the cytotoxicity of the biomaterials is a key issue that should be addressed prior to pre-clinical applications. this study was designed to evaluate and compare the cytotoxixity of two forms of bioactive glasses:nanopowder:andmicropowder. human hgf1-pi53 gingival fibroblast cells were used to evaluate the cytotoxicity of 0.5, 1, 1.5, 2, 5, 10, 15 and 20 mg/ml concentrations of the two bioactive...
پیش زمینه و هدف: رسوراترول (3، 4، 5 تری هیدروکسی- ترانس استیل بن، یک استیل بنوئید)، نوعی ترکیب فنول طبیعی است. این ترکیب در پوست انگور قرمز، همچنین در ریشه knotweed ژاپنی (polygonum cuspidatum گیاه هفت بند) نیز وجود دارد. رسوراترول همچنین در گیاه gnetum cleistostachyum (از تیره گیاه ریش بز) نیز وجود دارد. در سال های اخیر مطالعاتی در خصوص خواص ضدالتهابی و ضد کانسری این ترکیب بخصوص در کانسرهای گو...
background and objectives: angiogenesis is essential for tumor survival. inhibiting angiogenesis could be a mechanism for hindering tumor development. numerous studies have now been focused on agiogenesis inhibitors and many of such studies have targeted plant materials. in the present study, crocus pallasii subsp. haussknechtii has been evaluated for anti-angiogenesis properties. methods: anti...
background and objectives: cancer is a public health problem all over the world. herbal medicines have a vital role in the prevention and treatment of cancer and large numbers of plants and their isolated constituents have shown potential anticancer activity. methods: twenty seven medicinal plants from southern iran provinces have been extracted with methanol and screened for their cytotoxic ac...
it has been reported that several members of convolvulaceae family such as convolvulus arvensis possess cytotoxic activity on some tumor cell lines. proteoglycan mixture, the water extract of c. arvensis with high molecular weight, has potent anti-angiogenesis and stimulating effects. in this study, arial parts of c. arvensis were collected and identified, and the cytotoxic effects of chlorofor...
background: although pentavalent antimony compounds are used as antileish-manial drugs but they are associated with limitations and several adverse complica-tions. therefore, always effort to find a new and effective treatment is desired. in this study, the effect of zno nanoparticles with mean particle size of 20 nanome-ters (nm) on leishmania major promastigotes and amastigotes was evaluated....
در تحقیق حاضر غشاهای پلیمری ساخته شده از نانوکامپوزیت پلی هدرال الیگومریک سیلسسکویی اکسان( poss) و پلی کربنات یورتان (pcu) به منظور بررسی کاربرد احتمالی به عنوان جایگزین موقت پوست با استفاده از رده سلولی 929 l مورد بررسی های زیست سازگاری شامل آزمون سمیت سلولی، آزمون تکثیر سلولی و مشاهدات میکروسکوپ الکترونی(sem) قرار گرفتند. منحنی ftir فیلم پلیمری کلیه قله های مورد انتظار در نانوکامپوزیت یاد شده...
iran has 1260 km of coastline that borders the persian gulf and the oman sea in the northwest indian ocean. marine algae are one of the natural resources in the marine ecosystem which produce a wide range of new secondary metabolites with various biological activities that play an important role in the pharmaceutical care. in this study the cytotoxic activity of 28 marine algae of chabahar coas...
the genus stachys belongs to lamiaceae family with about 300 species and worldwide distribution. in the present study, the cytotoxic activity of four fractions of different satchys species (s. byzatina c. koch., s. inflata benth., s. setifera ten. and s. persica gmel.), has been investigated against ht-29 (colon carcinoma), caco-2 (colorectal adenocarcinoma), t-47d (breast ductal carcinoma) and...
introduction: this study aimed to compare the cytotoxicity of mta fillapex, ah-26 and apatite root canal sealers at different times after mixing. methods and materials: in this in vitro study, mta fillapex, ah-26 and apatite root canal sealer were spilled uniformly by 40 µm mesh in a 96-well plate. then, human fetal foreskin fibroblast cell line (hfff2) were added to each sealer cell culture me...
