Diagnostic Significance of Agnor Counting in Bovine Tumors

The present research was carried out to know the significance of AgNOR counting in diagnosis of bovine tumors. For this study tumor suspected tissue samples were collected from postmortems, college and city veterinary hospital, veterinary dispensaries in and around Tirupati and subjected for AgNOR staining and counting of AgNOR dots in different tumor cells. The AgNORs appeared as round to irregular, dark brown to black dots of varying sizes in the nuclei. The mean AgNOR count of the individual bovine tumors varied from 3.1 to 5.97. Highest and lowest mean AgNOR counts were observed in myxosarcoma and fibroma with the values of 5.97 and 3.1, respectively. The malignant tumors had numerous and smaller AgNORs when compared to benign or less malignant tumors.
