Objective To explore the roles of tetramethylpyrazine (TMP) in the prevention of simulated high altitude acute lung injury(ALI) in dogs. Methods A total of 21 dogs were randomly divided into ALI, treatment and control groups in a simulated altitude of 4 000 m. All animals were sacrificed at 6 h after exposure to the altitude . Results TMP could inhibit the decrease of the peripheral WBC count and alleviate the infiltration of inflammatory cells in lungs and pulmonary edema. No marked improvement of the decreased level of arterial PaO2 was found. Conclusion TMP can partially improve acute lung injury due to fat embolism.
