Fennel is used as a food plant by the larvae of some Lepidoptera species including in its native range the mouse moth and the Old-World swallowtail. Where it has been introduced in North America it may be used by the anise swallowtail. The word "fennel" developed from the Middle English "fenel" or "fenyl". This came from the Old English "fenol" or "finol", which in turn came from the Latin "feniculum" or "foeniculum", the diminutive of "fenum" or "faenum", meaning "hay". The Latin word for the plant was "ferula", which is now used as the genus name of a related plant. The
Nodular lymphocyte predominant Hodgkin's lymphoma composed of vague nodules of numerous reactive lymphocytes admixed with large popcorn-shaped RSC. Unlike classic RSC, the non-classic popcorn-shaped RS cells of NLPHL are CD15 and CD30 negative while positive for the B cell marker CD20. The anti-CD20 monoclonal antibody Rituximab has been used in lymphocyte predominant Hodgkin's lymphoma with encouraging results. BCL6 gene rearrangements have been frequently observed. The characteristics of NLPHL differ from classical Hodgkin lymphoma (cHL). Lymphocyte predominant (LP) ("popcorn") cells are present embedded in nodules consisting of B cells and other reactive cells (mainly reactive T cells). Reed-Sternberg and Hodgkin (RSH) cells are rarely seen, and
