It is common practice to try to prevent intestinal absorption of ingested poisons. Controversy continues about the relative effectiveness of charcoal, ipecacuanha, and lavage in salicylate overdose,' but no study has yet compared all three methods. This study of simulated aspirin overdose in volunteers aimed to compare the effectiveness of gastric lavage, emesis induced by ipecacuanha, and acti...
A carbamazepine intoxication with suicide attempt is a relatively common clinical problem that presenting with coma, respiratory depression, arrhythmia, hemodynamic instability and even death. We report a case of severe carbamazepine poisoning that was successfully treated with one session charcoal hemoperfusion. On admission, the patient was comatose and required ventilator support. Hemoperfus...

Recent studies in theWestern United States have supported climate scenarios that predict a higher occurrence of large and severe wildfires. Knowledge of the severity is important to infer long-term biogeochemical, ecological, and societal impacts, but understanding the sensitivity of any severity mappingmethod to variations in soil type and increasing charcoal (char) cover is essential before w...
The adsorption of gold onto activated charcoal is most dependent on the concentration and character of the 'spectator' cations present in the adsorption medium. In the presence of calcium ions, gold is adsorbed as the calcium aurocyanide complex. The degree to which the aurocyanide complexes are adsorbed follows the series Ca> Mt:> H> Li> Na> K, calcium aurocyanide being the most stable complex...
Yuchanyan Cave in Daoxian County, Hunan Province (People's Republic of China), yielded fragmentary remains of 2 or more ceramic vessels, in addition to large amounts of ash, a rich animal bone assemblage, cobble and flake artifacts, bone tools, and shell tools. The artifacts indicate that the cave was a Late Paleolithic foragers' camp. Here we report on the radiocarbon ages of the sediments bas...
