Vitex doniana is traditionally used in Togo to treat various diseases including wounds. The aim of this work was to evaluate the efficiency of Vitex doniana on cutaneous wound healing. Wounds were induced in ICR mice divided into four groups as following: Group I received carbopol 974P NF empty gel, Groups II and III were treated topically with carbopol gel containing 2.5% and 5% of Vitex donia...
The nitrogen species available in the growth medium are key factors determining expression of xyl genes for biodegradation of aromatic compounds by Pseudomonas putida. Nitrogen compounds are frequently amended to promote degradation at polluted sites, but it remains unknown how regulation observed in the test tube is propagated into actual catabolism of, e.g. m-xylene in soil, the natural habit...
Physical properties of interfacial layers formed at the xylene-water interface by the adsorption of a polyaromatic organic compound, N-(1-hexylheptyl)-N'-(5-carbonylicpentyl) perylene-3,4,9,10-tetracarboxylic bisimide (in brief, C5Pe), were studied systematically. The deprotonation of the carboxylic group of C5Pe at alkaline pH made it highly interfacially active, significantly reducing the xyl...
Background and Objective: Currently, photocatalysts have become a major focus of research in physics, chemistry, and surface engineering. It is hoped that this science help to solve various environmental problems. This study investigated the effect of ultraviolet lamp type on the removal efficiency of xylene utilizing the fixation of TiO2 nanoparticles on the activated carbon absorber and pass...
Background and Objectives: Today, given the numerous complications caused by use of chemical drugs, attention has been paid to the use of herbal medicines. The purpose of this study was to investigate the antinociceptive and anti-inflammatory effects of hydroalcoholic extract of female cones of Juniper and Plantago ovata in male Wistar rats. Methods: In this study, 144 male Wistar rats were ...
Exposure to vapours of volatile chemicals is a major occupational and environmental health concern. Toxicity testing of volatile organic compounds (VOCs) has always faced significant technological problems due to their high volatility and/or low solubility. The aim of this study was to develop a practical and reproducible in vitro exposure technique for toxicity testing of VOCs. Standard test a...
Introduction: Volatile organic compounds such as xylene are one of the main air pollutants. Adsorption method are of the most common methods used in the control of volatile organic compounds. The aim of this study was to investigate the xylene removal from air through nano activated carbon adsorbent in comparison with NIOSH approved carbon adsorbent. Material and Method: Xylene adsorption...
Background: Clearing is an important step in the preparation of histological sections, that removes alcohol and other dehydrants from tissues prior to infiltration of the embedding material (usually paraffin wax).Different types of clearing agents are chloroform, Xylene, Toluene, Paraffin, Methyl benzoate and methyl salicylate & Citrus fruit oils.The commonly used clearing agent is xylene that ...
Background: Bovine mastitis is one of the most relevant and problematic diseases to treat and control in practice. Puxing Yinyang San (PYS) is a compound of herbs to treat bovine mastitis in China. This study was performed to evaluate the analgesic and anti-inflammatory activities of PYS in mice and rats. Materials and Methods: The analgesic and anti-inflammatory activities of PYS were determin...
