  • Objective : Several studies hove suggested that reduction of cholesterol concentration and low cholesterol level increases suicide, homicide, and depression. The authors sought to determine whether low cholesterol is associated with a history of suicidal attempts among major depression patients. Method : The subjects were 105 patients with major depression, diagnosed according to the DSM-III-R criteria, and 105 age, sex matched healthy controls. Blood was token following overnight fast and serum cholesterol concentration were measured by a enzymatic method Results : The serum cholesterol level was significantly lower in the patients with major depression than in healthy controls($180.4{\pm}43.4mg/dl$ vs $199.7{\pm}35.8mg/dl$). And the serum cholesterol level was significantly lower in major depression patients with suicidal attempt than in major depression patients without suicidal attempt($156.7{\pm}38.2mg/dl$ vs $ 187.8{\pm}42.5mg/dl$) Conclusion : It is hypothesized that low cholesterol level is associated with depression by modifying the serotonin metabolism and the production of interleukin-2, low cholesterol concentration should be further investigated as a potential biological marker of suicidal risk in major depression. Prospective study with serial cholesterol determinations should be done.

  • Anglicae dahuricae Radix (ADR), the dried roots of Angelica Dahurica Benth et Hook (Umbelliferae), is a traditional herbal medicine used to treat colds, headache, skin diseases such as acne and possess analgesic, antipyretic and drainage effects. In the present study, the author evaluated the effect of ADR on regulation of inflammatory reaction. ADR reduced the ear-swelling responses derived from compound 48/80 in dose-dependent manner significantly. ADR inhibited the PMA plus A23187-induced productions of IL (Interleukin)-8, IL-1β, granulocyte macrophage-colony stimulating factor (GM-CSF) and tumor necrosis factor (TNF)-α from human mast cells (HMC)-1. In addition, ADR blocked PMA plus A23187-induced ERK1/2 phosphorylation. Ⅰ suggest that ADR regulates inflammatory reaction through inhibition of inflammatory cytokines such as IL-8, IL-1β and GM-CSF.

  • BACKGROUND/OBJECTIVES: Carnosic acid (CA), found in rosemary (Rosemarinus officinalis) leaves, is known to exhibit anti-obesity and anti-inflammatory activities. However, whether its anti-inflammatory potency can contribute to the amelioration of obesity has not been elucidated. The aim of the current study was to investigate the effect of CA on Toll-like receptor 4 (TLR4) pathways in the presence of lipopolysaccharide (LPS) in 3T3-L1 adipocytes. MATERIALS/METHODS: 3T3-L1 adipocytes were treated with CA ($0-20{\mu}M$) for 1 h, followed by treatment with LPS for 30 min; mRNA expression of adipokines and protein expression of TLR4-related molecules were then measured. RESULTS: LPS-stimulated 3T3-L1 adipocytes showed elevated mRNA expression of tumor necrosis factor (TNF)-${\alpha}$, interleukin-6, and monocyte chemoattractant protein-1, and CA significantly inhibited the expression of these adipokine genes. LPS-induced up regulation of TLR4, myeloid differentiation factor 88, TNF receptor-associated factor 6, and nuclear factor-${\kappa}B$, as well as phosphorylated extracellular receptor-activated kinase were also suppressed by pre-treatment of 3T3-L1 adipocytes with CA. CONCLUSIONS: Results of this study suggest that CA directly inhibits TLR4-MyD88-dependent signaling pathways and decreases the inflammatory response in adipocytes.

  • Ginsan is an acidic polysaccharide purified from Panax ginseng, a famous oriental herb. Although a variety of biological activities of ginsan have been studied, the effects of ginsan on spleen cells are not fully elucidated. We investigated the effect of ginsan on the viability and proliferation of spleen cells. Using Cell Counting $Kit-8^{(R)}$ solution and trypan blue solution, we found that ginsan significantly enhanced viability and proliferation. Multiple clusters, indicating proliferation, were observed in ginsan-treated spleen cells and, carboxyfluorescein succinimidyl ester and surface marker staining assay revealed that ginsan promoted proliferation from $CD19^+$ B cells rather than $CD4^+$ or $CD8^+$ T cells. In addition, ginsan decreased the percentage of late apoptotic cells. Ginsan increased the surface expression of CD25 and CD69 as well as production of interleukin-2 from spleen cells, suggesting increased activation. Taken together, these results demonstrate that ginsan increases the viability and proliferation of spleen cells via multiple mechanisms, valuable information for broadening the use of ginsan in clinical and research settings.

