  • Purpose: With increasing prevalence of hypertension (HTN) in children and adolescent, pediatricians have become more interested in blood pressure (BP) measurements. The ambulatory blood pressure monitoring (ABPM) is known to be useful to differentiate true HTN and white coat HTN. The object of this study is to assess the clinical usefulness of ABPM in Korean children and adolescents. Methods: A retrospective review of 51 patients in Kyungpook National University Hospital from January 2002 to February 2010 was done. All patients were 6-18 years old and underwent ABPM. We calculated the mean value of ABP, BP load, nocturnal dip and compared the results with the patients' diagnosis and characteristics. Results: The mean age of the 51 patients was $17.8{\pm}1.8$ years and 19 children were obese. 37 patients (72.5%) were truly hypertensive and 1 patient was diagnosed as masked HTN and 7 children (14%) as white coat HTN. The rest of the patients were normotensive. Among patients with white coat HTN, 5 were in a prehypertensive state. Mean systolic and diastolic BP load of patients with true HTN were significantly higher than non-hypertensive children (P<0.001). Although the nocturnal dip of all patients were below 10%, there was no statistical significance. The obese patients showed higher systolic and diastolic BP. Their systolic and diastolic BP load were significantly higher than non-obese patients (P<0.001). Conclusion: ABPM in children and adolescents seems to be a valuable tool in the assessment of white coat HTN and in the confirmation of true HTN. A considerable number of white coat HTN patients are revealed to be in a prehypertensive state and need close follow-up.

  • These studies were conducted to compare the nutritive values and optimum prices of eggs among 6 groups of different egg Weight. With the total of 100 eggs of each weight group, after the weight percentage of egg yolk, albumen and shell in the whole egg were investigated, protein and fat contents of e99 yolk and albumen were analyzed. and then protein and fat contents in the whole eggs were calculated. Finally, the optimum prices of eggs in relation to the egg weight were studied on the basis of egg weight, protein content and protein plus fat contents of eggs, respectively. The results obtained are summarized as follows; 1. As the egg weight (X, g/10 eggs) increased, egg yolk (Y$_1$, %) and shell(Y$_2$, %) percentages tended to decrease, but egg albumen(Y$_3$, %) percentage increased lineally; Y$_1$=44.34-0.02X, Y$_2$=15.358-0.006 X, and Y$_3$=40.136+0.026 X. 2. There were no significant differences in protein and fat contents of eggs among 6 different groups of egg weight. 3. Protein (Y$_1$, %), fat (Y$_2$, %) and protein plus fat (Y$_3$, %) contents in the whole eggs declined progressively as the egg weight (X, g/10 eggs) increased ; Y$_1$=11.943-0.00032X, Y$_2$=13.996-0.00614X, and Y$_3$=25.939-0.00646X. 4. Similar results were obtained whether the optimum prices of eggs were estimated on the basis of egg weight or protein content of eggs, and they were higher in the large size eggs and lower in the small size eggs than the optimum prices of eggs estimated on the basis of protein plus fat content of eggs.

  • Examining the polychaetous annelids collected from the Yellow $Sea(30^{\circ}20'\;N\;Lat.\;124^{\circ}35'\;E\;Long)$ Jinhae Bay, Yeocheon Bay, Jeju Do and Weolpo. I found five species which should be added in the list as new to the polychaetous annelids fauna of Korea. In the present study five species are reported morphological descriptions. Consquently, a total 125 species of polychaetous has been reported(Kamita and Sato 1941; Paik 1972, 1973a, 1973b, 1975a, 1975b, 1976, 1977, 1978, 1979; Lee 1976; Rho and Song 1974, 1975) in Korea.

  • The author presents the history of introduction of biofeedback system into Korea, depending on his personal experience at the Seoul National University Hospital. He, as the witness of biofeedback applied to clinical psychiatry and research in Korea, maintains that biofeedback should receive much more attention filled with enthusiasm, particularly because of the rapid development of medical engineering backed up by the unimaginable progress of computer- and neuro-science.

  • The chemical constituents of Selaginella tamariscina were studied. From the n-hexane, chloroform and n-butanol soluble fractions, three compounds were isolated by chromatographic purification process. They were identified as lutein, $3{\beta}-cholesterol$ and hinokiflavone by spectral anaylsis(IR, MS, UV, $^1H-NMR$, $^{13}C-NMR$ and DEPT). Lutein and $3{\beta}-cholesterol$ were first isolated compounds from Selaginellaceae and hinokiflavone was a reported compound from this plant.

  • Six monoclonal antibodies to human cardiac troponin I (hcTnI) were produced to eventually develop an immunosensor for acute myocardial infarction (AMI). For the characterization of these antibodies, a set of 11 different peptides covering selected ranges of the complete amino acid sequence of hcTnI was prepared and used for epitope mapping. Such analysis allowed to select an appropriate pair of antibodies that can form a sandwich type of immune complexes and was consequently used for an immunoassay.

  • From the chloroform and n-butanol extracts of Selaginella tamariscina, three biflavonoids were isolated by chromatographic separation. Structures of these compounds were determined as cryptomerin B, amentoflavone and isocryptomerin by spectroscopic analysis, and amentoflavone was further identified by comparison with the authentic sample. This is the first report of isolation of cryptomerin B from Selaginellaceae.
