cancers belong to a group of disorders which are very important for researchers. because they have several types and cause mortality in human beings. many investigations are performing in order to introduce cheaper drugs with lower side effects especially with natural sources. ferula genus grows all over the world but some of them are endemic to iran. many investigations have proved differe...
BACKGROUND In Iranian folk medicine, several plants are used for treatment of gastrointestinal disorders, such as diarrhea and spasm. One of these herbal medications are the essential oil yielded from seeds of Ferula assa-foetida L. and an oleo-gum-resin known as asafetida, which is exudated from its root. F. assa-foetida grows wildly in south and central mountains of Iran. AIM In this study,...
This study was done to investigate the nutritive value of Festocaovina, Agrostisgiganta and Avena sativa using sheep rumen and feces liquor as sources of micro-organism through gas production method. Rumen and feces liquor were collected from three fistulated sheep. Rangeland species sampling was randomly conducted from different areas of Guilan province. All the collected samples were initiall...
Phytochemical investigation of the dichloromethane extract of the dried roots of Ferula badrakema resulted in the identification of one new and six known compounds. Known compounds were sesquiterpene coumarins: mogoltacin, feselol, badrakemin acetate, ferocaulidin, conferone and conferol acetate. The new compound was a sesquiterpene, named badrakemonin. The structures of these compounds were el...
Understanding interactions between grasses and their herbivores is central to the conservation of species-rich grasslands and the protection of our most important crops against pests. Grasses employ a range of defenses against their natural enemies; silicon-based defenses have been shown to be one of the most effective. Silicon (Si) is laid down on the leaf surface as spines and other sharp bod...
Genetic diversity may play an important role in allowing individual species to resist climate change, by permitting evolutionary responses. Our understanding of the potential for such responses to climate change remains limited, and very few experimental tests have been carried out within intact ecosystems. Here, we use amplified fragment length polymorphism (AFLP) data to assess genetic diverg...
جهت شناخت اثر متغیرهای محیطی بر پراکنش گروههای اکولوژیکگیاهی، ابتدا با استفاده از سیستم اطلاعات جغرافیایی و با همپوشانی نقشههای توپوگرافی و زمین شناسی، تعداد 50 واحد همگن زمینی انتخاب و در تودۀ گیاهی معرّف هر واحد، اقدام به نمونهبرداری از پوشش گیاهی شد. برای اندازهگیری اطلاعات پوشش گیاهی، در واحدهایی با گیاهان بوتهای از 30 پلات دومترمربعی و در واحدهایی که گیاهان درختچهای نیز حضور داشتند از...
Introduction: Considering the prevalence of epilepsy and the failure of available treatments for many epileptic patients, finding more effective drugs in the treatment of epilepsy seems necessary. Oxidative stress has a special role in the pathogenesis of epileptic syndrome. Therefore, in the present study, we have examined the anti-epileptic and anti-oxidant properties of the Ferula Assa Foeti...
با توجه به وجود تغییرات مداوم در اکوسیستمهای طبیعی بویژه مراتع، تنوع عوامل تأثیرگذار و هزینه زیاد اندازهگیری مستقیم، کاربرد تکنیکهای جدید در مطالعات مختلف ضروری میباشد. در این تحقیق کارایی تکنیکهای آمار مکانی در ارزیابی تغییرات پوشش تاجی گونه festuca ovina l. مورد بررسی قرار گرفت. پوشش تاجی با استفاده از پلاتهای نمونهبرداری در 45 رویشگاه ثبت شد. سپس از روش معکوس وزنی فاصله و کریجینگ برای...
