In order to differentiate the effects of STT on spinal interneurones and motoneurones, changes in monosynaptic (MR), polysynaptic (PR1, PR2) and flexion (FR) reflex responses of L5 ventral root after STT microinjections into the dorsal or ventral horn of the spinal cord were studied in the rat. MR, PR1 and PR2 were evoked by high threshold stimulation of the dorsal root and FR by subcutaneous stimulation of hind paw. Microinjections of STT (10, 50, 100 µM in 0.5 µL) reversibly depressed PR1, PR2 and FR when injected either into the dorsal or ventral horn. 500 µM STT depressed PR1 and PR2 after injected into the dorsal horn, whereas STT at 500 µM concentration evoked facilitation of PR1 and PR2 when administered into the ventral horn. STT-evoked depression of PR2 and FR was accompanied by a reduction in duration and an increase in latency. STT did not induce considerable changes in MR in present experiments. Our data have shown that intrasegmental STT administrations did not significantly influence spinal motoneurones, but provided evidence that interneuron are the main group of cell-target for STT, a finding which is in line with the previous evidence that STT may modulate transmission of the secondary signals in the spinal cord.Öğe Neuromuscular effect of pipecuronium bromide(1994) Ozzeybek D.; Elar Z.; Celebi G.; Tutan A.'Onset of action', 'duration of action', 'recovery index' and 'reversibility with anticholinesterases' of pipecuronium bromide, a new muscle relaxant, were studied on 24 cases with ASA physical status 1 who received thiopental, N2O-O2 and isoflurane anesthesia. Neuromuscular function was monitored with mechanomyography (MMG) and train-of-four (TOF) stimulation model of 3 groups each containing 8 patients; group I was given 70 µg.kg-1; group II 85 µg.kg-1 and group III 100 µg.kg-1 pipecuronium bromide. There was no statistically significant difference between 3 groups on the basis of 'onset of action' which was found to be 2.7 min; 2.8 min, 2.2 min in the groups I, II and III, respectively (p > 0.05). Statistically significant difference between groups on the basis of 'duration of action' which was found to be 73.3 min in the group I, 77.1 min in the group II and 104.8 min in the group III, was recognized to be due to the significantly longer action of the agent on 100 µg.kg-1 dose group (p < 0.01). 'Recovery index' and % T1 values before and 2, 5, 8 and 10 min after decurarization showed no statistically significant difference between groups (p > 0.05). TOF ratios before decurarization which were found to be 10.1% in the group I, 20.3% in the group II and 10.0% in the group III showed statistically significant difference between groups (p < 0.01). According to data obtained from this study, it was concluded that: by using the suggested doses for clinical practice, action of pipecuronium bromide, which started in 2-3 min and lasted 73-105 min, might be easily reversed by anticholinesterases (reversal time being dose dependent) and might be preferred for surgical procedures especially requiring long periods of muscle relaxation.Öğe Prevention of neurovascular complications in extension osteotomy of the tibia in poliomyelitis(Springer-Verlag, 1991) Celebi G.; Kurt R.; Lok V.; Sebik A.; Barin E.; Zeren B.Extension osteotomy of the proximal tibia was carried out in patients with quadriceps weakness after poliomyelitis in order to obtain a stable knee during the stance phase. Blood flow in the anterior and posterior tibial arteries was measured by Doppler sonography before, during and after operation. It was found that there was a correlation between the degree of extension of the knee after operation and a diminished blood flow. This probably explains some of the neurovascular complications reported in the literature after this procedure. We recommend that blood flow is monitored sonographically in the postoperative phase and that optimum extension is obtained gradually over a period of time in a hinged plaster cast. © 1991 Springer-Verlag.Öğe The role of stimulus modality and response condition on human event related potentials(1981) Celebi G.[No abstract available]
