Publication: Sağlıklı Anadolu Manda Sütlerinde Siyalik Asit Düzeyinin Belirlenmesi
Abstract
Amaç: Büyüme ve gelişme faktörleri ile koruyucu molekülleri içeren süt, memelilerin doğum sonrası gelişiminde, organizmanın ihtiyacı olan enerji ve besin öğeleri arasında önemli bir yer tutmaktadır. Manda sütü, zengin biyolojik aktif moleküller içeriğine sahip olması nedeniyle gerek insanoğlunun gerekse de manda yavrularının beslenmesinde önemli bir yere sahiptir. Siyalik asit, gerek insanlarda gerekse hayvanlarda hücrelerin normal fizyolojik işlevine katkıda bulunan amino şeker ailesidir. Sunulan tez çalışmasının amacı, laktasyon periyodunda bulunan sağlıklı Anadolu mandalarının sütlerinde siyalik asit düzeyinin belirlenmesidir. Materyal ve Metot: Sunulan tez çalışmasında, Samsun ilinde halk elinde bulunan laktasyon periyodundaki 100 adet, 3-6 yaşlı mandadan alınan süt örnekleri kullanıldı. Mandaların dört ayrı meme lobundan alınan süt örneklerinde Kaliforniya mastitis test (CMT) ve sütte somatik hücre sayımı (SHS) gerçekleştirildi. CMT negatif ve SHS <200.000 olan sağlıklı süt örnekleri tezin süt materyalini oluşturdu. Süt örneklerinde siyalik asit düzeyi enzim bağlı immünosorbent analiz (ELISA) yöntemi ile ölçüldü. Bulgular: Laktasyon periyodunda bulunan Anadolu mandalarından elde edilen sağlıklı süt örneklerinde siyalik asit düzeyinin en düşük 298 mg/L ve en yüksek 567 mg/L olduğu saptandı. Anadolu manda sütündeki ortalama siyalik asit düzeyi, 72,6 mg/L standart sapma ile 398,1 mg/L olarak belirlendi. Sonuç: Bu tez çalışmasının, siyalik asitin ekzojen kaynağı olarak bilinen sütteki düzeyine yönelik yapılacak araştırmalara katkı sağlayacağı öngörülmektedir.
Aim: Milk, which contains growth and development factors and protective molecules, has an important place among the energy and nutrients needed by the organism in the postnatal development of mammals. Because of its rich content of biologically active molecules, buffalo milk has an important place in the nutrition of both human beings and buffalo offspring. Sialic acid is a family of amino sugars that contribute to the normal physiological function of cells in both humans and animals. The aim of the presented thesis is to determine the level of sialic acid in the milk of healthy Anatolian buffaloes in the lactation period. Material and Method: In the presented thesis study, milk samples taken from 100 buffaloes, 3-6 years old, in the lactation period, were used. California mastitis test (CMT) and milk somatic cell count (SHS) were performed on milk samples taken from four different mammary lobes of buffaloes. Healthy milk samples with negative CMT and SHS <200.000 formed the milk material of the thesis. Sialic acid levels in milk samples were measured by enzyme-linked immunosorbent analysis (ELISA) method. Results: The lowest level of sialic acid as 298 mg/L and highest level as 567 mg/L in healthy milk samples obtained from Anatolian buffaloes in the lactation period was found. The mean sialic acid in Anatolian buffaloes milk was determined as 398.1 mg/L, with a standard deviation of 72.6 mg/L. Conclusion: It is envisaged that this thesis study will contribute to the researches on the level of sialic acid in milk, which is known as an exogenous source.
