Background: Olfactory ensheathing glia (OEG) has been shown to have a neuroprotective effect after being transplanted in rats with spinal cord injury. This study was conducted to determine the possible beneficial results of olfactory mucosa transplantation (OMT) which is a source of OEG on functional recovery and axonal regeneration after transection of the sciatic nerve. Methods: In this study...

Introduction: Cell transplantation is one of the main strategies for spinal cord injury repair. As OECs of the olfactory mucosa can be obtained by simple biopsy in all individuals without affecting their smell sensation, OECs considered as a promising candidate for autologous transplantation in the nervous system injury, especially for spinal cord repair. Thereby in the current study OECs wer...

Object: The inability of the spinal cord to regenerate after SCI is due to the extremely limited regenerative capacity of most central nervous system (CNS) axons, along with the hostile environment of the adult CNS, which does not support axonal growth. It seems that for successful axonal regeneration to take place, a supportive local environment is required after the injury. We have previously...

Carlos Lima et al. who are pioneers in this field reported their clinical pilot study of olfactory mucosa transplantation for chronic spinal cord injury. They showed the safety and feasibility of it. Olfactory mucosa contains the olfactory ensheathing cells and neural stem cells. Recent studies have demonstrated the potential therapeutic role of both cells in spinal cord injury. We have already...

1. Prussian blue particles pass rapidly from the surface of the olfactory mucosa and within 2 minutes are found in the tissue spaces, in blood and lymph vessels, in the perineural spaces of the olfactory nerve fibers and in the subarachnoid space and pia-arachnoid membrane. 2. There is great affinity of pigment particles for the olfactory sensory cells. 3. Preliminary treatment of the olfactory...

organization of various cells lining the olfactory mucosa of puntius ticto (hamilton, 1822) were described by light as well as scanning electron microscopy. the paired olfactory chambers located antero-dorsal to the eyes and communicated outside through anterior and posterior nasal openings. the oval shaped olfactory rosette lied at the bottom of chamber and composed of 18-20 lamellae arranged ...

medicina fluminensis 2016, Vol. 52, No. 1, p. 43-48 43 Abstract. Olfactory rehabilitation after a laryngectomy is based on establishing nasal airflow to allow odorant molecules to come into contact with the olfactory mucosa. Currently, the polite yawning technique (PYT) is the gold standard for post-laryngectomy olfactory rehabilitation, but it is usually introduced in patient’s rehabilitation ...

Most physiological studies of the human olfactory system have concentrated on the cortical level; the olfactory bulbar level has been studied rarely. We attempted to stimulate the human olfactory mucosa by electrical pulse to detect the bulbar potentials. Electrical stimulation (2 mA, 0.5 ms) of the human olfactory mucosa evoked a change in potential recorded from the frontal sector of the head...
