  • Atractylodes macrocephala has been used for renal anorexia, gastroenteritis, cold, dyspepsia in Korean folk medicine. Specially aerial parts has been eaten as edible mountain herbs. In order to investigate the efficacy of antioxidant activity the activity guided fractionation and isolation of physiologically active substance were peformed. For the investigation of the active components from Atractylodes macrocephala MeOH extracts of aerial parts of Atractylodes macrocephala Koidzumi L. were suspended with H$_2$O, partitioned by CHCl$_3$. In order to investigate the efficacy of antioxidative activity the activity guided fractionation and isolation of physiologically active substance were peformed. CHCl$_3$, H$_2$O, 30% MeOH, 60% MeOH, MeOH fractions were examined antioxidative activity by DPPH method. It was revealed that 30% MeOH and 60% MeOH fractions have significantly antioxidant activity. From 30% MeOH and 60% MeOH fraction, six flavonoids (7-methoxy-pinocembrin-7-O-${\beta}$-D-glucopyranoside, apige nin-8-C-${\beta}$-D-glucopyranoside, 4'-caffeoyl-luteolin-6-glucopyranoside, luteloin-6-C-${\beta}$-D-glucopyranoside, apigenin-6-C-${\beta}$-D-glucopyranoside, luteolin) and four phenylpropanoids (3-feruloylquinic acid, 4,5-di-O-caffeoylquinic acid, feruloyl acid, 3,5-di-O-caffeoylquinic acid) were isolated. To investigate the antioxidant activities of each compounds, we measured radical scavening activity with DPPH method and anti-lipid peroxidative efficacy on low density lipoprotein (LDL) with TBARS assay. Six compounds (III, IV, V, VI, IX, X) which have antioxidant factor showed significant activities.

  • Purpose: This literature review was performed to assess the effect of raisins on human health. Methods: A review of Medline was conducted using the keywords: 'raisins, raisins and health, raisins and cardiovascular disease (CVD), raisins and cancer, raisins and diabetes, raisins and fiber, raisins and colon health, raisins and antioxidants, raisins and inflammation, raisins and dental caries'. The reference lists from previous review articles on raisins and human health and the California Raisin Marketing Board files were reviewed for additional studies. Results: Raisins have one of the highest polyphenolic content and antioxidant ORAC levels compared to other traditional dried fruits. Many of the polyphenols in raisins are well assimilated and bioavailable. Raisin consumption reduces low density lipoprotein (LDL) cholesterol, blood pressure and blood sugar, when compared to equal caloric carbohydrate snacks and is associated with a reduced risk of CVD. The anti-inflammatory and cancer chemopreventive effects of raisins are mixed. Raisin consumption reduces intestinal transit time and positively affects gut microbiota. Raisins produce sustained energy during long term athletic competitions equal to traditional sports energy gels, shots and jelly beans. Raisins produce a non-cariogenic oral environment and do not fit the American Academy of Pediatrics criteria to be considered a choking hazard. Conclusions: Based on the review of literature, consumption of raisins provide numerous health benefits for promoting general wellness and in the prevention of many chronic diseases including: CVD, type 2 diabetes mellitus (T2DM) gastrointestinal diseases, and dental caries.

  • This study was done to evaluate the effects of a mixture of essential oils and organic acid supplementation on growth performance, blood profiles, leg bone length and intestinal morphology in Ross broilers. A total of 40 Ross 308 broilers ($1140{\pm}80g$) were randomly allocated to 2 groups, a basal diet (CON) and a basal diet + 0.05% $Avi-protect^{(R)}$ (AVI, Mixture of 25% citric, 16.7 sorbic, 1.7% thymol, and 1.0% vanillin), with 20 replicates for every group and 1 chicken per replicate per cage. The broilers were raised in a temperature-controlled room maintained at $24{\pm}1^{\circ}C$ and $50{\pm}5%$ humidity. The body weight (p < 0.05) and weight gain (p < 0.05) of the broilers were increased in the AVI group compared with the CON group. The triglyceride (p < 0.05) and low density lipoprotein (LDL) (p < 0.05) contents were significantly decreased in the AVI group compared with the CON group. There was no significant difference in the leg bone length between the AVI and CON groups (p > 0.05). The villi height (p < 0.05) and goblet cell count (p < 0.05) were significantly increased in the AVI group compared with the CON group. In conclusion, $Avi-protect^{(R)}$ as a feed additive improved the growth performance and lipid metabolism and promoted the development of the intestinal morphology of broilers.

  • In 1971, Dr. Akira Endo succeeded in isolating a cholesterol synthesis inhibitor, compactin. Later, compactin was renamed mevastatin, meaning that it stops the synthesis of mevalonate, which is considered the first statin. However, mevastatin is not commercially released, whereas lovastatin, developed by Alfred Albert of Merk in 1979, was the first commercially developed statin. After the 4S study, the first largescale clinical trial with statins conducted in Scandinavia showed a dramatic secondary preventive effect against cardiovascular disease, and the effectiveness of statins in patients with dyslipidemia was repeatedly demonstrated. Subsequently, many oral drugs that affect blood lipid concentration; statins and ezetimibe aimed at reducing low-density lipoprotein (LDL)) cholesterol; fibrates and omega 3 formulations aimed at reducing triglycerides were widely developed and used in Korea. In this article, we review the results of clinical studies on representative cardiovascular diseases for four types of oral drugs for dyslipidemia, which are currently the most commonly used in Korea.

