Abstract (2. Language): 
The aim of this study is to find out the effects on physical and mental development at rats that are separated from mothers and put into single housing. This study was conducted in Experimental Animal Research Center of Medical Faculty of Dokuz Eylül University. The ethical approval was taken from Dokuz Eylül University Animal Experiments Ethical Committee. In the study totally 28 rat puppies, 12 male and 16 female born from three Wistar Albino rats were used. 1st group (n: 6) the male rats puppies that have being away from the mother stress. 2nd group (n: 8) the female rats puppies that have being away from the mother stress. 3rd group (n: 6) the male rats puppies who don’t have separation stress. 4th group (n: 8) the female rats puppies who don’t have separation stress. All the puppy rats lived with their mother till the 18th day of their birth. The rats in 1st and 2 nd groups were taken from their mother between 18-30 th days, totally 12 days, 4 hours every day at the same time and same situation. Sucking from the mother was cut at the 30 th day and the puppy rats that are separated from the mothers at the 1 st and 2 nd groups were put to single housing between 30-90 days. On the other hand the other groups who don’t have separation stress were put in cages as males to get his and females to get her. The weight gain, food and water consumption was measured once a week to check out the physical development and water tank test was applied at 30 th and 90 th day to follow the mental development. There was a statistically significant difference (P< 0,05) between the groups that had separation stress and that don’t have this stress when the weight gain and food and water consumption and learning and remembering faculty were compared. At the beginning of the experiment the rats that are separated from the mothers and put in to single housing, who have stress at both races had fright, anxiety, uneasiness, decrease in food and water consumption and all this affected their physical development. But as the time passed, in later weeks the rats that were in stress adapted to the new situation and these rats became more researchers and interfering then the rat groups who don’t have stress. The physical and mental development of the separation stress group was not affected totally negatively as we thought at the beginning of the hypothesis, adversely more positive permanent changes have occurred. When the results of this study is adapted to the effect on the population, by diminishing the protective effect of the parents on children’s development and raising may have positive effect on children’s mental and physical development, but this does not mean that they should be left to the streets.

Abstract (Original Language): 
Bu çalışmada amaç anneden ayrılma stresi ve ardından tek tek ayrı barındırmanın sıçanlarda fiziksel ve mental gelişim üzerine etkilerini araştırmaktır. Bu amaçla anneden ayrılma stresi ve tek tek barındırma stresi yaşayan sıçanlar ile bu stresi yaşamayan sıçanlar olmak üzere iki grup karşılaştırılmıştır. Çalışmada 3 adet hamile Wistar Albino sıçandan doğan 28 adet yavru sıçan kullanılmıştır. Bütün yavrular doğumdan sonra 18. güne kadar anneleri ile birlikte yaşamışlardır. 18.-30. günler arası her annenin yavrularının, yavru sayısı ve cinsiyeti göz önüne alınarak ve randomize olarak seçilmiş yavruların yarısı anneleri ile birlikte yaşamaya devam ederken, diğer yarısı annelerinden ayrılarak günde 4 saat uygun ortamda annelerinden ayrılma stresine maruz bırakılmıştır. 28 sıçan: I. grup (n:6) anneden ayrılma stresi yaşayan ve tek tek ayrı kafeslerde barındırılan erkek sıçanlar, 2. grup (n:8) anneden ayrılma stresi yaşayan ve tek tek ayrı kafeslerde barındırılan dişi sıçanlar, 3. grup (n:6) anne ile birlikte yaşayan ve toplu olarak tek bir kafeste barındırılan erkek sıçanlar ve 4. grup (n:8) anne ile birlikte yaşayan ve toplu olarak tek bir kafeste barındırılan dişi sıçanlar olmak üzere dört gruba ayrılmıştır. Sıçan yavrularında fiziksel gelişimi takip etmek için ağırlık artışları, yem ve su tüketimleri ölçülürken, mental gelişimlerini takip etmek için Water mase su tankı testi yapılmıştır. Deneyin doğumdan itibaren 4. ayda sonlandırılması planlanmıştır. Gruplar arasında ağırlık artışı, yem ve su tüketimleri karşılaştırıldığında Grup 1 ayrılma stresi yaşayan erkeklerin diğer gruplara göre daha fazla yem ve su tüketimi ile ağırlık artışı sağladığı, grupların mental gelişimleri karşılaştırıldığında, ayrılma stresi yaşayanların toplu halde yaşayanlara göre daha araştırmacı, mücadeleci ve mevcut durumu en iyi şekilde değerlendirdiği tespit edilmiştir. Anneden ayrılma stresi ile birlikte tek tek barındırma, sıçanların fiziksel ve mental gelişmelerini etkiler ve davranışlarında kalıcı değişikliklere neden olabilir. Çalışma sonuçları insanlara genellendiğinde, ailelerin çocuklarına yönelik aşırı koruyucu etkilerinin onların fiziksel ve mental gelişimlerini çok da olumlu etkilemediği, ancak bunun çocukların sokaklara bırakılması anlamına da gelmediği söylenebilir.
