This work was planned to assess the effect of the black olive hydroalcoholic extract on bone mineral density and biochemical parameters in ovariectomized rats.<br /> <strong>Materials and Methods:</strong> Ninety 6-month-old female Sprague Dawley rats were randomly assigned into 7 sets: control (received saline); sham-operated control, Ovariectomized (OVX) rats (received saline); 3 groups of black olive-supplemented OVX rats (respectively, receiving 250, 500, and 750 mg/kg body wt black olive extract orally); and estrogen group (receiving 3 mg/kg/day estradiol valerate). Blood samples were collected 2, 4 and 6 months after treatment to measure calcium (Ca), alkaline phosphatase (ALP), and phosphorus (P). Dual-energy X-ray absorptiometry (DEXA) was applied to measure the bone mineral density (BMD). Global, lumbar spine and lower limb BMD was measured.<br /> <strong>Results:</strong> Ca concentration was significantly increased in the group treated with the highest dose of black olive hydroalcoholic compared to the OVX group (p <0.001). In addition, a significant decrease in ALP concentrations in the group treated with the highest dose of black olive hydroalcoholic comparing with the OVX group was observed (p <0.001). The global, tibia, femur and spine BMD in the group treated with the highest dose of black olive hydroalcoholic and estrogen group were significantly increased compared to the OVX group (p <0.05).<br /> <strong>Conclusion:</strong> Black olive hydroalcoholic extract at the dose of 750 mg/kg, prevented bone loss and augmented bone mineral density and could be a possible candidate for the management of osteoporosis.Mashhad University of Medical SciencesAvicenna Journal of Phytomedicine2228-793010620201101The role of resveratrol as a natural modulator in glia activation in experimental models of stroke5575731552910.22038/ajp.2020.15529ENFarzaneh VafaeeNeuroscience Research Center, Mashhad University of Medical Sciences, Mashhad, Iran0000000298213447Hamed GhazaviNeuroscience Research Center, Mashhad University of Medical Sciences, Mashhad, Iran0000-0002-1758-8010Shima ShirzadNeuroscience Research Center, Mashhad University of Medical Sciences, Mashhad, Iran0000-0003-0962-6432Fatemeh ForouzanfarNeuroscience Research Center, Mashhad University of Medical Sciences, Mashhad, Iran0000-0003-0023-6470Sajjad SahabNegahNeuroscience Research Center, Mashhad University of Medical Sciences, Mashhad, IranMona Riyahi RadDepartment of Biology, Mashhad Branch, Islamic Azad University, Mashhad, Iran0000-0003-4053-2610Journal Article20200217<strong>Objective:</strong> Stroke is one of the most important causes of death and disability in modern and developing societies. In a stroke, both the glial cells and neurons develop apoptosis due to decreased cellular access to glucose and oxygen. Resveratrol (3, 5, 4′-trihydroxy-trans-stilbene) as a herbal compound shows neuroprotective and glioprotective effects. This article reviews how resveratrol can alleviate symptoms after stroke to help neurons to survive by modulating some signaling pathways in glia.<br /> <strong>Materials and Methods:</strong> Various databases such as ISI Web of Knowledge, Scopus, Medline, PubMed, and Google Scholar, were searched from 2000 to February 2020 to gather the required articles using appropriate keywords.<br /> <strong>Results:</strong> Resveratrol enhances anti-inflammatory and decreases inflammatory cytokines by affecting the signaling pathways in microglia such as AMP-activated protein kinase (5' adenosine monophosphate-activated protein kinase, AMPK), SIRT1 (sirtuin 1) and SOCS1 (suppressor of cytokine signaling 1). Furthermore, through miR-155 overexpressing in microglia, resveratrol promotes M2 phenotype polarization. Resveratrol also increases AMPK and inhibits GSK-3β (glycogen synthase kinase <em>3</em> beta) activity in astrocytes, which release energy, makes ATP available to neurons and reduces reactive oxygen species (ROS). Besides, resveratrol increases oligodendrocyte survival, which can lead to maintaining post-stroke brain homeostasis.