Injected corticosteroids can sometimes lead to a granulomatous reaction. This is apparently also true for anabolic steroids, which are often used by bodybuilders, although we have not found any histologic report on such a phenomenon. We report a case of a granulomatous reaction in a 30-year-old male bodybuilder having undergone anabolic steroid injections. Foreign bodies typical of steroids wer...

A patient presented with granulomatous lung disease associated with the pulmonary deposition of various metallic particles. To evaluate the relation between the metallic dust and the granulomatous process, lymphocyte transformation tests to aluminium sulphate, titanium chloride, beryllium sulphate, and nickel sulphate were performed. A lymphocyte proliferative response to titanium chloride was ...

The expression of chemokines during an immune response may participate in determining the intensity and type of the developing immune response. In the present study, we have examined the effect of overexpressing monocyte chemoattractant protein (MCP)-1 at the site of immunization during different stages of Th1- and Th2-type granulomatous responses. The overexpression of MCP-1 by MCP-1 adenoviru...

Granulomatous inflammation is considered to be an immune mechanism against infections or certain non-neoplastic conditions. Rarely granuloma formation may be noted in neoplastic disorders also. However a granulomatous response in the lymph nodes draining cancers is unusual. Such granulomas may sometimes show tumour cells in their centre. The exact cause of this phenomenon is not known but an im...

Murine schistosomiasis is a granulomatous disease associated with high serum and granuloma angiotensin I-converting enzyme (ACE) activity. SQ 14225, a specific competitive inhibitor of ACE, was administered to normal mice and mice infected with Schistosoma mansoni to determine whether this compound could inhibit granuloma ACE activity and modify the size of the granulomatous response to schisto...

Host granulomatous inflammation in murine schistosomiasis mansoni is a T cell-mediated immune response, which, at the chronic stage of the disease, undergoes T suppressor lymphocyte-dependent modulation. In the present study this phenomenon was further analyzed in vitro. Spleen cells of mice undergoing modulation (20 wk of infection) when mixed with spleen cells of animals exhibiting vigorous g...
