Solubilización in vitro del aceite de árbol de té y primeros resultados de su efecto antifúngico en onicomicosis

IntroductionOnychomycosis is the main cause of nail alteration. Hepatotoxicity, interference and low adherence to pharmacological treatment are associated. Therefore, our objective was to assess the in vitro effectiveness of tea tree essential oil (less harmful) against main causative agents of these infections.Material and methodsTrichophyton rubrum and Trichophyton mentagrophytes were isolated and inoculated at a concentration of 3x10⁵ CFU / mL in potato agar dextrose and tea tree essential oil at different concentrations to assess its effect by counting colony forming units and radial growth.ResultsTrichophyton rubrum growth inhibition was obtained at concentrations higher than 0.04% of the essential tea tree oil (p = 0.004). In the case of Trichophyton mentagrophytes, inhibition was obtained at 0.02% (p = 0.017), and even complete inhibition at a final concentration of the oil at 0.07%.ConclusionsTea tree essential oil inhibits the in vitro growth of the fungus and may be a less harmful alternative to the onychomycosis treatment.     

Beyond Food Promotion: A Systematic Review on the Influence of the Food Industry on Obesity-Related Dietary Behaviour among Children

An increased consumption of energy-dense, nutrient-poor food and beverages as a result of a changing obesogenic environment contributes substantially to the increasing prevalence of childhood overweight and obesity. This paper reviews the nature and extent of food industry influences which expose children to commercial influences and thus might affect unhealthy dietary behaviour and finally contributes to obesity. A systematic search of nine electronic databases (including PubMed, PsycINFO, EconLit) and reference lists of original studies and reviews using key search terms identified 1900 articles. Of these only thirty-six articles met the inclusion and quality criteria. A narrative synthesis of the reviewed studies revealed six key obesogenic environments by which the food industry possibly influences obesity-related dietary behaviours in young children. These were schools, retailers, mass media “television”, mass media “internet”, home and promotional campaigns. Identifying these obesogenic environments is critical for monitoring and controlling the food industry, the development of effective environmental-level interventions to prevent childhood overweight and obesity and to identify knowledge gaps to be addressed in future research to support informed decisions of policy makers.     

宝鸡市电焊工体质状况的调查分析

目的 了解宝鸡市电焊工的体质现状.方法 选择装备制造企业20～60岁的1 025名电焊工进行体质测试,采用文献资料法、数理统计法等方法进行分析.结果 男电焊工肺活量平均值为(3 457.78±538.67)ml.女子平均值为(2 820.56±546.86) ml,高于陕西省平均水平(P＜0.01).台阶指数男女分别为55.55和57.88,与陕西省调查结果相当.男女电焊工的左右手握力差别均较大(P＜0.01),与电焊工焊接时右手使用频繁有关.电焊工的闭眼单腿站立时间的短于全国城市体力组平均水平(P＜0.01),平衡能力和肌肉控制能力有所下降.结论 该市电焊工的总体体质水平偏低.     

DTF乳剂对茶叶氟固定效果初步研究

目的探讨DTF乳剂固定茶叶氟效果。方法将DTF乳剂涂于茶叶,观察其固定氟效果。结果茶叶中添加0.5%~10%固氟剂可固定21.1%~97.9%茶叶氟,茶叶色、味、pH、茶多酚含量无明显改变。结论DTF乳剂是一种有效茶叶氟固定剂。     

砖茶氟在大鼠体内24小时代谢实验观察

目的观察砖茶氟在大鼠体内24h吸收、分布及排泄的动态变化。方法将Wistar大鼠分为两组,用灌胃方法分别给予砖茶水和氟化钠(NaF),含氟均为300mg/L。在染氟后0.25、0.5、1、2、4、8、16、24h处死动物,取血、小肠、股骨、肌肉、心、肝、肺、脾、脑及肾,用氟离子选择电极法测定氟水平。结果两组大鼠骨氟最高,24h内呈现明显的蓄积作用,至24h时,砖茶组骨氟增加了约77mg/kg,NaF组骨氟增加了约70mg/kg,两组比较,NaF在大鼠体内的代谢速度较砖茶氟快,表现为在各组织中达到峰值的时间早,排泄的速度快,24h内在软组织中无蓄积作用。砖茶氟吸收、分布及排泄的速度均较NaF慢,在各组织器官中的浓度较NaF组稍高,除骨外,在小肠、心脏中也有轻微的蓄积作用。结论砖茶氟在大鼠体内24h代谢速度较NaF慢,且砖茶氟在多种组织中均似有蓄积作用。
