ABSTRACT
Acute organophosphorus pesticide poisoning (AOPP) is one of the common critical diseases.In order to improve the rate of clinical cure, in recent years, many new treatment methods in clinical are recognized.In this paper, we will make a overview from the mechanism of AOPP, the application of classical drug cholinesterase reactivators, anticholinergicdrugs, other new applications such as fat emulsion for AOPP and blood purification therapy, combination therapy of Chinese and Western medicine, comprehensively elaborate the application of these drugs and treatment methods in clinical and therapeutic effect.
ABSTRACT
AIM: There has been accumulating evidence demonstrating that activators for peroxisome proliferator-activated receptor ? (PPAR?) have antiinflammatory, antiatherogenic, and vasodilatory actions. We investigated the effect of PPAR? activator, fenofibrate, on trombin-induced endothelin-1 (ET-1) expression in cultured vascular endothelial cells. METHODS: Bovine aortic endothelial cells (BAECs) were treated with the PPAR? activator, fenofibrate. The ET-1 concentrations were evaluated by radioimmunoassay. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the ET-1 mRNA expression. RESULTS: Thrombin(10U/L) induced ET-1 release in BAECs [(22.4?4.7) nmol/g protein vs control (13.2?1.6) nmol/g protein, P
ABSTRACT
AIM: We hypothesized that PPAR? ligands stimulate endothelial-derived nitric oxide(NO) release to protect the vascular wall.Thus,the purpose of this study is to investigate the effects of ciglitazone(Cig) and fenofibrate(Fen) on angiotensin Ⅱ(AngⅡ)-induced decrease in endothelial NO synthase(eNOS) expression and NO production in human umbilical vein endothelial cells(HUVECs).METHODS: HUVECs were preincubated for 24 h with Cig(10~(-7), 10~(-6),10~(-5),10~(-4) mol/L) or Fen(10~(-5) and 10~(-4) mol/L),then incubated for 12 h with 10~(-7) mol/L AngⅡ.Total RNA was extracted,and the expression of mRNA and protein of eNOS was assessed by RT-PCR and Western blotting.NO production was measured by Griees method.RESULTS: In the presence of 10~(-7) mol/L AngⅡ for 12 h,NO production in cultured HUVECs was decreased(P
