ABSTRACT
Objective To investigate the effect of Hupo Xiaoshi granules on renal tissue pathological changes and IL-1β, TNF-α and IL-6 in blood of nephrolith model rats. Methods Sixty SD rats were divided into normal control group 10 rats with purified water by intragastric administration(IG),and model group 50 rats with ethylene glycol, calcium and vitamin D3 by IG for 4 weeks to get kidney stones animal models. The successful model rats were randomly divided into model control group, potassium citrate solution group, Hupo Xiaoshi granules low, middle and high dose group (3. 335,6. 670,13. 340 g ? kg-1 , respectively), 10 rats per group with the corresponding drugs. Four weeks later, rat's renal tissue sections were stained with hematoxylin and eosin, renal tissue changes of calcium stones and pathology were observed.Plasma concentrations of IL-1β, TNF-α and IL-6 were detected by ELISA. Results Compared with the model control group, no renal interstitial hemorrhage and a few or no visible renal tissue calcium crystal deposition in the low, middle and high dose Hupo Xiaoshi granules group. In the normal control group, model control group, potassium citrate solution group, and low, middle and high dose Hupo Xiaoshi granules group,the plasma concentrations of IL-1β were respectively(50.50±13.54),(104.00±24.13),(93.00±20.08),(77.00± 25.21),(71.30 ±26.60),(65.50±26.18) pg?mL-1 ,respectively;those of IL-6 were(570.10±119.74),(1 040.00±260.15), (861.40±130.04),(740.00± 161. 31),(680. 00 ± 239. 49),(640. 00 ± 238. 42) pg?mL-1 ,respectively;and TNF-α plasma concentrations were(470.30± 154. 63),(1 010. 00 ± 230. 94),(820. 00 ± 192. 12),(830. 50 ± 110. 01),(720. 00 ± 140. 28), (715.00±173.54) pg?mL-1 ,respectively. Compared with the model control group, the plasma concentrations of IL-1β, IL-6 , TNF-α of the low, middle and high dose Hupo Xiaoshi granules group were significantly decreased (P<0.05 or P<0.01). Conclusion Hupo Xiaoshi granules can inhibit renal tissue pathological changes of nephrolith model rats, inhibit calcium crystals stones deposition in renal tissue, and reduce blood levels of inflammatory cytokines.
