Hepatocellular Carcinoma in Sheep

Hepatocellular carcinoma in a sheep

At necropsy of a five-year-old sheep, a pear shaped, lobular yellow-brownish mass measuring about 12 ×15 × 20 cm was found to involve the right hepatic lobe. Microscopic examination revealed two trabecularand solid patterns of neoplastic hepatocytes. In solid pattern, there were numerous tumoral giant cells thatcontain one or more large hyperchromatic bizarre-shaped nuclei scattered among clust...

Prognostic molecular markers in hepatocellular carcinoma (Review article

Hepatocellular carcinoma (HCC) is the 5th commonest malignancy worldwide and is the third most common cause of cancer-related death. The prevalence is different in the world. The ability to predict patients at higher risk of recurrence and with a poor prognosis would help to guide surgical and chemotherapeutic treatment according to individual risk. As understanding of hepatocarcinogenesi...

Preclinical studies of 166Ho-chitosan for treatment of hepatocellular carcinoma

Introduction: Recently, due to the special characteristics of 166Ho and chitosan, 166Ho-chitosan complex was developed for treatment of tumors such as hepatocellular carcinoma. This complex has been lately prepared with high radiochemical purity in our lab. The preclinical studies of the complex however should be performed to evaluate the tracer concentration in target and...

DNA methylation of tumor suppressor genes in hepatocellular carcinoma

The basic unit of chromatin is a nucleosome included an octamer of the four core histones and 147 base pairs of DNA. Posttranslational histones modifications affect chromatin structure resulting in gene expression changes. CpG islands hypermethylation within the gene promoter regions and the deacetylation of histone proteins are the most common epigenetic modifications. The aberrant patterns of...

DISCRIMINATION OF HEPATOCELLULAR CARCINOMA FROM CIRRHOTIC NODULES BY AgNOR STAIN

Discrimination of regenerative cirrhotic nodules of the liver (CN) from hepatocellular carcinoma (HCC) is sometimes difficult. We examined the utility of AgNOR staining in this context. Fifteen cases of HCC and 25 cases of CN were stained by AgNOR method and the mean AgNOR number for one hundred nuclei in each case was determined. There was a significant difference between the mean AgNOR c...
