Effect of Bimin Decoction on Aquaporin 5 in Nasal Mucosa of Allergic Rhinitis Rats with Lung and Spleen Qi Deficiency Syndrome Via NF-κB Signaling Pathway
To observe the effect of Bimin decoction(BMD) on nuclear factor-kappa B(NF-
κ
B) signaling pathway and aquaporin 5(AQP5) expression in allergic rhinitis (AR) rats with lung and spleen Qi deficiency syndrome(LSQDS)
in order to study the mechanism in treating AR.
Method:
2
Fifty-six SD rats were randomly divided into seven groups: control group
AR group
LSQDS AR group
BMD low dose two weeks group and four weeks group
BMD high dose two weeks group and four weeks group. The control group did not intervened
the AR group established the AR disease model with ovalbumin (OVA) as the allergen
the other five groups established the LSDQS model with smoke and senna gavage
and also established the AR disease model with OVA sensitization at the same time as the AR group. After the model was established successfully
four BMD intervention groups were separately given low dose BMD (11.3 g·kg
-1
) for 2 weeks and 4 weeks
and high dose BMD (22.6 g·kg
-1
) for 2 weeks and 4 weeks. To observe the general situation of the rats
hematoxylin eosin (HE) staining was used to observe the pathological changes of the nasal mucosa
immunohistochemistry and Western blot were used to detect the expression levels of NF-
κ
B and AQP5
real-time fluorescent quantitative polymerase chain reaction technique (Real-time PCR)was used to detect mRNA levels of interleukin-1
β
(IL-1
β
)
tumor necrosis factor-
α
(TNF-
α
)
interleukin-6 (IL-6).
Result:
2
The typical AR symptoms were found in AR rats
the AR symptoms and lung and spleen Qi deficiency symptoms were found in AR rats with LSQDS at the same time
and the AR symptoms and lung and spleen Qi deficiency symptoms were significantly improved after the intervention of BMD. Compared with the control group
the typical histopathological changes of nasal mucosa were found in AR group and LSQDS AR group
with a higher behavioral score (
P
<
0.05)
and the expression of NF-
κ
B and AQP5 protein increased (
P
<
0.05)
the expression of IL-1
β
TNF-
α
IL-6 and AQP5 mRNA increased (
P
<
0.05). Compared with AR group
the pathological changes of nasal mucosa in LSQDS AR group were more serious
and the expression of NF-
κ
B protein in nucleus increased (
P
<
0.05)
the expression of TNF-
α
and AQP5 mRNA increased (
P
<
0.05). Compared with LSQDS AR group
the pathological changes of nasal mucosa in the groups which interfered by BMD were improved
and the expression of NF-
κ
B and AQP5 protein decreased (
P
<
0.05)
the expression of IL-1
β
TNF-
α
IL-6 and AQP5 mRNA decreased (
P
<
0.05). Compared with BMD low-dose two-week group
the expression of NF-
κ
B protein in nucleus decreased (
P
<
0.05) in BMD high dose four week group.
Conclusion:
2
Compared with AR group
the AR condition of the rats with LSQDS is more serious under the same allergen stimulation
BMD can treat AR and reduce the over secretion of glands
which may be related to inhibit the expression of AQP5 by inhibiting the NF-
κ
B signaling pathway.
