Human polymorphonuclear cell (PMN) viability, morphology, adherence, chemotaxis, oxidative metabolism, degranulation and phagocytosis were evaluated following treatment with sanguinarine (SANG). SANG was noncytotoxic to PMNs at all concentrations tested (0.31-200 microM). SANG entered the PMNs rapidly without altering the membrane fluidity and localized in the nuclear matrix. SANG (1.56-6.21 microM) inhibited chemotaxis, chemokinesis and adhesion in a dose-dependent manner, with a complete inhibition at 6.2 microM concentration. Concentrations of SANG up to 1.56 microM did not affect PMN oxidative burst; however, higher concentrations were found to inhibit basal as well as PMA-induced superoxide anion generation. The effect of SANG was time- and dose-dependent, and could be reversed if the PMNs were exposed to 12.5 microM or lower concentrations of SANG for less than 5 min. Autologous serum increased the tolerance of PMNs to SANG. Exogenous Ca2+ or Mg2+ did not alter the SANG-mediated inhibition of PMN functions. Treatment of PMNs with 3.12 microM or higher concentrations of SANG also resulted in inhibition of PMN degranulation and phagocytosis. The results suggest that SANG-mediated inhibition of PMN functions, without cytolysis or resultant release of inflammatory mediators, may have clinical implications.
