2.Morphometric Study of the Thickness and the Angles of Long Axes of the Vertebral Laminae of Korean Adults.
Korean Journal of Physical Anthropology 1996;9(2):117-122
Few morphometric data on the thickness and the inclination of vertebral lamina are found with its frequent involvement in many surgical procedures. The thickness in the middle of right vertebral lamina and the angle between the superior border of lamina and sagittal plane were measured in 90 dried vertebral columns. 1. The laminae of the cervical vertebrae were generally thin and they became gradually thicker down to the lumbar vertebrae. The lamina of the fifth lumbar vertebra was the thickest (9.4mm) and that of the fifth cervical was the thinnest (2.9mm). The thickest lamina appeared in second cervical, twelfth thoracic and fourth lumbar vertebrae in 71%, 44% and 36%, respectively. 2. The angles between superior border of long axes of the laminae and the sagittal plane were the widest in thoracic vertebrae, and narrower in lumbar, the narrowest in cervical vertebrae. The angle of eithth thoracic was the widest (59.8°) and that of the fifth lumbar was the narrowest (48.6°). Widest angle of lamina appeared in seventh cervical, sixth thoracic and fifh lumbar vertebra in 27%, 20% and 48%, respectively. 3. No significant differences were found in the thicknesses and the angles of inclination of vertebral laminae between males and females.

OBJECTIVE: To assess the difference of baseline hormonal status and pathophysiology, and confirm the risk factors for long term complication according to Body Mass Index in women with polycystic ovary syndrome. MATERIALS AND METHODS: Serum level of LH, FSH, Estradiol, Prolactin, Testosterone, DHEA-S, fasting insulin were measured and 100 gm oral glucose tolerance test and endometrial biopsy were performed in total 75 chronic anovulation patients and 20 normal cycling infertility patients. 95 evaluated patients were divided into 3 groups including patients with chronic anovulation having BMI below 25, BMI beyond 25.1, normal cycling infertility patients, Group 1 (n=39), Group 2 (n=36), Group 3 (n=20), respectively. Statistical analysis was performed respect to relationship between BMI and measured hormone level, sum of glucose level during 100 gm OGTT, insulin resistance using t-test, ANOVA test, Post Hoc test, Mann-Whitney test. p<0.05 was considered as statistically significant. RESULTS: Serum LH level and LH/FSH ratio was significantly higher in Group 1, compared than Group 2 or 3 (p<0.05), BMI and LH, LH/FSH ratio was negatively correlated (r=-0.351, r=-0.318). There was no significant difference according to BMI in FSH, testosterone, estradiol, prolactin, DHEA-S level. Fasting insulin and sum of glucose level during 100 gm OGTT were significantly higher in Group 2 compared than Group 1 or Group 3 (p<0.05), there was no significant difference between Group 1 and Group 3. Insulin resistance was more frequently identified in Group 2 compared than Group 1 (p=0.001). CONCLUSIONS: BMI and LH, LH/FSH ratio were negatively correlated, so clinical significance of LH, LH/FSH ratio in diagnosis of PCOS may be attenuated by increasing body weight. Overweight patients with chronic anovulation may be the risk group for developing insulin resistance, hyperinsulinemia, glucose intolerance, later type 2 DM. Hyperinsulinemia may operate mainly in overweight chronic anovulation patients in development of hyperandrogenism.

4.Enteric Cyst in the Tongue.
Korean Journal of Pathology 1997;31(11):1237-1239
A case of enteric cyst in the anterior two-thirds of the tongue is reported. The patient, a 42 day-old female infant, presented with a protruding tongue mass since birth. Under the impression of ectopic thyroid gland or leiomyoma, complete resection was performed. The mass proved to be an enteric cyst, lined by small intestinal mucosa with an underlying coat of smooth muscle. Enteric cysts arising in the tongue is rare and only 8 such cases have been reported in the literature.

6.Electroencephalographic Findings in Moyamoya Disease.
Journal of the Korean Child Neurology Society 1997;5(1):76-85
BACKGROUND: "Rebuild-up" phenomenon, induced by hyperventilation, is a characteristic finding on EEG in children with Moyamoya disease. Its mechanism, however, remains obscure. In this study, we examined the relationship between cerebral lesions on MRI, stenosis or occlusion of cerebral vessel on cerebral angiography, and EEG findings in children with Moyamoya disease. METHODS: We have reviewed medical records of 33 patients, who were confirmed as Moyamoya disease by cerebral angiography at Asan Medical Center. EEG and brain MRI were carried out in all subjects. RESULTS: 1) Epidemiologic data were : the male to female ratio was 1:1.1; highest rate(90.7%) of onset in age group below 10 years; mean age at clinical onset was 7.4 years; average diagnostic interval from clinical onset to diagnosis was 1.9 years. 2) The most common initial and recurrent or residual symptoms were motor deficit. 3) The most common site of occlusion or stenosis of cerebral vessel on cerebral angiography was anterior cerebral area(>97%) and the most common cerebral infarction area on brain MRI was anterior cerebral area, too. 4) The hyperventilation(for 3 minutes) on EEG were carried out in 25 patients and the prolonged build-up or rebuild-up phenomenon was observed in 13 patients(52%). 5) The prolonged build-up or rebuild-up phenomenon on EEG was observed in 6 of 15 patients who were occlusion of cerebral vessel, and in 7 of 10 patients who were stenosis of cerebral vessel on angiography. CONCLUSION: 1) The background slowings on EEG maybe suggestive of the infarction stage of Moyamoya disease in children. 2) The prolonged build-up or rebuild-up phenomenon might indicate the preinfarction stage of Moyamoya disease in children.

