  • Platelets serve many biological functions, including a major role in the haemostatic process. But platelets also play a crucial role in the formation of arterial thrombosis, arteriosclerosis and other pathologic processes. Thus, there have been many studies to develop new antiplatelet agents from foods and plants for decades. Inthis study, inhibitory effects of the oriental onion (Allium fistulosum) on platelet aggregation were investigated using platelet rich plasma (PRP). Water extracts of oriental onion was separated into two fractions (Fraction I and Fraction II) by Sephadex G-150 column. Platelet aggregations were inhibited by total water extracts as well as Fraction I and II. IC50 value of Fraction I was much lower than that of Fraction II. Inhibitory effects of total water extracts of oriental onion on ATP release by PRP were also observed.

  • The objective of this research was to determine controlling effects on rice blast (Pyricularia oryzae) in rice plants by using plant extracts from different extraction methods (water, boiling water, fermentation, and ethanol) from 38 agricultural materials of traditional agriculture. Rice blast was completely suppressed by 3% ethanol extracts in Rheum palmatum roots, and suppressed 97% and 77% by 10% ethanol extracts in onion bulb and pine tree leaves, respectively in a laboratory test. However, other agricultural materials showed low effect on suppression of rice blast. Additionally, in a seedling test, rice injury of two cultivars (Ilmibyeo and Hopyoungbyeo) against rice blast was reduced 40-71%, 29-63%, and 23-63% by 5 and 10% ethanol extracts in Rheum palmatum roots, onion bulb, and pine tree leaves, respectively, compared with non-treated controls. Rice injury of two cultivars (Ilmibyeo and Hopyoungbyeo) against rice blast was reduced by 21-55%, 23-46%, and 5-39% in response to Rheum palmatum roots, onion bulb, and pine tree leaf applications at 100, 200 and $400g/m^2$ at 0 day after seeding, respectively, compared with non-treated controls. Rice plants did not show any leaf injuries and growth reduction after treatments of the Rheum palmatum roots, onion bulb, and pine tree leaf extracts or soil application. Thus, the above materials may be used for controlling rice blast in organically produced rice fields.

  • The purpose of this study was to test the overall preference of Saury fishmeat nuggets. In order to remove off-flavor of Saury and to improve the sensory properties of Saury fishmeat nuggets, different concentrations of vegetables (onion, 0-20%), different types of spices (ginger powder, white pepper powder, garlic powder) and different types of vegetables (onion & hot pepper, onion & pimento, mushroom & hot pepper, and mushroom & pimento) were added and the sensory properties were evaluated. Different types of herbs (Anthemis nobillis, Rosemarinus offcinalis L) and oriental herb (Angelica gigas Nakai, Acanthopanax sessiliflorus Seed) extracts were included as well to preserve the antioxidants in the nuggets after reheating. The main ingredients included saury mince, mild pizza cheese, hydrated textured soy protein, and egg white powder. The samples were molded (dia. 4.5 cm, thickness 1.5 cm, 20 g), lightly battered and fried for 2 min (2 time) at $160^{\circ}C$. The samples were then frozen, reheated ($150^{\circ}C$, 20 min) and subjected to a sensory evaluation. In the sensory evaluation, Saury nuggets made with a vegetable concentration of 15% had the highest flavor, taste, and overall preference (V5). In addition, Saury nuggets made with 1 g of ginger powder and garlic powder scored the highest in the preference test (S2). Saury nuggets made with onion and pepper had the highest score in the preference test relative to all the other tested vegetables (SV1). Finally, in terms of the herb and oriental herb extracts, the nuggets made with the condensed extracts at a 1/20 ratio of Acanthopanax sessiliflorus Seed (AS) scored the highest in the preference test, since AS had the lowest off-flavor taste.

  • The aim of this study is to investigate the effects of onion and acanthopanax senticosus on body weight change, serum total cholesterol, HDL cholesterol, LDL cholesterol, triglyceride, free fatty acid, total lipid, phospholipid level, renal and liver function test, and CBC in obese rats and mice. Obese rats induced by high-fat fed are medicated for 7 weeks. Rats are divided into four groups depending on the medication; normal group (general-fat fed and no-medication), control group (high-fat fed and no medication), sample A group (high-fat fed and onion 100% extracted medication), sample B group (high-fat fed and onion 50% & acanthopanax senticosus 50% extracted medication), sample C group (high-fat fed and red onion 50% & acanthopanax senticosus 50% extracted medication). After medication, obesity related index, renal and liver function test, and CBC are analysed. There are significant statistical differences among control group and all experimental groups for the body weight change. There are significant statistical differences among control groups and all experimental groups for the total cholesterol, HDL cholesterol, LDL cholesterol, triglyceride level, free fatty acid, and phospholipid level. These results suggest that medications of onion and acanthopanax senticosus extracted products are effective for the treatment of obesity. Especially, onion 100% extracted product is more effective than the others.

