PURPOSE: Traumatic brain injury is a multifaceted injury that involves direct mechanical damage, intraparenchymal and subarachnoid hemorrhage, breakdown of the blood-brain barrier, excitotoxicity, and ischemia. Even though much investigations were performed, acceptable mechanical informations were rare. The aim of this study was to reveal the expression pattern of intermediate filament proteins associated with gliotic scars in cerebral cortex of rats after cryoinjury. METHODS: A total of 18 male Sprague-Dawley rats weighing 300 g, 2 months old, were used throughout the experiments. To injure the brain, rats were anesthetized for surgery with 3.5% chloral hydrate(1 mL/100 g, intraperitoneally); the frontal bones were exposed by elevating the skin; and craniectomies were performed adjacent to the central suture, midway between lambda and bregma. A cryoinjury was then created by applying a cold probe(3-mm-diameter steel rod chilled in liquid nitrogen) to the left frontal cortex(ipsilateral cortex) for 1 min. Rats were sacrificed at 1, 4, 7 and 14 days postsurgery(n=3, per time point), and three rats were sacrificed as normal controls. Serial brain cryosections were made by cryostat. For immunohistochemistry, brain tissue sections were allowed to react with mouse anti-rat GFAP antibody(1:200), mouse anti-rat vimentin antibody(1: 200), and mouse anti-rat nestin antibody(1:200). RESULTS:Reactive astrocytes expressing GFAP, vimentin and nestin appeared for the first time at 6 hours after cryoinjury. Proliferation of GFAP and nestin positive cells started at 1 day after cryoinjury, reached its maximum on day 4, and returned to normal level after the 7th post-injured day. Proliferation of vimentin positive cells started at 1 day after cryoinjury, reached its maximum on day 4, and returned to normal level after the 14th post-injured day. Characteristic morphological changes in reactive astrocytes were seen at 4 days after cryoinjury. CONCLUSION: The above results suggest that GFAP, vimentin and nestin positive cells attend in the formation of gliotic scars.

Many researchers report that the measurement of urine calcium concentration during antenatal period is helpful in prediction of having preeclampsia,but some don`t. The purpose of this clinical study is to evaluate the relationship of low calcium level in urine and the develpoment of preeclampsia, and effects of other variables. 24hour urine were collected and measured for the concentration of calcium and creatinine from 769 pregnant women who visited our department of obstetrics at Young-Dong Severeance hospital, Yonsei university medical college for antenatal care from March 1, 1993 to May 31, 1996. One group of 41 women developed preeclampsia and the other didn`t. There were no diffrences in ages and gestational age at urine collection between two groups, but a group with preeclampsia had an increased mean arterial blood pressure. There were signiificant difference in calcium concentration in urine and ratios of concentration of calcium and creatinine from urine collected between gestational ages of 25 weeks and 32 weeks and also in those women younger than 25 years old and their first pregnancy. Our study suggests that the measure ment of calcium level and ratios of urine calcium concentration and creatinine concentration at gestational ages between 25 weeks and 32 weeks in women younger than 25 year old with their first pregnancy is quite helpful inpredicting the develpoment of preeclampsia.

Twenty-two children(4 months to 17 years old)with a clincial diagnosis of complex partial seizure(CPS) were examined with a 0.5T MRI scanner using spin-echo sequences. Eleven patients showed abnormal brain MRI findings; two had focal lesions with corresponding seizure foci on the EEG, one arising from temporal lobe(Hippocampal Formation atrophy) and the other from the frontal lobe. Nine patients showed diffuse lesions with inconsistent seizure foci on EEG. The remaining 11 patients were normal on bran MRI; two of them had normal EEG findings and the others either focal or diffuse abnormalities on EEG.

Three cases of giant pituitray adenoma are reported. Two cases were operated by transsphenoidal approach and a case by transcranial approach. Transsphenoidal approach showed satisfactory results despite of marked suprasellar extension of tumors. We report rare giant pituitary adenomas with review of relevant literatures.

