The aim of this research was to evaluate the effect of
bedding change frequency on oxidative
stress parameters of rats. In the
experiment; animals were randomly and equally divided into 4 groups, each group
consisted of 6 male rats. Group 1;
bedding change every day, Group 2; bedding change once in 2 days, Group 3;
bedding change once in 4 days, and Group 4; bedding change once in a week. Dust-free wood shavings were used as
bedding material and the study lasted for 2 months. At the end of
experimental period, MDA levels were found to be increased in blood, liver,
kidney, heart, brain, and lung of groups with longer intervals of bedding
change whereas GSH levels of these tissues were decreased. It was also found
that SOD and CAT activities were higher in erythrocyte and lung tissues in Group 1 than the other groups. Moreover, notable histopathological alterations were observed in
the tissues of longer intervals of bedding
change (especially, group 3 and 4). As
a result, it has been determined that long periods of bedding change in animals
causes oxidative stress, tissues damages, and these alterations adversely
affect the life quality of laboratory animals.

Sıçanlarda Altlık Değişim Sıklığının Lipid Peroksidasyon, Antioksidan Durum ve Histopatolojik Değişiklikler Üzerine Etkileri

Öz

Bu araştırmanın
amacı sıçanlarda altlık değişim sıklığının oksidatif stres parametreleri
üzerine etkisi değerlendirmektir. Çalışmada hayvanlar her grupta 6 erkek sıçan
olacak şekilde rastgele ve eşit olarak 4 gruba ayrıldı. Gruplar: Grup 1; her
gün altlığı değişen, Grup 2; 2 günde bir altlığı değişen, Grup 3; 4 günde bir
altlığı değişen ve Grup 4; haftada bir altlığı değişen şeklinde oluşturuldu.
Çalışma 2 ay olacak şekilde planlandı ve altlık malzemesi olarak tozsuz ağaç
talaşı kullanıldı. Çalışmanın sonunda, daha uzun aralıklarla altlık değişimi
olan gruplarda kan, karaciğer, böbrek, kalp, beyin ve akciğer dokularında MDA
düzeylerinin arttığı, bu dokulardaki GSH düzeylerinin ise azaldığı görülmüştür.
Ayrıca, eritrosit ve akciğer dokularında SOD ve CAT aktivitelerinin Grup 1'de, diğer
gruplardan daha yüksek olduğu belirlendi. Ayrıca, daha uzun aralıklarla
altlıkları değişen grupların (özellikle grup 3 ve 4) beyin, akciğer, kalp,
karaciğer ve böbrek dokularında histopatolojik değişiklikler gözlendi. Sonuç
olarak, hayvanlarda uzun aralıklarla altlık değişiminin oksidatif strese, doku
hasarlarına yol açarak laboratuvar hayvanlarının yaşam kalitesini olumsuz
etkilediği belirlenmiştir.
