Background: Peripheral nerves may be damaged during an injury and its current standard treatment is using an autologous nerve. Objectives: The purpose of this experimental study is to evaluate and compare the histological results of nerve regeneration after using the eggshell membrane (ESM) guidance channel with autograft. Materials and Methods: Thirty adult male rats were divided into th...

Using immunocytochemistry, the authors studied the peptidergic innervation to the vasculature of the optic nerve and retina in the rhesus monkey and rat. In the monkey, beaded nerve fibers immunoreactive to the vasoactive peptides, calcitonin gene-related peptide (CGRP), neuropeptide Y (NPY), substance P (SP), and vasoactive intestinal peptide (VIP), are present in the adventitia and perivascul...

Basic fibroblast growth factor (bFGF) and nerve growth factor (NGF) were administered into the rat brain following unilateral fimbria-fornix transection. Both bFGF and NGF stimulated the sprouting of acetylcholinesterase (AChE) positive fibers in the hippocampus on the lesioned side. Furthermore, a small number of AChE-positive fibers were regenerated even when only the vehicle was administered...

The enteric nervous system (ENS) is essential for normal motility and many other physiologic properties of the gastrointestinal tract.1 It is composed of intrinsic neurons, the cell bodies and most processes of which are located inside the bowel wall, and extrinsic nerve fibers that project into the gut from autonomic and sensory ganglia. Although extrinsic innervation modulates the activity of...

Several lines of evidence indicate that neurofilaments are major intrinsic determinants of axonal caliber in myelinated nerve fibers, and that the delivery of neurofilaments by slow axonal transport is an important mechanism by which neurons regulate axonal caliber. To further clarify the relationship between neurofilament transport and axonal caliber, we examined transport in developing motor ...

abstract introduction: interferential current is one of the most popular kinds of electrical stimulation that are used in electrotherapy. despite its clinical popularity, there have been limited studies to investigate how this stimulation protocol affects the nerve fibers. this study was aimed to develop a realistic model for the stimulation of nerve fibers by interferential currents and using ...

A method is evolved whereby the after-potential sequence intrinsic to longitudinal dorsal column myelinated fibers may be studied in isolation from those events occurring in intact spinal cord subjected to an afferent volley. The recovery sequence intrinsic to dorsal column fibers, after refractoriness is over, is characterized by supernormality approximately four to five times greater than tha...

Background Endometriosis is a common, benign, oestrogen-dependent, chronic gynaecological disorder associated with pelvic pain and infertility. Some researchers have identified nerve fibers in endometriotic lesions in women with endometriosis. Mesenchymal stem cells (MSCs) have attracted interest for their possible use for both cell and gene therapies because of their capacity for self-renewal ...
