Regulatory Effect of Modified Erchentang on Levels of Lymphokines Relating to Th1,Th2 and Th9 Cells and Expressions of IL-4R1/IL-13RA1 in Bronchioles of Rats with Chronic Obstructive Pulmonary Disease
To study the effect of modified Erchentang on levels of interleukin-12 (IL-12)
interferon-
γ
(IFN-
γ
)
interleukin-9 (IL-9)
interleukin-4 (IL-4) and interleukin-13 (IL-13) in plasma and bronchoalveolar lavage fluid (BALF) of all rats
as well as expressions of interleukin-4 (IL-4) receptor (IL-4R1) and interleukin-13 (IL-13) receptor (IL-13RA1) in bronchioles tissue of rats with chronic obstructive pulmonary disease (COPD).
Method
2
Fifty SD rats were randomly divided into 5 groups
namely normal group
model group
and low
middle and high-dose modified Erchentang groups (5
10
20 g·kg
-1
)
with 10 rats in each group. COPD in rat was prepared by using cigarette smoke combined with dripping lipopolysaccharide (LPS) in trachea. After the modeling
normal and model groups were given normal saline solution through intragastric (
ig
) administration
while other groups were given corresponding herbal drugs (5
10
20 g·kg
-1
) intragastrically (
ig
) for 14 days. The levels of IL-12
IFN-
γ
IL-9
IL-4 and IL-13 in plasma and BALF were detected by Enzyme-linked immunosorbent assay (ELISA) method, and immunohistochemistry (IHC) method was used to detect the expressions of IL-4R1 and IL-13RA1 in bronchioles tissue of all of the groups.
Result
2
Compared with the normal group
the levels of IL-12 and IFN-
γ
were decreased significantly (
P
<
0.01)
but the levels of IL-9
IL-4 and IL-13 in plasma and BALF were significantly increased (
P
<
0.01)
and the expressions of IL-4R1 and IL-13RA1 in bronchioles tissue were increased significantly (
P
<
0.01) in model group. Compared with the model group
the levels of IL-12 and IFN-
γ
were increased significantly
while the levels of IL-9
IL-4 and IL-13 in plasma and BALF were decreased significantly (
P
<
0.01)
and the expressions of IL-4R1 and IL-13RA1 in bronchioles tissue were decreased significantly (
P
<
0.01) in modified Erchentang groups (10
20 g·kg
-1
).
Conclusion
2
Modified Erchentang has effects in resisting inflammatory and protecting tissue structure of bronchioles. Its mechanism may be correlated with increasing the levels of IL-12
IFN-
γ
and reducing the levels of IL-9
IL-4 and IL-13 in plasma and BALF
and inhibiting the expressions of IL-4R1 and IL-13RA1 in bronchioles tissue.
