  • In other to establish the exact determination method of amino nitrogen (AN) in salt-fermented fish sauces, we determined the AN in fish sauces according to the measuring methods and also investigated the main factors influencing on determination method of AN. AN in salt-fermented anchovy sauce increased linearly as fermentation progressed, and was shown the highest amount measuring by the Formol method, followed by the trinitrobenzene sulfonic acid (TNBS) method and the Copper-salt method. AN concentration in anchovy sauces fermented for 12 months was $88.2\%$ and $77.6\%$ for the TNBS method and the Copper-salt method, respectively, on the basis of Formol method. The ratio of AN/total nitrogen (TN) in anchovy sauce fermented for 12 months was higher than that in commercial anchovy sauces. The determination of AN in anchovy sauce by the TNBS method was not affected by salt concentration, and slightly affected by heating. The effect of MSG on AN contents by Copper-salt method was shown higher than those by the Formol method and the TNBS method. The TNBS method was adaptable to measure the content of AN in fish sauce by this study.

  • Objectives : Crohn's disease is a severe chronic inflammation that is treated mainly by immunosuppression, which often has serious side effects. There is need to develop new therapeutic methods or drugs that have few side effects in order to treat this disease. Acupuncture with Moxi-tar at Cheonchu (ST25) has anti-inflammatory properties, but the mechanism of its anti-inflammatory actions is unclear. We investigated the protective effects and speculated the mechanisms of acupuncture with Moxi-tar at ST25 on trinitrobenzene sulfonic acid (TNBS) induced colitis in mice which is a well known Crohn's disease animal model. Methods : 5 % TNBS was treated at day 1 and day 7 into rectum of mice. To investigate therapeutic effects of acupuncture with Moxi-tar at ST25, acupuncture was carried out on day 3, and day 6. For the data analysis, we observed macroscopic and microscopic findings of the colon. Weight and width of the colon, degree of damage, changes of body weight, and myeloperoxygenase (MPO) activity were checked. For analysing protein expression, we carried out immunohistochemical staining and Western blot. For analysing mRNA expression, RT-PCR was carried out. Results : TNBS induced damages on the colon of mice, while acupuncture of Moxi-tar at ST25 suppressed TNBS mediated damages similar to those on the colons of mice in the control (not treated with TNBS) group. The average body weight of TNBS treated mice (77.4%) was decreased compared with that of the control mice (105%), and acupuncture with Moxi-tar at ST25 suppressed the loss of body weight caused by TNBS (from 77.4% to 95.3%). TNBS induced infiltration of immune cells in all layers of the colon while acupuncture with Moxi-tar at ST25 suppressed infiltration of immune cells caused by TNBS. Furthermore, acupunctured with Moxi-tar at ST25 suppressed macro-, micro- colonic damages caused by TNBS. Acupunctured with Moxi-tar at ST25 dramatically improved the clinical and histopathological symptoms such as the increase in weight of the distal colon and the MPO activity in TNBS-induced colitis. Acupuncture with Moxi-tar at ST25 down-regulated the nuclear transcription factor kappa B ($NF-{\kappa}B$) activity and suppressed tumor necrosis factor-a (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-1${\beta}$), and intracellular adhesion molecule-1 (ICAM-1) expressions caused by TNBS. Conclusions : Acupuncture with Moxi-tar at ST25 helps recovery from the TNBS-induced colonic damage by down-regulation of $NF-{\kappa}B$ activity and suppressing of TNF-${\alpha}$, IL-1${\beta}$, and ICAM-1 expressions. This may be an important method for the treatment of Crohn's disease.

  • In order to establish the exact determination method of amino nitrogen in fish sauces, we compared the amino-nitrogen content in salt-fermented sand lance sauces according to the measuring methods and investigated influencing factors on the procedure of measuring. Amino-nitrogen content was increased in both sand lance sauce during fermentation periods and commercial sand lance sauces. Amino-nitrogen in fermented sand lance sauces for 12 months occupied 88.7% and 75.2% for the trinitrobenzene sulfonic acid(TNBS) method and the Copper-salt method, compare to the Formol method. The ratio of amino-nitrogen/total nitrogen in fermented sand lance sauce for 12 months was higher than in commercial sand lance sauces. The determination of amino-nitrogen by the TNBS method was influenced by concentration of salt in sand lance sauce. The amino-nitrogen content was the highest in the Formol method and followed by the TNBS method and the Copper-salt method without the influence of heating time and monosodium glutamate(MSG) concentration. We concluded that the determination of amino nitrogen in fish sauces was correct to measure with the TNBS method.

