ABSTRACT

The objective of this study was to evaluate the potential of n-butanol extract obtained from flowers of Chrysanthemum fontanesii (Cf) and vitamin E against kidney oxidant injury induced by sodium valproate in mice. The evaluation was made through Histopathological examination and measuring kidney lipid peroxidation (LPO) and antioxidant parameters: reduced glutathione (GSH), glutathione peroxidase (GPx) and catalase. Severe alterations in all biomarkers were observed after injury with VPA. Treatment with Cf extract and vitamin E resulted in markedly decreased levels of LPO while increased levels of GSH and antioxidant enzymes activities were observed. In conclusion, n-butanol extract of Cf may be an interesting candidate for the treatment of kidney injury induced by VPA through enhancing endogenous antioxidant defenses and normalizing the kidney histopathological architecture.

ABSTRACT

Aim To investigate the renoprotective effect of berberine in diabetic nephropathy rat model. Methods The rat model of DN was induced by intra-peritoneal injection of streptozotocin ( STZ ) after fed with high sugar and high fat diet for six weeks. The rats were divided into 5 groups randomly, i. e. normal control group, model group, BBR ( 50 mg · kg-1 ) , BBR ( 100 mg · kg-1 ) and BBR ( 200 mg · kg-1 ) treatment group. The fasting blood glucose ( FBG) was evaluated at 2, 4, 6,8 week respectively. The patho-logical changes in the kidney were determined by PAS staining. The expression of vascular endothelial growth factor ( VEGF) was detected by immunohistochemistry and Western blot respectively. Results Compared with normal control group, the value of FBG, SCr, BUN and UTP of model group were sharply increased. Compared with model group, the value of FBG in ber-berine different dosage treatment groups were signifi-cantly decreased to various degrees, and berberine dif-ferent dosage treatment could decrease the levels of SCr, BUN and UTP in different degree. Berberine could surpress the alterations of pathological changes in the kidneys and downregulate the expression levels of VEGF in the kidney of diabetic rats with nephropathy. Conclusion Berberine could significantly ameliorate the biochemical indicators and renal injury of the model rats through affecting the abnormal expression levels of VEGF in the kidney.

ABSTRACT

Objective To investigate effective dosage of ACEI in renoprotective effect in primary glomerular dieases.Method In 154 patients with primary glomerular diseases,we performed a 4 month therapy,including 40 cases with high or low doses of captopril and 51 cases with high or low doses of cilazapril and 45 cases with high low doses of enalapril,and 18 cases with amlodipine as control.Mean arterial pressure (MAP),uninary protein,urinary albumin excretion rate and renal function were measured at basis and after 1,2,3,4 month of therapy,and ACE gene polymorphism was determined in these patients.Result 1.There were no difference on ACE gene polymorphism and diet protein and diet salt among control group and different ACEIs group;2.The antiproteinuria and the effect on renal function were same between patients with high and low dose of different ACEIs.Conclusion The low dose of ACEI has the same renoprotective effect as general dose in primary glomerular diseases.