The melanotic neuroectodermal tumor of infancy(MNTl) is a rare, usually benign, pigmented lesion which most frequently involves the maxilla. Skull, brain, and mandible are other craniofacial sites; this anatomic region accounts for 87% of all cases. The vast majority of MNTl, nearly 95%, present in infants of both sexes within the first year of life. Most cases of MNTl follow a benign course, with a 15% propensity for local recurrence. MNTl is regarded as a primitive neuroectodermal tumor with polyphenotypic differentiation. We report a classical MNTl which occurred in left lower maxilla in 6-month old female infant. She developed an ill defined, firm swelling on the left alveolar ridge and gum during 3 weeks. Mass excision reveals ill defined, grayish-tan hard mass, measuring 2.0x1.6 cm. Microscopically, the tumor reveals irregular alveolar pattern of melanin-containing cuboidal cells and nests of small round cells. The immunohistochemical staining for melanoma-associated antigen, neuron-specific enolase and cytokeratin show positive reactions. Ultrastructural examination showed intracytoplasmic melanosome, tonofilament and desmosome.

PURPOSE: Headache is a frequent symptom in pediatric practice, but the prevalence of chronic recurrent headache was estimated in several studies with wide variations, because of inadequate expression and differences in case definition in children. Headache classification of International Headache Society is usually used in adults, but the application of it to children is uncommon, so we tried to diagnosis children with headache by using International Headache Society Classification. METHODS: We analyzed the clinical pictures, physical examinations including neurologic examination, PNS series, EEG and CT or MRI in 53 children with nonprogressing recurrent headache over than one month, who visited to pediatric department of Dong-A University hospital from January, 1995 to Feburary, 1996 and diagnosed them by using International Headache Society Classification. RESULTS: 1) The sex ratio between male and female was 1:1.2. 2) Diagnosed groups consisted of children with migraines in 22 cases(41.5%), tension-type headache in 19 cases(35.9%), coexisting migraine and tension-type headaches in 5 cases(9.4%), miscellaneous headaches not associated with structual lesion in 1 case(1.9%), headache associated with vascular disorders in 2 cases(3.8%), headache associated with nonvascular intracranial disorder in 1 case(1.9%), headache due to facial pain in 3 cases(5.6%). 3) Of 22 migraine cases, 13 cases(59.1%) had migraine with aura, 8 cases(40.9%) have migraine without aura and of 19 tension-type headache cases, 8 cases(42.1%) have episodic type, 11(57.9%) cases have chronic type. 4) Of 53 cases with recurrent headache, 3 cases(6%) had abnormal findings in CT or MRI. 5) Of 53 cases with recurrent headache, 9 cases(17%) had abnormal findings in EEG. CONCLUSIONS: International Headache Society Classifications are useful, but the diagnostic criteria are too strict for children, especially in migraine and tension type headache.

PURPOSE: This study examined the effects of aquatic proprioceptive neuromuscular facilitation pattern exercise on the balance, gait ability, and depression in patients with chronic stroke. METHODS: Thirty patients with chronic stroke were assigned randomly to an experimental (n=15) or control (n=15) group. The experimental group performed aquatic proprioceptive neuromuscular facilitation pattern exercise. The control group performed ground proprioceptive neuromuscular facilitation pattern exercise. Training was conducted once a day for 30 minutes, five days per week for six weeks. The balance ability was measured using the Berg balance scale. The gait ability was measured using the 10 Meter walk test. Depression was measured using the Beck depression inventory. RESULTS: As a result of a comparison within groups, the experimental and control group showed a significant difference for balance, gait ability, and depression after the experiment (p<0.05). In a comparison between the two groups, the experimental group, in which aquatic proprioceptive neuromuscular facilitation pattern exercise was applied, showed more significant changes in balance, gait ability, and depression than the control group (p<0.05). CONCLUSION: Based on these results, aquatic proprioceptive neuromuscular facilitation pattern exercise effectively improved the balance, gait ability and depression in patients with chronic stroke.
