8 rabbits were exposed to metallic nickel dust (2 mg/m3, of which about half was respirable) for 4 weeks. The lungs were lavaged and the macrophages were collected. In comparison with 8 control rabbits, a significant increase was noted in the nickel exposed rabbits as concerned the weight and density of the lungs, the size variation of the lung cells, the phagocytosis of silver coated particles, and the metabolic activity as measured by NBT reduction. The last mentioned increase was recorded during basal conditions as well as during phagocytosis. The NBT reduction during phagocytosis was significantly correlated with the degree of phagocytosis of silver coated particles in both control and exposed rabbits. It is suggested that the exposure to nickel dust has unspecifically activated the macrophages perhaps by increased production of phospholipids.
