  • A system for the production of transgenic plants has been developed for Italian ryegrass(Lolium mult리orum Lam.) via Agrobacterium-mediated transformation of embryogenic callus. Mature seed-derived calli were infected and co-cultured with Agrobacterium EHA101 carrying standard binary vector pIG121Hm encoding the hygromycin phosphotransferase(HPT), neomycin phosphotransferase II (NPTII) and intron-oontaining $\beta$g1ucuronidase( intron-GUS) genes in the T-DNA region. The effects of several factors on transformation and the expression of the GUS gene were investigated. Inclusion of 200${\mu}M$ acetosyringone(AS) in inoculation and co-cultivation media lead to a significant increase in stable transformation efficiency. Increasing Agrobacterium cell density up to 1.0 in $OD_{600}$ during infection increased transfonnation efficiency of embryogenic calli. The highest transfonnation efficiency was obtained when embryogenic calli were incoulated with Agrobacterium in the presence of 0.1% Tween20 and 200${\mu}M$ AS. Hygromycin resistant calli were developed into complete plants via somatic embryogenesis. GUS histochemical assay and PCR analysis of transgenic plants demonstrated that transgenes were integrated into the genome of Italian ryegrass.

  • The objective of the current study was to determine the effects of the extracts isolated from the fruit body of Flammulina velutipes cultivated with oriental herbal plants on mouse splenocytes, B cells, and macrophages in vitro. The ethanol extracts B (EEB) directly induced the proliferation of spleen cells in a dose-dependent manner and increased IL-6, TNF-${\alpha}$, and IFN-${\gamma}$ synthesis. The EEB also increased the proliferation of B cells in a dose-dependent manner. The production of immunoglobulin M, G1, G2a, G2b, and IgG3 in the presence of the EEB increased progressively in the culture supernatant. When the EEB were used in macrophage cell line (RAW264.7) stimulation, there was a marked induction of NO synthesis in a dose-dependent manner and an increased IL-6, TNF-${\alpha}$, and GM-CSF synthesis. Intraperitoneal injection with EBB showed life prolongation effect of 16.1% in mice previously inoculated with sarcoma-180, respectively. These results suggest that the capacity of the EEB isolated from the fruit body of Flammulina velutipes cultivated with oriental herbal plants seems to act as a potent immunomodulator causing augmentation of immune cell activity, and with the absence of notable side-effects, Flammulina velutipes EEB could be used as a biological response modifier having possible therapeutic effects against immunological disorders. This study also showed that functional components of Flammulina velutipes were possibly improved by incorporating oriental herbal plants in a growth medium.

  • We have investigated the immunomodulatory activity of water extracts of Acanthopanax divaricatus var. alveofructus in male ICR mice. Mice were administrated with fermented milk containing freeze-dried extract 3 mg/Kg (A), 9 mg/kg (B), 27 mg/Kg (C) per body weight with A. divaricatus var. alveofructus (loots : leaves : stem) : Codonopsis lanceolata = (5 : 2 : 1.5) : 1.5 for 7 and 10 weeks, respectively. Body weight, relative organ weight, cellularity of lymphoid organs, plaque- forming cell (PFC) assay, agglutination (AGG) test and lymphoproliferation were examined in various groups of animals. Any significant differences of body weight gain were not recorded in the tested ICR mice. There was significant different (p<0.05) in the spleen index in B group of 10 weeks and C group of 7 weeks fed mouse. The thymus gain weight was increased during administration of the extract, but there was no significant increase on other organs gain. Humoral immunity as measured by PFC showed more decreased PFC level in 10 weeks than in 7 weeks. In the HT, A. divaricatus var. albeofructus extract also showed a significant increase (p<0.05) in C group of 10 weeks. Administration of extracts from A. divaricatus var. albeofructus increased significantly in the production of IgG antibodies on the mice immunized with SRBC in B group of 7 and 10 weeks (p<0.05).

  • Mastoparan V1 was used as adjuvant of formalin-inactivated Salmonella Gallinarum whole cells vaccine against fowl typhoid in a chicken model. The 75 brown nick chickens were equally divided into 5 groups, and all chickens of each group were immunized at 6 weeks of age (0 WPPI; weeks prime post immunization), and at 9 weeks of age (3 WPPI) (except group B). Group A chickens were intramuscularly (IM) inoculated with 500 uL of sterile phosphate-buffered saline (PBS), and group B chickens were subcutaneously immunized with 0.2 ml containing 5×107 viable vaccine strain/bird. The chickens in groups C~E were IM inoculated with approximately 3×109 cells/0.5 mL of formalin-inactivated the S. Gallinarum whole cells, approximately 3×109 cells/0.5 mL of formalin-inactivated the S. Gallinarum whole cells with mastoparan V1 as adjuvant, and 0.5 mL of PBS, respectively. S. Gallinarum outer membrane proteins-specific serum IgG titers were considerably higher in groups B~D than in groups A and E. However, the levels of IFN-γ in groups B and D only than in groups A and E were significantly higher. Following oral challenge with virulent wild-type S. Gallinarum, no chicken in groups A (no challenge group) and B was dead, and only 30% of chickens in group D was dead. However, 70% of chickens in group C and all chickens in group E were dead after oral challenge. The results of this study demonstrated that IM immunization with approximately 3×109 of the formalin-inactivated S. Gallinarum whole cells containing mastoparan V1 induced robust antibody and cell-mediated immune responses in chickens. The whole cells also conferred protection against infection with wild-type S. Gallinarum.

