Abstract

The aim of this study was to investigate the effects of the iodide application on the body weight, TSH, FT3, FT4, follicular diameter, amount of colloid and epithelial height from one to six week-old chickens that were provided iodide in drinking water until six weeks of age beginning at hatching. A sum of 100 broiler chickens was used in the study. Iodide with 98-99% purity was added to the drinking water of animals in the experimental group for the first six weeks of age at a concentration of 2 mg/L. Ten chickens from both the control and the experimental groups were weighted at days 1, 2, 3, 4 and 6 of the experiment. Blood samples were collected to determine the concentrations of the serum TSH, FT3 and FT4. Thereafter, animals were decapitated and thyroid glands were taken. Paraffin blocks were prepared and three serial sections of 5 |am thickness were taken with 50 interval. Serial sections were stained with a triple staining method for a general histological evaluation and with the Periodic Acid Shiff (PAS) reaction to demonstrate the presence of colloid. Results indicated that the iodide supplementation altered the production order of the TSH, FT4 and FT3. When the thyroid follicles were investigated, follicle diameters and the area covered by the colloid increased with age in both groups. Epithelial height of the thyroid gland remained to be higher for a longer period of time in the experimental group. It was also observed that follicle diameters increased at the first and second weeks of age and the area covered with colloid within the follicles increased at the first, third and fourth weeks of age. The increase in FT4 and FT3 levels as a consequence of iodine application occurred earlier in the experimental group than the control group. Mean folllicular diameter and the amount of colloid were also higher in the experimental group.

Özet

Bu çalışmada, kuluçkadan çıktıktan sonra altı hafta boyunca sularına iyot ilave edilen civcivlerde; iyodun bir haftalıktan altı haftalık yaşa kadar, canlı ağırlık, TSH, FT3, FT4, tiroid folikül çapı, kolloid miktarı ve folikül epitel yüksekliğine etkilerinin araştırılması amaçlandı. Çalışmada, 100 adet broyler civciv kullanıldı. Deneme grubunun, içme suyuna % 98-99 saflıkta 2 mg/lt oranında iyot katkısı yapıldı. Civcivler 1, 2, 3, 4 ve 6 haftalık olduklarında deneme ve kontrol gruplarından 10'ar adet hayvanın ağırlıkları ölçüldü ve TSH, FT3 ve FT4 seviyelerinin belirlenmesi amacıyla kan örnekleri alındı. Daha sonra dekapite edilerek tiroid bezleri çıkarıldı. Hazırlanan parafın bloklardan 50 ^ım ara ile 5 |im kalınlığında üç seri kesit alındı. Kesitlere genel histolojik inceleme için üçlü boyama yöntemi, kolloid demonstrasyonu için Periyodic Acid Shiff reaksiyonu (PAS) uygulandı. İyot ilavesinin TSH, FT4 ve FT3'ün oluşma düzenini etkilediği görüldü. Tiroid folikül hücreleri incelendiğinde, iki grupta da folikül çapı ve kolloidin kapladığı alanın yaşa bağlı olarak arttığı belirlendi. İyot alan grupta tiroid epitelinin daha fazla süre yüksek kaldığı; folikül çapının 1 ve 2. haftalarda, kolloidin folikül içerisinde kapladığı alanın 1., 3. ve 4. haftalarda arttığı saptandı. Sonuç olarak; iyot kullanımı FT4, FT3 hormonlarının kontrol grubuna göre daha önce artmasına, folikül çapının ve kolloid miktarının da daha yüksek olmasına sebep olmuştur.
