Tillán Capó,Juana; Gómez Mirabal,Juan Miguel; Menéndez Castillo,Rosa;
Revista Cubana de Plantas Medicinales , 2005,
Abstract: the lowering lipid activity of the aqueous extract and of the gel of aloe vera l., both freeze dried, was evaluated on albine mice in an acute model of hyperlipidemia induced with triton. the animals were intraperitoneally administered 500 mg/kg of aloe vera l. aqueous extract or gel, according to the treatment, together with 200 mg/kg of triton. a control group with sodium chloride solution 0.9 % and a control group of the model administered with triton were included. 18 hours later, the concentrations of total cholesterol and its fractions of high and low density and triglycerides were determined in serum. significant reductions ( p <0.01) of the concentrations of total cholesterol, triglycerides and ldl-cholesterol were found in the serum of animals treated with gel, as well as with the aqueous extract in relation to the concentrations obtained in the group of animals treated with triton only. it may be concluded that the aloe vera l. extract and its gel revealed a lowering lipid effect at the assayed dose in the model of hyperlipidemia induction (triton), probably by interruption of the feedback mechanisms inhibiting the endogenous lipidic synthesis.

Revista Cubana de Plantas Medicinales , 2005,
Abstract: Se evaluó la actividad hipolipemiante del extracto acuoso y gel de Aloe vera L. en un modelo agudo de hiperlipemia inducida con tritón. Se utilizaron ratones Suizos machos de 25 a 30 g de peso corporal y los productos empleados se prepararon a partir de las hojas frescas de la planta y finalmente se liofilizaron. Los animales fueron administrados por vía intraperitoneal con 500 mg/kg de extracto acuoso o gel de A. vera según el tratamiento, conjuntamente con 200 mg/kg de tritón; se incluyó un grupo control con solución de cloruro de sodio al 0,9 % y un grupo control del modelo administrado con tritón. Al cabo de las 18 h se realizaron las determinaciones en suero de las concentraciones de colesterol total y sus fracciones de alta y de baja densidad y de triglicéridos. Tanto en el suero de los animales tratados con gel como con el extracto acuoso se encontraron reducciones significativas (p<0,01) de las concentraciones de colesterol total, triglicéridos y col-LDL en relación a las concentraciones obtenidas en el grupo de animales tratados sólo con tritón. Se puede concluir que tanto el extracto de A. vera como el gel revelaron un efecto hipolipemiante a la dosis ensayada en el modelo de inducción de hiperlipemia con tritón, probablemente por interrupción de los mecanismos de retroalimentación inhibitorios de la síntesis lipídica endógena The lowering lipid activity of the aqueous extract and of the gel of Aloe vera L., both freeze dried, was evaluated on albine mice in an acute model of hyperlipidemia induced with triton. The animals were intraperitoneally administered 500 mg/kg of Aloe vera L. aqueous extract or gel, according to the treatment, together with 200 mg/kg of triton. A control group with sodium chloride solution 0.9 % and a control group of the model administered with triton were included. 18 hours later, the concentrations of total cholesterol and its fractions of high and low density and triglycerides were determined in serum. Significant reductions ( p <0.01) of the concentrations of total cholesterol, triglycerides and LDL-cholesterol were found in the serum of animals treated with gel, as well as with the aqueous extract in relation to the concentrations obtained in the group of animals treated with triton only. It may be concluded that the Aloe vera L. extract and its gel revealed a lowering lipid effect at the assayed dose in the model of hyperlipidemia induction (triton), probably by interruption of the feedback mechanisms inhibiting the endogenous lipidic synthesis.

