Background and objective: This study was conducted to examine changes in the composition and physiological activity of Gardenia Fructus after being roasted. Methods: The antioxidant, anti-inflammatory and antibacterial activity of Gardenia Fructus was evaluated using the Gardenia Fructus (GF) and roasted Gardenia Fructus (RGF) ethanol extracts, and their components were analyzed through HPLC. Results: As a result, it was confirmed that the content of gardenoside and geniposide decreased and the content of genipin increased when GF was roasted. The total content of polyphenols was 54.5 ± 2.18 mg gallic acid equivalents (GAE) per gram of the GF extract and 69.6 ± 0.36 mg GAE per gram of the RGF extract. As a result of evaluating 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, both the GF and RGF extracts showed the similar activity to ascorbic acid at the concentrations of 1 mg/mL or higher. In RAW 264.7 macrophages stimulated by lipopolysaccharides (LPS), the RGF extract showed a higher effect of reducing NO production, and significantly reduced the expression of an inflammatory cytokine, IL-6. As a result of evaluating the antimicrobial activity, the RGF extract showed higher antimicrobial activity against Escherichia coli and Bacillus subtilis. In the dextran sulfate sodium salt (DSS) induced inflammatory bowel disease mouse model, the RGF extract reduced the weight of the spleen, and both the GF and RGF extracts reduced the number of bacteria in the colon. Conclusion: Therefore, it has been confirmed through this study that roasting at a high temperature changes the main components of the GF extract and increases its biological activity. The RGF extract is expected to be used as a natural material with antioxidant, anti-inflammatory and antibacterial effects.

BACKGROUND/OBJECTIVES: Poorly regulated inflammation is believed to be the most predominant factor that can result in a wide scope of diseases including atopic dermatitis (AD). Despite many studies on the effect of pear pomace in obesity-related disorders including dysregulated gut microbiota, the protective effect of pear pomace in AD is still unknown. This study aimed to evaluate the effect of pear pomace ethanol extract (PPE) on AD by inhibiting inflammation. MATERIALS/METHODS: In the in vivo experiment, 2, 4-dinitrochlorobenzene (DNCB) was applied to NC/Nga mice to induce AD-like skin lesions. After the induction, PPE was administered daily by oral gavage for 4 weeks. The clinical severity score, serum IgE levels, spleen weight, histological changes in dorsal skin, and inflammation-related proteins were measured. In the cell study, RAW 264.7 cells were pretreated with PPE before stimulation with lipopolysaccharide (LPS). Nitrite oxide (NO) production and nuclear factor kappa B (NF-𝛋B) protein expression were detected. RESULTS: Compared to the AD control (AD-C) group, IgE levels were dramatically decreased via PPE treatment. PPE significantly reduced scratching behavior, improved skin symptoms, and decreased ear thickness compared to the AD-C group. In addition, PPE inhibited the DNCB-induced expression of inducible nitrite oxide synthase (iNOS), the receptor for advanced glycation end products, extracellular signal-regulated kinase (ERK) 1/2, and NF-𝛋B. PPE inhibited the LPS-induced overproduction of NO and the enhanced expression of iNOS and cyclooxygenase-2. Moreover, the phosphorylation of ERK1/2 and NF-𝛋B in RAW 264.7 cells was suppressed by PPE. CONCLUSIONS: These results suggest that PPE could be explored as a therapeutic agent to prevent AD.

This study aimed to identify the optimum level of supplementary feeds on the carcass traits and meat quality of Jamuna basin lambs. Forty selected lambs were divided into four treatments such as T₀ (no concentrate supplementation), T₁ (1% concentrate feed), T₂ (1.5% concentrate feed) and T₃ (2% concentrate feed) having ten lambs per treatment. The data were analyzed through Completely Randomized Design (CRD) with SAS software. Hot carcass, dressing percentage, head, leg, neck, loin, heart, and spleen weight were showed significantly (p < 0.05) higher values with increasing concentrate feed. The crude protein (CP), ether extract (EE) and ash values were significantly increased (p < 0.001) except T₂ treatment. The ultimate pH was significantly increased except T₂ and cooked pH was significantly decreased (p < 0.001) except T₃ treatment. Drip loss and cooking loss (CL) % had significantly reduced (p < 0.001) except T₃ treatment. The water holding capacity (WHC) % was significantly increased (p < 0.001) except T₃ treatment. The score of color, juiciness and tenderness were significantly different (p < 0.001). Flavor and overall acceptability score were significantly increased (p < 0.05) in different treatments. The color values L^* and b^* had significantly changed (p < 0.001) and a^* value was found significantly higher (p < 0.05) in all treatments. Hence, 12 months of aged lambs with 1.5% concentrate feed showed better performances on carcass, nutritional, physicochemical, sensory and instrumental color values to increase the carcass and the meat quality of lambs.

