The distribution of exogenous C(14)-succinic acid by Clonorchis sinensis incubated in Tyrode medium was studied by using autoradiographic techniques. A comparison was made between macro and microautoradiographs of this worm showed that black grains derived from labeled substance were distinctly observed in parenchymal tissue, oral sucker, ventral sucker, ovary, testes, and uterine tubules with eggs. In pharynx and intestine, a low density was monitored while negligible activity was found in seminal receptacle and vitelline follicles. In studying the further details, microautoradiography was utilized. The most radioactive regions were the reticular tissue and subcuticular musculature of this fluke, closely compatible with the finding of macroautoradiography. Apparent black grains of radioactivity were also found in oral sucker, ventral sucker, pharynx, uterine tubules, eggs in uterus, and intestinal ceca. Structures showing the least radioactivity included ovary, seminal receptacle and vitelline folliciles.

Nonconvulsive status epilepticus, which constitutes about 25% of all cases of status, has been subdivided into generalized nonconvulsive(absence) status and complex partial status. We report a case of complex partial status epilepticus in a 3-year-old male patient with altered mental function lasting about 24 hours. The electroencephalographic finding was compatible with complex partial status and the outcome of treatment is excellent, so far.

Segmental vitiligo is considered to be characterized by unilateral depigmented patches along dermatomes, but we found two cases of segmental vitiligo in which the vitiligo lesions appeared bilaterally on the same or different dermatomes. The clinical course of bilateral segmental vitiligo seems to be the same as that of unilateral segmental vitiligo.

OBJECTIVE: Estrogen is a major regulator/modulator of bone metabolism, and bone loss in estrogen deficiency is associated with increased bone turnover, But the mechanism for estrogen action on bone metabolism is still unknown. Recent studies have suggested that the increase in bone loss induced by estrogen deficiency is mediated by increased paracrine production of bone resorbing cytokines. Among cytokines, 1nterleukin-6(IL-6) is released from osteoblasts in estrogen deficiency and increases bone resorption by stimulation of osteoclastic activities and recruitment. Thus we performed this study to evaluate the effect of ovariectomies on bone mineral density and IL-6 in cultured monocytes of peripheral blood and bone marrow. METHODS: The experimental animals were 13 female Sprague-Dawley rats that were 8 weeks of age and weighed an average of 188.5 gram at the beginning of the study. Bilateral ovariectomies were performed in all rats from a ventral approach. Bone mineral density(BMD) of the total body, spine and level of IL-6 of cultured monocytes of peripheral blood and bone marrow were measured before and 8 weeks after ovariectomy. RESULTS: 1) BMD of total body and spine were lower after ovariectomy(0.257+/-0.069g/cm2, 0,208+/-0.005g/cm2) than before ovariectomy (0.276+/-0.005g/cm2, 0.229+/-0.011g/cm2), respectively (P<0.01). 2) Although IL-6 level of cultured monocytes in peripheral blood tended to be higher after ovariectomy than before ovariectomy, this difference was not statistically significant (P>0.05). 3) IL-6 level of cultured monocytes in bone marrow was higher after ovariectomy(82.78+/-4.99pg/ml) than before ovariectomy(48.85+/-2.42pg/ml)(P<0.05). CONCLUSION: It is possible that increased production of IL-6 in estrogen deficiency induced by ovariectomy occurs in the local environment of bone or bone marrow rather than in the pheripheral blood and stimulates bone resorption.

BACKGROUND: Vascular dementia is common cause of dementia, second to the dementia of Alzheimer desease. However in Asia and many developing countries, the incidence of vascular dementia exceeds that of Alzheimer's disease. Though many stroke-related factors related the nature of vascular injury, e.g. infarction and hemorrhage, have not assessed yet. Clarifying the difference of electroencephalograpy and clinical prognosis between infarction and hemorrhage, the aim of this study was to elucidate the role of nature of vascular injury. METHODS: to reduce confounding factors, the study population was restricted to the patients of single hemispheric striatocapsular infarction and hemorrhage saving cortex. On admission, we checked the KMMSE and FIM scores and using quantified EEG, we analyzed occipital peak frequency and the relative background alpha, theta and delta spectra power taken from 16 derivations by averaging twenty-2 -sec epoch in infarction, hemorrhage patients and elderly controls. After 6 months follow up, we compare the MMSE, FIM score between infarction and hemorrhage group. RESULTS: 1) Compared with infarction group, hemorrhage groups had a significantly bilateral lower occipital peak freqauency and background bilateral alpha spectra power. 2) In hemorrhage group, there is lower tendency in K-MMSE after 6 month follow up compared to infarction group. CONCLUSION: This study suggests that hemorrhage show more bilateral electrophysiological dysfunction than infarction group and possible grave prognosis for vascular dementia compared to infarction group.

