  • The present study was performed to assess the worth of using the by products for seaweed (Eucheuma spinosum) ethanol production process (SEPPB) as broiler feeds. For this purpose, 225 broiler chicks (white mini broilers) were used as experimental animals. The control (Control group) was fed with the broiler feeds. 5% mixture (5% SEPPB group) was fed with a 5% SEPPB mixture feeds, and the 10% mixture (10% SEPPB group) was fed with a 10% SEPPB group mixture feeds. The experiment was repeated for five times and 15 birds were assigned in each experiment and the experimental period was five weeks. There was no difference in the rate of weight gain until the second week of the 5% SEPPB group and 10% SEPPB group. However, the weight gain rate was increased to 6.2% for the 5% SEPPB group and 11.4% for the 10% SEPPB group as compared to the Control group at the third weeks of the experimental period. There was no statistical significant difference in terms of feed FCR and feed intake. Analyses of the quality of chicken breasts showed that pH was 2.5% higher in the 5% SEPPB group and 2.3% higher in the 10% SEPPB group. Shearing force was 31.3% lower in the 5% SEPPB group and 14.7% lower in the 10% SEPPB group, while heating loss was 14.4% lower for 5% SEPPB group and 10% SEPPB group when compared to the Control group. No significant differences were observed in terms of moisture, protein, and crude ash components in chicken breast analyses. However, crude fat was 36.8% higher in the 5% SEPPB group when compared to the Control group (P<0.05). Analyses of fatty acid in chicken breast meat showed that stearic acid was significantly higher in the 10% SEPPB group (P<0.05) and linolenic acid was significantly higher in 5% SEPPB group and 10% SEPPB group in comparison to the Control group (P<0.05). Interleukin-2 (IL-2) in blood serum was 44% higher in the 5% SEPPB group and 36% higher in the 10% SEPPB group (P<0.05). Interleukin-6 (IL-6) was similar in both the Control and the 5% SEPPB group, but it was 62% higher in the 10% SEPPB group in comparison to the Control group (P<0.05). Analyses of serum chemical values revealed that albumin was the highest in the 5% SEPPB group, followed by the Control group and then 10% SEPPB group.

  • The TH cytokine responses of spleen cells stimulated with Con A from mice infected with Polasonimw westemcni were examined. The spleen cell culture supema- tants were assayed for TH1-specific $IFN-{\gamma}$ and TH2-specific IL-4. Cytokine responses for IL-4 peaked at three days ($410{\;}{\pm}{\;}60.9{\;}pg/ml$), persisted at a high level until the second week ($343{\;}{\pm}{\;}59.0{\;}pg/ml$), and then decreased slowly four and six weeks after infection. $IFN-{\gamma}$ production by splenocytes only increased during the first week ($151{\;}{\pm}{\;}32.3{\;}pg/ml$) and declined abruptly after the second week of infection. IFN- y production by splenocytes of infected mice was not observed during the sixth week of infection. In addition, serum IL-4 and $IFN-{\gamma}$ were measured. Serum IL-4 was not detected in substantial quantity until four to six weeks after infection. The time course of serum IL-4 was not correlated with that of IL-4 production by splenocytes. Serum $IFN-{\gamma}$ was undetectable during the entire course of infection. These results suggest that TH2 cytokine responses, rather than TH1, predominate in mice infected with P. westemcni.

  • Lactoferrin is an iron-binding glycoprotein which is present in colostrum, milk, and other body secretions. Lactoferrin activities are associated with inflammatory and immune responses. The aim of this study was to investigate the effect of lactoferrin hydrolysates (LH) on the production of immunomodulatory factors such as inflammatory related cytokines (tumor necrosis factor $(TNF)-{\alpha}$, interleukin $(IL)-1{\beta}$, interleukin (IL)-6, and interleukin (IL)-13) in Raw264.7 cells, which originated from murine macrophages. The results show that the Raw264.7 cells cultured in 3 types (whole, and above and below 10 kDa) of lactoferrin hydrolysates (LH) did not show any cytotoxicity in the cells. $TNF-{\alpha}$ decreased dose-dependently to 1,500 - 2,000 ng/mL by treatment with the 3 types of LH at 1, 50, $100{\mu}g/mL$, whereas the positive control, lipopolysaccharide (LPS), and negative control produced 2,450 and 1,000 ng/mL of $TNF-{\alpha}$, respectively, in the Raw264.7 cells. The treatment with the 3 types of LH (whole and above and below 10 kDa) at $50{\mu}g/mL$ produced about 20 - 28 ng/mL of $IL-1{\beta}$ at 3, 6, and 9 h, respectively, while the negative control produced 7 ng/mL, and LPS as the positive control produced 48 - 60 ng/mL. $TNF-{\alpha}$ and IL-6 expression was decreased dose-dependently by the 3 types of LH. The mRNA levels of IL-13 were slightly increased dose-dependently by the whole and above 10 kDa LH, but decreased dose-dependently by the below 10 kDa LH in the Raw264.7 cells. The results show that LH had immunomodulating effects on cytokine production in anti- and pro-inflammatory reactions as well as anti-allergic reactions.

