In order to assess the correlation of the myocardial damage and the duration of cardiopulmonary bypass, measurement of creatine kinase [CK], lactate dehydrogenase [LDH], asparatate aminotransferase [AST], and MB band of CK [CK-MB] were carried out on the first, third, fifth, seventh, and ninth day in 44 patients following open heart surgery [POD 1,3,5,7,9]. And the patients were divided into three groups according to the duration of aortic cross clamp time [ACT]: Group I [ACT< 60 minutes. n=19], Group II [60 minutes < ACT< 90 minutes, n=7] and Group III[90 minutes > ACT, n=18]. 1. The leakage of CK in total patients increased to the highest level at POD 1, with rapid decrease and recovery at POD 7. The leakage of CK in Group III were greater than in Group I from POD 1 to POD 3 [P < 0.01]. The recovery time of CK level was shorter in Group I [POD 3] than in Group II and III [POD 7]. 2. The serum levels of LDH in total patients increased to the highest level at POD 1, with slow recovery until POD 9. The levels of LDH in Group III were higher than in Group I until POD 9 [P < 0.005]. The levels of LDH in Group I and II recovered but not in Group III. 3. The serum levels of AST in total patients increased to the highest level at POD 1, with rapid decrease and recovery at POD 7. The levels of AST in Group III were greater than in Group I from POD 1 to POD 5 [P < 0.05]. The recovery time of AST level was shorter in Group I and II [POD 5] than in Group III [POD 7]. 4. The positive cases for CK-MB in 36 patients were 22 [61.1 %] as a whole, 5[41.6%] in Group I, 4[57.1 %] in Group II, 13[76.4 %] in Group III at POD 1, and a case in each group at POD 3, and only a case in Group Ill at POD 5. It is concluded that the myocardial injury was closely related with the duration of cardiopulmonary bypass in open heart surgery.

Purpose : Acute renal failure (ARF) is an important complication of rhabdomyolysis. The purpose of this study was to identify the major causes of rhabdomyolysis in children and to identify the factors associated with the developmet of ARF. Methods : A retrospective chart review between January 1997 to June 2005 was conducted of 60 patients with a diagnosis of rhabdomyolysis. Rhabdomyolysis was defined by an elevation of serum creatine phosphokinase (CK) greater than 1,000 IU/L with a MM fraction more than 95% or serum myoglobin>300 mg/dL or positive urine myoglobin. Patients were excluded if they had evidence of myocardial ischemia, or cerebrovascular insufficiency. Results : Sixty patients (37 males, 23 females) were enrolled, with the median age of 4.25 year. The most common causes of rhabdomyolysis were repiratory tract infection (9), seizure (7), hypoxia or asphyxia (6). Fifteen patients (25.0%) developed ARF and ten of them (66.0%) died. The initial serum creatinine, uric acid, potassium, pH and peak serum creatinine, initial systolic blood pressure, and mental status were statistically correlated with the development of ARF. The peak serum CK was associated with mortality of rhabdomyolysis. Conclusion : Acute renal failure was significant complication of rhabdomyolysis in children. Several clinical and laboratory factors were statistically associated with the development of ARF and death.

The effects of cheonggukjang (CK) on the weight gains, serum and hepatic lipids levels were investigated in adult female rats fed the cholesterol diets. Sprague-Dawley strain rats were given four different types of diet for 4 weeks, respectively: a normal diet, a control diet (10% fat + 0.5% cholesterol), a 5% or 10% CK diets (control diet + 5% or 10% CK powder). The body weights, food intake and food efficiency ratios, and the uterine fat pad weights of 5% CK and 10% CK groups were more significantly decreased than those of the control group. The liver cholesterol and triglyceride levels were significantly lower of the 10% CK group than those of the control group. The concentrations of serum triglyceride, total cholesterol, LDL+VLDL-cholesterol, and atherogenic index ratios were significantly decreased in the 10% CK group compared with those in the control group. The HDL-cholesterol/total-cholesterol ratios was significantly increased in the 10% CK group compared with those in the control group. The fecal total lipid excretion of the 5% and 10% CK groups were more increased than those in the control group. These results showed that the 10% cheonggukjang feeding decreased the triglyceride, total cholesterol, LDL+VLDL-cholesterol and atherogenic index ratios in serum as well as the triglyceride and cholesterol in liver, and increased the HDL-cholesterol/total-cholesterol ratio in serum.

