N-Acetyl-L-cysteine (NAC) has been widely used in the protection against the toxic effects produced by several chemicals because of its radical scavenger properties and because NAC is a precursor of glutathione, one of the most important intracellular defenses against oxidants. The aim of this investigation was to verify the potential protective activity of(More)
Although the teratogenic potential of some glycol ethers and their active metabolites, the alkoxyacids, is well known, a comparative in vitro study of the embryotoxic potential of such compounds has not yet been conducted. The present study investigates the relationship between chemical structure and embryotoxicity of three glycol ethers (methoxy-, ethoxy-(More)
The mechanism involved in diabetes-induced embryotoxicity is still unclear. Mitochondrial alterations probably produced by oxidative stress have been described in embryos developing in a diabetic environment. Furthermore, oxygen radicals-scavenging enzymes can reduce the embryotoxic effects induced by diabetic conditions. In this work we tried to test if(More)
The addition of physiological concentrations (1 nM) of tri-iodothyronine (T3) to the culture medium of Sertoli cells from prepubertal (8-day-old) rats stimulated both protein synthesis (+55%) and lactate (+50%) production, while it inhibited DNA synthesis (-30/35%) and aromatase activity (-45/50%); insignificant T3-dependent effects were observed in(More)
The morphogenesis of the aortic arch system was studied in rat embryos whose mothers had been treated with glycerol formal (GF) during pregnancy. The fetuses were removed from the uterus on days 13-17 of gestation and India ink was injected into their vascular system while they were still alive. The teratogenic effect of GF manifested itself by(More)
The aim of the present study was to investigate the influence of thyroid hormones on androgen metabolism in Sertoli cells isolated from 3- and 4- week-old rats. Hypothyroidism was induced by the oral administration of 0.025% methimazole (MMI) from birth until the rats were killed at 3 and 4 weeks of age. Half of the MMI-treated animals were injected i.p.(More)
In order to evaluate the effect of dipromochloropropane (DBCP) on reproductive function, groups of male adult Wistar rats were injected subcutaneously with different doses of DBCP. A strictly dose-dependent effect resulting in histological alteration principally toward the seminiferous tubules was observed. Sperm count and sperm motility showed azoospermia(More)
The embryotoxicity of four different anthracyclines [doxorubicin (DOXO), epirubicin (EPI), daunorubicin (DAUNO) and idarubicin (IDA)] was compared using the postimplantation whole embryo culture method. Moreover, to investigate the role of free oxygen radical production in anthracycline-induced embryotoxicity, the reduced glutathione (GSH) status in embryos(More)
To evaluate a possible relationship of maternal exposure to anticancer drugs during the preimplantation period to blastopathies and postimplantation embryotoxicity, CD female rats were injected intraperitoneally on day 3 of pregnancy with 15 and 30 mg/kg of cyclophosphamide (CPA), 2 and 4 mg/kg of Adriamycin (ADR), 3 and 6 mg/kg of cis-platinum (Cis-Pt), or(More)
