  1. Fulltext Therapeutic potential of the haruan (Channa striatus): from food to medicinal uses
    Mohd SM, Abdul Manan MJ
    Malays J Nutr, 2012 Apr;18(1):125-36.
    PMID: 23713236 MyJurnal
    The haruan (Channa striatus) is an indigenous, predatory freshwater fish of Malaysia. It is a common food fish among the local populace with traditionally identified pharmacological benefits in treating wound and pain and in boosting energy of the sick. Channa striatus is also a subject of renewed interest in Malaysian folk medicine in the search for a better cure for diseases and ailments. Amino acids and fatty acids, found in high concentrations in the fish, might have contributed to its pharmacological properties. Important amino acids of the fish include glycine, lysine and arginine, while its fatty acids are arachidonic acid, palmitic acid and docosahexaenoic acid. They appear to effect their influence through the formation of several types of bioactive molecules. Extracts of the fish are produced from whole fish, roe, mucus and skin of the fish. This review updates research findings on potential uses of Channa striatus, beyond the traditional prescription as a wound healer, pain reliever and energy booster to include its properties as a ACE-inhibitor, anti-depressant and neuroregenerative agent. The fish appears to have wide-ranging medical uses and should be studied more intensively to unearth its other properties and mechanisms of action.

    MyJurnal
    Chronic idiopathic facial pain is the diagnosis given to a group of orofacial pain of psychogenic origin which includes atypical facial pain, facial-arthromyalgia, atypical odontalgia and oral dysaesthesia. Despite various biochemical findings, the condition remains poorly understood, but we have begun to understand the nature of these patients. This review discusses the possible aetiology of the disease through various biochemical and clinical findings. The contribution of behavioural and psychological factors to the clinical course of the disease are described. The type of adverse life events that predispose people to the disease and their potency are briefly mentioned. The current diagnostic approach for the disease is also mentioned. Treatment includes antidepressant medication, physiotherapy, bite-guards and analgesics. The problems encountered in the long-term management and outcome studies of these patients include drop-outs, non-compliance and denial.

  3. Fulltext Neuropsychiatric manifestation after a stroke: newly developed symptoms or side-effect of drug?
    Tan EC, Aziz NA, Ahmad S
    BMJ Case Rep, 2012;2012.
    PMID: 22907854 DOI: 10.1136/bcr-2012-006518
    A 55-year-old woman presented with sudden onset of left-sided body weakness and numbness, which was diagnosed as multifocal cerebral infarct with right thalamic bleed. She had concurrent hypertension, diabetes mellitus and chronic kidney disease. She suffered from central poststroke pain and reactive depression as poststroke complications, for which amitriptyline was prescribed. Unfortunately, she developed symptoms suggestive of mania and psychosis upon initiation of medications, which resolved upon withdrawal of amitriptyline. Amitriptyline is effective for treatment of poststroke pain and particularly useful in concomitant depression. Unexpectedly, this patient developed new psychopathologies after initiation of this medication. This case highlights the development of new psychopathologies that could be due to the antidepressant, underlying bipolar disorder or a complication of the stroke itself. Primary care providers need to actively enquire regarding neuropsychiatric symptoms because they can adversely affect the patient's quality of life as well as impede rehabilitation efforts.

  5. Fulltext Potential Nutraceutical Benefits of In Vivo Grown Saffron (Crocus sativus L.) As Analgesic, Anti-inflammatory, Anticoagulant, and Antidepressant in Mice
    Khan A, Muhamad NA, Ismail H, Nasir A, Khalil AAK, Anwar Y, et al.
    Plants (Basel), 2020 Oct 22;9(11).
    PMID: 33105854 DOI: 10.3390/plants9111414
    Crocus sativus, a medicinally important herbaceous plant, has been traditionally used to cure coughs, colds, insomnia, cramps, asthma, and pain. Moreover, the therapeutic applications of saffron include its immunomodulatory and anticancer properties. The current experimental analysis was performed to explore the potential nutraceutical efficacy of corm, leaf, petal, and stigma of saffron ethanolic extracts as analgesic, anti-inflammatory, anticoagulant, and antidepressant using hot plate, carrageenan-induced paw edema, capillary tube and forced swim test, respectively in mice. The results indicated that among all the extracts, stigma ethanolic extract (SEE) represented maximum latency activity (72.85%) and edema inhibition (77.33%) followed by petal ethanolic extract (PEE) with latency activity and edema inhibition of 64.06 and 70.50%, respectively. Corm ethanolic extract (CEE) and leaf ethanolic extract (LEE) displayed mild analgesic activity of 22.40% and 29.07%, respectively. Additionally, LEE (53.29%) and CEE (47.47%) exhibited mild to moderate response against inflammation. The coagulation time of SEE (101.66 s) was almost equivalent to the standard drug, aspirin (101.66 s), suggesting a strong anticoagulant effect followed by PEE (86.5 s). LEE (66.83 s) represented moderate inhibitory effect on coagulation activity while CEE (42.83 s) showed neutral effect. Additionally, PEE and SEE also expressed itself as potential antidepressants with immobility time ≤76.66 s, while CEE (96.50 s) and LEE (106.83 s) indicated moderate to mild antidepressant efficacy. Based on the in vivo activities, saffron extract, particularly SEE and PEE, can be used as a potential nutraceutical and therapeutic agent due to its significant pharmacological activities.

