Objective To study the effect of Tongsai Granule (Granule for Removing Obstruction) on the extracellular matrix (ECM) of lung tissue in the acute exacerbations of rats with Chronic Obstructive Pulmonary Disease (COPD). Methods The Wistar rats were randomized into 7 groups with 10 in each: Blank control group
stable stage model group
acute exacerbation model group
High dosage of Tongsai Granule group
Low dosage of Tongsai Granule group
Aminofilina control group
Tingbei Capsule control group. The COPD acute exacerbation models were developed by Pneumonia Klebsiella Bacillus nasal dropping. The blank control group and model groups were given normal saline and the other groups were given corresponding medicines by gavage
twice a day. The expression of PCⅢ
LN and HA in serum and bronchoalveolar lavage fluid (BALF) were monitored by radio-immunity (RI) method
and the changes in the extracellular matrix of lung tissues were detected by immunohistochemistry method. Results The expression of PCⅢ
LN and HA in serum and BALF in acute exacerbation model group was significantly higher than that of stable model group (P<0.01) and blank control group (P<0.01). The expression of PCⅢ
LN and HA of stable model group was significantly higher than that of the blank control group (P<0.01). The expression of PCⅢ
LN and HA of high dosage of Tongsai Granule group was significantly lower than that of acute exacerbation model group (P<0.05 and P<0.01). The image analysis showed that the expression of collagen Ⅰ
collagen Ⅲ
collagenⅣ
LN
TGF-β of lung tissue in all groups was significantly higher than that of the blank control group (P<0.01). The expression of collagen Ⅰ
collagen Ⅲ
collagenⅣ
LN
TGF-β of lung tissue in acute exacerbation model group
aminofilina control group and high dosage of Tongsai Granule group
and the expression of collagen Ⅰ
collagen Ⅲ and collagen Ⅳ of low dosage of Tongsai Granule were both significantly lower than those of acute exacerbation model group (P<0.01). Conclusion Tongsai Granule has the effect to restrain the degradation of ECM in acute exacerbation of COPD and to restrain the remodeling of air passage structure
the effect of high dosage of Tongsai Granule group is the most remarkable.