Purpose: Elevated AST/ALT level in rotavirus gastroenteritis have been reported. We found elevated creatine kinase (CK) in those children. This study was carried out to define the relationship of major clinical presentation, laboratory findings, and level of creatine kinase. Methods: A retrospective analysis was made for thirty patients who were diagnosed rotavirus gastroenteritis from Jan 2001 to Mar 2005 in Department of Pediatrics, Gyeongsang National University Hospital. Serum creatine kinase was checked for the evaluation of high aminotransferase level among the patients. Results: Fourteen patients (8 males, 6 females) with high creatine kinase activity were included in this study. The mean age was $1.46{\pm}1.24year$ of age. The mean level of AST, ALT and CK were $127.5{\pm}136.2IU/L$, $126.1{\pm}154.3IU/L$, and $542.8{\pm}624.6IU/L$, respectively. Electrophoresis of CK isoenzyme was performed in four of them and the results revealed elevated CK-MM fraction (96~100%). Three of them revealed high serum creatine kinase acitivity (>1,000 IU/L) without acute renal failure and other symptom. However, none of them had muscular pain or trauma history. Elevated creatine kinase activity did not correlate with clinical implications (age, sex, vomiting, diarrhea, fever, symptom of URI, degree of dehydration or seizure) or laboratory findings. Conclusion: In this study, we found that serum creatine kinase acitivity also was elevated in infants with rotavirus gastroenteritis. This data support muscular damage due to rotavirus, but could not prove the mechanism of increased serum creatine kinase activity.

The purpose of this study was to isolate probiotic lactic acid bacteria (LAB) that produce bile salt hydrolase (BSH), and to evaluate its effects on serum cholesterol level. One-hundred-twenty bacterial colonies were initially isolated from human feces, and five strains were selected after screening based on their resistance to acids, tolerance against bile salts, and inhibitory activity on Escherichia coli. The Lactobacillus plantarum strain with the highest level of BSH activity was identified using 16S rRNA sequences, and was named L. plantarum CK 102. L. plantarum CK 102 at a level of 1.36$\times$10$^8$cfu/ml survived in pH 2 buffer for 6 h and exhibited excellent tolerance for bile salt. Coculturing the strain with E. coli in MRS broth resulted in strong inhibition against growth of E. coli at 18 h. Furthermore, the potential effect of CK 102 on serum cholesterol level was evaluated in rats. Thirty-two rats [Sprague-Dawley (SD) male, 129$\pm$l g, 5 weeks old] were divided into four groups of eight each. For six weeks, Group 1 was fed a normal diet (negative control); Group 2 was fed a cholesterol-enriched diet (positive control); Group 3 was fed a cholesterol-enriched diet plus L. plantarum CK 102 at 1.0$\times$10$^7$cfu/ml; and Group 4 was fed a cholesterol-enriched diet plus L. plantarum CK 102 at 5.0$\times$10$^7$cfu/ml. Blood samples were collected, serum lipids were analyzed, and weights of the organs were measured. Total blood cholesterol level, triglyceride, LDL-cholesterol, and free-cholesterol values were lower in rats that were fed 1. plantarum CK 102 than in those not fed L. plantarum CK 102. This cholesterol lowering effect implies that L. plantarum CK 102 could be utilized as an additive for health-assistance foods. In conclusion, these results suggest that the 1. plantarum CK 102 isolated could be used commercially as a probiotic.

The effects of cheonggukjang (traditional fermented soybean food, CK) and cheonggukjang added Phellinus linteus (CKP) on lipid metabolism were investigated in adult male rats. Twenty weeks old Sprague-Dawley rats were fed a purified hyperlipidemic diet (control diet: 0.5% cholesterol, 10% fat, 18% casein) for 4 weeks. The rats were randomly assigned to each treatment group control, two kinds of CK or CKP (powders of CK or CKP as dietary protein sources) After 5 weeks of CK or CKP diets consumption, the body weights, the hepatic and epididymal fat pad weights of the CK or CKP diets groups were significantly decreased than those of the control group. The liver cholesterol and triglyceride levels were significantly lower in both the CK and CKP diets groups than those in the control group. The concentrations in serum triglyceride, total cholesterol, LDL-cholesterol, and atherogenic index ratios were significantly decreased in the CK and CKP diets groups compared with those in the control group. The HDL-cholesterol/total-cholesterol ratios were significantly increased in the CK and CKP diets groups compared with those in the control group. Fecal cholesterol and triglyceride excretion of the CK and CKP diets groups were significantly increased than those of the control group. These results showed that both the feeding of cheonggukjang and cheonggukjang added Pheilinus linteus decreased the triglyceride, total cholesterol and LDL-cholesterol in serum as well as the triglyceride and cholesterol in liver, and increased the HDL-cholesterol/total-cholesterol ratio in serum of the rats.