Revista Cubana de Farmacia , 2004,
Abstract: La población de la zona oriental de Cuba refiere los efectos beneficiosos del uso tradicional de la Cassia grandis L. en la anemia, con la utilización del polvo seco obtenido del fruto como un suplemento nutricional. El objetivo fue evaluar dicho efecto en un modelo experimental de anemia ferropénica en ratas, inducido por sucesivas extracciones de sangre y administración de una dieta carente de hierro. Todos los animales fueron sometidos durante 15 días a una dieta semisintética deficiente en hierro y a extracciones de sangre 3 veces por semana hasta lograr concentraciones de hemoglobina en sangre menores de 9 g/dL. Se formaron 3 grupos y se mantuvo la misma dieta: grupo I sin suplementar, grupo II suplementado con 15 mg de hierro/kg de dieta y grupo III la misma cantidad de hierro más 750 mg/kg de peso corporal de polvo seco de Cassia grandis L. durante otros 15 días. Al finalizar se determinaron las concentraciones de hierro, hemoglobina y hematócrito en sangre. Las concentraciones medias de hemoglobina al cabo de los 15 días de tratamiento fueron significativamente diferentes en los 3 grupos experimentales, con resultados mayores en el grupo suplementado con hierro y Cassia grandis L.; también en este grupo se observó un incremento significativo de los valores medios de hierro en plasma en relación con los valores obtenidos en los animales no suplementados y en los animales que recibieron solamente hierro en la dieta. El porcentaje de hematócrito no mostró diferencia significativa entre tratamiento. Los resultados corroboran el uso popular y tradicional de la Cassia grandis L. en los estados anémicos, al mejorar la utilización del hiero y la producción de hemoglobina. The population of the eastern zone of Cuba refers to the benefitial effects of the traditional use of Cassia grandis L. in anemia by using dry powder obtained from the fruit as a nutritional supplement. The objective was to evaluate this effect in an experimental model of iron-deficiency anemia in rats, induced by successive blood extractions and the administration of an iron-lacking diet. All the animals were on a semisynthetic iron-deficiency diet and blood was extracted 3 times a week until attaining haemoglobin concentrations in blood under 9 g/dL. They were divided into 3 groups on the same diet: group I with no supplement, group II supplemented with 15 mg of iron/kg of diet, and group III the same amount of iron plus 750 mg/kg of body weight of dry powder of Cassia grandis L. for other15 days. At the end, the concentrations of iron, hemoglobin and hematocrit in blood were determi

Abstract: Los ancianos que reciben tratamiento de hemodiálisis crónica han aumentado en la actualidad y esta población es especialmente susceptible a varios problemas, entre ellos la malnutrición, que en hemodiálisis se asocia a una mayor morbimortalidad. La evaluación del estado de nutricional es especialmente importante para las enfermeras de diálisis. Objetivo y ámbito: Conocer el estado de salud y la situación metabólico-nutricional, basados en parámetros antropométricos, de los pacientes mayores de 65 a os incluidos en tratamiento de hemodiálisis crónica en una Unidad de Diálisis, con especial referencia al riesgo de padecer desnutrición y conocer el grado de intervención actual sobre los pacientes desnutridos, indicando qué pacientes tienen un aporte suplementario. Dise o: Se trató de un estudio descriptivo transversal. Pacientes, material y métodos: Se estudiaron 22 pacientes (16 mujeres y 6 hombres), mayores de 65 a os que recibían tratamiento de hemodiálisis crónica en el primer trimestre de 2004. El estado nutricional se evaluó con medidas antropométricas, marcadores bioquímicos, marcadores dialíticos, test MNA de evaluación nutricional y encuestas dietéticas. Las medidas antropométricas fueron realizadas por personal entrenado y las medidas bioquímicas coincidieron con las extracciones mensuales de la unidad. Se clasificó el grado de desnutrición según los parámetros antropométricos PTC y CB. Resultados: Según el PTC, el 90,8% (n=20) de los pacientes padecían de desnutrición calórica (5 leve, 12 moderada, 3 grave) y según el CB, el 54,5% (n=12) de los pacientes tuvieron malnutrición proteica (7 leve, 5 grave). Los diabéticos presentaron mayor prevalencia de desnutrición calórica con un 66,66% (n=6). Un 54,5% (n=12) de los pacientes recibieron algún suplemento nutricional. Conclusiones: La malnutrición más frecuente en los pacientes estudiados es la calórica más que la proteica, siendo conveniente utilizar varios criterios (antropométrico, bioquímico o inmunológico) para establecer el diagnóstico de una desnutrición, siendo un gran aliado los parámetros antropométricos y el tratamiento con suplementos nutricionales en la práctica habitual para mantener el estado nutricional y minimizar la morbimortalidad en los pacientes desnutridos. The elderly population who received hemodialysis treatment has increased in the actually and this population is especially susceptible to have several problems like malnutrition who is associated with higher morbid-mortality in hemodialysis treatment. The evaluation of the nutritional state is especially important for dialys

