2+ changes in the rat hippocampal slices with a Ca2+ sensitive dye fura-2, and analyzed by means of a fluorescence microscope, a video-camera and photometrical devices. From the results of treatment with various noradrenergic agonists or antagonists, noradrenaline (NA)-induced intracellular Ca2+ change appears to be mainly mediated by alpha 1-adrenoceptors (AR) rather than alpha 2- or beta-AR. Furthermore, they are considered to be mediated by both alpha 1A-AR and alpha 1B-AR, and to be partly dependent on extracellular Ca2+. Lithium decreased NA-induced intracellular Ca2+ mobilization by attenuation of T1/2 rather than a change in the peak value, and antagonized ouabain-induced intracellular Ca2+ increase. Lithium may therefore suppress intracellular Ca2+ movement by enhancing the extrusion of intracellular Ca2+.

Abstract
A cellular model for bipolar illness is presented. It is propounded that alterations in the activity of the membrane sodium- and potassium-activated adenosine triphosphatase pump (Na,K-ATPase) may be responsible for alterations in neuronal excitability and activity. Specifically, a reduction in Na,K-ATPase activity can lead to both mania and depression by increasing membrane excitability and decreasing neurotransmitter release, respectively. Supporting evidence is reviewed, and clinical and research implications are discussed.

Abstract
Forty-four subjects with a history of a major recurrent affective disorder in remission and who were either on no medication or taking a single dose of psychotropic medication were conscripted together with matched controls. The fluorescent indicator fura 2 was used to measure intracellular calcium in platelets and estimations were made of total serum and ionised calcium as well as of whole blood serotonin. Intracellular calcium was measured in the resting state as well as after stimulation with thrombin, platelet activating factor and serotonin. No significant differences were found between the 17 subjects with a diagnosis of bipolar disorder or the 27 subjects with recurrent unipolar depression and their matched controls. Intracellular calcium measures were significantly higher in the lithium treated group after stimulation with 5HT, whereas the subjects taking tricyclic antidepressants did not differ significantly from their controls on any measure. Serum calcium was found to be significantly higher in those subjects taking lithium. These findings suggest that the measurement of intracellular calcium is not a useful trait marker in affective disorders. Lithium appears to enhance the 5HT induced rise of intracellular calcium.

Abstract
1. We have measured [3H]-ouabain binding to lymphocyte membranes in eight healthy volunteers before and after they had taken lithium carbonate for 14 days in doses which maintained the serum lithium concentration in the range 0.5-1.0 mmol 1-1. 2. There was a statistically significant increase in the [3H]-ouabain binding capacity of the lymphocyte membranes (reflecting the number of Na+, K+-ATPase molecules) after 14 days of lithium administration in vivo. This suggests that a failure to increase pump numbers after similar exposure to lithium in vivo in patients with manic-depressive psychosis is a primary abnormality associated with the disease. 3. In vivo lithium administration did not alter the normal adaptive (upregulatory) response of lymphocyte Na+, K+-ATPase to standard pharmacological challenges, involving in vitro incubation for 3 days with lithium chloride (8 mmol 1-1) or sodium ethacrynate (1 mumol 1-1). 4. We have previously found that there is an impaired response of the Na+, K+-ATPase to these in vitro stimuli in patients with manic-depressive psychosis, and our present data suggest that this abnormality is attributable to the disease itself and not to in vivo lithium therapy. 5. The data also suggest that the increase in vivo Na+/K+ pump activity which we have previously described in healthy volunteers after 21 days of lithium administration is at least partly due to an increase in Na+/K+ pump numbers.

Abstract
When lymphocytes from healthy subjects are incubated in lithium (8 mM) or ethacrynate (1 microM) they show a time-dependent adaptive response, which consists of a significant increase in the number of Na+,K(+)-ATPase molecules in the lymphocyte membrane. We have studied the lymphocytes from nine euthymic drug-free patients with a history of manic depressive psychosis, and have found that this normal adaptive response was absent. It was also absent from the lymphocytes of euthymic patients taking lithium. We conclude that this altered in vitro adaptive response of lymphocyte Na+,K(+)-ATPase represents an enduring trait marker in manic depressive psychosis.
