Are the Therapeutic Effects of Huangqi (Astragalus membranaceus) on Diabetic Nephropathy Correlated with Its Regulation of Macrophage iNOS Activity?
Table 1
Mogensen’s criteria for stages of DN [
1].
| Stage | Features |
| I | Hyperfunction, hypertrophy. | Increased urinary albumin excretion (microalbuminuria). | II | Morphologic lesions without clinical signs of disease. Increased GFR. | Poor diabetic control or exercise increase microalbuminuria. | III | Incipient DN. Persistent proteinuria (30–300) mg/24 h. Microalbuminuria slowly increasing over the years. Increased GFR. | IV | Overt DN. Persistent proteinuria (>0.5 g/24 h). Untreated hypertension leads to decreased GFR. | V | End-stage renal failure with uremia due to DN. |
