ABSTRACT

Objective@#To investigate a mass incident of bromadiolone poisoning and analyze related clinical data.@*Methods@#An investigation was performed for a mass incident of bromadiolone poisoning in a place in Shandong, China in December 2015, and related clinical data were analyzed and summarized.@*Results@#This incident was a mass incident of bromadiolone poisoning caused by spreading poison. The poisoned patients had major clinical manifestations of bleeding and coagulation disorder and all of them were cured after comprehensive rescue, especially after intravenous drip of vitamin K1.@*Conclusion@#Bromadiolone poisoning can cause severe visceral hemorrhage and coagulation disorder, and intravenous drip of vitamin K1 has a good therapeutic effect.

ABSTRACT

Objective@#To study the therapy of cordyceps-astragalus-salvia miltiorrhiza in treating acute lung injury and pulmonary interstitial fibrosis induced by paraquat poisoning.@*Methods@#All 120 adult Wister male rats were randomly assigned to three groups, the paraquat poisoning group (rats were intragastric administration paraquat 50 mg/kg body weight once at the beginning) , the cordyceps-astragalus-salvia miltiorrhiza therapy group (rats were given cordyceps-astragalus-salvia miltiorrhiza 90 mg/kg body weight intragastric administration half an hour after paraquat was given, then the same dose was given once a day) ; control group (rats were intragastric administration with physiological saline) . At 7th, 14th, 21st, and 28th day rats were sacrificed postanesthetic respectively after paraquat exposure, sample of lung tissue, bronchoalveolar lavage (BAL) , and venous blood were collected. GSH, SOD, TNF-α, TGF-β1, and HYP in plasma, bronchoalveolar lavage (BAL) , and the lung homogenates were determined. Optical microscope was performed to examine pathological changes in lung.@*Results@#Each experimental time point paraquat group and the treatment group rats serum SOD content significantly lower than the control group (P<0.05) . Each experimental time point the treatment group rats serum SOD levels increased significantly than that of paraquat group (P<0.05) . Each experimental time point paraquat group rats serum GSH content significantly lower than that of the control group (P<0.05) . Treatment group rats 7 days time GSH content significantly lower than that of the control group (P<0.05) . Treatment group 21 days, 28 days GSH content was increased significantly than that of the paraquat group (P<0.05) . Each experimental time point paraquat group rats alveolar lavage SOD content was significantly lower than that of the control group (P<0.05) . Treatment group 7 days, 14 days time SOD content was significantly lower than that of the control group (P<0.05) , Treatment group 21 days, 28 days SOD content was increased significantly than that of the paraquat group (P<0.05) . Each experimental time point paraquat group and the treatment group rats alveolar lavage GSH content significantly were lower than that of the control group (P<0.05) . Treatment group days 14 and 21 days, 28 days GSH content was increased significantly than that of the paraquat group (P<0.05) . Each experimental time point paraquat group rats alveolar lavage TNF α levels was higher than that of the control group (P<0.05) . Treatment group 7 days, 14 days the rat alveolar lavage TNF α levels was higher than that of the control group (P<0.05) . Treatment group 21 days, 28 days TNF α content significantly was decreased than that of paraquat group (P<0.05) . Paraquat group days 14 and 21 days, 28 days HYP content was significantly higher than that of control group (P<0.05) . Treatment group 21 days HYP content was significantly higher than that of control group (P<0.05) . Treatment group 28 days time HYP content in lung tissue of rats was significantly decreased than that of the paraquat group (P<0.05) . Each experimental time point paraquat group rat lung tissue (tissue homogenate) TGF-β1 content was higher than that of the control group, the difference was statistically significant (P<0.05) . Under optical microscope, the tissue damage of lung was aggravated, and reduced after cordyceps-astragalus-salvia miltiorrhiza was administrated.@*Conclusion@#Cordyceps-astragalus-salvia miltiorrhiza can reduce inflammation factor releasing, and relieve lung injury. It has therapeutic effect on lung injury induced by paraquat poisoning.
