  • The purpose of this study was to observe the effects of Cynanchi wilfordii Radix extracts (CRE) on the improvement of the lipid compositions and blood pressure level in spontaneously hypertensive rats (SHR) fed an experimental diet for 5 weeks. The rats were divided into 3 groups: a control group, a 0.5% CRE treated group, and a 1% CRE treated group. Consumption of CRE extract for 5 weeks in SHR significantly suppressed blood pressure rise with aging (p<0.05). After eating the experimental diets, the triglycerides in serum was significantly lower in the CRE group than that in the control group. The fasting glucose levels of the 0.5% and 1% CRE group had a tendency to be lower compared with those of the control group. Total cholesterol, HDL-cholesterol and HTR (HDL-cholesterol/total cholesterol) of the SHR in the 0.5% and 1% CRE diet were significantly increased compared to the control diet. Thus, long term consumption of CRE might be beneficial in lowering high blood pressure and the improvement of lipid metabolism in SHR rats.

  • Twelve pigs were used to investigate the effects of polyclonal antibody candidate against abdominal (AAb) and subcutaneous adipocyte membrane proteins (SAb) on body weight, fecaldigestibility and blood metabolites. When AAb and SAb developed by Choi et al. (2010) were injected to pigs, the numerical increase in BW (body weight) occurred at 4 weeks post-treatment, but BW for an entire period was also increased, indicating that the BW increase may not be affected by the antibodies injection. Antibodies treatment did not affect (P>0.05) fecal digestibility of dry matter, crude protein, crude fat and crude fiber. Fecal digestibility of crude ash for control (no treatment) at 2 weeks decreased, and that for non-immunized serum treatmentgroup at 4 weeks post-treatment increased, respectively (P<0.05). However, fecal digestibility of crude ash for AAb and SAb groups did not significantly change. At 4 weeks after the antibodies treatment, blood urea N concentration for AAb and SAb groups was significantly increased (P<0.05). However, these increases may not be caused by the antibodies treatment because similar pattern in blood urea N concentration occurred before the antibodies treatment. Antibodies treatment did not affect concentration of plasma glucose and triglycerides (P<0.05). Compared with control, concentration of plasma total cholesterol for AAb and SAb groups at 4 weeks post-treatment was significantly (P<0.05) decreased. This may suggest that body fat reduction possibly occurs. In conclusion, the AAb and the SAb developed by Choi et al. (2010) may have safety in nutritional physiological metabolism in pigs. Further study on in vivo fat reduction of the antibodies against abdominal and subcutaneous adipocytes of pigs should be required for fat-reduced pork production.

  • 그람 음성균의 감염에 의한 만성 염증질환인 치주염이 동맥경화를 동반한 허혈성 심장질환 (협심증이나 심근 경색)을 일으킬 수 있는 위험인자로 작용할 수 있다는 보고가 있었다. 그러나, 그 기전에 관해서는 명확하게 알려져 있지 않다. 작용기전의 하나로서, 치주염에 의해 치주조직에서 국소적으로 생긴 염증성 싸이토카인(IL-1${\beta}$, IL-6, $PGE_2$, TNF-${\alpha}$)이 혈행을 따라 이동하여 심혈관에서 동맥경화를 일으킬 수 있다는 가설이 제시되고 있는데, 이 가설을 검증해 보고자 한다. 서울대학교 병원 순환기 내과에 불안정 협심증이나 심근경색으로 입원한 환자 및 과거 이 질환의 병력을 갖고 있거나 검진 목적으로 내원하여 관상동맥 조형술을 받은 환자들 중 동맥경화로 진단받은 사람을 실험군(24명)으로 하고, 동맥경화로 진단받지 않은 사람을 대조군(12명)으로 하였다. 치주질환의 활성도를 나타내는 치은 지수, 치태 지수, 치주낭 깊이, 부착 상실을 측정하였다. Paper strip을 실험대상 치아(Ramfjord's teeth)들 중에서 가장 깊은 치주낭을 가진 두 개의 치아를 택하여 각 치아의 가장 깊은 치주낭에 30초간 삽입한 후 밀폐된 plastic tube에 넣고 ELISA kit를 이용하여 IL-1${\beta}$, IL-6, TNF-${\alpha}$, $PGE_2$의 농도를 측정하였다. 환자의 plasma에서도 동일한 싸이토카인의 농도를 측정하였다. 설문조사를 통해 동맥경화의 위험 인자로 간주되어온 고혈압, 당뇨, 가족력, 심근경색이나 협심증의 기왕력, 흡연의 유무를 기록하였다. 혈액검사를 하여 total cholesterol, triglycerides, LDL cholesterol, HDL cholesterol, WBC, CRP (C-reactive protein)의 농도를 측정하였다. 치주조직에 대한 임상 검사 결과 치은의 염증상태를 나타나는 지표인 치은 지수에서만 실험군이 대조군에 비해 유의할 정도 (p=0.0174)로 높게 나타났고, 만성적인 염증의 결과로 인한 치조골의 사실 정도를 나타내는 치주낭 깊이나 부착 상실에서는 유의할 만한 차이를 보이지 않았다. 치주낭에서 측정한 염증성 싸이토카인 중 IL-1${\beta}$, $PGE_2$가 실험군에서 유의할 만한 차이 (p=0.005, 0.022)를 보이며, 더 높은 농도로 나타났고, TNF-${\alpha}$는 대조군에서 유의성 있게 (p=0.009) 높게 나타났다. 그러나, plasma의 싸이토카인이나, serum lipid/lipoprotein, C-reactive Protein, WBC는 유의할 만한 차이를 보이지 않았다. 또한 치은열구액내의 싸이토카인과 이에 상흥하는 싸이토카인 간에 상관관계는 관찰되지 않았다. 다변량 로지스틱 회귀분석 결과, 치은열구액내의 IL-1${\beta}$와 TNF-${\alpha}$ 만이 동맥경화와 유의성 있는 관련성을 보였고, 특히 IL-1${\beta}$와 교차비는 273으로 상당한 관련성을 보여주었다. 결론적으로, 치주조직에서 국소적으로 생긴 염증성 싸이토카인이 그대로 혈행으로 이동하여 혈장내의 싸이토카인 농도를 높이는 것은 아니다. 그러나, 치주염으로 인해 치은열구내액내에 국소적으로 증가된 염증성 싸이토카인은 동맥경화와 상당한 관련성을 가진다.

