Full textLepidium meyenii Walp. (maca) (Brassicaceae) is widely used as a folk medicine, for the ability to enhance the sexual performance in humans, rats and mice, besides to improve the spermatogenesis. However, the way maca acts on spermatogenesis still unclear. In this study, adult male mice were treated with maca aqueous extract during periods of 7, 14 and 21 days, after each treatment, physiological parameters were measured and the expression of cyclin A1 (Ccna1), cytochrome P450 17α-hydroxylase/17,20-lyase (Cyp17), protamine 2 (Prm2) and steroidogenic acute regulatory protein (StAR) (genes involved in spermatogenesis), were recorded. The results shows that maca increased significantly (p less than 0.05) sperm concentration in the three treatment groups, plus Ccna1, CYP17 and Prm2 expression were not significantly affected, while StAR, shows a negative regulation on their expression in groups of 7 and 14 days of treatment. These results suggest, that the mechanism maca increases sperm concentration is not related to increased meiotic activity, or the synthesis of testosterone, but rather the response of a component with androgenic activity present in the aqueous extract of maca, evidenced by the negative effect on StAR expression. These results re-enact the importance of maca as reproductive enhancer without running the risk of increased androgen contraindicated in cases of prostate cancer.

Full textIn the present study was carried out the enzymatic hydrolysis of carbohydrates, fibers (cellulose) and of proteins contained in Maca, natural resource very diffused at world level, with the purpose of unfolding the components and nutritious of Maca to simpler and more assimilable units for the human beings. The following commercial enzymes were used: cellulase (Celluclast® 1.5 L), amylase (Fungamyl® BG), multienzyme (Viscozyme® L) and peptidase (Neutrase ®), the same ones that were provided by Novo Nordisk. It was designed a preliminary test using twelve evaluation or treatment of Maca´s powder with an enzyme or combinations of these. When it was used two or three enzymes, in some cases these they were applied in sequential form and in other they were applied simultaneously. The reaction conditions were standardized for all the preliminary systems. Then, five were selected to present better reaction conditions and bigger quantity of sugars reducers and proteins. The analytic results in the five tested systems show us that the concentration of sugars reducers, product of the unfolding of carbohydrates reaches concentrations among 77 to 90 g %, in the sub products of hydrolysis. However the protein concentration reaches values among 20 to 33 g % for action of the protease, there being identified 13 amino acids by chromatography in two-dimensional fine layer. Likewise the presence of two alkaloids was demonstrated in Maca´s powder, which were identified also in the sub products of hydrolyses, demonstrating that these hydrolysis processes don't affect the structure of these metabolites. Key words: Maca´s powder, enzymatic hydrolysis, industrial enzymes, assimilable components.

Full textDetermina que el extracto etanólico de las hojas de once especies del género Croton: Croton baillonianus, Croton draconoides, Croton lechleri, Croton cuneatus, Croton palanostigma, Croton thurifer, Croton sp, Croton adipatus, Croton zehntneri, Croton tarapotensis y Croton ferrugineus contienen flavonoides que tienen actividad citotóxica. Las hojas de las especies estudiadas fueron sometidas a maceración etanólica, con cuyos extractos se realizó una cromatografía en escala preparativa en papel sistema descendente, aislándose 13 tipos de flavonoides, los cuales son responsables de la actividad citotóxica en las líneas celulares L 929 y MDCK. Para la identificación de los flavonoides se utilizaron tres parámetros, el primero fue el cambio de coloración de las bandas cromatográficas cuando se expusieron a la luz ultravioleta y vapores de amoniaco, luego estas bandas se eluyeron con metanol y se realizó la segunda prueba de identificación de flavonoides mediante la reacción de Shinoda, y en tercer lugar, se realizó la prueba espectrofotométrica UV-Visible, cuyos máximos de absorción confirmaron la presencia de flavonoides. Se determinó el efecto citotóxico de los flavonoides obtenidos mediante un bioensayo de citotoxicidad en líneas celulares L 929 y MCDK, este bioensayo permitió estimar la viabilidad celular que fue determinada mediante la coloración MTT, la absorción del color desarrollado se midió a 540nm. El análisis Probit permitió determinar la IC50 e IC70, es decir la actividad citotóxica de los flavonoides. De acuerdo a los resultados, los trece flavonoides extraídos presentaron actividad citotóxica, sin embargo, la isoflavona presente en Croton ferrugineus C se distingue por su alta capacidad citotóxica frente a ambas líneas celulares MDCK y L 929, convirtiéndose en un potencial agente anticancerígeno.

Full textEn la presente investigación se evaluó la actividad leishmanicida y la toxicidad aguda oral del látex de Euphorbia weberbaueri “Leche leche”, previa elucidación de los principales componentes fitoquímicos. La actividad leishmanicida fue evaluada a las dosis de 287, 575 y 863 mg/Kg por el método del granuloma de la pata del hámster inducido por Leishmania peruviana con el objetivo de determinar la dosis efectiva media. El estudio se realizó de forma comparativa con el antimoniato de N-metilglucamina (Glucantime) al 1% como control positivo. La toxicidad oral aguda se determinó en ratones albinos mediante la dosis letal media (DL50), para lo cual se ensayaron tres niveles de dosis del extracto a 2000, 200 y 50 mg/kg. Además, fueron identificados los principales grupos de metabolitos secundarios presentes en el látex de tallos frescos, mediante un tamizaje fitoquímico y por Resonancia magnética nuclear. Se encontró que el extracto posee un efecto leishmanicida comparable al que presenta el antimoniato de N-metilglucamina (Glucantime), y se obtuvo 26,4; 41,5 y 50,1% de inhibición en la formación del edema en correspondencia con las diferentes dosis ensayadas. Al determinar la DL50, se encontró que una dosis de 817,01 mg/Kg provoca inhibición en la formación del edema en un 50%. Al estimar la DL50 comparativa no se encontraron diferencias significativas entre ambos y los valores de DL50 del extracto y el vehículo fueron de concentración de 13,05 y 16,25 mL/Kg respectivamente, correspondiendo la primera a 1803,11 mg/Kg sobre la base de los sólidos totales. Estos resultados permiten validar el empleo y la seguridad del uso tradicional del látex de Euphorbia weberbaueri para tratar problemas de salud relacionados con leishmaniasis.

