LPS诱导的肺损伤模型

实验方案：

1. 小鼠适应性生长后随机分组；

2. 地塞米松作为阳性对照药， LPS滴鼻刺激前半小时和后6小时给药；

3. LPS刺激24小时后处死小鼠，收集肺泡灌洗液和肺；

4. 检测灌洗液细胞因子以及细胞侵润情况；

5. 肺做病理检测；

Brief protocol of LPS induced lung injury

1. After one week acclimation, mice will be randomly divided into several groups;

2. DEX will be used as ref cpd. 3 mpk DEX will be administrated 0.5h prior LPS challenge and 6h post LPS challenge;

3. 24h post LPS challenge, mice will be sacrificed, followed by BAL fluid and lung tissue collection;

4. cytokine and cell infiltration in BALF will be measured accordingly;

5. Lung will be used as Histopathology analysis.
