  • Triiodothyronine[T3] is an important regulator of the tissue metabolism, and may have potential use as an inotropic agent. The change of serum T3 level was studied in the pediatric age patients after cardiopulmonary by pass. Thyroid function was tested pre-operatively in 33 patients and total triiodothyronine[TT3] levels were serially measured during and after cardiopulmonary bypass[CPB]. After correction of dilutional effect, effects of various factors on the TT3 levels were analyzed. Abrupt fall of TT3 level was demonstrated at 15 minutes after CPB[80.1$\pm$5.9ng/dL] from the initial level of 133.6$\pm$5.3ng/dL, with some recovery at 6 hours[115.4$\pm$6.7ng/dL]. After then, gradual decrease occured reaching to the level of 77.2$\pm$4.2ng /dL at 24 hours. These falls of the TT3 after CPB were statistically significant. [p<0.01 ANOVA] Statistically significant correlation were found between the degree of hemodilution and TT3 concentration at 15 and 30 minutes after CPB[p<0.05]. But, other factors were analyzed to have no effect on TT3 levels. As the degree of the hemodilution increases, TT3 decreased less. This observation probably supports the fact that decrease of TT3 during CPB may be a result of sequestration of T3 into peripheral tissue. Although it was not statistically significant[p=0.08], the fall of TT3 was greater in the group to which plasmanate was added, than those not added. This finding seemed to be due to the increase of albumin and other thyroid-hormone-binding-proteins in the serum. Increase of these binding proteins might potentiate the sequestration of T3 into the liver and the kidney from serum, and as a consequence, decrese the serum TT3 level further.

  • A nebumetone tablet in development $(Navuton^R)$ was tested for its bioequivalence to the erference tablet $(Uniton^R)$. Seventeen healthy Korean male subjects participated in this study. Each subject received a 1-g dose of nabumetone (2tables each) in an unbalanced, randomized, two-way crossover investigation. Serum concentrations of 6-methoxy-2-na-phthylacetic acid (6-MNA), a major metabolite of nebumetone, were measured over 120 hr interval by a high-performance liquid chromatography. The maximum serum concentration $(C_{max})$ and time to reach the maximum concentration$(T_{max})$ were read directly, but area under the serum concentration time curve from time 0 to 120 hr (AUC) and mean residence time serum curves showed multiple peaks of 6-MNA in most subjects, and the $C_{max}$ and $T_{max}$ were read from the highest serum peaks. calculated bioavailability parameters for test and reference tablets were 148.6 : 1377.9 $\mug \cdot hr/ml$ for AUC; 25.2:23.1 $\mu/ml$ for $C_{max}$; 11.8:16.4 hr for $T_{max}$, and 42.6 : 43.8 hr for MRT, respectively. The paired t-test revealed no significant differences in all the parameters between the two tablets. Analysis ofl variance (ANOVA) revealed no significant differences between groups and formulations in all the parameters ($C_{max}$ and $T_{max}$, AUC and MRT) indicating the crossover design of the experiment was properly performed. But significant differences (p<0.05) between subject/groups and periods were found for all the parameters indicating substantial intersubject and interperiodic variations for these parameters.

  • Background: We tested the hypothesis that dengue haemorrhagic fever (DHF) is associated with a $T_H1$-skewed immune response as opposed to dengue fever (DF). Methods: We estimated intracellular (in T-cells) and serum levels of designate $T_H1/T_H2$ cytokines [interferon-${\gamma}$ (IFN-${\gamma}$), interleukin-4 (IL-4), and tumor necrosis factor-${\alpha}$] and macrophage inflammatory protein-$1{\alpha}$ (MIP-$1{\alpha}$) at admission, 48h, and day 5 in 20 adults with dengue (DF=10, DHF=10) and 10 dengue-naive healthy controls. Results: At admission, intracellular IFN-${\gamma}$/IL-4 ratio in CD4+ T-cells and proportion of MIP-$1{\alpha}$-positive CD8+ T-cells were significantly higher in patients with DHF [7.21 (5.36~10.81) vs. 3.04 (1.75~4.02); p=0.011 and 6.2% (3.2~8.2%) vs. 2.4% (2.0~3.6%); p=0.023]. The latter showed a significant positive correlation with IFN-${\gamma}$/IL-4 ratio in CD4+ T-cells (Spearman's rho=0.64; p=0.003), percentage-change in haematocrit (rho=0.47; p=0.048), and serum alanine amino-transferase level (rho=0.61; p=0.009). Conclusion: We conclude that DHF is associated with a $T_H1$-skewed immune response. Further, MIP-$1{\alpha}$ in CD8+ T-cells is an important immunologic correlate of disease severity in dengue.

