background: radiotherapy has many side effects on fertilization in young women. radiation can lead to ovarian failure in women who underwent abdomen or pelvic radiotherapy. objective: this study helps us to investigate ovarian response of nmri female mice to ovarian stimulating hormones (pmsg, hcg) after whole-body gamma irradiation. materials and methods: 45 pregnant mice were divided into two...

background: previous investigations have revealed, cimetidine, a histamine h2-receptor antagonist, show radioprotective effects against gamma- and neutron-induced micronuclei in bone marrow erythrocytes. in this study, the anticlastogenic effects of famotidine and ranitidine, which act similar to cimetidine as histamine h2-receptor antagonists, was investigated. materials and methods : balb/c m...

background: the present study has been carried out to investigate the effects of preovulatory stage gamma-irradiation of female mice in the absence or presence of vitamin e on numerical chromosome abnormalities in 8-cell embryos after mating with non-irradiated males. materials and methods: the 8-11 weeks adult female nmri mice were whole body irradiated at preovulatory stage (post pmsg injecti...

methods retrospective cohort study of blunt trauma patients with rib fractures at a level i trauma center that had both a cxr and a ct chest. the ct finding of ≥ 3 additional fractures in patients with ≤ 3 rib fractures on cxr was considered clinically meaningful. student’s t-test and chi-square analysis were used for comparison. results we identified 499 patients with rib fractures: 93 (18.6%)...

conclusion despite multiple exposures, ed control is more effective if wss is performed using apmdr in the aec mode. results using apmdr, the mean number of exposures was 6.1 for ap and 6.5 for lat projections. lat projections required more exposures (6.55%) than ap projections. the mean ed was 0.6276 msv (ap) and 0.6716 msv (lat). the mean ed for lat projections was 0.6061 msv in automatic exp...

Sulfation of glycosaminoglycans and giycopeptides was com pared in baby hamster kidney (BHK) cells and the polyoma virus transformants (PY-BHK). Cells were incubated with | fH ]glucosamine and pSJsulfate, and the labeled glycosaminoglycans and giycopeptides were isolated by digesting the cell membrane fraction with pronase followed by gel filtration. Each type of giycosammoglycan in the void vo...
