Resumen
Descripción general del contenido del recurso.
In vitro maturation of oocytes is a critical step in the in vitro embryo production and for this reason new protocols to optimize that process has been developed. Theophylline and fenoterol in oocyes trigger fundamental process in nuclear and citoplasmatic maturation of oocytes. Both substances are mainly used in humans as broncodilators in obstructive airway diseases, such as bronchial asthma, and for myocardial and nervous central sistem stimulation. Both medicines has been proposed for substitution of gonadotrophins FSH and LH because their comparable action and low cost. Not obstant, some researchers have found genotoxic and mutagenic effects of theophylline, that can damage any cellular process by its capacity to affect the genic expression and their products, which could be result counterproductive in the in vitro maturation of oocytes protocol optimization. On the other hand, no reports have been found on the genotoxicity and mutagenicity of fenoterol; for this reason, the citotoxicity by tripan blue exclution of theophylline and the genomic integrity by comet assay of theophylline (0.02, 0.2 y 2 mM) and fenoterol (0.1, 1 y 10 mM) has been assessed in this study. We have not found citotoxic and genotoxic effects of theophylline in periphery human limphocytes. No clastogenic effects at the concentration 0.1 and 1 mM used in the in vitro maturation of oocytes were noted, but strong clastogenic effect at 10 mM was found.
