- Abstract: Objective In order to explore the preventive effect and potential mechanism of Dai medicine Shenyeshan leech on chronic renal failure(CRF).The rat model of chronic renal failure was induced and replicated by adenine,and the pharmacodynamics and mechanism of CRF prevention and treatment were discussed.Methods SD rats were randomly divided into normal group,model group,Yougui pill group,high-dose alcohol extract group,middle-dose group,low-dose group.Prophylactic administration was performed 5 days before modeling,and starting from the 6th day,rats in the model group and each administration group were given 1.0%adenine by gavage in the morning,and drug treatment was given in the afternoon for 15 days.24 hours after the last administration,urine specific gravity(SG)was determined by refraction method;urine creatinine(Ucr)and 24-hour proteinuria(PRO)were determined by biochemical analyzer;red blood cell count(RBC),platelet number(Plt)were determined by cell analyzer,hemoglobin(HGB),mean platelet volume(Mpv),mean corpuscular volume(Mcv).Enzyme-linked immunosorbent assay kits were used to determine blood urea nitrogen(BUN),serum creatinine(Scr)content and urinary α1-microglobulin(α1-MG),kidney injury molecule-1(KIM-1)expression.Hematoxylin-eosin staining was used to observe the pathological morphology of rat kidneys,and immunohistochemical staining was used to analyze the expression of aquaporin 2(AQP2),transforming growth factor-β1(TGF-β1),and hypoxia-inducible factor(HIF-1α)-related proteins.Results Compared with the model group,the rats were significantly improved in various symptoms such as lethargy,sluggish reaction,yellow and rough coat with falling off,and the pathological morphology of the kidneys after administration.Blood routine indexes RBC,HGB,Mpv,Mcv levels increased,Plt level decreased.The 24-hour total urine volume decreased significantly(P<0.05),and the SG in the low-dose group increased significantly(P<0.05).When URO=3.2 μmol·L-1,urinary PRO could be recovered to negative after drug treatment.The levels of renal function injury indexes BUN,α1-MG and KIM-1 were significantly decreased(P<0.05,P<0.01,P<0.001);the renal index and Ccr levels of the rats in the administration group were significantly improved(P<0.05,P<0.01).At the same time,the related AQP2,TGF-β1 and HIF-1α protein expressions were improved.To sum up,it can be seen that the leech of the kidney leaf mountain can improve the renal histopathology and various indicators of chronic renal failure rats,reduce the degree of renal injury and renal fibrosis,and has a positive effect on the prevention and treatment of CRF in rats.
