  • We have previously demonstrated that overexpression and characterization of Brassica rapa type-l metallothionein gene (BrMT1) in Arabidopsis which showed enhanced resistance to cadmium and ROS. Here, we present the consistent study of our previous report about BrMTs. BrMT3 expressing DTY167 cells showed resistance to Zn and Pb as well as Cd. Thus, we have developed the BrMT3 overexpression Arabidopsis to enhance capacity for metal stresses. Successful expression and localization were achieved using the rubisco transit peptides of RbcS-BrMT3-GFP protein, which was confirmed by western blot analysis with the GFP antibody and green fluorescence signal from the chloroplast. BrMT3 overexpression Arabidopsis plants exhibited a higher resistance to cadmium compared to control plants. This result indicates that BrMT3 would be applicable to the development of plants with enhanced resistance against heavy metal stresses.

  • Typical susceptible symptoms of the bacterial pustule disease caused by Xanthomonas axonopodis pv. glycines are pustule and chlorotic haloes that usually occur in leaves of Glycine max plants. The soybean genotype 'PI96188' showed an atypical response to all tested races X. axonopodis pv. glycines, accompanied with necrosis without chlorotic haloes on the underside of the necrotic symptoms. X. axonopodis pv. glycines 8ra grew to levels from 10 to 100 fold lower on PI96188 than on susceptible cultivar Jinjoo1, but 10-fold higher than on the resistant cultivar CNS. The chlorophyll content in PI96188 leaves remained unchanged until 12 days after bacterial infection. Ultrastructural observation showed that the infected leaf cells of PI96188 had intact normal chloroplasts compared to those of the susceptible cultivar Jinjoo1. Chloroplast degradation or the absence of chloroplasts in cells of the infected tissues was observed in Jinjoo1. Senescence-related ACS7 gene was significantly induced in PI96188 compared to those in Jinjoo1 at 2 days after inoculation. While photosynthesis-related rbcS gene showed the dramatic change in Jinjoo1, this gene was constitutively expressed in PI96188. However, expression of the defense-related genes, such as peroxidase and isoflavone synthase in the infected PI96188 leaves was similar to that in Jinjoo1. Together, these results suggest that the novel necrotic symptom in PI96188 is a kind of resistant response different from a typical hypersensitive response in the resistant genotypes.

  • Formaldehyde (FA) is an economically important chemical, and has been found to cause various types of toxic damage to the body. Formaldehyde-induced toxic damage involves reactive oxygen species (ROS) that trigger subsequent toxic effects and inflammatory responses, which may increase risk of cancer. Therefore, in the present study, we aimed to investigate the possible toxic mechanism in bone marrow caused by formaldehyde. In accordance with the principle of randomization, the mice were divided into four groups of 6 mice per group. One group was exposed to ambient air and the other three groups were exposed to different concentrations of formaldehyde (20, 40, $80mg/m^3$) for 15 days in the respective inhalation chambers, 2h a day. At the end of the 15-day experimental period, all mice were killed. Bone marrow cells were obtained. Some of those were used for the determination of blood cell numbers, bone marrow karyote numbers, CFU-F, superoxide dismutase (SOD) activity and malondialdehyde (MDA) content; others were used for the determination of mitochondrial membrane potential (MMP), cell cycle and Bcl-2, Bax, CytC protein expression. WBC and PLT numbers in median and high dose groups were obvious reduced, but there was no change on RBC numbers. There was also reduced numbers of bone marrow karyotes and CFU-F in the high dose group. SOD activity was decreased, but MDA content was increased. MMP and Bcl-2 expression were decreased with increasing formaldehyde concentration, while expression of Bax and Cyt C was increased. We also observed change in cell cycling, and found that there was S phase arrest in the high dose group. Our study suggested that a certain concentration of formaldehyde could have toxic effects on the hematopoietic system, with oxidative stress as a critical effect.

