Effect of Harmine on Nicotine‑Induced Kidney Dysfunction in Male Mice [Downloaded free from http://www.ijpvmjournal.net on Tuesday, June 25, 2019, IP: 94.199.136.196] Original Article Effect of Harmine on Nicotine‑Induced Kidney Dysfunction in Male Mice Abstract Mohammad Reza Background: The nicotine content of cigarettes plays a key role in the pathogenesis of kidney Salahshoor, disease. Harmine is a harmal‑derived alkaloid with antioxidant properties. This study was Shiva Roshankhah, designed to evaluate the effects of harmine against nicotine‑induced damage to the kidneys of mice. Methods: In this study, 64 male mice were randomly assigned to eight groups: saline and Vahid Motavalian, nicotine‑treated groups (2.5 mg/kg), harmine groups (5, 10, and 15 mg/kg), and nicotine (2.5 mg/ Cyrus Jalili kg) + harmine‑treated groups (5, 10, and 15 mg/kg). Treatments were administered intraperitoneally Department of Anatomical daily for 28 days. The weights of the mice and their kidneys, kidney index, glomeruli characteristics, Sciences, Medical School, thiobarbituric acid reactive species, antioxidant capacity, kidney function indicators, and serum Kermanshah University of nitrite oxide levels were investigated. Results: Nicotine administration significantly improved kidney Medical Sciences, Daneshgah Ave., Taghbostan, malondialdehyde (MDA) level, blood urea nitrogen (BUN), creatinine, and nitrite oxide levels and Kermanshah, Iran decreased glomeruli number and tissue ferric reducing/antioxidant power (FRAP) level compared to the saline group (P < 0.05). The harmine and harmine + nicotine treatments at all doses significantly reduced BUN, kidney MDA level, creatinine, glomerular diameter, and nitrite oxide levels and increased the glomeruli number and tissue FRAP level compared to the nicotine group (P < 0.05). Conclusions: It seems that harmine administration improved kidney injury induced by nicotine in mice.

Evidence has pointed to the β-carboline harmine as a potential therapeutic target for the treatment of depression. The present study we evaluated the effects of acute and chronic administration of harmine (5, 10 and 15 mg/kg) and imipramine (10, 20 and 30 mg/kg) or saline in lipid and protein oxidation levels and superoxide dismutase (SOD) and catalase (CAT) activities in rat prefrontal cortex and hippocampus. Acute and chronic treatments with imipramine and harmine reduced lipid and protein oxidation, compared to control group in prefrontal cortex and hippocampus. The SOD and CAT activities increased with acute and chronic treatments with imipramine and harmine, compared to control group in prefrontal cortex and hippocampus.

Materials and method: The alkaloids harmine and harmaline have been isolated from a methanolic extract from the seeds of P. harmala L. and have been characterized by spectroscopic-Mass and NMR methods. The cytotoxicity of the methanolic extract and both alkaloids has been investigated in the three human cancer cell lines UACC-62 (melanoma), TK- 10 (renal) and MCF-7 (breast) and then compared to the positive control effect of the etoposide. Results and conclusion: The methanolic extract and both alkaloids have inhibited the growth of these three cancer cell-lines and we have discussed possible mechanisms involved in their cytotoxicity.

