  • 본 실험은 Herbs와 Plant extracts(PE)가 산란계의 생산성과 소장내 미생물 균총 및 면역 체계에 미치는 영향을 조사하기 위해 실시하였다. 사양 시험은 67주령의 산란계(Hy-line Brown) 1,440수를 선별하여 A형 2단 케이지에 대조구 포함 총 9처리구로 구성하여 처리당 8반복 반복당 20수씩 randomized block design으로 배치하였다. 시험 기간 동안 물과 사료는 자유 섭취하게 하였으며, 일반적인 점등 관리(자연 일조 + 조명; 16 hr)를 실시하였다. 시험구는 대조구, 항생제구; Avilamycin 6 ppm, $Herb-Mix^{(R)}$ 0.2%구, PE-BIOSTRONG $510^{(R)}$ 0.02% 구, $PE-APEX^{(R)}$ 0.02%구, $PE-Digestarom^{(R)}$ 0.02%구, $PE-Phello-zyme^{(R)}$ 0.1%구, $PE-Galicin^{(R)}$을 0.05%구, PE-CRINA $Poultry^{(R)}$ 0.05%구 등 총 9처리구였다. 일계 산란율은 처리구간에 유의적 차이는 없었지만, 첨가구들이 대조구보다 높은 경향을 나타냈다. 사료 섭취량과 사료 요구율은 처리구간에 유의한 차이를 보였다. 사료 섭취량은 첨가구들이 대조구보다 높았다. 사료 요구율은 T8(PE-Galicin)구가 모든 첨가구중에 가장 높았다. 난각과 난황 색깔 지수는 처리구간에 유의한 차이가 있었다. 난각 색깔 지수는 첨가제간에 유의한 차이가 있었으며, 난황 색깔 지수는 T9(PE-CRINA Poultry)가 대조구보다 유의하게 높았다. Haugh unit은 처리구간에 유의적인 차이는 나타나지 않았다. Leukocytes와 erythrocytes 관련 모수들은 처리간에 유의한 차이가 있었다. WBC 수준과 stress index는 일반적으로 첨가구들이 대조구보다 높았다. RBC 수준은 Herb-Mix와 PE구들이 대조구보다 낮은 경향을 보여주었다. 혈청 IgG 농도는 처리구간에 유의적인 차이는 없었지만 모든 첨가구들이 대조구보다 높았다. 첨가구들에서 Lactobacillius는 증가하고 Cl. perfrigens는 감소하였다. E. coli는 첨가구들이 대조구보다 유의하게 낮았다. 결론적으로 herbs와 plant extract는 산란계에서 산란율을 증가시키는 경향이 있었고 혈액 성상 및 장내 미생물 균총에 유의한 영향을 미쳤다.

  • 연구배경: 정상세포는 보호되고 종양세포에 독성을 보인다고 알려진 TNF유전자족으로 새로이 확인된 TRAIL이 폐암세포에서 보이는 아포프토시스 효과를 확인하고, 아포프토시스로부터 세포를 보호하는 전사인자 $NF-{\kappa}B$가 TRAIL에 의하여 활성화 되는 정도를 평가하여 MG132의 $NF-{\kappa}B$활성억제가 TRAIL 유도성 아포프토시스를 감작시키는지를 확인하기 위하여 본 연구를 시행하였다. 방법: A549(wt p53) 및 NCI-H1299(null p53) 폐암세포주를 사용하였다. 세포독성 검사는 MTT assay를 이용하였고 아포프토시스는 Annexin V assay와 FACS 분석을 이용하였다. $NF-{\kappa}B$ 전사활성은 luciferase reporter gene assay를 이용하였고 $I{\kappa}B{\alpha}$ 분해는 western blot을 이용하였으며, TRAIL에 의해 활성화된 $NF-{\kappa}B$와 DNA 결합은 electromobility shift assay와 anti-p65 antibody를 이용한 supershift assay로 확인하였다. 결과: 1) TRAIL 100 ng/ml 농도에서 wild-type p53인 A549 폐암세포는 34.4%, p53 null인 NCI-H1299 폐암세포는 26.4%의 세포사를 관찰하였다. 2) Luciferase reporter gene assay로서 TRAIL에 의한 $NF-{\kappa}B$의 활성이 A549 $IgG{\kappa}B-luc$세포에서 2.45배 증가하고 NCI-H1299 $IgG{\kappa}B-luc$세포에서는 1.47배 증가함을 관찰하여 TRAIL에 의하여 $NF-{\kappa}B$가 활성화됨을 확인하였다. 3) MG132의 전처치로 TRAIL에 의한 $NF-{\kappa}B$의 활성이 A549 세포와 NCI-H1299 세포에서 각각 기저수준의 0.24, 0.21배로 강력히 억제되었다. 4) TRAIL단독으로 30% 전후의 세포독성이 MG132 전처치 후 TRAIL을 투여하면 두 세포주 모두에서 80% 이상의 세포독성이 관찰되어 MG132가 TRAIL유도성 아포프토시스에 감작효과가 있음을 확인하였다. 결론: 이상의 결과로 TRAIL에 상대적인 내성을 보이는 폐암세포주에서 MG132가 $NF-{\kappa}B$ 활성억제로서 TRAIL유도성 아포프토시스를 강화시키는 효과가 있음을 확인할 수 있었다. 따라서 본 연구는 향후 폐암치료에 있어서 TRAIL유도성 아포프토시스가 이용될 수 있는 가능성을 확인한 기초자료가 된다고 생각된다.

