The purpose of this research was to investigate the effects of Seungyangikkitang (SIT) on the immune cells in BALB/c mice. SIT (500mg/kg) was administerd p.o. once a day for 7 days. SIT enhanced the proliferation of thymocytes, but decreased the proliferation of splenocytes. SIT enhanced the subpopulation of cytotoxic T cells in thymocytes and helper T cells in splenocytes, but did not affect the subpopulation of B220/Thy1 cells. SIT enhanced the production of γ-interferon and interleukin-2 in thymocytes, splenocytes and serum, but did not affect the production of interleukin-4. SIT suppressed the production of nitric oxide, but enhanced the lucigenin chemiluminescence and the engulfment of FITC-conjugated E. coli particles in peritoneal macrophages. These results suggest that SIT has a potent activity on the specific immunity via the cytokine secretion of Th1 cells and the non-specific immunity via the phagocytic activity of macrophages in vivo.

패혈증은 병원성 감염에 의해 여러 장기에 나타나는 전신성 염증 반응으로, 현재로서는 유망한 치료제가 없다. Signal transducer and activator of transcription 3 (STAT3)은 세포 신호전달 전사 인자로서 항염증 및 염증 반응과 관련된 다양한 세포의 생물학적 과정에서 중요한 역할을 한다. Niclosamide는 FDA에서 승인된 구충제로 STAT3 조절에 관여한다고 알려져 있다. C57BL/6 마우스에 복강 주사로 지질 다당체 (lipopolysaccharide, LPS)를 투여해 패혈증을 유발하였고, Niclosamide를 LPS 주사 2시간 후에 경구 투여하였다. 본 연구에서 Niclosamide가 LPS로 유발된 패혈증 모델의 생존률과 폐 손상을 완화시켰고, 혈청 내 interleukin (IL)-6, 종양괴사인자(tumor necrosis factor-α, TNF-α), IL-1β, AST, ALT, LDH 수치를 유의하게 감소시켰다. 또한 폐 조직 면역 블롯을 통해 PI3K, AKT, NF-κB, STAT3 신호 전달 경로가 Niclosamide에 의해 조절되는 것을 확인하였다. Niclosamide는 LPS를 자극한 RAW 264.7 세포주에서 IL-6, TNF-α, IL-1β와 같은 염증성 사이토카인의 발현을 감소시켰으며, 또한 STAT3의 인산화를 감소시켰다. 본 연구를 통해 Niclosamide에 의한 STAT3 조절이 염증 반응을 억제함으로써 패혈증 모델에 대한 새로운 치료 전략을 제시하였다.

This experimental study was carried out to evaluate the effects of Acanthopanacis cortex on Cytokine-inducing and and immune response in Mice. In order to investigate the effect of Acanthopanacis cortex, the following was performed; Cytotoxicity, in vitro, the fraction of $CD4^+$, $CD8^+$, $B220^+$ in splenic cell, gene expression of IL-12(p35), IL-12(p40), IFN-${\gamma}$, and splenic cell proliferation by Acanthopanacis cortex. Analysis of cytokine gene expression was carried out by RT-PCR amplification. Amplified PCR products were electrophoresed on 1.2% agarose gel, and the analysis (Ht) was used to 1D-density program. The results were obtained as follows. Acanthpanacis cortex showed didn't have cell toxicity under $12{\mu}g/m{\ell}$ group on mouse lung fibroblast cells. In an in vitro model using mouse peripheral blood mononuclear cells (PBMCs), extract of Acanthpanacis cortex induced multiple cytokine, including interleukin-12 (p35), interleukin-12 (p40), interferon-gamma (IFN-${\gamma}$). The extract also enhanced the percentages of the $CD4^+$, and $CD8^+$ in the untreated control were $22.1{\pm}3.3$ to $38.4{\pm}2.1$, and $5.0{\pm}0.4$ to $10.7{\pm}0.3%$, respectively. From above findings, it is suggested that Acanthopanacis cortex is able to anti-cancer and activate immune response system.

[Purpose] Strenuous exercise often induces skeletal muscle damage, which results in impaired performance. Sphingolipid metabolism contributes to various cellular processes, including apoptosis, stress response, and inflammation. However, the relationship between exercise-induced muscle damage and ceramide (a key component of sphingolipid metabolism), is rarely studied. The present study aimed to explore the regulatory role of sphingolipid metabolism in exercise-induced muscle damage. [Methods] Mice were subjected to strenuous exercise by treadmill running with gradual increase in intensity. The blood and gastrocnemius muscles (white and red portion) were collected immediately after and 24 h post exercise. For 3 days, imipramine was intraperitoneally injected 1 h prior to treadmill running. [Results] Interleukin 6 (IL-6) and serum creatine kinase (CK) levels were enhanced immediately after and 24 h post exercise (relative to those of resting), respectively. Acidic sphingomyelinase (A-SMase) protein expression in gastrocnemius muscles was significantly augmented by exercise, unlike, serine palmitoyltransferase-1 (SPT-1) and neutral sphingomyelinase (N-SMase) expressions. Furthermore, imipramine (a selective A-SMase inhibitor) treatment reduced the exercise-induced CK and IL-6 elevations, along with a decrease in cleaved caspase-3 (Cas-3) of gastrocnemius muscles. [Conclusion] We found the crucial role of A-SMase in exercise-induced muscle damage.

