Abstract
Lithium is one of the most powerful and commonly used medications for the treatment of various psychiatric diseases, especially bipolar disorder. However, it has a narrow therapeutic index with toxic effects on various organs. There are several case reports of lithium-induced arrhythmia and ischemia. The current work aimed to study the toxic effects of lithium on the heart of adult albino rats and its molecular mechanisms and the ameliorating effect of N-acetyl cysteine (NAC). Sixty adult male Wistar albino rats were classified into four groups; control, NAC-treated received NAC 500 mg/kg/week dissolved in 1 ml 0.9% sodium chloride intraperitoneal, lithium-treated received 52.5 mg/kg/day of lithium carbonate dissolved in 1 ml 0.9% sodium chloride orally by gavage, and lithium-and-NAC-treated (group IV) received lithium and NAC in the previous doses. After 12 weeks, the rats of group III showed a significant accumulation of ascites and a decrease in the mean arterial blood pressure and electrocardiographic (ECG) findings of ischemia and arrhythmia. In addition, there was an elevation in cardiac biomarkers creatine kinase MB (CK-MB), cardiac troponin I (cTnI), and several histological lesions with a significant increase in the area % of Van Gieson, endothelial nitric oxide synthase (eNOS), and 8-hydroxy-2'-deoxyguanosine (8-OHdG) immunoreaction. There was significant upregulation of microRNA-1, microRNA-21 (miRNA-21), and microRNA-29 (miRNA-29). MiRNA-21 was strongly positively correlated to the area % of 8-OHdG, while miRNA-29 was strongly positively correlated to the area % of Van Gieson staining. NAC significantly improved the cardiotoxic effects of lithium. Being a nontoxic and safe antioxidant, NAC can be used to ameliorate lithium-induced cardiac injury.

Abstract
Lithium is one of the classical drugs that have been widely used for treating bipolar disorder. However, several cardiac side effects including sick sinus syndrome, bundle branch block, ventricular tachycardia/fibrillation, non-specific T-wave abnormalities in addition to Brugada-type electrocardiographic changes have been noticed in patients who were given antidepressant, anticonvulsant, and/or antipsychotic drugs besides lithium. In this study, we assessed cardiohemodynamic and electrophysiological effects of lithium carbonate by itself to begin to analyze onset mechanisms of its cardiovascular side effects. Lithium carbonate in intravenous doses of 0.1, 1, and 10 mg/kg over 10 min was cumulatively administered with an interval of 20 min to the halothane-anesthetized beagle dogs (n = 4), which provided peak plasma Li+ concentrations of 0.02, 0.18, and 1.79 mEq/L, respectively, reflecting sub-therapeutic to toxic concentrations. The low and middle doses prolonged the ventricular effective refractory period at 30 min and for 5-30 min, respectively. The high dose decreased the heart rate for 45-60 min, delayed the intraventricular conduction for 15-20 min and the ventricular repolarization at 45 min, and prolonged the effective refractory period for 5-60 min. No significant change was detected in the other cardiovascular variables. Thus, lithium alone may have a wide safety margin against hemodynamic adverse events; however, it would directly and/or indirectly inhibit Na+ and K+ channels, which may synergistically increase the ventricular refractoriness from the sub-therapeutic concentration and decrease the heart rate at the supra-therapeutic one. These findings may partly explain its clinically observed various types of arrhythmias as well as electrocardiographic changes.

Abstract
Mitochondria play an important role in myocardial tissue homeostasis; therefore, deterioration in mitochondrial function will eventually lead to cardiomyocyte and endothelial cell death and consequently cardiovascular dysfunction. Lithium (Li+ ) is an effective drug for bipolar disorder with known cardiotoxic side effects. This study was designed to investigate the effects of Li+ on mitochondria and cardiomyocytes isolated from the heart of Wistar rat. Results revealed that Li+ induced a concentration- and time-dependent rise in mitochondrial ROS formation, inhibition of respiratory complexes (II), mitochondrial membrane potential (MMP) collapse, mitochondrial swelling, and cytochrome c release in rat heart mitochondria and also induced Caspase 3 activation through mitochondrial pathway, decline of ATP and lipid peroxidation in rat cardiomyocytes. These results indicate that the cardiotoxic effects of Li+ were initiated from mitochondrial dysfunction and oxidative stress, which finally ends in cytochrome c release and cell death signaling heart cardiomyocytes.

