ABSTRACT
<p><b>OBJECTIVE</b>To study the therapeutic efficacy and mechanism of oxime drug, pralidoxime chloride (PAM-Cl), on acute dichlorvos (DDV) poisoning.</p><p><b>METHODS</b>The toxic signs and survival rate were recorded and ChE activity in blood was determined in treatment group with PAM-Cl and non-treatment group after DDV was given to rats and mice by gastrogavage; the therapeutic efficacy and reactivation of DDV-inhibited ChE by PAM-Cl were observed on the patients with acute DDV poisoning.</p><p><b>RESULTS</b>(1) The alleviated and delayed toxic signs as well as higher survival rate were found in PAM-Cl treatment group compared with non-treatment group. (2) After the rats were exposed to DDV, the ChE activities of whole blood in different time within 24 h were statistically significantly higher in PAM-Cl treatment group than in non-treatment group (P < 0.05). (3) After PAM-Cl treatment, muscular fasciculation and other nicotinic signs in poisoned patients were disappeared and the inhibited blood ChE activities were gradually reactivated to normal level.</p><p><b>CONCLUSION</b>PAM-Cl has therapeutic efficacy against acute toxicity of DDV through its reactivation of inhibited ChE.</p>
