BACKGROUND/OBJECTIVES: College students are in a period of transition from adolescence to adulthood, in which proper dietary habits and balanced nutritional intake are very important. However, improper dietary habits and lifestyles can bring several health problems. This study was performed to investigate blood lipid profiles, blood aluminum and mercury in college students and the relationships among them. SUBJECTS/METHODS: The subjects were 80 college students (43 males and 37 females) in Gyeonggi-do. General characteristics, anthropometric measurements, blood pressure, blood lipids, SGOT, SGPT, and blood aluminum and mercury of the subjects were measured and analyzed, and their relationship was studied. RESULTS: The BMI was significantly higher in males, $23.69{\pm}3.20kg/m^2$, than in females, $20.38{\pm}2.37kg/m^2$ (P < 0.001). The blood pressure was significantly higher in males with $128.93{\pm}12.92mmHg$ systolic pressure and $77.14{\pm}10.31mmHg$ diastolic pressure compared to females with $109.78{\pm}11.97mmHg$ and $65.95{\pm}6.92mmHg$, respectively (P < 0.001). HDL cholesterol in males, $61.88{\pm}13.06mg/dl$, was lower than $64.73{\pm}12.16mg/dl$ in females, but other blood lipid levels were higher in males. Blood aluminum was significantly higher in males, $9.12{\pm}2.11{\mu}g/L$, than in females, $8.03{\pm}2.14{\mu}g/L$ (P < 0.05), and blood mercury was higher in males, $3.08{\pm}1.55{\mu}g/L$, than in females, $2.64{\pm}1.49{\mu}g/L$. The blood lipids showed positive correlation with obesity and blood pressure. CONCLUSIONS: The degree of obesity, blood pressure, triglycerides, and LDL cholesterol were higher in males, suggesting possible association with chronic disease incidence such as hyperlipidemia and hypertension. Thus, it is considered that a systematic health education is needed for college students, especially for males.

In this study, two experiments were conducted to evaluate the total mixed ration with fermented feed (TMRF) and total mixed ration (TMR) by rumen in vitro fermentation and their effects on the growth performance and blood characteristics of Hanwoo steers. In experiment 1, three Hanwoo steers ($600{\pm}47$ kg), each permanently fitted with a ruminal cannula were used. In this experiment, three diets designated as T1, TMRF (18.4% fermented feed, tall fescue, mammoth wild rye forage and whole crop barley); T2, TMRF (17.7% fermented feed, rice straw and whole crop barley); and T3, TMR (rice straw, whole crop barley and probiotics, but no fermented feed), which were subjected to rumen in vitro fermentation for 48 h. The results demonstrated that DM disappearance rate gradually increased with advancing fermentation time, but T1 and T2 were higher than the T3 (p<0.05) from 3 h to 12 h, but insignificant (p>0.05) at 24 and 48 h. None of the specific VFAs were affected except for acetic and non volatile lactic acids, which were produced more in T2 than in T1 and T3 at 24 h and 48 h of incubation. A/P was lower in T1 and T2 than inT3 at 24 h (p<0.05) and 48 h (p>0.05) of incubation. These results confirmed that TMRF-related treatment shows a superior performance to that of TMR during the ruminal fermentation period. In experiment 2, the three diets in experiment 1 plus 1 more control diet (concentrates, probiotics and 2% rice straw of body weight) were fed to the 48 Hanwoo steers ($160{\pm}10$ kg) for a period of 168 d. The results demonstrated that the daily and total live weight gain and feed efficiency were higher (p<0.05) in the TMRF and TMR groups than in the control group. SGOT, SGPT and BUN (p<0.05) were reduced in TMRF relative to the control and TMR groups by 168 d which confirmed that TMRF shows better blood profiles than the TMR and control groups. Overall, these results appear to show that TMRF has better in vitro ruminal characteristics than those of TMR; growth performance and blood profiles were also found to be superior in TMRF than in the TMR and control groups. Thus, our findings suggest that TMRF-based feed supplies are favorable for Hanwoo cattle.

