[영문]Therapeutic effect of desmopressin for nocturnal enuresis in patients with spinal cord injury This study was designed to investigate the diurnal antidiuretic hormone level and evaluate the efficacy of intranasal desmopressin inhalation on nocturnal enuresis in patients with spinal cord injuries. Forty-four adult spinal cord injuries with nocturnal enuresis were randomly assigned into the control group and the experimental group. Participants in experimental group were treated with intranasal desmopressin 10 micrograms daily at bedtime for 4 weeks, while control group were treated with placebo. Total volume of daily nocturnal incontinence and serum electrolytes were monitored every two weeks. The mean volume of nocturnal incontinence decreased significantly in the experimental group (p0.05). The group whose functional bladder capacity were greater than 350 ml showed better response, compared with the group less than 350 ml. The complications of serum electrolytes abnormalities had not occurred. Intranasal desmopressin inhalation is one of the safe and effective methods in symptomatic management of nocturnal enuresis in selected patients with spinal cord injuries.ope

[영문] This study investigated the increase or decrease of distribution and excretion of total chromium exposed simultaneously the soluble Cr+6 and Cr+3 compounds. Also, In the case of oral administrations of insoluble chromium compounds, absorption, distribution, and excretion were investigated and compared with those of oral administration of soluble chromium compounds. The results were as follows; 1. There were no difference of total chromium concentration in plasma, red bloods cells, urine, organs between simultaneously injected and individually injected soluble Cr+6 and Cr+3 compounds. 2. The chromium clearances in urine also showed that there were two phases in the two groups. In the first phase, biological half lives of the total chromium of the two groups have been similar within 24 hr., but in the second phase, biological half life of the group injected simultaneously was 62.7 hr. and was less than that of the other group's 188.3 hr. 3. In urine of the group which was administrated insoluble Cr+6 compound, average concentration of total chromium was 7.16 μ㏖/gcreatinine and was significantly increased in comparison with the control. 4. The average concentration of total chromium in plasma was same with the control, and that of RBCs was 0.218 ο½Žγ–/γŽ– and was slightly increased in comparison with 0.121 ο½Žγ–/γŽ– of the control, which was not statistically significant. 5. In case of administration of insoluble Cr+3 compound, the average concentrations of total chromium in plasma, RBCs, and urine were not increased in comparison with the control, but was only increased in feces. In case of administration of soluble Cr+6 and Cr+3 compounds, the concentration of total chromium in plasma, red blood cells, and urine were highly increased in comparison with that of administration of insoluble Cr+6 and Cr+3 compounds. As a result, there were no differences of distribution and excretion of chromium between the group exposed simultaneously and the other group exposed separately the soluble Cr+6 and Cr+3 compounds. The biological half life of chromium of the former group in urine was less than that of the other group. The result of oral administration of the high concentration of insoluble Cr+6 compound showed that the concentration of the total chromium in urine was increased. The urine sampling time was suitable within 24 hr. after oral administration of insoluble chromium. Insoluble chromium compounds were very slightly absorbed in comparison with the soluble chromium compounds.restrictio

[영문] This study was designed to compare the functional outcome of the intraspinal transplantation of neurally induced mesenchymal stem cells and that of mesenchymal stem cells in the rat model of spinal cord injury. Sprague-Dawley rats were anesthetized and subjected to the spinal cord injury model. The rats had undergone the free drop contusion spinal cord injury at a lower thoracic level. An incomplete spinal cord injury was induced using the NYU impactor. Mesenchymal stem cells were obtained from bone marrow of rats. To induce neural differentiation, a basal medium was replaced with Dulbecco's modified eagle medium and fetal bovine serum supplemented with fibroblast growth factor. The rats were randomly assigned into 3 groups. Rats in the control group were injected phosphated buffer saline instead of cell transplantation. Rats in the mesenchymal stem cell transplanted group were injected mesenchymal stem cells into the spinal cord. Rats in the neurally induced mesenchymal stem cell transplanted group were injected neurally induced mesenchymal stem cells into the spinal cord. Functional outcomes were measured using the Basso-Beattie-Bresnahan locomotor rating scores and an electrophysiologic study. The Basso-Beattie-Bresnahan locomotor rating scores were checked every week. A somatosensory evoked potential study and a motor evoked potential study were performed 9 weeks after the spinal cord injury. When the Basso-Beattie-Bresnahan locomotor rating scores were compared among the 3 groups, the neurally induced mesenchymal stem cell transplanted group showed a significant improvement. In the somatosensory evoked potential study, the rats in the neurally induced mesenchymal stem cell transplanted group showed significantly shortened initial latency, N1 latency and P1 latency compared with other groups. The neurally induced mesenchymal stem cells transplanted into the rats improved the hind limb performance and shortened latency of a somatosensory evoked potential study. Transplanting neurally induced mesenchymal stem cells may play an effective role in promoting the functional recovery. These results suggest that the proper choice of the stem cells for transplantation could provide the most efficient functional recovery after spinal cord injury.ope