Background : Monoclonal antibodies directed against well-known epitopes on cytokeratin (CK) 8, 18 and 19 (Monototal) have been used in the development of a new diagnostic tool for lung cancer. In the mid-1990s, CK 19 fragments (Cyfra 21-1) became popular and widely used for such diagnosis. This is the first study specifically designed to compare these two markers. Method : The serum levels of CK 8, 18 and 19 were measured using two-site monoclonal/polyclonal immunoradiometric assay kit in 57 healthy adults and 289 patients who were admitted to Seoul National University Hospital from May to September, 2002. The lung cancer group comprised 129 primary lung cancer patients; 116 with non-small cell lung cancer(NSCLC) and 13 with small cell lung cancer (SCLC). The control group comprised 160 non-malignant pulmonary lung disease patients and 57 healthy adults. A total of 166 twin Monototal and Cyfra 21-1 serum assays were obtained; 76 with lung cancer, 70 with non-malignant pulmonary lung disease and 20 healthy adults. Results : The mean serum value of Monototal was $412.47{\pm}455.45U/L$ in NSCLC, $237.08{\pm}145.15U/L$ in SCLC, $126.54{\pm}95.72U/L$ in non-malignant pulmonary lung disease, and $63.68{\pm}31.66U/L$ in healthy adults. The serum values of the lung cancer groups were significantly higher than those of the control group (p<0.01). Using a cut off value of 188U/L, sensitivity and specificity was 66.4% and 81.9% in NSCLC, and 43.8% and 81.9% in SCLC, respectively. The serum levels of CK 8, 18 and 19 were higher in advanced NSCLC than in early stage disease. Conclusion : The serum levels of CK 8, 18 and 19 may be useful in the diagnosis of NSCLC.

The effects of cheonggukjang(traditional fermented soybean food, CK) and cheonggukjang added Agaricus blazei (CKA) on lipid metabolism were investigated in female Sprague-Dawley rats (20 weeks old). The rats were fed a purified hyperlipidemic diet (control diet: 0.1% cholesterol, 10% fat, 18% casein) for 4 weeks. The rats were randomly assigned to each treatment group: control, two kinds of CK or CKA (powders of CK or CKA as dietary protein sources). After 8 weeks of experimental diets consumption, the body weights, and the uterine fat pad weights of CK and CKA diets groups were more significantly decreased than those of the control diet group. The liver cholesterol and triglyceride levels were significantly lower in both the CK and CKA diets groups than those in the control group. The concentrations in serum triglyceride, total cholesterol, LDL-cholesterol, and atherogenic index ratios were significantly decreased in the CK and CKA diets group s compared with those in the control group. The HDL-cholesterol/total-cholesterol ratios were significantly increased in the CK and CKA diets groups compared with those in the control group. The fecal cholesterol and triglyceride excretion in the CK and CKA diets groups were more increased than those in the control group. These results showed that both the feeding the rats with cheonggukjang and cheonggukjang added Agaricus blazei decreased the triglyceride, total cholesterol and LDL-cholesterol in serum as well as the triglyceride and cholesterol in liver, and increased the HDL-cholesterol/total-cholesterol ratio in serum.

In order to quantify compound K(CK), anticancer component of Panax ginseng C. A. Meyer, high titer rabbit polyclonal antibodies (pAbs) were raised against a conjugate of CK and bovine serum albumin coupled by a periodate oxidation method. Coating antigen (CK-OVA) was also prepared by the same method with OVA. As a result of optimization of antiserum dilution (2,000 fold), coating antigen ($25{\mu}g/ml$) and other condition (incubation time, temperature and washing method), ELISA method for the determination of CK was established. The measuring range extended from 0.5 ng/ml to 25 ng/ml of CK. The antibodies exhibited minor or even no cross reactivities with protopanaxatriol (1.56%) and other tested ginsenosides, $GRb_1$ (0.11%), $GRg_1$ (0.07%) except protopanaxadiol (87.2%) from the structural similarity. And the antibody showed good correlation (r=0.987) between the assay values obtained by this ELISA method and HPLC. Therefore, the ELISA method could be very useful tools for the determination of CK in biological fluids because of their high sensitivity and specificity.