    Neuropsychiatr Dis Treat, 2014;10:1433-8.
    PMID: 25120364 DOI: 10.2147/NDT.S67008
    Adherence to antidepressant treatment is an essential step in the management of patients with major depressive disorder, and several factors can contribute to antidepressant nonadherence. Evidence supports the hypothesis that patient treatment satisfaction will result in improved adherence; therefore, the aim of this study was to investigate the relationship between patient treatment satisfaction and adherence to antidepressants, and the role of patient beliefs toward medication in patient treatment satisfaction.

  7. Hypersexuality As a Neuropsychiatric Disorder: The Neurobiology and Treatment Options
    Asiff M, Sidi H, Masiran R, Kumar J, Das S, Hatta NH, et al.
    Curr Drug Targets, 2018;19(12):1391-1401.
    PMID: 28325146 DOI: 10.2174/1389450118666170321144931
    Hypersexuality refers to abnormally increased or extreme involvement in any sexual activity. It is clinically challenging, presents trans-diagnostically and there is extensive medical literature addressing the nosology, pathogenesis and neuropsychiatric aspects in this clinical syndrome. Classification includes deviant behaviours, diagnosable entities related to impulsivity, and obsessional phenomena. Some clinicians view an increase in sexual desire as 'normal' i.e. psychodynamic theorists consider it as egodefensive at times alleviating unconscious anxiety rooted in intrapsychic conflicts. We highlight hypersexuality as multi-dimensional involving an increase in sexual activity that is associated with distress and functional impairment. The aetiology of hypersexuality is multi-factorial with differential diagnoses that include major psychiatric disorders (e.g. bipolar disorder), adverse effects of treatments (e.g. levodopatreatment), substance-induced disorders (e.g. amphetamine substance use), neuropathological disorders (e.g. frontal lobe syndrome), among others. Numerous neurotransmitters are implicated in its pathogenesis, with dopamine and noradrenaline playing a crucial role in the neural reward pathways and emotionally- regulated limbic system neural circuits. The management of hypersexuality is determined by the principle of de causa effectu evanescent, if the causes are treated, the effect may disappear. We aim to review the role of pharmacological agents causing hypersexuality and centrally acting agents treating the associated underlying medical conditions. Bio-psycho-social determinants are pivotal in embracing the understanding and guiding management of this complex and multi-determined clinical syndrome.

    Depression is a common mental disorder that may lead to major mental health problems, and antidepressant drugs have been used as a treatment of choice to mitigate symptoms of major depressive disorders by ameliorating the chemical imbalances of neurotransmitters in brain. Since abusing antidepressant drugs such as selective serotonin reuptake inhibitors and tricyclic antidepressant drugs can cause severe adverse effects, continuous toxicological monitoring of the parent compounds as well as their metabolites using numerous analytical methods appears pertinent. Among them, capillary electrophoresis has been popularly utilized since the method has a lot of advantages viz. using small amounts of sample and solvents, ease of operation, and rapid analysis. This review paper brings a survey of more than 30 papers on capillary electrophoresis of antidepressant drugs published approximately from 1999 until 2018. It focuses on the reported capillary electrophoresis techniques and their applications and challenges for determining antidepressant drugs and their metabolites. It is organized according to the commonly used capillary zone electrophoresis method, followed by non-aqueous capillary electrophoresis and micellar electrokinetic chromatography, with details on breakthrough findings. Where available, information is given about the background electrolyte used, detector utilized, and sensitivity obtained.