This study was initiated to investigate the effects of organic germanium on cadmium and mercury intoxication. The effect was determined by the metallothionein induction in liver and kidney. Male rats (Sprague-Dawley) were treated with CdCI$_{2}$ (2mg/kg), HgCI$_{2}$ (1 mg/kg) and organic germanium (GE-132) (100 mg/kg) in single and in combination via intraperitoneal injection or intragastric administration every other days for 17 days. Experimental animals were sacrificed after 7, 12 and 17 days treatment. The serum transaminase activities (SGOT, SGPT), concentration of metal and metallothionein, metal-binding capacity of metallothionein in liver and kidney were determined and pathomorphological observations were undertaken. The combined treatment of GE-132 and CdCI$_{2}$ significantly decreased the increment of serum transaminase activities in rats treated with CdCI$_{2}$ only, but the combined treatment of GE-132 and HgCI$_{2}$ did not affect to activities of transaminases induced by mercury only. The concentration of metals (Cd and Hg) except Ge in the liver and kidney of rats increased with the time of treatment. Mercury concentration in kidney of rat treated with HgCI$_{2}$ only was significantly higher than the combined treatment of GE-132 and HgCI$_{2}$. The combined treatment of GE-132 and CdCI$_{2}$ significantly increased the concentration of metallothionein in liver compared to the CdCI$_{2}$ only, although the concentration of cadmium in liver were not significantly different between two groups. This indicates that GE-132 decreased toxicity of cadmium in liver by promoting metallothionein induction. There were no significant differences in metallothionein concentration in liver and kidney of rats between the combined treatment of GE-132 and HgCI$_{2}$ and HgCI$_{2}$ only. Metal-binding capacity of metallothionein varied with each time intervals in liver and kidney of metals treated rats except the liver of the combined treatment of GE-132 and CdCI$_{2}$. This finding explains the concentration of metallothionein in liver keeps abreast with the concention of metal. Furthermore, the combined treatment of GE-132and CdCl$_{2}$ revealed pathologically less changes in liver tissue than CdCl$_{2}$ only; the damages of liver cell, such as lobular necrosis and portal inflammation, were relieved and appeared more later. From the above results, organic germanium is considered to have some beneficial effect on the protection of liver from the cadmium intoxication.

We investigated the rate of hepatitis G virus infection among 50 patients who were not infected with the hepatitis C virus but showed symptoms of hepatitis. Viral RNA was extracted from the patients' sera and cDNA was synthesized and amplified by RT-PCR (reverse transcription-polymerase chain reaction) using random hexamer and 5 primers (470-20-1-77F, 470-20-1-211R, 470-20-1-211R-biotin, GV57-4512MF, GV57-4657MR). The amplified PCR products were confirmed by electrochemiluminescence (ECL), liquid hybridization (LH) and Southern blotting (SB). Among the 50 PCR products, by means of ECL, we found 4 samples to be positive and 5 samples to be indeterminate. The GV45-89M probe (5'-CYCGCTGRTITGGGGTGTACfGGAAGGC-3') was end-labelled with gamma-$^{32}P$ ATP and used for liquid hybridization with the PCR products. By using liquid hybridization, we detected specific bands from 4 positive sera and also from one indeterminate serum as determined by ECL. An 1.5% agarose gel electrophoresis of the 9 PCR products which were HGV positive or indeterminate as determined by ECL showed a 160bp band from 4 positive and one indeterminate serum. The 5 PCR products proved to be positive when SB was applied with the GV45-89M probe as well as when LH was applied. LH and SB were shown to have higher sensitivity and specificity than ECL. Two cases among 5 positive cases had relatively high SGOT, SGPT, ALP values when compared with other 48 cases. In summary, we confirmed hepatitis G virus infection in 5 cases among 50 Korean patients showing symptoms of viral hepatitis.

