Reduced Renshaw Recurrent Inhibition after Neonatal Sciatic Nerve Crush in Rats
Figure 6
Spinal motoneuron and peripheral muscle change 7 weeks after the 5-day-old sciatic nerve crush. (a) Photograph taken under low magnification (4x) showing nerve crush side of the spinal cord with the HRP labeled cells is located on dorsolateral part of the anterior horn. The hole pointed by the arrow indicates the HRP injected side. (b) Examples of cross-sections from reinnervated (B) and contralateral control (A) gastrocnemius muscles from a 5-day-old sciatic nerve crush rat stained for SDH 7 weeks after nerve crush. (c-d) Bar diagrams showing the motoneuron number of the gastrocnemius pool (c) and gastrocnemius and soleus muscle weights (d) in 5-day-old sciatic nerve crush rats 7 weeks after reinnervation. The scale bar in ((a)(A) and (a)(B)) is 500 μm and in ((b)(A) and (b)(B)) is 80 μm. *** in comparison with the sham control.
