The influences of adrenal corticosteroid on the development and regression of neurons of dentate and hippocampus were studied by adrenalectomy and steroid overload in neonatal rats. The results obtained were as follows. 1. The cell death occurred naturally in numerous dentate granule cells and hippocampal pyramidal cells. 2. The number of dentate granule cells undergoing cell death decreased by injection of adrenal corticosteroid, but increased in adrenalectomized rat brains. The changes occurred prominently at postnatal day 6. 3. The number of hippocampal pyramidal cells undergoing cell death decreased in CA3 region by injection of adrenal corticosteroid, but was not changed in adrenalectomized rat brains. However, other regions exhibited no change by adrenal corticosteroid and adrenalectomy. 4. The cell death of pyramidal cells of CA3 region occurred in close relationship with the cell death of dentate granule cells, which was different from other CA regions. In summary, the cell death of dentate and hippocampal neurons occurred naturally but seemed to be influenced by other factors as well as adrenal corticosteroid.

The Dandy-Wlaker syndrome is a developmental disoeder characterized by cystic dilatation of the fourth ventricle and agenesis or hypoplasia of the cerebellar vermis and is usually associated with hydrocephalus. This syndrome is also associated with intracranial malformations such as agenesis of corpus callosum, and extracranial malformations such as facial anormalies (cleft palate, cleft lip, and ocular anomalies), polycystic kidney, and cardiac anormalies. Reported associated ophthalmic anomalies are microphthalmos, coloboma, and congenital cataract.We experienced a case of infantile esotropia in abnormal insertion and direction of lateral rectus muscle as a variant of the Dandy-Walker syndrome accompanied by cleft palate and cleft lip in a 19-month-old male infant. Subsequent treatment of the 30delta esodeviation and left inferior oblique muscle overaction, including resection of the lateral rectus muscle in both eyes and the myectomy of the inferior oblique muscle in the left eye, yielded satisfactory results, so we report this case, with a review of the pertinent literature, as the first case of Dandy-Walker syndrome associated with esotropia with abnormal course of lateral rectus muscle in Korea.

OBJECTIVE: The purpose of this study was to develop the decision tree models to classify the characteristics of those who had not undergone the health screening tests provided by the National Health Insurance Corporation. METHODS: Total of 5,102,761 subjects of health screening services in the year of 2002 was used. The data was divided into two data-sets (disease VS. non-disease group). The target variable was whether they took the health screening services. The number of input variables was 25 in total. RESULTS: The decision trees were classified into fourteen different types of non-examinees in the non-disease group and nineteen in the disease group. The ROC curve areas in the non-disease and disease groups were .761 and .714, respectively. CONCLUSION: The different types of non-examinees classified by the decision tree models would facilitate the foundation for the further analysis of individual characteristics and the effective health screening service management in future.

OBJECTIVE: To understand the clinical manifestations and disease course of adult onset Still' s disease (AOSD). METHODS: 15 patients of AOSD diagnosed at Severance hospital, Yonsei University College of Medicine were retrospectively analysed in the period of September 1988 to September 1995. RESULTS: There were 3 men and 12 women (male to female ratio of 1:4). Age of disease onset ranged from 17-55 years, and over 86% of the patients were younger than age 40 at disease onset. The prevalence of clinical features were as follows fever (100%), arthritis (93%), skin rash (93%), sore throat (60%), abnormal liver function (73%), lymphadenopathy (47%), splenomegaly (47%), hepatomegaly (20%), serositis (13%). Fever was the most common initial symptom. Common labaratory features were leukocytosis with neutrophilia (87%), anemia' Hgb <10 g/dL (67%), increased serum ferritin (83%), ESR (87%) and CRP (93%). Serum ferritin was markedly raised at disease onset and correlated with disease activity. In 2 patients, the disease was controlled with NSAID alone, but most of the patients required steroid to control the disease activity. In 6 patients, MTX was added for steroid sparing effect and for steroid resistant arthritis. Most of AOSD patients had intermittent and chronic disease course. Root joint arthritis and polyarthritis were factors associated with chronicity. CONCLUSION: The clinical features of AOSD in our study generally resemble previous reports. Serum ferritin was a useful marker of disease activity. Most patients of AOSD had intermittent and chronic disease course. Root joint athritis and polyarticular pattern at disease onset were factors associated with chronicity.