Ectopic thymus results from the aberrant migration of thymic tissue and is mostly present in the mediastinum, the base of the skull, the tracheal bifurcation and the cervical region. We report the first case of intraabdominal heterotopic thymus incidentally detected and attached to the liver without associated anomalies. This fetus was sent to the Department without any clinical information. The fetus was small for gestational age, but had no external abnormalities. Each organ showed normal development except for the liver. The liver weighed 6 gm(normal 17.064+/-4.143 gm). Gray white heterotopic thymus was attached to the superior surface of the liver in the subdiaphragmatic area. It measured 1.1x0.6x0.5 cm. There was no diaphragmatic defect. The cervical thymic tissue near the thyroid was small and measured 0.2 gm(normal 0.927+/-0.485 gm). There was no thymic tissue in the anterior superior mediastinum. The histologic features of the heterotopic thymus were identical to the orthotopic thymus showing features appropriate for the gestational age. The origin of this subdiaphragmatic heterotopic thymus is speculated.

A case of pulsating exophthalmos is reported in a 50 years old Korean Woman. The complaints of this case were exophthalmos, chemosis on Rt. eye and intracranial bruit. The etiology of this case is considered due to toxemia of pregnancy and hypertension without trauma. A brief review of the literatures related with the etiology, symptom and therapy is made.

Ependymomas constitute no more than 5 to 7% of all primary CNS neoplasm and their biologic behavior is difficult to predict by microscopic appearances. Recently, many studies have attempted to correlate biologic behavior with tumor proliferation index, tumor suppressor gene and oncogene using immunohistochemical stains. We evaluated 25 cases of surgically resected intracranial ependymomas for the proliferation activity using Ki-67, and expression of p53 and bcl-2 protein with regard to the prognosis. The cases were divided into 17 ependymomas (WHO Grade II), 3 papillary ependymomas (WHO Grade II), and 5 anaplastic ependymomas. Clinically, the patients were divided into two groups, recurrent (18 cases) or non-recurrent (7 cases). The Ki-67 proliferation index was significantly higher in the recurrent group (p<0.05) and in the younger ages (correlation index=0.534). Although Ki-67 proliferation index was higher in anaplastic ependymoma, it was not significant statistically (p>0.05). p53 protein expression tended to increase in the patients who had anaplastic ependymoma and in the recurrent group. bcl-2 expression was not correlated with histologic grade or recurrence of the tumor. We conclude that Ki-67 proliferation index and p53 expression are important markers for predicting biologic behavior of ependymoma.

BACKGROUND: To comparatively analysis the epidemiological changes in the acute drug intoxication between 1980s and 1990s. METHODS: We reviewed retrospectively the medical records of the patients with acute drug intoxication in the emergency department of the Inha hospital from June 1986 to April 1987 and from June 1996 to May 1997. And we performed comparative analysis between two result. RESULTS: The ratio of the acute drug intoxication in the emergency medical center was reduced significantly in 1990s against 1980s. Sexual ratio and prevalent age group has no significant interval changes between 1980s and 1990s. The prevalent seasons were Spring in 1980s and Summer in 1990s but has no significance. The most commonly used drugs was rodentides in 1980s and hypnosedatives in 1990s and shown significant interval changes. The most common motive was suicidal attempts in both 1980s and 1990s, but significantly reduced. After emergency treatment the rate of curative-discharge has improved and the rate of admission has decreased significantly in 1990s against 1980s. The most critical agent was agricultural chemicals in both 1980s and 1990s. The mortality rate has no significant interval changes. CONCLUSION: There were some significant interval changes of the acute drug intoxication in prevalence rate, commonly used drugs, ratio of suicidal attempt and curative-discharge rate between 1980s and 1990s. New education programs far preventing acute drug intoxication and strict legal control of drugs are important and necessary.
