Abstract:
Objective: To investigate the effect of nitric oxide synthase（NOS） inhibitors and Larginine（LArg） on the prognosis of traumatic shock in rats. Methods:Traumatic shock models of SpragueDaulay rats were made and randomly devided into control group (n=24)，LNAME treatment group (n=24)，AG treatment group (n=24) and LArg treatment group (n=24). Serum nitric oxide(NO) levels and oxygen partial pressure in tissues include skeletal muscles，liver and small intestine were detected at 1h，3h，5h after resuscitation. Meanwhile，hemodynamic data of the rats and their survival rates of 12h and 24h were monitored and recorded. Results:Serum NO concentration was statistically lower after resuscitation in LNAME group than that in control group, while there were no statistical significance of tissues oxygen partial pressure and survival rate in 12、24h between the two groups. AG could decrease serum NO levels only at late stage of traumatic shock，but no effect on the synthesis and relase of NO at early stage of traumati shock.AG could improve tissues oxygen partial pressure of the liver and small intestine, and prolonged the mean survival time. LArg could increase serum NO levels, and improve oxygen partial pressure of intestine and significantly increase the survival rate at 12h and 24h in rats with traumatic shock. Conclusions:Treatment with AG and LArg can improve the prognosis of traumatic shock rats much better than that with LNAME.