This study was carried out to compare the difference between assist(A) and controlled(C) ventilation group's blood gases during the general anesthesia. All samples were taken from the radial artery. The results were as follows, 1) Pa CO2was increased to 43. 9 5torr+/-7. 85 in group A and decreased to 28. 65 torr+/-6. 05 in group C. (p(0. 005) 2) Acidemia(7.335+/-0.51) in group A and alkalemia(7. 481+/-0.07) in group C were noticed. (p(0. 005) 3) B.E. and bicarbonate levels were within normal range in both groups. It's necessary to choose the patterns of ventilation before anesthesia, because of the anesthesiologist were apt to give alveolar hyperventilation during the controlled ventilation manually, but mild respiratory acidosis were developed during the assist ventilation.

Posterior reversible encephalopathy syndrome (PRES) is a transient condition characterized by altered mental status, seizure, headache, and visual disturbance with typical neuro-imaging findings in the bilateral parieto-occipital regions. Clinicians should be aware of this syndrome because delayed diagnosis and treatment result in irreversible neurologic deficits. We present the case of a 77-year-old male diagnosed with PRES in the setting of postoperative critical illness caused by small-bowel strangulation.

8.Effect of Clonidine for Suppression of Shivering after General Anesthesia.
Korean Journal of Anesthesiology 1995;28(5):708-712
We have studied the efficacy of intravenous clonidine to suppress postoperative shivering. Forty healthy patients who received general anesthesia and required treatment for shivering after operation were allocated randomly to two groups. Group 1 received normal saline 5 ml. Group 2 received 75 mcg intravenous clonidine. 2 minutes, 5 minutes and 10 minutes after treatment, the efficacy of treatment was recorded. Five minutes after treatment, 75 mcg clonidine obliterated shivering in 80% of patients. In contrast, none of the patients treated with normal saline had improved. Mean arterial pressure and heart rate were decreased significantly in patients given 75 mcg intravenous clonindine. But, none of them had required treatment for hypotension or bradycardia. We might say that 75 mcg intravenous clonidine is effective to suppress postoperative shivering without significant side effects.

9.Rapid Apolipoprotein E Genotyping by the Multiplex Amplification Refractory Mutation System.
Korean Journal of Clinical Pathology 2001;21(2):154-159
BACKGROUND: Currently, several different apolipoprotein E (apo E) genotyping methods have been developed. The Amplification Refractory Mutation System (ARMS) apo E genotyping, as previously described, requires four separate PCR reactions. The purpose of this study is to determine the clinical usefulness of the multiplex ARMS apo E genotyping with the use of only two PCR reactions. METHODS: We used five primers and two separate PCR reactions to detect the apo E polymorphism by using the multiplex ARMS technique. Apo E genotyping was performed with both the multiplex ARMS and INNO-LiPATM Apo E kit (INNOGENETICS) in 122 random samples. We investigated the effect of dimethyl sulfoxide (DMSO) in the multiplex ARMS PCR with various DMSO concentrations (0-15%). RESULTS: All six possible genotypes for apo E were clearly discernible with the multiplex ARMS. The apo E genotypes determined by the two methods were in complete agreement with all 122 samples. We found that DMSO is essential for the successful amplification of the multiplex ARMS and DMSO at concentrations of 3%-7% to be the optimal concentration. CONCLUSIONS: ARMS analysis involves two stages: PCR and agarose gel electrophoresis. Apo E genotyping using the multiplex ARMS requires only two PCR reactions. Thus, because of its simplicity, speed, accuracy, and cost-effectiveness, this method may be appropriate for determining the apo E genotypes in routine clinical laboratories.
