Synchronized cells of the Harding Passey melanoma grown in culture were given a heat shock treatment of 44 degrees C for 36 min. Thymidine incorporation was measured at frequent intervals after heat shock to determine the time of onset of the next DN

Spermine interacted with serum polyamine oxidase (PAO) to arrest proliferation of cultured Bri8 lymphocytes. Arrest was independent of catalase activity and was not directly due to an H(2)O(2) byproduct. Arrest was averted by 3-hydroxybenzyloxyamine,

Serum polyamine oxidase (EC 1.4.3.4) is known to react in vitro with radio-labelled spermine4+ to produce di-oxidized spermine which must incorporate the label. Di-oxidized spermine was compatible with a radio-labelled compound2+ separated from the r

Hog kidney diamine oxidase (DAO) interacted with 1,3-diaminopropane, putrescine and cadaverine to arrest proliferation of cultured mammalian cells. The byproducts of DAO-substrate interaction, H2O2 and NH4+ are themselves cytotoxic but were apparentl

SUMMARY: Paper chromatograms of hydrolysates of 118 micro-organisms were examined in a study of the distribution of α, e-diaminopimelic acid and other amino-acids. A method for the identification of α, e-diaminopimelic acid is described. Diaminopim

SUMMARY: Diaminopimelic acid decarboxylase was found to be widely distributed among 58 coli-aerogenes organisms. Different strains grown and tested under standard conditions showed great variations in enzyme activity although the amount of diaminopim

Radiation protection by glycerine was examined using the smaIl red- pignnented bacterium Serratia marcescens. Observations indicated that the protection of aerobic organisms was brought about by some mechanism other than oxygen scavenging or competit

An improved procedure ts described for studying the effect of oxygen and nitric oxide on the radiosensitivity of human cells in tissue culture. Data are included on the survival of human cells after 200 kv x radiation during equilibration with oxygen
