Rapamycin treatment improves morphology of spinal neurons in rats with spinal cord injury.

(A) Morphology of spinal neurons in rats (Nissl staining). Arrows indicate Nissl bodies. Scale bars: left, 500 μm; right, 100 μm. (B) Quantity of Nissl bodies in spinal neurons. Data are expressed as the mean ± SD (n = 4). Comparisons between groups were performed using the unpaired Student's t-test, and discrepancies among multiple groups were tested using one-way analysis of variance. **P < 0.01, vs. sham group; ##P < 0.01, vs. saline group.
