[Evaluation of the preserved state of dog lungs by means of oxidative and phosphorylative functions in mitochondria].

The preservative state of dog lungs was estimated by means of parameters of the oxidative and phosphorylative function in mitochondria. The function of the mitochondria was tested polarographically before and 24 respectively 48 hours after preserving. After 24 hours the function of the mitochondria was not essentially changed. After 48 hours there were observed considerable changes. The change became visible in a decrease of the volume of the respiratory activity of the mitochondria. It was a characteristic reaction of small energetic mitochondria. The results prove the preservation of viability of the lung tissue after a 24-hours' preservation respectively the restriction of the viability after 48 hours.