Full text-- The wound healing effect of vegetal specie Peperomia scutellaefolia R. et P. was evaluated in this research using tensiometric methods and the results were corroborated with histological studies in order to observe and analyze the histological evolution in each case. Batch Balb C 53 albine mice with 25g of average weight were used and treated with Carbopol 940 gels with 5%, 10%, 20% and 30% W/W concentrations of this vegetal extract. The results obtained were compared with two groups: the control group (without treatment) and another group treated with a commercial medicament. A better wound healing effect with Peperomia’s 5% W/W concentration gel was obtained. Flavonoids derivates of dihidroflavonols and isoflavones nuclei were founded and identified by ultraviolet and infrared spectrophotometry and coloration reactions. Description of the morphological external characteristics of Peperomia scutellaefolia R. et P. such as peltates leafs, spiciform influorescent, subterranean stem was done. Also some microscope details such as pluristratificate epiderm and idioblastes in the leaf’s lamine were described. Petioles and peduncles with pigments, periderm and crystals of Calcium oxalate in the subterranean stem (corm) were founded. This information could simplify the identification and differentiation of another species from genus Peperomia. n order to document the usage and therapeutic aplications of this plant in the traditional medicine of Cajamarca ethnopharmacology inquires were carried out. This plant is used fresh or dry to treat cardiac diseases, internal inflamations and to heal external wounds.

Estudio de diseño prospectivo, analítico, experimental y longitudinal. Se distribuyó 48 ratas albinas macho, raza Holtzman, de 21 días de edad, al azar, en seis grupos y se les dio dietas isocalóricas (54% carbohidratos, 13% proteínas,33% grasa),“ad libitum”, con composiciones de grasa distintas: grupo “Control” (n=5),100% de aceite de cocina; grupo “A” (n=8), 100% de aceite de sacha inchi extra virgen; grupo “B”(n=8),100% de manteca de palma; grupo “C” (n=8), 95% de manteca de palma y 5% de aceite de sacha inchi; grupo “D” (n=8), 50% de manteca de palma y 50% de aceite de sacha inchi ; grupo “E” (n=8), 5% de manteca de palma y 95% de aceite de sacha inchi. Además, el grupo “Basal” (n=3), al cual no se le dio alimento y que, por el contrario, fue eutanasiado para determinar en él las condiciones iniciales del proceso. Después de 30 días, los animales de los seis grupos fueron igualmente eutanasiados y se recolectaron muestras sanguíneas, histológicas hepáticas y vasculares aórticas, así como datos de peso corporal, hígado, corazón e ingesta. Los seis grupos que fueron alimentados presentaron pesos corporales, viscerales y de ingesta aproximados entre sí, con tendencia al mantenimiento y disminución. Las variables del perfil lipídico no han presentado diferencias estadísticamente significativas al compararse entre grupos (p>0,05). Sin embargo, los valores de Colesterol total (grupo B: 93,5 ± 28,6; grupo C: 86,65 ± 20,2; grupo D: 80,3 ± 16,6; grupo E: 74,2 ± 22,0; grupo A: 68,6 ± 21,5) y de lipoproteína de alta densidad (HDL-col) (grupo B: 55,2 ± 10,6; grupo C: 50,2 ± 10,5; grupo D: 45,03 ± 10,2; grupo Control: 43,1 ± 8,5; grupo A: 40,8 ± 6,7; grupo E: 39,2 ± 8,3) han disminuido conforme mayor ha sido la proporción de aceite de sacha inchi en la dieta; sin afectarse notablemente el índice CT/HDL-c. En contraste, los valores correspondientes al grupo Basal han sido generalmente mayores a los demás (CT, LDL-col, VLDL-col, TG). La evaluación del tejido hepático mostró degeneración grasa que se incrementaba en casos y en cuanto al compromiso hepático derivado, de manera concomitante a la disminución en la proporción de aceite de sacha inchi en la dieta: los grupos B y C mostraron degeneración difusa y distorsión en la citoarquitectura del hepatocito en más de la mitad de sus integrantes; los grupos D y Control tuvieron degeneración de menor compromiso estructural; los grupos A y E, predominio de tejido sin cambio graso. En cambio, en el tejido vascular aórtico no se apreció acumulación lipídica en las muestras evaluadas. El aceite de sacha inchi ha tenido un efecto hipocolesterolemiante no significativo y discutible en cuanto a su capacidad protectora frente a la enfermedad cardiovascular; así como, un efecto antiesteatótico en el tejido hepático y cambios mínimos no atribuibles a acumulación de lípidos en las muestras evaluadas de tejido vascular aórtico, en ratas albinas alimentadas con dietas altas en grasa saturada durante 30 días.
