reports indicate that one of the causes of harmful to the genital system, especially the testes stress. stress could be created secondarily after some pathological conditions such as neurological diseases or environmental factors. one of the causes of stress could be scary voices, such as cat voice for mice. in this study we aimed to investigate the testes parameters in the animals that were ex...

recent studies show that synthetic glucocorticoids alter testicular homeostasis, in this regard, the influence of betamethasone as a glucocorticoid widely used on histological changes, epididymal sperm counts and fertility was explored in male mice. the study sample (50 mice) was allocated to 3 treatment groups, placebo and a control group. control group was no injected. only normal saline was ...

some studies suggested that glucocorticoid receptors activities can modulate fear and anxiety. according to that, the purpose of this research is to assess the modulatory effect of glucocorticoid receptors on the anxiety assessed in plus maze. in this research mice with medium weight of 20-25 g were used. the male and female animals separately sorted in two groups as control and experiment rand...

purpose: to evaluate the effects of silver nanoparticles on some serum parameters in mice. materials and methods: forty mice, including twenty male and twenty female, were randomly divided into eight groups: c1 and c2 (male and female control groups, respectively), t1, t2 and t3 (male treatment groups), t4, t5 and t6 (female treatment groups). after the acclimatization period, the treatment gro...

introduction dendritic cells (dcs) are bone marrow-derived cells, which migrate to lymphoid and non-lymphoid organs via blood. liver dcs are believed to play an important role in the regulation of hepatic allograft acceptance. however, because of inherent difficulties in isolating adequate numbers of dcs from liver, limited information is available on the phenotype and functions of liver dcs. t...

background: embryo cryopreservation is the process that water is removed from the cell by cryoprotectant materials, and embryos are stored at temperature below zero. this process may affect the viability and developmental potential of embryos. objective: in this study, the effect of the vitrification cryotop method on the expression level of oct4 and mest developmental genes in mouse blastocyst...

in this study we investigated histopathological changes of mice ovarian tissues following long-term administration of copper sulfate and induction of chronic copper poisoning. the study comprised of three different groups of twenty one mice as follows: the first group (group 100) which treated by gavage with copper sulfate at a dose of 100 mg kg-1 for 5 weeks. the second group (group 200), whic...

objectives: the aim of the present study was to evaluate protective effect of royal jelly on sperm parameters, testosterone level, and malondialdehyde (mda) production in mice. materials and methods: thirty-two adult male nmri mice weighing 30±2 g were used. all the animals were divided into 4 groups. control group: received saline 0.1 ml/mouse/day orally for 30 days. royal jelly group (rj): re...

the pharmacological interaction between cannabinoidergic system and vanilloid type 1 (trpv1) channels has been investigated in various conditions such as pain and anxiety. in some brain structure including hippocampus, cb1 and trpv1 receptors coexist and their activation produces opposite effect on excitability of neurons. in this study, we tested the hypothesis that trpv1 channel is involved i...

background: the present study was carried out to investigate the possible protective effects of royal jelly (rj) on oxymetholone (oxm)-induced oxidative liver injuries in mice. methods: in total, 32 adult male nmri mice were divided into four groups of eight mice each. mice in groups 1 and 2 were orally administered 5 mg/kg/day oxm for 30 days. at the same time, mice in group 3 received rj at a...
