  • This study was aimed to charily the change of NADPH-diaphorase(NADPH-d) and neuropeptide Y(NPY) associated with aging of the rots. To verily the effect of aging of NPY and NADPH-d-positive neurons in the brain stem, the neurons were stained by the immunohistochemical and histochemical method. In the aged group, the number of NADPH-d-positive neurons was significantly decreased in substantia nigra lateralis, supragenual nucleus, raphe magnus nucleus and raphe obscurus nucleus as compared with control group. The number of NADPH-d-positive neurons was not significantly decreased in superior colliculus, interpeduncular nucleus, central gray. dorsal raphe nucleus, retrorubral nucleus, pedunculopontine tegmental nucleus, laterodorsal tegmental nucleus, pontine reticular nucleus, prepositus hypoglossal nucleus and nucleus solitarius of the aged rats. The NADPH-d and NPY-positive neurons were found in the interpeduncular nucleus, central gray, substantia nigra lateralis, laterodorsal tegmental nucleus, nucleus solitarius, raphe magnus nucleus, raphe obscurus nucleus of the control and aged groups. The coexistence of NADPH-d and NPY in the some cell was not found in the brain stem of both groups.

  • Clinical observation was made on 210 cases of CVA that were confirmed through brain CT, MRI scan and clinical observation. They were hospitalized in the oriental medical hospital of Kyungwon University from January to December in 1998. Objective : To evaluate the current status of cerebrovascular disease in Korea, we performed observation on stroke patients. Methods : We performed a retrospective study on 210 cases of stroke who had been admitted to the Dept. of Internal Medicine, College of Oriental Medicine, Kyungwon University from Jan. 1, 1998 to Dec. 31, 1998. Results : The incidence was highest in the patients with the age of above fifty. The frequency of strokes was similar between male and female cases. Ischemic stroke(70.0%) was more common than hemorrhagic stroke(20.5%), with transient ischemic attacks(9.5%) occuring less frequently. Middle cerebra! arterial territory was the most commonly involved site in ischemic strokes. Among intracerebral hemorrhages, putaminal hemorrhages were found in 69.8%, and was followed by IVH(9.3%), IVH with ICH(7.0%), subcortical hemorrhages (4.7%) and pontine hemorrhages(4.7%). The most ordinary preceding disease was hypertension. The next was diabetes mellitus. Most cases were given simultaneous treatment in both western and oriental medical methods. Conclusions : Generally it is thought that CVA occurs frequently in winter. But our observations reveal no such relationship. The predisposing factors of cerebral infarction were usually initiated during the time of resting and sleeping and those of cerebral hemorrhage chiefly during the time of exercising. I Patients whose condition of consciousness was bad at the time of admission tended to have a bad prognosis. This study suggests changing trends of stroke in Korea, and that a multicenter prospective study using stroke registry is required for confirmation.

  • Apenetrating head injury by an arrow is extremely rare being only two cases reported in the literature. We report a case of 12-year-old boy who presented with an arrow lodged at the posterior fossa through nasal nostril. He was slightly drowsy, but neurologically intact except a sixth nerve palsy in the left eye. Brain CT showed no intracerebral hemorrhage. The arrow was entered through the right nostril and the tip was stucked in the left cere-bello-pontine angle through the sphenoid sinus. We removed the arrow without craniotomy since the tip was verified smooth and no cerebral arteries were in contact with the arrow. The patient recovered well without any significant complications. The sixth nerve palsy resolved completely after six months. The verification of the shape of the offending material, a retrograde removal of the arrow in the direction of its line of trajectory, and an identification of adjacent cerebral arteries seem to be important in the management of this type of injury.

  • It is rare for low-grade gliomas to disseminate to the leptomeninges. However, low-grade gliomas with dissemination to the leptomeninges have been occasionally reported in children, and have generally been associated with local recurrence. A 16-year-old boy sought evaluation for diplopia and gait disturbance. A brain magnetic resonance imaging (MRI) revealed pontine mass, which was proved to be fibrillary astrocytoma on biopsy, later. Radiation therapy (5400 cGy) was given and the patient's symptoms were improved. He was followed-up radiologically for brain lesion. Seven months after diagnosis he complained of back pain and gait disturbance. A brain MRI showed a newly-developed lesion at the left cerebellopontine angle without an interval change in the primary lesion. A spinal MRI demonstrated leptomeningeal dissemination of the entire spine. Radiation therapy (3750 cGy) to the spine, and adjuvant chemotherapy with a carboplatin plus vincristine regimen were administered. However, he had a progressive course with tumoral hemorrhage and expired 13 months after diagnosis. We report an unusual case of a low-grade brainstem glioma with spinal dissemination, but without local recurrence, and a progressive course associated with hemorrhage.

  • Stress urinary incontinence (SUI) is a common condition that primarily affects women. Here, we investigate the effects of human adipose-derived stem cells (ADSCs) in a rodent model of SUI. Female Sprague-Dawley rats at 7 weeks of age were randomly divided into three groups (n=8 per group): sham-operation, SUI-induction by transabdominal urethrolysis, and SUI-induction followed by transplantation of human ADSCs into the urethra. The abdominal leak point pressure at 8 weeks after the operation was markedly decreased by transabdominal urethrolysis, confirming successful induction of SUI. Interestingly, transplantation of human ADSCs into the urethra significantly blunted the decrease of abdominal leak point pressure in SUI-induced rats. Accordingly, we observed expression of ${\alpha}$-smooth muscle actin in a significant proportion of transplanted ADSCs, indicating differentiation of ADSCs into smooth muscle cells in the urethra. Moreover, the SUI-induced elevations of c-Fos immunoreactivities in the pontine micturition center (PMC) and in the ventrolateral periaqueductal gray (vlPAG) were clearly suppressed by transplantation of human ADSCs. These results imply that human ADSCs can be an effective therapeutic modality to ameliorate the symptoms of SUI.

