Charts summarizing the behavioral results in rats of control, tibial, and iliac groups. Rats were placed at the center of a 1.5-cm-wide square wooden bridge that was suspended 60 cm above the ground. All animal groups were tested after the injection (one trial/rat) for 3 days per week within 3 weeks and scored from 1 to 4 on beam balance. The scoring was as follows: 1, balances with freezing; 2, balances and walking; 3, hugs the beam or slips without falling; and 4, drops over the beam or hangs on the beam and falls off. The results were calculated as a percentage for each group and by ANOVA to detect significance
