ABSTRACT

Objective To investigate the changes in ATPase activity of diaphragm in rats with acute organophosphorus poisoning (AOPP) and to explore the effect of Xuebijing injection on the ATPase activity. Methods 24 clean healthy Spraue-Dawley(SD)rats were divided into control group,model group and Xuebijing treatment group by means of random number table,with 8 rats in each group. AOPP model was established by intra-gastrical administration of 50 mg/kg oxide dimethoate. In Xuebijing treatment group,after oxide dimethoate administration,intraperitoneal injection of Xuebijing(10 mL/kg)was given at the same time,while in control group and model group,equal amount of normal saline(NS)was injected via the same route. The rats were sacrificed at 6 hours after model formation,and their diaphragms were taken sterilely. The activities of Na+-K+-ATPase and Ca2+-ATPsae of diaphragms were detected by enzyme linked immunosorbent assay(ELISA). The histopathological changes in diaphragms of rats were observed with light microscopy. Results 6 hours after intoxication,the diaphragm Na+-K+-ATPase activity of rats in model group was markedly lower than that in control group(mmol?h-1?g-1:5.22±0.74 vs. 9.98±0.37,P<0.01),while the Na+-K+-ATPase activity in Xuebijing treatment group(6.93±1.14) was markedly higher than that in model group(P<0.05). The diaphragm Ca2+-ATPase activity of rats in model group was markedly lower than that in control group(mmol?h-1?g-1:7.45±0.74 vs. 12.08±0.74,P<0.01),while the Ca2+-ATPase activity in Xuebijing treatment group(9.35±1.67)was obviously higher than that in model group(P<0.05)after intoxication for 6 hours. Light microscope observation indicated that there were swelling and necrosis in diaphragm in model group,while in Xuebijing treatment group no necrosis was found. Conclusion The diaphragm was degenerated and necrotic in AOPP rats,Xuebijing injection can lessen the injury in such rats,and the curative effect may be related to the improvement of the Na+-K+-ATPase and Ca2+-ATPsae activities of diaphragm.

ABSTRACT

Objective To discuss the correlations between hemoperfusion(HP) times and therapeutic effects/prognosis in patients with severe acute organophosphorus poisoning(AOPP). Methods According to the frequency of HP,82 patients with severe AOPP were divided into three groups:non HP(25 cases),HP1(27 cases) and HP2(30 cases)groups. The non HP group received only routine treatment,on the basis of routine treatment,the HP1 group accepted once HP within 12 hours after poisoning and the HP2 group underwent twice or more times of HP,the interval between each time being 24 hours. The comparisions of clinical indexes,incidences of complications and rates of mortality among the three groups were performed. Results With the increase of HP times,the dosages of atropine and pralidoxime chloride were significantly reduced,the times of serum cholinesterase(ChE)activity recovery,consciousness recovery,hospitalization and mechanical ventilation were significantly shortened,the score of acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score in 48 hours after admission,incidence of complications and mortality were evidently decreased(all P<0.05). Compared with those in HP1 group,the dosages of atropine(mg:164.57±68.82 vs. 256.81±97.06)and pralidoxime chloride(mg:6.95±1.40 vs. 8.76±1.64) in HP2 group were significantly reduced,the times of ChE activity recovery(day:9.03±2.46 vs. 10.96±3.44), consciousness recovery(hour:23.83±6.29 vs. 39.93±8.24),hospitalization(hour:9.57±2.39 vs. 11.52±3.02) and mechanical ventilation(hour:40.50±16.55 vs. 65.74±18.88)in HP2 group were significantly shortened;APACHEⅡscore during 48 hours after admission(11.97±3.47 vs. 14.26±2.88)was obviously decreased,and the incidences of complications,such as intermediate syndrome(10.0% vs. 18.5%),rebound phenomenon(3.3% vs. 25.9%),arrhythmia(13.3%vs. 44.4%),multiple organ dysfunction syndrome(MODS,6.7%vs. 29.6%)and mortality rate(6.7% vs. 18.5%)in HP2 group were markedly decreased(all P<0.05). Conclusion It is recommendable that combined with routine treatment,early and multiple HP application would enhance the therapeutic effect and decrease the mortality in patients with severe AOPP.

