Controlled-size maghemite (γ-Fe2O3) nanoparticles (NPs) were functionalized with zeolite 5A and cetyltrimethylammonium bromide (CTAB) by the co-precipitation method. The in situ after NPs synthesis procedures used to obtain five different nanomaterials that broadly characterized various physicochemical methods ensure magnetic remediation properties. γ-Fe2O3 sizes ranging from 4.5 12 nm obtained for bare also dispersed matrices of zeolites CTAB. Acute toxicity tests systematically performed...
Ruta graveolens L. y R. chalepensis son plantas usadas en medicina folclórica como antiespasmódicos, antihelmínticos, antimicrobianos, emenagogos abortivos. En el presente trabajo se evaluó efecto del extracto acuoso liofilizado (EAL) de las hojas embriones postimplantacionales ratón. Ratonas albinas preñadas recibieron intraperitonalmente (ip) 10 mg ruda liofilizada/kg peso corporal (grupo tratado, n=12) durante periodo post-implantacional (día 9 – día 17 post-cópula), un grupo control(C),...
The use of medicinal plants for the treatment illnesses is widely known. However, there are not many scientific reports about properties these and their side effects. In this study, effect aqueous extract Origanum vulgare on preimplantational mouse embryo development was investigated. oregano given ad libitum to four separated groups (n= 10) pregnant mice: O, 9, 18 y 36 mg/mL respectively. When embryos were evaluated, a slight delay in observed, but only with highest dose. With respect...
In this work, we provided a Tropaeolum tuberosum hydroalcoholic extract to male mice (780 mg kg-1) for 7, 14 and 21 days treatment, there was no significant difference in body weight gain, testes, epididymides prostate (p> 0.05), nevertheless progressive motility decreased immobile sperm count increased significantly after treatment (p <0.05). The the epididymis cauda 3 three assessments, concentration on lower than those of 7 treatments Our results suggest, that T. has direct action...
El creciente interés por la medicina natural hace necesaria evaluación de las propiedades plantas, así como sus posibles efectos secundarios. En años recientes se han reportado los tóxicos varias plantas medicinales sobre el desarrollo preimplantacional ratón (Benavides et al, 1998; Benavides al., 1999), muchas cuales producen malformaciones y alteraciones en embrionario. Ruta graveolens "ruda", Origanum vulgare "orégano" Persea americana "palta" son usadas folklóricamente para aliviar...
The "maca", Lepidium meyenii Walp, is a peruvian native plant and resource with wide nutritional value. Several investigations had been realized in the last decade to probe "maca" effects on mammals fertility. In this work, we assessed of lyophilizade aqueous extract L. preimplantational embryos Mus musculus. Two concentrations 0 g/Kg (control group) 1 body weight were supplied two groups pregnant female mice, respectively from day 4 pregnancy. stage development, conditions embryo morphology...
The aim of this study was to investigate the effect administration aqueous extract Brugmansia arborea (L.) Lagerheim-Angel's Trumpet-on some reproductive parameters in mammals.Male mices were treated with 70 mg/kl/cw for 7 days, where they euthanized and its testis, epididymis cauda region weights determinate; so, sperms number abnormalities accounted. testis tail weight fell; sperm concentration lower than control rises. These results suggest that there is a negative dose B. would alter...
It was evaluated in vivo the cytoprotective capacity of fruit Myrciaria dubia H.B.K. MC VAUGH "Camu- camu (Myrtacea) against mutagenic damage caused by potassium bromate (68.5 mg/k) on three mouse cell lines (liver, kidney and blood cells). Mice (n = 120) were divided into groups which drank ad libitum: distilled water; TI (negative control) TIII (positive control), TII group aque- ous extract (2 %) Camu-camu. After ten days, only intraperitoneally injected with a single dose KBr03(68.5...
Magnetic iron oxides nanoparticles (NPs) functionalized with lysine (Lys) and arginine (Arg) was obtained by following chemical co-precipitation route in basic medium. The synthesis performed mixing ferrous chloride (FeCl2•4H2O), ferric (FeCl3•6H2O) the specific amino acid a molar ratio of 1: 2: 0.5, respectively. High pH sample washed several times distilled water to reach similar (Ph=7) after process, part NPs dried. Of measurements XRD MS that samples are magnetic maghemite about 9 nm...
Maytenus macrocarpa (Chuchuhuasi) es un árbol nativo de la región Amazónica del Perú utilizado como planta medicinal para el tratamiento muchas enfermedades, sin embargo su efecto sobre sistema reproductor masculino aún no ha sido elucidado.

The present study describes the morphological aspects of testis and presents a general characterization seminiferous elements adult specimens (N=8) Allobates femoralis (Boulenger, 1883) collected at Panguana Biological Station (9°37'S 74°56'W), 250 masl, upstream Pachitea river, Yuyapichis district, Puerto Inca province, Huanuco, Peru. The amphibians (25.99 ± 0.97 mm in length) were dissected their testes isolated for macroscopic descriptions; later, routine histological protocols...
Introduction: Myrciaria dubia known as “camu camu” is a fruit that grows in the Amazon and its main characteristic high content of vitamin C. Ascorbic acid has protective role spermatogenesis it compound excellent reducing action. The purpose this research was to evaluate vivo cytoprotective capacity aqueous extract (Kunth) McVaugh “camu-camu” against mutagenic damage produced by antineoplastic drug cyclophosphamide (CP) on male germ line. Methodology: Mice (n= 60) were divided into five...
Introducción Después del confinamiento COVID19, cuando se restablecieron las actividades presenciales en los establecimientos educacionales (EE) kioscos escolares mantuvieron cerrados por problemas económicos dudando si una oferta apegada a la Ley 20.606 es económicamente viable. La evidencia ha demostrado que un kiosco escolar con orientación hacia hábitos saludables de alimentación impacta positivamente el consumo alimentos saludables, preferencia estudiantes y viable como unidad apoyo EE....
Introducción Las políticas públicas generadas para mejorar la salud y nutrición se han enfocado en impactar los ambientes alimentarios (AA) con el objetivo de transformar las conductas alimentarias (CA) población, tal como lo evidencia Ley 20.606. Esto, función dos premisas: i) problemáticas nutricionales son estructurales carácter sistémico; ii) enfoques sobre elección alimentos saludables una decisión individual no representado solución CA e incidir prevalencia obesidad. Ahora bien,...
The Blue-headed macaw (Primolius couloni) is considered a New World endangered parrot. Blood samples were collected from 13 captive blue-headed macaws (7 male, 6 female) housed in the Las Leyendas Zoological Park Lima, Peru to establish hematologic reference values. Mean values for erythrocytes and leukocytes 2608 x 103/ml 10.11 respectively; hematocrit was 50.15% mean corpuscular volume 200 fl. differential leukocyte count showed 64.7 25.3% of heterophils respectively. largest smallest...
We investigated antitumor effect of aqueous extract Bomarea cornigera. Swiss albino mice strain were inoculated with tumor cell line TG-180 for 15 days, after which they separated into 5 groups (n= per group). Cyclophosphamide was administered intraperitoneally (positive control), distilled water (negative control) and the at concentrations 1X, 2X 4X; morbidity, mortality, weight length sarcoma assessed. found an inhibitory B. cornigera in development solid where transplanted.
