  • 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.

  • It is well known the functional foods are very useful to prevent serious diseases and promote health. Therefore, they are often called as nutraceuticals, designer foods, and pharmafoods, etc. Most of foods have diverse functions because they provide nutrients, energies and fibrinoid materials. When foods are taken in the body, they promote the biological defense system against diseases through the supply of the essential or healthy materials to human being's organs. The mode of action and functional foods in human body have not been clarified yet. Antioxidant is known as one of the therapeutic aids which can be reduced pesticide poisoning. Onion has a strong antioxidant effect. This study was carried out to elucidate an antioxidant function of onion by determination of superoxide dismutase in liver, lung, serum of male rat administered by intraperitonial injection of 0, 2, $4\;mg\;kg^{-1}$ cblorpyrifos after administrated orally with onion for 6 weeks. Damage of liver and kidney was also investigated by biochemical analysis of serum(AST, ALT, BUN/Creatine ratio). SOD(superoxide dismutase) activity of onion-administrated group is higher than control group. In liver and lung, SOD activity of onion+cblorpyrifos administrated group is higher than only chlorpyrifos administrated group. BUN/Creatinine ratio of onion+chlorpyrifos administrated group was decreased compared with only chlorpyrifos-administrated group.

  • In this study, in order to confirm the ameliorative effects of onion (Allium cepa L.) flesh and peel on amyloidbeta (Aβ)-induced cognitive dysfunction, we evaluated their in vitro neuroprotection and in vivo cognitive functions. As the result of in vitro neuroprotection, the protective effect of the ethyl acetate fraction of onion flesh (EOF) on Aβ-induced cytotoxicity was similar to that of the ethyl acetate fraction of onion peel (EOP). In the behavioral tests, the EOF and EOP effectively improved the Aβ-induced learning and memory impairments. For this reason, it could be concluded that the EOF and EOP improved the antioxidant activities (superoxide dismutase, oxidized glutathione/total glutathione, and malondialdehyde) in brain tissue. In addition, the EOF and EOP effectively activated mitochondrial functions by protecting the mitochondrial membrane potential, ATP, mitochondria-mediated protein (BAX and cytochrome c), and caspase 3/7 activities. The EOF and EOP also improved the cholinergic system (acetylcholinesterase and acetylcholine). Therefore, we suggest that onion could be used for management of Aβ-induced cognitive dysfunction.

