BACKGROUND:Penehyclidine is a newly developed anticholinergic agent.We aimed to investigate the role of penehyclidine in acute organophosphorus pesticide poisoning(OP)patients.METHODS:We searched the Pubmed,Cochrane library,EMBASE,Chinese National Knowledge Infrastructure(CNKI),Chinese Biomedical literature(CBM)and Wanfang databases.Randomized controlled trials(RCTs)recruiting acute OP patients were identifi ed for meta-analysis.Main outcomes included cure rate,mortality rate,time to atropinization,time to 60%normal acetylcholinesterase(AchE)level,rate of intermediate syndrome(IMS)and rate of adverse drug reactions(ADR).RESULTS:Sixteen RCTs involving 1,334 patients were identifi ed.Compared with the atropineor penehyclidine-alone groups,atropine combined with penehyclidine significantly increased the cure rate(penehyclidine+atropine vs.atropine,0.97 vs.0.86,RR 1.13,95%CI[1.07–1.19];penehyclidine+atropine vs.penehyclidine,0.93 vs.0.80,RR 1.08,95%CI[1.01–1.15])and reduced the mortality rate(penehyclidine+atropine vs.atropine,0.015 vs.0.11,RR 0.17,95%CI[0.06–0.49];penehyclidine+atropine vs.penehyclidine,0.13 vs.0.08,RR 0.23,95%CI[0.04–1.28]).Atropine combined with penehyclidine in OP patients also helped reduce the time to atropinization and AchE recovery,the rate of IMS and the rate of ADR.Compared with a single dose of atropine,a single dose of penehyclidine also signifi cantly elevated the cure rate,reduced times to atropinization,AchE recovery,and rate of IMS.CONCLUSION:Atropine combined with penehyclidine benefi ts OP patients by enhancing the cure rate,mortality rate,time to atropinization,AchE recovery,IMS rate,total ADR and duration of hospitalization.Penehyclidine combined with atropine is likely a better initial therapy for OP patients than atropine alone. 展开更多

In last few decades there is exponential increase in use of organophosphorus (OP) compounds as pesticides and insecticides leading to adverse effect on human population and live stock. There is a great need to develop portable analytical tools that are amenable for remediation and bioremediation process monitoring, where rapid analysis of large number of samples is essential. Determination of various organophosphorus compounds has been achieved by integrating biocomponents with different transducers. The close integration of the biological events with the generation of a signal offers the potential for fabricating compact and easy-to-use analytical tools of high sensitivity and specificity. With the availability of new materials, associated with new sensing techniques has led to remarkable innovations in the design and construction of organophosphorus biosensors. The present review describes the specifications of most of the electrochemical Organophosphorus biosensors reported till date. 展开更多

Spraying of organophosphorus insecticides (OPI) using high volume technique may result in poisoning cases among farmers or inhabitants in the spraying zone. This study reported a case among farmers in Gaza Strip, Palestine and discussed the follow up treatments. Results showed sever fasciculation of tongue and all muscle, pinpoint pupils not reacting to light, losing consciousness and disoriented, irritability, followed by diarrhea, vomiting, and severe inhibition of acetyl choline esterase (ACHE). Irritability and low level of ACHE activity were the unique syndromes of this case. Management of the poisoning with Atropine injection was not successful treatment to cure the case. Treatment with Toxogonin as intravenous injection resulted in relieved the irritability of the poisoned case and cure the patient at the end point. During the six weeks of follow up period, the case was severely poisoned in the 1st week, moderate poisoned in the 2nd week and slightly poisoned at the 3rd week. A medical decision to release the patient was made after ACHE activity level reached 4750 U/L, which very close to the normal range. The farmers left the hospital after three weeks of medical treatments and follow up. It is recommended to use Toxogonin in the management of poisoned cases with OPI immediately on arrival of cases with losing consciousness. 展开更多

In this paper,we compared the sensitivities of AFEST(a thermophilic esterase from the archaea Archaeoglobus fulgidus) and acetylcholinesterase(AChE) towards five organophosphorus compounds(OPs) by means of molecular docking,and found that only the docking energy between AFEST and dichlorvos is lower than that between AChE and dichlorvos.Via the docking model of AFEST and dichlorvos,Arg43 was found to play an important role in the interaction between AFEST and dichlorvos by means of stabilizing the complex.Then mutant R43S was constructed,the IC 50(the concentration required to reduce virus-induced cytopathicity by 50% is estimated as 50% inhibitory concentration) of which to dichlorvos was lower than that of the wild type AFEST by a factor of 1.56,indicating the enhanced sensitivity of mutant R43S to dichlorvos.Combining of theory with experiment,we have obtained important structure-function information of AFEST,which will be helpful to the further studies of esterase. 展开更多
