Objetivos: Demostrar la efectividad del Programa de intervención de enfermería en el incremento de los conocimientos sobre prevención de ITS y VIH-sida. Diseño: Cuasi experimental, con un solo grupo, antes y después. Institución: Facultad de Medicina, UNMSM. Participantes: Estudiantes ingresantes 2010. Intervenciones: En una muestra de 285 ingresantes 2010, se aplicó un cuestionario educativo estructurado, antes y después del programa de intervención de enfermería. Principales medidas de resultados: Evaluación vigesimal. Resultados: El puntaje promedio global de los conocimiento sobre prevención de ITS y VIH-sida. Antes del programa fue de 12 puntos: en Medicina 12,9, Enfermería 12,8, Obstetricia 12, Tecnología Médica 11,3 y Nutrición 10,4. Después de la intervención, el puntaje promedio de conocimiento en los estudiantes de la Facultad de Medicina fue 15,7; en Medicina...

Objective: To determine if Croton palanostigma (sangre de grado) oral administration modifies gastric secretion peptic activity. Design: Experimental study. Institution: Alberto Guzman Barron Biochemistry and Nutrition Research Center, Faculty of Medicine, Universidad Nacional Mayor de San Marcos. Biologic material: Adult male albino rats and sangre de grado. Methods: Fifty 200 to 250 g adult male albino rats were randomly distributed in 5 groups according to sangre de grado oro-gastric one dose administration: group I: 0,8 mL/kg of sangre de grado; group II: 0,8 mL/kg of neutralized sangre de grado; group III: ranitidine 50 mg/kg; group IV: control group with saline solution 0,9 g% (without histamine); group V: control group with saline solution 0,9 g%. Pyloric ligature by laparotomy was done under ethylic ether anesthesia. Subcutaneously applied histamine was used to stimulate secretio...

Objective: To determine liver and renal toxicity of Croton palanostigma latex oral swallowing, in therapeutic and larger doses. Materials and Methods: Sixty albino male rats were studied in two groups: one group swallowed for a short time during 7 days and another group swallowed ad libitum during 30 days. In each group there were 3 subgroups: (A) 1/1000 diluted latex (therapeutic dose), (B) 1/100 diluted latex, (C) water (control group). The animal weight and the water or diluted latex consumption were measured. Then, the rats were given ether anesthesia, their blood was obtained by cardiac puncture and centrifuged at 5000 rpm during 5 minutes to obtain plasma. Alkaline phosphatase and transferase glutamyl gamma activity were measured; urea, creatinine, total protein, albumin and globulin levels were studied by espectrophotometry. Results: The average latex consumption in the first grou...
