A Study of Some Factors in the Chemical Stimulation of the Growth of Aspergillus Niger

“…A glance at experiment 2 (of Nikitinsky) shows that the acidified cultures produce a greater yield (first harvest). Reference, moreover, to experiments 6,7,8,9,and II indicates that in the majority of cases (see, however, Penicillium griseum grown on NH 4NO g, experiments 7 and II) when the acid formed in the first culture has been neutralized, the resulting yield in the second culture does not exceed that in the first. On the other hand, the yields for the second cultures, without neutralization of the acid formed by the first, show as a rule an acceleration of growth.…”

Local Treatment of Tinea Capitis

“…For this purpose they are an essential adjuvant to manual epilation, but iodine or mercury seem as effective as any of the newer fungi¬ cides which were tried. In a report to the Committee on Chemotherapeutics and Other Agents on June 12,1946 Dr. Hinshaw discussed the results of his studies of streptomycin in patients with various forms of. tuberculosis.…”

Radiation hormesis: its historical foundations as a biological hypothesis

“…The establishment of fungal dose-response data near the turn of the century was addressed principally by 3 investigators, including Stevens (105) at the University of Chicago and Clark (22)(23)(24) and Duggar (31 ), who both working out of Cornell University. Clark's research was completed in partial fulfillment of his Master's degree.…”

“…In the case of Clark, 5 fungal species were assessed with 37 compounds over 23 doses per experiment using 3 end points (spore germination, mycelium growth, and the fruiting of spores) (22,23). The author utilized a beet extract for the growth medium, thereby precluding any direct comparison with the results of Stevens (105) and Duggar (31 ), who appear to have used tap water.…”

“…The third paper, that of Duggar (31), had a different goal than that of Stevens (105) and Clark (22)(23)(24), which was, in part, to define the toxicity threshold of harmful substances in molds using the research methodology of Kahlenberg and True (62). Duggar was also interested in a broad range of other questions, including one directly relevant to the present assessment.…”