  • To investigate the effect of dietary Acanthopanax senticosus polysaccharide (ASPS) on growth performance, immunity, blood parameters and mRNA expression of pro-inflammatory cytokines in immunologically challenged piglets, an experiment employing $2{\times}2$ factorial arrangement concerning dietary ASPS treatment (0 or 800 mg/kg) and immunological challenge (lipopolysaccharide [LPS] or saline injection) was conducted with 64 crossbred piglets (weaned at 28 d of age, average initial body weight of $7.25{\pm}0.21kg$) assigned to two dietary ASPS treatments with 8 replicates of 4 pigs each. Half of the piglets of per dietary treatment were injected with LPS or saline on d 14. Blood samples were obtained at 3 h after immunological injection on d 14 and piglets were slaughtered to obtain spleen samples on d 21. Dietary ASPS did not affect average daily gain (ADG) (p = 0.634), average daily feed intake (ADFI) (p = 0.655), and gain:feed (p = 0.814) prior to LPS challenge. After LPS challenge, for LPS-challenged pigs those fed ASPS had higher ADG and ADFI than the non-supplemented group (p<0.05), and an interaction between $LPS{\times}ASPS$ was observed on the two indices (p<0.05). Dietary ASPS improved lymphocyte proliferation among saline-injected and LPS-injected pigs (p<0.05). Interaction between $LPS{\times}ASPS$ was also revealed on lymphocyte proliferation (p<0.05). Circulatory concentration of IgG was influenced neither by ASPS (p = 0.803) or LPS (p = 0.692), nor their interaction (p = 0.289). Plasma concentration and spleen mRNA expression of interleukin-1beta (IL-$1{\beta}$), interleukin-6 (IL-6), and tumor necrosis factor (TNF)-${\alpha}$ were induced to increase (p<0.05) by LPS challenge, in contrast, these indices were decreased by dietary ASPS (p<0.05), and interactions were found on these cytokines (p<0.05). For LPS-challenged pigs, dietary ASPS also reduced the circulating concentration and spleen mRNA expression of IL-$1{\beta}$, IL-6 as well as TNF-${\alpha}$ (p<0.05). The interaction between $LPS{\times}ASPS$ was also observed on the circulating concentration of insulin-like growth factor-I, ${\alpha}$-acid glycoprotein (${\alpha}$-AGP), nonesterified fatty acid, and glucose (p<0.05). The results of this study demonstrate that dietary ASPS can modulate the release of pro-inflammatory cytokines during immunological challenge, which might enable piglets to achieve better growth performance.

  • 본 실험은 가공한 육제품에 첨가된 대두단백질(soy protein)을 정량하기 위한 면역분석(Immunoassay)법의 개발을 목적으로 실시하였다. Isolated soy protein(ISP)의 whole buffer extract(WBE) 분획을 SDS 처리 후 토끼에 주사하여 생산된 항혈청의 항체역가를 indirect ELISA법으로 조사하였을 시 1 : 10,000 이상에서도 반응을 나타내었다. 시료의 처리시 SDS의 최종농도가 0.03% 이상에서는 항원-항체 반응이 심각하게 저지되었으나, 0.02% 이하에서는 거의 영향을 미치지 않았다. 본 실험에 사용한 항체는 SDS로 변성된 항원(대두단백질)은 물론 SDS를 투석으로 제거한 재생항원(renatured antigen)과도 반응하였으나 그 정도는 변성항원에 비하여 약간 낮았다. 검정곡선(calibration curve)을 indirect competitive ELISA 법으로 작성하였을 시 ISP를 100 ng/100 ml까지 측정할 수 있는 감도(sensitivity)를 얻었다.

