Effect of aminoguanidine on in vitro maturation pig oocytes

Original language description

The effect of NOS inhibitor aminoguanidine, on in vitro meiotic maturation in the mouse was examined. In the present study we investigated the role of NO-dependent events in meiotic maturation in pig oocytes. Nitric oxide is involved in a wide range of functions: It determines vasodilation, inhibits platelet aggregation, control apoptosis and acts as a neurotransmiter. It has been suggested that NO-NOS has important physiological roles in a variety of reproductive processses such as follicular development, ovulation and spematogenesis. The synthesis of NO is catylyzed by three distinct isoforms of NOS: neuronal (nNOS), endotelial NO (eNOS) and inducible NOS (iNOS). Of the three NOS isoenzymes, ovaries express eNOS and iNOS but not nNOS. Cumulus-oocytescomplexes (COC) collected from porcine ovaries were examined with an inverted microscope and classifield as being at the following stages: oocytes at other stages of meiosis and atypical oocytes with degenerative changes or atypical morp
