Local Shwartzman‐Like Phenomenon Prepared with Haptoglobin‐Hemoglobin Complex and Provoked with Prostaglandin

Abstract
Intradermal injection of haptoglobin‐hemoglobin (Hp‐Hb) complex followed by intravenous injection of prostaglandin (PG) F or E2 produced a local Shwartzman‐like phenomenon (LSLP) in rabbits, whereas PGEj has no provoking action. Intradermal injection of hemoglobin or erythrocytes also produced LSLP when provoked with endotoxin or PGF. The provoking action of endotoxin in the local Shwartzman reaction may not be entirely mediated through PG8.
