The present study aims to investigate the effects of mood stabilizers, lithium (Li) and valproate (VPA), on acetylcholinesterase (AChE) activity in the brains of rats subjected to an animal model of mania induced by d-amphetamine (d-AMPH). In the reversal treatment, Wistar rats were first given d-AMPH or saline (Sal) for 14 days. Between days 8 and 14, the rats were treated with Li, VPA, or Sal. In the prevention treatment, rats were pretreated with Li, VPA, or Sal. AChE activity was measured in the brain structures (prefrontal cortex, hippocampus, and striatum). Li, alone in reversion and prevention treatments, increased AChE activity in the brains of rats. VPA, alone in prevention treatment, increased AChE activity in all brain regions evaluated; in the reversion, only in the prefrontal. However, d-AMPH decreased activity of AChE in the striatum of rats in both the reversion and prevention treatments. VPA was able to revert and prevent this AChE activity alteration in the rat striatum. Our findings further support the notion that the mechanisms of mood stabilizers also involve changes in AChE activity, thus reinforcing the need for more studies to better characterize the role of acetylcholine in bipolar disorder. 相似文献

The aim of the present study was to reevaluate the feasibility of diagnosing a mixed features behind bipolar mania and to elucidate the clinical characteristics, treatment response, and course of the illness throughout a 12-month follow-up. The subjects (n=171) were inpatients diagnosed with bipolar I disorder, manic, between 2003 and 2010 and were classified into three groups: “mania” (n=67), “mania with probable mixed features” (n=79), and “mania with definite mixed features” (n=25). Diagnoses were in accordance with the Cincinnati criteria, which include the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision characteristics for a major depressive episode, except for agitation and insomnia. The charts of subjects were retrospectively reviewed for demographic and clinical characteristics prior to the index episode, clinical data regarding the index episode, and treatment courses over a 12-month follow-up period. Subjects in the mania with definite mixed features were more likely to be young at admission, to be female, to have a familial affective loading, and to have a history of suicidality relative to the mania. The results of the present study suggest the need for regular assessment of symptoms associated with both polarities during an episode in routine practice. 相似文献

目的观察奥卡西平治疗复发性躁狂的临床疗效和副反应。方法随机对96例复发性躁狂发作的患者分别以奥卡西平及碳酸锂治疗,使用Bech-Rafaelson躁狂量表(BRMS)评定临床疗效,并对治疗期间出现的药物副反应进行比较。结果两组治疗后BRMS分值均大幅度下降,差异有显著性(P〈0.01),但组间比较差异无显著性(P〉0.05),奥卡西平副反应发生率较低。结论奥卡西平用于治疗复发性躁狂,疗效肯定,与碳酸锂疗效相近,且副反应较轻,安全性好。 相似文献
