This study was to provide basic data for aquatic ecosystem research using fishes. Field sampling was carried out at five selected sites of Gap Stream, and fish samples, especially for a selection of sentinel species were collected three times in June, September, and October 2007. We analyzed total length distribution of Zacco platypus in relation with the season and the sampling sites, and then compared with total body weight, condition factor (K), and age distribution of the fish. The fish population data were compared with physico-chemical water quality, obtained from the Ministry of Environment, Korea. Water quality analysis showed a significant nutrient enrichment, based on total nitrogen (TN) and total phosphorus (TP), and organic matter pollution, based on biological oxygen demand (BOD) and chemical oxygen demand (COD) in the Site 5, which is directly influenced by wastewater disposal plant (WDP). Population analysis of the sentinel species showed that the total number of individuals, age distribution, and the population size-structure were influenced by the effluents from the WDP, and that reproductive failure of young-age population were evident in Site 5. According to the relation analysis of total weight to K, the disturbed population was mainly attributed to combined effects of habitat modifications and chemical degradations. Regression analysis of K values against water quality parameters showed significant (p<0.05) positive relations with nutrient and organic matter contents. Our data suggest that the population structure using a sentinel fish species reflected the ambient water quality in the stream and that diagnosis of aquatic ecosystem health using Z. platypus population may be practical for water resource and ecosystem conservations.

Coronary artery calcification(CAC) is found frequently in the atheromatous plaques. CAC is known to have increased frequency above 40 years. CAC without evidence of atherosclerosis in young adults is quite rare, however, CAC combined with aneurysms in young adults have been infrequently reported in patients with a past history of a Kawasaki disease in child. We report an autopsy case showing CAC and aneurysm in the absence of macroscopically identified atherosclerotic lesions in a healthy 23-year-old man. The autopsy examination revealed aneurysmal dilatation of the right coronary artery, which was connected with calcified lesion. A calcified lesion of the left anterior descending coronary artery was aslo noted. Microscopically, aneurysmal wall was non-specific except for hyalinized wall and foci of calcification. A striking histologic finding of calcified mass was ring calcification along the wall of the coronary artery. Antecedent Kawasaki disease in the past was suggestive as other reports.

Laparoendoscopic single-site surgery (LESS) is helpful if not an evidence of suspicious malignancy in huge adnexa tumors. This approach might be reasonable alternative to conventional laparoscopic surgery. We report two cases with LESS for huge cystic adnexal tumors in whole abdomen. A 58 years old multigravida woman in menopause underwent removal of a huge cystic adnexal mass that occupied her entire abdomen by LESS.(ca.5200ml aspiration) A 15 years old single nulligravida woman had a huge cystic adnexal tumor in whole abdomen reaching to the level of the xyphoid process. A needle through the transumbilical single port was inserted directly under the mass. Subsequently, 8000 ml of cystic fluid was aspirated without spillage.

As medical technology progresses rapidly, there is a rise in the average age along with the Korean dietary lifestyle becoming more westernized, which leads to an increase in the number of vascular disease patients in Korea. Thus, we need to manage the medical information of a disease systematically in order to diagnose and treat constructively. However, since there has been no standardized method of man agement to date, a great deal of information could not be properly utilized nor studied. Therefore, the departments of Cardiology, Radiology and Neurology of Samsung Seoul Hospital recently got together to develop an information management system called the Vascular Data System. This program was developed to be run on win98 O/S, upper Pentium Ⅲ, and upper 128 MB Memory, and its source code is Dephi 4.0. It was configured for the user to set the configurations as well as do a variety of search and analysis. If this program were to be updated continuously, it may be used extensively as well as in various parts of clinical research activities.

Optic neuritis presents differently in children than in adults. Children typically have bilateral involvement with papillitis following an antecedent viral illness. The development of multiple sclerosis is less common in children. The diagnosis of optic neuritis is usually made on a clinical manifestations. The major symptoms of optic neuritis include one or more of the following: 1) sudden blurred, "foggy" vision and sudden loss of vision, 2) pain with eye movement in the affected eye, 3) sudden color blindness, and etc. This condition progresses over a few days to two weeks. A 12-year-old girl presented with a history of sudden visual loss and color blindness. Treatment with high doses of steroid resulted in visual function returning to normal.

