Isolated rabbit Clara cells and a transformed human bronchial epithelial cell line, BEAS-2B, were used to investigate the mechanism of cytotoxicity of 1,1-dichloro-2,2-bis(p-chlorophenyl)ethane (DDD), a persistent insecticide and stable metabolite of 1,1,1-trichloro-2,2- bis(p-chlorophenyl)ethane. Both BEAS-2B cells and rabbit Clara cells

International journal of immunopharmacology, 8(1), 47-52 (1986-01-01)
The anti-complementary effects of the surface-active immunological adjuvants dimethyldioctadecylammonium bromide (DDA) and pluronic polyols L101 and L121 were investigated in the mouse system. All three adjuvants showed complement (C)-inactivating effects. DDA caused a time- and dose-dependent reduction of alternative pathway

A novel, sensitive system to determine immunological adjuvant activity is presented. It is based on the direct haemagglutinin response of mice to neuraminidase-treated sheep red blood cells (asialo-SRBC) seven days after i.p. immunization. For two model adjuvants it is shown