본 연구에서는 ${\omega}$-6 및 ${\omega}$-3계 지방산을 함유한 유지의 첨가비율을 달리한 실험사료를 어린 병아리에서 급여했을 때 면연 기관의 지방산조성에 미치는 영향을 조사하였다. 5개의 처리구에 각 처리당 3반복을 두고 총 75수의 1일령 수평아리를 공시하였다. 옥수수유(CO)와 들깨유(PO)를 중량비로 각각 8%+0%, , 6%+2%, 4%+4%, 2%+6%, 0%+8% 수준으로 첨가한 반정제 실험 사료를 7주간 급여하였다. 실험 종료시 증체량 및 사료섭취량은 처리 간에 큰 차이가 보이지 않았으며 체중 100g당 간장 중량 및 면역 기관 중량에서도 유의한 차이가 인정되지 않았다. 면역조직 내 지방산 조성은 EPA와 AA(arachidonic acid)를 포함하여 섭취한 사료 지방산의 조성을 잘 반영하는 경향을 보였는데, 면역기관 간에 그 정도에 차이가 있었다. 들깨유의 첨가수준이 증가함에 따라 linoleie acid LA)의 비율이 점진적으로 감소하였고 반면 a-linolenic acid(LNA) 비율은 현저하게 증가하는 경향이었다. 흉선에는 .LA와 LNA의 함량이 다른 조직보다 현저히 더 많아서 섭취하는 지방산의 조성이 가장 잘 반영되었다. 비장 조직에는 HPA 및 AA 농도와 EPA/LNA, AA/LA의 비율이 다른 조직에 비해 현저히 더 높았는데 이는 비장이 LA나 LNA로부터 AA나 EPA로 전환하는 능력이 높음을 의미한다. 실험사료 급여후 2, 4주후에 조사된 anti-BSA 항체가 유의한 차이는 인정되지 않았으나 CO 8%구에 비해 PO를 첨가한 모든 구에서 더 많이 생성되는 경향이 관찰되었고 특히 PO를 6% 및 8% 첨가한 실험구에서 20~30%나 더 높아졌다. 결론적으로 섭취하는 지방산 조성에 따라 면역기관내 모든 지방산 조성이 변하였으며, 면역기관에 따라 그 반응정도가 달라지는 것이 관찰되었다. 이는 eicosanoids 합성에도 영향을 미칠 수 있기 때문에 가금에서 질병에 대한 면역력 향상이라는 관점에서 앞으로 더 세밀한 연구가 필요하다.

계사 사육 형태에 따른 닭의 스트레스 정도를 알아보기 위하여 단관백색레그혼종을 대상으로 케이지 사육 및 평사 사육으로 관리 후 이들의 생산 능력과 스트레스 관련 표지를 비교 분석하였다. 개체의 생산 능력에 있어 생존율, 산란 지수, 난중 및 체중은 평사 사육군이 케이지 사육군에 비해 유의하게 높은 성적을 보였고, 반면 초산 일령 및 난질의 경우 케이지 사육군이 양호한 결과를 나타내었다. 사육 형태에 따른 닭의 스트레스 관련 표지로 형광접합보인법에 의한 텔로미어 함량 분석 및 comet assay에 의한 DNA 손상율을 비교 분석하였다. 텔로미어 함량 분석 결과, 혈액 세포 및 신장, 비장 세포의 경우 평사 사육군이 케이지 사육군에 비해 유의하게 높은 텔로미어 함유율을 보이고, 연령이 증가함에 따라 이의 차이는 더욱 커지는 것으로 나타났다. DNA 손상율은 케이지 사육군이 평사 사육군에 비해 유의하게 높은 손상율을 나타내어 케이지 사육이 평사 사육에 비해 훨씬 높은 스트레스 상태임을 알 수 있었다. 따라서 생존율을 포함한 생산 능력과 스트레스 표지 분석 결과, 산란계에 있어 케이지 사육 방식이 평사 사육 방식보다 개체들에게 생리적 스트레스 요인이 상대적으로 큰 것으로 사료된다.

Objective: The purpose of experimental study was to prove the effects of Boyangmakseong-bang (BYMSB) treatment on cBSA-induced in a MN mouse model. Methods: We divided mice into 4 groups. The Normal group had no treatment. We used cBSA and induced MN mouse model to the other 3 groups. The Control group was treated with cBSA (9mg/kg i.p) only. The second group, named 'BY-250', was treated with cBSA (9mg/kg i.p) and BYMSB extract (250mg/kg, p.o). The third group, named 'BY-500', was treated with cBSA (9mg/kg i.p) and BYMSB extract (500mg/kg, p.o). After cBSA and BYMSB extract treatment for 4 weeks, the increase in percentage of body weight, proteinuria, serum albumin, total cholesterol, creatinine and BUN of all groups were measured. The CD3+, CD19+, CD4+, CD8+ cell levels of spleen of all groups were analyzed. IgA, IgG, IgM, IL-$1{\beta}$, TNF-${\alpha}$, IL-6 and IFN-${\gamma}$ levels of all groups were gauged. H&E staining, immunofluorescence staining and electron microscopy of kidney were observed. Results: BYMSB showed significant decrease in the 24hrs proteinuria, serum total cholesterol, serum IgG levels and BUN levels, and showed significant increase in the serum albumin levels compared with the control group. BYMSB showed increase in the increasing percentage of body weight and IFN-${\gamma}$ levels compared with the control. BYMSB showed decrease in the CD3+ T cells, CD4+ Th cells, IL-$1{\beta}$, TNF-${\alpha}$ and IL-6 levels, but did not show significant change compared with the control. BYMSB showed considerable decrease in the thickening of the GBM on H&E staining, deposition of IgG on immunofluorescence staining and deposition of electron-density on electron microscopy of kidney compared with the control. Conclusions: According to the above results, it is suggested that BYMSB decreases the symptoms of MN induced by cBSA in a mouse model. Therefore BYMSB seems to be applicable to MN in clinical practice.

