title: [Changes in the sorption properties of LDH protein in the rat brain after the single administration of a formaldehyde solution].
abstract: The study of the activity, protein charge and isoenzyme LDG spectrum after a single injection of formaldehyde solution has demonstrated a rise in the protein negative charge, which in the absence of ischemia was observed for 20 min. A more than 5-min increase in LDG protein charge observed in ischemia and independent of changes in LDG isoenzyme spectrum was significantly less expressed in ischemic brain after a preliminary injection of formaldehyde solution. With cerebral blood flow preserved, an injection of formaldehyde resulted in the alteration of LDG spectrum, namely a rise in LDG3+4+5 content. Formaldehyde injection prior to ischemia prevented the development of a similar effect, which was significantly more expressed in ischemic brain without a preliminary formaldehyde injection.
