Figure 5.11. Reactive oxidant production by human neutrophils. In (a), neutrophils (5 x lOVml) were suspended in buffer containing 10 pM luminol in the presence and absence of a mixture of the extracellular oxidants scavengers SOD (1 /ig/ml), catalase (2 pg/ml) and methionine (0.25 mg/ml, to scavenge HOC1). In (b), neutrophils (1 x 106/ml) were suspended in buffer containing 75 jUM cytochrome c (to measure Of production) or 4 jUM scopoletin plus 5 /ig/ml horseradish peroxidase (to measure H202 production). In (c), neutrophils (2 x lOfyml) were placed in the chamber of a Clark-type 02 electrode. All measurements were made at 37 °C cell suspensions were stimulated by the addition of 1 /

Manganese is an important element in the aquatic environment. It is an essential micronutrient U 2) and is the subject of much interest because its oxides scavenge other heavy metals (3). Of particular interest are ferromanganese nodules, which are abundant in the aquatic environment. These nodules contain high concentrations of cobalt, nickel, copper and other heavy metals (4).

After the water was collected in the reaction vessel, 288 ppm ferrous sulfate was added. Addition of a stoichiometric quantity (100 ppm) of potassium permanganate thus resulted in formation of hydrous ferric and manganese oxides. Scavenging eflBciencies for this precipitation reaction have been reported previously (5, 6). The resulting suspension was agitated for 10-20 min and allowed to settle for 12-24 hr, after which the supernatant hquid was siphoned. The precipitate was removed and...

The fact that this reaction proceeds rapidly and quantitatively at room temperature demonstrates the tremendous affinity that phosgene has for the oxide ion, even when bound to such a powerful oxide scavenger as niobium(V). Analogous results have been found for the tantalum system, in both room-temperature [120a] and high-temperature ionic liquids [1977c].

Studies by Thomas and Stocker180 and Christen et al.181 indicated that the formation and release of the aminophenolic antioxidant 3-hydroxyanthra-nilic acid (3-HAA) via the kynurenine pathway are responsible for the ability of interferon-y-primed human macrophages to inhibit the oxidation of low-density lipoprotein (LDL), an event implicated as an important event in atherogenesis. 3-HAA efficiently inhibits LDL oxidation by acting as an aqueous oxidant scavenger and a synergist for LDL-associated vitamin E.
