Byoung-won Park,Seong Soon Kwon,Min Ho Lee,Do Hoi Kim,Min Su Hyon,Duk Won Bang 순천향대학교 순천향의학연구소 2018 Journal of Soonchunhyang Medical Science Vol.24 No.1
Objective: Contrast-induced nephropathy (CIN) frequently occurs after percutaneous intervention. Objective of this study was to investigate the usefulness of serum cystatin C, neutrophil gelatinase-associated lipocalcin (NGAL), urinary kidney injury molecule-1 (KIM-1), and interleukin-18 (IL-18) as early predictors for CIN after percutaneous coronary intervention (PCI). Methods: In 53 patients who underwent PCI were enrolled. Serum creatinine and cystatin C level were measured immediately before, and 24 hours and 48 hours after catheterization. Serum NGAL, urinary KIM-1, and IL-18 were measured immediately before, and 4 hours, 24 hours, and 48 hours after catheterization. CIN was defined as a rise in creatinine 0.5 mg/dL or 25% above baseline. Results: CIN occurred in four patients (7.5%). Serum cystatin C levels were higher at 24 hours and 48 hours in CIN patients than in those without CIN (P<0.05). Serum NGAL levels were higher at 48 hours in CIN patients than in those without CIN. Urinary KIM-1 levels were higher at 48 hours in CIN patients than in those without CIN. There were no significant markers of CIN on multi-variate analysis. Conclusion: In this study, the occurrence of CIN after PCI was 7.5%. Although there were some time-course changes in serum cystatin C and urinary KIM-1 after PCI, there was no significant predictor for CIN after PCI.

Vitellogenin(Vtg), a phospholipoglycoprotein precursor of egg yolk, is synthesized and secreted from the liver in response to estrogens in female fish. Vtg is normally undetectable in the blood of male fish, but can be induced by exposure to chemicals possessing estrogenic activity. Thus, the presence of Vtg in blood of male fish can serve as a useful biomarker for assessing previous exposure to estrogenic compounds. In the present study, Vtg was abnormally expressed in Rhynchocypris oxycephalus treatment of Estradiol Benzoate (E_(2)). As the result, it was found that the level of Vtg in blood from R. oxycephalus was increased by treated quantity of E_(2) with dose-effect manner.

The purpose of this study was to investigate the relationship between the micro-structure and hardness of Ni-Cr alloy(Talladium™ alloy) and Co-Cr alloy(Wironium^(?) extra-hard alloy), which are widely used as partial denture frame work these days, depending on the cooling method, followed by casting. The frist group was bench cooled at room temperature(20℃), the second group was slowly cooled in the furnace from 700t to room temperature, and third, rapidly cooled in 20~22℃ water. The micro-structures of each specimen were compared by means of photomicrograph taken by metallurgical microscope. In addition to the physical characteristics of each specimen were obtained using the Rockwell C Scale. The results were obtained as follows: 1) The hardness value of Talladium™ alloy appeared higher than the Wironium^(?) alloy. 2) The hardness value of the slow cooling method(in the furnace) appeared higher the than the bench cooling method, water cooling method. 3) The grain particle in the slowly cooled alloy were much finer than the bench cooling method, water cooling method. 4) In the cooling method of Talladium™ alloy and Wironium^(?) alloy for partial denture the slow cooling method was considered more profitable than the bench cooling method, water cooling method.

The hardness of four kinds of cr-co alloys and one kind of Titanium alloy, which are widely used as partial denture framework these days, were measured and the following result were obtained. The tested alloys of cr-co alloy are Vitallium alloy (AUSTENNAL Co., U.S.A), and Biosil alloy (DEGUSSA Co., GERMANY), and Wironium extra-hard alloy (BEGO Co., GERMANY), and Ticonium alloy (TICONIUM Co., U.S.A), and Titanium alloy are pure titanium. (OHARA Co., JAPAN). 1. The cr-co alloy showed higher value (331.46±2.73Hv-376.74±2.34Hv) (RHN-30N : about 53.72-57.88) than the pure titanium alloy one (211.76 ± 11.2Hv) (RHN-30N value : about 36.66). 2. The hardness value (376.74+2.34Hv) (RHN-30N : 57.88) of experimental Ⅱ alloy was the highest. 3. The hardness value (211.76±11.2Hv) (RHN-30N : 36.66) of experimental Ⅴ alloy was the lowest. 4. These results suggested that the method of bench cooling was more effective.

Objectives : The aim of study is to compare the neuropsychological function changes between day hospital schizophrenic patients and out patient schizophrenic patients and to examine the effect of day hospital program on the cognitive function of schizophrenics. Methods : Neuropsychological test was done two times at discharge and 2 months later in 11 day hospital schizophrenic patients and 10 out patient schizophrenic patients by DSM-Ⅳ criteria. Vigilance, motor performance series are used as a computerized neuropsychological batteries. Results : Day hospital patients have significantly increased performance in some of motor performance series test items, but sustained attention have no tendency for increasing in day hospital patients. Conclusion : This results are preliminary. But this study suggest that psychomotor function of schizophrenics can be changed following day hospital treatment. And also we suggest that further day hospital treatment program expecially including congnitive rehabilitation needed.

In this paper, a fuzzy logic controller is designed for speed control of a hydraulic inverter elevator. Mathematical modeling of an elevator actuated with hydraulic system is presented and the friction characteristics of a cylinder is examined, which may cause the abrupt increase of the acceleration in the zero-crossing speed region. Simulation results show that the proposed fuzzy logic speed controller yields a better control performance than conventional PID controller.

Polycythemia vera is one of the myeloproliferative diseases, and as such, is an example of clonal hematopoiesis. The progeny of a single, abnormal, hematopoietic stem cell gain a grwoth advantage over their normal counterparts resulting in overproduction of red cells generally accompanied by overproduction of granulocytes and platelets as well. There are a variety of nonspecific symptoms at onset related to the increased red cell mass and hematocrit accompanied by the more specific manifestations of pruhtis, erythromelalgia, and hepatic, portal, and mesenteric vein thrombosis. Splenomegaly and hypertension are common. Thrombosis and leukemia are frequent complication in polycythemia vera and are associated with severa organ damage and a high mortality. We report here the case of occurrence of myocardial and cerebral infarction in a patient with polycythemia vera.
