Objectives We aimed to find out the improvement effect of Baekhogainsam-tang (Baihu Jia Renshen-tang, BIT) on metabolic syndrome and alteration of microbiota and gene expression. Methods We used male C57BI/6 mice and randomly assigned them into three groups. Normal control group was fed 10% kcal% fat diet, high-fat diet (HFD) group was fed 45% kcal% fat diet and 10% fructose water. BIT group was fed same diet as HFD group and treated by BIT for once daily, 6 days per week, total 8 weeks. We measured their body weight and food intake every week and performed oral glucose tolerance test 1 week before the end of the study. Then we collected the blood sample to measure triglyceride, total cholesterol, high-density lipoprotein cholesterol, insulin, and hemoglobin A1c. We harvested tissue of liver, muscle, fat, and large intestine for quantitative polymerase chain reaction (qPCR) and histopathological examination. Fresh fecal samples were collected from each animal to verify alterations of gut microbiota and we used RNA from liver tissue for microarray analysis. Results The body weight and fat weight of BIT group were reduced compared to HFD group. The qPCR markers usually up-regulated in metabolic syndrome were decreased in BIT group. Bacteroides were higher in BIT group than other groups. There were also differences in gene expressions between two groups such as Cyp3a11 and Scd1. Conclusions We could find out BIT can ameliorate metabolic syndrome and suggest its effect is related to gut microbiota composition and gene expression pattern.

서구화된 식습관의 변화와 편리한 생활에 따른 운동 부족, 유전적 요인, 심리적 요인 등이 복잡하게 얽히면서 비만이 꾸준히 증가하는 추세이다. 한편, 감귤류에는 carotenoid, coumarin, phenylpropanoid, limonoid 등 60여종의 생리활성 물질이 함유되어 있으며 감귤박에는 bioflavonoid, carotenoid, hesperidin, terpenes 등이 풍부하게 함유되어 있다. 감귤박은 항산화 효과, 고혈압 예방, 혈중 LDL 콜레스테롤 함량 감소 효과 등이 있음이 보고되어 있고 최근 들어 감귤박의 비만을 억제하는 효능이 밝혀져 항비만 효과가 입증되었다. 본 연구에서는 고지방식으로 유도한 비만모델 ICR 생쥐에서 Aspergillus oryzae로 발효한 감귤박의 증강된 항비만 효과를 확인하고자 하였다. 항비만 효과를 확인하기 위해 생쥐의 체중변화와 조직의 무게변화를 관찰하였고, 그룹별 혈청 지질 농도, 간 지질농도 및 동맥경화지수를 관찰하였다. 그 결과, 고지방식이 투여군(HFD)에 비해 감귤박 추출물 투여군(CP)과 감귤박 발효 추출물 투여군(CPA)은 체중 증가량과 증체율이 감소하였고, 혈청과 간의 total cholesterol (TG), triglyceride (TC) 함량이 현저히 감소하였다. 한편, 유익한 cholesterol로 알려진 high density lipoprotein cholesterol (HDL-C) 함량은 일반식이 투여군(NFD)과 CPA 투여군이 비슷하였다. CP 투여군과 CPA 투여군의 조직 무게에서도 HFD 투여군보다 감소하여, 전체적으로 CPA 투여군에서 특히 유의적으로 감소하였다.

본 연구에서는 한국인이 평소 섭취하는 일반식사와 유사한 수준의 당부하량을 가진 high GL 식사와 당부하량이 낮게 설계된 low GL 식사를 섭취한 후 체중, 체지방, 혈압 및 혈액 내 생활습관병 위험 지표 등의 변화를 분석 및 비교하였다. 20대 성인남녀를 대상으로 체중 감량을 위해 wash-out 기간인 중간 2주를 제외하고 개인 필요 열량의 30%를 줄인 low GL 식사와 high GL 식사를 각 2주간 제공하였다. Low GL 식사와 high GL 식사의 효과를 비교한 결과 low GL 식사가 high GL 식사에 비해 체중 (p < 0.001), 체지방량 (p = 0.024), 체질량지수 (p < 0.001)에서 유의적으로 감소량이 더 컸다. 하지만 혈압, 혈액 내 비만 질환 위험 지표에서는 유의한 차이가 없었다. Low GL 식사의 전·후를 비교한 결과 체중, 체지방량, 체질량지수, 체지방률, 이완기 혈압, 중성지방, 총콜레스테롤, HDL-콜레스테롤, LDL-콜레스테롤, 공복혈당, C-peptide HOMA 지수가, high GL 식사에서는 체중, 체지방량, 체질량지수, 총콜레스테롤, HDL-콜레스테롤, 공복혈당, C-peptide, C-peptide HOMA 지수에서 각 식사 전보다 후에 유의적으로 감소되었다. 또한 실험 식사 섭취 전과 섭취 후를 비교한 결과 체중, 체지방량, 체질량지수, 체지방률, 혈압 (수축기, 이완기), 총콜레스테롤, HDL-콜레스테롤, LDL-콜레스테롤, 공복혈당, 당화혈색소, C-peptide, C-peptide HOMA 지수가 모두 유의적으로 감소되었다. 본 연구 결과 체중감량 및 생활습관병 위험을 줄이기 위해서는 단순히 섭취 열량을 낮추기보다는 열량과 함께 당부하량을 고려하여 섭취하는 것이 체중을 감소시키는 데에 더 효과적일 것으로 사료된다.