  10. Antidepressant-like effect of mitragynine isolated from Mitragyna speciosa Korth in mice model of depression
    Idayu NF, Hidayat MT, Moklas MA, Sharida F, Raudzah AR, Shamima AR, et al.
    Phytomedicine, 2011 Mar 15;18(5):402-7.
    PMID: 20869223 DOI: 10.1016/j.phymed.2010.08.011
    Mitragyna speciosa Korth. leaves have been used for decades as a traditional medicine to treat diarrhea, diabetes and to improve blood circulation by natives of Malaysia, Thailand and other regions of Southeast Asia. Mitragynine is the major active alkaloid in the plant. To date, the role of mitragynine in psychological disorders such as depression is not scientifically evaluated. Hence, the present investigation evaluates the antidepressant effect of mitragynine in the mouse forced swim test (FST) and tail suspension test (TST), two models predictive of antidepressant activity and the effect of mitragynine towards neuroendocrine system of hypothalamic-pituitary-adrenal (HPA) axis by measuring the corticosterone concentration of mice exposed to FST and TST. An open-field test (OFT) was used to detect any association of immobility in the FST and TST with changes in motor activity of mice treated with mitragynine. In the present study, mitragynine at dose of 10 mg/kg and 30 mg/kg i.p. injected significantly reduced the immobility time of mice in both FST and TST without any significant effect on locomotor activity in OFT. Moreover, mitragynine significantly reduced the released of corticosterone in mice exposed to FST and TST at dose of 10 mg/kg and 30 mg/kg. Overall, the present study clearly demonstrated that mitragynine exerts an antidepressant effect in animal behavioral model of depression (FST and TST) and the effect appears to be mediated by an interaction with neuroendocrine HPA axis systems.

  11. Exploring the potential of tianeptine matrix tablets: Synthesis, physico-chemical characterization and acute toxicity studies
    Salam NA, Naeem MA, Malik NS, Riaz M, Shahiq-Uz-Zaman -, Masood-Ur-Rehman -, et al.
    Pak J Pharm Sci, 2020 Jan;33(1(Supplementary)):269-279.
    PMID: 32122858
    The main objective of the present study was to explore the potential of matrix tablets as extended release dosage form of tianeptine, using HMPC K100 as a polymer. HPMC K100 extended the release of the drug from formulation due to the gel-like structure. Direct compression method was adopted to compress the tablets using different concentrations of polymer. Tablets were evaluated for pre-compression and post-compression parameters. Drug release study showed that tablet extends the release of drug with the increasing concentration of polymer. Drug, polymers and tablets were analyzed and/or characterized for compatibility, degradation, thermal stability, amorphous or crystalline nature via FTIR, DSC, TGA, XRD studies. SEM study predicted that tablets had a uniform structure. HPMC K100 based tablets were similar to that of the reference product. Acute toxicity study conducted on Swiss albino mice showed that matrix tablets were safe and non-toxic, as no changes in physical activity and functions of organs were observed. Biochemical and histopathological study revealed lack of any kind of abnormality in liver and renal function. Moreover, necrotic changes were absent at organ level.

    Khairani Yahya, Azizah Saie
    Malaysian Journal of Psychiatry, 2018;27(1):0-0.
    MyJurnal
    In recent years, more cases of manic switches on Mirtazapine have been reported. In this report, we discuss a case of manic switch in a gentleman who was treated as unipolar depression. A 66-year-old man presented to psychiatry 8 months following a nephrectomy for symptoms of depression. Treatment with Sertraline 50mg daily was initiated and titrated to 150mg, along with Zolpidem and Clonazepam to aid his sleep. Despite these medications he never achieved remission and continued to have persistent anxiety and insomnia. Due to suboptimal control, treatment was changed to Mirtazapine 15mg daily. At day 20 he showed symptoms of mania which included talkativeness, increased goal directed activities, reduced need for sleep and socially disinhibited behavior. Mirtazapine was discontinued, and treatment was changed to Sodium Valproate, optimized to 1000mg daily, augmented with Quetiapine 150mg daily. Remission was achieved after 4 months and he has remained asymptomatic for 2 months. This was his first episode of mania, and a diagnosis of Bipolar I disorder was made. In conclusion, antidepressant induced manic switches are common, they are relatively under-appreciated and under-reported, especially with the use of sleep-promoting antidepressants. All antidepressants should be considered to be a potential mediator of a switch in view of its pharmacological properties.

