This study investigated the role of chrysin (CR) in DNA damage likely to occur in the
testicle and oxidative stress caused by doxorubicin (DXR). Twenty-eight rats were divided into four groups as control, DXR, DXR + CR and CR groups. Sperm parameters,
oxidative status, testicular biopsy score, DNA damage and plasma testosterone levels
were analysed. Noticeable reductions in sperm count, motility and testosterone were
detected in the DXR group compared to controls. In addition, significant increases in
malondialdehyde (MDA), catalase (CAT) and glutathione (GSH) levels, and in abnormal sperm rates were detected. Severe degenerative changes occurred in the tubules
of DXR rat testes; the inter-tubular areas were oedematous. Immunofluorescence
staining was conducted with 8-OhDG (8 oxo-2′-deoxyguanosine) to evaluate DNA
damage, and severe positivity was found in tubular gaps in the DXR rat testes. When
the DXR + CR group was compared with the DXR group, the abnormal sperm rate
was found to have decreased significantly. Positivity in the tubular space and degenerative changes in the seminiferous tubules were also diminished. We recommend
the administration of CR with DXR to reduce the possible adverse effects of DXR, a
medicine preferred in cancer therapy.