  • The intention of this study is to apprehend the con. tents and methods of herb remedies that are commonly conducted when there are health-problem cases of ENT, eyes, teeth and skin. Methods of this study are divided into two stages : 1) For a period of six months from December 1994 to June 1995, some 40 persons who are believed to be well versed with herb remedies have been randomly chosen, and we made a survey on herb remedies by symptoms: and 2) we have endeavored to make their grounds evident through the studies on literatures with the focus on the basic data collected. Their results are as follows: 1) When one feels a pain in ears, such herb remedies are employed as pouring the vapor into ears, which is made by steaming Alaska pollack, or as applying or wiping with the juices of radish or the ginkgo, or' alum. Applying the radish juice is effective for sterilization and fever removal: and applying the ginkgo juice is effective for cleanliness. But, plastering alum, sesame oil or castor oil, or pouring the vapor of Alaska pollack into ears are perhaps effective but do not have any pharmacologic grounds. 2) When one bleeds at the nose, such kinds of herb remedies are applied as stimulating nose or head with cold water, pressing nose or ridge of nose, or filling up nares with mashed mugworts. In addition, they have utilized garlic or leeks. Such methods as stimulating with cold water or just pressing nose and ridge of nose is based on reasonable grounds, i.e. vasoconstriction and vascular compression ; and applying mashed garlic on the sole of foot is good for the circulation of Qui ; and the use of mugworts and leeks is based upon the pharmacological function of hemostasis. 3) When one feels a sore throat such kinds of herb remedies are employed as gargling or rinsing throat with brine, drinking hot gruel or water, or drinking the juice of mugwort, radish, ginger or Chinese quince. Gargling with brine or drinking the juice of mugwort, radish or ginger is based upon the pharmacological function of pain alleviation, fever removal, and detoxication. 4) When a boil is formed in mouth, such herb remedies are applied as spreading honey, brine or alum water, and taking gall nut, Chinese matrimony vine, lotus root, etc, for drugs. Spreading honey, brine or water that is made by infusing gallnut, Chinese matrimony vine, lotus root is based upon such functions as hematosis, astriction, antibacterial, and antiphlogistic, Alum, eggplant and licorice are said to be effective, but their pharmacological effects have no grounds. 5) When one has conjunctivitis such herb remedies are commonly applied as irrigation with brine and dropping breast milk in eyes. Moreover, such other drugs are used as plantain. shepherd's purse, and purslane, etc. The use of brine, breast milk, plantain, shepherd's purse and purslane is based upon such functions as sterilization, antiphlogistic, disinfection and pain relieving. Eriocaulon sieboldianum, bean stem, bean pod and narcissus leaves are said to be effective, but their pharmacological action have no basis. When one has a stye, such herb remedies are applied as extracting eyelashes, stimulating by a massage of middle finger, third finger or big toe, as well as sear ing with a heated bamboo comb that is fine-toothed. Other than these, plantain and nightshade's nuts are used as drugs for it. Extracting eyelashes corresponds with exclusing suppurative node and draining the stye of pus ; and the use of plantain is based upon disinfection: and nightshade's nuts are said to be effective, however, their pharmacological action has no grounds. 6) For a treatment of toothache, such herb remedies are commonly employed as rinsing mouth with brine and holding cold water or gasoline in the mouth ; and as the drugs that are believed to be effective have been Welsh onion, ginger and castor-oil, plant, etc. The use of Welsh onion is based upon pain killing, antiinflammatory actions, and the use of ginger is based upon detoxication and disinfection ; and seeds of castor-oil plants are said to be effective, but they have no pharmacological basis. 7) When one has hives, such herb remedies are commonly applied as rubbing burned straw in affected parts, exposing to its smoke, rubbing with salt, sweeping down with a broom, and spreading and drinking boiled water of trifoliate orange. The use of cassia tora seeds, walnut, aloe and radish is said to be effective. The use of cassia tor a seeds has the functions of intestinal order, anti-paralysis, etc. The use of walnut has resulted in an increase of blood by invigorating spirits ; and the use of aloe is based upon disinfection, antibiotic, anti-salt, antihistamine and detoxication action. But, the effects of radish juice and straw's smoke have no pharmacological grounds. 8) When one gets a boil, such herb remedies are commonly used as applying a plaster, paste of flour mixed with yolk, soy sauce or honey, as well as spreading pounded elm tree. Other remedies that have been said to be effective are ; heating with mugwort, brine, wild rocambole, aloe, onion, squid's bone, etc. The use of mugwort is based upon pain killing, astringent antiinflammatory and tranquility. Wild rocambole is based upon the generation and maintenance functions of cell-joining textures ; elm tree upon antiphlogistic ; aloe upon fever removal and antiphlogistic ; onion on pain killing, fever removal, antiphlogistic and tranquility ; squid's bone on astriction: and brine or vinegar on sterilization. Pine resin and gardenia seed are said to be effective, but they have no pharmacological basis. 9) When one cuts his skin, such herb remedies are commonly employed as spreading mugwort's juice or squid's bone powder, or pressing the wounds. In addition, kalopanax, onion and fine soil are employed. The use of mugwort, kalopanax and squid's bone is based upon such functions as hemostasis, sedation, pain killing, antibacterial ; and fine soil is said to be effective, but it has no pharmacological basis. 10) When one suffers from whitlow, such herb remedies are commonly utilized as heating with boiled soy sauce, spreading soybean paste, or dipping into eggs, etc. Other drugs that have been employed are onion root, brine, eggplant, potato, loach, etc. The use of onion is based upon pain killing and antiphlogistic functions ; and that of brine upon antiphlogistic function. The use of soy sauce or soybean paste, fomentation, eggplant, potato and loach is said to be effective, but it has no pharmacblogic ground. 11) For the treatment of frostbite, such herb remedies are commonly used as dipping the affected part into frozen soybean sack, using boiled water of eggplant stem, garlic caulis, onion, hot pepper, caulis. Onion is based upon antiphlogistic and tranquility actions garlic upon disintection, metabolic exacerbation, tonic and aphrodisiac actions and the use of eggplant and hot pepper is based upon help blood circulation, dissolution and excretion of waste matters in vein. 12) For the treatment of burn, such herb remedies or drugs are commonly used as cleansing with Korean gin, spreading eggs, cleansing with cold water and soap water ; and as brine, cactus, moss, soybean paste, oil, etc. The cleansing with Korean gin, cold water, soap water, brine, vinegar is based upon cleaning and sterilizing functions ; and the use of cucumber is based upon nu. trition provision, and strengthening of resisting power by adjustment of metabolism. The use of potato, cactus, moss, oil and eggs is said to be effective, but their phamacological functions are not clarified. In view of the above results, we can realize that the drugs that have been employed in herb remedies are quite diverse. However, in regard to majority of herb remedies that have been employed by symptoms, the pharmacological functions of their drugs have not been clarified, and they are merely known as effective. Furthermore, they have not been recorded in the literature as yet ; and we confirm that there have been many herb remedies that were executed without the proper knowlege of their effects. It is now our view that the results of this survey may be utilized for consulting data in regard to the use of herb remedies.

