Abstract
Liver cirrhosis is a diffuse state with replacement of the normal lobular architecture by abnormal nodules and fibrous septa. The Laennec staging system subdivides cirrhosis into 3 groups (4A,4B,4C) based on the thickness of fibrous septa and the size of nodules. 
This study aimed to assess the degree of liver cirrhosis through ultrasonographical and histopathological study after the administration of CCl4, in order to establish a canine model of liver cirrhosis for further research work. Experimental induction of liver cirrhosis was carried on 18 skeletally mature mongrel dogs using carbon tetrachloride (CCl4) for 16 weeks; dogs were evaluated for cirrhosis using ultrasonographical examination with portal vein (PV) and hepatic vein (HV) diameter, histopathological changes every 4 weeks and finally postmortem examination. Liver fibrosis was subdivided through liver biopsy under the guidance of ultrasonography using the Laennec staging system. Liver cirrhosis was confirmed by abnormal liver ultrasononography with portal hypertension, liver cirrhosis on biopsy sample was scored 4A,4B,4C based on the thickness of the fibrous septa and the size of nodules according to Laennec staging system. The degree of liver cirrhosis was recorded through ultasonographical and histopathological examination.
