Efecto del consumo del extracto de quinua en anemia ferropénica inducida en ratones / Effect of quinoa extract consumption on iron deficiency-induced anemia in mice

RESUMEN

RESUMEN Objetivos Determinar efecto del consumo del extracto de quinua en anemia ferropénica inducida, en ratones. Material y Métodos Se utilizaron treinta ratones albinos M. musculus de la cepa Bal-b/c, machos de peso promedio 24±32,7 g. Se formó tres grupos de diez ratones cada uno a) grupo control negativo hierro suficiente(HS),recibió 40g/d de alimento balanceado durante siete semanas; b)grupo control positivo hierro deficiente (HD), recibió 40g/d de dieta ferropénica durante siete semanas; y, c) grupo experimental hierro defi-ciente(HD), recibió 40g/d de dieta ferropénica durante siete semanas y a partir de la semana cinco se agregó 20g/d de extracto de quinua(EQ). Se midió el nivel de hemoglobina. Resultados Al finalizar el tratamiento, se observó diferencia significativa en los niveles de hemoglobina entre los grupos control positivo (8,9±1,1g/dL) HD y experimental (11,4±0,5 g/dL.) HD+EQ (t student, p<0,05). No se encontró diferencia significativa en los niveles de hemoglobina, al término del periodo de inducción entre los grupos control positivo (9,1±1,1) HD y experimental (9,3±0,7) HD (t student, p>0,05). Conclusiones En condiciones experimentales, la quinua presenta efecto antianémico, sustentado en los resultados de los niveles de hemoglobina.(AU)

ABSTRACT

ABSTRACT Objectives To determine the effect of quinoa extract consumption on iron deficiency-induced anemia in mice. Materials and Methods Thirty male M. musculus albino mice of the Balb/c strain, with an average weight of 24±32.7 g, were used. Three groups of ten mice each were formed 1) a negative control group of iron-sufficient (IS) mice that received 40g/d of balanced feed for 7 weeks; 2) a positive control group of iron-deficient (ID) mice that received 40g/d of feed rich in iron for 7 weeks; and 3) an experimental group of ID mice that received 40 g/d of feed rich in iron for 7 weeks and 20 g/d of quinoa extract (QE) from week 5. Hemoglobin levels were measured. Results At the end of the treatment, a significant difference was found in hemoglobin levels between the positive (ID mice 8.9±1.1 g/dL) and experimental (ID+QU mice 11.4±0.5 g/dL) groups (student's t, p<0.05). No significant difference was found in hemoglobin levels at the end of the induction period between the positive (IS mice 9.1±1.1) and experimental (ID mice 9.3±0.7) groups (student's t, p>0.05). Conclusions Under experimental conditions, quinoa has an antianemic effect based on the results of hemoglobin levels.(AU)
