This review article summarises and discusses a wide collection of studies published over the last 40 years reporting on the effects of OPs on the liver, in an attempt to propose general mechanisms of OP hepatotoxicity and possible treatment. Several key biological processes have been reported as involved in OP-induced hepatotoxicity such as disturbances in the antioxidant defence system, oxidative stress, apoptosis, and mitochondrial and microsomal metabolism. Most studies show that antioxidants can attenuate oxidative stress and the consequent changes in liver function. However, few studies have examined the relationship between OP structures and the severity and mechanism of their action. We hope that future in vitro, in vivo, and clinical trials will answer the remaining questions about the mechanisms of OP hepatotoxicity and its management. -

Spectrophotometric Determination of Thiocyanate In
Investigative Forensic Sciences © All rights are reserved by Buddha D. Paul and Thomas Research Article Open Access Spectrophotometric Determination of Thiocyanate in Human Saliva by a Unique Iodine-Azide-Chromogenic Substrate Reaction and its Application in Distinguishing Tobacco Smokers from Non-Smokers† Buddha D. Paul and Thomas Bosy Division of Forensic Toxicology, Office of the Armed Forces Medical Examiner, Dover AFB, Delaware, USA. Abstract A method to detect thiocyanate (SCN) in human saliva is presented. Thiocyanate concentrations appear to be diagnostic when classifying smokers or non-smokers, and in determining some clinical conditions. The method involves the reaction of SCN with excess iodine and azide, and spectroscopic detection of unreacted iodine by a chromogenic substrate, ABTS. The calibration was linear over the range of 12.5-150 µmol/L (slope = 0.0086 delta-Abs/SCN µmol/L, intercept = -0.0160 delta-Abs, R2 0.9998). The method was applied to analyze 29 saliva specimens. The results were similar to those obtained from a gas chromatography-mass 2 spectrometry method (slope = 0.9595, R 0.9790). Based on Grubbs equation applied to specimens from non-smoking subjects, a threshold concentration of 1100 µmol/L for SCN was determined to distinguish smokers from the non-smokers. The SCN concentrations in 18 out of 20 saliva specimens collected from 2 smokers were above this threshold. The specimens from smokers were also examined for nicotine and cotinine by a GCMS method. While nicotine concentrations were found to vary, the cotinine concentrations remained stable, 134+29 ng/mL. Generally, the presence of nicotine/cotinine in specimens only indicates exposure to tobacco products, but the presence of any of these compounds with elevated SCN, is an indication of smoking. -

Organophosphate Poisoning : a Review
120 Sinha and Sharma Med J Indones Organophosphate poisoning : A review Parmod K. Sinha, Ashok Sharma Abstrak Pestisida organofosfat digunakan secara luas di seluruh dunia. Keracunan oleh bahan ini merupakan masalah kesehatan masyarakat, terutama di negara berkembang. Zat neurotoksik organofosfat merupakan bahan yang dianggap mengancam dalam bidang militer dan terorisme. Mekanisme toksisitas bahan ini adalah dengan cara menghambat asetilkolinesterase yang mengakibatkan menumpuknya neurotransmitor asetilkolin dan terjadi rangsangan terus-menerus pada reseptor asetilkolin pada sistem saraf sentral maupun perifer. Selain krisis kolinergik, organofosfat dapat menimbulkan berbagai sindrom neurologis, baik akut maupun kronik. Sedangkan gejala peralihan ( intermediate) terjadi 1-4 hari setelah krisis kolinergik teratasi. Pengobatan standar terdiri dari reaktivasi asetilkolinesterase dengan antidot golongan oksim (prolidoksim, oksidoksime, HI-6 dan HLo7), dan pengendalian efek biokimia asetilkolin dengan menggunakan atropin. Golongan oksim yang baru HI-6 dan Hlo7 merupakan reaktivator asetilkolinesterase yang lebih cocok dan efektif untuk keracunan akut dan berat dibandingkan dengan prolidoksim dan obidoksim. Penderita yang mendapat pengobatan segera, biasanya dapat sembuh dari toksisitas akut, namun gejala neurologis ikutan dapat saja terjadi. (Med J Indones 2003; 12: 120-6) Abstract Organophosphate pesticides are used extensively worldwide, and poisoning by these agents, particularly in developing nations is a public health problem.
