This study was conducted to evaluate the pineal glands of the foal and adult horses with histomorphometry. The pineal glands were sectioned at a thickness of 40 µm and stained with AgNOR for stereological analyses. The weight and volume of the pineal gland as well as the number of pinealocytes were significantly higher in the adult horses (P=0.009). However, the number of pinealocytes in per volume was similar between foals and adult horses. Such data indicate that growth in the size of the gland is related to increase in the number of pinealocytes. The pinealocyte nucleus is significantly larger in adults (P= 0.009). Such a size difference should be further investigated if it is due to an increase in the number of cells with increased DNA content. Melanin was distributed throughout the foal pineal gland whereas it was focally localized to connective tissue in adults. The different patterns in melanin distribution suggest that foals and adult horses may differ by means of melanin metabolism in the pineal gland

Bu çalışma, tayların ve yetişkin atların pineal bezlerinin histomorfometrik olarak incelenmesi amacıyla yapılmıştır. 40 μm kalınlığında alınan kesitler, stereolojik analizler için AgNOR ile boyandı. Yetişkin atlarda pineal bezin ağırlığı, hacmi, ve pinealosit sayısı anlamlı derecede yüksek bulundu (P = 0.009). Bununla birlikte, hacim başına düşen pinealosit sayısı tay ve yetişkin atlarla benzerdi. Bu veriler, pinealosit sayısındaki artışa bağlı olarak bezin büyümesine işaret etmektedir. Pinealosit çekirdeği yetişkinlerde belirgin olarak daha büyüktü (P=0.009). Bu durum DNA içeriği artmış hücrelerin sayısının artmasından kaynaklanıyorsa böyle bir boyut farklılığı daha fazla araştırılmalıdır. Melanin, tay pineal bezinin her bölgesine dağılmış bir durumda idi, ancak yetişkinlerde stromanın bağ dokusuna dağılmış vaziyette idi. Melanin dağılımındaki farklılıklar, pineal bezdeki melanin metabolizmasının taylarda ve yetişkin atlarda farklılık gösterebileceğini düşündürmektedir