  • Seborrheic dermatitis (SD) is the skin disease occurred because of Malassezia yeast which grows on the skin and scalp, and this yeast lives on sebum lipid, and their metabolite, free lipid acids are thought to be the main irritant on skin. To find out effective cosmeceutical ingredients to treat SD symptoms, we established novel cell-based in vitro model mimicking SD symptoms. This in vitro model adopted the co-culture system with primary sebocyte & HaCaT keratinocyte. We used M. globosa yeast extract, arachidonic acid, linoleic acid and dihydrotestosterone as SD inducers. In the co-culture system with optimized concentrations for SD-inducing cocktail, the production of IL-8 and sebum lipids increased up to 2-fold, and then we screened with commercial essential oils by monitoring IL-8 as a key inflammatory biomarker. Then we found that Cinnamomum zeylanicum oil, Mentha arvensis oil effectively down-regulated IL-$1{\alpha}$, IL-6, IL-8 cytokines which over-produced by SD-inducing cocktail. Additionally, two essential oils also showed inhibitory effect on sebum lipid synthesis from primary sebocyte and growth inhibitory effect to M. globosa yeast (MICs were lower than 0.0625 %). Our recent results suggest that Cinnamomum zeylanicum oil and Mentha arvensis oil could be effective natural herbal remedies to relieve or protect scalp seborrheic dermatitis.

  • Medicinal herbs have long been used as a remedy for diverse diseases in Asia owing to their various pharmacological effect. In this study, the immuno-enhancing activity of medicinal herbs was investigated using macrophage cell lines. Specifically, we examined the effects of extracts of twelve medicinal herbs on nitric oxide (NO) production in RAW 264.7 cells, and selected five that were highly effective (Glycyrrhiza glabra, Rehmannia glutinosa, Angelica gigas, Platycodon grandflorum, and Actinidia polygama) for further immune related studies. The effects of extracts from five theses medicinal herbs, which were mainly composed of polysaccharides and proteins on the production of immune-related cytokines in the RAW 264.7 macrophage cell line and the Molt-4 T cell line were investigated. The extracts of all investigated medicinal herbs increased the production of NO and cytokines such as tumor necrosis factor-alpha (TNF-${\alpha}$), interleukin-1beta (IL-$1{\beta}$), interleukin-6 (IL-6) and interleukin-10 (IL-10). Additionally, they slightly increased the proliferation of T-cells when compared to the control. Overall, the result of this study suggests that the five medicinal herb extracts investigated herein are useful natural immune enhancing agents.

  • In this study, the immuno-enhancing activity of seed extracts were studied on the macrophage cell lines. We examined the effect of nine seed extracts on nitric oxide (NO) production in RAW 264.7 cells and selected four highly-effective seed candidates (Fagopyrum esculentum, Taraxacum platycarpum, Impatiens balsamina, Helianthus annuus) for further immune-related studies. The effects of the four seed extracts on the production of immune-related cytokines in the RAW 264.7 macrophage cell line and proliferation of Molt-4 as a T cell line were investigated. The secretion of NO from the RAW 264.7 cells was increased up to 39 ${\mu}M$ by adding the seed extracts (25 ${\mu}g/mL$) compared to the control. Also, the secretion of tumor necrosis factor-alpha (TNF-${\alpha}$) was also increased up to 32 times by adding the seed extracts (25 ${\mu}g/mL$). Secretion of cytokines such as interleukin-1 beta (IL-$1{\beta}$), interleukin-6 (IL-6), and interleukin-10 (IL-10) was also increased and induced the proliferation of T cells compared to the control. In conclusion, these results suggest that four seed extracts provide beneficial immuno-enhancing effects for human health.

