In the present study, we tried to establish an efficient assay for total antioxidant capacity (TAC) in human plasma using a 96-well microplate. TAC was assessed using lag time by antioxidants against the myoglobin-induced oxidation of 2,2'-azino-di(3-ethylbenzthiazoline-6-sulfonic acid (ABTS) with hydrogen peroxide, and expressed as Trolox equivalent. The linearity of the calibration curve with...
Traditional semen analysis is routinely used for the assessment of male infertility. The present study aimed to evaluate the application of molecular techniques in determining the DNA integrity of the spermatozoa of infertile men in comparison to conventional analysis. Semen samples from 52 infertile patients were analyzed by conventional assays, flow cytometry (FCM) analysis for sperm DNA inte...
UNLABELLED Divalent cations (calcium, magnesium, zinc, cooper, manganese) play an important role in various biological processes. Different acute or chronic renal disorders in children or adults modify the urinary excretion of these cations and may influence their concentrations in organism. AIM Evaluation of the changes of some divalent cations levels (Cu, Zn, Mg, Ca) in acute renal diseases...
PURPOSE To determine the activity of seminal plasma catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPX) and their relationship with malondialdehyde (MDA), as a marker of lipid peroxidation, content of spermatozoa and seminal plasma in normozoospermic and asthenozoospermic males. MATERIALS AND METHODS Semen samples were obtained from 15 normozoospermic and 30 asthenozoo...
Evidence for the conservation of biological activity of ovulation-inducing factor in seminal plasma.
An ovulation-inducing factor (OIF) in the seminal plasma of llamas and alpacas (induced ovulators) and cattle (spontaneous ovulators) suggests that OIF is a conserved constituent of seminal plasma among mammals. In this study, three experiments were designed to determine the biological effects of OIF in different species. In experiment 1, superstimulated prepubertal female CD-1 mice (n=36 per g...
background: momordica charantia (m. charantia) seed has been supposed to have an antifertility property but mechanisms underlying the infertility effect have not been investigated. objective: we investigated the antifertility effect of m. charantia ethanol seed extracts on reproductive toxicology and seminal and plasma testosterone in male wistar rats. materials and methods: the control group (...
