  • Mouse guanylate-binding protein 3 (mGBP3) is a 71-kDa GTPase which belongs to GTP-binding protein family. The present study showed that the expression of mGBP3 transcript was readily induced in a dose dependent fashion in the macrophage cell line RAW264.7 treated with either $interferon-{\gamma} (IFN-\gamma)$ or lipopolysaccaride (LPS). The expression of mGBP3 protein was also apparent by 4 and 6 h after the treatment of cells with IFN-\gamma (100 U/ml) or LPS ($1{\mu}g/ml$) , and remained at palteau for at least 24 h. Cycloheximide ($10{\mu}g/ml$) had no effect on the $IFN-\gamma-$ or LPS-induced mGBP3 expression, suggesting that the mGBP3 induction did not require further protein synthesis. Interestingly, a protein kinase C (PKC) inhibitor staurosporine (50 nM) abolished the induction of mGBP3 expression by LPS, but not by $IFN-{\gamma}$. These findings suggest that mGBP3 may be involved in the macrophage activation process and both IFN-\gamma and LS induce the mGBP3 expression through distinct signal transduction pathways.

  • The quality characteristics and physiological effects of chunggukjang fermented naturally (NF-c), with Bacillus subtilis-SKm (BS-c), with Bacillus subtilis HJ18-4 (BH-c), and with Bacillus subtilis KCCM 42923 (BK-c) were investigated. The characteristics of fermentation were determined by protease, ${\alpha}$-amylase and ${\gamma}$-GTP activities, and additionally the amounts of amino-type and ammonia-type nitrogens. BS-c showed the highest protease, ${\alpha}$-amylase, and ${\gamma}$-GTP activities, and also amino-type nitrogen content among the four types of chunggukjang. The ammonia-type nitrogen content in BS-c was similar to that of BK-c and NF-c. BH-c showed the lowest enzyme activities and amino-type and ammonia-type nitrogen content. BS-c, BH-c, BK-c, and NF-c showed a similar overall acceptability during sensory evaluation. BS-c also showed the strongest DPPH free radical scavenging and anti-proliferative activities in HT-29 human colon carcinoma cells. These results suggested that B. subtilis-SKm was suitable to be used as a starter to enhance the quality and effects of chunggukjang.

  • In this study, we tested the influences of several ${\kappa}$ opioid ligands on the $[^3H]diprenorphine$ binding in rat and guinea pig cortex membrane preparations. Using paradigm to block ${\mu}\;and\;{\delta}$ opioid receptors with $DAMGO(1{\mu}M)$ and $DPDPE(1{\mu}M)$, $[^3H]diprenorphine$ labeled ${\kappa}$ sites. Competition analysis in both rat and guinea pig cortex has shown a single population of $[^3H]diprenorphine$ binding site with different Kd values, respectively. There is a significant difference in Ki values of (-) WIN44441 and (+)WIN44441 in both rat and guinea pig cortex. Bremazocine, (-)ethylketocyclazocine, (-)cyclazocine, nor-binaltorphimine effectively inhibited the $[^3H]diprenorphine$ binding with different Ki values in rat and guinea pig cortex. U-69,593, U-50,488H and dynorphine-A (1-8) did not inhibit the $[^3H]diprenorphine$ binding in rat but in guinea pig cortex. Nor-binaltorphimine was a ligand discriminate the ${\kappa}_1$, and ${\kappa}_2$ receptor most effectively. We, also, examined the influence of Na ion and $GTP{\gamma}S$, a nonhydrolyzable guanine nucleotide analog, on the inhibition of $[^3H]diprenorphine$ binding by diprenorphine, (-)ethyl-ketocyclazocine, U-69,593 and bremazocine. By the replacement of NaCl with N-methy-D-glucamine or addition of $GTP{\gamma}S$, Ki values of diprenorpnine were not changed and that of ethylketocyclazocine were changed significantly in both rat and guinea pig cortex. The Ki value of bremazocine was decreased by removal of Na ion, and increased by $GTP{\gamma}S$, however, was not changed by any one of either. These results suggest that there are 2 kinds of subtypes of ${\kappa}$ opioid receptor, ${\kappa}_1$, and ${\kappa}_2$, showing different Ki values for various ${\kappa}$ opioid ligands, also, bremazocine possess the antagonistic property at ${\kappa}_2$ site which is dominant subtype of K receptor in rat cortex.

