The purpose of this study was to investigate the prevalence and differences of risk factors of Metabolic syndrome according to menopausal status. From the database of the 5th Korea National Health and Nutrition Examination Survey (KNHANES V) conducted in 2012, data of 3,537 women who responded to health interview and health examination questionnaires. The presence of Metabolic syndrome was assessed using the International Diabetes Federation (IDF) criteria. The prevalence of Metabolic syndrome was 17.3% in premenopause and 54.3% in postmenopause. BMI, waist circumference, blood pressure, total cholesterol, LDL cholesterol, triglyceride, and Ferritin were higher in postmenopausal women compared to premenopausal women. However, postmenopausal women had lower HDL cholesterol and TIBC when compared to premenopausal women. Hypertension was the most prominent characteristic of postmenopausal women. Low HDL cholesterol showed up as a meaningful factor in premenopausal women. According to multiple regression analysis, waist circumference, fasting glucose, and HDL cholesterol were independent predictors of menopause. Therefore, obesity control and blood lipids management is recommended for postmenopausal women.

We measured the blood flow velocity of the anterior cerebral artery via anterior fontanelle approach of fifty five preterm neonates with duplex Doppler sonography and analyzed the waveform and calculated pulsatility index, resistive index. Intracranial velocities and pulsatility indexes were increased with increasing gestational age, birth weight, and age of the neonate, but resistive indices decreased. In sick babies, characteristic resistive index increment were seen in patients with intraventricular hemorrhage, but no statistical difference was seen in patients with respiratory distress syndrome. Our results suggest that duplex Doppler sonography is a useful noninvasive means of monitoring cerebrohemodynamics in normal preterm neonates and flow change of sick babies.

Baroreflex sensitivity (BRS) is a parameter of the cardiovascular system that is reflected in changes in pulse interval (PD and systolic blood pressure (SBP). BRS contains information about how the autonomic nervous system regulates hemodynamic homeostasis. Normally the beat-to-beat SBP measurement and the pulse interval measured from the electrocardiogram (ECG) are required to estimate the BRS. We investigated the possibility of measuring BRS in the absence of a beat-to-beat SBP measurement device. Pulse arrival time (PAT), defined as the time between the R-peak of the ECG and a single characteristic point on the pulse wave recorded from any arterial location was measured by photoplethysmography. By comparing the BRS obtained from conventional measurements with our method during controlled breathing, we confirmed again that PAT and SBP are closely correlated, with a correlation coefficient of -0.82 to -0.95. The coherence between SBP and PI at a respiration frequency of 0.07-0.12 Hz was similar to the coherence between PAT and PI. Although the ranges and units of measurement are different (ms/mmHg vs. ms/ms) for BRS measured conventionally and by our method, the correlation is very strong. Following further investigation under various conditions, BRS can be reliably estimated without the inconvenient and expensive beat-to-beat SBP measurement.

Antifreeze proteins and glycoproteins [AF(G)Ps] constitute a group of proteins that lower the freezing but not the melting points of aqueous solutions, enabling polar and north-temperate fish to survive in ice-laden environments. However, little is known about antifreeze activity in temperate fish; such work would extend our knowledge on the functions and evolution of AF(G)Ps. In the present study, we screened for antifreeze activity in temperate fish caught off the coast of Jumunjin ($37.89^{\circ}N$), Gangneung, Korea. Thermal hysteresis (TH) and the ability to inhibit ice recrystallization (IR) in blood, liver, and muscle samples from nine fish were examined to assess antifreeze activity. As the East Sea off the coast of Jumunjin is ice-free year round, we thought it most unlikely that the fish would express antifreeze proteins. Surprisingly, the blood of Pleurogrammus azonus and three types of tissue from Gymnocanthus herzensteini, Zoarces gilli and Kareius bicoloratus exhibited measurable TH values together with the ability to trigger characteristic morphological changes in ice crystals. Blood samples from the three species also evidenced ice recrystallization (IR) inhibition. This implies that AF(G)Ps or other antifreeze-like substances are present in temperate fish even under nonfreezing conditions. These results contribute to our understanding of the functions and origins of antifreeze activity in fish.

