Fig. 6From: Effect of herbal extracts on peripheral nerve regeneration after microsurgery of the sciatic nerve in ratsPhotomicrographs showing longitudinal sections of the sciatic nerve following neurorrhaphy in the control group (A) and in the Paeonia lactiflora Pall. group (B). The sections were stained with H&E and magnified × 40. The infiltration of inflammatory cell and the parallel appearance of axons were observed in the repaired nerve. The nerve diameter of the repaired nerve (dashed line; middle portion of each photograph) was thicker than the diameter of the proximal nerve (solid line; left side of each photograph), and the measured ratio of the neuroma size was 1.4 in A and 1.0 in BBack to article page
