Résumé
To explore the relationship between pathological findings and clinical manifestation, pathological and clinical data were collected and analyzed in 22 cases died from infantial pneumonia, and inference study were undertaken based on the theory of airway hydrokinetics (AHK).The results showed that all 22 cases suffered from airway obstruction. 2 of 5 cases with aspiration pneumonia were confirmed to have inhaled meconium, other 3 cases were probably correlated to gastro-esophageal reflux (GER).Among 17 cases with primary pneumonia, myocardial damage was observed in 14 cases, cerebral neural degeneration in 10,hepatic damage in 13 and renal damage in 9, respectively. Pathological changes were significantly correlated with the results of X-rays and blood-gas analysis.It is concluded that big changes of AHK can be induced by pneumonia, and should be pay attention to the features of the laminar flow and the eddy flow in the airway during the clinical treatment of infantial pneumonia.
Résumé
AIM: To study the role of the gene and protein expression of MIP-1? and RANTES in the bronchus of murine asthma. METHODS: 20 male BALB/C mice were randomly divided into two groups: the control group (A 0 group) and asthma group (B 0 group). In the experiment, the mice model of asthma was established by the ovalbumin (OVA) challenge methods. The protein expression of MIP-1? and RANTES were detected by immunohistochemistry methods. The gene expressions of MIP-1? and RANTES were detected by in situ hybridization methods. RESULTS: Immunohistochemistry showed that the expressions of MIP-1? protein and RANTES protein around the bronchus of group B 0 were significantly higher than those of group A 0 (P
