In recent years, Allium victorialis has been extensively used as a pharmacological agent for various diseases in the form of anti-arteriosclerotic, anti-diabetic and anti-cancer. Allium victorialis is severely affected by various fungal diseases since it naturally grow in the shady and humid environments in Korea. In this case, different types of fungicides are applied to control the fungal diseases in Allium victorialis. The present study was aimed to determine the residual characteristics of two fungicides namely tebuconazole and fludioxonil on Allium victorialis. For this study, the fungicides were drenched soil on Allium victorialis in the cultivation area Pyeongchang by the standard (two thousand fold) and double (thousand fold) dilutions. At the end of $15^{th}$, $30^{th}$ and $40^{th}$ days samples were collected for residue analysis. Residues of tebuconazole and fludioxonil were analyzed using GC/NPD (Gas Chromatography/Nitrogen Phosphorus Detector) and their recovery were found to be 108.8~119.5% and 91.3~104.8%, respectively. The method of limits of quantification for both fungicides was $0.01mg\;kg^{-1}$. Further, the results of this study shows that the residue levels of both fungicides on Allium victorialis were <$0.01{\sim}0.12mg\;kg^{-1}$ and $0.01{\sim}0.09mg\;kg^{-1}$ and their % ADI (% Acceptable Daily Intake) were 17.44% and 25.75%, respectively. Based on the results obtained in this study, we suggest that the residue levels of both of the fungicides on Allium victorialis are safe and these fungicides can also be used to control fungal diseases in Allium victorialis.

The purpose of this study was to investigate the effect of taekwondo and allium tuberosum intake on body composition, blood lipids and C-reactive protein in male high school students. Twenty-four male students of B city volunteered to be test subjects. Experimental groups were taekwondo with allium turberosum group (A, n=6), taekwondo group (B, n=6), allium tuberosum group (C, n=6), control group (D, n=6). The total experimental period was 10 weeks. Groups A and B practiced taekwondo 4 times a week for 10 weeks with an intensity of 60~80% HRR. Each practice was 50 minutes. Groups A and C were instructed to take an allium tuberosum pill every day before their taekwondo exercise during the 10 weeks. The results of this study are as follows: Within groups A, B and C, there was a significant decreas in % fat. Groups A and B showed a significant increase in HDL-C concentration, as well as a more significant increase in HDL-C concentration than groups C and D. Group A showed a more significant decreased in LDL-C concentration than group D. In conclusion, taekwondo and allium tuberosum intake seem to have a positive effect on % fat, HDL-C and LDL-C. Further research regarding the effect of allium tuberosum diets is required.

This research was conducted to investigate morphological and genetic variation of Allium victorialis val. platyphyllum which growed wild in Mt. Hambaek, Mt. Odae, and Ullungdo. The tree layer of Allium victorialis var. platyphyllum community in Mt. Hambaek and Mt. Odae was dominated by Quercus mongolica. The tree layer of Ullungdo generally consist of Fagus crenata var. multinervis, Acer triflorum, Sorbus commixta, and Tilia insularis. In the herb layer, Rumohra standishii, Trillium tschonoskii, and Lilium hansonii are common at Allium victorialis var. platyphyllum community in Ullungdo. The vegetation in Ullungdo was widely different from those in Mt. Hambaek and Mt. Odae by species composition. The result of Principal Component Analysis(PCA) and Canonical Discriminent Analysis of by the 8 characters showed that Allium victorialis var. platyphyllum could be classified into 2 groups: (one ; Mt. Hambaek and Mt. Odae, the other ; Ullungdo). In PCA, the major factors in the first principal component group was angle of leaf apex. Variation of band by isozyme GOT(glautamate oxaloaccetate transaminase) is similar between Mt. Hambaek and Mt. Odae. However, Ullungdo differed from Mt. Hambaek and Mt. Odae in variation of bands.

The aim of this study was to investigate the physicochemical characteristics of native Korean Allium wakegi Araki samples, which were grown from seven local seed bulbs(Yesan, Muan, Anmyon-do, Deokjeok-do, Jeju-do, Yecheon, and China) to produce high quality native Korean Allium wakegi Araki. For the proximate composition of samples, moisture contents were in the range of 90.69~92.43%. The crude protein content of the Jeju-do sample was highest compared to the other samples. However, there were no significant differences in total sugar contents between samples. The seed bulb origin did not affect the hardness of the stem part, but was high for the leaves of the Yesan sample compared to the other samples. The results for anti-oxidative activity were as follows: Yesan(2.30 mg/mL) > China(2.51 mg/mL) > Muan (2.56 mg/mL) > Yecheon(2.74 mg/mL) > Jeju-do(2.85 mg/mL) > Anmyon-do(2.87 mg/mL) > Deokjeok-do(3.18 mg/mL). In terms of mineral and amino acid contents, the Yesan sample showed the highest levels, respectively, compared with the other samples. Food values such as contents of total phenolics and pyruvic acid were highest in the Jeju-do sample. These results show that the physicochemical characteristics of Allium wakegi Araki were significantly different according to different seed bulb origins.

