Immunitätsf., Bd. 89, 1937)150719373379319310207202102072021Copyright © 1937, Editorial B.1937<p>The author studied the trypanocidal effect of some dyes (trypanrot, tryparosan, trypaflavin), arsenic derivatives (arsenophenylglycine atoxil, salvarsan), emetic derivatives (antimosan, fuadin emetic) and naganol on different strains of Tr. brucei. The results he obtained show that the medicinal effect of trypanocidal substances is not constant, and their therapeutic dose varies greatly depending on the properties of the trypanosis strain in which they are used. These data, which fully coincide with the instructions of Schilling, Duke, Kline, and others, indicate that the results obtained in the study of the medicinal effect of the drug on old strains are only of relative value in the practice of tropical countries.</p>Kazan Medical archiveКазанский медицинский архив