닭의 전염성 F낭병 바이러스(IBDV)가 원인 바이러스인 전염성 F낭병은 전 세계 양계산업에 경제적으로 피해가 큰 중요한 질병이다. 이 연구의 목적은 닭에서 IBDV에 대한 방어면역을 유도하기 위한 in ovo 초회항원자극(priming)과 불활화백신에 의한 보강접종 방법에 항원보강제(adjuvant)로 chicken interleukin 6 (pcDNA-ChIL-6;plasmid encoding chicken interleukin-6)와 levamisole (LMS)의 효과를 조사하는 것이다. IBDV의 VP2, VP, VP3 protein을 암호화하는 유전자백신인 plasmid DNA vaccine (pcDNA-VP243) 단독 또는 pcDNA-ChIL-6 또는 LMS와 함께 18일령 부화란의 양막낭(amniotic sac)에 접종하고 부화한 1주령의 병아리에 불활화 IBD 백신을 근육 접종한 다음 3주령에 고병원성 IBDV인 SH/92 주로 공격 접종하고 10일 동안 관찰하였다. 백신하지 않은 공격접종 대조군이 100%의 폐사율을 보인 반면 pcDNA-VP243 단독 접종군과 pcDNA-VP243에 pcDNA-ChIL-6 또는 LMS를 첨가한 실험군은 모두 100%의 생존율을 나타내었다. 그러나 공격접종 후 F낭의 손상을 평가하기 위한 IBDV RNA의 검출, B/B ratio와 F낭의 병변지수(lesion score) 등을 분석한 결과 pcDNA-VP243에 pcDNA-ChIL-6 또는 LMS를 첨가한 실험군은 pcDNA-VP243 단독 접종군보다 향상된 방어효과를 나타내지 않았다. 이 실험결과는 유전자백신에 의한 in ovo 초회항원자극-불활화백신에 의한 보강접종법이 고병원성 IBDV로부터 닭을 보호하기 위한 효과적인 방법이었으나 pcDNA-ChIL-6 또는 LMS의 첨가로 인한 방어효과의 향상은 나타나지 않았다.

In this study, we examined transmission efficiency and expression level of the transgenes in the transgenic mice. The transgenic lines secreting a considerable amount of human lactoferrin(LF) thrombopoietin(TPO), interleukin-10(IL-10) into their milk were subjected to access the inheritance and maintenance of transgenic phenotype. They were bred through three generations. The transmission frequency for each generations(F9, F10, F11) of 3 lines was 38.03±10.43%(13/35), 48.33±3.76%(19/39) and 31.83±8.88%(9/28) in the LF line, 51.33±18.98%(20/38), 63.70±35.71%(12/20) and 29.57± 15.05%(8/26) in the TPO line, 38.27±17.74%(15/37), 47.47±29.88%(14/28) and 50.87±5.85%(14/28) in the IL-10 line, respectively.

Previously, wogonin (5,7-dihydroxy-8-methoxyflavone) was found to suppress proinflammatory enzyme expression including cyclooxygenase-2 (COX-2), contributing to in vivo anti-inflammatory activity against skin inflammation. However, the detailed effect on each skin cell type has not been understood. Therefore, present investigation was carried out to find the effect of wogonin on inflammation-associated gene expression from skin fibroblasts in culture using reverse transcriptase-polymerase chain reaction. As a result, it was found that wogonin (10 - 100 ${\mu}$M) clearly down-regulated COX -2 expression from NIH/3T3 cells treated with 12-O-tetradecanoylphorbol 13-acetate, interleukin-1${\beta}$ or tumor necrosis factor-a. But, the expression levels of COX-1, interleukin-1${\beta}$ and fibronectin were not significantly affected. This finding was well correlated with significant reduction of prostaglandin E$_2$(PGE$_2$) production by wogonin. As a comparison, NS-398 (selective cyclooxygenase-2 inhibitor) did not suppress COX -2 expression and other gene levels, while PGE$_2$production was potently reduced at 0.1 - 10 ${\mu}$M. All these results suggest that COX -2 down-regulation of skin fibroblasts may be, at least in part, one of anti-inflammatory mechanisms of wogonin against skin inflammation.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by abdominal pain, rectal bleeding and diarrhea. Gastrodia elata Blume (GE) has been used for the treatment of various diseases including neurodegenerative diseases and inflammatory disease. However, there has been no information on whether GE regulates intestinal inflammation. The aim of this study is to elucidate whether GE can protect against dextran sulfate sodium (DSS)-induced colitis in a mouse model. The colitis mice were induced by drinking water containing 5% DSS for 7 days. Body weight, colon length and clinical score were assessed to determine the effects on colitis. The levels of inflammatory cytokines, tumor necrosis factor $(TNF)-{\alpha}$ and interleukin (IL)-6 in colitis tissue were also measured. The results showed that mice administrated with DSS showed clinical signs including weight loss and reduced colon length. GE inhibited the DSS-induced loss of body weight and shortening of colon and increased Disease activity index score. Additionally, we observed that GE suppressed the levels of $TNF-{\alpha}$ and IL-6 in DSS-treated colon tissues. Collectively, these findings provide experimental evidence that GE might be a useful therapeutic agent for patients with UC.