  14. The effect of nitrazepam on depression and curiosity in behavioral tests in mice: The role of potassium channels
    Nikoui V, Ostadhadi S, Azhand P, Zolfaghari S, Amiri S, Foroohandeh M, et al.
    Eur J Pharmacol, 2016 Nov 15;791:369-376.
    PMID: 27615446 DOI: 10.1016/j.ejphar.2016.09.017
    Evidence show that gamma-aminobutyric acid (GABA) receptors are involved in depression, so the aim of this study was to investigate the effect of nitrazepam as agonist of GABAA receptors on depression and curiosity in male mice and the role of potassium channel in antidepressant-like response. For this purpose, we studied the antidepressant-like properties of fluoxetine, nitrazepam, glibenclamide, and cromakalim by both forced swimming test (FST) and tail suspension test (TST). Animals were injected by various doses of nitrazepam (0.05, 0.1, and 0.5mg/kg). Nitrazepam at dose of 0.5mg/kg significantly decreased the immobility time compared to control group in both FST and TST. Fluoxetine also showed such a response. Co-administration of nitrazepam (0.05mg/kg) with glibenclamide in TST (1mg/kg) and in FST (0.3, 1mg/kg) also showed antidepressant-like response. Beside, cromakalim (0.1mg/kg) could reverse the antidepressant-like effect of nitrazepam (0.5mg/kg) in both FST and TST, while cromakalim and glibenclamide alone could not change the immobility time compared to control group (P>0.05). The hole-board test revealed that nitrazepam at doses of 0.5 and 0.1mg/kg could increase the activity of the animal's head-dipping and boost the curiosity and exploration behavior of mice. The results of this study revealed that nitrazepam may possess antidepressant-like properties and this effect is dependent to potassium channels in both FST and TST.

  15. Fulltext Involvement of monoaminergic system in the antidepressant-like effect of aqueous extract of Channa striatus in mice
    Saleem AM, Taufik Hidayat M, Jais AM, Fakurazi S, Moklas MA, Sulaiman MR, et al.
    Eur Rev Med Pharmacol Sci, 2013;17(15):2019-22.
    PMID: 23884821
    BACKGROUND: In our previous study, the aqueous extract of Channa striatus (family: Channidae) fillet (AECSF) showed an antidepressant-like effect in mice. However, the mechanism of the antidepressant-like effect is unknown.
    AIM: The objective of this study was to explore the involvement of monoamines in the antidepressant-like effect of AECSF in mice.
    MATERIALS AND METHODS: AECSF was prepared by steaming the fillets of C. striatus. The male ICR mice were pretreated with various monoaminergic antagonists viz., p-chlorophenylalanine (100 mg/kg, i.p.), prazosin (1 mg/kg, i.p.) and yohimbine (1 mg/kg, i.p.), SCH23390 (0.05 mg/kg, s.c.) and sulpiride (50 mg/kg, i.p.) followed by treatment with AECSF and tested in tail suspension test (TST). Two-way ANOVA with Tukey test were used at p < 0.05 for significance.
    RESULTS: The pretreatments with p-chlorophenylalanine, prazosin and yohimbine, but not with SCH23390 and sulpiride, were able to reverse the antidepressant-like effect of AECSF in TST.
    CONCLUSIONS: The antidepressant-like effect of AECSF may be mediated through the serotonergic and noradrenergic systems and not through the dopaminergic system.

    Postpartum depression affects 15% of women. Channa striatus, a freshwater fish, is consumed in local Malay population as a rejuvenating diet during postpartum period. This study evaluated the antidepressant-like effect of lipid extract of C. striatus fillet and its mechanism of action in female Sprague-Dawley rats in postpartum model of depression. The rats were ovariectomized and treated with high dose of progesterone and estradiol benzoate for 23 days to have hormone-simulated pregnancy. The day 24 and afterwards were considered as the postpartum period. During the postpartum period, lipid extract was administered at 125, 250, and 500 mg/kg through intraperitoneal route for 15 days. Fluoxetine (10 mg/kg) was used as the positive control. On postpartum day 15, the animals were tested in forced swimming test (FST) and open field test (OFT) followed by biochemical analysis. Withdrawal of hormone administration during the postpartum period induced depressive-like behavior in FST. Administration of lipid extract reversed that depressive-like behavior at 125, 250, and 500 mg/kg in FST. In OFT, it decreased the exploratory activity. The mechanism of the antidepressant-like effect may be mediated through the decrease in plasma corticosterone, increase in plasma oxytocin, and decrease in nuclear factor-kappa B in prefrontal cortex of rats.

