Added enzymatic antioxidants, superoxide dismutase or catalase, scavenging superoxide anions and H2O2, suppressed this enhanced proliferation.
Added scavengers (alpha-tocopherol acetate, scavenging lipid peroxidation, or sodium azide, histidine, mannitol, scavenging singlet oxygen, superoxide anions, and hydroxyl radicals, respectively), or N-acetyl cysteine, the thiol-reducing agent, suppressed the response, but to different extents.

The lipid peroxide formation was inhibited by dithiothreitol (DTT) (free radical scavenger), NaN3 (singlet oxygen and free radical scavenger), and superoxide dismutase (SOD) (superoxide scavenger) but was enhanced by the presence of deuterium oxide (D2O) (enhancement of singlet oxygen lifetime).
Formation of these photodecomposition products was inhibited in the presence of sodium azide (NaN3), a free radical inhibitor.

Potassium cyanide, a Cu,Zn-superoxide dismutase inhibitor, abolishes the toxic effect of Abeta (25-35) to erythrocytes, whereas mercaptosuccinate, a glutathione peroxidase inhibitor, and ouabain, a Na+,K+-ATPase inhibitor, promote it.

RESULTS: Ragweed pollen grains contain NAD (P) H oxidase activity, which is diphenyleneiodonium-sensitive and quinacrine-sensitive and sodium azide-resistant.
These NAD (P) H oxidases generate a superoxide anion that can be converted to H2O2 by pollen grain-associated superoxide dismutase.

Copper sulphate enhanced relaxation to Angeli's salt and SNAP but this resulted from reduced destruction of nitric oxide by superoxide rather than from enhanced generation of nitric oxide, since it was mimicked by superoxide dismutase and by the superoxide dismutase mimetic, MnCl2.

ROS-scavenging enzymes such as catalase and superoxide dismutase, and the lipophilic antioxidative agents, alpha-tocopherol and beta-carotene, showed preventive effects on NP-induced ROS generation.
An NADPH-dependent oxidase inhibitor, diphenyl iodonium chloride (DPI), and a myeloperoxidase inhibitor, sodium azide (NaN3), showed remarkable inhibitory effects on ROS generation induced by NP, but an inhibitor against mitochondrial respiratory function, potassium cyanide (KCN), did not exhibit a significant effect.

Singlet oxygen (1O2) did not seem to play an important role in the UVA-induced DNA-damage since the specific 1O2 scavenger sodium azide (NaN3) and the less specific 1O2 scavenger beta-carotene did not markedly prevent either DNA-damage or H2O2 production.

During photoirradiation in the presence of 5,5-dimethyl N-oxide pyrroline (DMPO), a specific probe for superoxide, ESR signals for DMPO-OOH were formed, and these signals were quenched by superoxide dismutase.
The involvement of singlet oxygen on the induction of lipid peroxidation was also evidenced by the observation that lipid peroxidation was inhibited by sodium azide and enhanced by deuterium oxide.

METHODS: The association of 111In-labeled model protein drugs, bovine serum albumin (BSA), superoxide dismutase (SOD), soybean trypsin inhibitor (STI), and [Asu1.7]-eel calcitonin (Asu-ECT), with the monolayers of LLC-PK1 renal epithelial cells was characterized under various conditions.
The association of STI decreased with increases in medium pH from 5.4 to 8.4 and was inhibited significantly by 2,4-dinitrophenol, sodium azide, cytochalasin B, and colchicine, suggesting that the cellular association involved endocytosis.

When the reactions are conducted in the presence of superoxide dismutase, the total hydrogen peroxide produced is decreased, more so in the presence of the peptides (up to 50%), suggesting the intermediacy of superoxide in these reactions.
On the other hand, the presence of sodium azide or sodium formate, traps for hydroxyl radicals, has no appreciable effect on the total hydrogen peroxide production for the Cu-Hst systems.