  • Effects of dietary ${\delta}$-aminolevulinic acid (ALA) supplementation on serum iron status, blood characteristics, egg production and quality were examined in laying hens in an 8-week feeding trail. Two hundred and forty (Hy-line brown, 40-week-old) layers were randomly assigned to four dietary treatments with ten replications (six layers in adjacent three cages). Dietary treatments included: 1) CON (basal diet), 2) ALA1 (CON+ALA 5 ppm), 3) ALA2 (CON+ALA 10 ppm) and 4) ALA3 (CON+ALA 15 ppm). All nutrient levels of diets were formulated to meet or exceed NRC (1994) recommendations for laying hens. During the entire experimental period, differences of serum iron concentration and total iron binding capacity (TIBC) were significantly increased in ALA1 supplemented treatment (quadratic effect, p<0.05). The difference of total protein between 8 and 0 weeks was significantly higher in ALA2 treatment than CON treatment (quadratic effect, p<0.05). No significant effects were observed on hemoglobin, WBC, RBC, lymphocyte and albumin concentrations. Egg production and egg weight were not influenced by the ALA supplementation. Egg yolk index was also significantly higher in ALA3 treatment than CON treatment at the end of 4 and 8 weeks (linear effect, p<0.05). Haugh unit was increased in ALA3 treatment compared to CON and ALA1 treatments at the end of 8 weeks (linear effect, p<0.05). However, egg shell thickness, breaking strength and yolk color unit were not affected by the ALA supplementation. In conclusion, dietary ALA supplementation at a level of 5 ppm can affect iron concentration in serum while higher levels (10 or 15 ppm) have some beneficial influences on blood profiles and egg quality.

  • Rockfish, Sebastes schlegelii (mean length $14.53{\pm}1.14cm$ and mean weight $38.36{\pm}3.45g$), were exposed for 4 weeks with the different levels of ammonia in the concentrations of 0, 0.1, 0.5, and 1.0 mg/L at 19 and $24^{\circ}C$. The indicators of growth performance such as daily length gain, daily weight gain, condition factor, and hematosomatic index were significantly reduced by the ammonia exposure and high temperature. The ammonia exposure induced a significant decrease in hematological parameters, such as red blood cell (RBC) count, white blood cell (WBC) count, hemoglobin (Hb), and hematocrit (Ht), whose trend was more remarkable at $24^{\circ}C$. Mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) were also notably decreased by the ammonia exposure. Blood ammonia concentration was considerably increased by the ammonia concentration exposure. In the serum components, the glucose, glutamic oxalate transaminase (GOT), and glutamic pyruvate transaminase (GPT) were substantially increased by the ammonia exposure, whereas total protein was significantly decreased. But, the calcium and magnesium were not considerably changed.

  • I selected the theory of blood stasis and wetness-phlegm among the major 4 causes of Joong Poong(C.V.A.)(wind. fire. deficiency of vital energy and wetness-phlegm) and recent etiology of blood stasis. An experimental studies were done to investigate the effects of Danggieum (removing blood stasis and promoting blood circulation) and Ijintang(dissipating wetness-phlegm) on thrombosis and elevated blood viscosity. The results were as follows; 1. The number of platelets were significantly increased in only Danggieum group. 2. Related to the amount of fibrinogen. only Danggieum group revealed some increase. but both groups revealed no significance. 3. Related to the prothrombin time. Danggieum and Ijintang groups had significant decrease. but Danggieum group revealed more significance. 4. Related to the degree of concentration of FDP, only Danggieum group had significant decrease. 5. Whole blood viscosity and plasma viscosity in lower shear rates. both groups of Danggieum and Ijintang had significant decrease. 6. Related to the amount of RBC. both groups of Danggieum and Ijintang had significant decrease. 7. Related to the change of hematocrit. only Danggieum group, and the change of hemoglobin. only Ijintang group had significant decrease. 8. Related to the change of body temperature. only Ijintang group had significant raise. 9. Related to the changes of WBC. glucose, albumin, total protein and body weight. Danggieum and Ijintang groups had each increase or decrease. but no significance. According to the above results, Danggieum had more significant effect than Ijintang on the thrombosis. and Ijintang had more significant effect than Danggieum on the elevated blood viscosity. And it is considered that it might be more effective in treating Joong-Poong(C.V.A) to take medicines regarding patient's constitution and symptoms as well as the causes of Joong-Poong(C.V.A)

