  • 본 시험은 한우암소의 유전능력과 산차에 따른 분만 전후 체중과 BCS, 생리상태와 관련된 혈중 스트레스 및 혈중 영양대사물질의 변화를 조사하여, 모축의 유전능력을 고려한 분만 전후 차별적 사양기술 개발을 위한 기초자료 확보를 위하여 수행하였다. 공시축은 모체 유전능력(포육력) 효과 판별분석을 통해 선발된 분만 예정축 45두를 공시하여 분만전 60일부터 분만후 120일까지 총 180일간 본 연구에 이용하였다. 시험구 배치는 선발된 분만 예정축 45두를 모체 유전능력에 따라 두 개의 시험 처리구를 두었다. 즉, 육종가 0.23 이상인 것을 유전능력이 높은 시험축 24두, 0.21 이하인 것을 유전능력이 낮은 시험축 21두를 배치하였으며, 선발된 공시축의 유전능력별 평균 산차는 각각 2.83±1.63과 3.00±1.77이었다. 시험결과는 공시축의 체중, 일당증체량 및 body condition score(BCS)는 유전능력에 상관없이 두 시험구간 통계적 유의차이는 없었지만, 분만 전후 일령에 의한 차이는 보였다. 한편 일당증체량과 BCS는 공시축의 산차에 의한 영향은 받지 않았지만, 체중의 경우에는 산차에 따라서 차이를 나타냈었다. 공시축의 혈중 생리적 스트레스 관련 물질인 neutrophil, hematocrit 및 cortisol의 농도와 영양대사관련 물질인 albumin, blood urea nitrogen(BUN), 및 triglyceride, non- esterified fatty acid(NEFA)는 분만 전후 일령에 따른 차이가 크게 나타났으며, 유전능력에 따른 이들 물질의 농도는 일령별로 부분적인 차이를 보였다. 산차에 따른 혈중 이들 물질의 변화는 neutrophil과 triglylceride 농도만 영향을 받았고, 나머지는 영향을 받지 않았다. 따라서 한우의 모유 합성과 분만의 개시와 관련된 생리적 스트레스는 건물섭취량 감소와 영양소의 불균형 섭취로 인해 에너지원으로 이용할 체조직의 분해가 증가하므로 분만 전후 생리영양학적 특성을 고려한 유전능력별 사양관리의 차별화가 필요할 것으로 사료된다.

  • 산업화를 위한 지구자 및 12가지 식물성 원료 추출물의 생리학적 효과를 평가하기 위하여, 만성 에탄올을 투여한 마우스 혈청 내에서의 생리학적 지표 및 간과 뇌 조직 내에서의 산화적 스트레스에 대한 보호효과를 확인하였다. 에탄올을 투여한 마우스의 혈당은 정상 대조군 그룹(NG)과 에탄올 투여 그룹(EG)에서 각각 119.43mg/dL, 305.25mg/dL로 나타났고, 에탄올과 혼합 추출물을 동시에 투여한 그룹(100, 200mg/kg body weight + 25% ethanol 5g/kg body weight, ME100, ME200)에서 각각 272.76mg/dL, 234.60mg/dL로 감소하였다. 혈중 에탄올 함량은 EG에서 4.08mg/dL를 나타내었고 ME100, 200에서 각각 3.85mg/dL, 3.08mg/dL로 감소하였으며, 혈중 아세트알데하이드 함량은 18.72mg/dL에서 각각 15.76mg/dL, 15.16mg/dL로 감소하였다. 또한 ME100, ME200은 혈청 내의 생리학적 지표에서 간 독성 지표인 glutamine pyruvic transaminase(GPT), glutamic oxaloacetic transaminase(GOT)와 신장 독성 지표인 blood urea nitrogen(BUN), creatine(CRE), 혈중 total cholesterol(TCHO), triglyceride(TG)의 함량이 유의하게 감소하였다. 뇌 조직에서 에탄올에 의해 acetylcholinesterase(AChE)가 EG(116.10%)에서 NG(100.00%)와 비교하였을 때 증가된 활성을 나타냈으나, ME에서 각각 109.00%와 108.47%로 유의적으로 감소하였다. ME에서 EG에 비해 간과 뇌 조직에서 superoxide dismutase(SOD)의 함량이 증가하였고, oxidized glutathione(GSH)/total GSH 비율과 malondialdehyde(MDA)의 함량이 감소하였다. 이러한 결과들을 통해 지구자를 포함한 혼합 추출물은 간, 뇌 조직 및 혈액 등에서 만성 에탄올 섭취에 의해 유발된 산화적 스트레스를 효과적으로 보호할 수 있는 제품으로의 개발이 가능할 것으로 판단된다.

