C60 fullerene effect on the dynamics of fatigue processes in rat soleus muscle after ischemia-reperfusion
Effect of pristine C60 fullerene aqueous colloid solution (C60FAS; 1 mg/kg dose) on the dynamics of fatigue processes in rat soleus muscle after ischemia-reperfusion injury using the tensiometric method was studied. Experiments were conducted during the first 5 h and for 5 days after ischemia. The changes in maximal strength of muscle contraction and its level of generation between the beginning and end of stimulated irritation after intravenous and intramuscular administration of C60FAS unmodified fullerene aqueous colloid solution were analyzed. The pronounced protective effect of this drug on the dynamics of skeletal muscle contraction was first determined. Protective effect of C60FAS unmodified fullerene aqueous colloid solution relative to changes in the levels of muscle contraction strength generation between the beginning and end of stimulated irritation was 15% in the first 5 h after ischemia and increased to 92% on the 5th day of the experiment. In such a case, the intravenous therapeutic administration of C60 fullerene aqueous colloid solution was the most optimal: the protective effect was 67% versus 49% under intramuscular administration. Thus, the development of biomedical nanotechnology with the application of pristine C60 unmodified fullerene as a strong antioxidant opens up new possibilities in prevention and treatment of ischemic injury in the skeletal muscles.
