The neuroprotective activity of nerve growth factor adsorbed on poly(butyl) cyanoacrylate nanoparticles was evaluated in rats with intracerebral posttraumatic hematoma - hemorrhagic stroke (HS) induced by brain tissue destruction in the internal capsular area. When re-administered intraperitoneally for 3 days, nerve growth factor (5 μ) adsorbed on poly(butyl) cyanoacrylate nanoparticles coated with polysorbate-80 attenuated HS-induced neurological deficit and coordination disorders, optimized rat orientative-exploratory behavior and motor activity, improved reproduction of a conditioned passive avoidance response, prevented the death of the animals, and diminished their weight loss. The findings suggest the potential neuroprotective effect of nerve growth factor (5 μ) adsorbed on polysorbate-80-coated poly(butyl) cyanoacrylate nanoparticles.
