Název v původním jazyce

Effect of aminoguanidine on in vitro maturation pig oocytes

Popis výsledku v původním jazyce

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
