77,552 | Oxidation of biologic molecules by ozone: The effect of pH | O'Neill, CA; van Der Vliet, A; Hu, ML; Kaur, H; Cross, CE; Louie, S; Halliwell, B | 1,993 | Ozone (O3) is a powerfully oxidizing pollutant gas. Its toxic effects to animals appear to be worsened by coexposures to acid-generating compounds such as oxides of nitrogen and sulfur. Ozone (16 ppm) oxidizes ascorbic acid and uric acid (two important antioxidants in lung lining fluids) at equal rates at pH 5.0 or pH ... | 0 |
44,191 | Asthma related to occupational and ambient air pollutants in nonsmokers | Greer, JR; Abbey, DE; Burchette, RJ | 1,993 | We attempted to determine the association between occupational and air pollutant exposure with the development of adult asthma through the analysis of a standardized respiratory questionnaire administered to a cohort of 3914 nonsmoking adults in 1977 and again in 1987. Ambient air pollution concentrations were estimate... | 1 |

50,501 | Health effects of urban air pollutants Guideline values and conditions in Sweden | Victorin, K | 1,993 | The level of sulphur dioxide in cities has declined in many countries, and in Sweden it hardly constitutes a health problem any more. The level of nitrogen dioxide, on the contrary, has not declined, The guideline value for nitrogen dioxide is exceeded in areas with high traffic density, and may be close to the level w... | 0 |

43,932 | Caveats regarding the use of the laboratory rat as a model for acute toxicological studies: modulation of the toxic response via physiological and behavioral mechanisms | Watkinson, WP; Gordon, CJ | 1,993 | The rodent, specifically the laboratory rat, is the primary experimental animal used in toxicology testing. Despite its popularity, recent studies from our laboratory and others raise a number of questions concerning the rat's appropriateness as an animal model for toxicological studies. While there may be additional a... | 0 |
53,076 | Effects of ozone and climate on ponderosa pine (Pinus ponderosa) growth in the Colorado Rocky Mountains | Peterson, DL; Arbaugh, MJ; Robinson, LJ | 1,993 | #Long-term radial growth trends of ponderosa pine (Pinus ponderosa var. scopulorum) were studied in second-growth stands in the Front Range of the Colorado Rocky Mountains to determine if there has been any impact from oxidant air pollufion. Although ozone concentrations are relatively high at some locations, visible p... | 0 |
52,844 | Regulation of the expression of rbcS and other photosynthetic genes by carbohydrates: a mechanism for the "sink regulation" of photosynthesis? | Krapp, A; Hofmann, B; Schafer, C; Stitt, M | 1,993 | These experiments were carried out to investigate whether accumulation of carbohydrate leads to decreased expression of genes involved in photosynthesis. Addition of glucose to autotraphic cell suspension cultures of Chenopodium led to a large and reversible decrease of the steady state transcript levels of rbcS, cab a... | 0 |
78,090 | Atmospheric formation and fates of toxic ambient air pollutants | Pitts, JN, Jr | 1,993 | Concentrations of de novo toxicants in ambient air are typically in the ppb range, compared to ppm for occupational exposures. Despite this, some species such as ozone, alone or in combination with other pollutants, have significant health impacts, especially on populations such as children, the elderly, and asthmatics... | 0 |
21,582 | Simulation of the degradation of limestones and dolomitic sandstone under dry deposition conditions | Haneef, SJ; Johnson, JB; Thompson, GE; Wood, GC | 1,993 | Commission of the European Communities. A laboratory-based exposure rig has been employed to quantify the effects of the dry deposition of individual pollutants (SO2, NO2 and NO), with or without ozone (O3), on the degradation of limestones and dolomitic sandstone. In addition to employing dry stones, wetting of the st... | 0 |
86,326 | Variation in antioxidant enzyme activities in anatomic subcompartments within rat and rhesus monkey lung | Duan, X; Buckpitt, AR; Plopper, CG | 1,993 | Antioxidant enzymes including catalase, superoxide dismutase, glutathione peroxidase, and glutathione S-transferases are thought to be the primary cellular defense against reactive oxygen species. Since pulmonary injury produced by oxidant air pollutants like ozone is highly focal, involving primarily the trachea and c... | 1 |
44,203 | Mast cells modulate acute ozone-induced inflammation of the murine lung | Kleeberger, SR; Seiden, JE; Levitt, RC; Zhang, LY | 1,993 | We hypothesized that mast cells modulate lung inflammation that develops after acute ozone (O3) exposure. Two tests were done: (1) genetically mast-cell-deficient (WBB6F1-W/Wv, WCB6F1-SI/SId) and bone-marrow-transplanted W/Wv mice were exposed to O3 or filtered air, and the inflammatory responses were compared with tho... | 1 |

The acute effects of the inhalation of O3 at ambient or near-ambient concentrations on bronchoalveolar lavage (BAL) end points consistent with a distal lung inflammatory response have been well documented in human subjects. Animal toxicologic studies have shown ... | 1 |