ABSTRACT

Objective In order to extrapolate the respiratory dysfunction of patients in early stage of acute organophosphorus pesticide poisoning (AOPP),transpulmonary thermodilution technique was used in swine models of severe acute dichlorvos poisoning (SADP) to evaluate respiratory function.Methods Twenty healthy female swine were randomly divided into dichlorvos ( n =7 ),atropine ( n =7 ) and control (n =6) groups.In the dichlorvos group,the swine were administered with 80% emulsified dichlorvos (100mg/kg) via the gastric tube toinduce SADP.In the atropine group,swinewere administered with dichlorvos,and 0.5h later,atropine was injected to obtain and maintain atropinization.The swine of control group were administered with saline solution instead.Arterial and venous blood samples were collected 0,0.5,1,2,4 and 6 hours after modeling for blood gas analysis and detecting acetylcholinesterase levels.Both extravascular lung water index (EVLWI) and pulmonary vascular permeability index ( PVPI ) were measured by using PiCCO (pulse indicator continuous cardiac output ). At the termination of the experiment,the animals were sacrificed and the lung wet/dry weight ratio was determined and histopathological changes of lung tissue were also observed under microscope.Results In the dichlorvos group,EVLWI and PVPI were substantially increased from 0.5 h to 6 h after modeling but PaO2/FiO2 decreased from 0-6 h after modeling.In the atropine group,EVLWI and PVPI increased initially,but then they decreased 1 h afterwards and PaO2/FiO2 was also gradually decreased from 0-1 h.In both dichlorvos group and atropine group,the EVLWI was negatively correlated with PO2/FiO2 and positively correlated with PVPI.Compared with the control group,the lung wet/dry weight ratio increased markedly in the dichlorvos group and mildly increased in the atropine group.Meanwhile,the histopathological changes of lung tissue were obvious in the dichlorvos group and mild in the atropine group.Conclusions SADP swine experienced substantial changes in respiratory function. EVLWI was a reliable and valuable indicator for evaluating respiratory function in the early stage of AOPP.

ABSTRACT

Objective To explore the therapeutic effect of lipid emulsion on acute organophosphorus poisoning and its consequence of acute lung injury. Methods A total of 48 sealant - grade Sprague-Dawley (SD) rats were randomly divided into four groups A,B,C,D,namely saline control group,lipid emulsion control group,the conventional therapy group and lipid emulsion administration group. After dichlorvos (DDVP) 11 mg/kg was given by intra-peritoneal injection,if there was no loss of DDVP during the injection process,the model of poisoning was considered to be made successfully.Then the rat models in four groups were respectively treated:with normal saline (5 ml/kg) intravenous injection in group A,lipid emulsion (5ml/kg) intravenous injection in group B,atropine (5 mg/kg) and pralidoxime chloride (40 mg/kg) intramuscular injection in group C,and combined use of lipid emulsion (5 ml/kg) with atropine and pralidoxime chloride in group D after administration of DDVP by intra-peritoneal injection.The activity of cholinesterase (CHE) in blood was detected before and 0.5 h,2 h and 4 h after DDVP poisoning. The clinical manifestations,the survival of rats,the wet weight of rat' s lung and the pathological changes of the lung tissue were observed within following 24 h. The rates of survival and symptoms of rats were compared between paired groups by using the x2 test,and the mean values of biomarkers were compared paired groups by using t test. Results In groups A and B,the intensity of muscular fasciculation and salivation were more severe and appeared sooner after DDVP exposure in comparison with groups C and D leading to lower survival rates in group A and B. Compared with group C,the rate of 24 h survival was higher and the intensity of muscular fasciculation was weaker in group D ( P < 0.05 ).In group A and group B,the 24-hour survival rates were 1/12 and 2/12,respectively ( P < 0.05 ).The levels of CHE in blood significantly decreased after DDVP poisoning ( P < 0.05 ).There was no significant difference in activity of CHE between group B and group A,and in groups C and D,the levels of CHE in blood were not significantly higher than that in the group B 0.5 h after DDVP poisoning ( P < O.05 ).In groups C and D,the activity of CHE in blood was significantly higher compared with group A and B,and that in group D was higher compared with C,and that in group B was higher compared with A 2 and 4 hours after DDVP poisoning ( P < 0.05 ).In groups C and D,the wet weight of rat lung was significantly lighter compared with groups A and B,and that in group D was lighter compared with C,and that in group B was lighter compared with A 24 h after DDVP poisoning P < 0.05 ).The electron microscopic findings showed the combined use of lipid emulsion with atropine and pralidoxime chloride obviously lessened the lung histopathologic changes after DDVP poisoning.Conclusions The lipid emulsion combined with atropine and pralidoxime chloride can be beneficial to controlling the toxic symptoms,reduce the death rate,accelerate the resume of the activity of CHE in blood,and relieve the lung injury induced by acute organophosphorus poisoning.

