Abstract:
Objective Few reports are seen about the effects of cooling blood and removing stasis on nephrin and podocin . This study was to evaluate the therapy of cooling blood and removing stasis for Henoch -Sch?nlein purpura nephritis ( HSPN) and its ac-tion mechanisms by observing the effects of Danshao Granular Ⅲ on hematuresis , proteinuria and the expressions of nephridial nephrin and podocin in HSPN rats . Methods Twenty-one SD male rats were e-qually randomized to a blank control , an HSPN model , and a Dan-shao group.At 13 weeks after modeling , the animals in the model group were treated intragastrically with distilled water , while those in the Danshao group with Danshao Granular Ⅲtwice daily for 4 weeks. Then, the urinary red blood cell ( RBC) count was examined , the
24 h urinary protein quantity determined , the glomerular mesangial changes observed under the light microscope , the protein expres-sions and distributions of nephrin and podocin detected by indirect immunofluorescence , and their mRNA expressions determined by re-al-time PCR. Results The urinary RBC count and 24 h urine protein quantity were significantly higher in the HSPN model than in the blank control group (26.5/HP vs 0.3/HP and [2.214 ±1.090]g/24 h vs [0.624 ±0.354]g/24 h, both P<0.01).The model rats showed obvious pathological changes in the renal tissue .The urinary RBC count and 24 h urine protein volume were remarkably de-creased in the Danshao group as compared with the models (0.8/HP vs 26.5/HP and [1.000 ±0.651]g/24 h vs [2.214 ±1.090] g/24 h, both P<0.01).The pathological changes in the renal tissue of the Danshao group were reduced in comparison with those of the model group.The protein expression of nephrin was higher in the former than in the latter (65.975 ±14.414 vs 43.520 ±0.632, P<0.01) and so was that of podocin though with no statistically significant difference (P>0.05).The distributions of nephrin and podocin were improved after Danshao treatment .The mRNA expressions of nephrin and podocin were markedly higher in the Danshao group than in the HSPN models (0.530 ±0.089 vs 0.117 ±0.021 and 0.490 ±0.160 vs 0.033 ±0.025, P<0.05). Conclusion Danshao Granular Ⅲ, with its main action mechanisms of cooling blood and removing stasis , can effectively reduce urinary RBC count and urinary protein quantity and improve the symptoms of HSPN in rats .
