Abstract

Objective: The aim of this study was to investigate the negative effects of cigarette on testicular biochemistry and histology of rats and to evaluate if resveratrol could alter these effects. Materials and methods: Thirty-two male Wistar Albino rats were divided into 4 grups for an experiment of 6 weeks. Group 1 was used as control; Group 2 was only exposed to cigarette smoke. Group 3 only received intraperitoneal injections of resveratrol (10 mg/kg/day). Group 4 was exposed to both cigarette smoke and resveratrol (10 mg/kg/day). At the end of the experimental period, the rats were sacrified and testes of all rats were removed. Malondialdehyde (MDA), glutathione (GSH), and nitric oxide (NO) levels were measured on testicular tissue and histopathologic examination was performed with light microscope. Results: Weight follow-up of rats revealed no significant difference among groups. MDA level was lower in cigarette smoke and resveratrol group than that of only cigarette smoke group. GSH level showed significant decrease in only cigarette smoke group, while GSH level increased in cigarette smoke and resveratrol group. Differences in NO levels were not statisticaly significant among groups. The histological evaluation revealed that Johnsen score which indicates spermatogenesis was significantly lower only in cigarette smoke rats than all other groups. Conclusion: Oxidative stress develops in testis of rats that were exposed to cigarette smoke, and resveratrol has preventive effects on this damage with direct or indirect antioxidant activity.

Özet

Amaç: Bu çalışmanın amacı sigaranın sıçan testis biyokimyası ve histolojisi üzerindeki olumsuz etkilerini ortaya koymak ve bu etkinin resveratrol ile değiştirilip değiştirilemeyeceğini incelemektir. Gereç ve yöntem: Bu çalışma için 32 erkek Wistar Albino sıçan 4 gruba ayrılarak 6 hafta süren bir deney yapıldı. Grup 1 kontrol olarak belirlenirken, Grup 2 sadece sigara dumanına maruz bırakıldı. Grup 3’e sadece 10 mgr/kgr/gün intraperitoneal resveratrol uygulandı. Grup 4 ise hem sigara dumanına maruz bırakıldı, hem de eşzamanlı 10 mgr/kgr intraperitoneal resveratrol uygulandı. Deney sonunda hayvanların tümü sakrifiye edilerek testisleri alındı. Testis dokusunda malondialdehid (MDA), glutatyon (GSH) ve nitrik oksid (NO) düzeylerine bakıldı; doku örnekleri ışık mikroskobunda histopatolojik olarak değerlendirildi. Bulgular: Hayvanların tartı takibinde gruplar arasında anlamlı bir fark görülmedi. Sigara ile birlikte resveratrol verilen grupta sadece sigara verilen gruba göre MDA seviyelerinde düşüş gözlendi. Sadece sigara grubunda GSH seviyesinde anlamlı düşüş ve sigara ile birlikte resveratrol verilen gruptaki GSH seviyesindeki artış görüldü. NO seviyeleri gruplar arasında istatistiksel olarak anlamlı farklılık göstermedi. Histolojik incelemede seminifer tübüllerdeki spermatogenezi gösteren Johnsen skoru sadece sigara verilen grupta diğer gruplardan anlamlı olarak düşük bulundu. Sonuç: Sigara dumanına maruz kalan sıçanlarda testiste oksidatif stres ortaya çıkmaktadır ve resveratrol direkt veya dolaylı antioksidan etkisiyle bu hasarı önlemede etkilidir.
