Publication: Ratlarda Egzersize Bağlı Probiyotik Kullanımının Oksidatif Stres Üzerindeki Etkisi
Abstract
Bu çalışmanın amacı, probiyotik ve egzersizin oksidatif stresin bir belirteci olan tiyol disülfit dengesi üzerindeki etkisini araştırmaktır.Erkek albino Wistar sıçanlar (n = 28) rastgele olarak dört gruba ayrıldı: kontrol (K), egzersiz (E), probiyotik (P) ve probiyotik + egzersiz grubu (PE). L. rhamnosus, L. paracasei L. acidophilus ve B. lactis içeren bir probiyotik kapsül günaşırı olarak (5 x 109 CFU bakteri konsantrasyonu) verildi. Probiyotikler 1 ml steril su içerisinde çözüldü. Egzersiz uygulaması, 8 hafta boyunca haftada 5 gün yapıldı. Probiyotik uygulaması 8 hafta boyunca günaşırı olarak uygulandı. Deney protokolünün tamamlanmasının ardından oksidatif stres parametrelerinin belirlenmesi için serum total tiyol ve doğal tiyol konsantrasyonları ölçüldü. Dinamik disülfit düzeyi (DD), azaltılmış tiyol (RT), okside tiyol (OT) ve tiyol oksidasyon azaltma (TOR) yüzde oranları karşılaştırıldı. Gruplar arasındaki fark SPSS v.21 Anova testi ile analiz edildi ve alfa değeri p <0.05 olarak kabul edildi.K grubuyla karşılaştırıldığında, serum DD düzeyleri PE grubunda anlamlı derecede düşük ve E grubunda en yüksek olduğu tespit edildi. En düşük OT ve en yüksek RT oranları PE grubunda olduğu tespit edildi. En yüksek OT değeri E grubunda gözlendi. PE'de TOR değerleri en yüksek düzeyde bulundu.Sonuç olarak, egzersizin oksidatif stresi artırdığı ve egzersizle birlikte probiyotik uygulamasının dinamik disülfit değerini düşürdüğü ve oksidatif hasarı önemli ölçüde azalttığı tespit edilmiştir. Ayrıca, bu çalışmada kullanılan oksidatif stres ölçüm yöntemi, sporcuların performansını değerlendirmek ve geliştirmek için pratik ve kullanışlı bir yöntemdir.

The aim of this study was to investigate the effect of probiotic and exercise on thiol disulfide balance, which is a marker of oxidative stress. Male albino Wistar rats (n = 28) were randomly divided into four groups as follows: control (K), exercise group (E), probiotic group (P), and probiotic + exercise group (PE). A pool of probiotics that L. rhamnosus, L. paracasei L. acidophilus ve B. lactis was given for 8 weeks every other day (5×109 CFU of bacteria). Prior of gavage, the probiotics were diluted in 1 ml of sterile water. Exercise administration was performed 5 days per week for 8 weeks. Following completion of the experimental protocol, to determine oxidative stress parameters, serum total thiol and native thiol concentrations were measured. Dynamic disulfide status (DD), reduced thiol (RT), oxidized thiol (OT), and thiol oxidation reduction (TOR) percentage ratios were compared between the groups. The difference between the groups was analyzed by SPSS v.21 Anova test and the alpha value was assumed to be p<0.05.In comparison with the control group, serum DD levels were significantly lower in the PRBex group and highest in the EX group. The lowest OT and the highest RT rates were determined to be in the PRBex group. The highest OT value was observed in the EX group. TOR values were found to be highest in the PRBex.As aresult, it has been found that exercise increases oxidative stress and probiotic application together with exercise decreases dynamic disulfide value and significantly reduces oxidative stress measurement method used in this study is a promising practical and useful method to evaluate and improve the performance of athletes.
