Protective effect of ganoderan on renal damage in rats with chronic glomerulonephritis

Abstract

Purpose: To investigate the protective effect of ganoderan on renal damage in rat models with chronic glomerulonephritis induced by adriamycin. Methods: 48 healthy Sprague-Dawley rats were randomly divided into three groups: control, nephritic model and ganoderan treatment groups. Changes of the following indices in the three groups were observed 6 weeks after treatment: 24-hour urine protein, albumen, serum creatinine, cholesterol. Histopathological observations of the renal cortex were made by light and electron microscopy. Results: Compared with controls, levels of 24-hour urine protein (9.60±0.57mg/d vs. 82.50±3.18mg/d), serum creatinine (35.25±2.63μmol/L vs. 44.75±8.06μmol/L) and cholesterol (1.15±0.10mmol/L vs. 4.02±0.25mmol/L) of rats in the nephritic model group were increased (P<0.05), and the concentration of albumen was decreased (35.98±1.34g/ L vs. 19.05±0.62g/L, P<0.05). Ganoderan administration decreased 24-hour urine protein (82.50±3.18mg/d vs. 45.01±3.94mg/d, P<0.05). Following ganoderan, the pathological changes in kidney tissue were improved compared with those in the nephritic model group. Conclusion: Ganoderan exerts protective effects in rats with chronic glomerulonephritis induced by ADR. Ganoderan reduced 24-hour urine protein, serum creatinine, cholesterol, improving renal function and reducing the severity of renal injury. © 2008 CIM.