  • Objectives : We proposed the hypothesis that administering Trigonella foenum-graecum seed extract (TSE) could alleviate menopausal symptoms and osteoporosis resulting from estrogen deficiency. Methods : Ovariectomized (OVX) rats were administered TSE at doses of 300 or 600 mg/kg body weight for 8 weeks, followed by measurement of serum lipid profile and serum bone markers using ELISA kits. Additionally, analysis of related genes in the femur and uterus was performed using Western blot and real-time PCR. Additionally, micro-CT analysis was performed to investigate the protective effect of TSE against bone loss due to oophorectomy. Results : The administration of TSE led to significant reductions in triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL) cholesterol, and glucose levels in the serum of OVX rats. Furthermore, TSE increased estradiol levels in the serum and notably improved the levels of biochemical markers associated with bone metabolism. Additionally, TSE exerted significant regulatory effects on the mRNA levels of alkaline phosphatase (ALP) and receptor activator of nuclear factor kappa-B ligand (RANKL)-genes closely associated with bone metabolism in the femur. TSE also demonstrated pronounced effects on uterine tissue, with improvements observed in gene expression related to estrogen receptors. Conclusion : Our findings confirm the efficacy of TSE in ameliorating menopause symptoms by modulating elements associated with both bone and lipid metabolism in the serum, uterine tissue, and femur of OVX rats. The present findings suggest that TSE may offer potential therapeutic effects for symptoms related to menopause and osteoporosis in females.

  • Objective: A trial was conducted from 11 to 42 d post-hatch to investigate the effectiveness of the supplementation of a multiple-enzyme preparation (Natuzyme Plus) in a wheat-based diet on digesta viscosity, pH and microbial population, villus morphology, feed passage time, nutrient retention, carcass characteristics, blood lipid parameters and growth performance of broiler chickens. Methods: Three hundreds 10-d-old male Ross 308 chicks were allocated to three diets with five replicates of 20 birds per replicate. Dietary treatments were i) a wheat-based diet (W), ii) W+Natuzyme Plus (WN; 500 mg/kg of the diet), and iii) a corn-based diet (C). Results: Birds fed on the C diet had higher average daily gain (ADG, p<0.01), villus height (VH, p<0.01), total tract apparent retention (TTAR) of nitrogen (NT, p<0.01) and ether extract (EE, p<0.01), nitrogen-corrected apparent metabolizable energy ($AME_n$, p<0.05), relative weight (RW, % of body weight) of carcass (p<0.05), blood concentration of triglyceride (TG, on d 40 [p<0.01]), total cholesterol (TC, on d 22 [p<0.05]) and low density lipoprotein (LDL, on d 22 [p<0.01] and 40 [p<0.05]), and also lower feed conversion ratio (FCR, p<0.01), digesta viscosity (p<0.01), count of coliforms (p<0.01) and Escherichia coli (p<0.01) and epithelium thickness (ET, p<0.05) than those fed on the W diet. ADG, FCR, VH, ET, TTAR of NT and EE, RW of carcass, blood concentration of TG (on d 40), TC (on d 22) and LDL (on d 22 and 40) values of the WN diet did not show a significant (p>0.05) difference compared to those of the C diet. Compared to those of the W diet, the WN diet showed the higher count of Lactobacilli and lower count of coliforms (p<0.01) and digesta viscosity (p<0.01). Conclusion: In general, the results of this study showed that Natuzyme Plus supplementation in a wheat-based diet can be appropriate to achieve a comparable growth performance in broiler chickens to those given the C diet probably through improving digesta viscosity, VH, ET, TTAR of NT and EE, $AME_n$, count of Lactobacilli and coliforms.

  • 노루궁뎅이버섯의 자실체가 고지방과 콜레스테롤을 급여한 Sprague Dawley계 암컷 흰쥐의 지질대사와 생리활성에 미치는 영향을 조사하고자 생후 5주령의 흰쥐에 표준 식이를 급여한 정상군(NC군), 표준 식이에 15%의 돈지와 1%의 콜레스테롤을 첨가한 식이를 급여한 고지방 콜레스테롤군(HFC군), 고지방 콜레스테롤 식이에 노루궁뎅이버섯 자실체 분말을 5% 첨가한 군(HFC+HE군) 등 총 3개의 군으로 나누어 6주간 실험을 진행하였다. 실험동물의 체중증가와 식이효율은 HFC군에 비해 HFC+HE군이 유의하게 감소하여 NC군과 유사한 수준을 나타냈다. 식이섭취량은 NC군과 HFC군에 비해 HFC+HE군이 유의하게 낮았다. HFC+HE군의 혈청 총콜레스테롤, LDL-콜레스테롤의 농도는 NC군과 HFC군에 비해 유의하게 낮았고 동맥경화지수(AI)도 NC군과 HFC군에 비해 유의성 있게 낮았다. 그러나 혈청의 중성지방 농도는 NC군에 비해 유의성은 없었으나 HFC군에 비해 유의하게 낮았다. HFC+HE의 혈청 알부민, 크레아티닌, 요산 및 총단백질의 농도는 NC군의 수준을 나타냈다. 혈청의 AST, ALT 및 ALP 활성은 NC군과 유사하였으나 HFC군에 비해 유의하게 낮았다. 실험 5~6주에 배출된 변을 채취하여 총지질과 총콜레스테롤의 양을 분석한 결과 NC군과 HFC군에 비해 변의 총지질과 총콜레스테롤 함량이 유의하게 높아 변으로 배출된 총지질과 총콜레스테롤의 양이 많게 증가한 것으로 나타났다. 따라서 고지방 콜레스테롤식이에 5%의 노루궁뎅이버섯 자실체 분말을 첨가한 식이를 급여한 흰쥐의 체중은 정상군의 수준을 유지하였고, 혈청의 총콜레스테롤, LDL-콜레스테롤 및 중성지질의 농도도 정상군과 유사하게 낮았으며, 동맥경화지수도 낮아 노루궁뎅이버섯이 흰쥐의 지질대사를 정상으로 유지시키는 효과를 나타내는 것으로 사료되었다.
