Macrophages and tissue injury: agents of defense or destruction?
The past several years have seen the accumulation of evidence demonstrating that tissue injury induced by diverse toxicants is due not only to their direct effects on target tissues but also… Expand

UVB Light Stimulates Production of Reactive Oxygen Species
In keratinocytes, UVB light stimulates the production of reactive oxygen species (ROS). Lysates of these cells were found to possess a non-dialyzable, trypsin- and heat-sensitive material capable of… Expand

Free Radical Biology and Medicine
Nitric oxide and various by-products including nitrite contribute to tissue injury by forming novel intermediates via redox-mediated nitration reactions. Nitration of unsaturated fatty acids… Expand

Inhibition of skin tumorigenesis by rosemary and its constituents carnosol and ursolic acid.
A methanol extract of the leaves of the plant Rosmarinus officinalis L. (rosemary) was evaluated for its effects on tumor initiation and promotion in mouse skin. Application of rosemary to mouse skin… Expand

Functional heterogeneity in liver and lung macrophages
Although initially considered merely “scavenger cells” that participate in immunologic responses only after B and T lymphocytes have performed their biological tasks, more recent evidence suggests… Expand

Percutaneous absorption of trihalomethanes, haloacetic acids, and haloketones.
Bathing in chlorinated drinking water causes significant exposure to potentially toxic disinfection by-products (DBPs). In the present studies, we measured the permeation coefficients (K(p)) of three… Expand

Mechanisms mediating the vesicant actions of sulfur mustard after cutaneous exposure.
Sulfur mustard (SM), a chemical weapon first employed during World War I, targets the skin, eyes, and lung. It remains a significant military and civilian threat. The characteristic response of human… Expand

Inhibitory effects of curcumin on in vitro lipoxygenase and cyclooxygenase activities in mouse epidermis.
Topical application of curcumin, the yellow pigment in turmeric and curry, strongly inhibited 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced ornithine decarboxylase activity, DNA synthesis, and… Expand

Reduced hepatotoxicity of acetaminophen in mice lacking inducible nitric oxide synthase: potential role of tumor necrosis factor-alpha and interleukin-10.
Macrophage-derived inflammatory mediators have been implicated in tissue injury induced by a number of hepatotoxicants. In the present studies, we used transgenic mice with a targeted disruption of… Expand

Application of the Amplex red/horseradish peroxidase assay to measure hydrogen peroxide generation by recombinant microsomal enzymes.
The formation of reactive oxygen species by the cytochrome P450 monooxygenase system is thought to be due to autoxidation of NADPH-cytochrome P450 reductase and the nonproductive decay of… Expand
