ABSTRACT
The Metabolic Syndrome (MS) is a set of alterations that increase the risk of developing type 2 diabetes mellitus (DM2). There is evidence that obesity and the development of metabolic syndrome lead to alterations in cognitive processes. In this work it was proposed to determine if generating the metabolic syndrome produces changes in the electric unitary spontaneous activity in the hippocampus as a possible sustain of the learning alterations. In Wistar rat with a hypercaloric diet, metabolic syndrome was provoked, and this was confirmed with the determination of body and metabolic parameters as a measure of intraperitoneal fat, glucose, triglycerides, and cholesterol. Electrophysiological records were made in the hippocampus and it was determined that rats treated with a hypercaloric diet show a significant decrease in such activity. Thus, it is shown that rats that were caused metabolic syndrome, alter their hippocampal electrophysiological activity.
ABSTRACT
OBJECTIVE: To determine the level of knowledge about nourishment/nutrition and how this knowledge is distributed among school adolescent population in the town of Cádiz. DESIGN: Descriptive and transversal study. SETTING: Schools. PARTICIPANTS: Sample of 630 subjects from the school adolescent population in the town of Cádiz. MEASUREMENTS AND MAIN RESULTS: The average level of knowledge about nourishment/nutrition is 6.63 (in a 0-13 scale). No significant differences were found according to the perception of proportion or disproportion in height and weight, level of concern about body fats and getting fat, diets, avoiding some food or taking some medication, dietary fibers and infusions or any other weight-reducing products and physical exercise and fitting. The relationship between the level of knowledge and the BMI is very close to statistical significance. CONCLUSIONS: We found a middle level of knowledge about nourishment/nutrition. We think this level of knowledge should be raised and other factors determining healthy habits should be considered. It is necessary to go on with research and contextualize nourishment habits.

Se estudiaron los bazos de ratas Spragne Dawley. Utilizadas en estudios subcrónicos de 30 y 60 días, y en el estudio crónico de 180 días, así como los bazos procedentes de cerdos, caballos, bovinos y conejos sanos y adultos, los que fueron procesados por el método de parafina y colorados por la técnica especial de Pels, con el objetivo de investigar si constituye un proceso patológico la presencia de hemosiderina en el bazo de estas ratas. Se evidenció una gran cantidad deshemosiderina en los bazos de estas, que fue mucho mayor en los animales de más edad, aspecto que no se observó en los bazos de otras especies. se concluye que es un hecho normal la presencia de abundantes depósitos de hemosiderina en el bazo de las ratas Spragne Dawley