  • 'SecSec' has been used for the purpose of prevention and treatment of throat diseases such as sore throat, cough, bronchial asthma and allergic asthma in Korea. However, its effect in experimental models remains unknown. To investigate the biological effect of SecSec, we examined cytotoxicity and secretion of inflammatory cytokines on human leukemic mast cell line, HMC-1, stimulated with phorbol 12-myristate 13-acetate (PMA) and calcium ionophore A23187. SecSec by itself had no cytotoxicity on HMC-1. When SecSec (1 mg/ml) was added, the secretion of tumor necrosis factor-alpha $(TNF-{\alpha})$, interleukin (IL)-6, and granulocyte macrophage-colony stimulating factor (GM-CSF) was significantly inhibited about 47.20%, 25.55%, and 46.43%, respectively on PMA plus A23187-stimulated HMC-1 cells. But SecSec did not inhibit IL-8 secretion. These findings may help understanding the mechanism of action of this medicine leading to control activated mast cells on allergic inflammatory condition like asthma.

  • Objectives: Angelicae Dahuricae Radix (Baek-Ji in Korean, BJ) is well known to be used as a medicine for cold, headache, supraorbital pain, nasal congestion, and toothache. Little is understood about the roles of BJ in the cytokine and chemokine secretion by immune cells. This study was designed to find out the effects of BJ on the cytokine and chemokine secretion in human mast cells (HMC). Methods : We treated BJ according to consistency on HMC and measured cytokines and chemokines levels using flow cytometry CBA system. Results: In BJ treated group. the expression of interferon-inducible protein 10 (IP-l0), monocyte chemoattractant protein-1 (MCP-1), chemokine (C-X-C motif) ligand 9 (MIG), and interleukin 10 (IL-l0) levels were decreased significantly and chemokine (C-C motif) ligand 5 (RANTES), IL-8, $interferone-{\gamma}$ ($IFN-{\gamma}$), and tumor necrosis factor alpha (TNF-a) were decreased significantly. Conclusion : The results of this experiment supposed that the treatment of BJ will ameliorate the secreting levels of some chemokines or cytokines such as IP-10, MCP-1, MIG, IL-10, RANTES, IL-8, $IFN-{\gamma}$, and TNF-a.

  • In our study, the several cytokines were determined in phytohaemagglutinin (PHA)-stimulated peripheral blood mononuclear cells (PBMC) of Adamantiades-Behcets patients. Adamantiades-Behcets disease (ABD) is a systemic inflammatory disorder and might involve immune dysfunction. High levels of $TNF-\alpha,\;IL-1\beta$ and $IFN-{\gamma}$ indicate the activation of inflammatory reactions and immune system in ABD. Gami-Phedoc-San (GPS) is an Oriental herbal medication, which has been used in Korea for the treatment of ABD. GPS (1 mg/ ml) significantly inhibited the secretion of proinflammatory cytokines, $TNF-\alpha\;and\;IL-1\beta$, compared to absence of GPS (by $50.5{\pm}1.9%$ inhibition for $TNF-\alpha$ and $106.9{\pm}16.8%$ for $IL-1\beta$). GPS also inhibited the production of $IFN-\gamma$, immunoregulatory Th1 cytokine, by $78.4{\pm}2.8%$. The inhibitory effects of GPS on cytokine secretion showed dose-dependent manner, and the pre-treatment of 1 mg/ml GPS had better effects than immunosuppressive drug for treatment of ABD, cyclosporin A. Our results suggest that GPS treatment for ABD patients might have pharmacological activity of immune and inflammatory responses through the cytokine modulation.

  • Ikwi-tang (IW) is an oriental medicine that has been used for the treatment of general symptoms due to a stomach yin deficiency. The aim of this study is to investigate precisely the effect of IW on allergic rhinitis (AR). We well show the effects and the mechanism of IW in the ovalbumin-sensitized AR model. IW significantly decreased the number of nasal/ear rubs and the increment of IgE levels in the AR mice. The levels of interferon-${\gamma}$ were enhanced while the levels of interleukin (IL)-4 were reduced in the spleen tissue of the IW-administered AR mice. Expressions of IL-$1{\beta}$ and cyclooxygenase-2 were inhibited by IW-administration in the nasal mucosa tissues. Infiltration of eosinophils and mast cells was decreased in the IW-administered AR mice. Our results indicate that IW may attenuate the development of AR by the inhibition of caspase-1 activity.

  • Adenophorae Radix (AR) has been used as a traditional medicine for various diseases. However, the regulatory mechanisms of AR in allergic inflammation are not yet understood. The present study was conducted to investigate the effect and mechanisms of AR on the mast cell-mediated allergic response. To determine the pharmacological mechanisms of AR in allergic inflammation, we evaluated the effects of AR on the production of tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-1β and IL-8 as well as the activation of nuclear factor-κB (NF-κB) and caspase-1 in phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated human mast cells (HMC-1). Our results demonstrated that AR effectively attenuated the PMACI-induced production of TNF-α, IL-6, IL-1β and IL-8 in stimulated HMC-1. Additionally, we showed that the inhibitory effect of AR on inflammatory cytokines in PMACI-stimulated HMC-1 cells involved the suppression of the activation NF-kB/caspase-1 in PMACI-stimulated HMC-1. Collectively, these findings provide experimental evidence that AR may be a useful candidate for the treatment of allergic inflammation.