Both primary hepatoma and amebic liver abscess are probably the most common space-occupying disease of the liver in Korea, and the importance of their accurate distinction can not be overemphasized. Radiogold hepatoscanning has been widely used at St. Mary's Hospital, and recently blood disappearance rate of colloidal $^{198}Au$ has been introduced in the study of hepatic ailments. A review of the literature revealed few previous publications concerning the differential features of the two conditions although some characteristic scan findings of each condition have been described. The present study is aimed at a critical review and analysis of various photoscan findings and blood disappearance rate determinations of colloidal $^{198}Au$ of 34 cases of primary hepatoma and 30 cases of amebic liver abscess. Among many scan manifestations, prominence of the uninvolved liver tissue, "hemispherical cold area," and splenic uptake are much more commonly encountered in primary hepatoma and the blood disappearance rate tends to be far more frequently delayed in primary hepatoma than in abscess providing at least a statistically useful basis of distinction of the two diseases.

The rate of 58 neonatal calves in infection of Theileria sergenti was investigated in random samples on the farms located in Kyunggi, Chonbuk districts of Korea. 1. The criteria used in veryfying infection with T. sergenti included the detection of parasites by giemsa stain and acridine orange stain in the blood smear slides. 2. Further evidence of current or previous exposure to T. sergenti was based on demonstration of T. sergenti specific antibody and antigen by the western immunoblot and the directed immunofluorescent antibody test in the peripherial blood of the calves. 3. The prevalence rates were 35%, 50% in Kyunggi, Chonbuk provinces respectively and the overall prevalence in all the farms was 43.2％ by means of acridine orange stain. 4. The parasites that were observed in the peripherial blood of calves was showen surely by the western immunoblot to the characteristic 34KD antigen among the proteins of T. sergenti (Korean isolate). 5. And the antigen of the neonatal calves reacted at the very highest titer(1 : 2, 560) 6. These data highlight the significances of T. sergenti in the neonatal calf disease in Korea.

DW2282,(S)-(+)-4-phenyl-1-[1-(4-aminobenzoyl)-indoline-5-sulfonyl]-4,5-dihydro-2-imidazolone hydrochloride, is a new anticancer agent which is thought to exhibit a characteristic mechanism of action in the inhibition of tumor growth. In this study, we estimated the toxicities of DW2282 in mice. When mice were orally dosed for five consecutive days at the dosages of 50, 100 and 150 mg/kg, DW2282 did not induced methemoglobinemia and hypoglycemia at any of these doses. However, increased ALT and AST values were observed in the 150 mg/kg dosing group, and white blood cells (WBC) were significantly decreased at all doses. However, the changes in WBC count, ALT and AST immediately reversed after the cessation of drug administration. In addition, we found that DW2282 did not cause an increase in hemolysis in human blood. Taken together, these data suggested that DW2282 may have a relatively low level of toxicity, and that there may be a quick recovery from any toxicity it dose produce.

