argyrophil

 [ahr-ji´ro-fil]
easily impregnated with silver; said of cells or tissues that bind with silver salts, which can then be reduced to produce a brown or black stain.

The pathogenesis is still unclear; however, PDD may be caused by various pathologic changes, such as an increase in the number of Lewy bodies in brain tissue, neurofibrillary tangles, senile plaque formation, microvascular lesions, and the presence of argyrophilic inclusion bodies [4-8].

Different researchers have carried out different methods to assess the grading of the different types of ameloblastomas of which one of the methods which assess the proliferative activity of ameloblastoma are argyrophilic nucleolar organizer regin (AgNOR) which stains the proteins with silver stain which is associated with active nucleolar organizer regions (NOR|), these are DNA loops that transcribe to ribosomal RNA directs protein synthesis and ribosomal formation.9 AgNOR numbers rise with the proliferative activity of the cell, AgNOR are used to diagnose histopathological aspects of various benign and malignant lesions.10
