The mammalian testes are generally quite susceptible to cadmium. A deficiency of metallothionein (MT), a metal-binding protein linked to Cd tolerance, has been observed in rat testes and may explain the sensitivity in rats. Little is known about the metal-binding proteins in primate testes. Thus this study examined the nature of these proteins in a non-human primate species, the patas monkey (E...

Bi-n-butyl phthalate (BNBP) is an environmental pollutant. The aim of this study was to evaluate the protective effect of lipoic acid (LA) against testicular dysfunction associated with the intake of to BNBP- intoxicated rats. Adult male Wistar rats were divided into 4 groups of 6 animals each, and received medication orally for 14 days. Group I rats received 0.5 ml corn oil. Group II rats rece...

cyclophosphamide (cp) is extensively used as an antineoplastic agent for the treatment of various cancers, as well as an immunosuppressive agent. however, despite its wide spectrum of clinical uses, cp is known to cause several adverse effects including reproductive toxicity. crataegus monogyna is one of the oldest pharmaceutical plants that have been shown to be cytoprotective by scavenging fr...

Since cyclamates were first introduced in the early 1950s, arguments have raged over the potential carcinogenicity of this artificial sweetener. Concern over the safety of cyclamates arises from observations that some individuals and experimental animals can metabolize cyclamate to cyclohexylamine and that cyclohexylamine has been shown to produce testicular atrophy in experimental animals. Thi...

BACKGROUND Reproductive toxicity of Atrazine (ATR) was evaluated in two rat multigenerational studies. Development of male reproductive parameters was evaluated in separate studies after prenatal or postnatal exposure. METHODS In multigenerational studies, rats received dietary concentrations of 0, 10, 50, 100 or 500 ppm ATR. In separate studies in female rats, ATR was administered by gavage ...

An important target organ for thyroid hormone activity is the testis and hypo or hyperthyroidism causes noticeable alterations in testicular function. This study aimed to investigate therapeutic effect of Coriander Seeds Extract (CSE) against thyroidectomy induced toxicity, oxidative stress, injury, proliferation male testes rats. 40 rats were equally divided into 4 groups [Gp1, control; Gp2, C...

The health hazards of individual organophosphorus insecticides have been characterized by their acute toxicity, mainly by investigating their cholinesterase inhibition. However, the chronic effects of most of these toxicants on the drug-metabolizing enzymes have not been investigated. Profenofos (O-4-bromo-2-chlorophenyl O-ethyl S-propyl phosphorothioate) is an organophosphorus pesticide widely...

FK 506 is a macrolide antibiotic with powerful immunosuppressive activities. It is known to prevent allograft rejection in rats, dogs, monkeys, baboons, and humans. 1.2 In vitro studies indicate that, like cyclosporine (Cy A), FK 506 acts specifically by inhibiting the transcription of a limited set of early T-cell activation genes, including those encoding interleukin-2 (IL-2), IL-3, IL-4, and...

Testicular cancer has become a model for a curable neoplasm. Our studies with cisplatin combination chemotherapy allow us to conclude that: (a) short-duration intensive induction therapy with the most active agents in optimal dosage is more important than maintenance therapy; (b) modest dose escalation increases toxicity without improving therapeutic efficacy; (c) it is possible to develop cura...
