OBJECTIVE: Recently, we have demonstrated that embryonic ventral spinal cord motor neurons(ESMNs), transplanted into the distal stump of the axotomized tibial nerve, can grow into the denervated gastrocnemius muscle and form neuromuscular junctions. Our interest in study was to see whether these newly formed neuronal connections are physiologically active, and to electrophysiologically characterize the reinnervated motor units. MATERIAL AND METHODS: Three to eight weeks after transplantation rats were prepared for electrophysiological recording. Motor unit (MU) action potential and gross EMG were monitored. In eleven out of sixteen transplanted animals single unit and gross EMG were recorded after electrical stimulation of the transplant site. Total of 63 motor units were analyzed for their stimulus threshold (ST), latency and stimulus intensity, which is required to produce maximum firing. RESULTS: ST intensities activating MUs were significantly higher in transplanted animals than in controls. Maximum firing of MUs occurred at less than 1.2×T in the control but greater variation was observed in the transplanted animals ranging from 1.1×T to 1.6×T. No significant differences were found in the latencies of MU's firing following stimulation. MU firing was reversibly blocked by infusion of succinylcholine. CONCLUSION: we characterized the temporal, morphological and electrophysiological parameters of denervated skeletal muscle reinnervated by dissociated grafts of embryonic ventral spinal cord cells. MUs reinnervated by the embryonic motoneuronal transplant were physiologically active, with some properties similar to the MUs of the normal.

BACKGROUND: To know the effect of droperidol and ondansetron on nausea and sedation in postoperative patients, we studied 120 gynecological patients receiving patient-controlled analgesia (PCA) with morphine and droperidol or ondansetron. METHODS: Subjects were randomly allocated to one of four groups according to PCA regimen, morphine 0.5 mg/cc alone (group M); morphine plus droperidol 0.034 mg/morphine 1 mg (group D); morphine plus ondansetron 0.132 mg/morphine 1 mg (group O1); morphine plus ondansetron 0.066 mg/morphine 1 mg (group O2). The PCA device, WalkMed was set at basal rate 2 ml/hr (1 mg/hr), bolus dose 1 ml (0.5 mg), lockout time 10min, 1 hour maximum dose 4 mg. The severity of nausea, sedation and pain were assessed at 1h, 4h, 8h, 12h, 24h, and 48h postoperatively. RESULTS: The occurrence of nausea was not different among groups. But there were statistical differences in the nausea severity (p<0.05). The group D and group O1 had lower nausea scores, and between them there was no difference. The scores for sedation were significantly lower in the group O1 compared with group M and group D (p<0.05). Overall pain scores were not different among groups. CONCLUSIONS: Ondansetron and droperidol are effective in reducing nausea. Ondansetron is superior to droperidol in avoiding excessive sedation.

The depth from the skin to the thoracic epidural space was measured in 121 patients (41 male and 80 female patients) receiving epidural analgesia. The patients age, sex, height, weight were obtained before measuring the distance. The needle angle to the vertical axis to the skin was obtained during inserting Touhy needle. The mean depth was 6.0+/- 1.3 cm, which correlated with other anatomic measurements except height. The depth was correlated with the needle angle. The group with needle angle greater than 30(0) was greater in depth than the other groups. The mean depth was 6.0+/-1.4 cm in males and 6.0+/-1.3 cm in females and there was no difference in depth between male and female. The mean depth was 5.7+/-1.3 cm at the T5-6 interspace and 6.2+/-1.3 cm at the T6-7 interspace and there was no difference in depth between the two groups.
