Background: The cell cycle-dependent enzyme thymidine kinase 1 (TK1) is known to increase during cancer cell proliferation and has been reported as a prognostic marker for various hematologic malignancies and solid tumors. This study aimed to determine the reference interval in Korean healthy controls and to evaluate the usefulness of TK1 as a biomarker for aggressive clinical behavior in B-cell lymphoma patients. Methods: We enrolled 72 previously untreated patients with B-cell lymphoma and 143 healthy controls. Serum TK1 levels were measured by chemiluminescence immunoassay ($Liaison^{(R)}$, DiaSorin, USA). We established the reference intervals in healthy controls. The diagnostic performance of serum TK1 was studied using receiver operating characteristic (ROC) analysis, and the correlation between the cutoff level for serum TK1 and clinical characteristics of B-cell lymphoma was evaluated. Results: The reference range (95th percentile) of serum TK1 in healthy controls was 5.4-21.8 U/L. There was a clear difference in TK1 levels between patients with B-cell lymphoma and healthy controls ($40.6{\pm}68.5$ vs. $11.8{\pm}4.4U/L$, P <0.001). The area under the curve of serum TK1 for the diagnosis of B-cell lymphoma was 0.73 (cutoff, 15.2 U/L; sensitivity, 59.7%; specificity, 83.2%). An increased TK1 level (${\geq}15.2U/L$) correlated with the advanced clinical stage (P <0.001), bone marrow involvement (P =0.013), international prognostic index score (P =0.001), lactate dehydrogenase level (P =0.001), low Hb level (<12 g/dL) (P =0.028), and lymphocyte count (P =0.023). Conclusions: The serum TK1 level could serve as a useful biomarker for aggressive clinical behavior in B-cell lymphoma patients.

Recently changes in thyroid physiology during acute and chronic medical illness were demonstrated. The serum $fT_3,\;rT_3,\;T_4,\;T_3,\;fT_4$, and TSH concentration were measured by radioimmunoassay method in 49 patients with critical illness and 10 normal subjects to assess the change of thyroid function in critical illness. The results were as follows; 1) The mean serum $fT_3$ concentration was $6.68{\pm}1.05pmol/ml$ in normal subjects while in patients with critical illness the serum $fT_3$ concentration was significantly lowered to $1.55{\pm}1.15pmol/ml$(p<0.001). 2) The mean serum $rT_3$ concentration was $0.22{\pm}0.44ng/ml$ in normal subjects and $0.42{\pm}0.37ng/ml$ in patient with critical illness. There was increment in critically ill patients as compared to normal subjects but no statistically significant difference(p>0.05). 3) The mean serum $T_3$ concentration was $1.24{\pm}0.25ng/ml$ in normal subjects and $0.56{\pm}0.56ng/ml$ in patients with criticial illness and there was significant difference in each other(p<0.005). 4) The mean serum $T_4,\;fT_4$, and TSH concentrations were $7.80{\pm}1.02{\mu}g/dl,\;1.26{\pm}0.39ng/dl,\;1.87{\pm}0.45{\mu}U/ml$ in normal subjects respectively and $6.02{\pm}3.06{\mu}g/dl,\;1.46{\pm}0.80ng/dl,\;1.74{\pm}0.79{\mu}U/ml$ in patients with critical illness and there was no significant difference between critically ill patients and normal subjects. 5) The ratio of mean serum concentration of $fT_3$ and $rT_3(fT_3/rT_3)$, $30.42{\pm}5.58$ in normal subjects was significantly higher(p<0.005) than the coresponding patients with critical illness. 6) The mean serum $fT_3$ concentration in expired cases(n=12) during admission was significant difference between expired and survived cases(p<0.005). The mean serum $rT_3$ centration was $0.67{\pm}0.58ng/ml$ in expired cases and $0.34{\pm}0.22ng/ml$ in survived cases with significant difference(p<0.005). Half of the cases who showed less than $3{\mu}g/dl$ of serum $T_4$ level were expired.

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.

Twenty three healty women on self - selected diet were given 800IU of tocopherol daily for 4 weeks. The levels of tocopherol in plasma and red blood cells( RBC ) and total choles terol, TG, HDL- chol, HDL subfractions and lipoprotein pattern in serum were determined pre-and postregimen at 2 and 4 weeks. No significant change was noted in VLDL, LDL, HDL fraction and LDL/HDL ratio separated by electrophoresis, even though HDL fraction was decreased at 2 wk but slightly increased at 4 wk. There were also no significant changes in the relative amount of HDL-chol and VLDL-chol when cholesterol content of each lipoprotein fraction was assayed. A transient increase in LDL-chol was observed at 2 wk but returned to the pretreatment level. Plasma and RBC tocopherol levels were significantly ( p ^lt;0.05 ) increased and decreased respectively, at both 2 and 4 wk, and LDL-chol was positively correlated to plasma tocopherol level ( p<0.05 ) but not to RBC tocopherol. However HDL-chol fractionated by heparin-Mn was increased at 2 and 4 wk by a significant increase in $HDL_{2}$-chol but no change in $HDL_{3}$-chol, which resulted in a significant reduction of $HDL_{3}$/HDL ratio and increase of $HDL_{2}/HDL$ and $HDL_{2}/HDL_{3}$ ratios. HDL- chol was negatively correlated to the levels of LDL-chol ( p<0.05), VLDL-chol (p<0.01), and T-chol/HDL ratio ( p<0.01 ). Serum TG was significantly decreased ( p <0.05 ) but total cholesterol was decreased only at 4 weeks.

