This study investigated the potential reversal effects of kolaviron extract on busulfan-induced brain and testicular damages and found that kolaviron extract can improve cognitive function and testicular status by inhibiting oxidative stress, down-regulating inflammation and apoptotic mediators.
Previous reports revealed that increased oxidative stress with up-regulated inflammatory proteins and apoptotic factors have serious implications in busulfan-induced chemo-brain and testicular damages. Hence, we investigated the potential reversal effects of kolaviron (KV), a neuro-active extract rich in flavonoids with proven anti-oxido-inflammatory and anti-apoptotic properties, on busulfan-induced oxidative damage, inflammatory proteins, and apoptosis in the brains and testes of male rats. In the treatment-regimen, animals in groups 1 and 2 had saline (10 ml/kg/p.o./day) and dimethyl sulfoxide (DMSO; 10 ml/kg/p.o./day), group 3 received KV extract (200 mg/kg/p.o./day), group 4 was given busulfan (50 mg/kg/p.o./day) and animals in group 5 were pretreated with busulfan (50 mg/kg/p.o./day) successively for 56 days in addition to KV extract (200 mg/kg/p.o./day) from days 29-56. Non-spatial memory function was valuated with a novel-object recognition memory test. Thereafter, testicular and brain oxidative/antioxidant status, proinflammatory- and apoptotic-related proteins, testicular enzymatic markers were evaluated respectively. Kolaviron extract improved cognitive function by increasing exploration of novel-object of busulfan-treated rats. Kolaviron extract reversed busulfan-mediated increased malondialdehyde, 8-hydroxy-2 '-deoxyguanosine, and decreased superoxide dismutase, catalase, glutathione, and glutathione-peroxidase in brains and testes as well as the testicular enzyme markers. Increased brain and testicular weights, and TNF-alpha, IL-1 beta, and NF-kappa beta productions due to busulfan administration were also reduced by the extract. The reduced testicular B-cell lymphoma-2, sperm mitochondrial cytochrome-C, and membrane potential, increased DNA fragmentation, caspases -3 and -9 levels were also profoundly reversed by KV. Additionally, KV extract ameliorated busulfan-induced testicular histopathological changes in rats. Conclusively, KV extract reverses busulfan-induced neuroendopathobiological derangements via oxidative stress inhibition, down-regulation of inflammatory and apoptotic mediators in rats' brains and testes. Practical applications Busulfan is an orally effective chemotherapy drug widely used for cancer treatment. It has been reported that chronic usage of busulfan increases the tendency for carcinogenic and teratogenic activities with severe side effects on the functions of the gonads and other body organs such as brain, popularly regarded as chemo-brain. When taken over a prolonged period of time, busulfan causes sterility in animals and destroyed spermatogonial stem cells along with the seminiferous tubules and sperm morphology of animals as well as memory impairments. The findings from the study revealed that KV extract prevent busulfan-induced cognitive and testicular impairments following kolaviron supplementation. Thus, the findings from this scientific investigation suggest that KV extract could improve the quality of reproductive life and cognitive functions of male patients during busulfan chemotherapy, particularly during prolonged therapy.
