Objective(s) Cigarette and nicotine enhances embryogenesis, fertility, pregnancy loss and ultrastructure alterations of oocyte. This study was performed to determine the effect of daily supplementation of vitamin E on oocytes apoptosis in nicotine-treated mice. Materials and Methods In this experimental study, 24 NMARI adult female mice were randomly allocated into four experimental groups. ...

Background: Since the deleterious effects of reactive oxygen species (ROS) during sperm cryopreservation can be overcome by antioxidants, post-thaw human sperm quality may perhaps profit from adding antioxidants to the extender media prior to cryopreservation. This study evaluated the effects of different concentrations of Trolox supplementation to cryo-protective media on post-thaw motility an...

Purpose: To exaluate the effect of perfluorocarbon on lung ischemia-reperfusion injury in rats, and to unravel potential underlying mechanism.Methods: A total 36 Sprague-Dawley (SD) rats were randomly assigned sham group, model group (12 per group). The levels inflammatory factors (TNF-α IL1β) determined using enzyme-linked immunosorbent assay (ELISA). Cell apoptosis was evaluated by terminal d...

Crataegus species have been widely used in herbal medicine, especially for the hearth diseases. In the present study, the effect of Crataegus aronia var. dentata Browicz extract on partially hepatectomized rats was investigated with biochemical and TUNEL apoptosis assays. The extracts of the plant at the concentrations of 0.5 and 1 ml/100 g body weight/day were administered orally to the two ex...

Purpose: The aim of the study explores probable toxic effects vancomycin on kidney and analysis protective melatonin.
 Materials Methods: In this study, rats were randomly divided into 4 groups: control group; melatonin (10 mg/kg/day) vancomycin-treated (200 mg/kg) + group. Rats in treatment group given two doses a day with an interval seven consecutive days once daily for days. experiment...

Introduction: In this study, the effect of para-nonylphenol as an environmental pollutant on viability, morphology and proliferation of bone marrow mesenchymal stem cells was investigated. Methods: Bone marrow mesenchymal stem cells of rat were treated with the 0.5, 1, 2.5, 3.5 and 5 μM of paranonylphenol for a period of 21 days, then the viability of the cells were estimated using trypan bl...

An association between DNA fragmentation in sperm determined by the terminal deoxynucleotidyl transferase [TdT]-mediated deoxyuridine triphosphate (dUTP) nick end labeling (TUNEL) assay and the incidence of reproductive failure has been reported, either using flow cytometry or optical microscopy. However, the results obtained using each of these two approaches are different. Since there is a re...

p-nonylphenol (p-np) as a non ionic surfactant is used in many industries such as pesticides, cosmetics,detergents and so on. our previous study showed that the p-np causes reduction in viability of the rats bonemarrow mesenchymal stem cells (mscs). the aim of the present study was to investigate the mechanism of the cell death due to p-np exposure. the cells, after 3rd passage were treated wit...

background and objective: sensory neurons have critical role in improvement of functional outcome of any neuroprotective strategy. the herbal medicine nepeta menthoides has been reported to have anti-apoptotic effect on axotomized spinal motoneurons. in the present study, the putative neuroprotective effect of nepeta menthoides on the axotomized dorsal root ganglion sensory neurons in neonate r...
