  • 본 연구는 여름철 γ-aminobutyric(GABA)와 생균제 급여가 산란 종계의 생산성, 계란품질, 혈액 생화학 조성, corticosteron에 미치는 효과를 조사하였다. 24주령의 산란 종계 총 105수를 3개 처리(대조구, GABA, probiotics), 처리당 7반복, 반복당 5수로 설정하여 사양실험을 실시하였다. GABA와 생균제는 배합사료 내 각각 50ppm과 0.1%로 첨가하여, 총 6주간 실험을 실시하였다. 전기간 산란종계의 평균 계란 생산량, 산란량은 대조구보다 생균제 급여 처리구에서 유의적으로 높았으며(P<0.05), FCR은 생균제 급여 처리구에서 낮은 값을 나타내었다(P<0.05). 산란 종계 계란의 난중, 난백고 높이, Haugh units, 난황색, 난각두께, 난각강도에서 처리구간의 유의적인 차이를 보이지 않았다. 또한 모든 혈청 생화학 조성에서 유의적인 차이를 보이지 않았다. 혈청 내 corticosterone 농도는 GABA와 생균제 급여로 인하여 대조구보다 유의적으로 감소하였다(P<0.05). 따라서 GABA와 생균제 급여 시 고온기 산란 종계의 스트레스를 완화시킬 수 있는 것으로 사료되며, 특히 생균제 급여는 계란 생산성 및 산란량 성적을 개선할 수 있는 것으로 나타났다.

  • DMSO (dimethyl sulfoxide)는 친유성 화합물을 용해하는 성질과 뇌혈관장벽(Blood-brain barrier)을 투과하는 화학적 특성으로 인해 근위축성 측삭경화증(amyotrophic lateral sclerosis) 등의 퇴행성 뇌신경질환을 타겟으로 하는 전임상 연구에서 용매로 널리 활용되고 있다. 그러나 DMSO를 활용한 연구 결과에 대하여 본 물질에 대한 생화학적 효과는 간과되고 있다. 본 연구에서는 근위축성 측삭경화증의 질환동물 모델인 SOD1-G93A형질 전환 마우스에 5% DMSO를 장기간 경구 투여하여 질병 표현형에 미치는 영향을 생존기간을 포함하여 신경학적, 기능학적, 조직학적으로 분석하였다. DMSO를 투여한 SOD1-G93A 동물군에서 DMSO 비투여군 보다 생존 기간과, 로타로드와 악력 측정으로 평가한 근육 기능이 유의미하게 증가했고, neurological score 가 감소했다. 반면, DMSO 투여군에서 DMSO 비투여군 대비하여 척수 운동 신경 세포와 신경근접합부가 보존되지 않았다. DMSO 투여는 SOD1-G93A형질 전환 마우스의 운동 신경 세포의 조직학적 영향을 미치지 않았지만, 신경 증상 완화와 생존 기간 등 개선된 마우스의 quality of life을 확인하였다. 본 연구 결과, DMSO를 이용한 퇴행성 뇌 질환 전임상 연구 및 후보 약물 효능 평가 시 DMSO의 생화학적 특성에 대한 종합적인 고려가 필요한 것으로 보인다.

