    OBJECTIVE: The aim of this study was to investigate the protective effect of short-term usage of fresh pomegranate juice (FPJ) on ototoxicity after cisplatin-based chemo-irradiation. MATERIALS and METHODS: The study was carried out on 56 adult Wistar Albino rats, which were divided into 8 groups (n: 7 for each group). The first group was accepted as the sham control group. However, rats in the seven experimental groups were treated with FPJ; cisplatin; irradiation; irradiation plus FPJ; cisplatin plus FPJ; both cisplatin and irradiation; and combined use of cisplatin, irradiation, and FPJ, respectively. Ototoxicity was evaluated by Distortion Product Otoacoustic Emissions (DPOA), histopathology, and paracochlear protein carbonyl content. RESULTS: The results of the study showed that cisplatin, irradiation, and both cisplatin and irradiation treatments affected hair cells dramatically. However, the results of cisplatin plus FPJ and combined use of cisplatin, irradiation, and FPJ indicated that FPJ plays an important role in protecting hair cells in the inner ear. Additionally, the findings of signal-noise ratio and protein carbonyl values also supported the results stated above. CONCLUSION: Fresh pomegranate juice treatment can be a supportive agent to reduce hair cell injury in the inner ear of patient treated by cisplatin, radiotherapy, or cisplatin-based chemo-irradiation. However, more performance is necessary for further studies, especially on long-term treatment with FPJ.

    Protective effect of Diyarbakir watermelon juice on carbon tetrachloride-induced toxicity in rats
    (Pergamon-Elsevier Science Ltd, 2011) Altas, Sevcan; Kizil, Goksel; Kizil, Murat; Ketani, Aydin; Haris, Parvez I.
    The present study was designed to evaluate the effect of Diyarbakir watermelon (Citrullus lanatus cv. Surme) juice on lipid peroxidation states in rat liver, kidney and brain. In vivo administration of carbon tetrachloride (CCl4) once a week for 28 days caused a significant elevation of serum markers of liver damage, aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin (TB) and decrease in albumin when compared to the control group. However, administration of carbon tetrachloride along with watermelon juice or ursodeoxycolic acid (UDCA) significantly reduces these changes. Increased lipid peroxide (LPO) level was observed in the liver, kidney and brain tissues after CCl4 administration. However, watermelon juice and UDCA treatment prevented the increase in LPO. The results indicated that watermelon juice protects the liver, kidney and brain tissues from experimental CCl4 toxicity in rats and that the protective effect of watermelon juice may be due to its antioxidant activity and inhibition of lipid peroxide formation. In conclusion, present study reveals biological evidence that supports the use of watermelon juice in the treatment of chemical-induced hepatotoxicity. (C) 2011 Elsevier Ltd. All rights reserved.
