ÖZET

Çalışmada, erişkin kobaylarda ön ve arka bacak uzun kemiklerinin, cinsiyet farklılığı göz önüne alınarak, sağ ve sol kemikler arası homotipik varyasyonu ortaya koymak amacı ile morfometrik değerlerin elde edilmesi, bu değerlerin canlı ağırlık ile olan ilişkisinin incelenmesine kaynak oluşturacak verilerin belirlenmesi amaçlanmıştır. Bu amaçla, 15 dişi- 15 erkek erişkin kobay canlı ağırlıkları, ön ve arka bacaklarına ait uzun kemiklerindeki (humerus, antebrachium, femur, tibia, fibula) osteometrik ölçümler alınmıştır. Sonuç olarak, kobaylarda ön ve arka bacak uzun kemiklerinin sağ ve sol morfometrik değerlerinin birbirine çok yakın ve istatistiki açıdan homotipik varyasyon göstermediği, ancak cinsiyetin önemli bir faktör olduğu ifade edilebilir. Bununla birlikte, cinsiyet faktörünün kobaylar için önemli olmasının osteoarkeolojik çalışmalar açısından yararlılıklar sağlayacağı düşünülmektedir. Laboratuar hayvanı olarak kobaylardan alınan araştırma sonuçlarının diğer türlerde yapılacak olan cinsiyete dayalı çalışmalarda model olarak alınabileceği ve söz konusu kemiklerin simetrik olması nedeni ile kontrol şartları oluşturmak üzere kullanılabileceği söylenebilir.

Anahtar Kelimeler: Kobay, uzun kemik, homotipik varyasyon

 

 

ABSTRACT

 

STUDIES ON HOMOTYPIC VARIATIONS OF FORELIMB AND
HINDLIMB LONG BONES OF GUINEA PIGS

 

The aim of this study was to obtain morphometric data to find out the homotypic variations of right and left long bones of forelimb and hindlimb in mature laboratory animals considering the sex variations, and a data source which will enable to study the correlation between these data and live weight values. For this live weights osteometric values of long bones (humerus, antebrachium, femur, tibia, fibula) of forelimb and hindlimb of 15 male and 15 female laboratory animals are measured. As a result, it can be stated that the right and left morphometric values of forelimb and hindlimb of the laboratory animals are very close and they don't reveal homotypic variations statistically, however it is also concluded that sex variation is an important factor. The results obtained from researches on the guinea pigs as labarotory animals can used as a model for other studies on sex variations of the the different species and it can be stated that, such symmetric bones can be used to form a control environment.

Key Words: Laboratory animal, long bone, homotypic variation
