ABSTRACT
El fruto del borojó (Borojoa patinoi cuatrec.) es reconocido en la tradición popular por sus propiedades como conservante, posiblemente relacionadas con la presencia en él de compuestos fenólicos. En esta investigación se evaluó el contenido de polifenoles y su actividad antimicrobiana frente a patógenos como Escherichia coli y Staphylococcus aureus. El fruto del borojó tiene un contenido de polifenoles que oscila entre 600 y 800 mg ácido gálico/100gr, y actividad antimicrobiana frente a S. aureus y E. coli, determinada por halos de inhibición entre 12 y 9 mm respec ivamente. Estos resultados muestran el potencial que tiene este fruto de la familia de las Rubiaceae como posible agente antimicrobiano para ser utilizado enla industria agroalimentaria y cosmética.
According to popular belief, borojó (Borojoa patinoi cuatrec.) fruit is recognized for its preservative properties, possibly related to the presence of phenolic compounds. The content of polyphenols and their antimicrobial activity against pathogens as Escherichia coli and Staphylococcus aureus were evaluated in this research. Borojó fruit has polyphenol content between 600 and 800 mg gallic acid/100gr, and antimicrobial activity against S. aureus and E. coli with inhibition halos between 12 and 9 mm respectively. These results showed the advantages that have this fruit from the Rubiaceae family as a potential antimicrobial agent in food and cosmetics industries.

This article reports a successful clinical regimen of treatment for the Class II furcation defect. Twenty-eight patients with molar teeth demonstrating Class II furcations were treated with regenerative therapy with the goal of regenerating lost interradicular periodontium. The treatment selected included scaling and root planing, surgical flap design that would enable the flap to completely cover the surgical site, complete enucleation of granulation tissue, tetracycline root conditioning, a particulate autogenous bone graft, and an expanded polytetrafluoroethylene (e-PTFE) membrane. Of the twenty-eight consecutive patients treated, twenty-five demonstrated no postoperative clinical evidence of furcation invasion, for a success rate of 89%. Eleven sites were reopened 8 to 9 months postsurgical and presented complete furcation fill with a hard, bone-like tissue. Three teeth were judged to be failures because clinical assessment revealed persistent furcation invasion. The absence of histologic evidence precludes the presumption that complete periodontal regeneration occurred.
