In: Nutrition Reports InternationalSummary: Se purifico exhaustivamente la fraccion de globulina de las semillas de Phaseolus vulgaris. Solo el 1.3 por ciento del contenido original de polifenol, el 3.1 por ciento de la actividad hemaglutinante y el 1.2 por ciento de la actividad antitriptica permanecieron en la fraccion de globulina. Se demostro una baja toxicidad en esta fraccion mediante inyecciones intraperitoneales en ratones y la incubacion in vitro de enterocitos de rata. Se observo una perdida de peso en ratones alimentados con la fraccion de globulina cruda en comparacion con los ratones testigo a los que se suministro caseina; esto no se atribuyo a una reduccion en la ingestion de alimentos. La coccion mejoro la digestibilidad de la proteina. No se observo hipertrofia pancreatica en ratones alimentados con la fraccion de globulina cruda pero si se observo atrofia del bazo. (RA-CIAT)Summary: The globulin fraction of Phaseolus vulgaris seeds was extensively purified. Only 1.3 percent of the original polyphenol content, 3.1 percent of the hemagglutinating activity, and 1.2 percent of the antitryptic activity remained in the globulin fraction. Low toxicity was demonstrated in this fraction by intraperitoneal injections in mice and by in vitro incubation with rat enterocytes. Wt. loss was observed in mice fed on the raw globulin fraction as compared with casein-fed controls; this was not attributable to a reduction in food ingestion. Protein digestibility was improved by cooking. No pancreatic hypertrophy was shown in mice fed on the raw globulin fraction but spleen atrophy was observed. (AS)
