An Experimential Study On Changes And Cilinical Significance Of IL-1β, AngⅡ, TXA₂ And PGI₂ In Plasma Of Rabbits With PTE Before And After Pulmonary Thrombolysis.

Backgroud and objectivePulmonary thromboembolism(PTE)is the most common category of the pulmonary embolism(PE)and clinically PTE is always the term stands for PE as most of all cases of PTE belong to PE. Researches of American epidemicology show that PTE is the third cause of human death. Cardiovascolar hospital of Chinese Medical and Science department has proved that 11% of all the PTE cases were located on the segamental or the upper broncus after they did 900 autopsies. In recent years as more attention was paid to PTE and the athophysiological and pathological developments were accelerated, the morality rose significantly. But, in China the misdiagnosis is very common and curtails the cure and the prognosis. The effective way to decrease the motality of PTE is to identify and dissolve the embolism in eary stage. Howerer, the immediate treatment of PE was inhibited for there is no effective diagnostic means. So it is necessary to search for a simple way to discern PTE and evaluate the effectiveness of the treatment. Many studies show that cytokines are involved in the process of PE. Some of the cytokines which could constrict vessels are...
