    Abstract:
    Albumin, fibrinogen, alpha 1-acid glycoprotein and cysteine proteinase inhibitor were determined by electroimmunoassay in the media of primary cultures of rat hepatocytes exposed to dialysed supernatants of rat, mouse and human macrophages or to recombinant human and murine interleukin 1 and tumour necrosis factor. Recombinant cytokines in the range of 1 to 1000 ng/ml caused only reduction of albumin synthesis and slight stimulation of alpha 1 acid glycoprotein production while crude preparations of macrophage cytokines elicited typical acute phase response. The results suggest that interleukin 1 or tumour necrosis factor are not likely the principal mediators responsible for the direct stimulation of normal rat hepatocytes to acute phase protein synthesis.
