In the investigation carried out in the seed of Lupinus mutabilis Sweet it has been possible to identify by means of a Screening Phitochemistry the present biologically active principIes in the watery extract in boiled, being determined the total alkaloids.The acute toxicity has been evaluated (LD50) so much of the watery extract as of the obtained total alkaloids of the seed.In the watery extract of the seeds the activity antiinflammatory has been evidenced (acute and subchronicle) in experimental models, being administered the Lupinus for oral route to a dose of 2000 mg/Kg of weight. The inflammation was evaluated by different techniques using the technique of Granuloma of Pouche with trementin in rats (Inflammation sub-chronicle) and inflammatory to plant with formol to 1 % and ovoalbúmina to 50% in S.S.I. in mice, following the standard techniques of the CYTED, being obtained the ma...

In the present research, we have evaluated the effect of Lupinus mutabilis Sweet's seed, as watery and methanolic extracts on the gastric mucous of rats, following the Lee's method. Indometacin in doses higher than 50 mg per kg of weight causes lineal lesions, enlarging and dilatation of small intestine; partial obstruction, acute and chronic transmural granulomatous inflamation; abscess in the intestine's crypts and fibrosis. 2000 mg/kg of weight of the watery extract of the Lupinus was administered by mouth and 400 mk/kg of the methanolic extract by the same way.We use four groups of ten male rats each one with 250 g of weight approximately that were previously conditionated in our laboratory supplying food and water ad libitum. The animals were distributed in four groups in aleatory way and they received saline solution, ranitidine, watery extract of Lupinus and methanolic extract of ...

We evaluated the acute oral toxicity and the metabolic effect on glycemia and lipidemia in mice, of the metanolic extract of Notholaena Nivea, "Cuti-Cuti" to 10%, in CYTED models. The effect on plasma glucose was evaluated in normoglycemic and hyperglycemic rats, compared with control groups which received physiological serum. Hyperglycemia was induced with Alloxan, administered by intraperitoneal route to the dose of 150 mg/kg of weight. We used 60 rats distributed in three groups (I, II and III), of 20 rats each one. All the animals were put under 24 hours fasting, previous to the beginning of the experiments. Group I was subdivided in two sub groups of 10 animals each one and received physiological serum or extract of Cuti-Cuti, to observe its effects on normal blood glucose. The second group received alloxan to the dose of 150mg/Kg of weight, by intraperitoneal route, to induce exper...

Introducción: Camu-Camu, es un árbol frutal, oriundo de la amazonla sudamericana que crece en las orillas anegables de rlos amazónicos. Pertenece al genero Myrciaria, especie dubia. Presenta una gran importancia nutritiva. Su alto contenido en ácido ascórbico (2780 mg/lOO g de pulpa) le confieren propiedades antioxidantes.Objetivo: Evaluar la toxicidad subaguda (30 días) del Camu-Camu.Material y método: Utilizamos 33 ratas albinas. macho, Holt<;man, distribuidas en 3 grupos equitativos: Grupo I (grupo control), se leadministró agua destilada, Grupo 11 y Grupo 111, se les administró por vía oral el extracto seco de Camu-Camu a las dosis de 100 y 200mg/Kg, respectivamente. Al inicio del experimento (basal), a los 15 y a los 30 días, se determinó: hemoglobina, WBC, urea, albúmina, creatinina, proteínas, GOT, TGP, TGO, en sangre, y peso corporal; además, serealizó el exam...
