Abstract

Atherosclerotic patients have impaired endothelial function but the mechanism has not been clarified in detail yet. This study aims to establish blood activity ofarginase in atherosclerotic patients and thus, to make contribution to the efforts of elucidation of possible function ofarginase in the nitric oxide metabolism and endothelial plaque formation process. Arginase activity was measured in erythrocyte and plasma samples from atherosclerotic patients. Activity of the enzyme was found higher in both plasma and erythrocytes from patients compared with healthy subjects. Results suggest that increased arginase activity may play part in reduced synthesis of endothelial nitric oxide and possibly, in the atherosclerotic plaque formation process.

Özet

Özet: Aterosklerotik hastaların endotelyalfonksiyonlarının bozulmuş olduğu bilinmekle birlikte mekanizması henüz aydınlatılmamıştır. Bu çalışmada aterosklerotik hastaların kan arginaz aktiviteleri ölçülerek, arginazm nitrik oksit metabolizması ve endotelyal plak oluşumunda oynadığı muhtemel rol açıklanmaya çalışıldı. Aterosklerotik hastaların eritrosit ve plazma numunelerinde arginaz aktivitesi tayin edildi. Enzim aktivitesi hastaların hem plazma hem de eritrositlerinde sağlıklı kişilere göre yükselmiş bulundu. Sonuçlar, artmış arginaz aktivitesinin, endotelyal nitrik oksit sentezinin azalmasında ve aterosklerotik plak oluşumunda rolü olabileceğim düşündürmektedir.
