Se han determinado los índices mitótico y de fases de Alliurn porrum "poro" cultivados en condiciones de laboratorio (18-20°C). Se utilizaron meristemos radiculares de 2-3mm de longitud, los cuales fueron procesados mediante la técnica del aplastamiento "squash" y coloreados con orceina-acetoclorhidrica (2%) . El índice mitótico paraA.porrumfué de 7.83% y los índices de fase: profase (49.94%), metafase (12.22%), anafase (4.59%),telofase (33.25%) respectivamente. Se observó la presencia de figuras mitóticas modificadas como: rnetafases alteradas (3.37%), puentes anafásicos (4.49%), y puentes telofásicos (1.39%), que representu el 0.084% de la población meristemática total. Estos resultados demuestran que el ciclo celular de A. porrum es dinámico y constante; y podría constituir un modelo "centinel" alternativo para estudios de cinética celular y toxicidad ambiental.

β-Amyloid (Aβ) is a toxic peptide that has a high propensity for aggregation, and it is often present in the brains of patients with Alzheimer's disease (AD). Bioactive compounds from medicinal plants with neuroprotective properties are of interest in protecting against toxic forms of the Aβ peptide. In the present work, we evaluate the in vitro antiaggregant / disaggregating capacity of amyloid and amyloid-type aggregates by the anthocyanins of Zea mays L. (purple corn). Using the differential pH method, we quantified the total anthocyanin content. With the help of spectrophotometric readings of the amyloid-like protein-Congo Red and Aβ-Congo Red complexes, we evaluated the antiaggregation and disaggregation effects of anthocyanins on amyloid peptides and amyloid derivatives. The results showed a significant activity of antiaggregant / disaggregating capacity by anthocyanins, (33.54...
