The results showed:(1) MP polymerase chain reaction test showed positive results in the bronchoalveolar lavage fluid from all of the MP-infected rats (infectious group, n=4), while they were all negative in BALF from the control group (n=4,P＜0.05) and from those rats both infected with MP and, at the same time, treated with erythromycin (treating group n=4,P＜0.05). Bacterial cultures of the bronchial and lung tissue were negative in all three groups. Using transmission electron microscope the widened interalveolar septa with increased amount of collagen were found in the infectious group, while there were no obvious abnormalities in the other two groups.

Results:The following phenomena were observed:the Ph, PaO2 of the model rabbits descended sharply, the PaCO2 increased lightly, the HR slowed down obviously, but the BR increased, the SBP and DBP of the model rabbits descended markedly, and the PS content decreased dramatically. The pneumonic pathology changes showed pneumorrhagia, atelectasis, shrink of alveolus and pulmonary hyaline membrane. The above results indicated that it accorded with the standard of I-type of acute respiratory distress syndrome.

Methods: Twenty-four rabbits were randomly divided into three groups:① the control group(group C, n=8): received sternotomy only and no ischemia;② the ischemia/reperfusion group(group I/R, n=8): the left lungs of rabbits were rendered ischemia by ligating the left pulmonary hili for 60 minutes followed by 60 minutes reperfusion;③ the edaravone group(group E, n=8): the left lungs were rendered ischemia for 60 minutes followed by 60 minutes reperfusion, and 10 mg/kg edaravone was administered intravenously 5 minutes prior to ischemia. Blood MDA and SOD were measured. Protein concentrations, WBC count, and PMN percentage in broncho-alveolar lavage fluid were determined. Samples of left lung tissue were sent for determining the left lung dry-to-wet weight ratio and evaluating the pathologic changes.

Fiberoptic brochoscope is a useful instrument to diagnose lung cancer. Bronchial lavages using fiberoptic bronchoscope could not only improve the diagnosis of lung cancer, but also cost little. In addition, bronchial lavages, called"fluid biopsy", is helpful to diagnose primary of secondary carcinoma locating in respiratory tract, including peripheral lung cancer, bronchioalveolar carcinoma, pulmonary metastatic carcinoma and lymphoma.
