objective: to assess the neuroprotective effects of local administration of 17- beta- estradiol on nerve regeneration. methods: sixty female wistar rats were overiectomized and divided into four experimental groups (n = 15), randomly: in autograft group a segment of sciatic nerve was transected and re-implanted reversely. in sham-surgery group sciatic nerve was exposed and manipulated. in trans...

INTRODUCTION Dexamethasone and vitamin B(12) are currently used in the clinic to treat peripheral nerve damage but their mechanisms of action remain incompletely understood. In this study we hypothesized that dexamethasone and vitamin B(12) promote the production of endogenous neurotrophic factors, thereby enhancing peripheral nerve repair. MATERIAL AND METHODS Ninety-six adult male Wistar ra...

BACKGROUND Total hip arthroplasty (THA) is an established treatment for end-stage arthritis, congenital deformity, and trauma with good long-term clinical and functional outcomes. Delayed sciatic nerve injury is a rare complication after THA that requires prompt diagnosis and management. METHODS We present a case of sciatic nerve motor and sensory deficit in a 52-year-old patient 2 years afte...

Objective- Comprehensive functional, histomorphometrical and immunohistochemical assessment of sciatic nerve regeneration through an inside-out vein graft in rat. Design- Experimental in vivo study. Animals- Fifty- four healthy male White Albino rats. Procedures- The rats were divided into three experimental groups (n=18), randomly: Sham-operation (NC), Transected control (TC) and Inside-out ve...

The stimulation of peripheral nerve regeneration has been studied in different ways, including the use of electrical fields. The capacity of this modality to enhance nerve regeneration is influenced by the parameters used, including current type, frequency, intensity, and means of administration. Transcutaneous electrical nerve stimulation (TENS) is a frequently used form of administering elect...

INTRODUCTION Repair of peripheral nerve injuries is an intensive area of challenge and research in modern reconstructive microsurgery. Intensive research is being carried out to develop effective alternatives to the standard nerve autografting, avoiding its drawbacks. The aim of the study was to evaluate the effectiveness of a newly designed mechanical device for the reconstruction of the sciat...

Peripheral neuropathy is associated with chronic debilitating pain and difficult to treat. In this regard, the development of cell therapy neuropathic using adipose-derived mesenchymal stem cells (MSCs) seems be relevant. The work was devoted study impact allogeneic MSC transplantation on nociceptive reactions in response mechanical thermal stimuli gait parameters rats sciatic nerve injury. It ...

INTRODUCTION Previously, we introduced the biogenic conduit (BC) as a novel autologous nerve conduit for bridging peripheral nerve defects and tested its regenerative capacity in a short- and long-term setting. The aim of the present study was to clarify whether intraluminal application of regeneration-promoting glial cells, including Schwann cells (SC) and olfactory ensheathing cells (OEC), di...

objective: transplantation of bone marrow stromal cells (bmscs) or schwann cells (scs) can facilitate axonal regeneration in peripheral nerve injuries. the aim of this study was to compare the effects of transplantation of bmscs and scs on functional recovery after injury to the sciatic nerve in the rat. materials and methods:in this experimental research, adult male wistar rats (n=24, 250-300 ...

Objective: The aim of our study was to investigate the effect of decimeter waves on nerve healing in a rat peripheral nerve injury model. Method: Twenty-four hours after the operation, the experimental group (40 rats) was treated with decimeter waves. Another 40 rats that did not undergo decimeter wave therapy were assigned as the control group. Gross and light microscopy assessments were perfo...
