Özet

Objective: Coenzyme Q10 (CoQ10) administration is known to increase CoQ10 concentrations in the mitochondria of brain cells and facilitate the memory and learning processes in rats. This study aims to evaluate the effects of CoQ10 treatment on learning and memory functions in rat pups during early stages of development. Methods: A total of 21-day-old 24 pups were divided into 3 groups (8 pups in each group). A low dose of CoQ10 was administered via oral gavage once per day to one group, a high dose was administered to another group, and olive oil was administered to the control group. The cognitive and learning functions of rats in these groups were evaluated by the Morris water maze and probe tests. Results: Coenzyme Q10 administration was continued for 10 days. At the end of the 37th day, the water maze test was used to evaluate learning and memory performance. No difference was observed in the test results among the high-dose, low-dose and control groups during the 5 days of training in the water maze test (p>0.05). Data from the probe trial indicated no statistically significant differences among rats that received high-, or low-dose CoQ10 or olive oil (control) (p=0.853). Conclusion: In our study, it was determined that administration of high-, or low-dose CoQ10 during childhood does not have a significant effect on learning and memory functions.

Abstract

Amaç: Koenzim Q10 (CoQ10) uygulamasının, beyin hücrelerinin mitokondrisinde CoQ10 konsantrasyonlarını arttırdığı ve sıçanlarda bellek ve öğrenme süreçlerini kolaylaştırdığı bilinmektedir. Bu çalışma, erken çocukluk dönemindeki yavru ratlarda CoQ10 tedavisinin öğrenme ve bellek üzerine etkilerini değerlendirmeyi amaçlamaktadır. Yöntem: Toplam 24 adet 21 günlük yavru 3 gruba ayrılmıştır (her grupta 8 yavru). Bir gruba günde bir kez ağızdan gavaj yoluyla düşük dozda CoQ10 uygulanmışken diğer gruba yüksek dozda uygulanmıştır, kontrol grubuna ise zeytinyağı uygulanmıştır. Ratların öğrenme ve hafıza işlevleri, Morris su labirenti ve prob test ile değerlendirilmiştir. Bulgular: Koenzim Q10 uygulamasına 10 gün süreyle devam edilmiştir. Otuz yedinci günün sonunda, öğrenme ve bellek performansını değerlendirmek için su labirenti testi kullanılmıştır. Su labirenti testinde 5 günlük eğitim boyunca yüksek doz, düşük doz ve kontrol grupları arasındaki test sonuçlarında herhangi bir fark gözlenmemiştir (p>0,05). Prob deneyinden elde edilen veriler, yüksek doz CoQ10, düşük doz CoQ10 veya zeytinyağı (kontrol) alan ratlar arasında istatistiksel olarak anlamlı farklar olmadığını göstermiştir (p=0,853) Sonuç: Çalışmamızda, çocukluk döneminde yüksek doz ve düşük doz CoQ10 uygulamasının öğrenme ve bellek fonksiyonları üzerinde anlamlı bir etkisi olmadığı saptanmıştır.
