Renal function-related biochemistry indexes in each group of rats. (a) Serum creatinine level. (b) Urea nitrogen level, and (c) Urinary protein excretion rate. The UUO model was established by ligating the rats’ left ureters with 4-0 silk thread, and on the postoperative day of UUO, animals were administered with verbascoside by intragastrical gavage for two weeks. Values are represented as means ± standard error (SD); n=6 or 7 rats per group. Mann-Whitney U test was used for two-group comparisons of Serum creatinine, and two-tailed student’sStudent’s t-test was used for single two-sample comparisons of Ureaurea nitrogen and Urinaryurinary protein excretion raterates. Verb: verbascoside. *P<0.05; **P<0.01
