background:in recent years, the use of chemicals in agriculture, industry, and public health has become so common that the environment is continuously contaminated by the toxic substance-like metals. aluminum released due to anthropogenic activities such as mining and industrial uses. aluminium has several industrial uses. the present study was designed to investigate the effect of aluminium ch...

Microcystins (MCs) induce the production of reactive oxygen species (ROS) in various tissues in mammals, whereas the endogenous antioxidant enzymes are responsible to scavenge the ROS. ROS can modulate the antioxidant enzyme activities by regulating the mRNA levels. The present study was undertaken to find out the relationship between the transcriptional alterations of antioxidant enzymes and M...

Spermatogenesis is a complex process of male germ cells proliferation and maturation from diploid spermatogonia, through meiosis, to mature haploid spermatozoa. The process involves dynamic interactions between the developing germ cells and their supporting Sertoli cells. The gonadal tissue, with abundance of highly unsaturated fatty acids, high rates of cell division, and variety of testis enz...

Background: Radio frequency wave (RFW) generated by mobile phones and wireless communication systems has been reported to cause adverse effects on reproductive function, vision and hematological parameters, possibly through oxidative stress. The aim of this study was to evaluate the effect of RFW generated bybase transceiver station BTS on oxidative stress in testis, eye and erythrocyte, and th...

The stimulation of oxidative stress and lipid peroxidation of liver tissues by AFB1 has been extensively investigated. However, the effect of AFB1 on antioxidant enzyme activities and gene expression in testis has not been completely elucidated. The current study investigated the histopathological picture and activities in addition to gene expression of antioxidant enzymes in testis of rats int...

Introduction: Sexual dysfunction and infertility are frequently associated with diabetes in men and experimental animals. Oxidative stress and alteration in testis are responsible for complication in diabetes. Saffron has antidiabetic and antioxidant properties that improves the functions of various organs. Therefore, the aim of the present study was to investigate the effects of administra...

The aim is to study the effect of Tartrazine (E102) – synthetic food colour – on the antioxidant status of testis of Wistar rats. Twelve male Wistar rats were grouped into 2 groups of six each – Control and Tartrazine-treated groups. Control group was orally administered with water alone while the experimental group was orally administered with tartrazine dissolved in water. The treatment was c...

Metals and metalloids are involved in the production of free radicals, the causing factor for oxidative stress. However, metals and metalloids are also necessary components of specific antioxidant enzymes. In brain tissues, knowledge about the spatial distribution of these elements may help to explain the etiology of neurodegenerative disorders. The investigation of their distribution in the te...

background: the present study describes the susceptibility of prepubertal testis of mice to prooxidant induced oxidative impairments both under in vitro and in vivo exposure conditions. materials and methods: following in vitro exposure to iron (5,10 and 25 m), oxidative response measured in terms of lipid peroxidation and hydroperoxide levels in testis of pre pubertal mice (4 wk) was more robu...
