Abstract:
The changes of mean pulmonary arterial pressure (PAP) and 6-keto-PGF1a and TXB2 in the plasma and lung tissues of 3 groups of dogs (7 in each group) with blast injury (group Ⅰ),high velocity shell fragment injury on one of the extremities (group Ⅱ),and combined injury of the both (group Ⅲ) were investigated.It was found that PAP and TXB2 in the plasma and lung tissues increased after all the 3 kinds of injuries.The changes of PAP was most marked in group Ⅰ while those of TXB2 was more marked in groups Ⅲ and Ⅲ than in group Ⅰ.6-kcto-PGF1a increased in the plasma and lung tissues after blast and shell fragment injury but decreased in the plasma and showed no changes in the lung tissues after combined injury.The significance of these changes of 6-keto-PGF1a and TXB2 in the 3 kinds of injuryies were discussed.
