Nitric oxide synthesis was measured as acummulative nitrite levels in culture medium.

  • 3-a After 24 hr of culture, human hepatocytes were not exposed to anything or exposed to 25 U/ml OSM, 100 U/ml IL-6, 100 U/ml LIF, 75 U/ml IL-11, 300 U/ml IFN and 320 U/ml G-CSF, and nitrite levels were evaluated 24 hr later.
