ABSTRACT
BACKGROUND: To determine the effect of kolaviron on some biochemical parameters in benign prostatic hyperplasia (BPH) rats. METHODS: BPH was induced in rats using a mixture of dihydrotestosterone and estradiol valerate (10:1). RESULTS: The lethal dose of kolaviron was 3050mg/kg body weight. Body weights, relative heart weight (RHW), relative liver weight (RLW), serum levels of prostate specific antigen, prolactin, estradiol, testosterone, testosterone/estradiol ratio, aspartate transaminase (AST), alanine transaminase (ALT), urea, creatinine and prostatic levels of total proteins in the normal rats administered finasteride (standard drug) or kolaviron were not different (P>0.05) from normal control whereas most of these parameters were altered in the disease control except RHW, RLW, AST and ALT. Finasteride (5mg/70kg) or kolaviron (100 and 200mg/kg) ameliorated most of these parameters compared with disease control except RHW, RLW, prolactin, AST, ALT, urea and creatinine (for kolaviron at 100mg/kg). The normal rats administered finasteride or kolaviron had decreased prostate weights (P<0.05) compared with the normal control which results were corroborated by histological assay that also showed that treatment with kolaviron (200mg/kg) or finasteride reversed the histoarchitecture of the prostates of the BPH rats. CONCLUSION: Kolaviron could be useful in the management of BPH.
