The effect of charcoal-drug ratio on the antidotal efficacy of oral activated charcoal was studied in six healthy volunteers in a randomized cross-over study and compared with the adsorption capacity of activated charcoal in vitro. Aminosalicylic acid (PAS) 1 g and 5 g were ingested on an empty stomach in 30 ml of water. Immediately afterwards the subjects ingested 50 g of activated charcoal in...

BACKGROUND Charcoal-burning, a new suicide method, emerged in Hong Kong during the latest economic recession. Within 2 months charcoal-burning had become the third most common suicide method. AIMS To examine the characteristics of suicides by charcoal-burning, and to delineate the pathways linking macro-level economic and social changes with the subjective experiences of those surviving a cha...

Fire suppression and changing climate have resulted in increased large wildfire frequency and severity in the western United States, causing carbon cycle impacts. Forest thinning and prescribed burning reduce high-severity fire risk, but require removal of biomass and emissions of carbon from burning. During each fire a fraction of the burning vegetation and soil organic matter is converted int...

We compared conventional charcoal separation of antibody-bound and free antigen with a novel method involving magnetizable particles containing charcoal. The magnetizable charcoal separation method was as effective as the conventional method for a wide range of radioimmunoassays, including those for several steroids and small polypeptide hormones. In a detailed comparison of conventional vs. ma...

The objective of this study was to investigate the effects of manufacturing conditions on the adsorption capacity of heavy metal ions by Makino bamboo charcoal. Results show that the specific surface area and iodine number of bamboo charcoal activated at 900 degrees C were larger than those of bamboo charcoal activated at 800 degrees C. The specific surface area of bamboo charcoal activated at ...
