melanin pigment plays a critical role in camouflage and   protection against harmful effects of solar radiation. melanogenesis is under   complex regulatory control by multiple agents. tyrosinase is a   multifunctional, which catalyzes the first two steps in mammalian   melanogenesis. in this study, inhibitory effects of astragalus fasciculifolius   and astragalus gypsicolus on diphenolase acti...

شناخت عملکرد یک اکوسیستم طبیعی و آگاهی از پتانسیل آن، نیاز به آگاهی از مشخصه‌ها و معرف‌های خاکی و گیاهی دارد. ارزیابی ویژگی‌های مهم خاک و پوشش گیاهی می‌تواند ما را از توانایی‌های موجود مرتع آگاه نموده و تعیین وضعیت آن را میسر سازد. هدف از این مطالعه مقایسه و تعیین عملکرد شاخص‌های سطح خاک در لکه‌های اکولوژیک موجود در دو دامنه شرقی و غربی مراتع لیشتر در استان کهگیلویه و بویراحمد است. بدین منظور د...

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...

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...
