title: [Regulatory effect of yijing fang on adenine-induced infertility in rat models: a pharmacodynamic study].
abstract: OBJECTIVE
  To investigate the regulatory effect of Yijing Fang (YJF) on adenine-induced infertility in rats with kidney deficiency.
  
  
  METHODS
  Sixty healthy Wistar male rats, aged 1.5 mo and weighing (180 +/- 10) g, were normally fed for a week, and then divided into five groups of equal number (blank control, infertile model, high-dose YJF, mid-dose YJF, and low-dose YJF) according to the body weight of the rats. The models were made by intragastric administration of 500 mg/ml adenine in gum arabic solution in the ratio of 1:10 at the dose of 1 ml per 100 g body weight per day for 10 days. YJF was given at 3.38 g, 1.69 g and 0.85 g per 100 g body weight per day to the rats in the high-, mid- and low-dose groups, respectively. After 48 days of treatment, we observed kidney deficiency-related changes in sperm concentration and motility, the levels of testosterone (T) and other hormones and the volumes of the testis, epididymis, seminal vesicle and prostate, and compared the indexes among different groups.
  
  
  RESULTS
  YJF exhibited a significant regulatory effect on sperm concentration and motility, the T level and the indexes of the gonad and other accessory glands in the model rats (P < 0.05). After 48 days of treatment, sperm concentrations were (87.85 +/- 28.44), (7.11 +/- 2.15), (35.98 +/- 14.04), (32.65 +/- 11.80) and (33.51 +/- 13.26) x 10(6)/ml in the blank control, infertile model, high-dose YJF, mid-dose YJF, and low-dose YJF groups, respectively; sperm motilities were (52.79 +/- 16.43), (31.14 +/- 3.07), (45.88 +/- 16.97), (51.56 +/- 13.35) and (49.53 +/- 10.16)%; the T levels were (194.07 +/- 40.29), (61.27 +/- 13.70), (121.87 +/- 24.35), (127.44 +/- 19.38) and (127.81 +/- 20.28) nmol/L; the luteinizing hormone (LH) levels were (7.017 +/- 0.269), (6.117 +/- 0.894), (7.060 +/- 0.871), (7.156 +/- 0.937) and (6.967 +/- 0.778) IU/L; the testis volumes were (3.775 +/- 0.183), (2.865 +/- 0.258), (3.236 +/- 0.058), (3.457 +/- 0.066) and (3.398 +/- 0.091) g; the epididymis volumes were (1.119 +/- 0.116), (0.833 +/- 0.226), (1.124 +/- 0.104), (1.132 +/- 0.107) and (1.114 +/- 0.106) g; the prostate volumes were (176.75 +/- 427.09), (131.67 +/- 39.45), (178.70 +/- 37.97), (180.11 +/- 37.39) and (179.00 +/- 35.42) mg; and the body weights were (188.50 +/- 7.12), (189.92 +/- 6.67), (187.42 +/- 5.47), (189.17 +/- 6.19) and (188.75 +/- 6.12) g. Testis histopathology showed obvious injuries in the infertile models and different degrees of improvement in the three YJF groups, most evidently in the mid-dose group.
  
  
  CONCLUSIONS
  Yifing Fang had an evident therapeutic effect on kidney deficiency-related infertility in adenine-induced rat models.
