چکیده آلکالوئیدهای ?– کربولین نظیر هارمان در مواد غذایی گیاهی معمولی( گندم، برنج، ذرت، جو، انگور و قارچ) و در مواد مشتق شده از گیاهانی نظیر توتون یافت می شوند. این آلکالوئیدها دارای اثرات شناختی زیادی از جمله تغییر در حافظه کوتاه مدت و بلند مدت و اثرات توهم زا می باشند. در این مطالعه نقش سیستم گلوتاماترژیک در هیپوکامپ پشتی بر روی اثرات هارمان بر حافظه اجتنابی مهاری مورد مطالعه قرار گرفته است. ...
Background and Objective: Current and common treatment of toxoplasmosis consist of oral adminstration of pyrimethamine and sulfadiazine. However, this drug combination has substantial toxicity and side effects on patients, especially in immunocompromised individuals. Echinacea purpurea is a medicinal plant with antimicrobial properties which boosts the immune system. This study was carried out ...
Purpose: Determining the effect of progesterone on the embryo quality (total cell number and diameter of blastocyst), survival and implantation rates of mouse blastocyst with or without ovarian stimulation. Materials and Methods: Female 6-10 weeks old NMRI mice were divided into four groups as follows: (a) Non-stimulated pregnant mice as control (b) Non-stimulated pregnant mice with daily inje...
Objective(s): Controversial results have been reported regarding the anti-tumor properties of extracellular vesicles derived from mesenchymal stem cells (MSCs). The present study was conducted to evaluate whether secretome derived from Human Wharton’s jelly mesenchymal stem cells (hWJMSCs) may stimulate or inhibit breast cancer growth in vitro and in vivo.<st...
Background: Melanoma progression and metastasis is suggested to be mediated by increased accumulation of myeloid derived suppressor cells. Various chemotherapeutic drugs such as 5-Fluorouracil in single low concentration have the capacity, at least in part, to reverse tumor progression by reducing myeloid derived suppressor cellsmediated immunosuppression. Objective: To assess whether multiple ...
Background and purpose: There are few treatment options available for treatment of toxoplasmosis and effective drugs have serious toxic effects. In this study, the in vivo and in vitro anti-toxoplasma activities of Heracleum persicum and Foeniculum vulgare fruits essential oils were investigated. Materials and methods: In vitro, Vero cells were incubated with different concentrations of essent...
the antitumor activity of ethanol extract of prosopis glandulosa torr. (epg) was evaluated against ehrlich ascites carcinoma (eac) tumor model in swiss albino mice on dose dependent manner. the activity was assessed using survival time, average increase in body weight, hematological parameters and solid tumor volume. oral administration of epg at the dose of 100, 200 and 400 mg/kg, significantl...

Vicia genus has 45 species in Iran. Many protective and biological activities have been reported from these species. In spite of many works, nothing is known about protective effect of V. cracca against hypoxia conditions. In this study, protective effects of V. cracca extract against hypoxia-induced lethality in mice were evaluated by three experimental models of hypoxia, asphyctic, haem...
Introduction: Mesenchymal stem cells (MSCs) are suitable candidates for the treatment of liver diseases. However, their low survival rate limits their efficacy following transplantation. This study aimed to evaluate the therapeutic potentials of H2O2-preconditioned umbilical cord-derived MSCs (UCMSCs) on acute liver failure (ALF) in mice. Methods: UCMSCs were pre-conditioned with different con...
