BACKGROUND: Annona muricata is used in traditional African medicine to manage urinary obstruction. In this study, we hypothesized that hexane fraction of Annona muricata (HFAM) seeds will ameliorate testosterone propionate (Tp)-induced benign prostatic hyperplasia (BPh).

METHODS: Castrated rats were assigned into six groups: non-castrated control, castrated control, castrated rats that received Tp (BPh group), [BPh+HFAM], [BPh+HFAM + finasteride], [BPh + finasteride].

RESULTS: The BPh rats had 3.8 and 3.9 folds increases in prostatic and organo-somatic weight, while treatment with HFAM alone and [HFAM + finasteride] decreased prostatic weight by 22% and 34%, respectively. BPh increased the activities of serum and prostatic total acid phosphatase by 95% and 121%; and activities of serum and prostatic alkaline phosphatase by 54% and 281%, respectively. Serum and prostatic lipid peroxidation were increased by 44% and 82%, respectively, in BPh rats with a concomitant decrease in prostatic superoxide dismutase by 73%. In BPh rats, serum and prostatic myeloperoxidase increased by 4.0 and 2.0 folds, while serum nitric oxide increased by 2.4 folds, respectively. Strong expression of induciblenitric oxide synthase, Bcl, beta-catenin, androgen and estrogen receptors were observed in BPh rats. Importantly, treatment with HFAM or finasteride (or combination) attenuated prostatic weight, inflammatory and antioxidant indices in BPh rats.

CONCLUSION: HFAM may serve as novel therapeutic agent against BPh.
