    Atherosclerosis is a progressive inflammatory disease and is considered as main reason of death and morbidity in worldwide. The common drugs which are used for treatment of atherosclerosis reveal side effects, therefore it is necessary to identify the natural sources. This study overviews the pathophysiology of atherosclerosis and effective medicinal plants present in Iran. In this study, 19 medical plants have been reported to be scientifically effective against atherosclerosis which are included Punica granatum L., Aloe vera, Amaranthus caudatus L., Artemisia sieberi Besser, Artemisia spp., Rhus coriaria, Nigella sativa L., Trifolium pratense L., Anethum graveolens, Glycyrrhiza glabra, Vaccinium myrtillus L, Gundelia tournefortii L, Hypericum perforatum, Curcuma longa, Crocus sativus L, Malus domestica, Silybum marianum, Berberis integerrima and Portulaca oleracea L. These plants have antioxidant and flavonoid compounds with unknown mechanisms serve to improve atherosclerosis. It seems that medicinal plants native to Iran, which have antioxidant and inhibit the oxidative stress, reduce inflammatory processes and ultimately improve atherosclerosis

    Introduction: Soybean possesses isoflavones and might, therefore, cause problem in thyroid hormone synthesis. The purpose of this study was to study the effect of soybean on serum levels of Thyroid stimulating hormone (TSH), Triiodothyronine (T3), and Thyroxine (T4) in male mice. Methods: In this experimental study, 24 Balb/C male mice were randomly assigned to three groups of eight including control or base diet-fed group and treatment groups 1 and 2 receiving respectively 30 and 50 soybean-containing diet. After nine weeks, the blood sample was taken from the animals&rsquo; heart and serum levels of TSH, T3, and T4 were measured. The data were analyzed by SPSS software using one-way ANOVA and Duncan&rsquo;s test. Results: In 50 soybean group, a significant decrease was observed in T4 serum level compared to the control group (p&lt;0.05). On the other hand, this hormone level non-significantly decreased in the group fed by 30 soybean compared to the control group (p&lt;0.05). TSH serum level increased significantly in 30 soybean group compared to the control group (p&lt;0.05). But, serum level of T3 was not significantly different between 30 or 50 soybean groups and control group (p&gt;0.05). Conclusion: In view of the findings, it is estimated that the effect of addition of soybean into meal on thyroid function is dose-dependent, so that the diet containing 30 and 50 soybean might cause increased TSH release in thyrotrope cells and hence variation in pituitary-thyroid axis function.</p

    Introduction: There is an interest in Crocous sativus L. (Saffron) mainly because of its biological properties. Biomedical research has focused on saffron as a powerful antioxidant, anti-inflammatory and anti-tumor, but its mechanism has not yet been thoroughly clarified. In this study, the effects of saffron aqua extract on matrix metalloproteinases (MMP) gene expression were investigated. Methods: In this experimental study, the saffron was extracted using water as solvent. MCF-7 cells in RPMI1640 medium were supplemented with 10 FBS and incubated at 37 ËšC with 5 CO2. After 24 h, the cells were treated by saffron extract at concentrations of 100, 200, 400 and 800 &mu;g/ml. 48 h after treatment, total RNA was extracted and cDNA was synthesized using specific primer. Synthesized products were analyzed by Real Time PCR to determine expression level of MMP. Results: Data analysis showed inhibitory effect of saffron at concentrations of 100 to 800 &mu;g/ml on MMP gene expression in comparison with control group. Reduction for 100, 200, 400 and 800 &mu;g/ml were 5, 18, 15, 11, respectively. According to data analysis treating MCF-7 cells with saffron at concentration of 200 &mu;g/ml caused the highest decrease, with 18 reduction in gene expression (P&lt;0.001). Conclusion: Results indicate decrease in the expression of MMP compared with controls revealing induction of inhibitory effects of saffron on angiogenesis which might be also considered as a promising chemotherapeutic agent in breast cancer treatment.</p

    A review of the most important medicinal plants effective on wound healing on ethnobotany evidence of Iran

