    Abstract:
    OBJECTIVE: To observe the preventive and therapeutic effects of Yishen Huanji Decoction (YSHJD), a compound traditional Chinese herbal medicine, on military overtraining-induced kidney injury in a rat model. METHODS: Thirty SD rats were randomly divided into normal control group, untreated group and YSHJD-treated group. The military overtraining-induced kidney injury in rats was established by forcing to run on the treadmill for 8 weeks. The rats in YSHJD-treated group were administered with YSHJD at the same time. The 24-hour urines were collected every weekend for detecting the contents of urinary sediment, 24-hour urine total protein, 24-hour urine albumin and activity of N-acetyl-beta-D-glucosaminidase (NAG). The blood and renal tissues were collected after 8-week training, and the levels of serum urea nitrogen (BUN) and creatinine (SCr) were detected. Angiotensin II (Ang II) was detected by radioimmunoassay and activity of Na(+), K(+)-ATPase in kidney was analyzed by chemical colorimetric method. RESULTS: Compared with the normal control group, after 8-week training, the contents of 24-hour urine protein, activities of NAG in urine, and the levels of BUN and SCr in rats in the untreated group and YSHJD-treated group were obviously increased (P<0.05), and these parameters of the YSHJD-treated group were lower than those of the untreated group (P<0.05). The contents of Ang II in blood plasma and kidney of rats in the untreated group and YSHJD-treated group were higher than those of the normal control group (P<0.05), and had no statistical difference between the untreated group and YSHJD-treated group. Compared with the normal control group, the activity of Na(+), K(+)-ATPase in kidney of rats in the untreated group was obviously decreased (P<0.05), and had no statistical difference between the normal control group and YSHJD-treated group. CONCLUSION: YSHJD can protect against military overtraining-induced kidney injury in rats by decreasing the contents of 24-hour urine protein, BUN and SCr, and the activity of NAG, and increasing the activity of Na(+), K(+)-ATPase.