  • A Review of Serotonin Toxicity Data: Implications for the Mechanisms of Antidepressant Drug Action P
    ARTICLE IN PRESS REVIEW A Review of Serotonin Toxicity Data: Implications for the Mechanisms of Antidepressant Drug Action P. Ken Gillman Data now exist from which an accurate definition for serotonin toxicity (ST), or serotonin syndrome, has been developed; this has also lead to precise, validated decision rules for diagnosis. The spectrum concept formulates ST as a continuum of serotonergic effects, mediated by the degree of elevation of intrasynaptic serotonin. This progresses from side effects through to toxicity; the concept emphasizes that it is a form of poisoning, not an idiosyncratic reaction. Observations of the degree of ST precipitated by overdoses of different classes of drugs can elucidate mechanisms and potency of drug actions. There is now sufficient pharmacological data on some drugs to enable a prediction of which ones will be at risk of precipitating ST, either by themselves or in combinations with other drugs. This indicates that some antidepressant drugs, presently thought to have serotonergic effects in animals, do not exhibit such effects in humans. Mirtazapine is unable to precipitate serotonin toxicity in overdose or to cause serotonin toxicity when mixed with monoamine oxidase inhibitors, and moclobemide is unable to precipitate serotonin toxicity in overdose. Tricyclic antidepressants (other than clomipramine and imipramine) do not precipitate serotonin toxicity and might not elevate serotonin or have a dual action, as has been assumed. Key Words: Serotonin toxicity, monoamine oxidase inhibitors, se- do not, and cannot, cause ST (Gillman 2003c; Isbister and Whyte lective serotonin reuptake inhibitors, tricyclic antidepressants, mir- 2003). Such erroneous reports are still being published in tazapine, moclobemide prominent journals (Haddow et al 2004) and continue to main- tain the confused and inaccurate understanding of this toxidrome (Gillman 2005b; Isbister and Buckley 2005).

  • Effects of 3,4-Methylenedioxymethamphetamine (MDMA, Decstasyt) and Para-Methoxyamphetamine on Striatal 5-HT When Co-Administered with Moclobemide
    Brain Research 1041 (2005) 48–55 www.elsevier.com/locate/brainres Research report Effects of 3,4-methylenedioxymethamphetamine (MDMA, dEcstasyT) and para-methoxyamphetamine on striatal 5-HT when co-administered with moclobemide Alexander Freezer, Abdallah SalemT, Rodney J Irvine Department of Clinical and Experimental Pharmacology, Medical School North, University of Adelaide, Adelaide, South Australia 5005, Australia Accepted 27 January 2005 Available online 5 March 2005 Abstract 3,4-Methylenedioxymethamphetamine (MDMA, becstasyQ) and para-methoxyamphetamine (PMA) are commonly used recreational drugs. PMA, often mistaken for MDMA, is reported to be more toxic in human use than MDMA. Both of these drugs have been shown to facilitate the release and prevent the reuptake of 5-hydroxytryptamine (5-HT, serotonin). PMA is also a potent inhibitor of monoamine oxidase type A (MAO-A), an enzyme responsible for the catabolism of 5-HT, and this characteristic may contribute to its increased toxicity. In humans, co-administration of MDMA with the reversible MAO-A inhibitor moclobemide has led to increased apparent toxicity with ensuing fatalities. In the present study, using microdialysis, we examined the effects of co-administration of MDMA and PMA with moclobemide on extracellular concentrations of 5-HT and 5-hydroxy indol acetic acid (5-HIAA) in the striatum of the rat. 5-HT-mediated effects on body temperature and behavior were also recorded. Rats were pretreated with saline or 20 mg/kg (i.p.) moclobemide and 60 min later injected with 10 mg/kg MDMA, PMA, or saline. Dialysate samples were collected every 30 min for 5 h and analyzed by HPLC-ED.

These alkaloids induce in a dose- dependent manner the relaxation in the aorta precontracted with noradrenaline or KCl. However, the removal of endothelium or pre-treatment of intact aortic ring with L-NAME (inhibitor of NOSe synthetase) or with indomethacin (non-specific inhibitor of cyclo-oxygenase), reduces significantly the vasorelaxant response of harmaline but not harmine. According to their IC50 values, prazosin (inhibitor of ␣-adrenorecepteors) reduces the vasorelaxant effect only of harmaline, whereas, pre-treatment with IBMX (non-specific inhibitor of phosphodiesterase) affects both the harmaline and harmine-responses. Inhibitions of L-type voltage-dependent Ca2+ channels (VOCs) in endothelium-intact aortic rings with diltiazem depress the relaxation evoked by harmaline as well as by harmine. Pre-treatment with harmaline or harmine (3, 10 or 30 ␮M) shifted the phenylephrine-induced dose response curves to the right and the maximum response was attenuated indicating that the antagonist effect of both alkaloids on ␣1-adrenorecepteors was non-competitive.
