  • Title: Energy metabolism and lysosomal events in hemorrhagic shock after aprotinin treatment.
    Author: Horpácsy G, Schnells G.
    Journal: Circ Shock; 1980; 7(1):49-58. PubMed ID: 6156027.
    Abstract:
    Changes in activity of lysosomal enzymes and levels of adenine nucleotides were investigated during hemorrhagic hypotension and following recovery in rat kidneys. The effect of aprotinin pretreatment on these parameters was also tested, and the results were compared to saline-treated controls. Hemorrhagic hypotension led to a release of lysosomal enzymes and to extreme depletion of ATP. The pretreatment with aprotinin inhibits the changes in enzyme activities, but it has no effect on ATP loss during the hypotension. After reinfusion of the shed blood, however, the pretreated animals showed a faster rate of ATP regeneration. The results suggest an interaction between lysosomal enzyme release and ability of mitochondria to resynthetize high-energy compounds during the recovery period.