  • Experiments were undertaken to examine the ability of selenium to protect against alcohol and/or paraquat-induced hepatotoxicity and to examine the additive effect between alcohol and paraquat. Protective effect against hepatotoxic functions was measured in serum from alcohol(15% v/v), paraquat(200ppm), alcohol and paraquat, and combination of sodium selenite(4ppm) in drinking water-fed guinea pigs ad libitum for 4 weeks. A total of 68 healthy 7-weeks-old male animals were assigned at random to 8 treatment groups(9~13 animals/group). Body and liver weight losses, and high serum concentrations in aspartate aminotransferase(AST), alanine aminotransferase(ALT, in only paraquat group), $\gamma$-glutamyltranspeptidase($\gamma$-GTP), cholesterol(Cho), creatinine, blood urea nitrogen(BUN), total bilirubin(TB), direct bilirubin(DB), total protein(TP), albumin and globulin as well as low values in alkaline phosphatase(ALP) and glucose were produced in a groups of alcohol or paraquat-fed. These values were not potentiated in a group given the combination of alcohol plus paraquat. Morphological changes in the liver were also observed in the alcohol or paraquat-fed group. Lipid droplet and cell swelling in the hepatocytes were observed in alcohol-fed guinea pig, especially Mallory's hyaline arounded hepatic vein. In the paraquat-fed guinea pig, lipid droplet, pyknosis and karyolysis were observed. When alcohol or paraquat was combined with selenium-fed, hyperplasia of Kupffer cell in liver were observed. However, the mean ALT, $\gamma$-GTP, Cho, BUN, TB, TP, albumin and globulin values were lower in groups given the combination of alcohol and/or paraquat plus selenium, compared with groups given alcohol and/or paraquat. Also, the ratio of liver weight to body weight and ALP values(exception of paraquat plus selenium group) were increased by selenium. These results suggest that an adequate selenium confers marked protection against alcohol and paraquat-induced hepatotoxicity.

  • Background: Multiple myeloma (MM) is a haematological cancer characterized by clonal proliferation of plasma cells.The aim of this study was to investigate the activity of serum paraoxonase-1 (PON1) and arylesterase (ARE) in multiple myeloma with and without free light chain excretion(FLCe-MM and NFLCe-MM); as well as to investigate possible alterations in oxidative stress parameters. Materials and Methods: Total thiol (T.thl), oxidative stress index (OSI), total oxidant status (TOS) and total antioxidant status (TAS) were examined in addition to the PON1 and ARE enzyme activities in twenty one FLCe-MM and nineteen NFLCe-MM subjects. Routine parameters like lipid panel, serum total protein, albumin, creatinine, blood urea nitrogen (BUN), uric acid and hemoglobin levels were compared with the oxidative stress markers. Results: Serum total protein, BUN, creatinin, and uric acid levels were significantly higher (p=0.04, p=0.001, p=0.001 and p=0.0022, respectively), while hemoglobin and albumin levels were significantly lower in FLCe-MM patients (p=0.009 and p=0.04,respectively). PON1 and ARE activities were significantly lower in patients with FLCe-MM compared to those with NFLCe-MM (p=0.001 and p=0.008, respectively). Conclusions: Depending on our results of prognostic markers of MM such as age, hemoglobin, albumin, and creatinine we feel confident to presume FLCe-MM as a subgroup with a worse prognosis. A decrease in PON1 and ARE activities may contribute to the prognosis and may be used as a prognostic tool in MM.

