[Clinical study on niaodujing in treating chronic renal failure]

One hundred and five chronic renal failure patients were divided randomly into two groups, 75 cases of Niaodujing (NDJ) treatment group and 30 cases of control group treated with aldehyde coated oxystarch. The effects were compared between two groups and within the same group before and after the entry. Results indicated that the total effective rate and markely effecive rate of NDJ group (74.1% and 44.0%) were better than those of the control group (56.6% and 23.3%) respectively (P < 0.05). The serum creatinine, blood urea nitrogen and middle molecular substance were decreased and creatinine clearance rate was increased significantly after NDJ treatment as compared with before treatment (P < 0.05-0.01). In comparison of two groups, the decrement of creatinine clearance rate and middle molecular substance and the increment of creatinine in NDJ group were higher than that in control group (P < 0.05-0.01). NDJ was especially effective in patients with azotemia or early renal failure.
