Abstract
BACKGROUND Takotsubo cardiomyopathy (TC), also known as stress-induced cardiomyopathy, has been increasingly described in relation to psychiatric illness. METHODS We performed a literature review to identify the key findings related to psychiatric illness in TC that may be relevant to the practice of mental health and other health care providers. RESULTS The association of psychiatric illness with TC in addition to the spectrum of psychiatric illness found in TC, the role of exacerbation or treatment of psychiatric illness in triggering TC, different modes of presentation, prognostic implications, and long-term management of psychiatric illness in TC are discussed. Additionally, we review the limitations of the pre-existing literature and suggest areas of future research. CONCLUSIONS There is a strong association between pre-existing psychiatric illness, particularly anxiety and mood spectrum disorders, and TC. Acute exacerbation of psychiatric illness, rapid uptitration or overdose of certain psychotropic agents, and electroconvulsive therapy may trigger TC. Further studies are needed to better evaluate the prognostic significance and long-term management of psychiatric illness in TC.

Abstract
According to the recently proposed vigilance model of affective disorders (vigilance in the sense of "brain arousal"), manic behaviour is partly interpreted as an autoregulatory attempt to stabilise vigilance by creating a stimulating environment, and the sensation avoidance and withdrawal in Major Depressive Disorder (MDD) is seen as an autoregulatory reaction to tonically increased vigilance. Indeed, using a newly developed EEG-based algorithm, hyperstable vigilance was found in MDD, and the contrary, with rapid drops to sleep stages, in mania. Furthermore, destabilising vigilance (e.g. by sleep deprivation) triggers (hypo)mania and improves depression, whereas stabilising vigilance, e.g. by prolonged sleep, improves mania. ADHD and mania have common symptoms, and the unstable vigilance might be a common pathophysiology. There is even evidence that psychostimulants might ameliorate both ADHD and mania. Hyperactivity of the noradrenergic system could explain both the high vigilance level in MDD and, as recently argued, anhedonia and behavioural inhibition. Interestingly, antidepressants and electroconvulsions decrease the firing rate of neurons in the noradrenergic locus coeruleus, whereas many antimanic drugs have opposite effects.

Abstract
Milnacipran is a serotonin noradrenaline reuptake inhibitor (SNRI) and is used clinically as an antidepressant. We report here the effect of milnacipran on catecholamine synthesis in cultured bovine adrenal medullary cells. Incubation of adrenal medullary cells with milnacipran (300 ng/ml, 1,065 nM) for 20 min resulted in a significant increase in 14C-catecholamine synthesis from [14C]tyrosine, but not from [14C]DOPA, whereas the selective serotonin reuptake inhibitors (SSRIs), paroxetine (300 ng/ml, 800 nM) and fluvoxamine (300 ng/ml, 691 nM), had little effect. Milnacipran, but not paroxetine or fluvoxamine, increased the activity of tyrosine hydroxylase, the rate-limiting step of catecholamine biosynthesis, in a concentration-dependent manner (100-300 ng/ml, 355-1,065 nM). U0126 (1 microM), an inhibitor of p44/42 mitogen-activated protein kinase (MAPK) kinase, abolished the stimulatory effects of milnacipran on tyrosine hydroxylase activity. Furthermore, incubation of cells with milnacipran (30-100 ng/ml) for 5 min activated p44/42 MAPK, whereas paroxetine and fluvoxamine did not. The present findings suggest that milnacipran activates tyrosine hydroxylase and then stimulates catecholamine synthesis through a p44/42 MAPK-dependent pathway in cultured bovine adrenal medullary cells.

Abstract
Lithium has acute and chronic effects on the hypothalamic-pituitary-adrenal gland (HPA) axis that are important for both therapeutic (e.g., treatment of mood disorders) and experimental (e.g., as the toxin in conditioned taste aversion studies) applications. We visualized lithium-induced activation of the HPA axis in rats by the adrenal expression of inducible cAMP early repressor (ICER), which is activated by elevated intracellular cAMP. We have shown that 1) intraperitoneal lithium chloride (LiCl) induces transient expression of ICER and c-fos mRNAs in the rat adrenal cortex and increases plasma level of corticosterone; 2) the cortical expression of ICER mRNA by LiCl occurs in a dose-dependent manner; 3) adrenal induction of ICER expression is delayed compared with c-fos expression; 4) dexamethasone pretreatment (4 mg/kg) blocks corticosterone release and adrenocortical ICER induction either by systemic LiCl (76 mg/kg) or by restraint stress; and 5) intracerebroventricular LiCl (127 microg/5 microl) is sufficient for adrenocortical, but not medullary, ICER induction. These results suggest that adrenocortical ICER expression could serve as a reliable marker for lithium-induced activation of the HPA axis. Understanding the activation of immediate-early genes such as c-fos or ICER in response to a single LiCl injection is an important first step in understanding the long-term changes in gene expression elicited by lithium that are involved in its therapeutic and toxic effect. The pattern and mechanism by which lithium stimulates ICER transcription in the adrenal gland would serve as a useful model system in future studies of lithium.

