Intervention Effect of Bixie Fenqingwan on Hyperuricemia Rats by Regulating Urate Transporters
To study the intervention effect of Bixie Fenqingwan on hyperuricemia (HUA) rats by regulating urate transporters.
Method
2
Sixty healthy rats were randomly divided into normal, model, allopurinol (0.03 g·kg
-1
), and Bixie Fenqingwan low-, medium- and high-dose (0.8, 1.6, 3.2 g·kg
-1
) groups, 10 in each group. Except the normal group, the other rats were given potassium oxonate 1.5 g·kg
-1
and adenine 0.1 g·kg
-1
for 28 consecutive days to establish the HUA rat model, and rats with increased serum uric acid (SUA) were considered successfully modeled. After modeling, corresponding drugs were given to the groups, once per day. Urine and blood was collected after 24 h of the final administration. The levels of urine uric acid (UUA), SUA, blood urea nitrogen (BUN) and serum creatinine (SCr) were measured by enzymatic colorimetry. The rat kidneys were taken and weighed to calculate the kidney index. The pathological changes of kidney tissue were observed by haematoxylin-eosin (HE) staining. The protein and mRNA expressions of urate transporter 1 (URAT1), glucose transporter 9 (GLUT9), adenosine triphosphate-binding cassette transporter protein G2 (ABCG2), organic anion transporter 1 (OAT1) and organic anion 3 transporter (OAT3) in kidney tissue were detected by immunohistochemistry and real-time quantitative polymerase chain reaction (Real-time PCR), respectively.
Result
2
Compared with the conditions in the normal group, the kidney index, levels of SUA, BUN and SCr, and protein and mRNA expressions of URAT1 and GLUT9 in kidney tissue were increased (
P
<
0.05), while the UUA level and protein and mRNA expressions of OAT1, OAT3 and ABCG2 were decreased in the model group (
P
<
0.05). In addition, there was compensatory dilatation with urate crystals and protein casts in renal tubules in the model group. Compared with the model group, the intervention groups had lowered kidney index (
P
<
0.05), reduced levels of SUA, BUN and SCr (
P
<
0.05), down-regulated protein and mRNA expressions of URAT1 and GLUT9 (
P
<
0.05), elevated UUA level (
P
<
0.05) and up-regulated protein and mRNA expressions of OAT1, OAT3 and ABCG2 (
P
<
0.05), and the kidney tissue lesions were alleviated (
P
<
0.05).
Conclusion
2
Bixie Fenqingwan has intervention effect on HUA, and its mechanism may be related to regulating urate transporters.
