“…The segments of the left PPN and the L6VR distal to the coaptation site in end-to-side neurorrhaphy group were also harvested and cut into ultrathin sections, and stained with uranyl acetate and lead citrate for ultrastructure observation [17]. Total nerve fiber counts were calculated with the aid of automated digital analysis software, Image-pro plus version 6.0 for windows (Image-pro, Meida Cybernetics, USA) [18,19]. The semi-thin sections were observed under light microscope and the ultrathin sections were observed under transmission electron microscope (Tecnai G2, The Netherlands).…”

“…The vagus nerve is a mixed cranial nerve that consists of 80% afferent fibers innervating the heart, aorta, lungs and gastro intestinal tract and 20% efferent fibers that provide parasympathetic innervations of these structures and innervate the voluntary striated muscles of the larynx and pharynx through the recurrent laryngeal nerve, which is similar in rats (Dahlqvist et al, 1982;Paxinos, 2004) and humans (Berthoud and Neuhuber, 2000;Jotz et al, 2011). Moreover, the proportion of myelinated axons in the 0165-0270/$ -see front matter © 2011 Elsevier B.V. All rights reserved.…”

“…The regenerative PPNs distal to coaptation were prepared for semi-thin cross-sections with a thickness of 0.5-1 lm and were cut using an ultramicrotome (Ultracut UCT, Leica, Germany) from the middle of the harvested PPNs, and stained with 1% TB for morphological examination. The microscopic images were digitized on a gray scale using automated digital analysis software (Image-Pro Plus 6.0, Media Cybernetics, USA) to calculate the axon amount in all fields of the sections ( Jotz et al, 2011;Liao et al, 2009;Vaitkeviciene et al, 2006). The axons' number of PPNs originating from donor somatic nerve were also calculated by axon counting of the semi-thin section.…”

End-to-side neurorrhaphy is widely used in the peripheral nervous system for nerve repair; however, the application of this technique has been limited to somatic nerves. The feasibility of nerve regeneration through end-to-side neurorrhaphy between autonomic and somatic nerves with different characteristics in the peripheral nervous system is still undetermined. In this study, rats were divided into three groups for different treatments (n = 10 per group). In the end-to-side neurorrhaphy group, left L6 and S1 were transected in the dura, and the distal stump of L6 ventral root was sutured to the lateral face of L4 ventral root through end-to-side coaptation. In the no repair group, the rats did not undergo neurorrhaphy. In the control group, the left L6 dorsal root and S1 roots were transected, respectively, but the L6 ventral root was kept intact. After 16 weeks, the origin and mechanism of nerve regeneration was evaluated by retrograde double labeling technique as well as histological examination and intravesical pressure measurement. Retrograde double labeling indicated that the reconstructed reflex pathway was successfully established and the primary regeneration mechanism involved axon collateral sprouting. Morphological examination and intravesical pressure measurement indicated prominent nerve regeneration and successful re-innervation of the bladder in the neurorrhaphy group, compared with the ''no repair'' group ( p < 0.05). No significant changes were observed in the histology of the donor nerve and the bilateral extensor digitorum longus muscles in the neurorrhaphy group. Nerve regeneration may be achievable for nerve repair through end-to-side neurorrhaphy between autonomic and somatic nerves without apparent impairment of donor somatic nerve.
