结论
2
复肾功方可改善腺嘌呤所致CRF大鼠肾功能和肾脏的病理学改变,其机制可能与通过抑制ACE-AngⅡ-AT1R轴,同时促进ACE2-Ang(1-7)-MASR轴来延缓CRF的进展有关。
Objective
2
To study the effect of Fushengong prescreption on the regulation-antagonism effect of angiotensin converting enzyme-angiotensin Ⅱ-angiotensin Ⅱ 1 receptor (ACE-AngⅡ-AT1R) axis and angiotensin converting enzyme 2-angiotensin (1-7)-Mas receptor[ACE2-Ang(1-7)-MASR] axis of rats with chronic renal failure(CRF), and to explore its mechanism of delaying the development of CRF.
Method
2
The 65 male SD rats were randomly divided into normal group (
n
=10) and modeling group (
n
=55). The normal group was routinely reared, while the modeling group were administered by gavage with 0.25 g·kg
-1
d
-1
adenine suspension for 28 days. After the model was successfully established, the survival model rats were randomly divided into model group, benazepril group(0.01 g·kg
-1
·d
-1
)and low,medium and high dose of Fushengong prescreption groups (4,8,16 g·kg
-1
·d
-1
). The normal group and model group were administered the same volume of normal saline by gavage, lasted for 28 days. After the experiment, systolic blood pressure (SBP) and diastolic blood pressure (DBP) of caudal artery were measured, and 24-hour urine was collected to determine 24-hour urine protein (24 h U-pro). The content of serum creatinine(SCr) and blood urea nitrogen (BUN) in the serum were measured, the histological morphology was observed by hematoxylin eosin(HE)staining, and the degree of renal interstitial fibrosis was observed by Masson staining. Enzyme linked immunosorbent assay (ELISA) was used to determine the contents of AngⅡ, Ang (1-7) and Cystatin C (CysC) in serum and renal homogenate. The protein level of ACE, ACE2, AT1R and MASR were detected by Western blot. The expression of ACE and ACE2 protein in renal tissues were detected by immunohistochemistry.
Result
2
Compared with normal group, the expression levels of SCr, BUN and CysC in model group were significantly increased(
P
<
0.05), the content of AngⅡ in serum and kidney tissues were significantly increased, the content of Ang (1-7) were significantly decreased(
P
<
0.05), the expression of ACE and AT1R protein in renal tissues were significantly increased(
P
<
0.05), and the expression of ACE2 and MASR protein were significantly decreased(
P
<
0.05). Compared with model group and benazepril group, after the intervention with Fushengong prescreption, the serum SCr,BUN and CysC decreased(
P
<
0.05),the content of AngⅡ in serum and kidney tissues decreased significantly,Ang(1-7) increased significantly(
P
<
0.05), the expression of ACE and AT1R protein in renal tissues decreased significantly(
P
<
0.05), ACE2 and MASR protein increased significantly(
P
<
0.05). The high-dose Fushengong prescreption has the best effect. The high, medium and low-dose effects of Fushengong prescreption were dose-dependent.
Conclusion
2
Fushengong prescreption improved renal function and pathological change of kidney in adenine-induced rats with chronic renal failure. The mechanism may be related to the inhibition of ACE-AngⅡ-AT1R axis and promotion of ACE2-Ang(1-7)-MASR axis ,which leads to the delaying of the progression of chronic renal failure.
