Abstract

Objective: We determined the morphological changes of erythrocytes in blood samples of diabetic patients with varying levels of hyperglycemia with normo- and hyper-cholesterol concentrations and compared them with cells of healthy subjects. Methods: The shape analysis was carried out by shape descriptors based on projected area, perimeter and form factor, as measured by the processing of erythrocyte images. Blood smears were collected from normal subjects and from glycemic subjects with normo- and hyper-cholesterol levels. After image processing techniques like edge enhancement, thresholding, filtering, contour extraction, and pattern analysis and recognition, the images were used for shape analysis. Results: The shape parameters, which quantified the changes in erythrocytes in diabetic subjects with normal cholesterol level, showed significant deviation from the shape of normal cells. Cells of diabetic subjects with hyper-cholesterol level showed more deviation than cells with normal cholesterol. Conclusion: These changes lead to hyper aggregation and to a decrease in deformability of erythrocytes and hence increase microcirculatory complications.

Özet

Amaç: Değişik seviyelerde hiperglisemiye sahip normo- ve hiper-kolesterollü diyabetik hastalardan elde edilmiş kan örneklerinde eritrositlerin morfolojik değişikliklerini belirledik ve sonuçları sağlıklı bireylerin hücreleriyle karşılaştırdık. Metodlar: Şekil analizi, eritrosit görüntülerinin işlenmesiyle ölçülen, ve tahmini alan, çevre ve form faktörünü baz alan şekil belirleyicileri ile yapıldı. Normal bireylerden ve normo- ve hiper-kolesterol seviyelerine sahip glisemik bireylerden kan yaymaları yapıldı. Görüntüler kenar güçlendirme, eşikleme, filtreleme, sınır çıkarma, yapı analizi ve tanıma gibi görüntü işleme tekniklerinden sonra şekil analizinde kullanıldı. Bulgular: Normal kolesterol seviyesine sahip diyabetik bireylerin eritrositlerindeki değişiklikleri belirleyen şekil parametreleri, normal hücrelerin şeklinden anlamlı bir sapma gösterdi. Hiperkolesterol seviyesine sahip diyabetik hastaların hücreleri normal kolesterollü hücrelerden daha fazla sapma gösterdi. Sonuç: Bu değişiklikler, agregasyonun artmasına ve eritrositlerin şekil değiştirebilme özelliğinde bir düşüşe yol açar ve böylece mikro dolaşım ile ilgili komplikasyonlar artar.
