  • Title: [Acetylcholinesterase activity in brain slices of rats subjected to cooling].
    Author: Emirbekov EZ, Klichkhanov NK.
    Journal: Ukr Biokhim Zh (1978); 1986; 58(6):63-6. PubMed ID: 3798582.
    Abstract:
    The acetylcholinesterase (AChE) activity is studied in rat slices of the cerebral cortex, corpus striatum, hypothalamus and medulla oblongata of rats during hypothermia (20 degrees C) and also 1 and 7 days after the posthypothermal period. Cooling of animals down to 20 degrees C is accompanied by an increase in the AChE activity in the brain both under incubation temperature of 20 degrees and 37 degrees C. Under prolonged hypothermia the AChE activity in the investigated brain regions, except for corpus striatum, returns to the control level. By the 7th day of posthypothermal period the AChE activity in corpus striatum, hypothalamus and medulla oblongata does not restore completely. The most substantial changes in the AChE activity both under hypothermia and posthypothermal period occur in corpus striatum, which obviously reflects its complicated functional role.