Abstract
Environmental estrogenic pollutants are compounds that have been shown to have estrogenic effects on fetal development and reproductive systems. Less attention, however, has been paid to their influence on neuronal functions. We report here the effects of estrogenic pollutants on catecholamine synthesis in bovine adrenal medullary cells used as a model system of noradrenergic neurons. Treatment of cultured bovine adrenal medullary cells with p-nonylphenol and bisphenol A at 10 nM for 3 d stimulated [14C]catecholamine synthesis from [14C]tyrosine and tyrosine hydroxylase activity, an effect that was not inhibited by ICI 182,780, an antagonist of estrogen receptors. Significant effects of p-nonylphenol on [14C]catecholamine synthesis were observed at 0.1 nM, which is 45 times lower than that of the international regulatory standard (4.5 nM), and the maximum effects were around 10-100 nM. The concentrations (0.1-10 nM) used in the present study are similar to the range observed in rivers in the United States or Europe. On the other hand, short-term treatment of cells with 10 nM p-nonylphenol for 10 min also activated tyrosine hydroxylase, which was suppressed by U0126, an inhibitor of MAPK kinase. Furthermore, treatment of cells with p-nonylphenol for 5 min increased the phospho-p44/42MAPK in a concentration-dependent (1-1000 nM) manner, whereas p-nonylphenol (100 nm, 2 d) enhanced both levels of non-phospho- and phospho-p44/42MAPK. These findings suggest that short-term and long-term treatment of cells with estrogenic pollutants at environmental concentrations stimulates catecholamine synthesis and MAPK through an estrogen receptor-independent pathway.

Abstract
This study was conducted to determine if nitric oxide (NO) is involved in lithium-induced expression of c-Fos and inducible cAMP early repressor (ICER) in the adrenal gland. Rats received an intraperitoneal injection of isotonic lithium (76 mg/kg) with either an intracerebroventricle (i.c.v., 250 microg) or intraperitoneal (i.p., 30 mg/kg) N(omega)-nitro-L-arginine methyl ester (L-NAME) pretreatment. The adrenal expression of c-Fos and ICER was examined by in situ hybridization 1 h after the lithium injection. The cortical c-Fos/ICER expression induced by lithium was not modulated by L-NAME pretreatment. However, lithium-induced medullary expression of c-Fos was attenuated by central L-NAME, and ICER by systemic L-NAME. These results suggest that nitric oxide is, at least partly, involved in lithium-induced c-Fos/ICER expression in the adrenal medulla, and that central nitric oxide may play a different role from peripheral nitric oxide in lithium-induced activation of adrenal medulla.

Abstract
Patients with depersonalization disorder experience episodes in which they have a feeling of detachment from themselves. Symptoms of depersonalization may occur in individuals who have other mental disorders, or who have various medical conditions, or who have taken certain medications. A woman developed depersonalization symptoms after initiation of minocycline therapy. Her symptoms ceased after treatment was stopped and recurred when she restarted the drug. Medications that have been associated with causing symptoms of depersonalization are presented and the postulated pathogenesis by which some of these drugs induced depersonalization symptoms is discussed. Medication-associated depersonalization symptoms typically resolve once the inducing drug has been withdrawn.