  • 본 연구에서는 DNCB 도포를 통해 아토피 피부염을 유발시킨 NC/Nga mice에 율피 발효물을 각각 0.1%, 1%, 5%로 도포하고 항아토피 효능을 평가하였다. 율피 발효물의 유효성분은 HPLC 분석 결과, gallic acid와 ellagic acid가 각각 10.18 mg/g, 2.14 mg/g 함량을 나타내었다. 실험군 간의 유의적 체중 변화는 관찰되지 않았으며, 육안 평가를 통해 홍반, 가려움과 피부건조, 부종과 혈종, 짓무름 그리고 태선화와 같은 일반적인 아토피 피부염 증상의 심각도를 측정한 점수 결과에서는 DNCB 도포를 통해 아토피 피부염을 유발한 atopic dermatitis(AD)군($13.17{\pm}0.40$)과 비교 시, 아토피 피부염 유발 후 5% 율피 발효물을 도포한 fermented Castanea crenata inner shell(FCS) 5군에서 $7.50{\pm}0.43$ 으로 나타나 아토피 피부염 증상이 빠르게 개선되는 것을 확인하였다(P<0.01). 피부 측정 기기인 MPA5 580을 이용하여 피부멜라닌지수, 피부홍반지수, 피부수분지수를 측정한 결과, AD군은 각각 $296.61{\pm}8.11$, $264.33{\pm}10.15$, $3.15{\pm}0.54$를 나타내었으며 FCS 5군은 각각 $105.86{\pm}2.92$, $199.56{\pm}4.22$, $17.62{\pm}1.75$로 개선효과가 유의적으로 나타났다(P<0.05). 각 실험군 mice의 면역반응을 확인하기 위해 비장 무게(mg)를 체중(g)으로 나누어 산출한 비장 수치의 경우, 아토피 피부염 유발로 인해 AD군에서 증가된 비장 수치($5.55{\pm}0.31$)가 FCS 0.1군, FCS 1군, FCS 5군에서는 각각 $4.53{\pm}0.24$, $3.80{\pm}0.40$, $3.32{\pm}0.24$로 나타나 율피 발효물의 도포 농도에 의존적으로 감소되는 경향을 나타냈으며 특히 FCS 5군에서는 유의적으로 낮게 나타났다(P<0.05). 이는 율피 발효물이 아토피 피부염 상태에서 증가된 비장 내 T-림프구를 효과적으로 억제할 수 있음을 나타낸다. Quantitative real-time PCR을 통해 피부조직에서 IL-$1{\beta}$, TNF-${\alpha}$와 같은 염증 유전자의 발현 변화를 분석한 결과, 두 유전자 모두 정상군의 relative quantification값이 1일 때 AD군은 각각 1.30, 1.26으로 증가되었으며 FCS 5군에서는 1.11, 0.93으로 나타나 율피 발효물 도포에 의한 유의적인 감소(P<0.05)를 확인할 수 있었다. 아토피 피부염의 면역학적 지표인 혈청 내 IgE 함량을 분석한 결과에서는 각 실험군 간의 유의적 차이는 보이지 않았으나 AD군($1,628.71{\pm}202.59ng/mL$)과 비교 시, 율피 발효물을 도포한 FCS 0.1군, FCS 1군, FCS 5군에서 각각 $1,530.15{\pm}198.70ng/mL$, $1,462.15{\pm}83.79ng/mL$, $1,187.47{\pm}140.09ng/mL$로 나타나 율피 발효물 도포에 의해 감소되는 경향을 확인할 수 있었다. 따라서 율피 발효물은 아토피 피부염 증상 개선을 위한 기능성 천연물의 소재로 활용될 수 있을 것이라 생각된다.