<br /> <strong>Conclusion:</strong> These results suggest that resveratrol can be considered a novel therapeutic agent for the reduction of stroke symptoms that can not only affect neuronal function but also play an important role in reducing neurotoxicity by altering glial activity and signaling.Mashhad University of Medical SciencesAvicenna Journal of Phytomedicine2228-793010620201101Protective impact of Rosa damascena against neural damage in a rat model of pentylenetetrazole (PTZ)-induced seizure5745831562110.22038/ajp.2020.15621ENMansour HomayounSchool of Medicine, Mashhad University of Medical Sciences, Mashhad, IranReyhaneh ShafieyanSchool of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran0000-0003-2557-3895Masoumeh SeghatoleslamDepartment of Anatomy and Cell Biology, School of Medicine, Mashhad University of Medical Sciences, Mashhad, IranSeyed Mahmoud HosseiniSchool of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran0000-0001-6425-5123Alireza Ebrahimzadeh-bideskanDepartment of Anatomy and Cell Biology, School of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran0000-0003-4333-250XJournal Article20190217<strong>Objective:</strong> Based on the previously-declared anticonvulsant properties of <em>Rosa damascena</em> (<em>R. damascena</em>), this study explored the probable effects of <em>R. damascena</em> on neuronal apoptosis in the hippocampus of a rat model of pentylenetetrazole (PTZ)-induced seizure.<br /> <strong>Materials and Methods:</strong> 40 male Wistar rats were randomely divided into control (n=8) and experimental (n=32) groups which underwent PTZ injection. A one-week pre-medication with 50 (PTZ-Ext 50) (n=8), 100 (PTZ-Ext 100) (n=8), and 200 (PTZ-Ext 200) (n=8) mg/kg of hydro-alcoholic extract of <em>R. Damascene </em>was performed while one experimental group (PTZ-induced group) (n=8) received only saline during the week before PTZ injection. After provocation of PTZ-induced seizures, the brains underwent tissue processing and TUNEL staining assay for apoptotic cell quantification.<br /> Results: Our findings revealed that PTZ-induced seizures led to apoptosis in neuronal cells of all sub-regions of the hippocampus; yet, only at CA1, CA3 and DG sub-regions of the PTZ-induced group, the difference in the number of apoptotic neuronal cells was significant in comparison with the control group. In addition, pre-medication with the plant extract led to a significant drop in the quantity of apoptotic neurons in these sub-regions in comparison with the PTZ-induced group which received no pre-medication .<br /> <strong>Conclusion:</strong> The results of this study showed that <em>R. damascena</em> extract exerts neuro-protective effects on PTZ-induced seizure.Mashhad University of Medical SciencesAvicenna Journal of Phytomedicine2228-793010620201101Phytochemical, anti-inflammatory and analgesic properties of stembark extract and fractions of Lonchocarpus sericeus Poir.

The plant was studied for its anti-inflammatory as well as analgesic potency using standard biological models.<br /> <strong>Materials and Methods:</strong> The stembark of <em>L. sericeus </em>was evaluated for anti-inflammatory properties using egg albumin and xylene-induced oedema models. The pain-relieving property was evaluated using acetic acid-induced writhing and thermally-induced pain models. Median lethal dose determination (intraperitoneal LD<sub>50</sub>), quantification of some phytochemicals as well as phytochemical screening were also performed.<br /> <strong>Results:</strong> The LD<sub>50</sub> of stembark extract of <em>L. sericeus </em>was found to be 3,100 mg/kg (i. p). The crude extract and fractions (310-930 mg/kg) effectively reduced oedema caused by egg albumin and xylene and exhibited high analgesic properties in inhibiting pain induced by acetic acid and heat. These reductions were dose-dependent and statistically significant (p <0.05-0.001) when compared to distilled water and similar to prototype drugs employed. Quantitative determinations of some bio-active constituents of the plant showed a higher flavonoid content (0.52±0.02 mg/100 g) compared to alkaloids (0.36±0.02 mg/100 g) and flavonoids (0.49±0.03 mg/100 g). Phytochemical screening of the stembark showed the presence of alkaloids, cardiac glycosides, flavonoids terpenes, tannins and saponins.