ABSTRACT
Objective:
To study the inhibitory effect of berberine hydrochloride (BBR) on BPH and its underlying mechanism in male rats.METHODS:
Forty male rats were randomly divided into a normal control, a BPH model control, a BBR intervention, and a BBR+Bruceol intervention group, and the BPH model was established in the latter three groups. The animals in the normal and BPH model control groups were treated intragastrically with normal saline, and those in the BBR and BBR+Bruceol intervention groups with BBR at 200 mg/kg and BBR plus Bruceol at 1 mg/kg, respectively, once a day for 14 consecutive days. The prostates of the rats were harvested for measurement of their wet weight and prostatic index, detection of the contents of superoxide dismutase (SOD) and malondialdehyde (MDA) and determination of the protein expressions of nuclear factor E2-related factor 2 (Nrf2), antioxidant response element (ARE) and reduced coenzyme I quinone oxidoreductase (NQO1) in the prostate tissue by Western blot.RESULTS:
The wet weights of the prostate in the normal control, BPH model control, BBR intervention, and BBR+Bruceol intervention groups were (715.63 ± 28.57) mg, (1118.93 ± 36.41) mg, (896.21 ± 20.24) mg and (967.23 ± 24.98) mg, the prostate indexes were 2.10 ± 0.13, 3.45 ± 0.22, 2.75 ± 0.19 and 3.01 ± 0.14, the SOD contents in the prostate tissue were (38.54 ± 5.12) U/mg, (13.98 ± 2.01) U/mg, (26.75 ± 3.19) U/mg and (20.16 ± 4.10) U/mg, and the MDA contents were (3.59 ± 0.83) nmol/mg, (12.63 ± 3.26) nmol/mg, (7.20 ± 1.69) nmol/mg and (9.85 ± 1.71) nmol/mg, respectively. The relative expressions of the Nrf2 protein in the four groups were 0.53 ± 0.06, 0.12 ± 0.03, 0.36 ± 0.04 and 0.25 ± 0.03, those of the ARE protein were 0.69 ± 0.07, 0.21 ± 0.02, 0.50 ± 0.06 and 0.30 ± 0.04, and those of the NQO1 protein were 0.44 ± 0.05, 0.15 ± 0.03, 0.30 ± 0.04 and 0.22 ± 0.03, respectively. There were statistically significant differences in all the above indicators between the normal and BPH model control groups (P < 0.05), as well as between the BPH model control and BBR intervention groups (P < 0.05) and between the BPH model control and the BBR+Bruceol intervention groups (P < 0.05).CONCLUSIONS:
BBR hydrochloride can inhibit prostatic hyperplasia in BPH rats and reduce oxidative stress and pathological changes by activating the Nrf2/ARE pathway.