  • Objective: The purpose of this case study is to report the effectiveness of Baliao acupoints electro-acupuncture treatment on a neurogenic overactive bladder induced by stroke. Method: A patient suffering from middle cerebral artery infarction was diagnosed with a neurogenic overactive bladder and treated by Korean medicine, including electro-acupuncture on Baliao acupoints six times per week. The evaluation was performed by monitoring urinary frequency and using the Korean versions of the Overactive Bladder Symptom Score (OABSS) and Urinary Incontinence Quality of Life (I-QoL). Results: After 27 days of electro-acupuncture treatment, the OABSS score improved from 6 to 3. The I-QoL total score improved from 60 to 87. The patient also showed a decrease in nocturia frequency. Conclusion: This case suggests that electro-acupuncture on Baliao acupoints can be effective for overactive bladders due to supra-pontine lesions.

  • Objectives : The purpose of this morphological studies was to investigate the relations between Sanyinjiao(Sp6), Yinlingquan(Sp9) and pancreas of rats using peudorabies virus(PRV). Methods : We observed labeled neurons following the injection of PRV, Bartha strain, into the Sanyinjiao(Sp6), Yinlingquan(Sp9) and pancreas of rats. After survival times of 4 days following the injection of PRV, the rats were perfused, and their spinal ganglia, spinal cord and brain stem were frozen sectioned($35{\mu}m$). These sections were strained by PRV immunohistchemical staining methods and observed with light microscope. Results : The results were as follows. 1. In the spinal ganglia, the overlap areas of PRV labeled neurons projecting to Sanyinjiao(Sp6), Yinlingquan(Sp9) and pancreas were observed in T10-13 dorsal root ganglia. 2. In the spinal cord, the overlap areas of PRV labeled neurons projecting to Sanyinjiao(Sp6), Yinlingquan(Sp9) and pancreas were lamina I, IV, V, VII, IX, X, intermediolateral nucleus(IML), intermediomedial nucleus(IMM) in thoracic segments. In lumbar segments, the overlap areas of PRV labeled neuron were lamina I, IV, V, VI, IX, X and IMM. In sacral segments, the overlap areas of PRV labeled neuron were lamina I, IV, V, VI, VII, IX, X. 3. In the brain, the overlap areas of PRV labeled neurons projecting to Sanyinjiao(Sp6), Yinlingquan(Sp9) and pancreas were area postrema, nucleus tractus solitarius, caudoventrolateral reticular nu., medullary reticular nu., lateral paragigantocellular nu., C3 adrenalin cells, gigantocellular nu., raphe pallidus nu., raphe obscurus nu., ambiguus nu., raphe magnus nu., pontine reticular formation, A5 cell group, subcoeruleus nu., locus coeruleus, Barringnton's nu., $K{\ddot{o}}lliker$-Fuse nu., dorsal raphe nu., Edinger-Westphal nu., central gray matter, perifornical nu., dorsomedial hypothalamic nu., arcuate nu., lateral hypothalamic nu., paraventricular hypothalamic nu., hindlimb area. Conclusions : In conclusion, these results suggest that the interrelationship of meridian(spleen meridian), acupoints(Sp6 and Sp9) and viscera(pancreas) may be related the central autonomic centers.

  • Objective : This study investigated the alteration of neural activity and effect of Yanggyuksanhwa-tang (Lianggesanhuo-tang) on cerebral ischemia of rats. Methods : Considering age-related impact on cerebral ischemia, aged rats (18 months old) were used for this study. Ischemic damage was induced by the transient occlusion of bilateral common carotid arteries (BCAO) with hypotension. Yanggyuksanhwa-tang (Lianggesanhuo-tang) was administered twice a day orally. Then alterations of neural activities in the brain of aged BCAO rats were measured by the [$^{14}C$]2-deoxyglucose autoradiography method. Results : The BCAO in aged rats led to significant decrease of neural activity in the whole brain. Treatment with Yanggyuksanhwa-tang (Lianggesanhuo-tang) significantly attenuated the decrease of neural activity in the whole brain following BCAO ischemia. Treatment significantly attenuated the decrease of neural activity in the CA1, CA2, CA3, dentate gyrus of the hippocampus, activated barrel, barrel cortex, somatosensory cortex, cingulate cortex, caudate putamen, and medial septal nucleus following BCAO in aged rats. Treatment with Yanggyuksanhwa-tang (Lianggesanhuo-tang) also significantly attenuated the decrease of neural activity in the anteroventral thalamic nucleus, ventral anterior thalamic nucleus, arcuate nucleus, posterior hypothalamic area, medial mammillary nucleus, lateral periaqueductal gray, dorsal raphe nucleus, interpeduncular nucleus, median raphe nucleus, and medial pontine nucleus. Conclusion : It can be suggested that Yanggyuksanhwa-tang (Lianggesanhuo-tang) has a neuroprotecuve effect on cerebral ischemia through the control of glucose metabolic rate and cerebral blood flow.