Objective: This study was to assess liver involvement in multiple myeloma with the aid of liver function tests. Materials and Methods: A hospital based retrospective study was undertaken using data retrieved of multiple myeloma from the register maintained in the Department of Biochemistry of the Manipal Teaching Hospital, Pokhara, Nepal between $1^{st}$ January, 2007 and $28^{th}$ February, 2012. We collected biomarkers of liver profiles including bilirubin (Total, Direct and Indirect), total protein, albumin, AG ratio, SGOT, SGPT, ALP, ${\gamma}GT$, LDH, ferritin, renal profile and hematological profile. Descriptive statistics and testing of hypothesis were used for the analysis using EPI INFO and SPSS 16 software. Results: Out of 37 cases of multiple myeloma, serum level of AST, ALT, ALP, ${\gamma}GT$ and LDH were increased above the cut-off point in 22 (59.5%), 24 (64.86%), 13 (35.13%), 9 (24.3%) and 11 (29.7%) respectively. The mean values of AST ($65.5{\pm}28.18$ U/L), ALT ($68.37{\pm}29.74$ U/L), ALP ($328.0{\pm}148.4$ U/L), ${\gamma}GT$ ($44.5{\pm}29.6$ U/L) and LDH ($361.7{\pm}116.5$ U/L), total protein ($9.79{\pm}1.03$ gm/dl) were significantly increased when compared with controls. In contrast, albumin ($3.68{\pm}0.43$ gm/dl) and the AG ratio ($0.62{\pm}0.15$) were significantly decreased. Similarly, anemia, hyperuricemia, azotemia, hypercalcaemia and Bence Jones proteinuria were found in 30 (78.9%), 27 (71.1%), 19 (51.5%), 15 (39.5%) and 16 (42.1%) respectively, in cases of multiple myeloma. Conclusions: While clinical manifestation of liver disease among the multiple myeloma was not common, abnormalities in liver function were characteristic.

This study was conducted to investigate the effect of a 3 week low calorie diet (LCD) and a 9 week of behavior modification (BM) program on the weight loss, mineral and vitamin status in 22 obese women. The subject were healthy, obese (PIBW> $120\%$) women aged 20 - 50 Yr and not taking any medications known to influence body composition, mineral or vitamin metabolism During the LCD program, subjects were provided commercial liquid formulas with 125 kcal per pack and were instructed to have a formula for replacement of one meal and at least one regular meal per day within the range of daily 800 - 1200 kcal intake. During the BM program the subjects weekly attended the group nutrition counseling session to encourage themselves to modify their eating behavior and spontaneously restrict their energy intakes. The BM program focused on stimulus control, control of portion sizes and modification of binge eating and other adverse habits. The initial mean energy intake of subjects was 2016.9 $\pm$ 129.8 kcal ($100.8\%$ of RDA) and dropped to 1276.5 $\pm$ 435.7 kcal at the end of a 3 week of LCD program and elevated to 1762 $\pm$ 329.3 kcal at the end of a 9 week of BM program. Carbohydrate, protein and fat intakes were significantly decreased at the end of the LCD but carbohydrate was the only macro nutrient that showed significant decrease (p < 0.05) at the end of the BM program compared to baseline. Calcium and iron intakes decreased significantly (p < 0.01, respectively) with no significant changes in other micronutrients at the end of the LCD. The mean weight of the subjects decreased from 73.8 $\pm$ 8.0 kg to 69.2 $\pm$ 7.7 kg with LCD and ended up with 67.7 $\pm$ 7.1 kg after 9 weeks of BM. The 3 weeks of LCD reduced most of the anthropometric indices such as BMI, PIBW, fat weight, wast-to-hip ratio and subscapular and suprailiac skinfold thickness. The 9 weeks of behavior modification showed slight change or maintenance of each anthropometric measurements. Weight loss and decreased WHR with the diet program induced significantly decreased systolic blood pressure. SGOT, SGPT and serum insulin levels with improved serum lipid profiles. Biochemical parameters related to iron status such as hemoglobin, hematocrit were significantly decreased (p < 0.01) at the end of the LCD. But their mean values were within normal range. The mean serum 25 (OH) vitamin $D_3$ level significantly increased after whole diet program. Serum folate level significantly decreased after 12 weeks of diet program. In conclusion 3 weeks of LCD brought 4.6 kg reduction in body weight without risk of iron, zinc or vitamin D deficiency and 9 weeks of the BM was effective to maintain nutritional status with slightly more weight reduction (1.5 kg). However calcium intake and serum folate should be monitored during the LCD and BM because of increased risk of deficiencies.

