  • Title: Early changes of lymphocyte RNA and serum immunoglobulins following chronic exposure to benzene.
    Author: Chircu V, Ionescu M, Zgoanţă C.
    Journal: Med Interne; 1981; 19(4):373-8. PubMed ID: 6175016.
    Abstract:
    Hematologic and immunochemical investigations carried out in 270 workers with chronic exposure to benzene demonstrated changes of the nucleologram and of the area of lymphocyte nucleoli as well as disorders of the humoral immune response revealed by radial immunodiffusion. The numerical rise of bi- and polynucleolated cells, of cells with irregular macronucleoli as well as an enlargement of the nucleolar area are assumed to reflect an increase of the endolymphocytic amounts of RNA. An increased capacity of immunoglobulin formation, particularly of IgM, was also observed. All these changes are considered as early signs of an enhanced immune reactivity following chronic exposure to benzene.
