Abstract
Objective: Hyperlipidemia and hypercoagulation are the major risk factors in atherosclerotic events. Low density lipoproteins (LDLs) are the main source of lipids in the athresclerotic plaques within the foam cells. Apoprotein B-100 (Apo-B) is the main protein in the LDL- cholesterol (LDL-C). For this purpose we aimed to investigate blood tissue factor (TF) levels and the TF activity of liver in experimental hyperlipidemia with and without Apo-B conjugate administration.

Methods: Thirty two C57BL/6 mice were divided into 3 groups as control group (n=8), hyperlipidemic group (n=8), hyperlipidemic+Apo-B group (n=8). Mice were sacrified at the end of two months and blood lipid parameters, blood TF levels and TF activity of liver were investigated. Serum lipid parameters were determined by using commercial kits, blood TF levels were determined by Elisa and liver TF activities were measured by Quick method.

Results: Serum levels of total lipid, cholesterol, LDL-C significantly increased in hyperlipidemic group; LDL-C significantly decreased in both Apo-B and LDL conjugate given hyperlipidemic groups. Serum TF increased significantly in short term hyperlipidemia, TF activities in the liver homogenate also increased significantly. There was no effect of Apo-B conjugates on TF values in blood and liver homogenate.

Conclusion: Based on the results of this study Apo-B conjugate administration was effective in hyperlipidemia and hypercoagulation which are important factors in atherosclerosis. On the other hand we believe that new studies are necessary to investigate immunological properties of Apo-B conjugate administration.

Deneysel hiperlipidemi ve Apo-B konjugatı uygulamasının kan doku faktörü seviyesi ve karaciğer doku faktörü aktivitesi üzerine etkileri

Özet
Amaç: Hiperlipidemi ve hiperkoagülasyon ateroskleroz gelişiminde önemli yer tutar. Aterom plakları içinde özellikle yüksek miktarda Apolipoprotein-B 100 (Apo-B) içeren LDL-C (düşük dansiteli lipoprotein kolesterolü) görülmektedir. Bu nedenle deneysel hiperlipidemi oluşturulan sıçanlarda ve Apo-B konjugatı uygulamasının kandaki doku faktörü (DF) miktarı ve karaciğer DF aktivitesi üzerine etkilerini incelemeyi amaçladık.

Yöntem: Bu çalışmada deneysel Apo-B konjugatı ilaveli ve ilavesiz deneysel hiperlipidemi yapılan 32 adet C57BL/6 türü fare her bir grupta 8 fare olacak şekilde 3 gruba ayrıldı (1-Kontrol grubu; 2-Hiperlipidemi grubu; 3-Hiperlipidemi + Apo-B grubu). İki ay sonunda sakrifiye edilen hayvanların rutin lipid parametreleri, kanda ve karaciğer dokusunda doku faktörü (DF) miktarı ve aktivitesi incelendi. Bu amaçla total lipid miktarı, fosfovanilin metodu ile, total ve LDL kolesterol ticari kit kullanılarak, kan DF tayini ELISA yöntemi ile, karaciğer DF aktivitesi ise Quick metodu ile ölçüldü.

Bulgular: Hiperlipidemik grupta total lipid, kolesterol, LDL-C değerleri kontrol grubuna göre anlamlı olarak arttı; LDL-C değeri Apo- B konjugatı ilave edilen grupta azalırken, total lipid ve total kolesterol değerleri arttı. Kandaki DF değerleri anlamlı bir artış gösterdi; Apo-B konjugatı verilen grupta kandaki DF sonuçları değişmedi. Karaciğer homojenatında DF aktivitesi hiperlipidemik grupta hızlandı; Apo- B verilen grupta sonuç değişmedi.

Sonuç: Elde ettiğimiz sonuçlar biyokimyasal yönden değerlendirildiğinde, ateroskleroz patogenezinde önemli olduğu düşünülen hiperlipidemi ve hiperkoagülasyon durumunda Apo-B konjugatı uygulamasının etkili olduğu görülmüştür. Ancak bu konudaki çalışmaların Apo-B konjugatı enjeksiyonunun immunülojik yönlerinin de detaylandırılarak devam etmesinde yarar olduğunu düşünmekteyiz.

Anahtar Kelimeler: Deneysel hiperlipidemi, C57BL/6, Apo-B 100, doku faktörü
