Abstract

Amaç: Bu çalışmada, karbon tetraklorür ve tiyoasetamid (CCl4 ve TAA) modellerinde alanin aminotransferaz (ALT), aspartat aminotransferaz (AST), albümin, trigliserit ve kolesterol gibi biyokimyasal parametreler ve histopatolojik özellikler değerlendirilerek doz ve zamana bağlı olarak daha etkin modelin ortaya çıkarılması amaçlanmıştır.

Yöntem: Her bir model için ratlar 3 gruba ayrılmıştır ve intraperitoneal (i.p.) olarak CCl4 (0.5 ml/kg, 1.0 ml/kg, 2.0 ml/kg) ve TAA (100 mg/kg, 200 mg/kg, 300 mg/kg) 4, 6 ve 8 hafta boyunca hafta da üç kez enjeksiyon yapılmıştır.

Bulgular: Biyokimyasal araştırmalar sonucunda ALT ve AST değerleri, sadece 0,5 ml CCL4 6. ve 8. hafta gruplarında kontrol gruplarına göre istatistiksel olarak anlamlı fark göstermiştir (p<0.05). Diğer biyokimyasal parametrelerin değerleri kalan gruplar arasında anlamlı farklılık göstermemiştir (p>0.05). Histopatolojik sonuçlara
bakıldığında karaciğer dokusunda, kontrol gruplarının her ikisinde de karaciğer, normal histolojik yapısını göstermiştir. Diğer bütün gruplarda, artan zaman ve doza bağlı olarak her iki modelde göze çarpan hepatofibrotik değişiklikler gözlemlenmiştir.

Sonuç: Doz ve zamana bağlı olarak sekizinci haftaya ulaşan gruplarda siroz geliştiği gözlemlenmiştir. Bu sonuçlar hepatofibrotik çalışmalar için yarayışlı birer referans olabilecektir.

Determination of effects of chemical agencies on liver fibrosis models frequently used in different dose and time periots

Abstract

Aim: In this study, it was aimed to reveal a more effective model depending on the dose and time by evaluating histopathological properties and biochemical parameters, such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin, triglyceride, cholesterol in carbon tetrachloride and thioacetamide (CCl4 and
TAA) models.

Method: Rats were divided into three groups for each model and intraperitoneally (i.p.) injected with CCl4 (0.5 ml/kg, 1.0 ml/kg, 2.0 ml/kg) and TAA (100 mg/kg, 200 mg/ kg, 300 mg/kg) for 4, 6 and 8 weeks, three times weekly, respectively.

Results: In the biochemical investigation, ALT and AST values in the only 0,5 ml CCL4 of groups for 6 and 8 weeks and were found to have significant differences compared to the control groups (p <0.05), while the other biochemicals parameters values did not reveal significant difference in the groups (p >0.05). According to the
results of the histopathology in the liver tissues, both the control groups showed a normal histological feature. The hepatofibrotic alterations were remarkable in the CCl4 and TAA models fibrosis depending on the increasing dose and time in all of the groups.

Conclusion: Our results showed that the dose and time were reached up to until the cirrhosis for eighth week. These results would be a helpful reference for hepatofibrotic studies.