  • Objectives Angiotensin-converting enzyme (ACE) gene and plasma levels of cytokines, such as tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$), interleukin-4 (IL-4), interleukin-6 (IL-6), interleukin-10 (IL-10), have previously been determined to be associated with depression. The purpose of this study was to investigate the association of plasma levels of ACE and cytokines with recurrent depression. Methods A total of 52 participants (14 male, 38 female, aged $43.9{\pm}14.0years$) were enrolled after being diagnosed with depression by experienced psychiatrists using the Mini International Neuropsychiatric Interview from the outpatient clinic of the Department of Psychiatry, CHA Bundang Medical Center. The participants completed blood sampling, the Hamilton Depression Rating Scale (HAMD), the Beck Depression Inventory, the Beck Anxiety Inventory, and the Scale for Suicidal Ideation. Results ACE plasma levels are higher in patients with recurrent depression ($27.4{\pm}10.4U/L$) than in patients with newly diagnosed depression ($19.1{\pm}7.7U/L$) (p = 0.004). The levels of cytokines, such as $TNF-{\alpha}$, IL-4, IL-6, IL-10, are not significantly different between the two groups. Additionally, the ACE plasma level is negatively correlated with a reduction in the HAMD over six weeks (r = -0.429, p = 0.046, n = 22). Conclusions The current findings show that plasma ACE levels may be associated with recurrent depression and further suggest that the renin-angiotensin system could play a role in recurrent depression.

  • 목적 - Inflammatory cytokine으로 알려진 interleukin 1$\beta$, tumor necrosis factor $\alpha$는 치수 및 치근단질환에서 주요한 역할을 하며, 골흡수를 자극하고 골형성을 방해하는 것으로 알려져 왔다. 이들 cytokine은 주로 단핵세포/대식세포가 형성하는 것으로 알려져 왔으나 최근 연구에 의하면, PMN도 또한 이 런 cytokine들을 형성할 수 있다는 것이 보고되었다. 오랫동안 염증반응이나 면역반응에서 PMN의 역할이 주로 포식작용 을 통해 병원균을 제거하는 것이라고만 생각되어져 왔던 것을 생각하면, 새로운 발견이라 할 수 있다. 또, PMN은 IL-1ra도 생성하는 것으로 보고되었는데, IL-1ra란 IL-1의 생물학적 작용을 방해하는 인자이므로, IL-1과 밀접한 관련을 가지는 질환의 발전에 있어서 IL-1과 IL-1ra의 balance가 매우 중요한 역할을 할 것으로 생각된다 즉, IL-1ra는 IL-1$\beta$의 proinflammatory effect를 제한할 수 있는 negative feedback mechanism이라고 할 수 있다. 이 연구의 목적은 치수 및 치근단 조직의 감염에 있어서 주요 원인균인 Porphyromonas endodontalis의 LPS가 PMN의 IL-1$\beta$, TNF-$\alpha$, IL-1ra생성에 미치는 영향을 단백질과 mRNA 수준에서 관찰하는 것이다. 잘 알려진 non-oral bacterium인 E. coli의 LPS를 positive control로 사용하였으며, IL-1ra가 IL-1$\beta$의 생물학적 작용을 방해하는 작용을 관찰하기 위해, IL-1의 biological assay도 시행하였다. 방법 - P. endodontalis ATCC 35406을 혐기성 조건에서 배양하고, hot phenol-water extraction의 방법으로 LPS를 추출(crude LPS)한 후, 제조회사로부터 구입한 E. coli의 crude LPS와 함께 정제하였다. 건강한 자원자들을 대상으로 말초혈액을 채취한 후 dextran sedimentaion을 거쳐 Lymphoprep을 이용하여 PMN층을 분리하였다. 얻어진 세포들은 RPMI 1640 (supplemented with fetal bovine serum antibiotics)에 5$\times$$10^{6}$cells/ml이 되도록 resuspend시킨 후 각기 다른 농도 (0, 0.01, 0.1, 1 and 10$\mu$g/ml)의 LPS를 처리하여, 각기 다른 시간(Northern blot : 1, 2, 4시간 ELISA : 2, 6, 12, 18시간)동안 37$^{\circ}C$ in 5% $CO_2$ 의 조건으로 배양하였다. 상층액은 -7$0^{\circ}C$에 보관하였다가 추후에 ELISA를 이용한 단백질 농도 측정과 IL-1 biological assay에 사용되어졌으며, 배양된 세포로부터 RNA를 추출하여 Northern hybridization을 통해 mRNA expression을 관찰하였다.