  • Objective : In this study, we assessed the anti-bacterial effects and epidermal permeability barrier function of red onion juice comparing to yellow onion juice and $Houttuynia$ $cordata$ extract $in$ $vitro$. Methods : 3types of red and yellow onion juice were prepared as antibacterial agent candidates with Houttuynia cordata hot water extract using 4 different bacterial strains ($Escherichia$ $coil$, $Salmonella$ $enterica$ $subsp.$ $enterica$, $Staphylococcus$ $epidermidis$, $Staphylococcus$ $aureus$ $subsp$) by colony counting method. The expression of filaggrin, a marker of keratinocyte differentiation, and serine palmitoyl transferase (SPT), a marker of the formation of the stratum corneum lipid barrier, in human HaCat keratinocytes were analyzed using HaCaT cell line. The expression of COX-2 and AP-1 which is a factor of COX-2 transcription were also analyzed by western blotting method. Results : There was detectable anti-bacterial effects on $Staphylococcus$ $epidermidis$, $Staphylococcus$ $aureus$ $subsp$ among 1%, 5%, 10% extracts of yellow and red onion.(81%-100%) The bacteriocidal effects were not shown on $Escherichia$ $coil$, $Salmonella$ $enterica$ $subsp.$ $enterica$ among $Houttuynia$ $cordata$, yellow onion and red onion extracts. The in vitro results showed the concentration-dependent effects on the expression of both filaggrin and SPT in HaCat cells among 0.01%, 0.05%, 0.1%, 0.5% extracts in Houttuynia cordata and red onion, reflecting the notion that $Houttuynia$ $cordata$ and red onion can induce epidermal keratinocyte differentiation and improve the recovery of skin barrier functions. The concentration-dependent effects also have been shown on the expression of both COX-2 and AP-1 among 0.01%, 0.05%, 0.1%, 0.5% extracts in $Houttuynia$ $cordata$ and red onion, while slight effect in yellow onion. Conclusion : Red onion juice could be a potential candidate enhanser for the skin care and cosmetology.

  • The purpose of this study is to identify the causation and variation among the various types of onion prices in the major production sites to predict these prices. The Granger causal relationship was tested on the basis of VECM by setting the onion price of the early, middle, and late species as individual variables. The analysis shows that the amount of onions produced in the prior term affects the price of onions for the later period, while garlic in the substitution relationship with onions also affects the prices of onions for the early and middle-variety. On the other hand, the price of the late-variety is affected by the price of the early-variety, and the price of the middle-variety is also affected by the price of the early-variety. If the price of onions on Jeju changes due to other factors, the prices of onions in Jeollanam-do and Gyeongsangnam-do provinces will be affected. Accordingly, when the production of late-variety increases or decreases in production under any factor and to promote stability of the prices of middle and late-variety through preemptive supply and demand measures when the prices of ultra-breed onions rise or fall due to any factor (Ed- I cannot understand this last sentence and cannot guess at the correct meaning. Please try to rewrite very simply).

  • Lipid transfer proteins (LTPs) are widely distributed in the plant kingdom, but their functions remain elusive. The proteins AlLTP2-4 were isolated from three related Allium plants: garlic (A. sativum L.), Welsh onion (A. fistulosum L.), and Nanking shallot (A. ascalonicum L.). These novel proteins comprise a new class of LTPs associated with the Ace-AMP1 from onion (A. cepa L.). The AlLTP genes encode proteins harboring 132 common amino acids and also share a high level of sequence identity. Protein characteristics and phylogenetic analysis suggest that LTPs could be classified into five distinct groups. The AlLTPs were clustered into the most distantly related plant LTP subfamily and appeared to be restricted to the Allium species. In particular, the number of amino acids existing between the fourth and fifth Cys residue was suggested as a conserved motif facilitating the categorization of all the LTP-related proteins in the family. Unlike other LTPs, AlLTPs harboring both the putative C-terminal propeptide and N-terminal signal peptide were predicted to be localized to cytoplasmic vacuoles. When a chimeric GFP protein fused with both N-terminal and C-terminal AlLTP2 signal peptides was expressed in rice cells, the fluorescence signal was detected in the endomembrane compartments, thereby confirming that AlLTPs are an unprecedented intracellular type of LTP. Collectively, our present data demonstrate that AlLTPs are a novel type of LTP associated with the Allium species.

  • This study was conducted to assess the effect of highly concentrated onion intake on rodents. The experimental animals were divided two groups as follows; water administered group (CON) and Allium cepa administered group (ACE). The ACE group showed a slightly increases in the number of erythrocytes (RBC), hemoglobin (HGB), hematocrit (Hct) levels compared to the control group (p<0.05). Hemoglobin, monocyte, lymphocyte and neutrophil had no significant change (p>0.05) in ACE group and control group. The analysis of glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) levels showed a significant decrease in ACE group compared to the control group (p<0.05). The blood glucose, total protein, HDL-cholesterol were slightly high in ACE group, while triglyceride, total cholesterol levels were lower in ACE group compared to the control group (p<0.05). The levels of cytokines (interluekin-1α (IL-1α), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-10 (IL-10), interferon-γ (INF-γ), interleukin-18 (IL-18), interleukin-2 (IL-2), granulocyte-macrophage colony-stimulating factor (GM-CSF)) involved in immunity and inflammation in liver tissue and blood have all been confirmed to be within normal range. These findings could be used as basic data to show that highly concentrated dietary onion extract is not toxic to hematological indicators and immune functions.
