The aims of this study were to explore the effects of Astragaloside IV on diabetic nephropathy (DN) rats. A total of 38 male Sprague-Dawley (SD) rats were divided into three groups: 10 in the normal (control) group, 14 in the DN model group, and 14 in the AS-IV group. Treatment began one week after the streptozotocin DN model was successfully established. Blood glucose and urine micro-albumin levels were measured every four weeks. After being treated for 12 weeks, all SD rats were sacrificed for blood and renal specimen collection.
Albuminuria is an independent predictor of renal and cardiovascular complications in hypertensive subjects. We previously showed that lectin-like oxidized low-density lipoprotein receptor 1 (OLR-1) polymorphisms at G501C are associated with susceptibility to essential hypertension and serum C-reactive protein levels. We have now investigated a possible association between OLR-1 polymorphisms at G501C, genotyped by PCR-RFLP, and severity of albuminuria in 307 hypertensive Chinese subjects and 225 age- and gender-matched controls.