Abstract
The aim of the current study was to investigate lithium action on adrenomedullary and adrenocortical functions and on serum ionic balance in rats. Three age-groups of male rats (juvenile: 30 days, adult: 100 days and aged: 3 years) were used. Each age-group of animal was exposed to short- (10 days) and long-term (25 days) treatments with lithium. Each age-group of rat received lithium at a dose 2mEq/kg body weight daily for 10 and 25 days. Each daily dose (2mEq) was divided equally into half (1 mEq) and each half was injected intraperitoneally twice (at 9 am and 9 pm) for both the durations of experiments. Control animals received physiological saline for similar duration of experiments. Thirty animals were used for each age-group and they were divided equally into 6 groups with 5 each. After termination of all the experiments rats were sacrificed and, adrenal glands were quickly dissected out and processed for epinephrine, norepinephrine and corticosterone estimations and, 3 beta-hydroxysteroid dehydrogenase (3 beta-HSDH) activity of the adrenal gland. Blood was drawn from the heart of each rat and, serum was collected and stored at -20 degrees C until assayed for lithium, calcium, sodium, potassium and corticosterone concentrations. The findings revealed that lithium in both short- and long-term treatments was maintained well within the therapeutic range (0.3-0.8 mEq/l) in all the age-groups of rats. This alkali metal caused depletions of both epinephrine and norepinephrine concentrations from adrenal glands, and elevations of corticosterone in both adrenal and blood serum of each age-group of rat (juvenile, adult and aged). Additionally adrenal 3beta-HSDH activity was also increased in all the age-groups of rats irrespective of duration of the treatments. Short-term treatment of lithium elevated only serum K+ level in juvenile and adult rats and, Ca+ level only in adult animals. Significant elevations of serum K+ and Ca+ levels were observed following long-term treatments of lithium in all the age group of rats. No significant change in serum Na+ level was recorded after lithium treatment, irrespective of duration of treatments, in any age-group of rats. The findings suggest that lithium action, in respect of adrenomedullary and adrenocortical functions and, serum ionic balance, may not be largely related to the age-group of rats and that, lithium acts on adrenomedullary activity probably by stimulating the release mechanism of epinephrine and norepinephrine from the adrenal gland of rats, but stimulates adrenocortical activity by stimulating both synthesis (including 3 beta-HSDH activity) and release of corticorterone. Simultaneously, lithium disturbs normal ionic balance by elevating K+ and Ca+ levels in all the age-group of rats. Thus, the antimanic drug certainly disturbs both adrenomedullary and adrenocortical functions and, serum ionic balance in all the age-group of rats.

Abstract
Lithium (Li +) treatment of NTera2/D1 (or hNT Neurons) in culture increases tyrosine hydroxylase (TH) expression in this cell-line [Zigova et al., (1999) Exp. Neurol., 157, 251-258]. It is not known if these Li + treated cells maintain TH expression once transplanted into the striatum of the hemiparkinsonian rats. hNT neurons were either treated with 1 mm LiCl or left untreated and then transplanted into the striatum of Sprague-Dawley rats. Some cells were exposed to the lithium for 24 h in culture while others were exposed only briefly (2-3 h) just prior to transplantation. We also examined whether Li + treatment of the animal after transplantation (0.24% w/w lithium carbonate in chow) was effective in increasing neuronal survival. One week after transplantation, the animals were perfused with 4% paraformaldehyde and immunocytochemistry was performed on 30 micro m sections through the transplant. Human nuclear matrix antigen immunostaining demonstrated that there was significantly better survival of cells in the group treated briefly with lithium compared to all other groups. Brief exposure to lithium resulted in a greater expression of TH in situ as well. Neuron specific enolase immunohistochemistry showed that there was extensive fibre outgrowth in all groups. These results suggest that brief Li + exposure may enhance survival to over 60% and increase TH expression of hNT Neurons transplanted in the hemiparkinsonian rat nearly three-fold.

Abstract
The expression of the neuronal nitric oxide synthase (nNOS) gene in the paraventricular (PVN) and supraoptic nuclei (SON) in rats with lithium (Li)-induced polyuria was examined by using in situ hybridization histochemistry. The state of the thyroid axis in these rats was also examined by in situ hybridization histochemistry for thyrotropin-releasing hormone (TRH) and thyroid-stimulating hormone (TSH) mRNAs and radioimmunoassay for circulating thyroid hormones. Adult male Wistar rats consuming a diet that contained LiCl (60 mmol/kg) for 4 weeks developed remarkable polyuria. The urine in the Li-treated rats was hypotonic and had a large volume and low ionic concentration. The nNOS mRNA in the PVN and SON was significantly increased in the Li-treated rats in comparison with that in control. The increased levels of the nNOS mRNA in the PVN and SON were confirmed by NADPH-diaphorase histochemical staining. There were no differences of TRH mRNA in the PVN, TSH mRNA in the anterior pituitary and plasma concentrations of free T3 and free T4 between Li-treated rats and control rats. These results suggest that Li-induced diabetes insipidus may activate nNOS in the PVN and SON without change of the thyroid axis.

