[The hematic histamina in malignant tumors of alimentary canal and respiratory apparatus (author's transl)].

The Authors estimated the blood histamine level in 39 subjects with malignant tumors of the lung (19), Sthomac (11) and colon (9) and found a significant increase with respect to normal values. Among the groups investigated, the subjects with gastric tumors presented the greatest values. The results show a significant relationship between tumor and hyperhistaminemia as demonstrated by other Authors in experimental animals.
