RESUMO
Moringa oleifera (MO) is a native tree of Asia and is cultivated in some areas of Mexico as part of traditional horticulture. The aim of the present study was to compare the efficacy of MO infusion vs. MO ethanolic extract for the simultaneous treatment of nonalcoholic fatty liver (NAFLD), hyperlipidemia, and hyperglycemia in a murine model fed with a high-fat diet (HFD). BALB/c mice were fed a balanced diet (healthy control) or an HFD for 6 months. With this, the NAFLD model was established before starting a therapeutic intervention with MO for two months. The phytochemical analysis by nuclear magnetic resonance in 1H and 13C experiments showed signals for pyrrole alkaloids and triterpenes as the main constituents of the extract and infusion preparation. A significant reduction of SGPT, SGOT, lipids, urea, and glucose in blood among NAFLD groups treated with MO (infusion or extract) was found, when compared to the NAFLD-placebo group. Steatosis and liver inflammation were found to be decreased in the MO groups, as infusion or ethanolic extract. Infusion produced a better therapeutic effect than the extract in all parameters, except glycemic control, where the extract was better. As an additional finding, it is noteworthy that treatment with MO, particularly through infusion, resulted in improved motor activity. Moreover, a reduction in anxiety-like behavior was observed exclusively with the administration of infusion. These observations provide valuable insights into the potential broader effects of Moringa oleifera beyond the primary aim of the study.
RESUMO
The obesity worldwide has produced an increase in obesity-related diseases and can be associated with low concentrations of 25-hydroxyvitamin-D. Also obesity and low physical activity can decrease sun exposure, so the aim was to correlate vitamin D intake with serum 25-hydroxyvitamin-D levels and to assess sun exposure habits in schoolchildren with obesity. Materials and methods. A correlational study was performed from January 2017 to January 2018 on 103 children between 6-12 years of age, with a body mass index ≥+2SD for age and sex, according to the World Health Organization. Blood samples were taken to determine the serum concentrations of 25-hydroxyvitamin-D, a nutritional survey to determine the vitamin D intake and a sun exposure questionnaire were applied. A Spearman correlation coefficient analysis was performed. Results. Forty-seven percent of the children were girls. The median years of age was 10. The median serum 25-hydroxyvitamin-D levels were 35.5 ng/mL, 74.8% had sufficient levels, 25.2% had insufficient levels. The median vitamin D intake was 214.7IU in boys and 231.9IU in girls. Regarding sun exposure, most of the children had excessive levels of sun exposure and inadequate sun protection practices. A positive correlation between vitamin D intake and serum 25-hydroxyvitamin-D was identified only in boys (rho=0.276, p=0.041). Conclusion. A positive correlation between vitamin D intake and serum 25-hydroxyvitamin-D levels was found in obese boys and excessive levels of sun exposure with inadequate sun protection practices in boys and girls(AU)
La obesidad se le ha asociado con distintas comorbilidades, bajas concentraciones séricas de 25-hidroxivitamina-D, sedentarismo que a su vez podría comprometer la exposición solar; por tanto, el objetivo fue relacionar la ingesta de vitamina D con los niveles séricos de 25-hidroxivitamina-D y determinar los hábitos de exposición solar en escolares con obesidad. Materiales y métodos. Estudio correlacional realizado de enero 2017 a enero 2018, en 103 niños entre 6 y 12 años, con un índice de masa corporal ≥+2DE para edad y sexo, según la Organización Mundial de la Salud. Se extrajo muestras sanguíneas para determinar las concentraciones séricas de 25-hidroxivitamina-D, se aplicó una encuesta nutricional para determinar la ingesta de vitamina D y un cuestionario de exposición solar. Se realizó un análisis del coeficiente de correlación de Spearman. Resultados. El 47% de los sujetos eran niñas. La mediana de edad fue de 10. La mediana de los niveles séricos de 25-hidroxivitamina-D fue de 35,5 ng/mL, el 74,8% tenía niveles suficientes, el 25,2% tenía niveles insuficientes. La mediana de la ingesta de vitamina D fue de 214,7UI en niños y de 231,9UI en niñas. Con respecto a la exposición solar, la mayoría de los niños presentaban una exposición excesiva y prácticas inadecuadas de protección solar. Se identificó una correlación positiva entre la ingesta de vitamina D y la 25-hidroxivitamina-D sérica en los niños (rho=0,276, p=0,041). Conclusión. Se identificó una correlación positiva entre la ingesta de vitamina D y los niveles séricos de 25-hidroxivitamina-D en niños obesos y exposición excesiva con prácticas inadecuadas de protección solar en niños y niñas(AU)