  • Gamrosu is a modified fasting therapy beverage (431 kcal/d). A retrospective observational study was conducted to investigate the detoxification feasibility of Gamrosu. Three cases were reviewed which participants have finished the fasting with Garmrosu for 10 consecutive days. Detoxification profiles of Gamrosu were reviewed at pre- and post-fasting sessions. Post-Gamrosu session, -6.3% of average weight, -6.5% of average body fat mass and -6.6% of average muscle mass were reduced with the nutrition indices being improved. The inflammation indices showed the significant diminished profiles. Liver/kidney functions and the standard of electrolytes were maintained within normal range in stable manners, however, marginal elevation of total bilirubin and mild ketoacidosis were observed. The indices of oxidative stress decreased and those of antioxidative activity increased. The fatigue scale scores indicated lower scores except insomnia symptom. Taken together, detoxification profiles of Gamrosu were sufficiently feasible and the observed findings should be considered for further clinical studies.

  • Juvenile Anoplopoma fimbria (mean length $15.6{\pm}1.4cm$, mean weight $68.7{\pm}4.3g$) were exposed to 4 months with the different levels of salinity [100 (35.0), 90 (31.5), 80 (28.0), 70 (24.5), 60 (21.0), 50 (17.5), and 40 (14.0) % (psu)] for 4 months. Hematological parameters such as red blood cell (RBC) counts, hematocrit (Ht), and hemoglobin (Hb) concentrations were substantially decreased under salinities of 50% psu or lower. Of the measured inorganic plasma constituents, magnesium was notably decreased, whereas there was no effect on calcium. Among organic plasma components, glucose and cholesterol were significantly increased, and total protein was decreased. Among enzyme plasma components, glutamic oxalate transaminase (GOT), glutamic pyruvate transaminase (GPT), and alkaline phosphatase (ALP) were significantly increased under salinities of 50% psu or lower. Antioxidant responses such as glutathione S-transferase (GST) and glutathione (GSH) were significantly decreased at salinities of 50% psu or lower. The results of this study indicate that salinity affects the blood parameters, plasma constituents, and antioxidant responses of A. fimbria.

  • Purpose : The Purpose of this research was to investigate the effects of Haingkyunghonghwatang (HKHHT) on anti-inflammatory effects. Methods : As for the parameters of inflammation, levels of several inflammatory cytokines and chemical mediators were determined in mouse lung fibroblast cells(mLFC) and RAW264.7 cells. Also, changes in pathological features by drug treatment were investigated in the in vivo edema-induced rats by carrageenin/arachidonic acid or in the colitis-induced mice by DSS treatment. Results : The cytotoxicity of HKHHT on mLFC and RAW264.7 cells wasn't observed at 100, 50, 10, and $1{\mu}g/ml$ of The treatments. $IL-1{\beta}$, IL-6 and NOS-II mRNA expression of RAW264.7 cells was inhibited by The treatments in a dose-dependent manner. HKHHT treatment of RAW264.7cells(HtRc) inhibited $TNF-{\alpha}$ and COX-2 mRNA expression. HtRc significantly inhibited IL-6 and NO production. HtRc inhibited ROS production. HKHHT inhibited rat's paw edema induced by carrageenin or arachidonate treatment in all concentrations examined. The body weight and colon length of colitis-induced mice were recovered to a normal level by DSS treatment. Clinical disease levels were significantly improved compared to the control animals. HKHHT treatment of colitis-induced mice(HtCm) significantly increased hematological values such as WBC and RBC counts, Hgb and HCT levels, but decreased PLT values. HtCm decreased IL-6 and $TNF-{\alpha}$ production significantly HtCm significantly increased CD3+(T) cell counts. In contrast, HKHHT treatment decreased CD19+ B cell counts and CD3+/CD69+ significantly, and also decreased B/T ratio (%) though not significant. Conclusion : These results indicated that HKHHT could be used for treating diverse female diseases caused by the inflammation.