  • Workers' periodic health examination is the main tools used to manage the health problems of most workers in Korea. The most common health problem found in workers' periodic health examination is liver disorder. Liver disorder is also one of the most common health problems in general population and one of the leading causes of mortality in adult population. Regulation proposed by government (No. 207, Ministry of Labor, 1992) defines the criteria for selection of workers with the liver dysfunction for further evaluative examination and the examination items used for diagnosis of the workers with liver dysfunction. This study was designed to evaluate the proficiency of each examination items presently defined in Regulation and propose the optimal examination items for detection of the liver disorders found by workers' periodic health examination. Study subjects are 186 workers with abnormal liver function tests in screening examination of workers' periodic health examination. Questionnaire survey including past history of liver disorder, drinking history, height and weight was done. Physical examination by physician, routine test items defined by Regulation (SGOT, SGPT, $\gamma$-GTP, protein, albumin, total and direct bilirubin, alkaline phosphatase, $\alpha$-feto protein, HBsAg and anti-HBs), anti-HCV antibody test and liver ultrasonography were done. Results are as follows; 1. Result of evaluative examination utilizing only the items defined in Regulation was; There were 75 workers with suspected live. disorder(40.3%), 63 with no liver dysfunction (33.9%), 13 with suspected hepatitis B(7.0%), 10 workers with hepatitis B(5.4%), 10 workers with hepatitis B carrier state(5.4%), 10 with alcoholic liver disorders(5.4%), 5 with fatty liver(2.7%). When alternative diagnostic criteria applying additional examination items (drinking history, body mass index, anti-HCV antibody and ultrasonography) diagnosability of liver disorder was increased. When all four items were included, final results were; 23 workers (17.8%) with hepatitis B (10 carriers, 13 suspects and 10 hepatitis B), 10 (5.4%) with hepatitis C(4 carriers, 5 suspects and 1 hepatitis C), 13(7.0%) with alcoholic liver disorder, 45(24.2%) with fatty liver (40 suspects, 5 fatty liver), 410%) with suspected liver disorders and 44 (23.7%) with normal liver. 2. Of examination items defined by Regulation, only SGOT, SGPT, $\gamma$-GTP and HBsAg were significantly different in abnormal rate and mean value, and all other laboratory findings did not showed significant difference between two groups. Drinking history, body mass index and anti-HCV antibody test which are the items that authors included in this study, also showed significant difference between two groups. Utilization of body mass index (BMI) for abnormal liver function group in diagnosis of fatty liver had high specificity (97.6%) but sensitivity (22.3%) was low. Therefore we suggest that SGOT, SGPT, $\gamma$-GTP, HBsAg, alcohol drinking history, BMI and anti-HCV Ab were useful for diagnosis of liver disorders among worker's periodic health examination.

  • In order to study the effects of Daebangpungtang on galactosamine induced hepatoxity in rats, the experimental rats divided five groups (Normal, Control, Sample A, B, C groups). Under the same condition, normal and control groups were administered normal saline for 16 days, control group was injected to abdomen with galactosamine at 8th day (800mg/kg). Sample A group was administered the Daebangpungtang aqueous solution($200m{\ell}/kg$ p.o) for 8 days and injected galactosamine(800mg/kg i.p) for the last day and was administered normal saline for 8 days. Sample B group was treated as same as group A for 8 days, and then was administered the Daebangpungtang aqueous solution($200m{\ell}/kg$ p.o) forfurther 8 days. Sample C group was administered the Daebangpungtang aqueous solution($200m{\ell}/kg$ p.o) for 16 days. The activity of GOT, GPT, ${\gamma}$-GTP, ALP, LDH and total bilirubin in serum were measured at 8th and last day. The results were obtained as follows: 1. The activity of serum GOT of the sample A group decreased effectively at the 8th day and sample B group decreased effectively at 16th day as compared with the control group. 2. The activity of serum GPT of the sample A group decreased effectively at the 8th and 16th day and sample B group decreased effectively at 16th day as compared with the control group. 3. The activity of serum ${\gamma}$-GTP of the sample B group decreased effectively at the 16th day as compared with the control group. 4. The activity of serum ALP of the sample A group increased respectively at the 8th and 16th day and sample B group decreased effectively at 16th day as compared with the control group. 5. The activity of serum LDH of the sample A, B groups decreased effectively at 16th day as compared with the control group. 6. The activity of serum total bilirubin of the sample A, B groups decreased effectively at 16th day as compared with the control group. 7. The activity of GOT, GPT, ${\gamma}$-GTP, ALP, LDH and total bilirubin in serum of the sample C group were analogous with thats of normal group.

