Hibernation pattern and ımportance of superoxide dismutase for the Turkish hamster, Mesocricetus brandti (Mammalia: Rodentia)

Mesocricetus brandti’nin hibernasyon özellikleri ve süperoksit dismutaz (SOD)’ın inhibisyon oranı belirlendi. Örneklerin ilk hibernasyona giriş tarihi 2 Kasım ve son örneğin hibernasyondan çıkış tarihi ise 5 Mayıs olarak belirlendi. Bireysel hibernasyon süreleri 8 ile 63 gün arasında değişmektetir ve en uzun kesintisiz hibernasyon süresi 4 gün olarak saptanmıştır. Hibernasyon periyodunda, hayvanlar yüzde 2,7’ den yüzde 38’e kadar değişecek şekilde ortalama 27,1 g ağırlık kaybetmişlerdir. Hibernasyondaki hayvanlarda SOD’un ortalama inhibisyon oranı % 82,3, aktif hayvanlarda ise % 77,5 olarak saptandı. Hibernasyondaki hayvanlardaki SOD’un inhibisyon oranının aktif hayvanlardan % 6,3 oranında yüksek olduğu belirlendi (P < 0,05).

Türk hamsteri'nin Mesocricetus brandti (Mammalia: Rodentia)'' hibernasyon özellikleri ve süperoksit dismutaz'ın önemi

Specimens of Mesocricetus brandti were observed in order to assess the onset of hibernation and the inhibition rate of superoxide dismutase (SOD). The first individual began to hibernate on November 2 and the last animal awoke on May 5. Individual hibernation bouts varied from 8 to 63 days, and the longest uninterrupted hibernation was 4 days. In the hibernation period, the animals lost an average of 27.1 g, ranging from 2.7% to 38% of total body weight. In hibernating animals, the average inhibition rate of SOD was 82.3% while it was 77.5% in active animals. The inhibition rate of SOD in the hibernating animals was 6.3% higher on average than in active animals (P < 0.05).
