Exclusive Image Gallery on Human Spinal Cord Regeneration-Clinical Image-9
2019Co-Authors: Giselher SchalowAbstract:Classification scheme for human peripheral Nerve Fibers. Conduction velocities (V) and Nerve Fiber diameters (O) of afferent and Efferent Nerve Fiber groups in normal humans and in patients with a traumatic spinal cord lesion for 0.5 to 6 years. The splitting of the α1-motoneurons into the 3 subgroups, α11, α12, α13, has not yet been confirmed. This is the only existing classification scheme for human Nerve Fibers!

Transitional expression of OX-2 and GAP-43 glycoproteins in developing rat cochlear Nerve Fibers.
Histology and histopathology, 2002Co-Authors: Maria Visitación Bartolomé, Gil-loyzaga PAbstract:The OX-2 and GAP-43 glycoproteins are two proteins involved in neuronal cell-to-cell interaction and/or growing of dendrites and axons. Therefore, for the auditory receptor the expression of these proteins could provide information on the afferent and Efferent Nerve Fiber organization. The expression and distribution of OX-2 and GAP-43 were analyzed during the auditory receptor development and maturation (from embryonic day E13 to postnatal day P22). Both glycoproteins were early recognized in the cochleae of E13 rats. Then, they slowly but progressively disappeared, being absent when the animals reached the P22 postnatal day. At E13, a weak OX-2 expression was restricted to the perikaryon of the spiral ganglion neurons, while in the same period a strong GAP-43 immunostaining was found in both the neuronal perikaryon and the neurites. During the rat embryonic period (E13 to birth) the expression of both glycoproteins appeared progressively restricted to the neurites. During the rat postnatal period (P0 to P22), OX-2 and GAP-43 exhibited a dissimilar distribution pattern. The OX-2 glycoprotein appeared in the afferent, Efferent and Fibers of the auditory Nerve, while the GAP-43 glycoprotein only appeared in the Efferent Nerve Fibers. Present data suggest that OX-2 and GAP-43 could act as two complementary glycoproteins during the development, organization, and maturation of the cochlear Nerve Fibers. While both glycoproteins could participate in axonal growing and orientation, OX-2 could also be involved in a similar process for auditory dendrites.

Sympathetic Skin Response and Boston Questionnaire in Carpal Tunnel Syndrome
Інститут фізіології ім. О.О. Богомольця НАН України, 2016Co-Authors: Cevik B., Kurt S., Aksoy D.Abstract:We aimed to determine relations between the sudomotor Efferent Nerve Fiber function and Boston questionnaire (BQ) in idiopathic carpal tunnel syndrome (CTS). Median Nerve-induced sympathetic skin responses (SSRs) evoked by wrist stimulation were recorded in 108 CTS patients and compared with those in 88 healthy volunteers. The Boston questionnaire form (BQF) was applied to the subjects. All patients and healthy individuals were questioned about the autonomic symptoms in the hand (red or purple skin coloration, excessive sweating, and feeling cold). The average SSR latencies of the patients with CTS were significantly longer than those in the control group (P < 0.001). Positive significant, while weak, correlations were found between the SSR latency, autonomic symptoms, and total sympathetic system scores. No statistically significant relationship was found between the Boston symptom severity, functional capacity scores, and SSR latency. The latter obtained through wrist stimulation was sensitive to support the sudomotor sympathetic dysfunction in patients with CTS. No relationship between the BQF and SSR can be related to the fact that these indices evaluate different aspects of CTS.Ми намагалися встановити взаємовідносини судомоторної функції еферентного нерва та показників Бостонського опитувальника (BQ) у випадках ідіопатичного синдрому зап’ястного каналу (СЗК). Шкірні симпатичні відповіді (ШСВ) відводилися після стимуляції медіанного нерва на рівні зап’ястка у 108 пацієнтів із діагностованим СЗК; ці характеристики порівнювались із такими у 88 здорових добровольців. Усім суб’єктам пропонували форму BQF. Усі пацієнти та здорові особи опитувалися щодо вегетативних симптомів, які проявлялися на кисті (червоне або пурпурове забарвлення шкіри, надмірне потовиділення та відчуття холоду). Середнє значення латентного періоду ШСВ у пацієнтів із СЗК вірогідно перевищувало таке в контрольній групі (P < 0.001). Істотна позитивна, хоча й слабка, кореляція була виявлена між латентним періодом ШСВ, вегетативними симптомами та бальною загальною оцінкою стану симпатичної системи. Не було встановлено вірогідних відносин між показником тяжкості симптомів (згідно з BQF), оцінкою функціональної здатності та латентним періодом ШСВ. Останній параметр, отриманий при стимуляції на рівні зап’ястка, був чутливим щодо судомоторної симпатичної дисфункції у пацієнтів із цим синдромом. Відсутність зв’язку між оцінками BQF та ШСВ може бути зумовлена тим, що дані показники оцінюють різні аспекти ШСВ

Sympathetic Skin Response and Boston Questionnaire in Carpal Tunnel Syndrome
Neurophysiology, 2016Co-Authors: Betül Çevik, Semiha Kurt, Dürdane Aksoy, Volkan SolmazAbstract:We aimed to determine relations between the sudomotor Efferent Nerve Fiber function and Boston questionnaire in idiopathic carpal tunnel syndrome (CTS). Median-Nerve sympathetic skin responses (SSRs) evoked by wrist stimulation were recorded in 108 CTS patients and compared with those in 88 healthy volunteers.

No statistically significant relationship was found between the Boston symptom severity, functional capacity scores, and SSR latency. The latter obtained through wrist stimulation was sensitive to support the sudomotor sympathetic dysfunction in patients with CTS. As we found no relationship between the BQF and SSR, these indices may evaluate different aspects of CTS.