Abstract
Lithium is a potent psychotherapeutic agent that has gained wide acceptance in paediatrics, especially as adjunct treatment for severe behavioural, anxiety, and attention-deficit hyperactivity disorders, along with bipolar conditions. Its cardiac toxicity has been well-documented in adults; however, information is limited regarding lithium's effects on the heart in children. Therefore, paediatric cardiologists following-up children on lithium therapy should be cognizant of the cardiac side-effects and pathophysiology associated with this drug. In this manuscript, we used an illustrative case of a child who presented with lithium poisoning, in order to highlight adverse clinical manifestations that can arise from this medication. The cardiac cell membrane is thought to be the primary site of lithium's action. Thus, we reviewed lithium's effects on membrane electrogenic pumps and channels involved in the distribution and passage of sodium, potassium, and calcium across the sarcolemma, as these ions, and their associated currents, are the primary determinates of the action potentials underlying auto-rhythmicity and contractile activity of the heart.

Abstract
Conditioned taste aversion (CTA) is a well-established learning paradigm, whereby animals associate tastes with subsequent visceral illness. The prelimbic cortex (PL) has been shown to be involved in the association of events separated by time. However, the nature of PL activity and its functional network in the whole brain during CTA learning remain unknown. Here, using awake functional magnetic resonance imaging and fiber tracking, we analyzed functional brain connectivity during the association of tastes and visceral illness. The blood oxygen level-dependent (BOLD) signal significantly increased in the PL after tastant and lithium chloride (LiCl) infusions. The BOLD signal in the PL significantly correlated with those in the amygdala and agranular insular cortex (IC), which we found were also structurally connected to the PL by fiber tracking. To precisely examine these data, we then performed double immunofluorescence with a neuronal activity marker (c-Fos) and an inhibitory neuron marker (GAD67) combined with a fluorescent retrograde tracer in the PL. During CTA learning, we found an increase in the activity of excitatory neurons in the basolateral amygdala (BLA) or agranular IC that project to the PL. Taken together, these findings clearly identify a role of synchronized PL, agranular IC, and BLA activity in CTA learning.

Abstract
The physiological responses of juvenile rainbow trout (Oncorhynchus mykiss) to lithium (as LiCl) in moderately hard freshwater (CaCO(3) = 120-140 ppm, Na(+) = approximately 0.6 mM) were studied. The study employed a 15-day step-up exposure regime; 66 microg/L Li for the first 9 days and 528 microg/L for the next 6 days. The concentrations of plasma ions, apolipoprotein AI, total cholesterol, and fatty acids, as well as metabolic enzyme citrate synthase (CS) and Na(+),K(+)-ATPase activities in the gill were measured. Li affected fish by exacerbated diffusive Na(+) losses at the gills in the beginning of exposure and a decrease of branchial CS activity. Detrimental effects were shown in fish exposed to 528 microg Li/L. These included a reduction of gill Na(+),K(+)-ATPase activity, possibly related to observed lower concentrations of free fatty acids and cholesterol in gill tissue.

Abstract
The effects of ATP-sensitive potassium channels on lithium induced state-dependent memory of passive avoidance task were examined in mice. The pre-training (5 mg/kg) and pre-test (5 mg/kg) injection of lithium impaired memory retrieval on the test day. Impairment of pre-training lithium was restored by pre-test administration of lithium (5 mg/kg), diazoxide, an ATP-sensitive potassium channel opener, (15, 30 and 60 mg/kg) or glibenclamide, an ATP-sensitive potassium channel blocker, (6 and 18 mg/kg). Pre-test administration of inactive doses of lithium (2.5 and 10 mg/kg) plus lower and inactive dose of glibenclamide (2 mg/kg) or diazoxide (1.5 mg/kg) also reversed the amnesia induced by pre-training lithium (5 mg/kg). In conclusion, the ATP-sensitive potassium channel opener or blocker not only mimicked the effect of lithium in state-dependent learning in the absence of lithium on the test day, but also potentiated the effect of low dose of lithium in restoration of memory. Therefore, ATP-sensitive potassium channels may have a modulatory influence on lithium response.

Abstract
We investigated lithium-induced changes in norepinephrine (NE) catabolism. NE and its major metabolites 3-methoxy-4-hydroxyphenylglycol (MHPG) and 3,4-dihydroxyphenyl glycol (DHPG), ions such as lithium (Li(+)), magnesium (Mg(2+)), and potassium (K(+)) were measured in rat plasma and cerebral cortex using an HPLC method with electrochemical detection for amines. The results obtained with a group of rats treated by lithium chloride (2 mmol/kg/IP) were compared with a control group receiving sodium chloride (2 mmol/kg/IP). Animals were killed at different times over a period of six hours in the morning following salt administration to minimize possible chronobiological effects. There are two pathways leading to MHPG formation: way A, without DHPG, and way B, with DHPG. In plasma and cerebral cortex of lithium treated rats, way A catabolism seems to be preferential. Lithium increases Mg(2+) and K(+) plasma levels. These results suggest that lithium may increase inactivation of NE and decrease NE available for adrenergic receptors.
