this research aims to evaluate the effects of seed scarification on five perennialastragalus species including a. effusus, a. vegetus, a. subsecundus, a. brevidens and a.cyclophyllon in the field conditions. seeds were sown after scarification with sandpaper byhand in the field of homand absard rangeland research station, damavand, iran in autumnin 2008. the seeds were sown using split plot des...
This study was carried out to evaluate the effects of Astragalus on human nasopharyngeal carcinoma (NPC) viability and apoptosis and to investigate the mechanism of Astragalus in a NPC cell line (CNE2). Cell viability was measured using the MTT assay. CNE2 cells treated with Astragalus were stained with acridine orange/ethidium bromide and subjected to fluorescence microscopy. Bcl-2, Bax, caspa...
The balanced grazing is a critical managing factor regarding to resource conservation and quantitative and qualitative increase of plants production at the rangeland ecosystems. In addition, understanding the effects of different grazing intensity on the dominant plants can be used as a valuable tool in order to resource management. The current study aimed to determine vulnerability and toleran...
Intra-specific variability of root biomass production (RP) of six rooted macrophytes, i.e. Juncus effusus, Phragmites australis, Schoenoplectus lacustris, Typha latifolia, Phalaris arundinacea, and Iris pseudacorus grown from clones, in response to Cu exposure was investigated. Root biomass production varied widely for all these macrophytes in control conditions (0.08 μM) according to the sampl...
Astragalus L., is one of the largest genuses of flowering plants in the Leguminosae family. Roots of A. membranaceus Bge. var. mongholicus (Bge.) Hsiao, A. membranaceus (Fisch.) Bge. and its processed products are listed in the China Pharmacopeia for "qi deficiency" syndrome treatment. However, more and more researches on other species of Astragalus have been conducted recently. We summarize th...
Sulfate and selenate uptake were investigated in both selenium (Se) hyperaccumulators (Astragalus racemosus and Astragalus bisulcatus) and closely related nonaccumulator species (Astragalus glycyphyllos and Astragalus drummondii). Sulfur (S) starvation increased Se accumulation, whereas increased selenate supply increased sulfate accumulation in both root and shoot tissues. cDNAs for homologs o...
BACKGROUND Astragalus memebranaceus is a traditional Chinese herbal medicine used in treatment of common cold, diarrhea, fatigue, anorexia and cardiac diseases. Recently, there are growing evidences that Astragalus extract may be a potential anti-tumorigenic agent. Some research showed that the total saponins obtained from Astragalus membranaceus possess significant antitumorigenic activity. Ga...
Astragalus membranaceus is commonly used in traditional Chinese medicine for strengthening the host defense system. Astragalus membranaceus-polysaccharides is an effective component with various important bioactivities, such as immunomodulation, antioxidant, anti-diabetes, anti-inflammation and neuroprotection. In the present study, we determine the effects of Astragalus membranaceus-polysaccha...
مطالعة رفتار اکولوژیکی گیاهان بهعنوان عناصر اصلی اکوسیستم و ویژگیهای رویشگاهی آنها گامی اساسی در جهت یافتن راهحلهای مناسب برای حفظ، اصلاح و احیاء این بخش مهم از منابع طبیعی تجدید شونده است. گیاه مرتعیAstrgalus effusus متعلق به خانوادة بقولات و از گیاهان خوشخوراک و دائمی مناطق نیمهاستپی است. بهمنظور مطالعه آتاکولوژی این گونه، ابتدا رویشگاههای آن در استان مشخص شد؛ سپس ویژگیهای رویشگاهی شامل...
Astragalus polysaccharide is an important bioactive component of Astragalus membranaceus, an herb used in traditional Chinese medicine for treating inflammatory bowel disease. The NOD-like receptor protein 3 inflammasome plays an important role in the pathogenesis of inflammatory bowel disease. However, little is known about the role of NOD-like receptor protein 3 inflammasome in Astragalus pol...