  • This experiment was conducted to investigate the effects of dried mealworm (Tenebrio molitor larva) on growth performance, nutrient digestibility and blood profiles in weaning pigs. A total of 120 weaning pigs ($28{\pm}3days$ and $8.04{\pm}0.08kg$ of body weight) were allotted to one of five treatments, based on sex and body weight, in 6 replicates with 4 pigs per pen by a randomized complete block design. Supplementation level of dried mealworm was 0%, 1.5%, 3.0%, 4.5%, or 6.0% in experimental diet as treatment. Two phase feeding programs (phase I from 0 day to 14 day, phase II from 14 day to 35 day) were used in this experiment. All animals were allowed to access diet and water ad libitum. During phase I, increasing level of dried mealworm in diet linearly improved the body weight (p<0.01), average daily gain (ADG) (p<0.01) and average daily feed intake (ADFI) (p<0.01). During phase II, ADG also tended to increase linearly when pigs were fed higher level of dried mealworm (p = 0.08). In addition, increasing level of dried mealworm improved the ADG (p<0.01), ADFI (p<0.05) and tended to increase gain to feed ratio (p = 0.07) during the whole experimental period. As dried mealworm level was increased, nitrogen retention and digestibility of dry matter as well as crude protein were linearly increased (p = 0.05). In the results of blood profiles, decrease of blood urea nitrogen (linear, p = 0.05) and increase of insulin-like growth factor (linear, p = 0.03) were observed as dried mealworm was increased in diet during phase II. However, there were no significant differences in immunoglobulin A (IgA) and IgG concentration by addition of dried mealworm in the growth trial. Consequently, supplementation of dried mealworm up to 6% in weaning pigs' diet improves growth performance and nutrient digestibility without any detrimental effect on immune responses.

  • Objective: This experiment was conducted to evaluate the effects of different levels of dietary crude protein (CP) on growth performance, blood profiles, diarrhea incidence, nutrient digestibility, and odor emission in weaning pigs. Methods: A total of 240 weaning ([Yorkshire×Landrace]×Duroc) pigs (8.25±0.050 kg body weight [BW]) were assigned to six treatments based on sex and initial BW, with five replicates of eight pigs per pen in a randomized complete block design. Experimental diets with different crude protein levels for early and late weaning phases were as follows: i) CP16, corn-soybean-based diet containing 16%/15% CP; ii) CP17, corn-soybean-based diet containing 17%/16% CP; iii) CP18, corn-soybean-based diet containing 18%/17% CP; iv) CP19, corn-soybean-based diet containing 19%/18% CP; v) CP20, corn-soybean-based diet containing 20%/19% CP; and vi) CP21, corn-soybean-based diet containing 21%/20% CP. Results: In the early weaning period, average daily feed intake increased when the dietary CP level decreased (linear, p<0.05). During the entire experimental period, average daily gain and the gain to feed ratio decreased when the dietary CP level increased (linear, p<0.01). Additionally, a decrease in dietary CP level resulted in a linear increase in final BW (linear, p<0.05). In the early and late weaning periods, blood urea nitrogen (BUN) decreased when the dietary CP level decreased (linear, p<0.01). There were no significant differences in creatinine, glucose, total protein, triglyceride or insulin-like factor-1 levels over the experimental period. The concentrations of immunoglobulin A (IgA) and IgG were not significantly affected by dietary CP levels during the experimental period. In the early weaning period, fecal and urine N decreased when the dietary CP level decreased (linear, p<0.01). No differences in nutrient digestibility among the treatments during the early weaning period were found. Throughout the whole experimental period, when the dietary CP level decreased in the weaning pig diet, the diarrhea incidence decreased linearly (linear, p<0.01). Throughout the whole experimental period, when the dietary CP level decreased in the weaning pig diet, ammonia, amines and hydrogen sulfide decreased linearly (linear, p<0.01). Conclusion: Reducing dietary CP could decrease diarrhea incidence, the concentration of BUN in serum and odor emission in manure. Furthermore, it could improve N excretion in feces and urine and growth performance in weaning pigs.

