Appearance of hybridoma growth factor/interleukin-6 in the serum of mice bearing a methylcholanthrene-induced sarcoma.
Serum concentrations of hybridoma growth factor/interleukin-6 progressively increased in mice bearing a transplantable methylcholanthrene-induced sarcoma with tumor growth. Elevated HGF/interleukin-6 concentrations were also positively correlated with increased serum concentrations of the hepatic acute phase reactant protein, amyloid P. Daily Indomethacin treatment of sarcoma-bearing mice prolonged survival and reduced the magnitude of the serum amyloid P response, but failed to attenuate either tumor growth or serum HGF/interleukin-6 responses. Since previous studies have demonstrated that neither interleukin-1 nor tumor necrosis factor-alpha can be detected in the serum of these sarcoma-bearing mice, and that HGF/interleukin-6 is a principal mediator of the hepatic acute phase response, we conclude that circulating HGF/interleukin-6 may contribute significantly to the host responses which accompany experimentally-introduced cancer. Furthermore, prostanoid inhibition does not appear to regulate the synthesis and release of HGF/interleukin-6 during tumor growth.

Immunological aspects of pyelonephritis.
Several virulence factors, such as O and K antigens and capacity to attach to uroepithelial cells, seem to be required for Escheria coli to cause acute pyelonephritis. These factors induce an immune response, however, which can modify the course and clinical expression of the infection. During acute pyelonephritis, autoantibodies to the Tamm-Horsfall protein increase. These antibodies, which probably are evoked by a cross-reaction noted between structures of E. coli LPS and the Tamm-Horsfall protein, may add to the renal tissue engagement in interstitial nephritis caused by bacterial pyelonephritis.