Abstract
Profilin is known to bind to actin monomers (to regulate actin polymerization) and to phosphatidylinositol-4,5-bisphosphate (to inhibit hydrolysis by unphosphorylated phospholipase C-gammal). It was recently reported that profilin is overexpressed in glomerular mesangial cells (MC) of rats with anti-Thy-1.1-induced glomerulonephritis and is accumulated in the extracellular space around MC. In this study, the biologic activities of extracellular profilin were examined. Scatchard analysis indicated the existence of a single class of cell surface binding sites, with similar equilibrium dissociation constants for purified splenic profilin and recombinant profilin, in cultured rat MC. Profilin increased [(3)H]thymidine incorporation in a dose-dependent manner and produced additive effects on platelet-derived growth factor-induced [(3)H]thymidine incorporation. Profilin increased AP-1 DNA-binding activity in a concentration-dependent (ED(50) = 30 nM) and time-dependent manner after transient c-jun gene expression, as measured using gel-shift assays and competitive reverse transcription-PCR. Pretreatment of profilin with an anti-profilin inhibitory antibody suppressed profilin-induced AP-1 activation and [(3)H]thymidine incorporation. Furthermore, profilin induced rapid transient activation of protein kinase C, and staurosporine and H-7 reduced the profilin-induced activation of AP-1, suggesting protein kinase C-dependent activation of AP-1. These findings indicate that profilin in the extracellular space can bind to cell surface receptors of MC and act as an inducer of signal transduction. These results suggest that extracellular profilin may be involved in the progression of glomerular diseases, by affecting cell growth.

Abstract
The clinical findings on neural transplantation for Parkinson's disease (PD) reported thus far are promising but many issues must be addressed before neural transplantation can be considered a routine therapeutic option for PD. The future of neural transplantation for the treatment of neurological disorders may rest in the discovery of a suitable alternative cell type for fetal tissue. One such alternative may be neurons derived from a human teratocarcinoma (hNT). hNT neurons have been shown to survive and integrate within the host brain following transplantation and provide functional recovery in animal models of stroke and Huntington's disease. In this study, we describe the transplantation of hNT neurons in the substantia nigra (SN) and striatum of the rat model for PD. Twenty-seven rats were grafted with one of three hNT neuronal products; hNT neurons, hNT-DA neurons, or lithium chloride (LiCl) pretreated hNT-DA neurons. Robust hNT grafts could be seen with anti-neural cell adhesion molecule and anti-neuron-specific enolase immunostaining. Immunostaining for tyrosine hydroxylase (TH) expression revealed no TH-immunoreactive (THir) neurons in any animals with hNT neuronal grafts. THir cells were observed in 43% of animals with hNT-DA neuronal grafts and all animals with LiCl pretreated hNT-DA neuronal grafts (100%). The number of THir neurons in these animals was low and not sufficient to produce significant functional recovery. In summary, this study has demonstrated that hNT neurons survive transplantation and express TH in the striatum and SN. Although hNT neurons are promising as an alternative to fetal tissue and may have potential clinical applications in the future, further improvements in enhancing TH expression are needed.

Abstract
In the present study, several doses of lithium chloride were tested for their ability to induce the expression of tyrosine hydroxylase (TH) in neurons derived from a human teratocarcinoma cell line (hNT) after 5 and 10 days in vitro (DIV). Following immunocytochemical staining for tyrosine hydroxylase, the percentage of TH-positive neurons was determined and morphometric analysis, including mean soma profile area and neuritic length, was performed. hNT neurons responded to lithium treatment in a dose-dependent manner. In 5 DIV, the most effective dose of lithium chloride (1.0 mM) increased the number of TH-positive neurons approximately sixfold. In addition, both TH-positive hNT neuron mean soma profile area and neurite length were significantly larger than controls by 60 and 70%, respectively. Moreover, even after withdrawal of lithium chloride on day 5, the number of TH-positive neurons in 10 DIV cultures remained significantly increased. These data suggest that hNT cells are indeed responsive to lithium exposure and may serve as a continual source of TH-expressing neurons in new therapeutic approaches to degenerative brain disease.

Abstract
Two depressive patients with systemic lupus erythematosus (SLE) and cerebral infarction, while being treated with corticosteroid, are described. In both cases, lithium was remarkably effective and no severe side-effects occurred. These findings suggest that lithium can be a useful antidepressant agent in the treatment of depressive SLE patients.
