Serological Cross-Reactivity to Rat Anti H-Y Antiserum in the Female European Eel (Anguilla anguilla)

Anti H-Y antiserum, raised in highly inbred Lewis rats, was absorbed with gonadal cells from European eels of both sexes. It was found that rat anti H-Y antiserum cross-reacts with gonadal cells from the eel ovary but not with eel testicular cells. From these results it is suggested that in the European eel, the female is the heterogametic sex.     

Fine needle aspiration in nodular fasciitis of the face

Nodular fasciitis (NF) appears typically as a rapidly growing solitary mass which is most commonly located on the extremities, followed by the trunk and then the head and neck. NF is often suitable for fine needle aspiration (FNA), but few reports of NF diagnosed cytologically have been published. The purpose of this paper is to describe FNA cytology in three cases of nodular fasciitis. All three cases were located on the face.
