Evaluation of nucleolar organizer region in normal brain tissues and Astrocytic Gliomas.
Biomedica Jan ;22(1):41-7.

This study was performed to evaluate the importance of Ag NORs in different grades of Astrocytic Gliomas. It was a descriptive study and was performed at Lahore General Hospital and Sheikh Zayad Hospital, Lahore. A total of 50 cases were collected within one year, and AgNOR staining was performed on 50 brain tumors and specimens were selected randomly. AgNOR was low, high, higher and highest in Astrocytic Gliomas, grade I (Pilocytic), II, III, and IV respectively as compared to normal brain tissue. AgNOR staining technique is a .simple, quick and a cheap method to assess proliferative index in astrocytic Proliferative activity is a good parameter to assess the disease outcome in astrocytic glioma.