The purpose of this study was to investigate the effects of aerobic exercise and Allium tuberosum intake on blood lipids, MDA and antioxidant enzyme in rats. Twenty four male Sprague-Dawley rats, 4 weeks old, were used. Experimental groups were aerobic exercise with Allium tuberosum intake group (A, n=6), aerobic exercise group (B, n=6), Allium tuberosum intake group (C, n=6), and the control group (D, n=6). Aerobic exercise was administered through a treadmill running program (14~15 m/min, $0^{\circ}$ grade, 25~30 min/day, 5 day/wk) and these rats were given 5% Allium tuberosum for 2 wk. The results of this study are as follows: TC and TG didn't show change; groups A, B, C showed a significant increase in HDL-C compared to the D group; groups A, B, and C showed a significant decrease in LDL-C compared to the D group; groups B and C showed a significant decrease in MDA level compared to the D group; groups B and C showed a significant increase in SOD activity compared to the D group; and the A group showed a significant increase in CAT activity compared to the D group. In conclusion, low intensity aerobic exercise and intake of the natural antioxidant Allium tuberosum seem to have the health promoting effect of retarding oxidative stress by decreasing lipid peroxidation.

Diabetes mellitus is associated with insulin resistance, which leads to down-regulation of insulin signaling and the decreased glucose uptake. Adipocytes are sensitive to insulin, and closely implicated in insulin resistance and diabetes. Insulin stimulates differentiation of preadipocytes to adipocytes, and increases glucose transport. Allium species have been used as traditional medicine and health-promoting foods. Allium hookeri (A. hookeri) is reported to improve the pancreatic ${\beta}-cell$ damage and exhibit pancreatic anti-inflammatory activity in streptozotocin-induced diabetic rats. We investigated whether A. hookeri extract (AHE) may stimulate glucose uptake in adipocytes through increasing insulin sensitivity. AHE enhanced fat accumulation, a differentiation biomarker, under the partial induction of differentiation by insulin. $PPAR{\gamma}$, a transcription factor highly expressed in adipocytes, promotes adipocyte differentiation and insulin sensitivity. AHE increased the differentiation of preadipocytes through up-regulation of $PPAR{\gamma}$. The activation of $PPAR{\gamma}$ increases the GLUT4 expression during adipocyte differentiation. GLUT4 is responsible for glucose uptake into the adipocytes. AHE increased the expression of GLUT4 in adipocytes, and subsequently enhanced the insulin-stimulated glucose uptake. These results suggest that AHE promotes adipocyte differentiation through activation of $PPAR{\gamma}$, and leads to enhance glucose uptake in adipocytes along with GLUT4 up-regulation. Thus, AHE may be effective for the insulin-sensitizing and anti-diabetic activities.

The investigation was aimed to reduce the period of bed log through the protection of harmful fungi and to know the effects of physiological activating substances on the yield increase of Lentinus edodes. Mycelial growth was evaluated both the bed logs and physiological activating substances, respectively. I percent extract of Allium cepa and malt as a physiological activating substance was highly effective in mycelial growth of Lentinus edodes. Better effects among the bed logs by the application fo physiological activating substances observed in both Quercus serrata and Carpinus laxiflora. This results suggested that supplement of physiological activating substances to the bed log would be beneficial for the production of Lentinus edodes.

Among 100 species in 54 families of plants tested, leaf extracts from Allium cepa, Allium sativum, Malussieboldii, Reynoutria japonia and Rheum coreanum were inhibitory on mycelium growth of phytophthora spp.. Especially, Allium sativum and Malus sieboldii were strongly inhibitory. Allium sativum, Malussieboldii and Rhem coreanum were strongly inhibitory on zoosporangium germination of P. capsici. Malus sieboldii only were strongly inhibitory on zoosporangium germination of P. nicotiana and P. infestans.And Malus sieboldii were strongly effected on disease control of these pathogens. These results indicate the possibility of finding antagonistic plants in the nature for the control of certain pathogens in soil.
