  • Title: Respiratory activity and oxidative phosphorylation in mitochondria of the rat brain and liver under conditions of elevated temperature of the environment.
    Author: Skonieczna M, Bicz W.
    Journal: Med Pr; 1984; 35(4):263-7. PubMed ID: 6521637.
    Abstract:
    The rate of oxygen consumption by mitochondrial fractions of the brain and liver of rats under elevated ambient temperature was investigated. The animals were placed in a thermostatized chamber for 6 hours at 21 degrees, 28 degrees or 37 degrees C. During the experiment, relative humidity in the chamber was controlled. After exposure, the animals were decapitated, mitochondrial fractions isolated and oxygen consumption measured with the Clark electrode. Respiratory substrates of succinate and glutaminate with malate were used. The analysis of the obtained results was based on the t-Student test, assuming the values obtained for the animals staying at 21 degrees as the control values. It was found that the 6 hrs stay under the ambient hyperthermy conditions did not induce any disturbances in the respiratory processes and oxidative phosphorylation in rat's brain and liver mitochondria.