    Standard psychiatric criteria for depression developed in the United States and United Kingdom are increasingly used worldwide to establish the prevalence of clinical disorders and to help develop services. However, these approaches are rarely sensitive to local and cultural expressions of symptoms or beliefs about treatment. Mismatch between diagnostic criteria and local understanding may result in underreporting of depression and underutilization of services. Little such research has been conducted in Malaysia, despite the acknowledged high rate of depression and low access to services. This study examines depression in Moslem Malay women living in Johor Bahru, Southern Peninsular Malaysia, to explore depression symptoms using the Structured Clinical Interview for DSM-IV. The 61 women interviewed were selected on the basis of high General Health Questionnaire scores from a large questionnaire survey of 1,002 mothers. The illustrative analysis looks at descriptions of depressed mood, self-depreciation and suicidal ideation, as well as attitudes toward service use. The women gave full and open descriptions of their emotional symptoms, easily recognizable by standard symptom categories, although somatic symptoms were commonly included, and the spiritual context to understanding depression was also prevalent. However, few women had knowledge about treatment or sought medical services, although some sought help from local spiritual healers. Attending to such views of depression can help develop services in Malaysia.

    ETHNOPHARMACOLOGICAL RELEVANCE: Aglaonema hookerianum Schott is an ethnomedicinally important plant used to treat a variety of diseases, including sexual and depression-like disorders. However, the scientific basis underlying the aforesaid properties have not been well justified.

    AIM OF THE STUDY: The present investigation aimed to investigate the anxiolytic, antidepressant and aphrodisiac potentials of methanol leaves extract of A. hookerianum (MEAH) in Swiss albino mice.

    MATERIALS & METHODS: Swiss albino mice (20-30 g) were orally administrated with MEAH at the doses ranging from 100 to 400 mg/kg, b.w. The elevated plus maze (EPM) and hole board test (HBT) were performed to determine the anxiolytic activity and the forced swimming test (FST) and tail suspension test (TST) were performed to determine the antidepressant activity of MEAH. Besides, the aphrodisiac activity of MEAH was conducted through the mounting behaviour and orientation behaviour analysis. Diazepam (1 mg/kg, b.w., i.p.) for EPM and HBT; fluoxetine HCl (20 mg/kg, b.w., p.o.) for FST and TST, and sildenafil (5 mg/kg, b.w., p.o.) for the mounting behaviour analysis and orientation behaviour analysis were used as reference drugs.

    RESULTS: The administration of the MEAH produced a strong (p

  20. Pathophysiology of depression: role of sleep and the melatonergic system
    Srinivasan V, Pandi-Perumal SR, Trakht I, Spence DW, Hardeland R, Poeggeler B, et al.
    Psychiatry Res, 2009 Feb 28;165(3):201-14.

    Profound disturbances in sleep architecture occur in major depressive disorders (MDD) and in bipolar affective disorders. Reduction in slow wave sleep, decreased latency of rapid eye movement (REM) sleep and abnormalities in the timing of REM/non-REM sleep cycles have all been documented in patients with MDD. It is thus evident that an understanding of the basic mechanisms of sleep regulation is essential for an analysis of the pathophysiology of depressive disorders. The suprachiasmatic nucleus (SCN), which functions as the body's master circadian clock, plays a major role in the regulation of the sleep/wakefulness rhythm and interacts actively with the homeostatic processes that regulate sleep. The control of melatonin secretion by the SCN, the occurrence of high concentrations of melatonin receptors in the SCN, and the suppression of electrical activity in the SCN by melatonin all underscore the major influence which this neurohormone has in regulating the sleep/wake cycle. The transition from wakefulness to high sleep propensity is associated with the nocturnal rise of endogenous melatonin secretion. Various lines of evidence show that depressed patients exhibit disturbances in both the amplitude and shape of the melatonin secretion rhythm and that melatonin can improve the quality of sleep in these patients. The choice of a suitable antidepressant that improves sleep quality is thus important while treating a depressive disorder. The novel antidepressant agomelatine, which combines the properties of a 5-HT(2C) antagonist and a melatonergic MT(1)/MT(2) receptor agonist, has been found very effective for resetting the disturbed sleep/wake cycle and in improving the clinical status of MDD. Agomelatine has also been found useful in treating sleep problems and improving the clinical status of patients suffering from seasonal affective disorder.
