Objective:There have been a kind of transmethylation theory that high homocysteine serum concentration affects schizophrenia by neurotoxic mechanism and clinical reports that some schizophrenic patients with high homocysteine were improved by high folate ingestion. This study was done to confirm previous research results and find the clinical characteristics of schizophrenia showing high serum homocysteine and low folate. Method:We compared the serum levels of homocysteine, folate and vitamin B12 level between 234 schizophrenic patients(male 99, female 135) group and 234 normal controls(male 99, female 135) group. The subjects of two groups were age and sex matched. The evaluated clinical characteristics items were sex, age, onset of disease, hereditary loading, disease course, hallucination and subtype of schizophrenia. Results:1) Homocysteine level of the schizophrenia group was significantly higher than the normal control group and folate level of the schizophrenia group was significantly lower than the normal control group. Homocysteine level was more negatively correlated with folate level in the schizophrenia group than the normal control group. 2) The percentage of high homocysteine(above 12.46umol/L;90 percentile of normal control) was 33.8% of schizophrenia patients and 51.5% of male schizophrenia. The percentage of low folate(below 3.8nM/L;bottom tertile of normal control) was 66.2% of schizophrenia. 3) In low folate group and not-low folate group, schizophrenia showed significantly higher homocysteine level than normal control. Especially, low folate schizophrenia group showed significantly higher homocysteine level than low folate normal control group. Conclusions:Some schizophrenia patients with high serum homocysteine may be genetic defector and having low folate serum level. In that case, folate ingestion could be a good management for clinical improvement.

Objectives : The aim of this study was to examine if there is a significant correlation between the changes of Fire- and Heat- related symptoms and motor function recovery in acute cerebral infarction patients. Methods : We studied inpatients within a month after the onset of cerebral infarction who were admitted at Kyunghee University Medical Center from May 2011 to January 2013. We executed correlation analysis between Fire-heat pattern score and motricity index score at visit 1 and visit 2, and checked if there was a significant correlation between the changes of Fire-heat pattern score and changes of motricity index score. Also, we compared the changes of both scores in patients taking Fire-heat and non Fire-heat pattern prescriptions. Results : There was a significant correlation between the Fire-heat pattern score and Motricity index score at visit 1 and visit 2, and changes of Fire-heat pattern score showed significant correlation with changes of motricity index score. Patients taking Fire-heat pattern prescriptions showed significant change in Fire-heat pattern score after herb-medication treatment while patients taking non-Fire-heat prescriptions showed insignificant change in Fire-heat pattern score. Conclusions : This study provides evidence that taking a Fire-heat pattern prescription could be considered as a first line herb-medication treatment in acute cerebral infarction patients.

Purpose: This study was conducted to analyze the clinical manifestation and natural course of benign transient hyperphosphatasemia (BTH) in children. Methods: A total of 17 children diagnosed with BTH between June 2006 and July 2007, were included in this study. Clinical records and laboratory tests were analyzed retrospectively for all children. Results: The mean age of the patients was $26.9{\pm}13.8$ months (range: 9 to 49 months). Nine of the 17 BTH cases (52.9%) occurred in patients that had previously suffered from infectious diseases. While the patients were suffering from BTH, the mean serum level of alkaline phosphatase (ALP) was $2,500.2{\pm}1,165.1$ U/L, however, these elevated serum ALP levels normalized within 7 weeks of recovery in all cases. In addition, a seasonal peak in the onset of BTH was observed from September to December. Further, the measurement of ALP isoenzymes in 7 of the patients with BTH, revealed a marked elevation of bone fraction. Conclusion: It is important for pediatricians to understand the clinical manifestation and benign course of BTH to avoid unnecessary diagnostic evaluation in children showing a transient increase in ALP activities.

The influence of the storage temperature at $15^{\circ}C$ on the biochemical and structural changes in the red muscles (M. sternomandibularis) of korean native cattle postmortem were studied. The results obtained were summarized as follows; 1.5 to 2 hours postmortem the pH-value had dropped to $6.7{\sim}6.8$, after 18 or 20 hours at $15^{\circ}C$ it had reached its final pH-value (5.5). The irreversible loss of extensibility, i.e. the onset of rigor mortis, arose at $15^{\circ}C$ between 9 and 10 hours postmortem at pH 6.1 to 6.0 and R-value between 1.05/1.10. The complete loss of extensibility postmortem was reached after 18 to 20 hours at pH 5.5/5.6. Muscle and sarcomere length of korean native cattle were contracted about 20% and 15%, respectively at $15^{\circ}C$. Meat of korean native cattle had the highest shear force (4.7 kg) on 1 day after slaughter. The tenderness was increased with the ripening period prolonged and was highest at the end of the 9 day ripening period.

This study was done to examine the prognosis according to onset and duration of treatment in acute ischemic cerebral infarction patients. We analysed NIHSS(National Institutes of Health Stroke Scale) score of acute ischemic cerebral infarction patients who visited department of Internal Korean Medicine, one medical center in Busan from January to December 2009. We divided patients into two groups by the initial time of treatment. Group A is admitted within 7 days, Group B is admitted from 7 to 14 days. We used NIHSS for functional recovery after 3 weeks later from admission day, and analyzed prognostic factor by analysis of covariance. All patients showed statistically significant improvement after 1week, 2weeks, 3weeks from admission, and between 1st week and 2nd week. However, there was no significant difference between 2nd week and 3rd week. NIHSS recovery score after 3weeks were analysed according to the timing of treatment. There was a statistically significant difference between two groups. The percentage of aggravated patients showed no statistically significant difference between the two groups. This study suggests that earlier admission care has an effect on functional recovery of patients with acute ischemic cerebral infarction. Further research on the large scale and long-term follow up is required.