  • Objectives : Crohn's disease (CD) is characterized by a chronic relapsing inflammation of the bowel in which proinflammatory cytokines play an important perpetuating role. Methods : Mice (preventive animal model of gliotoxin) were treated with 5 % 2,4,6-trinitrobenzenesulfonic acid (TNBS) at day 1 and day 7. To investigate preventive effects of acupuncture with Gujin at $LI_{11}$, acupuncture was carried out at day -1, day 1, day 3. And, to investigate therapeutic effects, acupuncture with Gujin was carried out at day 3, day 5, day 7. For the data analysis, we checked weight and width of colon, diarrhea, edema, survival rate, changes of body weight, and myeloperoxygenase (MPO) activity. For analysing protein expression, we carried out immunohistochemical staining and Western blot and we analyzed mRNA expression by RT-PCR. Results : Colon of TNBS treated mice was erosive and shortening compared with the colon of control mice and induced damages of colon epithelial cell layer and induced infiltration of immune cells in all layer of colon. Acupuncture of gujin at $LI_{11}$ in preventive mode suppressed macorscopic damages such as erosive and shortening of colon by TNBS and damages of intestinal epithelial cells and infiltration of immune cells in the colon. The average weight of 5 cm distal colon was increased in TNBS treated mice (758${\mu}g$) compared with in control mice (112${\mu}g$) and width of distal colon was also increased in TNBS treated mice (4.9mm) compared with in control mice (1.3mm). Acupuncture with Gujin at $LI_{11}$ in preventive and therapeutic mode suppressed increase of colon weight and width by TNBS. TNBS induced edema of colon and diarrhea and Acupunctured with Gujin at $LI_{11}$ in preventive and therapeutic mode ameliorated these symptom by TNBS. In preventive and therapeutic mode, the effects of acupuncture with Gujin at $LI_{11}$ were increasing the motility, suppressing body weight decreasing, suppressing MPO activity, reducing expressing of TNF-${\alpha}$, IL-1b, and ICAM-1 in colon compared with that by TNBS Conclusions : This study demonstrates that acupuncture with Gujin at $LI_{11}$ represents a potential therapeutic method of Crohn's disease.

  • An osmometrical method for determination of the degree of hydrolysis (DH) of hemoglobin was comparatively examined through TNBS (trinitrobenzene) sulfonic acid) method using two experimental variables $({\alpha}\;and\;{\beta})$, which were chosen based on correlation curves between hydrolysis equivalents (h) and $leucine-NH_2$ equivalents. DH values measured through osmometry and TNBS method highly correlated with $R^2$ values of $0.974{\sim}0.991$, irrespective of the reaction pHs and types of enzyme used. $DH_{osm}/DH_{TNBS}$ was >$1.438{\sim}1.656$ depending on the hydrolysis pH $7.5{\sim}10.0)$. Correlation euqations were well fit for measuring DH of Hb hydrolysate at different pH conditions. $DH_{osm}/DH_{TNBS}$ for co-treatment system using Esperase and Flavourzyme was 1.658, in good agreement with that of 1.656 for the single enzyme (Esperase) system. Thus, the osmometrical method was suggested to be a convenient, reliable, and rapid method for determination of DH of hemoglobin hydrolysates.

  • Objectives : Inflammatory bowel disease (IBD) is a chronic relapsing inflammatory disease in the gastrointestinal tract. The sources and pathologic mechanisms of IBD are still unknown. Moreover conventional therapies for IBD are not always effective, and they often have serious side effects. The purpose of this study is to examine the effect of Moxi-tar herbal acupuncture in IBD affected mice. Methods : Mice were treated with 5 % 2, 4, 6 - trinitrobenzenesulfonic acid (TNBS) on day 1 and day 7. To assume the preemptive effect and therapeutic effect, herbal acupuncture was practiced with Moxi-tar at BL25 (Daejangsu) on day 0, day 3, and day 6. The end of day in treatment with Moxi-tar herbal acupuncture, the mortality and the inflammatory factors of the colon were measured by the various methods. Results TNBS induced high mortality but herbal acupuncture with Moxi-tar at BL25 sup-pressed the mortality caused by TNBS. TNBS induced infiltration of immune cells in all layers of the colon and increased myeloperoxygenase (MPO) activity, while the treatment with Moxi-tar herbal acupuncture at BL25 suppressed the infiltration of immune cells and the increase of MPO activity caused by TNBS to normal levels, Herbal acupuncture with Moxi-tar regulated $NF-{\kappa}B$ activity, which is an important factor for the pathogenesis of chronic colitis, and reduced the expressions of $TNF-{\alpha}$, $IL-1{\beta}$, and ICAM-1 in the colons of TNBS treated mice. Furthermore herbal acupuncture suppressed macro- and micro- colonic damages caused by TNBS. Conclusions : This study demonstrates that herbal acupuncture with Moxi-tar at BL25 isa potential preemptive and/or therapeutic method targeting the chronic IBD.

  • This study was performed to provide the optimal conditions of quantitative analysis for free amino acid in fermented protein foods. The water extractable free amino acid from dairy fermented foods was extracted effectively at $75^{\circ}C$ for 40 min., while it were extracted from fermented soy products at $40^{\circ}C$ for 3 hours. A close results of free amino acid content to those from amino acid analyzer were obtained using OPDA method with lysine standard after deproteinizing with 1% picric acid. 95% ethanol used as a deproteinizing reagent could give a comparable results to those from picric acid treatment in determining free amino acid content using OPDA method. Therefore, ethanol treatment was more recommendable than picric acid treatment which has some troubles in removing excess picric acid through Dowex resin column. The most desirable precipitation method for free amino acid determination using TNBS method was 95% ethanol treatment among the various deproteinizing procedure. The copper salt method was not suitable owing to its lacking reproducibility and pronounced discrepancy in determining free amino acid.