    Get PDF
    Wound is referred to the disruption of joined structure of the body caused by physical, chemical, and biological agents. Wound healing is a reconstructive process which takes place after damage to skin and soft tissues. After damage, inflammatory response is developed and subdermal cells begin to increase the production of collagen and then epithelial tissue is gradually reconstructed. In Iran traditional medicine, natural substances and medicinal plants are used to heal wounds. This study was conducted to review the most important medicinal plants used for wound healing in different provinces of Iran. The key words including wound healing and skin healing combined with the words medicinal plants, ethnobotany, and traditional medicine in Iran were used to search for in the databases Information Sciences Institute, PubMed, Scopus, Islamic World Science Citation Center, and Magiran. The findings of this study on 15 different regions of Iran indicated use of 67 medicinal plants for wound healing. In some regions Scrophulariastriata, Althaea officinalis, Nerium oleander L. andPlantago major L. were jointly used for wound healing. The medicinal plants reported in this study with their wound-healing property are some alternatives that could be used to develop herbal medicines effective on wound healing if complementary studies confirm their properties

    Failure of germination among Apiaceae family seeds, e. g. cumin (Cuminum cyminum), has been reported by many investigators. Until now few works have been done on seed germination and seedling growth of cumin. In this research the effects of the exposure of cumin seeds to magnetic fields on seed germination, early growth, and enzyme activity have been studied under laboratory conditions. Seeds were magnetically exposed to one of three magnetic field strengths, 25, 50 and 75 mT for different periods of time (15, 30, and 60 min). The germination test was performed according to the guidelines issued by the International Seed Testing Association. Enzymes related to the germination process in magnetically exposed and unexposed germinating cumin seeds were assayed after 24 hours of imbibitions in distilled water. Exposure of cumin seeds to different intensities of magnetic fields prior to germination significantly increased germination-related characters. The increase in germination, speed of germination, shoot length, root length, total seedling length, seedling fresh weight, and seedling dry weight was, respectively, 14-17%, 14-57%, 8-27%, 25-62%, 16-39%, 10-29%, and 17-49% compared to untreated control seeds. The calculated vigor indices I and II also increased by 33-73% and 38-72%, respectively. In germinating seeds, enzyme activities of alpha-amylase, dehydrogenase, and protease were significantly higher in treated seeds in contrast to controls and the maximum value was 50 mT for 60 min exposures. The higher enzyme activity in magnetic-field-treated cumin seeds could trigger fast germination and early vigor of seedlings

    The effect of dietary virgin olive oil on brain lipid levels and brain edema in rat stroke models

    Get PDF
    Background and Objective: Stroke is the third most common cause of death in industrialized countries after cardiovascular diseases and cancer. Despite numerous defenses, the brain is vulnerable to oxidative stress resulting from ischemia and reperfusion. Due to the relationship between olive oil consumption and low cardiovascular mortality and morbidity, this study was accomplished to investigate the relationship between dietary virgin olive oil (VOO) on brain lipids and formation of brain edema in rat stroke models. Materials and Methods: In this experimental study 60 Wistar rats were divided into five groups. First and second groups (control and sham) received distilled water, while all three treatment groups received oral VOO for 30 days (0.25, 0.5 and 0.75 ml/kg/day respectively). Two hours after the last dose, each main group was subdivided into two additional groups of middle cerebral artery occlusion (MCAO) for the assessment of neuropathology (brain edema) and intact group for brain lipid analysis. Data were analyzed using one way Anova LSD tests and Pearson correlation. Results: Pretreatment by VOO increased the brain cholesterol ester and cholesterol levels in doses of 0.5 and 0.75 ml/kg/day. VOO in all three doses increased the brain triglyceride levels (p<0.05). Oral administration of VOO in doses of 0.5 and 0.75 reduced brain edema in mice. Conclusion: Results suggest that VOO may be taken as a valuable alternative for the pretreatment of ischemia via inducing some changes in lipid profile and decreasing brain edema