Purpose : This Study was conducted to evaluate clinical characteristic of children with recurrent abdominal pain (RAP) and to be classified by its six subtype in the Oriental Pediatric Text Book and to find out relationship of western classification. Methods : Patients who visited Dong-Eui Oriental Medical hospital from August, 2001 to October, 2002 due to RAP were included. According to questionnaire and history taking, RAP was classified by its six subtype based on Oriental medical theory. Results : 1. Patients with RAP were more internalized, have a close relation with their parents, and have strong desires of success, but social intercourse is low. 2. 76% of Patients have a less desire to eat and 67% of Patients have a diarrhea or constipation. 3. According to questionnaire, first abdominal pain was their $3{\sim}5$ ages most, cause of occurrence was more 'eating cold foods' most, time of AP (abdominal pain) was $1{\sim}2$ hours after eating and no characteristic most, site of AP was the umbilicus most, shape of AP was impotent pain most, cause of reduce pain was abdominal massage and defection most. 4. frequency of RAP's type, AP caused by diet(食積腹痛) is 45.5%, AP caused by cold(寒腹痛) is 29.1%, AP caused by cold in internal organs of deficiency(臟腑虛冷腹痛) is 12.7%, stagnation of qi and stasis of blood(氣滯血瘀腹痛) is 10.9%, AP caused by internal diet and external cold(內食外寒腹痛) is 1.8%. There is no AP caused by parasites(蟲腹痛). 5. During clinical classifications of RAP, cause of occurrence was most important cause of reduce pian, defection practice was helpful for diagnosis, but shape of AP, site of AP was not helpful. 6. With relationship of Oriental classification and western classification, AP caused by diet is similar to dysmotilitylike dyspepsia and irriTable bowel syndrome. AP caused by cold is similar to irriTable bowel syndrome. AP caused by cold in internal organs of deficiency is similar to unspecified dyspepsia. stagnation of qi and stasis of blood and AP caused by internal diet and external cold is not like to western classification. Conclusion : RAP in Childhood is most occurred by food and cold. there is few AP caused by stagnation of qi and stasis of blood and internal diet and external cold. So the study on subclassification and clinical Manifestations of RAP in Childhood is more performed.

This study was carried out to find out some characteristic responses of biological samples under the exposure of trace metals with the considering of Sex, age, residence period and smoking. Blood, Urine and Hair were collected from 116 dwellers in the vicinity of a smelting factory. Cd, Cu, Pb and Zn concentrations were determined by flame atomic absorption spectrophotometry and the following results were found important. 1) The concentrations of trace metals in the blood were 0.010+ 0.003 $\mu$g/ml in Cd, 0.82+ 0.11 $\mu$g/ml in Cu, 0.23_+ 0.13 $\mu$g/ml in Pb and 5.78_+ 1.43 $\mu$g/ml in Zn, those in the urine were 1.7_+ 1.7 $\mu$g/l in Cd, 16.5_+ 16.0 $\mu$g/l in Cu, 24.6_+ 23.0 $\mu$g/l in Pb and 367.7_+ 283.4 $\mu$g/l in Zn, and those in the hair were 0.52_+ 0.56 $\mu$g/g in Cd, 11.00_+4.01 $\mu$g/g in Cu, 8.53_+ 7.05 $\mu$g/g in Pb and 383.23_+ 110.56 $\mu$g/g in Zn. 2) In sex, the concentrations of Zn in the blood and urine of male were higher than those of female, however, the concentrations of Cd and Zn in the hair of female were higher than those of male. 3) The concentrations of Cd, Pb and Zn in the urine showed an increasing trend by age. 4) While the concentration of Cd in the urine increased, the concentration of Pb in the hair decreased by residential period in all the samples. 5) The concentrations of Cd and Zn in the blood and that of Zn in the urine of smoking group were higher than those of non-smoking group. The concentration of Pb in the blood of smoking group and those of Cd, Pb and Zn in the urine of non-smoking group showed increasing the trend by age. The concentrations of Cd and Zn in the urine of non-smoking group, the concentration of Zn in the hair of smoking group showed increasing trend by residential period, however, the concentrations of Pb in the blood and hair and that of Zn in the hair showed decreasing trend by residential period. 6) When the correlations of the concentrations between Zn (main smelting metal) and other metals were analyzed, Zn in the blood was significantly correlated with Cu, Pb and Zn in the urine (positively) and Zn in the urine was significantly correlated with Zn in the blood, Cd, Cu and Pb in the urine, and Pb in the hair (positively). Zn in the hair was significantly correlated with Cd in the urine and Cu in the hair (positively). 7) Consequently, it was useful to note that samples of urine showed higher sensitivity under the metal exposure than those of blood and hair in individual sampling. In addition, as trace metals showed higher accumulation in the hair of the groups, sampling of hair was more highly recommended than those of urine and blood in group sampling.
