Modulation of delayed-type hypersensitivity reaction (DTH) in mice by synthetic adjuvants and the mode of their action were investigated. Intracutaneous injection of azobenzenearsonate coupled to phosphatidylethanolamine (A-PE) without adjuvant did not induce DTH. Administration of A-PE with the quaternary amines

We assessed the interaction of several pesticides with renal organic anion transport based on inhibition of the active transepithelial transport of p-aminohippuric acid ([3H]PAH) by primary cultures of winter flounder proximal tubules. Four structurally similar chlorophenoxy acid herbicides were tested.
