results gelatin films exhibited good tensile strength and elongation at break, water solubility, swelling, and water vapor permeability. incorporation of tam into the gelatin films caused a significant decrease in tensile strength and swelling, and a significant increase in elongation at break, water solubility, water vapor permeability and whiteness of the films. gelatin films exhibited low an...

conclusions the current study results showed that silver nanoparticles produced by plantago ovata seed extract had an antibacterial effect on staphylococcus aureus which was resistant against cefixime, trimethoprim-sulfamethoxazole and penicillin. results the silver nanoparticles revealed gaussian distributions with the average diameter of 13 nm with some deviations, and results showed that the...

extracts obtained from the petals of rosa damascena (rosaceae) are used in iranian folk medicine as remedies for the treatment of some inflammatory diseases. in this study the hydroalcoholic extract and essential oil of the plant were investigated for its possible anti-inflammatory and analgesic activities. the extract was administered at the doses (p.o.) of 250, 500 and 1000?mg/kg and the dose...

purpose: to determine the maximum safe dose for intravitreal injection of anti-ctgf (ivac) in rat eyes in order to decrease gene and protein expression of connective tissue growth factor (ctgf) for the treatment of ocular fibrotic disorders. methods: forty-five lister hooded pigmented rats were divided into one of the five groups of 9 rats; 4 out of these 5 groups received different doses of iv...

the present study describes the radiation-induced effects on nutritional quality and on anti-nutritional factors of sorghum grain: effects of electron beam (er) and gamma irradiation (gr) at doses of 10, 20 and 30 kgy and infrared irradiation (ir) at 60, 90 and 120 s on the chemical composition, mineral content and bioavailability, in vitro protein and starch digestibility, total phenolic compo...

phytochemical investigation of the aerial parts of euphorbia erythradenia bioss. (euphorbiaceae), one of iranian endemic euphorbias, with particular attention to triterpene constituents, using methanol solvent extraction was carried out. five known triterpenes, including four cycloartanes and oleanolic acid, were isolated for the first time and identified using nmr and mass techniques. anti hiv...

conclusions preliminary results indicate that the native iranian actinobacteria could be considered a suitable option for screening of the new antibacterial compounds. molecular research and antibacterial compound extraction against the aforementioned pathogenic strains are also being conducted. results based on the morphological characterization, 35 isolated cases belonged to actinomycetes and...

conclusions this study indicated that some bacillus species have the potential to produce antimicrobial compounds which can be used to control microbial infections. results the identified bacillus species included b. cereus (86.6%), b. subtilis (6.6%), b. thuringiensis (3.3%), and b. pumilus (3.3%). evaluation of the antimicrobial activity of the extracted compounds was carried out against five...

pycnocycla spinosa decne. ex boiss. var. spinosa (fam. umbelliferae) is an essential oil-containing wild plant growing in central part of iran. hydroalcoholic extract of pycnocycla spinosa has antispasmodic and antidiarrheal activity. the aim of this study was to further investigate antidiarrheal and small intestinal transit effect of p. spinosa extract for a comparison with loperamide and dicy...

the chemical composition of the essential oils of flower at the pre-flowering, full-flowering and post-flowering stage of a. annua was analyzed by gc and gc/ms and sixty-two components were identified. the main compounds in the pre-flowering oil were β-myrcene (37.71%), 1, 8-cineole (16.11%) and camphor (14.97%). the full-flowering oil contained predominantly caryophyllene (19.4%), germacrene d...
