Abstract

The aim of this study was to investigate the histological changes in testis of rats exposed to cigareite smoke and effects of caffeic acid phenetyl ester (CAPE) on these changes. For this purpose, 21 male Wistar rats were divided into three groups. Animals in Group l were used as control. Rats in Group II were exposed to cigarette smoke and rats in Group III were exposed to cigarette smoke and injected daily with CAPE. At the end of the 60-days experimental period, all rats were killed by deoapitation. Serum testosterone analysis were performed in the blood samples obtained from ths animals. Following routine histological procedures, testicular tissue specimens were examined under a light microscope. in our study, serum testosterone levels and diameters of seminiferous tubules were found to be decreased in rats exposed to cigarette smoke and these were prevented by the administration of CAPE. Light microscopic examination of testis specimens from rats exposed to cigarette smoke revealed that congestion of vessels and increase of connective tissue in the interstitial space. Additionally, there was vacuolization in the seminiferous tubules anda decrease in spermatogenetic cells. Whereas, exposure of cigarette smoke-induced histological changes were not seen in rats exposed to cigarette smoke and injected with CAPE. in conclusion, it was observed that testicular functions of rats exposed to cigarette smoke were decreased and this decrease was prevented by administration of CAPE.

Özet

Bu çalışmada, sigara dumanına maruz kalan sıçanlara ait testislerde meydana gelen histolojik değişikliklerin incelenmesi ve bu değişiklikler üzerine kafeik asit fenetil ester (CAPE)'in etkisinin araştırılması amaçlandı. Bu amaçla 21 adet Wistar cinsi erkek sıçan üç gruba ayrıldı. Grup l'deki hayvanlar kontrol grubu olarak kullanıldı. Grup II'deki sıçanlar sigara dumanına maruz bırakıldı. Grup IH'deki sıçanlara ise sigara dumanına maruziyet ile birlikte günlük olarak CAPE enjekte edildi. 60 günlük deney süresi sonunda tüm sıçanlar dekapitasyonla öldürüldü. Hayvanlardan alınan kanların serumlarında testosteron analizi yapıldı. Testis doku örnekleri rutin histolojik prosedürlerden geçirilerek ışık mikroskobunda incelendi. Çalışmamızda, sigara dumanına maruz kalan sıçanların serum testosteron seviyeleri ve seminifer tubul çaplarında bir düşüşün olduğu ve bu düşüşün CAPE uygulaması ile engellendiği tespit edildi. Sigara dumanına maruz bırakılan sıçanlara ait testislerin ışık mikroskobik incelenmesinde ise, interstisyel alanlardaki damarlarda konjesyonun olduğu ve bağ dokusunun arttığı gözlendi. Ayrıca, seminifer tubullerde vakuolizasyonun olduğu ve spermatogenik hücrelerin azaldığı görüldü. Sigara maruziyeti ile birlikte CAPE uygulanan sıçanlarda ise, sigara maruziyetinin neden olduğu histolojik değişikliklerin oluşmadığı tespit edildi. Sonuç olarak, sigara dumanına maruz kalan sıçanların testis fonksiyonlarında azalmanın olduğu ve bu azalmanın CAPE uygulaması ile önlendiği görüldü.