The methanolic extract of natural roots of Mucuna pruriens was screened for hepatoprotective and antioxidant effects in carbon tetrachloride ($CCl_4$) induced hepatotoxicity in Albino rats. The degree of protection was measured by estimating biochemical parameters like serum glutamate oxaloacetate transaminase, serum glutamate pyruvate transaminase, total protein and level of serum bilirubin (both total and direct). The extract also reduced $CCl_4$ induced lipid peroxidation both in-vitro and in-vivo. Hepatoprotective activity of methanolic extract at dose 300 mg/kg body weight, i.p., was comparable with standard drug Silymarin (25 mg/kg, i.p.). Furthermore, histopathological experiments were also carried out to support the study.

This study was performed to investigate the serum lipid levels and fatty acid composition in middle-aged men and the influence of cardiovscular risk factors on them. Data for dietary intake, anthropometry , blood pressure, and general environmental factors were obtained and their relationship to serum lipid levels and fatty acid composition were analyzed in 303 healthy male subjects with a mean age of 43.8$\pm$6.4 years from June 1 to 22 , 1995. The prevalence of obesity was 26.7% by BMI and 11.2% by WHR criteria . The percentage of hypertensive subjects were 13.5% and 22.4% by systolic and diastolic blood pressure, respectively. Retinol, calcium , and roboflavin intakes were lower than the RDA for Koreans. The ratio of carbohydrate intake to total calories of the subjects was 70%. Ratios of P/M and n-6/n-3 were 1.02/1.05/1.00 and 11.1/1, respectively. The percentage of subjects who had serum TG, TC, LDL-C leves beyond the normal range were 19.5% , 13.5% and 8.6% respectively. Palmitic comprised 26.4% of serum total fatty acids, linoleic acid 19.4% and oleic acid 16.4. The waist circumference and ration of carbohydrate intake were related positively to TG level. Serum cholesterol level had positive relations with waist circumference, DBP, sugar intake, and income. There were positive relationships between SFA and bone fishes and vegetable oil intakes, MUFA and DBP while a negative a negative relationship was observed between PUFA and animal fat intake. Serum n-6 fatty acid was related negatively to carbohydrate intake and hot taste preference. N-3 fatty acid was related positively to fish intake and negatively to egg intake. These results suggest that to maintain adequate serum lipid levels and fatty acid composition, sugar, animal fat, and carbohydrate intakes have to be reduced, while consumption of vegetable oil and fish must be increased. It is also essential to control abdominal fat accumulation and blood pressure.

This study aims to address the effect of interferential current therapy and thereby to provide basic resources to physical therapies for internal medicine by identifying symptoms for functional dyspepsia and serum gastrin level that shows gastric motility. Following results were obtained by performing interferential current therapy to 16 subjects composed of 8 for functional dyspepsia group and 8 for control group for 20 minutes a day, 3 days a week, for 6 weeks. In control group, serum gastrin level was significantly( p<.01), lowered after the therapy whereas there was no significant difference observed in all questions from questionnaire for symptoms of functional dyspepsia between before and after the therapy. In functional dyspepsia group, serum gastrin level was significantly(p<.01), lowered after the therapy and there was also significant(p<.01) reduction in every question from questionnaire for symptoms of functional dyspepsia between before and after the therapy. There was more significant decrease in serum gastrin level and reduction in questionnaire for symptoms of functional dyspepsia in the functional dyspepsia group compared to the control group(p<.01). This study confirms the interferential current therapy as an effective therapeutic method for internal diseases including functional dyspepsia since it not only improves the symptoms of functional dyspepsia but also allows the gastric motility close to normal.

The purpose of this study was to investigate the relationships among serum adiponectin, leptin and vitamin D concentrations and the metabolic syndrome in Korean farmers. 105 (26 males, 79 females) farmers (39~78 years, mean age $59.4{\pm}9.6$ years) in Gangwon - area were included in this study. Anthropometric measurements and biochemical blood analysis of subjects were carried out. The prevalence of obesity, abdominal obesity, hypertension, diabetes, hypertriglyceridemia, hypercholesterolemia and hyper LDL-cholesterolemia, metabolic syndrome were 51.9%, 65.7%, 49.5%, 15.3%, 17.3%, 13.5%, 11.5% and 40.9%, respectively. Serum adiponectin and leptin levels ($8.90{\mu}g/ml$ and 12.6 ng/ml) of females were significantly higher than those ($6.49{\mu}g/ml$ and 4.88 ng/ml) of males. But there was no significant difference in 25(OH)vitamin D concentration between males (15.4 ng/ml) and females (16.9 ng/ml). In the subjects with metabolic syndrome, the adiponectin levels were significantly lower and leptin levels were significantly higher than those of the subjects without metabolic syndrome. Serum adiponectin level had positive correlations with HDL-cholesterol level (r = 0.325, p < 0.001), but showed negative correlations with triglyceride and fasting blood glucose concentrations, body weight and waist/hip circumference ratio (r = -0.202 ~ -0.317, p < 0.05). Serum leptin and 25(OH)vitamin D concentrations were positively correlated with body fat (kg, %) and BMI, waist and hip circumferences (r = 0.244 ~ 0.682, p < 0.001). The results of this study suggested that adiponectin and leptin levels could be credible indices to predict chronic diseases in farmers. However, further research on vitamin D should be carried out considering another factors.