  • This paper was performed to estimate interrelations between humus level of sediments and nutrient release from sediments in Dae-cheong reservoir. For investigations, sediments were sampled in June and October, in 1997 at fish farms, embayment, and the main stream of Dae-cheong reservoir. Items for investigation are as follows; water content, weight loss on ignition(IG), porosities of sediments, contents of element such as hydrogen, nitrogen, carbon, and nutrient release rates. Water contents and porosities were measured to conjecture the physical trait and grain size trait. Weight loss on ignition was measured to determine the contents of organic substance. For determination of the humus level of sediments, carbon and nitrogen contents were measured by elemental analyzer. As a result of elemental analysis, C/N ratio was determined in the range of $3.0\~13.1$. From the elemental analysis, humus level of Dae-cheong reservoir sediment was estimated from mesohumic state to oligotrophic state. For the determination of nutrient release rate, $PO_4-P$ and $NH_4-N$ concentrations of interstitial water and overlying water were measured. By using the concentration difference between interstitial water and overlying water and using the Fick's diffusion law, the release rates of phosphorus and nitrogen from the sediment samples were calculated. Release rates of nutrients which directly influence to the water quality were $0.05\~8.63mgP/m^2day$ and $4.99\~36.56mgP/m^2day$. It was found that release rate was measured higher in the 1st sampling period than in the 2nd sampling period. For the determination of phosphorus content in sediment, TPs were measured in 807\~1542{\mu}g/g$ in the 1st samling period and $677\~5238{\mu}g/g$ in the End samling period. Phosphorus release rate and phosphorus content were not interrelated each other.

  • Objective : Pamooltang (PM) and Sipjeondaebotang (SC) are used in Korea to treat many diseases such as sterility, menstrual disorder, and general prostration. We made a comparative study of PM and SC which are different in component ratio between Astragalus membranaceus BUNGE (AC) and Cinnamomum cassia PRESL. (CC). Methods : Anti-oxidation was studied by 1.1.-diphenyl-2-picrylhydrazyl (DPPH) assay and anti-inflammation was investigated by prostaglandin $E_2\;(PGE_2)$ and nitric oxide (NO) inhibition assay. For immune response activities, this study used NO synthesis on RAW 264.7 cells and splenocyte proliferation. Results : The results showed that PM and SC components had no significant effect of anti-oxidation or anti-inflammation. However, we observed their effects upon inducible NO synthesis in Raw 264.7 cells. The SC2 stimulated NO synthesis $11.42\pm1.36{\mu}M$ (control; $0.89\pm0.00{\mu}M$). PM and SC components had the effect of immune response which in a dose-dependent manner significantly induced the splenocyte proliferation. The splenocyte proliferation induced by SC2 was higher than others at the concentration of 1, 10, 100, 1000 and 2000 ${\mu}g/ml$. The SC8 was shown to up-regulate IgG, 100 ${\mu}g/ml$ 3.3 times, 1000 ${\mu}g/ml$ 2.6 times as a control. Conclusions : These results may have important implications for our understanding of the ratios of AC and CC in SC.

  • Gami-Sopungsan (GS) is one of the traditional korean remedy. We investigated the anti-inflammation and anti-atopic dermatitis (AD) effect of GS. No cytotoxicity of GS was observed in the range of $1{\sim}100{\mu}g/m{\ell}$ on Raw 264.7 cells. The Inflammatory response of Raw 264.7 cells were induced by lipopolysaccharide (LPS), followed by GS treatment at indicated concentrations (0, 1, 10 and $100{\mu}g/m{\ell}$). At $100{\mu}g/m{\ell}$ concentration, GS showed inhibitory effect on LPS-induced nitric oxide production by 20%. Production of IL-$1{\beta}$, IL-6 and TNF-${\alpha}$ was decreased by approximately 56%, 36% and 79%, respectively upon GS treatment at $100{\mu}g/m{\ell}$. 200 mg/kg of GS was orally administered to NC/Nga mice, where AD was induced by 1-chloro 2,4-dinitrobenzene. There were no significant difference between GS treated group and the control group on body weight and food intake changes during growth. The back skin of GS group showed decrease in erythema, pruritus, dry skin, edema, excoriation, erosion and lichenification level through naked eye observations. In addition, leukocyte infiltration and the thickness of epidermis were significantly decreased in the skin tissues (back and ear). The serum IgE levels were decreased by 28.8% in the GS treated group. The GS treated group showed remarkable inhibition of IL-4 (83%), IL-5 (95%), IL-6 (62%) and TNF-${\alpha}$ (84%) in serum, indicating that GS has similar or higher efficacy than those of the dexamethasone treated group. From the results above, we conclude that GS has significant anti-inflammation and anti-AD effects on Raw 264.7 cells and NC/Nga mice. The results should provide fundamental and valuable data for the research on natural products being developed against atopic dermatitis.
