  • Title: [The specific characteristics of the vertebrate electroretinogram evoked by x-rays].
    Author: Savchenko BN.
    Journal: Fiziol Zh SSSR Im I M Sechenova; 1991 Aug; 77(8):99-106. PubMed ID: 1668593.
    Abstract:
    Summarised electroretinograms (ERGs) of dark-adaptable retina of Rana temporaria were studied in situ with an automated experimental device with programmable control and first and second derivatives electron differentiation. X-rays were shown to induce the ERG composed of two components which were conventionally designated as the first and second roentgen responses (R-1 and R-2). These differ by their parameters from the ERGs induced by red and blue light in the same experiment. Administration of sodium azide, sodium nitrite, monoiodine acetate and other compounds changed the waves of R-1 and R-2 as well as photo-induced ERGs. This suggests their relative independence and different mechanism of initiation, and allows their partial isolation for separate studying.