The study was conducted to evaluate the effects of trivalent chromium from different sources on growth, carcass composition, and serum parameters in finishing pigs. Ninety-six crossbred pigs with an initial average body weight of 65.57${\pm}$1.05 kg were blocked by body weight and randomly assigned to four treatments with three replicates. Pigs were offered one of four diets including a control diet or the control diet supplemented with 200 ${\mu}g/kg$ chromium from either chromium chloride ($CrCl_{3}$), chromium picolinate (CrPic) or chromium nanocomposite (CrNano) for 40 days. After completion of the feeding trial, eight pigs from each treatment were selected to collect blood samples, and slaughtered to measure carcass composition. The results showed that supplemental chromium had no significant effect on growth performance, while CrNano increased carcass lean proportion and loin Longissimus muscle area (p<0.05), and decreased carcass fat proportion and 10th rib backfat depth (p<0.05). CrPic supplementation also resulted in lower fat proportion and larger Longissimus muscle area (p<0.05). The addition of Cr from CrNano or CrPic decreased serum glucose (p<0.05) and increased concentrations of total protein and free fat acid in serum (p<0.05). Serum urea nitrogen, triglyceride and cholesterol were decreased (p<0.05), and serum high density lipoprotein and lipase activity were increased (p<0.05) with the supplementation of CrNano. Serum insulin was decreased (p<0.05) by supplemental Cr from CrNano or CrPic, and serum insulin-like growth factor I was increased significantly in the CrNano treated group. These results suggest that chromium nanocomposite has higher efficacy on carcass composition in pigs compared to the traditional chromium sources.

This study investigated the effect of Bacillus subtilis (B. subtilis) natto on meat quality and skatole in TOPIGS pigs. Sixty TOPIGS pigs were randomly assigned to 3 groups (including 5 pens per group, with 4 pigs in each pen) and fed with basic diet (control group), basic diet plus 0.1% B. subtilis natto (B group), and basic diet plus 0.1% B. subtilis natto plus 0.1% B. coagulans (BB group), respectively. All pigs were sacrificed at 100 kg. Growth performance, meat quality, serum parameters and oxidation status in the three groups were assessed and compared. Most parameters regarding growth performance and meat quality were not significantly different among the three groups. However, compared with the control group, meat $pH_{24}$, fat and feces skatole and the content of Escherichia coli (E. Coli), Clostridium, $NH_3$-N were significantly reduced in the B and BB groups, while serum total cholesterol, high density lipoprotein, the levels of liver P450, CYP2A6, and CYP2E1, total antioxidant capability (T-AOC) and glutathione peroxidase and Lactobacilli in feces were significantly increased in the B and BB groups. Further, the combined supplementation of B. subtilis natto and B. coagulans showed more significant effects on the parameters above compared with B. subtilis, and Clostridium, and $NH_3$-N. Our results indicate that the supplementation of pig feed with B. subtilis natto significantly improves meat quality and flavor, while its combination with B. coagulans enhanced these effects.

A total of 16 growing pigs (Landrace${\times}$Yorkshire${\times}$Duroc, average weight $71{\pm}2kg$) were used in this experiment for 24 days to determine the effect of replacing ground corn with barley varieties on growth performance, nutrient digestibility, and blood metabolites. Each pig was housed individually in a metabolic cage with a nipple waterer and feeder. Four dietary treatments included control (a corn and soybean meal-based diet) and 3 barley varieties (Youngyang, Wooho, or Yuyeon barley replacing 40% of ground corn). Growth performance and nutrient digestibility were not affected by replacement of 40% of ground corn with one of the three barley varieties (p > 0.05), but final body weight was. As for blood characteristics, pig treated with all of the barley treatments had no effect (p > 0.05) on total protein, albumin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LD), and glucose in comparison with control; however, there was a difference in high density lipoprotein (HDL)-cholesterol levels between the control and all of the barley replaced treatment groups (p < 0.05). In conclusion, in spite of statistically significant differences, each of the three barley varieties is a suitable substitute for ground corn in the diet of growing and fattening pigs without adverse effects on growth performance, nutrient digestibility, and blood characteristics.