Cardioplegia and myocardial protection were performed under cardiopulmonary bypass during open heart surgery with the use of St. Thomas Hospital cardioplegic solution [4 [C] for the coronary artery perfusion and normal saline solution [4[ c] for the topical cardiac cooling. To maintain the state of myocardial protection, coronary artery reperfusion was carried out using St. Thomas Hospital cardioplegic solution at the interval of 30 minutes. A total number of patients studied were 57 cases, including 37 cases of correction for congenital anomalies and 20 cases for acquired heart diseases. Cardiopulmonary bypass time during the surgery was observed to be average of 87.89*47.55 hours, aortic cross-clamping time [ACCT] to be average of 76.68*44.27 hours raging from 30 to 191 minutes. In order to evaluate the effects of myocardial protection in the surgery, serum enzyme levels were determined. To observe the relationship between ACCT and myocardial protection effects, patients studied were divided into the following 3 groups. I group: ACCT 60 minutes, II group: ACCT 90 minutes, III group: ACCT over 91 minutes [1] SGOT; The positive value [increased over 200 units] for ischemic myocardial injury during operation was observed in 11 cases [19.3% of the total] of the total patients studied, of which 4 cases [13.3%] in I group, 1 case [10.0%] in II group, and 6 cases [35.3%] in III group. [2] LDH; The positive value [increased over 900 units] for ischemic myocardial injury during operation was observed in 9 cases [15.7% of the total] of the total patients studied, of which 2 cases [6.6%] in I group, 1 case [10.0%] in II group and 6 cases [35.3%] in III group. [3] CPK; The positive value [increased over 800 units] for ischemic myocardial injury during operation was observed in 10 cases [17.5% of the total] of the total patients studied, including 4 cases [13.3%] in I group, 1 case [10.0%] in II group, and 5 cases [29.4%] in III group [4] The myocardial protection method used in the present study was demonstrated to be effective for the myocardial protection in the surgery with ACCT of up to 90 minutes. A few ischemic myocardial injury were observed in the surgery with ACCT over 91 minutes, but no significant cardiac dysfunction was noted. The surgery with ACCT of up to 191 minutes did not appear to give rise any significant interference with postoperative recovery.

We have studies in 38 subjects (19 control and 19 experiment) for development of functional food for postpartum body control. Mean age of control and experimental subjects were each other 30.4 and 29.0 years old, and mean body mass index were 20.2 and 21.4. Total weight gain during pregnancy of control and experimental subjects were 14.0kg and 19.8kg. We measured change of weight and liver activity after parturition for 3 months. It shows that weight not reduced until 30 days in postpartum but significantly decreased during 30 days to 90 days. The mean weight of control and experimental subjects were decreased 3.15kg and 6.46kg at 60 days(p<0.05), 4.47kg and 7.44kg at 90 days(p<0.05). In this study, hemoglobin, GOT and CPT level were not changes before and after of experiment, respectively.