Health (Health) , 2013, DOI: 10.4236/health.2013.512A015
Abstract:

The purpose was to examine and compare the psychometric properties of a Mexican Spanish version of the WHOQOL-OLD module. The instrument was applied to 285 individuals aged over 60 years (mean = 69.26, SD = 6.52). All participants completed a demographic data sheet, the WHOQOL-OLD, the Beck Depression Inventory (BDI), and the Geriatric Depression Scale (GDS); 182 of the 285 participants also completed a quality of life questionnaire for diabetic patients (DQOL). Acceptable levels of reliability were found, with Cronbach’s alpha values between 0.70 and 0.90 for overall quality of life and all domains except for autonomy, where the alpha value was low. The exploratory factor analysis carried out to examine the construct validity of the instrument yielded six domains: sensory abilities, autonomy, past/present/future activities, social participation, death and dying, and intimacy (explained variance of 62.95%). The mean overall quality of life score was 94.86 (SD = 13.68, range 50 to 120). The WHOQOL-OLD module showed criterion validity and concurrent validity with respect to the BDI (r = -0.516, p = 0.034), the GDS (r = -0.336, p = 0.002), and the DQOL (n = 182, r = 0.159, p = 0.032). Discriminant validity was also confirmed with respect to self-perceived health (t = 2.701, d.f. = 225, p = 0.007) and education (F(3, 280) = 9.015, p < 0.001), for both overall quality of life and some of its dimensions, but this was not the case with respect to gender (t = 1.292, d.f. = 283, p > 0.05). We conclude that the Mexican Spanish version of the WHOQOL-OLD module has adequate psychometric properties.

Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.43027
Abstract:

The quality of life (QOL) appears as an object of study of psychology, as a central component of human well-being. The quality of life in the elderly is especially relevant because as the years go the older persons can have lost health, the social role, the cognitive functioning, the power financial and their family. The purpose of the study is to evaluate the impact of psychological variables associated with quality of life in Mexican elderly. A sample of 75 elderly people between 60 and 87 years (mean = 65, SD = 9.41), 45 women and 30 men, assigned to a health clinic. QOL was measured with the WHOQOL, and an ex post facto design, three groups were formed by the level obtained with depressive symptoms GDS: (G1) absent (n1 = 42), (G2) mild (n2 = 19) and (G3) moderate-severe (n3 = 14). An acceptable correlation between QOL and spirituality (r = .523, p < .0001). A negative association between QOL and depression (r = .482, p < .0001). The QOL showed differences between groups with different levels of depressive symptoms (F(2.72) = 15.212, p < .0001). The QOL exhibited differences between diseased subjects (QOL = 61.19) and nondiseased (QOL = 66.61) (t = 2.025, p < .046). There were differences in the level of spirituality (Sp) among elderly patients (Sp = 64.77) and non-elderly patients (Sp = 75.0) (t = 2.37, df = 97, p < .02). The QOL in the elderly can be improved with psychological interventions to help reduce depression, where spirituality can be a resource and coping strategy to strengthen other areas of aging.