  • Objectives This study was designed to evaluate the bone regeneration effects of Sintongchukea-tang (SC) on rib fractured rats. Methods Rats were randomly divided into 5 groups (normal, control, positive control, SC low [SC-L] and SC high [SC-H]). All groups were subject to fractured rib except normal group. Normal group received no treatment at all. Control group was orally fed with phosphate buffered saline, and positive control group was medicated with tramadol (20 mg/kg). SC group was orally medicated with SC (50 mg/kg, 100 mg/kg) once a day for 14 days. The fracture healing process was observed by x-ray, micro CT and fracture tissue slide was observed by immunohistochemical staining. We analysed levels of transforming growth factor-β1, Ki67, alkaline phosphatase (ALP), runt-related transcription factor 2 (Runx2), receptor activator of nuclear factor kappa-β, tartrate resistant acid phosphatase (TRAP) and analysed levels of Osteocalcin in plasma. We measured levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), ALP, blood urea nitrogen (BUN) and creatinine in plasma, for hepatotoxicity and nephrotoxicity of SC. Results Though X-ray and micro-computed tomography, more callus formation was observed and bone union was progressing. Through Hematoxylin and Eosin, callus formation was increased compared to the control group. Runx2 level at SC-H was significantly increased and TRAP level at SC-L was significantly decreased compared with the control group. AST, ALT, ALP, BUN and creatinine were not statistically different from the control group. Conclusions As described above, SC promoted fracture healing by stimulating the bone regeneration factor. And SC shows no hepatotoxicity and nephrotoxicity. In conclusion, it seems that SC helps to promote fracture regeneration and it can be used clinically to patients with fracture.

  • Melamine-induced nephrotoxicity is closely associated with crystal formation in the kidney caused by combined exposure to melamine (Mel) and cyanuric acid (CA). However, there are few dosage-finding studies for toxicological evaluation of chronic co-exposure to Mel and CA. The objective of this study was to investigate the possible mechanism by which a Mel and CA mixture lead to renal toxicity in rats. Mel and CA were co-administered to rats via oral gavage for 50 days. Nephrotoxicity was determined by measuring blood urea nitrogen (BUN) and serum creatinine (sCr) levels. Relative kidney weights were significantly increased in rats after co-exposure to Mel+CA (63/6.3 or 630/6.3 mg/kg) mixtures. BUN and sCr levels were significantly increased after Mel and CA co-exposure. Taken together, significant increase in KIM-1, NGAL, and calbindin levels were observed in the urine of rats exposed to Mel+CA (63/6.3 or 630/6.3 mg/kg) compared with the corresponding control group. Histological analysis revealed epithelial degeneration and necrotic cell death in the proximal tubules of the kidney after co-exposure to Mel+CA (63/6.3 or 630/6.3 mg/kg). Our data suggest that Mel-mediated renal toxicity may be influenced by CA concentrations in Mel-contaminated milk or foods.

