Cohnheim Cohn·heim (kōn'hīm'), Julius Friedrich. 1839-1884.
German pathologist noted for his microscopic investigations into inflammation and pus formation and for his development of the technique of freezing a tissue sample before cutting it into thin slices for microscopic examination.
cohnheim has demonstrated the existence of the wandering corpuscles in cases of inflammation.
The fact that this immense army of phagocytes is always in motion was first clearly recognized by cohnheim, in 1867.
The theory that tumours originate from fœtal residues or “rests,” is associated with the name of cohnheim.
cohnheim and Weil describe a similar condition in the tongue of frogs after ligature of the lingual artery.
cohnheim lays stress upon this fact in connection with his theory of the origin of tumors.
