| 1 | The in-vivo assessment of Turkish propolis and its nano form on testicular damage induced by cisplatin显示文摘Objective: Chemotherapeutic drugs, such as cisplatin(CP), which are associated with oxidative stress and apoptosis, may adversely affect the reproductive system. This study tests whether administration of propolis and nano-propolis(NP) can alleviate oxidative stress and apoptosis in rats with testicular damage induced by CP.Methods: In this study, polymeric nanoparticles including propolis were synthesized with a green sonication method and characterized using Fourier transform-infrared spectroscopy, Brunauer-EmmettTeller, and wet scanning transmission electron microscopy techniques. In total, 56 rats were divided into the following seven groups: control, CP, propolis, NP-10, CP + propolis, CP + NP-10, and CP + NP-30.Propolis(100 mg/kg), NP-10(10 mg/kg), and NP-30(30 mg/kg) treatments were administered by gavage daily for 21 d, and CP(3 mg/kg) was administered intraperitoneally in a single dose. After the experiment,oxidative stress parameters, namely, malondialdehyde(MDA), glutathione(GSH), glutathione peroxidase(GPx), and catalase(CAT), and apoptotic pathways including B cell leukemia/lymphoma-2 protein(Bcl-2)and Bcl-2-associated X protein(Bax) were measured in testicular tissues. Furthermore, sperm quality and weights of the testis, epididymis, right cauda epididymis, seminal vesicles and prostate were evaluated.Results: Propolis and NP(especially NP-30) were able to preserve oxidative balance(decreased MDA levels and increased GSH, CAT, and GPx activities) and activate apoptotic pathways(decreased Bax and increased Bcl-2) in the testes of CP-treated rats. Sperm motility in the control, CP, and CP + NP-30 groups were 60%, 48.75%, and 78%, respectively(P<0.001). Especially, NP-30 application completely corrected the deterioration in sperm features induced by CP.Conclusion: The results show that propolis and NP treatments mitigated the side effects of CP on spermatogenic activity, antioxidant situation, and apoptosis in rats. | Pinar Tatli Seven Ismail Seven Selcan Karakus Seda Iflazoglu Mutlu Seyma Ozer Kaya Gozde Arkali Merve Ilgar Ezgi Tan Yesim Muge Sahin Deniz Ismik Ayben Kilislioglu | 2021 | Journal of Integrative Medicine2021，19，5： | 0 |