  • Objectives : Onion (AlliumcepaL.) is one of the richest sources of flavonoids in human diet. In this study, we studied the effects of onion peel water extract (OPE) on the blood lipid profiles and glucose in rats. Methods : The experimental groups were divided with 5 groups (n = 6) of SD rats: normal diet + distilled water (NC), high-fat diet + Quercetin (PC), high-fat diet + onion peel water extract 4 mg/kg (OPE-4), high-fat diet + onion peel water extract 20 mg/kg (OPE-20), high-fat diet + onion peel water extract 100 mg/kg (OPE-100). Results : The liver fat showed significantly lower weights and size in the OPE-100 group as compared with NC group (p<0.05), The epididymal fat and retroperitoneal fat showed significantly lower weights and sizes in the OPE-4 and OPE-20 group as compared with NC group (p<0.05). The serum levels of total cholesterol, LDL cholesterol and triglyceride were significantly lower in the OPE-4 and OPE-20 group as compared with NC group (p<0.05). The OPE-4 and OPE-20 group showed higher HDL cholesterol concentration than NC group (p<0.05). Atherogenic index of OPE-4 and OPE-20 group was significantly lower in as compared with NC group (p<0.05). The serum levels of glucose significantly lower in the OPE-20 group as compared with NC group (p<0.05). Conclusions : In these results, we suggests that onion peel water extracts supplementation can reduces the serum lipid components and improves the lipid metabolism in hyperlipidemic SD rat induced with a high-fat diet.

  • The purpose of this study was to investigate the appropriate water content in high omega-3 fatty acid Saury nuggets for the desirable texture. The approach was made with adding water and onion at various levels (0~20%). The main ingredients of the nuggets included saury mince, mild pizza cheese, and hydrated textured soy protein concentrate. The formulated products were molded (dia. 4.5, thickness 1.5 cm, 20 g), lightly battered, and flash fried for 4 min. at $160^{\circ}C$, and then frozen until tested. The frozen nuggets were cooked at $165^{\circ}C$ and subjected to sensory evaluations, texture analysis, and water content analysis during warming (0~60 min), as well as assessments of acid, peroxide, and TBA values (during 10 days of storage at $24^{\circ}C$). In the sensory evaluation, preference for texture was highest in the nuggets made with a 15% onion level. The hardness of the nuggets increased with increasing onion level. Moisture content was highest in the nuggets made with a 20% water level. Changes in hardness during warming (0~60 min) of Saury nuggets containing various water and onion levels increased in nuggets made with the 20% water level. The acid, peroxide, and TBA values of the Saury nuggets made with herbs and oriental herbal extracts decreased up to 10 days of storage.

  • 본 연구에서는 파의 항염증 효과를 밝히고 그 생화학적 기전 해석을 위해 LPS로 활성화된 BV2 microglia를 이용하여 iNOS, COX-2 및 염증성 cytokine의 발현 및 그 산물에 미치는 파 추출물의 영향을 조사하였다. 그 결과 파 추출물은 LPS 처리에 의한 BV2 세포의 iNOS의 발현을 전사 및 번역 수준에서 처리 농도 의존적으로 억제시켰으며, 특히 파 전체 에탄올 추출물(EEWA)의 효과가 가장 탁월하였다. LPS로 유도한 COX-2의 mRNA 및 단백질 발현 역시 파 추출물 처리에 의하여 감소되었으며 뿌리 에탄올 추출물(EERA) 처리군에서 가장 현저한 억제가 관찰되었다. 아울러 염증 반응의 또 다른 주요인자인 염증성 cytokine들(TNF-${\alpha}$, IL-$1{\beta}$ 및 IL-6)의 mRNA 변화를 조사한 결과 파 추출물이 대체적으로 이들 cytokine의 발현을 억제하는 경향을 보였으며, 최종산물인 TNF-${\alpha}$와 IL-6의 생성량 역시 유의한 수준은 아니었으나 감소하는 경향을 보였다. 본 연구의 결과는 파의 추출물은 iNOS, COX-2 및 염증성 cytokine의 발현을 조절함으로서 신경염증 반응을 효과적으로 억제하며, 향후 지속적인 연구가 필요하지만 신경 보호 작용에 탁월한 효능이 있음을 보여주는 것으로 생각된다.