  • The purpose of this study was to investigate the effects of a 12 week weight control program, which included nutrition education and regular physical fitness, on body weight, degree of obesity, BMI, and lowering of blood lipids in 16 obese male elementary school students. Changes in waist and hip circumferences and their ratios were measured at the conclusion of the 12 week program conducted from September 9 to November 25, 2005. Body weight after 12 weeks on the program slightly reduced from 55.4${\pm}$10.9 kg to 54.4${\pm}$9.7 kg. Degree of obesity and BMI decreased from 121.3${\pm}$8.1%, and 25.9${\pm}$3.3 to 120.0${\pm}$8.2% and, 25.6${\pm}$2.7, respectively. Body fat percentage decreased slightly from 38.3${\pm}$4.7% to 37.9${\pm}$5.2%. Waist to hip ratio did not change after 12 weeks. There were slight changes in weight of body fat and lean body mass from 22.12${\pm}$6.53 kg and 34.56${\pm}$4.75 kg to 21.68${\pm}$6.05 kg and 34.70${\pm}$4.54 kg, respectively. Also, after 12 weeks on the weight control program, body, waist, and hip circumferences decreased. However, there were no significant differences among the blood lipid components, including triglycerides, total cholesterol, and HDL-cholesterol. Finally, body weight, degree of obesity, BMI, and body fat showed more significant correlations to waist, hip circumference and their ratio than to blood lipid levels.

  • This study was conducted to evaluate the anti-hypertensive effect of Lactobacillus sp. isolated from Kimchi by examining its effects on renal angiotensin-converting enzyme (ACE) inhibitory activity, lipid components and blood pressure using the spontaneously hypertensive rat (SHR) system. Most Lactobacillus sp. extracts (lysozyme, sonication and ethyl acetate extracts) showed higher capacities for the inhibition of ACE activity than those of cultured media. Particularly, LG 7, 8 and 42 of Lactobacillus sp. showed the strongest inhibitory activity among the Lactobacillus sp. extracts. The concentrations of total cholesterol and triglycerides in the serum were lower in the Lactobacillus sp. administration groups than in the control group, but these differences were not significant. The HDL-cholesterol concentrations of the LG 42 administration groups (IX, X) were significantly higher than that of the control group. At 4 weeks, the systolic blood pressure (SBP) in the LG 42 Lactobacillus sp. ($1{\times}10^9$ cfu/mL) group (XI) was about 27% lower than that of the control group (V). No adverse effects were observed on the liver and there was no difference in the aspartate aminotransferase (AST) and alanine aminotransferase (ALT) values among groups. The results of this study suggest that long term consumption of LG 42 Lactobacillus sp. may be beneficial to the prevention of high blood pressure.

  • This study was conducted to compare the egg productivity, egg quality, and blood characteristics of laying hens with different laying rates, and the frequency and cumulative duration of the sitting behavior observed before laying was investigated. Twelve 45-week-old Hy-Line Brown laying hens were randomly assigned to two treatment groups with three replicates. Treatment groups were classified as layers laying over 80%(high egg performance layers; HEP) and layers laying below 50%(poor egg performance layers; PEP). The experiment lasted 4 weeks. HEP showed higher hen-house egg production ratio and egg mass and lower feed conversion ratio(FCR) (P<0.05) compared with PEP, although egg weight was higher in PEP (P<0.05). In terms of egg quality, PEP showed differences in eggshell quality (eggshell color, eggshell thickness, and eggshell weight) (P<0.05). Additionally, HEP showed high triglycerides(TG), and PEP showed high alanine transaminase(ALT) level (P<0.05) in serum collected in the morning. In the afternoon, the HEP showed higher lactate dehydrogenase(LDH) levels (P<0.05). No differences in the Ca: P ratio were observed between layers with different laying rates. One hour before egg laying, HEP exhibited sitting behavior 4 times on average, each lasting 25 minutes. In conclusion, egg production and quality differ between HEP and PEP, and HEP showed frequent sitting behavior before egg laying. However, additional research is necessary to explore approaches other than specific behavioral observation to distinguish poor layers in the flock for application in farms.
