Abstract:
Objective To explore the changes of blood 8-iso-Prostaglandin F_(2a)(8-iso-PGF_(2a))content in different time after building-model and study its significance,and study the intervention effect of N-acetylcysteine(NAC) on it.Methods Seven-day-old Sprague-Dawley (SD) rats were randomly divided into 3 groups:intervention,operation and false operation groups.rats in intervention group were administered with NAC 0.1 mg/(g?d),Rats in operation group were given an equal volume of normal saline,and rats in false group operation had no administration.The blood was obtained to determine serum of 8-iso-PGF_(2a) content in 30 minutes,on the first,third,seventh and twenty first day after the building-model,respectively.EIA assay method was used to determine serum 8-(iso-PGF)_(2a) content.Results Serum 8-iso-PGF_(2a) concentration in rats from operation group,intervention and false operation groups were(168.7?(24.2)),(120.9?23.4) and (50.0?8.8) ng/L within 30 minutes after the building-model, respectively.There were a remarkable difference between serum 8-iso-PGF_(2a) concentration in three groups(P0.05).Conclusions The concentration of serum 8-iso-PGF_(2a) of rats rises remarkably early after building-model, and the peak concentration appears at 30 minutes after the building-model. NAC can effectively decrease serum 8-iso-PGF_(2a) content, which suggest that there is large value of clinical administration.
