although some vitamins have been shown to prevent glucocorticoids induced osteoporosis in short time, the magnitude of this effect remains to be clarified. the aim of this study was to evaluate protective effect of vitamin d3 on methylprednisolone acetate (mpa) induced osteoporosis in rats. twenty-four male sprague dawley rats were randomly divided into four groups: group a (n = 6), was a base ...
chemical composition of the essential oils extracted from the leaves, stems, flowers and seeds of heracleum rechingeri manden. were analyzed by gc and gc/ms. twenty-four components were characterized for the leaf oil with octyl acetate(47.2%), octanol(15.2%) and e-caryophyllen (5.7%) as the main constituents. 25 compounds were identified in the stem oil with elemicin (65.3%), octyl acetate (13...
a gradient reversed-phase high performance liquid chromatography (hplc) method was developed for the assay of cetrorelix acetate, a synthetic decapeptide with gonadotropin-releasing hormone (gnrh) antagonistic activity used in infertility treatment. the hplc method, which is used to determine cetrorelix in bulk and pharmaceutical dosage forms, was validated per ich guidelines. the chromatograph...
the multivariate calibration method, partial least square regression (pls) was applied for thesimultaneous spectrophotometric determination of lidocaine (lid) and hydrocortisone acetate(hca) in their mixtures. the parameters of chemometric technique were optimized and theproposed method was validated with synthetic samples and applied to analyze these drugs inpharmaceutical products with good a...
pregnancy prevention raises much concern to many pet owners. female cats usually show undesirable behaviour during oestrus. nowadays, researchers try to explore the reliable and effective ways to prevent oestrus signs in queens. the results of their studies prove that hormone therapy is probably one of the most reliable methods for this purpose. the aim of our study was to compare the effect of...
objective: the immunomodulatory effect of geranial, geranial acetate, gingerol, and eugenol essential oils were evaluated by studying humoral and cell-mediated immune responses. materials and method: the essential oils were evaluated for immunomodulatory activity in in vivo studies, using rats as the animal model. the essential oils were tested for hypersensitivity and hemagglutination reaction...
چکیده زمینه و هدف: انتظار می رود که جمعیت جهان در سال 2180 بیش از 10 میلیارد نفر برسد. تقریباً 95% رشد جمعیت در کشورهای درحال توسعه رخ می دهد. اجرای برنامه های تنظیم خانواده، علاوه بر پیشگیری از موالید پرخطر، می تواند بهبود قابل ملاحظه ای را در کوتاه مدت و درازمدت بر کیفیت زندگی زنان داشته باشد. با توجه به اهمیت تنظیم خانواده و لزوم برنامه ریزی دقیق ارزیابی آگاهی زنان در مورد عوارض روشهای تنظیم ...
fe3o4 nanoparticles were synthesizedviaa simple chemical reaction between fecl2.4h2o and fe(no3)3.9h2o under nitrogen atmosphere at room temperature, and then nanoparticles were added to cellulose acetate (ca) polymer. the influence of nanoparticles on the thermal properties of ca polymeric matrix was studied using thermogravimetric analysis (tga). nanostructures were characterized by x-ray dif...
یکی از سوختهای مناسب جهت جایگزینی سوختهای فسیلی بیواتانول میباشد. میتوان از ضایعات کشاورزی در تولید بیواتانول استفاده کرد. در فرایند تولید بیواتانول مرحله آماده سازی خوراک (پیشتیمار) یکی از پر هزینه ترین و مشکلترین مراحل تولید بیواتانول است. در این تحقیق ضایعات برنج به عنوان خوراک تحت آماده سازی به وسیله مایع یونی 1-ehyl-3-methylimidazolium acetate و نیز ترکیب آن با پیشتیمار بازی (naoh) قرار گرفت.
the effect of acetate ion introduced to aqueous solutions was investigated for the extraction/separation of ni and co from a dilute sulfate media. the separation of co and ni was improved by introducing acetate to aqueous media. by the use of the slope analysis method,the stoichiometric coefficient of the extractant was found to be 4 for cobalt and 3.5 or 4 for nickel depending on the acetate c...