  • Objectives: Rehmannia glutinosa pharmacopuncture solution (RGPS) was investigated to determine both its anti-allergic inflammatory effects on mast cells and its detailed mechanism of actions. Methods: We investigated whether RGPS suppress cytokines, enzymes, $Fc{\varepsilon}RI$ expression and $Fc{\varepsilon}RI$-mediated signaling in RBL-2H3 cells stimulated with anti-DNP IgE/DNP-HSA. The suppressive effects of RGPS on the levels of cytokines such as IL-$1{\beta}$, IL-6 and GM-CSF were measured using emzyme-linked immunospecific assay (ELISA). The mRNA expression levels of cytokines, enzymes (HDC2, COX-1, COX-2 and 5LO) and $Fc{\varepsilon}RI$ ${\alpha}{\beta}{\gamma}$ subunits were measured using reverse transcription polymerase chain reaction (RT-PCR) method. The activation of $Fc{\varepsilon}RI$-mediated signaling was examined using Western blot analyses. Results: RGPS suppressed production of proinflammatory cytokines (IL-$1{\beta}$, IL-6, and GM-CSF) in stimulated RBL-2H3 cells significantly (p < 0.05). RGPS also suppressed mRNA expression of inflammatory enzymes (HDC2, COX-1, COX-2, 5LO). In addition, mRNA expression levels of $Fc{\varepsilon}RI{\alpha}$, $Fc{\varepsilon}RI{\beta}$and $Fc{\varepsilon}RI{\gamma}$ were lowered by treatment with RGPS. Finally, RGPS prevented phosphrylation of Lyn, Syk, LAT, Gab2, PLC ${\gamma}1/2$, PI3K, Akt, cPLA2 and $I{\kappa}B{\alpha}$. Conclusions: RGPS effectively suppresses mast cell activations such as degranulation and inflammatory response via down-regulation of the $Fc{\varepsilon}RI$-mediated signaling pathways in IgE/Ag-stimulated mast cells.

  • In order to investigate the efficacy of HYGBH on atopic dermatitis, various immune related factors were studied. The results and conclusions are as follows. Atopic dermatitis symptoms were improved in HYGBH treated group and significant decrease in dermatitis index were observed in 12 and 14 weeks. HYGBH treated group showed significant decrease in CD4+, CD3+/CD69+ immune cell ratio in PBMC by 18% and 40.6% respectively. HYGBH treated group showed significant decrease in CD3+, CD11b+/Gr-1+ immune cell ratio in dorsal skin by 44.6% and 53.1% respectively. HYGBH treated group showed significant decrease in IL-4, IFN-${\gamma}$ in spleen by 29.5%, 7.7% respectively. HYGBH treated group showed decrease in the expression of IL-5, IL-13, IL-17 and histamine by 21%, 9.6%, 14%, and 32.2% respectively. Also the group showed decrease in the expression of IgE by 6.8% respectively. HYGBH treated group showed significant decrease in the transcription of IL-5 and IL-3 mRNA in skin by 35.5% and 23.2% respectively. The results above indicated that treatment of HYGBH improved atopic dermatitis symptoms by anti-oxidant activity as well as immune modulation activity as a clinical evidence. Also, to increase the application of fermented oriental medicine, different fermentation conditions using various microbial strains should be accumulated as the clinical evidence in the future.

