    A study was undertaken to compare myeloperoxidase (MPO) activity in leukocytes from normal subjects and those with chronic granulomatous disease (CGD) and to eliminate further consideration of MPO as the oxidase responsible for the post-phagocytic respiratory burst and subsequent oxidase microbicidal sequence lacking in leukocytes from patients with CGD. With use of granule fractions isolated from a number of samples, MPO activity in several MPO-mediated biochemical systems (peroxidase assays, protein iodination, and amino acid decarboxylation) was measured. No difference was demonstrated between granule fraction preparations from normal subjects and those with CGD. These data show that MPO activity is normal in CGD leukocytes and are inconsistent with a role for MPO in initiating the post-phagocytic respiratory burst.

    by John Muir.
    Summary: Famed naturalist John Muir (1838-1914) came to Wisconsin as a boy and studied at the University of Wisconsin. He first came to California in 1868 and devoted six years to the study of the Yosemite Valley. After work in Nevada, Utah, and Colorado, he returned to California in 1880 and made the state his home. One of the heroes of America's conservation movement, Muir deserves much of the credit for making the Yosemite Valley a protected national park and for alerting Americans to the need to protect this and other natural wonders. The mountains of California (1894) is his book length tribute to the beauties of the Sierras. He recounts not only his own journeys by foot through the mountains, glaciers, forests, and valleys, but also the geological and natural history of the region, ranging from the history of glaciers, the patterns of tree growth, and the daily life of animals and insects. While Yosemite naturally receives great attention, Muir also expounds on less well known beauty spots.