  • In this study we investigated the effects of dietary fat sources and onion on serum lipid levels in rats. One hundred twenty female Wistar rats two weeks old were randomly divided into five groups of 24 animals assigned to one of the ive modalities : Control group was fed only basal diet containing 6.3% of corn oil, T and L group were administered 6.3% beef tallow and lard substituted for corn oil in basal diet, LOv and LOx group were given same amount of lard as L group together with 4.2ml of onion juice/kg body weight, and 8.2ml of onion juice/kg body weight respectively. Six randomly selected rats from each group were evaluated for hematologic and serum biochemical parameters weekly. Over 4 week experiments it was found that the triglyceride and cholesterol levels were significantly elevated in T and L group compared with the control group. Triglyceride contents were significantly increased in L group compared with T group. But there was no difference in cholesterol levels between L and T group. LOv diet did not decrease significantly the triglyceride and cholesterol levels, but LOx group significantly did compared with L diet. LOx group had nearly normal values of bilirubin, creatinine, uric acid level and hemoglobin contents cut slightly increased levels in the glutamic oxaloacetic transaminase and alkaline phosphatase activities.

  • The purpose of this study was examine the relationship between smoking, general characteristics, and serum lipids in the normal adult. The subjects consist of 6,800 persons (male ; 4,309(63.4%), female ; 2,491(36.6%)) in A hospital in Kyungki-Do. The collected data were analyzed using T-test, and Multiple Regression by SPSS/WIN program. The result were following ; 1. Cigarette smoking was associated with decreased serum HDL cholesterol level (p<.001). 2. Serum LDL cholesterol level was not statistically correlated with smoking tend to level by 5.77mg/dl respectively. 3. Cigarette smoking was associated with elevated serum Triglyceride level (p<.001). 4. By using regression, HDL cholesterol level was negatively correlated with obesity and alcohol.. HDL cholesterol level was positively correlated with exercise. LDL cholesterol level was positively correlated with diet and obesity. Triglyceride level was positively correlated with obesity and alcohol. In conclusion, Smoking was the most correlated with Triglyceride among the serum lipid and Serum lipid was the most correlated with obesity. Thus, it is necessary to quit smoke and weight control for prevention from disease such as coronary heart disease and lung cancer.

  • Fat and fatty acids in muscle and adipose tissues are among the major factors influencing meat quality particularly nutritional value and palatability. The present study was carried out to examine the effects of supplementing inorganic selenium (Se), iodine (I) and a combination of both on fatty acid compositions in serum, and supraspinatus (SS), longissimus lumborum (LL), and semitendinosus (ST) muscles in goats. Twenty-four, 7 to 8 months old, Kacang male goats with a mean live weight of $22.00{\pm}1.17kg$ were individually and randomly assigned into four groups of six animals each for 100 d of feeding prior to slaughter. The animals were offered the same concentrate (basal) diet as 1% of body weight with ad libitum amount of fresh guinea grass. The four groups were as follows: T1 (control) - basal diet without supplementation; T2 - basal diet with 0.6 mg Se/kg DM; T3 - basal diet with 0.6 mg I/kg DM; T4 - basal diet with combination of 0.6 mg Se/kg DM and 0.6 mg I/kg DM. The major fatty acids (FAs) detected in the serum were palmitic (C16:0), stearic (C18:0), oleic (C18:1n9) and linoleic (C18:2n-6), while the major FAs in the selected muscles were C16:0, C18:0 and C18:1n9 acids. The main polyunsaturated fatty acids (PUFA) detected in muscles and serum were (CI8:2n-6), linolenic acid (C18:3n-3), and arachidonic acid (C20:4n-6). No significant differences (p>0.05) were observed in the concentration of total saturated fatty acids (SFA) among the four groups. PUFA concentrations in the goats supplemented with Se (T2) were significantly higher (p<0.05) than the goats of the control group (T1). The PUFA: SFA ratio was significantly higher in the animals supplemented with dietary Se (T2) than those of control ones (T1). It is concluded that dietary supplementation of inorganic Se increased the unsaturated fatty acids in muscle. The supplementation of iodine with or without Se had negligible effects on muscle fatty acid content of Kacang crossbred male goats.