Objective : Yinjinchunggan-tang(YJCGT) is reported previously as having theraputic effects on hepatitis such as anti-implammatory, anti-apoptotic, anti-viral(HBV), etc. Though this prescription is not studied on its anti-fibrogenic effect, it is still expected to have the effect in the liver. Thus, this study was performed to investigate the anti-fibrogenic effect of YJCGT on thioacetamide(TAA)-induced liver fibrosis in rats. Method: Rat liver fibrosis was induced by intraperitoneal TAA injection(150mg/kg) 3 times a week for 5 weeks. After the YJCGT (YJCGT 1g/kg, YJCGT 2g/kg)-treatment, body weight, liver and spleen weights, liver function test, the complete blood count and the portal pressure were studied. In addition, gene expressions of ASMA, procollagen type Ia2, MMP2, TIMP1 and TIMP2, all of which are known to be associated with liver fibrosis, were analyzed by RT-PCR. After YJCGT (YJCGT 1g/kg, YJCGT 2g/kg) treatment, percentages of collagen in TAA-induced rat liver tissue were measured by image analyzer. Results : The body weight of the normal group increased more than that of the control and YJCGT-treated groups. The AST level of the YJCGT lg/kg-treated group significantly decreased compared to that of the control. The ALT and the GGT levels of the YJCGT 2g/kg-treated group significantly increased compared to those of the control. In the YJCGT-treated groups. WBC, RBC and Hgb elevated by TAA injection decreased but platelet count increased. In the YJCGT lg/kg-treated group, the portal pressure elevated by TAA injection significantly decreased. The significant decreases in the gene expressions of procollagen type Ia2, MMP2 and TIMP2 were observed in the YJCGT-treated groups. In histological findings. TAA injections caused severe liver fibrosis, but the YJCGT treatment significantly reduced the amounts of hepatic collagens. Conclusions: These results suggest that YJCGT has beneficial effects on the treatment of patients with liver cirrhosis as well as chronic hepatitis. Further study should be done to decide the optimal concentration of the YJCGT for the treatment of liver cirrhosis.

저령의 균핵으로부터 중성염용액, 열수 및 메탄올 추출물을 분리하였다. 세포독성 실험 결과, 중성염용액 추출물은 $0{\sim}2,000\;{\mu}g/ml$의 농도에서 NIH3T3, Sarcoma 180 및 MCF-7에 대한 세포독성이 없었으나, 메탄올 추출물에서는 $1,000\;{\mu}g/ml$ 이상의 농도에서는 독성을 나타내었다. Sarcoma 180 복수암에 대한 항암 효과는 중성염용액 추출물을 투여한 실험군에서 66.74%의 높은 생명 연장 효과를 나타내었으며, 암세포의 생 세포 수 또한 54.2% 감소시키는 효과를 나타내었다. 중성염용액 추출물은 대조군에 비해 보체 대체 경로에서의 항보체 활성을 $85.05{\sim}88.73%$, B 임파구의 alkaline phosphatase 활성을 6배 이상 증가시킴으로써 면역 활성 효과를 향상시켰다. 또한 중성염용액 추출물을 50 mg/kg body weight의 농도로 마우스 복강에 투여하였을 때 대조군에 비하여 복강세포수가 1.7배 증가하였으며, 혈액 내 백혈구 수 또한 3.6배의 증가를 나타내었다. 간, 비장 및 흉선 등의 면역 관련 장기의 체중에 대한 중량을 측정한 결과, 중성염용액 추출물 투여군은 대조군에 비해 증가된 수치를 보였으며, 혈액생화학적 검사를 시행한 결과, 대조군과 유사한 경향을 나타내었다. 중성염용액 추출물의 총 다당류와 단백질의 함양은 각각 98.25%와 1.44%로 측정되었다. 따라서 저령균핵의 중성염용액 추출물의 항암 효과가 암세포에 대한 직접적인 세포독성에 의한 것이 아니고 면역활성에 의한 것으로 판단된다.
