This study evaluated an implantable electrical stimulator using a sciatic nerve injury animal model, and ethological, electrophysiological and histological assessments. Forty Sprague-Dawley rats were used in the study, and were subjected to crushing of the right sciatic nerve with a micro-vessel clamp. Electrical stimulators were implanted in twenty of the rats (the implantation group), while t...

[Purpose] The purpose of this study was to investigate the effects of treadmill training on functional recovery by analyzing the ankle joint as well as the knee and hip joints with 2D video analysis during gait by rats with sciatic nerve injury. [Subjects and Methods] Twenty-four male Sprague-Dawley rats were used in this study. The sham group (SG) received only a sham operation without any sci...

Sciatic functional index (SFI) as a behavioral method was used to assess the functional recovery following experimentally-induced various injuries in the sciatic nerve, spinal cord, and brain. In the present study, the functional recovery after induction of injury in the sciatic nerve was investigated in rats using SFI. Twenty-four rats were divided into three groups including sham-operated (SS...

to evaluate the effects of local administration of the fetal brain extract (fbe) on the crushed peripheral nerve, 15 male wistar rats were used. the right sciatic nerve of 10 rats was locally underwent the tense compression for 30 seconds and then randomly divided into experimental and control (sham) groups. the remained rats were considered as intact animals. treatment was commenced weekly, by...

Cell migration is central to development and post-traumatic regeneration. The differential increase in 6-sulphated chondroitins during axonal growth in both crushed sciatic nerves and brain development suggests that chondroitin 6-sulphotransferase-1 (C6ST-1) is a key enzyme that mediates cell migration in the process. We have cloned the cDNA of the C6ST-1 gene (C6st1) (GenBank accession number ...

Background: Many people suffer from nerve injury. The time consuming nature of the treatments makes the condition worse. Therefore, finding a way to accelerate the process of nerve repair is very important.Objective: To determine the effect of ultrasound on the acceleration of crushed peripheral nerve regeneration.Methods: The experimental model included crushed rat’s sciatic nerve. 40 rats w...

gonadotropin-releasing hormone (gnrh) has neuromodulatory roles in central and peripheral nervous systems. the purpose of this study is to evaluate the effect of gnrh analog (buserelin) on peripheral nerve regeneration. forty adult male rats were divided into buserelin-treated, normal saline, sham surgery, and castrated + buserelin groups. the left sciatic nerve was crushed by a fine forceps an...