  • This study was carried out in 14,443 subjects(8,706 men, 5,737 women, mean age $41.8{\pm}9.16$) who visited the health promotion center of one university hospital. Serum $T_3$, $T_4$ and TSH concentrations were measured with CIA using commercial kits on ADVIA Centaur Assay and Serum total cholesterol, triglyceride, and HDL-cholesterol were measured by auto-analyzer Hitach 7600 in enzyme method. 1. The prevalence of subclinical hypothyroidism was 12.6/1,000 population(men 6.0/1,000, women 22.7/1,000) and as high as about 4 times in women than in men. 2. In subclinical hypothyroidism, the values of total cholesterol and LDL-cholesterol were significantly high by 5.5 mg/dL, 4.6 mg/dL compared with normal group(p<0.05). 3. In all the tested hypercholesterolemia and hyperLDL-cholesterolemia, were correlated with TSH. There is higher correlation in women group than men group. These results indicate that the subclinical hypothyroidism and dyslipemia significantly correlated. Especially, it is very important to find that the hypercholesterolemia and hyperLDL-cholesterolemia are the high risk factors of atherosclerosis. Therefore, it is essential for the group of subclinical hypothyroidism to take the cholesterol, LDL-cholesterol and serum lipid test as well as thyroid function test.

  • This study was conducted to investigate feeding effects of the high pressure boiled extract(HPBE) of the Ogol chicken on weight gain and serum lipid composition of rat. Rats(S.D,♂) were fed with normal feed(T$_1$), normal feed + herb HPBE(T$_2$), normal feed + Ogol chicken HPBE(T$_3$), normal feed + mixture of cross­bred Ogol chicken HPBE hydrolyzed with Flavourzyme 0.1% for 35 days. During experimental period, the effects of the treatments on growth performance, plasma triglyceride(TG) and cholesterol were determined. The effects of feeding HPBE on growth performance and serum triglyceride levels in rat. After a 6 day treatment, body weights were 39.96g, 44.56g, 43.34g, and 45.99g for T$_1$, T$_2$, T$_3$ and T$_4$ groups respectively. The growth rates of T$_2$ and T$_4$ groups were significantly(P<0.05) higher than T$_1$ group, but the differences were not observed after 18 days of feeding period. Triglyceride contents were 62.89${\pm}$6.24mg/dl, 55.70${\pm}$6.76mg/dl, 43.60${\pm}$4.68mg/dl and 45.00${\pm}$3.75mg/dl for T$_1$, T$_2$, T$_3$ and T$_4$ groups respectively, where T$_1$ group was significantly (P<0.05) higher than T$_3$ and T$_4$ groups. In serum total cholesterol contents, there was no significant difference among the groups. GOT(glutamic oxaloacetic transaminase) and GPT(glutamic pyruvic transaminase) also showed similar levels among the treatments.

  • Objective : Previous studies reported a correlation between the low serum cholesterol level and impulsive behaviors. In this study, we investigate an association between the serum lipid levels and psychological parameters in maladaptive soldiers in the Korean Army. Methods : A total of ninety-six maladaptive subjects and thirty-six normal controls in the Korean army were evaluated with the Korean version of Barratt Impulsiveness Scale (K-BIS), Korean version of Beck Suicidal Ideation Scale (K- BSIS), Korean version of Beck Depression Inventory (K-BDI) and Korean version of Beck Anxiety Inventory (K-BAI). Serum total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and high density lipoprotein (HDL) level were measured by overnight fasting blood sampling. Results : There were no significant differences between the groups in demographic characteristics. Serum total cholesterol levels (t=-2.209, p=0.032), triglyceride levels (t=-4.593, p<0.001), and LDL levels (t=-3.753, p=0.001) of maladaptive subjects were significantly lower than those of normal controls, and maladaptive subjects had higher K-BIS scores than normal controls (t=7.542, p<0.001). Negative correlation was found between LDL levels and non-planning impulsiveness in the maladaptive subjects (r=-0.253, p=0.013). LDL levels (${\beta}=-0.258$, p=0.008) and K-BDI scores (${\beta}=0.266$, p=0.043) emerged as significant predictors for non-planning impulsiveness. Conclusion : These results suggested that LDL level was associated with non-planning impulsiveness. These findings suggested that serum cholesterol levels might be available as a biological marker of impulsiveness. However, more large samples, longitudinal biological study and psychiatric evaluations should be needed to develop a preventive intervention for maladaptive male conscripts in the Korean army.
