Fifteen minutes after smoke inhalation injury in rabbits, an intravenous dose of ginsenosides or ketoprofenwas given to the animals respectively. 6 hours after medication, it was found that both the drugscould significantly alleviate the platelet aggregation, but only ginsenosides could alleviate theaugmentation of pulmonary vascular permeability and the pathological lesions in the trachea andlungs. In those rats injured by smoke inhalation, l hour after an intravenous dose of ginsenosides, theplasma PGI<sub>2</sub> level was elevated and TXA<sub>2</sub>/PGI<sub>2</sub> ratio decreased significantly.展开更多
