Review Article: Herbal Approach for Obesity Management

Obesity, a complex interplay between environmental and genetic factors and is associated with significant morbidity and mortality. Usage of herbs for the management of obesity in the recent times is attracting attention. A web and manual based literature survey was conducted to assess the amount of information available on the herbal products for weight management. Traditional literature, PubMed, Scopus, Google scholar databases were screened up to February 2012. The search words were “obesity', 'herbal medicine/products/extracts”, 'medicinal plants', 'traditional medicine', 'Ayurvedic medicine' without narrowing/limiting searching words or elements. Publications only with abstracts/full articles and books were reviewed in the search. Based on the available literature, for many of the herbal and weight loss products, there is little published information and there have been no clinical trials or the level of evidence is limited. Our literature survey also indicated that these herbal products fall under an acceptable level of evidence or with no scientific background at all, or they have a scientific rational but not to an acceptance level. Attempts were made in the review to define the features of possible herbal weight loss product. An ideal herbal anti obesity product should reduce the weight by 10% over placebo of treatment by showing an evidence of improvement of bio markers like blood pressure, lipids and glycemia without any side effects.

添加石灰及养护时间对蒙脱土物理性质的影响

一、前言已知石灰作为一种添加料,对细粒土的工程性质带来一些有益的变化。已发现用石灰处理后,土的塑性、胀缩潜能都减小,并改善了土的强度特性。石灰稳定土主要是通过阳离子交换、絮凝和团聚、凝硬及石灰的碳化反应来达到的。阳离子交换和絮凝—团聚反应很快发生并立即改善了土的性能。比较而言,凝硬反应则与时间有关,它在长时间内持续进行。这些反应本身包括土中的硅、铝同石灰相互之间的反应。
