    Abstract:
    Effects of some metabolic inhibitors, as well as of biologically active compounds (diakarb, ethidium bromide and a phenanthridine alkaloid sanguinarine) on the formed novocaine and neutral red segregation zones were studied. The volume of granules diminished under the influence of a glycolytic inhibitor iodoacetate, uncouplers of oxidative phosphorylation (2,4-dinitrophenol and carbonyl cyanide trifluoromethoxyphenylhydrozone), and respiratory inhibitors (antimycin A and rotenone), as well as under the influence of cycloheximide - an inhibitor of protein synthesis. Diakarb, ethidium bromide or sanguinarine also provoked a regression of the segregation zones. It has been found that all these compounds are inhibitors of ATPase activity of the isolated segregation zones. A possible mechanism of volume decreasing in segregation zones under the influence of both the metabolic inhibitors and diakarb, ethidium bromide and sanguinarine is discussed.
