    Description: The response to different environmental conditions and negative air ions was investigated on cerebral cortical serotonin and cyclic nucleotides. The results indicated that negative air ions alter the weight of the cerebral cortex and that concentrations of serotonin and cyclic nucleotides can be altered both by different environments and by negative air ions. The data stress the importance of the role of the environment when studying the structure and chemistry of the cerebral cortex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Diamond, M C -- Connor, J R Jr -- Orenberg, E K -- Bissell, M -- Yost, M -- Krueger, A -- New York, N.Y. -- Science. 1980 Nov 7;210(4470):652-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6254145" target="_blank"〉PubMed〈/a〉

    Notes: Zusammenfassung Ramanspektra wässeriger Lösungen von H2SO4, (NH4)2SO4, Na2S2O3, Na2S2O6, H2SeO3, KHSeO3 werden beschrieben und einige Schlüsse auf den Bau ihrer Ionen gezogen. Ammoniumsalze geben in Lösung keine für das Ammoniumion charakteristischen Linien. Uranylsulfat gibt eine anscheinend dem UO2-Radikał zugehörende Linie, deren Frequenzenabstand mit dem im Fluoreszenzspektrum übereinstimmt.

    Notes: [Auszug] KELLOGG, YOST AND KRUEGER REPLY- We have several points to make in reply to the comments by Rosenthal and Ben-Hur. First, no one has yet definitely characterized the chemical nature of negative air ions. The work by Shahin1 on the ionic species produced by corona discharge seems quite interesting, ...

    Notes: [Auszug] Figure 1 illustrates the apparatus used in our experiments. To ensure that all negative ions went through the solution to the ground wire, we insulated the ground wire using heat shrink tubing and Teflon tubing to a point well below the solution's surface. A Modulion corona discharge type negative ...

    Notes: [Auszug] This understanding of the vertebrate visual cycle is based upon experiments in which high light intensities were used, and most or all of the rhodospin was bleached. It is not known whether release, reduction and esterification of the chromophore occur after a smaller fraction of rhodopsin is ...

    Notes: Abstract This report describes for the first time the effects of long-term continuous exposures of animals to small air ions and D.C. electric fields. In this study we exposed 200 female NAMRU mice (25/cage) to the following conditions: ± high ions (2×105/cm3), ± low ions (2×103/cm3), ± field only and ground (ion depleted, no field). Specially designed cages provided a defined D.C. field of about 2 kV/meter in ionized environments, with somewhat lower values in the field only cages. Detailed mapping of ion flux originating from a tritium foil generating system (multiple sources in an overhead plate) indicated a well defined, but heterogenous pattern with eight peak areas. Using a 100 cm2 probe, ion flux values ranged from 10−12–10−14 A/cm2, with an average flux of 8.7±6.8×10−13 A/cm2 in high negative ion cages, with good reproducibility between cages. Measurements of serum glucose, cholesterol, and urea nitrogen (samples taken every three months) showed a number of small but consistent and statistically significant differences between animals maintained in different environments during the first year of exposure. Serum globulin and whole blood serotonin, however, did not show any significant environmental effects. Interestingly, pairwise comparisons between high negative and low negative ion conditions, or between high positive and low positive ion conditions, or between the two ground conditions, revealed no significant differences between cages. This argues for a similarity of environmental responses for the mice maintained in each of the compared conditions. The results of a multiple classification analysis for the entire first year showed a preponderence of effects for the ionized cages, although other conditions also had highly significant differences as compared to the grand mean value. While this study has shown effects of only small magnitude (compared to normal physiological variations) in the female NAMRU mice studied here, the significance of these results strongly validates the precept of long-term air ion effects in animals. Given the known variability of different species and strains, future studies will have to determine the actual range of responsiveness of animals exposed on a long-term basis to defined air ion and electromagnetic environments.

    Notes: Abstract This report describes the second year of long-term continuous exposures of female NAMRU mice to small air ions and D.C. electric fields in the following conditions: ± high ions ((2×105/cm3), ± low ions (2×103/cm3), ± field (2 kV/m) only and ground (ion depleted, no field). Using an isolated anesthesized mouse, whole body ion flux values averaged 1.04±0.63×10−10 A in high ion cages for different positions on the cage floor, with about a hundred-fold reduction for low ion cages. During the second year (sample periods 5–8) of exposure serum chemistry variability increased, due to increased pathology and decreased numbers of animals as our experimental population died off. The fifth sample period yielded results consistent with those seen earlier, but later sample periods had many fewer significant differences between cages than did those of the first year. Nevertheless, MCA statistics for serum glucose for the second year found a pattern remarkably similar to the first, with the low ion cages (LN and LP) having the lowest levels. MCA statistics for both years emphasized this possible “window” effect of low level ionized conditions. Also, a comparison between the combined values for ionized (HN, LN, HP and LP) and ion depleted cages (NF, PF, G1 and G2) showed a highly significant difference (p〈10−6) for serum glucose for both years of exposure, with lower glucose values seen for animals in the ionized cages overall. Animals of all conditions also showed a highly significant decrease in serum glucose with age. Comparison of mice in ionized cages vs. the non-ionized cages also resulted in a significant difference (p〈.013) for survival characteristics between groups, with ion exposed animals having a shorter lifespan. These statistics argue strongly for significant effects of long-term exposure of NAMRU mice to the ionized environment.