  • Objective : The present experiments were designed to study on the immune-enhancing effect of Mountain grown ginseng, Mountain cultivated ginseng, and Panax ginseng Method : In order to compare the immune-enhancing effect of moutain grown ginseng, moutain cultivated ginseng and Panax ginseng, the study was done through the forced swimming test (FST), measurement of T helper Th1, Th2 cytokines and fatigue related factors. Result : Moutain grown ginseng and panax ginseng decreased the immobility time in the FST compared to the control. Glucose, blood urea nitrogen (BUN), creatinine, lactate dehydrogenase (LDH) and Total-protein (T-protein) in serum were investigated. The serum achieved from ginseng administered mouse showed higher BUN, T-protein than the control. moutain grown ginseng administered group showed lower LDH than the control group. moutain grown ginseng administered mouse showed higher glucose than the control. Creatinine was same in either experimental or control group. Ginseng-induced cytokine production in human T-cell line, MOLT-4 cells and mouse peritoneal macrophages were compared. Moutain cultivated ginseng (10-4 dilution) and panax ginseng (10-3 dilution) were increased the interferon $IFN-{\gamma}$ production compared with media control (about 1.6-fold P<0.05) at 48 h. Moutain grown ginseng (10-4 dilution) was increased the $IFN-{\gamma}$ and interleukin IL-4 production compared with media control (about l.4-fold for $IFN-{\gamma}$ and 1.6-fold for IL-4 P<0.05) at 48 h. Moutain grown ginseng (10-3 dilution) and moutain cultivated ginseng (10-4 dilution) were increased the turmor necrosis factor $TNF-{\alpha}$ production compared with $rIFN-{\gamma}$ treated cells (about 1.9-fold for $TNF-{\alpha}$ P<0.05), respectively. Moutain cultivated ginseng (10-3 dilution) was increased the IL-12 production compared with $rIFN-{\gamma}$ treated cell (about 1.7-fold for IL-12 P<0.05). Conclusion : These data suggest that three different three kinds of ginseng act on immune responses in different aspects.

  • This study was carried out to assess whether feeding of alcohol-fermented feeds (AFF) affects the nutritional metabolism and growth characteristics of Korean native steers. Ten steers were randomly assigned to one of two treatment groups. The dietary treatments were AFF (50% commercial beef cattle feed+30% alcohol-fermented soybean curd dregs+20% rice straw) and control (80% commercial beef cattle feed+20% rice straw). The change of serum metabolites and growth characteristics were measured every two months during the whole twelve months experimental period and the relationships between serum metabolites and growth characteristics were simultaneously analyzed. Four hours after feeding AFF, serum alcohol concentration reached its peak with a significantly higher value than that after control feeding (11.9 and 4.9 mg/dl, respectively). Serum glucose and inorganic phosphorus (IP) concentrations (63.1 and 8.4 mg/dl, respectively) of steers fed AFF were higher than those (56.6 and 7.0 mg/dl) fed the control diet. In both treatments, the serum glucose concentration rapidly increased when body weight (BW) of the steer reached about 600kg, while IP concentrations were rapidly diminished at that BW. Lower concentrations of both blood urea nitrogen (BUN) and cholesterol were observed in steers fed AFF up to 450 kg of BW. The IP concentration was correlated with concentrations of BUN, cholesterol and glucose in AFF fed cattle but not in the cattle fed control diets. Average daily gain was higher in steers fed AFF than steers fed control, particularly during the growing stage of cattle. These findings indicated a capability of AFF to improve BW gain of Korean native steers by decreased protein degradation as well as increased fat synthesis.

  • 본 연구는 산겨릅나무의 식품학적 가치를 알아보고 기능성식품 소재로서의 이용.개발을 위하여 항산화 및 간 기능 보호효과를 탐색하였다. 항산화성 결과 가운데 총 폴리페놀은 EtOAc fr.에서 함량이 가장 많았고 BuOH fr., EtOH ex., $CHCl_3$ fr., hot water ex., aqueous fr. 순으로 높게 나타났다. 전자공여능은 EtOAc fr.과 BuOH fr.이 ascorbic acid와 유사한 전자공여능을 보였으며 SOD 유사활성능은 $250\;{\mu}g/mL$ 이하의 농도에서는 BuOH fr.이 가장 높게, 그 이상에서는 aqueous fr.에서 가장 높게 나타났다. LPS로 급성 간 손상을 유도한 마우스에서의 BuOH fr.의 간 기능 보호효과에서는 BuOH fr.을 전 처치한 다음 LPS를 투여한 군이 LPS만을 투여한 군보다 혈장 AST와 ALT의 활성은 유의하게 감소 되었으나 BUN의 농도는 유의성이 관찰되지 않았다. 간조직의 형태학적 관찰에서 BuOH fr.을 투여하고 LPS로 급성 간 손상을 유도한 군의 간세포는 염증과 괴사가 나타났지만 LPS군에 비하여 그 정도가 적은 것으로 나타났다.