  • 평균 수명과 노인 연령층의 증가에 따른 노인들의 삶의 질적 향상을 위하여 보다 적극적인 건강증진 방안이 요구된다. 이에 본 연구에서는 영양군 마을 주민들 중에서 60세 이상으로 고혈압, 당뇨병, 고지혈증 진단 및 유소견자 중 자원자 32명을 대상으로 2006년 9월 14일에서 2007년 3월 13일까지 6개월 동안 천마복용 전후의 설문조사와 혈액학적 지질성분 변화 양상에 대한 천마의 효과를 살펴 본 결과는 다음과 같다. 조사대상자의 전체 평균 연령은 $65.7{\pm}7.84$세로 남자는 $70.0{\pm}6.24$세, 여자는 $63.3{\pm}7.76$세이었다. 전체 평균키와 몸무게는 각각 $152.5{\pm}28.9\;cm$, $57.6{\pm}10\;kg$이었으며, 남자 노인은 $165.3{\pm}5.86\;cm$461.7{\pm}11.7\;kg$, 여자 노인은 $143.7{\pm}34.9\;cm$$54.4{\pm}8.03\;kg$로 표준 체격보다 작았고 남자 노인에 비해서 여자 노인의 비만도가 다소 높았다. 질병보유상태는 전체 조사대상자의 81.3%로 고혈압, 근골격 질환, 당뇨병, 심장병, 신경통 등을 앓고 있었다. 약물복용 상태는 조사대상자의 53.1%가 현재 복용하고 있는 약물은 없었으며, 한 가지 약물복용은 남녀 각각 18.2%, 38.1%, 두 가지 약물복용은 9.1%, 9.5%로 남자 노인이 여자 노인보다 약물 복용수가 많았다. 조사대상자의 식태도는 남자에 비해서 여자가 채소와 과일의 섭취 빈도수가 높았으나 남녀 모두 육류와 생선의 빈도수가 낮았다. 1회 식사량은 조사대상자의68.8%가 보통수준이었으며 조사대상자의 87.1%가 균형식으로 먹는다고 답하였다. 또한 영양위험도 평가에서는 고위험 영양불량군이 남녀 각각 81.8%, 76.2%로 고위험 영양불량상태인 조사대상자의 비율이 높았다. 조사대상자의 천마복용 전후의 남녀의 혈압, 혈당 및 헤모글로빈의 평균 수치는 모두 정상 범위 내에 있었으며, 천마복용으로 남자의 경우 p<0.05 수준에서 이완기혈압이 증가된 반면에 혈당이 감소되었다. 혈액 내 중성지방, 총콜레스테롤, LDL과 HDL-콜레스테롤 역시 천마복용 전후 남녀의 평균 수치는 모두 정상범위 내에 있었다. 남자의 경우 p<0.05 수준에서 중성지방은 감소된 반면에 HDL-콜레스레롤은 p<0.05 수준에서 천마복용 전에 비하여 복용 후에 증가되는 경향을 보였다. 그러나 동맥경화나 심혈관계 위험 지수에 있어서는 남녀 모두 천마복용으로 유의적으로 호전된 양상을 보였다. 남녀 성별에의한 영향을 통제하고 천마복용의 효과를 분석하기 위하여 공변량 분석을 실시한 결과 천마복용이 최고혈압, 최저혈압, 헤모글로빈, 중성지방, 총콜레스테롤, HDL-콜레스테롤, LDL-콜레스테롤, AI, CRF 그리고 HTR에는 유의적인 영향은 미치지 못하였다. 그러나 천마복용이 p<0.01 수준에서 혈당치와 p<0.05 수준에서 LHR에는 영향을 미친 것으로 나타났다. 본 연구의 제한점으로는 기본적으로 본 연구의 참여 대상자를 자원자 중심으로한 결과 이들 중 56% 정도가 혈당강하제, 고지혈증 및 고혈압 약을 복용하면서 천마를 섭취했다는 한계점 때문에 천마복용 전후 혈압과 혈중 지질성분이 정상 기준치 범위 내에 있었으며, 그 결과 혈당, 혈압 및 지질성분에 대한 뚜렷한 함량 변화가 나타나지 않은 것으로 추측된다. 따라서 앞으로 천마를 이용한 건강기능식품의 생리효과를 검증하기 위한 실험을 수행하고자 할 때는 정상인, 고지혈증 환자, 고혈압 환자, 약물 복용자 및 비복용자 등 각 항목에 대한 정상군과 위험군을 대상으로 한 광범위한 연구가 수행되어야 한다고 본다. 또한 조사대상자의 혈압과 혈중 지질성분에 대하여 천마 이외에 다른 관련 인자가 미치는 효과에 대한 분석도 필요하다고 본다. 그러나 본 연구결과에서 천마의 복용으로 동맥경화나 심혈관계 질환에 관련된 위험지수가 저하된 결과를 통해서 볼 때 심혈관계 질환의 예방이나 치료의 목적을 위해 한의학적으로 사용되고 있는 천마의 심혈관계 질환에 효능이 있는 것으로 여겨지며 천마를 이용한 다양한 건강식품이 개발되어 국민 건강 향상에 이바지할 수 있으리라 기대된다.