Acute intermittent porphyria is a disorder that results from partial porphobilinogen deaminase deficiency and accumulation of overproducted porphyrin and its precusors. This makes variable manifestations such as abdominal pain, nausea, vomiting, contipation, peripheral neuropathy, seizure, psychotic symtoms, respiratory failure, tachycardia, and hypertension. When acute paroxysmal hypertension presents, it is difficult to differentiate from pheochromocytoma. We experienced a case of young female with acute intermittent porphyria presenting paroxysmal recurrent headache, palpitation, chest discomfort and paroxysmal hypertension. Initially blood pressure was 160/100 mmHg and checked high paroxysmally on follow up. Rhythm was sinus tachycardia. She did not complain any other specific symptoms. Although her clinical manifestations were suspicious for pheochromocytoma, laboratory findings were not compatible to it. In searching other causes of secondary hypertension mimickng ph대chromocytoma, elevated urine porphobilinogen level was detected and we could make diagnosis of acute intermittent porphyria. If AIP was not beared in mind as a cause of secondary hypertension, diagnosis would be delayed more.

Background : Coronary disease is highly prevalent in patient with end stage renal disease (ESRD) and account for much of their observed morbidity and mortality. Troponin-I consistently maintains a high sensitivity and specificity and is most sensitive marker for ischemic heart disease (IHD). Method : We examed 49 hernodialyzed patients (22 male, 27 female) without evidence of acute coronary syndrome (ACS) for 6 months. Biochemical markers were measured in serial predialysis blood samples. For analysis, we used two cardio-specific assays for troponin-T (cTnT) as well as for troponin-I (cTnI) and compared the results with CK-MB (reference value ≤ 4.0 ng/mL) concentration. Results : Myocardial ischemia was observed in 47% (23/49) of patients. cTnT level above 0.1 ng/mL. and cTnI level above 0.5 ng/mL, were observed in 22% (11/49) and 20% (10/49) of patients respectively. cTnI revealed significantly higher positive rate in patients with myocardial ischemia than the patients without myocardial ischemia (43 % vs 30%) (p<0.05). cTnT and CK-MB revealed no difference in positive rate between the patients with and without myocardial ischemia (cTnT : 30% vs 15% and CK-MB : 30% vs 19%). The sensitivity and specificity of cTnI to myocardial ischemia were higher than those of cTnT and CK-MB (sensitivity 43% vs 30% and 30%. specificity 100% vs 85% and 81%). Conclusion: Both cTnT and cTnI are useful in ruling out myocardial injury in chronic renal failure patients. But. cTnI is a more sensitivity and excellent specificity of ischemic heart disease than cTnT and CK-MB in hemodialyzed patients. In patients with ischemic heart disease, the presences of DM and advanced age were higher than those in patients without ischemic heart disease (p<0.05). Among the baseline characteristics old age, elevated LDH and diabeties were significant more frequent in the patients with elevation of cardiac troponin-I (p>0.5 ng/mL) than those with cardiac troponin-I (p<0.5 ng/mL), p=0.038, p=0.049, and p=0.045, respectively. Our results suggest that these cTnI is the potential diagnostic marker for the prediction of IHD in ESRD patients.

The waxy rice flours were prepared from Sinsunchalbyeo and Hwasunchalbyeo using dry-pin and wet-roller mill, and the properties were investigated. Proximate composition and physicochemical properties of waxy rice flours were similar between two varities, but were different between milling methods. Water binding capacities, soluble carbohydrates and damage starch contents of waxy rice flours were similar between two varities, but were higher in waxy rice flour using wet-roller milling method than using dry-pin milling method. The crystallinities by X-ray diffractorgrams were all A-type. By Scanning Electron Microscope, waxy rice flours were shown large granule surrounded with film like material and the granules were attached with starch granules. The film like material was more tightly bound with granules in flours by dry-pin milling method. Peak viscosity of wet-roller milled flours by Rapid Visco Analyzer(RVA) was higher than that of dry-pin milled ones, but initial gelatinization temperatures were lower in flours by wet-roller milling method.
