- چکیده:
- چکیده انگلیسی: The metabolic syndrome, a cluster of metabolic disorders, includes abdominal obesity, hypertension, dyslipidemia, and hyperglycemia leading to insulin resistance, development of diabetes mellitus, and cardiovascular diseases. For the treatment of metabolic syndrome, traditional herbal medicines such as frankincense or Boswellia species have been used due to their anti-inflammatory, anti-oxidant, anti-obesity, antidiabetic, antihypertensive, and hypolipidemic properties. Based on the literature, published evidence up to 2020 about the therapeutic effects of Boswellia species on the metabolic disorder among Medline, Scopus, and Google Scholar were precisely evaluated by keywords such as obesity, diabetes, hyperglycemia, hypertension, blood pressure, dyslipidemia, metabolic syndrome, frankincense, and Boswellia. According to the results, Boswellia species have beneficial effects to control metabolic syndrome and its related disorders such as hyperglycemia, dyslipidemia, hypertension, obesity, diabetes, and its complications. Boswellia species by reducing the resistance to insulin and restoring pancreatic beta cells decrease blood glucose. Also, Boswellia species has antithrombotic and anticoagulant properties that regulate blood pressure. The anti-oxidant properties of Boswellia species modulate the blood lipid profile via reducing TNF-α, IL-1β levels, and increasing the adiponectin level. The therapeutic and protective effects of Boswellia species on metabolic disorders were remarkably confirmed regarding decreasing hyperglycemia, hyperlipidemia, hypertension, and obesity.

- چکیده:
- چکیده انگلیسی: Objective(s): Thymoquinone (TQ) has valuable medical properties like anticancer effects. Development of multidrug resistance (MDR) phenotype is one of the most important factors in failure of cancer chemotherapy. The aim of this study was to evaluate the mode of interaction of TQ and MDR1, a major MDR-related protein in gastric cancer drug resistant EPG85-257RDB cells, and its parental non-resistant EPG85-257 cells.
Materials and Methods: MTT assay was used to assess the effects of TQ and doxorubicin (DOX) on cell viability of tested cell lines and TQ effect on pump performance. HPLC analyses were used to measure the input and output of TQ in EPG85-257RDB cells. Molecular docking studies were used to identify interactions between TQ and MDR1.
Results: TQ inhibited cell viability in a time and concentration-dependent manner. Co-treatment of the cells with TQ and DOX did not significantly affect the amount of cell viability in comparison with DOX treatment alone. The HPLC analyses showed that more than 90% of TQ entered to EPG85-257RDB during 1 hr of treatment with TQ, but it was unable to exit from the cells. Moreover, there was no difference between influx and efflux amount of TQ in cells with inhibited and non-inhibited MDR1 transporters. Molecular docking studies revealed that TQ had a higher inhibitory constant to bind to active site of MDR1 protein as compared to specific inhibitor (verapamil) and substrate (vinblastine) of this transporter.
Conclusion: These results proposed that TQ does not work as an inhibitor or a substrate of MDR1 transporter.- انتشار مقاله: 02-09-1398

- چکیده:
- چکیده انگلیسی: Objective(s): Hyperglycemia induces cellular senescence in various body cells, such as vascular endothelial cells. Since the vessels are highly distributed in the body and nourish all tissues, vascular damages cause diabetes complications such as kidney failure and visual impairment. Alpha-mangostin is a xanthone found in mangosteen fruit with protective effects in metabolic syndrome and diabetes. This paper has investigated the protective effect of this xanthone against high glucose-induced memory senescence in human vascular endothelial cells (HUVECs) in the presence of metformin, as a positive control.
Materials and Methods: To induce the memory senescence model, HUVECs, after three days incubation with high glucose, were incubated with normal glucose for another three days, and for whole six days, cells were treated with metformin (50 µM) or alpha-mangostin (1.25 µM). On the last day, cell viability by MTT assay, oxidative stress by fluorimetric assay, the number of senescent cells by SA beta-galactosidase staining kit, and secretory interleukin-6 by ELISA kit were measured. SIRT1 and P53 proteins were also evaluated by Western blotting.
Results: Metformin and alpha-mangostin significantly increased cell viability, decreased reactive oxygen species, and senescence-associated beta-galactosidase in HUVECs incubated in metabolic memory condition. Generally, metabolic memory increased p53 and acetyl-P53 and decreased SIRT1 proteins in HUVECs, which were reversed by alpha-mangostin and metformin.
Conclusion: These data exhibit that alpha-mangostin, comparable to metformin, protects endothelial cells against metabolic memory-induced senescence, which is likely via SIRT1.- انتشار مقاله: 04-03-1398