ABSTRACT

Objective To investigate the expression and clinical significance of early-stage serum interieukin-10 (IL-10) and tumor necrosis factor-α (TNF-α) in patients with acute organophosphorus pesticide poisoning (AOPP). Method 186 cases of AOPP were divided into mild group, moderate group and severe group according to the severity. 30 healthy volunteers served as control group. APACHE Ⅱ scores were evaluated for these patiences and their serum concentrations of IL-10 and TNF-α were detected by enzyme-linked immunosorbent assay (ELISA). Results APACHE Ⅱ scores increased significantly with the exacerbations of AOPP (P <0. 05). The serum IL-10 concentrations of AOPP was slightly higher than the control group. There was no significant difference compared with the control group (P >0. 05). APACHE Ⅱ scores positively correlated with the serum TNF-α concentrations, but not with the serum IL-10. However,the ratio of TNF-α and IL-10 positively correlated with APACHE Ⅱ scores ( P < 0. 01 ). Conclusions There were pro-inflammatory response and anti-inflammatory response in patients with AOPP. Overrelease of inflammation promoting factor and imbalance between inflammation promoting and inhibiting factors correlated with the severity of AOPP, which may be an important mechanism of multiple organ dysfunction syndrome of AOPP.

ABSTRACT

Objective To study the effect of oral administration of activated charcoal and mannitol on removing toxicant after acute organophosphorus pesticide poisoning (AOPP). Method A total of 41 patients with severe AOPP were randomly divided into experiment group (activated charcoal used as adsorbent and mannitol used as cathartics, n =21)and control group (without adsorbent and cathartics, n = 20). Patients of both groups received routine treatment for AOPP after admission to hospital. The differences in duration of atropinization, the length of hospitalization and the success rate of treatment were compared between two groups. Results There were significant differences in duration of atropinization, the success rate of treatment and hospitalization time between the two groups. Conclusions The combination of activated charcoal and mannitol is more effective than the conventional gastric lavage on removal of organophosphorus pesticides from G-I tract, shorting the duration of atropinization time and hospital stays, and enhancing the success rate of rescue as well as improving the outcome of patients after organophosphorus pesticide poisoning.

ABSTRACT

Objective To investigate the correlated clinical factors of upper gastrointestinal hemorrhage induced by acute organophosphorus pesticide poisoning(AOPP) and look for effective method for the prevention and treatment of upper gastrointestinal tract bleeding(UGTB).Methods 49 patients with severe AOPP were divided into UGTB group(group A,26 cases)and non-UGTB group(group B,23 cases).The time,frequency and causes of UGTB were observed.We also observed the differences in acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ),blood glucose and cholinesterase in serum.Results The causes of UGTB induced by AOPP were poison damage of stomach mucous membrane,gastric lavage damage and irritability ulcer;APACHE Ⅱ scores of group A were more than those of group B obviously;the level of cholinesterase was lower in group A.Correlation analysis showed that the APACHE Ⅱ scores had positive correlation and the level of cholinesterase had negative correlation with UGTB induced by AOPP.Conclusion Both the APACHE Ⅱ scores and level of cholinesterase can reflect the UGTB induced by AOPP.Active treatment of the primary disease and stress status and often the operation of gastric lavage are important ways to prevent and treat UGTB induced by AOPP.
