Chlorpirifos (CPF) is a widely used organophosphate insecticide for both agricultural and domestic purposes with attendant human exposures. Many authors have documented the toxic effects of CPF on the central nervous system. This study was designed to study the effect of CPF and the influence of coadministration of ascorbic acid (AA) on the testicular functions of albino rats. Twenty five 2 mon...
INTRODUCTION Following orchiectomy patients with clinical stage I (CSI) testicular seminoma may be managed by active surveillance (AS) or adjuvant treatment (radiotherapy or chemotherapy). In view of the published data on long-term toxicity, mainly second malignant neoplasms (SMNs), adjuvant radiotherapy (ART) is currently no longer recommended as adjuvant therapy for these patients. The purpos...
Increased urinary concentrations of Polycyclic Aromatic Hydrocarbons (PAHs) and their metabolites are associated with increased risk of unexplained infertility in males. The toxicity of PAHs and dioxins are exclusively mediated through Aryl hydrocarbon Receptor (AhR). AhR overexpression contributes to the loss of normal ovarian function in polluted environments but its expression level in unexp...
BACKGROUND The testes have been considered a sanctuary site for leukemic cells and testicular relapses used to account for a major proportion of the poor outcome of boys with acute lymphoblastic leukemia. With use of aggressive chemotherapy which includes intermediate or high dose methotrexate, the incidence of testicular relapses has declined. However once these patients have received cranial ...
Humans have significant exposures to phthalates, as these chemical plasticizers are ubiquitously present in flexible plastics. Recent epidemiological evidence indicates that boys born to women exposed to phthalates during pregnancy have an increased incidence of congenital genital malformations and spermatogenic dysfunction, signs of a condition referred to as testicular dysgenesis syndrome (TD...
The 4-nitrophenol (PNP) in diesel exhaust particles (DEP) has been identified as a vasodilator and is a known degradation product of the insecticide parathion. In this study, the protective effect of quercetin, a potent oxygen free radical scavenger and metal chelator, against the oxidative damage of PNP on cultured testicular cells was studied in male embryonic chickens. Testicular cells from ...
β-cryptoxanthin (CRY), a major carotenoid of potential interest for health, is obtained naturally from orange vegetables and fruits. A few research studies have reported that CRY could decrease oxidative stress and germ cell apoptosis. The purpose of this study was to examine the effects of CRY on acute cadmium chloride (CdCl 2 )-induced oxidative damage in rat testes. For this study, 24 rats w...
In this study, it was aimed to determinate beneficial effects of Nerolidol (NLR) against reproductive toxicity caused by Thioacetamide (TAA). Male, 3-4-months-old, rats (n=32) were divided into four groups. Group-1 was kept as control and given corn oil as carrier. Group-2 received TAA (200 mg/kg, intraperitoneal (i.p.), two times per week) for 3 weeks, in group-3; NRL was orally administered a...
Testicular cancer represents the most curable solid tumor, with a 10-year survival rate of more than 95%. Given the young average age at diagnosis, it is estimated that effective treatment approaches, in particular, platinum-based chemotherapy, have resulted in an average gain of several decades of life. This success, however, is offset by the emergence of considerable long-term morbidity, incl...
The capacity of the testis to metabolize xenobiotics has been proposed to play a role in the susceptibility of different species to testicular toxicity. Since species differences in testicular xenobiotic metabolizing enzyme activities are not well documented, the primary objective of the present study was to compare enzyme activities in subcellular fractions prepared from rat, mouse, monkey, an...