- کلمات کلیدی: Crocin Crocus sativus L. Bisphenol A Anti,oxidant AMPA NMDA
- چکیده:
- چکیده انگلیسی: Objective(s): Bisphenol A (BPA), a xenoestrogenic endocrine disrupting agent, is widely used in the production of polycarbonate plastics and has potential adverse effects on the developing nervous system, memory and learning abilities. The protective effect of the crocin, an important active constituent in Crocus sativus L, on memory impairment induced by BPA in rat was determined through evaluation of oxidative stress and the level of NMDA (N-methyl-D-aspartate receptors) and AMPA (α-amino-3-hydroxy-5-methyl-4-isoxazole-propionicd acid) receptors.
Materials and Methods: Rats were orally treated with BPA (100 mg/kg) or sesame seed oil in control group for 28 days. Crocin (10, 20, and 40 mg/kg, IP) was administrated in BPA-orally treated groups for 28 days. Memory and learning functions were evaluated by Morris water maze. The level of malondialdehyde (MDA) and glutathione (GSH) contents were determined in rat hippocampus. Additionally, the expression of NMDA and AMPA receptors were analyzed using Western blot method.
Results: Administration of BPA significantly reduced memory and learning functions. Crocin significantly protected against learning and memory impairments induced by BPA. BPA administration markedly reduced GSH content and induced lipid peroxidation, while crocin was able to increase GSH content in rat hippocampus. The expression of NMDA receptor did not change in BPA-treated rats, while the significant reduction in AMPA receptor expression was observed. Moreover, crocin (20 mg/kg) significantly elevated the expression of AMPA receptor.
Conclusion: Crocin recovered spatial learning and memory defects induced by BPA in part through anti-oxidant activity and modulation the expression of AMPA receptor in rat hippocampus.- انتشار مقاله: 23-03-1398

- چکیده:
- چکیده انگلیسی: Rosemary (Rosmarinus officinalis L.) is an evergreen bushy shrub which grows along the Mediterranean Sea, and sub-Himalayan areas. In folk medicine, it has been used as an antispasmodic, mild analgesic, to cure intercostal neuralgia, headaches, migraine, insomnia emotional upset, and depression. Different investigations have highlighted rosemary neuropharmacological properties as their main topics. Rosemary has significant antimicrobial, anti-inflammatory, anti-oxidant, anti-apoptotic, anti-tumorigenic, antinociceptive, and neuroprotective properties. Furthermore, it shows important clinical effects on mood, learning, memory, pain, anxiety, and sleep. The aim of the current work is to review the potential neuropharmacological effects of different rosemary extracts and its active constituents on nervous system disorders, their relevant mechanisms and its preclinical application to recall the therapeutic potential of this herb and more directions of future research projects. The data were gathered by searching the English articles in PubMed, Scopus, Google Scholar, and Web of Science. The keywords used as search terms were ‘Rosmarinus officinalis’, ‘rosemary’, ‘nervous system’, ‘depression’, ‘memory’, ‘Alzheimer’s disease’ ‘epilepsy’, ‘addiction’, ‘neuropathic pain’, and ‘disorders’. All kinds of related articles, abstracts and books were included. No time limitation was considered. Both in vitro and in vivo studies were subjected to this investigation. This review authenticates that rosemary has appeared as a worthy source for curing inflammation, analgesic, anti-anxiety, and memory boosting. It also arranges new perception for further investigations on isolated constituents, especially carnosic acid, rosmarinic acid, and essential oil to find exquisite therapeutics and support drug discovery with fewer side effects to help people suffering from nervous system disorders.

