A total of 36 healthy male SD rats were randomly assigned to three groups: control group, AN group and sulodexide treatment group. Rat models of AN were established by a single tail intravenous injection of adriamycin (6.5 mg/kg) in both AN group and sulodexide treatment group. Sulodexide (10 mg/kg) was administered the rats in the treatment group once daily by garage from the first day of model establishment until the 14th day or the 28th day. Samples of 24-h urine and renal cortex tissues were harvested at day 14, 28 after the model establishment. Excretion of 24-h urinary protein was measured by Coomassie brilliant blue method. The pathological changes in renal tissues were observed by light microscopy and electron microscopy respectively. Heparanase mRNA was detected by RT-PCR. Expressions of desmin, CD2AP and heparanase were determined by immunohistological staining. The results showed that the expressions of heparanase mRNA and protein were increased in the glomeruli of AN rats at day 14 and 28 after the model establishment, which was accompanied by the increased expression of desmin and CD2AP. The mRNA and protein expression of heparanase was decreased in the sulodexide-treated rats as compared with AN rats at day 14 and 28. And, the protein expression of desmin and CD2AP was reduced as with heparanase in the sulodexide-treated rats. Proteinuria and podocyte foot process effacement were alleviated in the AN rats after sulodexide treatment. There was a positive correlation between the expression of heparanase and the expression of desmin and CD2AP (as well as 24-h urinary protein excretion). It was concluded that increased heparanase is involved in podocyte injury. Sulodexide can maintain and restore podocyte morphology by inhibiting the expression of heparanase in AN.展开更多

Objective: We studied the efficacy of sulodexide compared to losartan in patients with primary GN. Design and Method: This was a prospective, open labelled, randomized control trial in patients with stable primary GN. Patients were randomized to receive either sulodexide or losartan to maximum tolerated doses for 12 weeks. Blood and urine investigations were measured at baseline and at 4-weekly intervals. Adverse effects were recorded. Results: 18 patients were recruited (10-sulodexide and 8-losartan). Their baseline characteristics were comparable. At end study, patients in both groups showed no significant reduction in proteinuria and there were no differences between groups at each visit. Nonetheless, there was a trend towards lower protein uria in the losartan but not in sulodexide group. There were no changes in the other parameters of renal function or of coagulation over time. No adverse events in particular clinical bleeding occurred. Conclusion: Sulodexide and losartan did not demonstrate any significant anti-proteinuric effect in primary GN. Nevertheless, there was a trend of better proteinuria reduction in losartan group. Furthermore, other renal parameters were not significantly affected by both drugs.展开更多

In the sulodexide group, there was an apparent prevention of cognitive and behavioural impairment (relative incidence: 2.02) compared with acenocoumarol group (relative incidence: 4.86). The favourable results in sulodexide group may be related to their pharmacodynamic actions of inhibition of PAI-1, which may interfere with the pathogenesis of Alzheimer’s disease, and to the role of glutathione and PAI-1 in the β-amyloid system in the brain.展开更多