  • Nitrogen compounds of Panax ginseng and their biological activities in plant and animal were reviewed. Major nitrogen compounds found in P. ginseng are free amino acids. Water solilble proteins, indouble proteins and peptides. Minor nitrogen compounds are dencichine. Glycolyroteins, amines, alkaloides, methoxy or alkyl pyrazine derivatives, free nucleosides and nucleic acid bases. 4-methyl-i-thiazoltethanol and pyroglutamic acid the contents of total nitrogen and protein in root Increased until 13 years old which was the highest age tinder investigation. Soluble protein content increased with the root weight and was higher in xylem pith than cortex-epidermis indicating the close relation with root growth. Arginine, which covered 58% of total free amino acids, may serve as storage nitrogen. Arginine seems to be changed into proline in rhizome. threonine in stem and again threonine and arginine in leaf. The greater the root weight the higher the polyamine stimulated Polyamine stimlllated the growth of root callus. Physiological roles of other minor nitrogen compounds are unknown although content is relatively high ((1.if) 6.w). Biochemical and pharmacological activities of some nitrogen compounds for animal were more investigated than physiological role there plant itself. Radiation and U.V protective function (heat stable protein). insulin-like activity in lipogenesis and livolysis (adenosine and pyroglutamic acid), depression of blood sugar content (glycopevtide). htmostatic and nellrotoxic activity (dencichine) and, sedative and hypnotic activity (4-methyl-i-thiazoleethanol) are reported. Heat stable protein increased with root age. The traditional quality criteria appear to be well in accordance with biological activities of nitrogen compounds. Chemical studies of nitrogen compounds seem relatively rare, probably due to difficulty of isolation, subsequently the investigations of biological activities are little.

  • Objective: This study was performed to evaluate the effect of isoflavone supplementation on hormone levels, lipid profiles and total antioxidant status in patients with polycystic ovary syndrome. Methods: Total 11 women with polycystic ovary syndrome were supplemented daily with 150mg of isoflavone for 6 months. Blood samples were collected 0, 3, and 6 months after supplement of isoflavone for analysis of LH, FSH, E2, testosterone, free testosterone, SHBG levels, serum lipid profiles, and total antioxidant status (TAS). Results: After 6 months isoflavone supplementation, the hormone levels did not change significantly. Serum lipid profiles did not show any significant change in total cholesterol, LDL-cholesterol, triglyceride, lipoprotein(a), and free fatty acid levels. However, there was significant increase in HDL-cholesterol (p<0.05) for 3 months. Total antioxidant status was increased significantly after isoflavone supplementation for 6 months (p<0.05). Conclusion: Isoflavone supplementation showed positive effects on the HDL-cholesterol and total antioxidant status. it is implicated that isoflavone supplementation will may have a effect on cardiovascular disease in patients with polycystic ovary syndrome.

  • This study was designed to investigate the impact of a 12-week nutrition education program on 32 male industrial workers (average age: $44.5{\pm}3.8$ yrs, work duration period: $20.1{\pm}5.6$ yrs) diagnosed as having dyslipidemia in a medical checkup at their workplace. This program was implemented with a conceptual framework on strengthening self-efficacy for the improvement of the health conditions of the workers. Most of all, the study exhibited benefits in the industrial workers by ameliorating the risk factors associated with dyslipidemia via changes in dietary behaviors, nutritional knowledge, and attitudes, as well as anthropometric and biochemical parameters. After the nutrition education, overall lifestyle, including the ratios of smoking (P<0.05) and drinking (P<0.01), significantly improved. Exactly 65.6% of the subjects reported that their dietary habits changed. Body weight, BMI, percentage of body fat, and waist circumference all significantly decreased (P<0.001). The systolic (P<0.01) as well as diastolic blood pressures (P<0.001) decreased. Moreover, the degree of increase in serum HDL-cholesterol was appreciable (P<0.001), and the atherogenic index also decreased (P<0.01). Further, risk factors related to metabolic syndrome in subjects significantly decreased (P<0.001). The average scores for nutrition knowledge increased from 9.3 to 17.7 points (P<0.001). All of the participants agreed on the need for a nutrition education program at their workplace. Further, it should be pointed out that the participants strongly indicated the need for continuing nutrition intervention.

  • Purpose: The aim of this study was to determine whether school-aged children with Kawasaki disease (KD) have an increased risk for early atherosclerosis. Methods: The study included 98 children. The children were divided into the following groups: group A (n=19), KD with coronary arterial lesions that persisted or regressed; group B (n=49), KD without coronary arterial lesions; and group C (n=30), healthy children. Anthropometric variables and the levels of biochemical markers, including total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A, apolipoprotein B, homocysteine, highsensitivity C-reactive protein (hs-CRP), and brachial artery stiffness using pulse wave velocity were compared among the three groups. Results: There were no significant differences in blood pressure and body index among the three groups. Additionally, there was no sex-specific difference. Moreover, the levels of triglyceride, HDL-C, apolipoprotein A, and hs-CRP did not differ among the three groups. However, the levels of total cholesterol (P =0.018), LDL-C (P =0.0003), and apolipoprotein B (P =0.029) were significantly higher in group A than in group C. Further, the level of homocysteine and the aortic pulse wave velocity were significantly higher in groups A and B than in group C (P=0.0001). Conclusion: School-aged children after KD have high lipid profiles and arterial stiffness indicating an increased risk for early atherosclerosis.

