Intense acid phosphatase and mild alkaline phosphatase activity was seen in lining epithelium of bursa. The follicle associated epithelium showed positive PAS and alcia! blue reaction. Medullary cysts of bursa and intracellular cysts of thymus also stained positive. Lipids were seen from 14th week onwards in thymus.
