Abstract:Objective To compare the protective effects of different processes of Qikui Particles for model rats with diabetic nephropathy. Methods Fifty-four healthy SD rats (male, 8 weeks old) were selected. The model rats with diabetic nephropathy were induced by high sugar/fat diet + unilateral nephritic ligation + Streptozotocin (STZ, 40 mg/kg, ip). After successful establishment of model rats, they were divided into 5 groups: model group, Irbesartan group, process 1 (water boiled concentrated decoction) group, process 2 (water boiled and alcohol extraction concentration) group, process 3 (the mixed of above two processes) group, and the blank group was set up. Qikui Particles prepared under 3 different processes were orally administered at the same dose (18.67 g/kg ) for 5 consecutive weeks. The effects of different processes of Qikui Particles on blood sugar, urinary protein, creatinine and endogenous creatinine clearance rate in rats with diabetic nephropathy were observed, and histopathology was detected. Results Compared with blank group, the body weight in model group was decreased significantly (P < 0.01), the food-intake, water consumption and urine volume were increased (P < 0.05 or P < 0.01), the blood sugar was improved significantly (P < 0.01). After drug intervention, compared with model group, the body weight in each drug administration group was increased more or less, the food-intake, water consumption and urine volume were decreased more or less; the blood sugar in process 2 group and process 3 group was decreased significantly (P < 0.05); the serum creatinine in Irbesartan group and process 3 group was decreased significantly (P < 0.05 or P < 0.01); the endogenous creatinine clearance rate in each drug administration group was increased significantly (P < 0.05 or P < 0.01); the urinary protein excretion rate in Irbesartan group and process 2, 3 group was decreased significantly (P < 0.01 or P < 0.05). The results of histopathology showed that the main performance of kidney in model groups was glomerular hypertrophy, tubular dilation, interstitial and renal pelvis focal infiltration of inflammatory cells; compared with model group, the scope and extent of renal injury were reduced slightly in each drug administration group, especially in Irbesartan group and process 2 group. Conclusion The protective effects of different processes of Qikui Particles for diabetic nephropathy are related to the decrease of blood sugar, creatinine, urinary protein and alleviation of renal injury, especially in process 2 group and process 3 group.