  • Objectives: The aim of this study was to evaluate the effect of a mild cognitive impairment (MCI) management program on traditional Korean medicine in a public health center. Methods: In order to examine the effect of the MCI management program, we investigated MCI patients who participated in the program. MCI patients were treated with Jodeung-san (JDS) or Dangguijagyag-san (DGJYS) for 6 weeks. Mini Mental State Examination-Dementia Screening (MMSE-DS), Geriatric Quality of Life-Dementia (GQOL-D), Geriatric Depression Scale in Korea (GDS-K), and biochemical examination of blood were conducted at intervals of 6 weeks. A satisfaction survey was collected after this program. Results: MMSE-DS mean score increased significantly, by 4.09 (p=0.000) in the JDS group and by 4.15 (p=0.000) in the DGJYS group. GQOL-D mean score also increased significantly, by 5.90 (p=0.000) in the JDS group and by 5.07 (p=0.000) in the DGJYS group. GDS-K mean score decreased significantly, by 10.63 (p=0.000) in the JDS group and by 9.69 (p=0.000) in the DGJYS group. MMSE-DS, GDS-K and GQOL-D scores were not significantly different between the JDS and DGJYS groups. All of the participants were satisfied with the program, and 90% of the participants expressed a high intention to participate in the program again. Conclusions: Both Jodeung-san and Dangguijagyag-san treatment showed improvement on cognitive function, depression and quality of life in this program. Additional studies with more subjects will be required to prove credibility and validity more clearly.

  • Using the method of 'random sampling in typical colonies of the central area of the habitat', 60 Small-tailed Han sheep were obtained in Jining city, Shangdong province. The variations of Small-tailed Han sheep at 12 structural loci encoding blood proteins were detected by several electrophoresis techniques and their gene frequencies were then estimated. The same data of four other sheep populations from Near-sea Mainland in East Asia were cited for the analysis of genetic differentiation. The average heterozygosities of five populations, namely Kharkhorin sheep, Ulaanbaatar sheep, Small-tailed Han sheep, Hu sheep and Cham Tribe sheep were 0.3447, 0.3285, 0.3157, 0.3884 and 0.2300, respectively. The coefficient of gene differentiation among four populations, Kharkhorin sheep, Ulaanbaatar sheep, Small-tailed Han sheep and Hu sheep, was 0.045557, and that between these four breeds and Cham Tribe sheep was 0.088005, indicating that the level of gene differentiation among the former four sheep populations of Mongolian group was comparatively lower than that between Cham Tribe sheep and other four sheep populations. The origin of Cham Tribe sheep deserve further research. The documentary research on the evolution of Small-tailed Han sheep and Hu sheep from Mongolian sheep was further verified by the biochemical experiments in the study. It was reasonably deduced that Hu sheep, Small Tailed Han sheep and Cham Tribe sheep were decreasingly influenced by the bloodline of Mongolian sheep.

  • The present study was designed to assess whether dietary inorganic and organic selenium (Se) could affect antioxidant enzymes, including superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and glutathione-S-transferase (GST), and the level of malondialdehyde (MDA), a marker of lipid peroxidation, in the intestine, serum, liver, and gastrocnemius muscle of Korean native goats. A total of eighteen Korean native goats was allotted into three dietary groups, consisting of basal diet (CON), or basal diet with either 0.25 ppm inorganic (IOSEL) or 0.25 ppm organic Se (ORSEL), and fed the corresponding diets for 5 wks. Growth performance, including body weight and total gain, and blood biochemical profiles, including GSH-Px, were not significantly different between the three dietary groups. Also, the specific activities of SOD, GSH-Px, and GST, and the level of MDA in the intestinal mucosa and liver from goats were not substantially affected by either inorganic Se or organic Se. However, goats fed the diet containing organic Se showed a significant increase in GSH-Px and GST activities in the gastrocnemius muscle compared with those fed the basal diet. In conclusion, increased muscle GSH-Px and GST activities suggest that dietary organic Se may affect, at least in part, the antioxidant defense system in muscle of Korean native goats under the conditions of our feeding regimen.
