[Epidemiologic study of Organophosphate and Organochlorate pesticides poisoning in hospitalized patients in Khorramabad Shohada Ashayer hospital from Mars to August 2006]

Poisoning is one of the most common medical emergencies. Every year many people refer to emergency wards due to poisoning and some of them are treated and some die because of severe complications. Most patients who refer to emergency wards are those who commit intentionally to suicide. This study is conducted to determine the prevalence of poisoning with pesticide [organophosphate and organochlorine] in persons referred to Shohada Ashaier hospital of Khorramabad in the first six months in 2006. Required information of poisoned people with poisoning pesticide [organophosphate and organochlorine] were collected using questionnaires which were distributed among the subjects. In this study 153 patients including 118 patients who poisoned with organophosphate and 35 patents with organochlorine were studied. Most of the patients [34.6%] aged between 21-71 years including 57.5% female and 42.5% male and their education was about under secondary school, 91.5% of them attempted to suicided. The total mortality rate was 12 that 7 of them died by toxifications with organochlorine and 5 cases by organophosphate, which in turn was due to their respiratory complications like ARDS and aspiration pneumonia. Findings indicate that due to high prevalence and mortality of poisoning with pesticides, this problem should be taken into consideration

Removal of 5-amino-2-chlorotoluene-4-sulfonic and chlorhydric acids from wastewater by weakly basic resin: equilibrium and kinetics / 生物医学与环境科学（英文）

<p><b>OBJECTIVE</b>To study the adsorption of 5-Amino-2-chlorotoluene-4-sulfonic (CLT) and chlorhydric (HC1) acids from wastewater by weakly basic resin.</p><p><b>METHODS</b>The kinetics and isotherm were studied. Thermodynamic parameters for the adsorption of acids were calculated and discussed.</p><p><b>RESULTS</b>The adsorption of CLT and HC1 acids followed Langmuir isotherm and the first-order kinetics model.</p><p><b>CONCLUSION</b>The adsorptive affinity of the two acids on D301R is in the order of CLT acid > HCl acid. CLT and HCl acids can be separated.</p>

Conductance of acetylcholine halides and perchlorate in ethanol at 25

Conductance measurements for acetylcholine halides and perchlorate in ethanol were reported at 25C. The data were analyzed by the Fuoss- Onsager equation. The extent of ionic association was found to increase with the increase of the anion size and discussed in terms of the solvent separated-ion pair model

Chlorate metabolism by whole cells and membrane vesicles of Escherichia coli K-2.

Se siguio la reduccion del clorato por Escherichia coli K-12 mediante la utilizacion de clorato marcado 36 C1-, preparado por oxidacion anodica del ion cloruro. Las celulas redujeron el nitrato y el clorato a velocidades similares. Las vesiculas de membrana y las celulas no acumularon clorato ni sus productos de reduccion (C102-, C10-, C1). El bajo nivel de radioactividad enlazado a celulas o vesiculas puede ser atribuido principalmente a absorcion inespecifica. Estos resultados son discutidos en relacion con la localizacion del sitio enlazante del clorato (y el nitrato) sobre la nitrato reductasa membranal de E. coli
