Abstract Background: Anxiety is a psychological and physiological state characterized by somatic, emotional, cognitive, and behavioral components. Anxiety is considered to be a normal reaction to stress, however excessive anxiety results in anxiety disorder. In this study, we investigated the possible interaction between nicotine and nitric oxide system of the dorsal hippocampus on anxiety-l...
Background: The beneficial effect of supplementing culture medium with melatonin has been reported during in vitro embryo development of species such as mouse, bovine and porcine. However, the effect of melatonin on the mouse somatic cell nuclear transfer remained unknown. Materials and Methods: In this study, we assessed the effects of various concentrations of melatonin (10-6 to 10-12 M) on t...
the purpose of this study was to evaluate the efficiency of intracytoplasmic sperm injection (icsi) and piezo-assisted sperm injection after pretreatment with calcium ionophore (cai) on the mouse embryo development. methods: in this study, the conventional icsi and piezo-icsi procedures were used. the efficacy of the methods was examined after mouse matured oocytes were fertilized with or witho...
This study was designed to investigate the role of GABAB receptor agents on imipramine-induced antinociception in ligated and non-ligated mice using hot-plate test. The data showed that different doses of morphine (3, 6, and 9 mg/kg) induced a dose-dependent antinociception in ligated and non-ligated mice. However, the opioid response was decreased in ligated animals. Intracerebroventricular (i...
Purpose: This Study evaluated the resumption of meiosis, in vitro maturtion and department of immature mouse oocytes with b- mercaptothanol. Materials and methods: Immature oocytes were recovered from NMRI mouse strain (4-6 weeks) in different 4 experiments groups: the control group, the oocytes were matured in MEM-a+ medium containing + FCS 55%; group 1: the oocytes were matured in MEM- a med...
conclusions it seem that melatonin due to its antioxidant properties, if added to glycerol based media, reduces the harmful effects of freezing-thawing process, and protects seminiferous tubules histological structure from oxidative injury. results the result showed that supplementation of glycerol based media with melatonin has reduced injury to histological structure of seminiferous tubules i...