To elucidate the mechanism of age-related development in FGS/NgaKIST mice with spontaneous glomerulosclerotic lesion, we examined expression and localization of various cytokine mRNA in the kidney in the progression of diseases. This mouse model is the first to develop spontanously occuring glomerosclerotic lesion in the kidney. In this study, we detected the up-regulation of local cytokine genes such as IL-1$\beta$, IL-2, IL-6, IL-10, TNF-$\alpha$, TGF-$\beta$, and IFN- $\gamma$ in the kidneys. In RT-PCR and Southern blot analysis, we detected gradual expressions of cytokine mRNA of IL-1$\beta$, IL-2, IL-6, IFN- $\gamma$, and TNF $\alpha$ mRNA during the course of disease. Other cytokines including IL -10 and TGF -$\beta$ were found to be appeared the slightly expressed level at 3 to 12 weeks before onset of inflammatory lesion but they are highly expressed at the end-stage of the disease accompaning high proteinurea and wasting. In situ RT-PCR, each cytokine mRNA were specifically localized in a variety of cells including mesangial, endothelial, parietal epithelial, tubular epithelial, arterial muscle cell, and infiltrated inflammatory cells. In addition, TNF - $\alpha$was detected moderately in the visceral and parietal epithelial cell, but weakly in endothelial and mesangial cells, whereas IL-1 $\beta$ and IL -6 were strong in mesangial regions. IL-6 and TNF- $\alpha$ was highly localized in the damaged proximal and collecting tubules. Especially, TGF -$\beta$ mRNA was highly found in mesangial cells within glomerulus and interstitium during the end-stage of this disease.. These results indicate that pro inflammatory cytokines such as IL-1 $\beta$, IL-2, IL-6, and TNF- $\alpha$ were gradually expressed from the early stage of this disease to the end-stage, and that IL-10 and TGF-$\beta$ may be important in the accumulation of extracellular matrix(ECM) within glomerulus and periglomerular fibrosis in the progression of this disease as well as tissue destruction in end-stage of this disease.

The physicochemical properties of tuber starch in water chestnut have been studied. Peak viscosity, hot paste viscosity and cooling peak viscosity were 5679, 3146 and 4262 RVU, respectively. In three transition parameters, onset temperature ($T_o$), peak temperature ($T_p$), and conclusion temperature ($T_c$) were 64.1, 68.5 and $72.3^{\circ}C$, respectively. Gelatinization enthalpy (${\Delta}H$ gel) was 4.48 J/g. A-type starch has a smaller proportion (11.4%) of short chains ($DP{\geq}12$) and a larger proportion (57.2%) of short chains ($13{\leq}DP{\geq}24$). The tuber starch of water chestnut displayed an A-type X-ray diffraction pattern showing a strong diffraction peak at $2{\Theta}$ values of $15.18^{\circ}$, $17.13^{\circ}$, and $23.1^{\circ}$, and a weak peak at $2{\Theta}$ values of $18.1^{\circ}$, $20.06^{\circ}$, and $26.69^{\circ}$. Their crystallinity was 28.6% and the mean starch granule size was 21.5 ${\mu}m$.

The lungs are frequently the site of adverse drug reactions because of their higher oxygen concentration, the distinctive properties of the pulmonary circulation, and the close proximity of the alveolar epithelium to the blood. Amiodarone, an iodinated benzofuran derivative, is an effective antiarrhythmic drug commonly used for refractory tachyarrhythmia. However, it has a wide range of adverse effects, the most serious of which is lung disease. Most patients present with the insidious onset of dyspnea and a nonproductive cough, and generally recover after withdrawing the drug. We recently experienced four fatal cases of amiodarone pulmonary toxicity. Therefore, we discuss these unusual drug-induced pulmonary toxicity cases with a review of the relevant literature.

Lennox-Gastaut syndrome (LGS) is one of the most severe epileptic encephalopathies of childhood onset. It is characterized by multiple types of generalized seizures, slowness of intellectual growth, and specific electroencephalogram pattern. It is one of the most difficult epilepsy syndromes to treat and is frequently resistant to treatment. In this case report, we report a case of dental treatment under general anesthesia in a child with LGS. A 4-year-6-month old boy with LGS visited Seoul National University Dental Hospital for dental treatment. Dental treatment was planned under general anesthesia because of his medical condition. Treatment was successfully done without any postoperative complications. If a LGS patient requires dental treatment, a treatment plan should be established to take into account the degree of seizure, the medication being used, and the cooperation of the patient. If the degree of seizure is severe and the patient's cooperation is poor, dental treatment under general anesthesia would be advantageous.

To investigate the effort of drying methods on the physicochemical properties of agar, gel strength, viscosity, melting and setting point, and phase transition by differential scanning calorimetery (DSC) during its heating were determined. In addition the structural differences of agar powder by scanning electron microscope (SEM) was examined. The most shortest onset temperature of gel strength increase was extruding method among any other methods. Viscosity of agar with hot air method, 400.00 cps at $45^{\circ}C$, was markedly increased, but with spraying and extruding ones were little change. The melting and setting point, and the temperature for maximum endothermic and enthalpy for agar with extruding one, $80.01^{\circ}C,\;36.05^{\circ}C\;and\;61.72^{\circ}C,\;0.73\;cal/g$, respectively, were lowest among the drying ones. But in the case of reheating after gelling, there were little change in all methods. Observing the surface structure of agar with SEM, extruding method showed the most unstable with absorptive property.
