Abstract
The fluid and cellular phases of inflammatory resonse have been measured using a technique employing subcutaneous implantation of polyurethane foam cubes impregnated with heat-killed Mycobacterium tuberculosis. Phenylbutazone, azathioprine, aspirin, cyclophosphamide, and prednisolone suppressed fluid response, whereas sodium aurothiomalate, hydroxychloroquine, and D-penicillamine had no effect. All the drugs used suppressed the infiltration of inflammatory cells into the cubes.