<br /> <strong>Conclusion:</strong> These results imply that the stembark extract of <em>L. sericeus </em> possesses anti-inflammatory and analgesic potency and these data validate its wide use in folkloric medicine for inflammation and pain management.Mashhad University of Medical SciencesAvicenna Journal of Phytomedicine2228-793010620201101Cytotoxic and apoptogenic effects of Dracocephalum kotschyi Boiss., extracts against human glioblastoma U87 cells5946031562310.22038/ajp.2020.15623ENMahmoud ShaabaniDepartment of Horticulture Science and Agronomy, Science and Research Branch, Islamic Azad University, Tehran, IranSeyed Hadi MousaviMedical Toxicology Research Center, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad 917794-8564, Iran0000-0002-6467-7307Majid AziziDepartment of Medicinal Plants, College of Agriculture, Ferdowsi University of Mashhad, Mashhad, IranAli Ashraf JafariResearch Institute of Forests and Rangelands, Agricultural Research, Education and Extension Organization (AREEO), Tehran, IranJournal Article20190904<strong>Objective:</strong> Glioblastoma multiforme (GBM) is the most aggressive and malignant brain tumor and has a poor prognosis. This study was aimed to investigate the cytotoxic effects of <em>Dracocephalum</em><em> kotschyi</em> Boiss.<strong> (</strong><em>D. kotschyi</em>) extracts in GBM U87 cell line.<br /> <strong>Materials and Methods:</strong> The extracts of <em>D. kotschyi</em> obtained by two different ways of Soxhlet and soaked. The cytotoxic effects of <em>D. kotschyi</em> extracts were measured using MTT assay following treatment for different times of exposure (24, 48, and 72 hr) and at different concentrations of <em>D. kotschyi</em> extracts. The effects of <em>D. kotschyi</em> extracts on cellular oxidative stress were also evaluated by measuring cellular ROS levels. Furthermore, cellular death and apoptosis were studied by sub G1 analysis and Annexin V-FITC/propidium iodide (PI) staining using flow cytometry method, respectively. Characterization of the extracts was carried out using gas chromatography/mass spectrometry (GC/MS) analysis by Agilent GC-MSD system.<br /> <strong>Results:</strong> Our results indicated that<em>D. kotschyi</em> extracts decreased U87 cell viability in a time- and dose-dependent manner. Moreover, treatment with <em>D. kotschyi</em> extracted by Soxhlet for 24 and 48 hr significantly increased the levels of cellular ROS and Sub G1 population (p D. <em>kotschyi</em> mainly consisted of β-caryophellene, α-pinene and limonene.<br /> <strong>Conclusion:</strong> Our findings demonstrated that <em>D. </em><em>kotschyi</em> extracts can exert cytotoxic effects against GBM U87 cell line in a time- and concentration-dependent manner, and these effects may be mediated through intracellular ROS accumulating. However, further studies should be performed to confirm the efficacy and exact mechanism of action of the extracts.Mashhad University of Medical SciencesAvicenna Journal of Phytomedicine2228-793010620201101The Protective Role of Kombucha Extract on Normal Intestinal Microflora,High-Cholesterol DietCaused Hypercholesterolemia,and Histological Structures Changes in New Zealand White Rabbits6046141600810.22038/ajp.2020.16008ENZeyton Alaei1.

Its function is often impressed by changes of the blood flow, hypovolemic shock, transplantation, etc. Maintaining liver function is a major challenge and there are many approaches to potentiate this organ against different stresses. Antioxidants protect organs against oxidative stress. P-coumaric acid (PC) as an oxidant has many beneficial effects. Therefore, PC was used as a pretreatment to test its potential against oxidative stress induced by liver Ischemia-reperfusion injury in rats. <br /> <strong>Materials and Methods:</strong> In order to test the potential hepatoprotective effect of PC against IR injury, five groups of rats were used: Normal (NC; intact group); Sham; p-coumaric acid (PC); IR-CO, and PC-IR. PC, Sham, NC, PC-IR and IR-CO groups that received vehicle or p-coumaric acid at a dose of 100 mg/kg for 7 consecutive days as pretreatment before IR induction. Animals in PC-IR, and IR-CO groups underwent hepatic IR injury. Liver levels of antioxidants were determined and functional liver tests were done. Hematoxylin and eosin staining was done to determine the structural changes of the liver. Gene expression of caspase-3 was also assessed. <br /> <strong>Results:</strong> Hepatic IR injury disrupted liver function by increasing the levels of AST, and ALT, and decreasing GSH, SOD and catalase. PC significantly decreased liver inflammation, reverted liver functional enzymes and antioxidants levels to normal, reduced the gene expression of caspase-3 in PC-IR rats compared to the IR-CO group.<br /> <strong>Conclusion:</strong> These findings revealed that PC through improving liver´s antioxidants, liver functional tests and down-regulating apoptotic gene protein, caspase-3, protects the liver against injury induced by IR.