Mechanical obstruction of the common hepatic duct includes the following causes ; choledocholithiasis, sclerosis, cholangitis, pancreatic carcinoma, cholangiocarcinoma, postoperative stricture, primary hepatic duct carcinoma, enlarged cystic duct lymph nodes, and metastatic nodal involvement of the porta hepatis. Partial mechanical obstruction of the common hepatic duct caused by impaction of stones and inflammation surrounding the vicinity of the neck of the gallbladder had been reported on the "syndrome del conducto hepatico" in 1948 by Mirizzi. Nowadays, this disease was named by Mirizzi syndrome. Mirizzi syndrome is a rare entity of common hepatic duct obstruction that results from an inflammatory response secondary to a gallstone impacted in the cystic duct or neck of the gallbladder. It results from an almost parallel course and low insertion of the cystic duct into the common hepatic duct. In a varient of Mirizzi's syndrome, the cause of the common hepatic duct obstruction was a primary cystic duct carcinoma rather than gallstone disease. A 71-year-old man was admitted with a four-day history of right upper quadrant abdominal pain. Past medical history was unremarkable. On physical examination, the patient had a temperature of $38^{\circ}C$, icteric sclera and right upper quadrant tenderness. Pertinent laboratory findings included WBC 18,000/$cm^2$;albumin 2.6g/dl(normal 3.9-5.1) ; SGOT 183u/L(normal 0-50) ; SGPT167u/L(normal 0-65) ; bilirubin, 8.2mg/dl(normal 0-1) with the direct bilirubin, 4.4mg/dl(normal 0-0.4). Ultrasonography revealed a dilated extrahepatic biliary tree. ERCP showed that the superior margin was angular and more consistent with a calculus causing partial CHD obstruction(Mirizzi syndrome). At surgery a diseased gallbladder containing calculi was found. In addition, there was two calculi partially eroding through the proximal portion of the cystic duct and compressing the common hepatic duct. A cholecystectomy and excision of common bile duct was performed, with Roux-en-Y hepaticojejunostomy. The postoperative course was uneventful.

Since the iron balance is maintained by regulated intestinal absorption rather than regulated excretion, there have been many reports concerning the factors which may influence the intestinal iron absorption. As the liver is the largest iron storage organ of the body, any hepatocellular damage may result in disturbances in iron metabolism, e,g., frequent co-existence of hemochromatosis and liver cirrhosis, or elevated serum iron level and increased iron absorption rate in patients with infectious hepatitis or cirrhosis. In one effort to demonstrate the influence of hepatocellular damage on intestinal iron absortion, the iron absorption rate was measured in the rabbits whose livers were injured by a single subcutaneous injection of carbon tetrachloride (doses ranging from 0.15 to 0.5cc per kg of body weight) or by a single irradiation of 2,000 to 16,000 rads with $^{60}Co$ on the liver locally. A single oral dose of $1{\mu}Ci\;of\;^{59}Fe$-citrate with 0.5mg of ferrous citrate was fed in the fasting state, 24 hours after hepatic damage had been induced, without any reducing or chelating agents, and stool was collected for one week thereafter. Serum iron levels, together with conventional liver function tests, were measured at 24, 48, 72, 120 and 168 hours after liver damage had been induced. All animals were sacrificed upon the completing of the one week's test period and tissue specimens were prepared for H-E and Gomori's iron stain. Following are the results. 1. Normal iron absorption rate of the rabbit was $41.72{\pm}3.61%$ when 0.5mg of iron was given in the fasting state, as measured by subtracting the amount recovered in stool collected for 7 days from the amount given. The test period of 7 days is adequate, for only 1% of the iron given was excreted thereafter. 2. The intestinal iron absorption rate and serum iron level were significantly increased when the animal was poisoned by a single subcutaneous injection of 0.15cc. per kg. of body weight of carbon tetrachloride or more, or the liver was irradiated with a single dose of 12,000 rads or more. The results of liver function tests which were done simultaneously remained within normal limit except SGOT and SGPT which were somewhat increased. 3. In each case, there has been good correlation between the extent of liver cell damage and degree of increased iron absorption rate or serum iron level. 4. The method of liver damage appeared to make no obvious difference in the pattern of iron deposit in liver. This may be partly due to the fact that tissue specimens were obtained too late, for by this time the elevated serum iron level had returned within normal range and the pathological changes were almost healed. 5. The possible factors and relationship between intestinal iron absorption and hepatic parenchymal cell damage has been discussed.