  • Objectives : The purpose of this study was to determine whether NMED-01 or NMED-02 improves laboratory test results in participants with liver function disorder. Methods : This is a randomized, placebo-controlled trial in which participants, treating physicians and data management staff were blinded to treatment group. The study was conducted at Semyung university oriental medicine hospital in Jecheon where participants with high level of serum ${\gamma}$-GTP (60-350 U/L) were enrolled. The intervention consisted of three times daily ingestion of either two capsules of placebo, NMED-01 (NeuMed. co. ltd., Seoul), or NMED-02 (NeuMed. co. ltd., Seoul) for twelve weeks. To evaluate the efficacy and safety of NMED-01 and NMED-02, we primarily evaluated the degree of decrement of serum ${\gamma}$-GPT level among three groups. Secondarily the decrement of serum ALT, AST, and triglyceride level in each group were also evaluated. Adverse effects were monitored during the twelve weeks treatment. Results : The change of ${\gamma}$-GTP level of NMED-01 group was lower than that of placebo group at the end of 12-week administration ($28.1{\pm}38.7U/L$ vs. $9.3{\pm}27.0U/L$, p=0.046). Other variables including AST, ALT, and triglyceride level were not significantly reduced. The decrement of ${\gamma}$-GPT, AST, ALT, and triglyceride level of NMED-02 group was not significant. There were no significant adverse effects or toxicities during treatment period. Conclusions : Participants receiving NMED-01 had improvement in laboratory test results. Despite a modest sample size, our results suggest that NMED-01 are safe and may be potentially effective in improving liver function. However, NMED-02 have lack of a detectable effect in this study.

  • Studies on the health problems of the elderly have been increased with increasing life expectancy of Koreans. To assess the health status of people over 50 years old including the elderly (678 free-living people: men (168), women (510)), anthropometric measurements and biochemical nutritional status were analyzed. General characteristics and the prevalences of specific diseases were also examined. The mean anthropometric values for males and females were heights of 162 cm and 149 cm, respectively; and weights of 59 kg and 52 kg, respectively, which were much lower than the Korean standards established in the Korean Recommended Dietary Allowances. The mean BMI, WHR (waist hip ratio), and body fat rate (%), which are obesity indices, were significantly higher in females than in males. As the age went up, height, weight, lean body mass, and mid-arm circumference decreased. Whereas, blood pressure (SBP) for women increased. Mean blood HDL-cholesterol levels of men and women were 46.0 mg/dl and 46.3 mg/dl, respectively; their triglyceride levels were 129.1 mg/d1 and 135.6 mg/dl, respectively, which were not significantly different. Total cholesterol and LDL-cholesterol levels were significantly higher in females than in males. For man there were significantly different in ${\gamma}$-GTP, Na levels by age. As the age went up for women, RBC, hemoglobin, hematocrit, HDL-cholesterol, ${\gamma}$-GTP and $Ca^{2+}$ levels significantly decreased. Levels of total protein and albumin were above the lower normal limit for the majority of the participants. Prevalence of anemia, assessed by hemoglobin using World Health Organization (WHO) definition, was 43.9% for men and 42.1% for women. Also, many of the subjects were out of the normal range in total cholesterol (women), HDL-cholesterol, TAS (total antioxidant status), APase, RBC, hemoglobin, hematocrit levels. Therefore, measures to improve the biochemical nutritional status for the people in rural area are required.d.