- چکیده:
- چکیده انگلیسی: Objective(s): Ethanol withdrawal following chronic use, is an important challenge clinically. In this study, the effect of clavulanic acid was evaluated on the symptoms of ethanol withdrawal in rats.
Materials and Methods: Alcohol dependence was induced by the gavage of ethanol (10% v/v, 2 g/kg), twice daily for 10 days. Clavulanic acid (10, 20, 40, and 80 mg/kg) was administered concurrently with ethanol (sub-acute study), or a single dose after ethanol withdrawal (acute study). Six hours after the last dose of ethanol, anxiety was assessed by the elevated plus-maze (EPM). Seizure-like behavior was evaluated by a sub-convulsive dose of pentylenetetrazol (PTZ, 25 mg/kg/IP). Locomotor activity and motor coordination were measured by the open field and rotarod tests, respectively. Lipid peroxidation marker and antioxidant content were assessed through measuring malondialdehyde (MDA) and glutathione (GSH), respectively.
Results: The number of entries and time spent on the open arms of EPM decreased during the withdrawal state. Motor coordination and locomotor activity were significantly decreased. In the sub-acute study, clavulanic acid 80 mg/kg increased time spent and the number of entries to the open arms of EPM, in withdrawn animals. Both motor incoordination and locomotor activity reduction were normalized by clavulanic acid (10, 20, 40 and 80 mg/kg). Withdrawal-induced PTZ kindling seizure was also suppressed by all of the doses. MDA increased, while GSH decreased after withdrawal. Clavulanic acid attenuated such changes.
Conclusion: Clavulanic acid could prevent the development of alcohol withdrawal-induced anxiety and seizure. Alcohol withdrawal causes oxidative stress which can be prevented by clavulanic acid.- انتشار مقاله: 26-12-1397

- چکیده:
- چکیده انگلیسی: Metabolic syndrome (MetS) is a clustering of several cardiovascular risk factors that include: obesity, dyslipidemia, hypertension and high blood glucose, and often requires multidrug pharmacological interventions. The management of MetS therefore requires high healthcare cost, and can result in poor drug treatment compliance. Hence drug therapies that have pleiotropic beneficial effects may be of value. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are the newest anti-diabetic drugs that mimic incretin effects in the body. They appear to be safe and well tolerable. Herein, the pharmacology of GLP-1RAs, their side effects, drug interactions and their effects in MetS is assessed. We conducted a Google Scholar, PubMed, Scopus, and Web of Science search since 2010 to identify publications related to the use of GLP-1RAs in treating component features of the MetS. Keywords used for the search were: GLP-1 receptor agonist, exenatide, liraglutide, lixisenatide, albiglutide, dulaglutide, MetS, obesity, triglyceride, cholesterol, lipid, hypercholesterolemia hyperlipidemia, atherosclerosis, hypertension, blood pressure, hyperglycemia, hypoglycemia and blood glucose. According to the gathered data, GLP-1RAs appear safe and well tolerated. Pre-clinical and clinical studies have evaluated the lipid-lowering, anti-atherosclerotic, anti-hypertensive and anti-diabetic effects of this class of drugs. Some these effects are related to a reduction in food-seeking behavior, an increase in atrial natriuretic peptide level and hence vascular relaxation and natriuresis, and an increase of pancreas β-cell mass and protection against glucotoxicity. Collectively, this review indicates that there may be some value in GLP-1RAs repositioning to manage MetS risk factors beyond their anti-diabetic effects.

- کلمات کلیدی: oxidative stress,Endothelial dysfunction,Malondialdehyde,Crocin,Nitrate tolerance
- چکیده:
- چکیده انگلیسی: Objective(s): One of the most important problems of taking nitroglycerin is the nitrate tolerance phenomenon and endothelial dysfunction. Oxidative stress is a high-emphasized one of tolerance mechanisms. The possible effect of crocin, one of the anti-oxidant ingredients of saffron, on the nitrate tolerance model was investigated.
Materials and Methods: In the present study, lipid peroxidation and the level of activated and deactivated forms of eNOS were measured. Animals were administered subcutaneously with 25 mg/kg of nitroglycerin, twice a day for 3 days to induce nitrate tolerance model. For evaluation of crocin effects, 20, 40 and 80 mg/kg/day of this compound were injected intraperitoneally in concomitant with nitroglycerin. In the isolated aorta test, after preparation of aorta rings, different concentrations of acetylcholine, sodium nitroprusside and nitroglycerin were added to the organ bath after inducing contraction by phenylephrine and the responsiveness of tissues was recorded.
Results: Findings showed that nitroglycerin administration caused a remarkable overproduction of malondialdehyde (MDA) in the cells and crocin treatment significantly decreased the MDA level. In the nitrate tolerance group, the level of activated eNOS decreased and the level of deactivated eNOS increased. Crocin partly alleviated these changes: however, its effects were not remarkable. Nitroglycerin injection for 3 days developed tolerance to nitroglycerin and cross-tolerance to acetylcholine (endothelial dysfunction) and sodium nitroprusside. Crocin failed to influence significantly on the nitrate tolerance.
Conclusion: Crocin effectiveness is possibly time-dependent; therefore, increasing the duration of treatment with crocin may lead to a significant prevention of nitrate tolerance and endothelial dysfunction.- انتشار مقاله: 25-01-1398
