P-101: Effects of Ethanol and Strontium on Growth and Development of Two-Cell Arrested Mouse Embryos
Background: Arresting in a certain step of development like two-cell stage could be one of the reasons of infertility. The aim of this study is evaluating the effects of ethanol and strontium on growth and development of two-cell arrested mouse embryos. Materials and Methods: The females were coupled with male following superovulation. Positive vaginal plug mice were killed 48 hours after hCG i...
In this study the role of glutathione (GSH) in sulfur mustard -induced oxidative stress and cytotoxicity, in human skin fibroblast cell line (HF2FF) was evaluated. Sulfur mustard-induced superoxide radical and hydrogen peroxide formation were evaluated by determination of superoxide dismutase and catalase activity in cell lysate. The cytotoxicity of sulfur mustard was estimated by lactate dehyd...
the effect of dietary sucrose on dna formation in rat liver and kidney compared with that of starch was studied. male, weanling rats were fed for 6 and 14 days on diets containing 68% 'sucrose or 68% starch, and liver and kidneys were examined for 1ilie amount and rate of formation of dna; and also for content of fat, protein, and moisture. food intake and weight gain were estimated. sucrose fe...
objective(s): for the development of reliable, ecofriendly, less expensive process for the synthesis of silver nanoparticles and to evaluate the bactericidal, and cytotoxicity properties of silver nanoparticles synthesized from root extract of croton bonplandianum, baill. materials and methods: the synthesis of silver nanoparticles by plant part of croton bonplandianum was carried out. the for...
some new water-soluble schiff base complexes of na2[m(5-so3-1,2-salophen)].nh2o; (5-so3-1,2-salophen = n,n’-bis(5-sulphosalicyliden)-1,2-phenylendiamine); na2[m(5-so3-2,3-salpyr)(h2o)n].2h2o; (5-so3-2,3-salpyr = n,n’-bis(5-sulphosalicyliden)-2,3-diaminopyridine); and na2[m(5-so3-3,4-salbenz)(h2o)n].nh2o; (5-so3-3,4-salbenz = n,n’-bis(5-sulphosalicyliden)-3,4-diaminobenzophenon); where m = cu, n...
Background: Fine Needle Aspiration (FNA) of thyroid gland has greater sensitivity as compared to other diagnostic modalities for thyroid nodules. The present study was conducted to compare the sonographic findings of cold thyroid nodules with cytologic changes. Materials and methods: For 219 patients, sonography of thyroid nodules was performed by 7.5MHz probes and the following changes were r...
