Sprague Dawley Ratlarda Kısa Fotoperyotun Bazı Kan Parametrelerine Etkisi: I-Enzim Seviyeleri
Outbred Sprague dawley ratlarda, kısaltılmış ışık süresinin vücut ağırlık artışı ve bazı kan enzim seviyelerine etkisi incelendi. Yavrular (n=96), 12 sa. aydınlık/karanlık (kontrol) ve kısaltılmış ışık (9 sa. aydınlık/15 sa. karanlık: muamele) olmak üzere iki fotoperiyot şartına maruz bırakıldılar. Muamele grubu ratlarda, 15 haftalık yaşta, bazı enzim parametreleri, kontrol grubu ile karşılaştırıldı. Kontrol ve muamele grupları arasında ağırlık artışı ve CK-MB (myokardial kreatin kinaz) enzimi hariç diğer enzim seviyelerinde farklılık gözlenmedi (P > 0.05). Sprague dawley ratların, kısa fotoperiyot şartlarında, rutin uygulanan fotoperyot şartarındaki gibi, ağırlık artışı ve kan enzim seviyeleri değişmeden yetiştirilme şansı olabildiği sonucuna varıldı.

The effect of short photoperiod on body weight gain and some enzyme levels in outbred Sprague dawley rats was examined. The pups (n= 96) were assigned into two photoperiod groups: 12 h of light/dark (control) and short photoperiod (9 h light/15 h dark: experiment). The enzyme levels in the experimental group rats were compared to those of control group, at 15 weeks of age. No significant differences (P>0.05) were observed between control and experimental groups, with regard to body weight gain and measured enzymes, except for CK-‐MB (myocardial creatine kinase). It is concluded that, outbred Sprague dawley rats could be kept under short photoperiod conditions, without marked change in the levels of weight gain and some blood enzymes. Key words: Enzyme, Photoperiod, Sprague dawley.