Delayed emergence of speech or language are frequent causes for concern about development during early childhood. Delay in evaluation and proper management until school entry in more likely to result in frustration, anxiety and school failure. Many language disturbances and their attendant behavior disorders respond to intensive language therapy. Authors analyzed the medical records of 52 children with delayed language development evaluated during 30 months from January 1986 through June 1988. The results were as follows: 1. The majority of cases were evaluated at the age of 2-2.9 year old (16 cases, 30.8%) and 3-3.9 year old (11 cases, 21.2%) 2. Male to female ratio was 3:1 3. The most common cause was mental retardation (53.8%), followed by developmental language disorder (23.1%) and autism (13.5%) 4. The most common associated condition was dysarticulation (17.3%), followed by strabismus (9.6%) and seizures (7.7%) 5. Special education was recommended in cases of 23 (44.2%), speech therapy in 12 cases (23.1%) and consultation to child psychiatry in 7 cases (13.5%) Making diagnosis of underlying disorders in not simple because assessment of intelligence in young children in difficult and only a few tests are standardized. More detailed study on children with delayed language development and development of psychometric tests for handicapped children are necessary, especially in Korea.

Hepatoid carcinoma is a rare type of malignant tumor resembling hepatocellular carcinoma that arises in extrahepatic sites.(stomach, lung, ovary, pancreas, bladder and renal pelvis). Hepatoid carcinoma of the ovary is an extremely rare ovarian tumor, first described by Ishikura and Scully in 1987. Histologically it is important to differentiate this entity from other oxyphil tumors of the ovary as it requires aggressive treatment. We have experienced a case of hepatoid carcinoma of the ovary in 69-year-old postmenopausal woman, who has been treated with operation and adjuvant Taxol - cisplatin chemotherapy. We present this case with brief review of literatures.

The changes of electroencephalogram(EEG) in patients with dementia are most commonly studied by analyzing power or magnitude in certain traditionally defined frequency bands. However because of the absence of on identified metric which quantifies the complex amount of information, there are many limitations in using such a linear method. According to chaos theory, irregular signals of EEG cal also result from low dimensional deterministic chaos. Chaotic nonlinear dynamics in the EEG can be studied by calculating the correlation dimension. The authors have analyzed EEG epochs from three patients with dementia of Alzheimer type and three matched control subject. The result showed that patients with dementia of Alzheimer type had significantly lower correlation dimension than non-demented controls on 12 channels. Topographic analysis showed that the correlation dimensions were significantly lower in patients with Alzheimer's disease on frontal, temporal, central, and occipital head regions. These results show that brains of patients with dementia with dementia of Alzheimer type have a decreased complexity of electrophysiological behavior. We conclude that the nonlinear analysis such as calculating correlation dimension can be a promising tool for detecting changes in the complexity of brain dynamics.

Angiogenesis depends on the net balance between positive and negative angiogenic factors. Tumor cells are angiogenic resulting from increased production of positive factors and decreased production of negative factors. Among these, vascular endothelial growth factor and glioma- derived angiogenesis inhibiting factor are related to glioblastoma multiforme. The p53 gene is more frequently mutated than any other known oncogene or tumor suppressor gene in human tumors including glioblastoma multiforme. Angiogenesis is reported to be controlled by p53 regulation in recent studies. To examine the effect of p53 overexpression on angiogenesis in glioblastoma multiforme, we performed immunohistochemical staining in 51 cases of glioblastoma multiforme, using monoclonal antibodies to p53 protein and factor VIII. 20 cases of low grade astrocytoma were used as control. p53 overexpression was present in 15(75%) of 20 cases of low grade astrocytoma and the mean vessel count was 37.7+/-9.9 at x200 field and 17.5+/-5.8 at x400 field. p53 overexpression was present in 35(68%) of 51 cases of glioblastoma multiforme and the mean vessel count was 91.9 45.8 at x200 field and 40.7 19.1 at x400 field. Mean vessel count in low grade astrocytoma with p53 overexpression was 39.4 10.2 at x200 field and 18.9 5.7 at x400 field, while in cases without p53 overexpression it was 32.4+/-7.6 at x200 field and 13.2 3.5 at x400 field. Mean vessel count in glioblastoma multiforme with p53 overexpression was 94.5+/-51.8 at x200 field and 42.1+/-16.8 at x400 field, while in cases without p53 overexpression it was 86.1+/-29.5 at x200 field and 37.1+/-16.8 at x400 field. The mean survival time was 12.4 months in the 39 cases of glioblastoma multiforme in which follow-up studies were possible. Significant prognostic factors were age, p53 overexpression and adjuvant therapy. These results show that p53 gene mutation is one of the many contributing factors to angiogenesis in glioblastoma multiforme. In addition, other oncogenes and tumor suppressor genes, as well as growth factors may be involved. Age, p53 overexpression and adjuvant therapy proved to be significant prognostic factors, while microvessel density was not.