  • Atopic dermatitis (AD) is a common skin disease characterized by chronic and relapsing inflammatory dermatitis with immunological disturbances. Spleen deficiency (脾虛) is one of the major causes of AD, so development of animal model is required for AD research that reflects the pattern identification. The groups that we have used in this study included Senna folium extracts (SFE), 2,4-dinitrochlorobenzene (DNCB), and normal mice. Therefore, the present study was developed to atopic dermatitis mouse model with spleen deficiency in 2,4-dinitrochlorobenzene (DNCB) and senna leaves extracts induced AD in NC/Nga mice. The results demonstrated that senna leaves extract treatment significantly increased the dermatitis clinical score and epidermal thickness in AD-like skin lesions. We also proved beyond doubt that there was occurrence of erythema and skin moisture indices in the senna leaves extract groups. Further, we also found that the level of serum immunoglobulin E (IgE) in the senna leaves extract-treated group was increased. The amount of IL-4, IL-13, $TNF-{\alpha}$ and $TGF-{\beta}$ mRNA determined by real-time PCR was increased remarkably when senna leaves extract groups were treated on dorsal skin. Senna leaves extract groups significantly promoted the number of CD11B+/Gr-1 cell in skin, as well as the number of CD4+/CD8+ cell in dorsal skin compared with control. The review summarizes recent process in our understanding of the immunopathophysiology of spleen deficiency AD and the implications for spleen deficiency mouse models of AD on drug discovery from medical plants.

  • This study was conducted to determine effects of fermented brown seaweed waste (FBSW) on milk production, composition and physiological responses as functional feed for 60 days in Holstein dairy cows. A total of 24 Holstein dairy cows (average age 49.33 months, average lactation days 175, Reproduction 2.0) were randomly allocated into control(basal diet), 1% FBSW (180g in basal diet) and 2% FBSW (360g in basal diet) groups with 8 replications for 60 days. Daily milk yield and composition (fat, protein, SNF, MUN) were not affected by FBSW supplementation, but Ca level in milk was significantly increased 4.29 mg/dl and 2.91 mg/dl in 1% and 2% groups compared to control group (p<0.05) at the end of the experiment, respectively. The somatic cell count (SCC) in milk was not significant. The plasma $T_4$ level (concentration) were increased in 1% and 2% FBSW compared to control group at the end of the experiment (p<0.05), but between triiodothyronine ($T_3$) and thyroxin ($T_4$) levels were not significant. Concentrations of plasma glucose in control, 1% FBSW and 2% FBSW groups were 64. 37mg/dl, 66.15mg/dl and 73.02 mg/dl and plasma NEFA level was 0.30~0.32 mEq/dl. Concentrations of BUN tended to be higher for FBSW group than control group. Although WBC, RBC, Hb, Hct, T-B, ALP, and GPT levels were not affected by FBSW supplementation, GOT level was significantly decreased in cows fed 1% FBSE diet compared to control group (P<0.05). Therefore we strongly suggest that the 1% FBSW supplementation in basal diet increases the milk yield and Ca level in Holstein dairy cows.

  • Few observation have been made on the pericardial pressure and little is known about the composition of he pericardial fluid. So we studied the basic qualitative and quantitative analysis of the pericardial fluid in the patients with cardiac disease either congenital heart diasese(group A) or acquired heart disease(group B). The pressure of the pericardial cavity was measured by the method of open tipped water filled small polyethylene catheter connecting to the standardized monitor, which was introduced into pericardium of the patients who were performed pericardial incision for the heart or pericardial surgery. All of the data was compared to the simultaneously checked hematologic value of the same patient. The mean pressure of the pericardial cavity was 2.4mmHg and the amount of the pericardial fluid was 13cc/m2 of body surface for the group A and 17.7cc for the group B. And the cell count was 138$\pm$l16/1 in group A and 230$\pm$135/1 in group B and the pH was 7.83$\pm$0.40 in group A. 7.80$\pm$0.52 in group B. Pericardial fluid revealed satisfactically significant alkaline pH than plasma. The fundamental electrolyte, Wa+, K+, Cl and glucose were identical to the hematologic values of the same patient, but the protein concentration was 2.Bg/dL for group A and 3.Ig/dL for group B heart disease and those were remarkable low concentration compared to the hematologic value of the same patient. LDH and amylase were identical to the value of the serum of the same patient, but the concentration of LDH of group B was slightly higher than that of the group A.

  • Correlation between vaccine reactogenicity and immunogenicity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is unclear. Thus, we investigated to determine whether the reactogenicity after coronavirus disease 2019 vaccination is associated with antibody (Ab) titers and T cell responses. This study was prospective cohort study done with 131 healthcare workers at tertiary center in Seoul, South Korea. The degrees of the local reactions after the 1st and 2nd doses of ChAdOx1 nCov-19 (ChAdOx1) vaccination were significantly associated with the S1-specific IgG Ab titers (p=0.003 and 0.01, respectively) and neutralizing Ab (p=0.04 and 0.10, respectively) in age- and sex-adjusted multivariate analysis, whereas those after the BNT162b2 vaccination did not show significant associations. T cell responses did not show significant associations with the degree of reactogenicity after the ChAdOx1 vaccination or the BNT162b2 vaccination. Thus, high degree of local reactogenicity after the ChAdOx1 vaccine may be used as an indicator of strong humoral immune responses against SARS-CoV-2.
