Thyroxine and triiodothyronine levels in premature calves

Çalışmada prematür buzağılarda serum total $T_4$ and total $T_3$ konsantrasyonlarım tespit etmek amaçlandı. Bu çalışmada, 20 adet prematür ve 10 adet yeni doğmuş sağlıklı buzağı materyal olarak kullanıldı. Prematür buzağılarda serum $T_4$ düzeyi yeni doğmuş sağlıklı buzağılara göre yüksek (10.4±0.6 $\mu$ g/dl) (p

Prematür buzağılarda troksin ve triiodotronin düzeyleri

The aim of this study was to determine serum total $T_4$ and total $T_3$ concentrations in premature calves. For this purpose, 20 premature calves and 10 healthy newborn calves were used as material. Premature calves had higher serum T4 levels (10.4+0.6 $\mu$ g/dl) (p<0.001) and lower serum $T_3$levels (1.2±0.02 ng/ml) ((p<0.001) than did newborn calves. Serum triglyceride, cholesterol and glucose concentrations were lower (p<0.001) in premature calves than in newborn calves. The importance of thyroid hormones in premature calves requires further studies.
