The present paper was carried out to clear up the polyploidal constitution and the banding pattern of three species in tetraploidal Allium(X=8) through the studies of meiosis, karyotype and G-bands. From the meiotic data and G-banding patterns obtained under this study, it is confirmed that A. tuberosum and A. chinense are autotetraploids, and A. senescens is allotetraploid. Some aneuploids out of the employed species were found; A. senescens is 2n=34, and A. chinense is 2n=33. The chromosome types of these species are meta-and submetacentrics except the sat-chromosomes and the f-chromosomes. G-bands of these species are generally located in the end of each arm. A. senescens is similar in the quantity of heterochromatin with A. chinense, but A. tuberosum has a little than the other species. The quantity of heterochromatin is higher in small groups of chromosome than large ones, and higher in short arms than long arms.

To develop Allium tuberosum L. as a cancer preventive food material, thiosulfinates and biological active components were isolated from Allium tuberosum L. and the apoptotic effects of thiosulfinates in human cancer cells were examined. Thiosulfinates decreased viable cell numbers in dose- and time-dependent manners. Thiosulfinates at the 20 $\mu g$/mL concentration inhibited more than 60% cell proliferation in HepG2 and A549 human cancer cells, respectively. Also the morphology of cells treated with thiosulfinates of 30 $\mu g$/mL concentration was distorted with shrunken cell mass while the cell number was lower than that of control cells. The $IC_{50}$ values in the HepG2 cells were higher than those of the A549 cells. Thiosulfinates at the 30 $\mu g$/mL concentration showed the formation of apoptotic bodies and a nuclear condensation, and an increase in the cell populations of the sub-G1 phase in the HepG2 cells. These results indicate that thiosulfinates from Allium tuberosum L. inhibited cell proliferation in HepG2 via apoptosis.

The garlic chive (Allium tuberosum Rotter) is a prominent herb species in Asia and other nations of the world. Garlic chives is a favorite vegetable and used to garnish noodles in Korea. The effects of various doses of N, P, and K fertilizers and drought stress on the chlorophyll content in the leaves of garlic chives were investigated. The evaluations showed that chlorophyll a content was 0.386 at 10 mg/l N fertilizer and 0.584 at 50 mg/l N fertilizer. The treatment group showed a significant difference with regard to the contents of chlorophylls a and b and total chlorophyll at the 5% level (p<0.05). Pearson's correlation coefficient (Pearson's r) for chlorophylls a and b and total chlorophyll were 0.940, 0.966, and 0.971, respectively. The highest content of chlorophylls a and b and total chlorophyll in the leaves was recorded at 40 mg/l P fertilizer, while the values corresponding to 50 mg/l P fertilizer were lower than those for 40 mg/l P fertilizer. The content of total chlorophyll evaluated at 10 mg/l K fertilizer was 0.312 and that at 50 mg/l was 0.589. The simple linear regression showed the relationship between chlorophyll efficiency aand moisture. The slope factors of the dark-level fluorescence yield (Fo), the maximum fluorescence yield (Fm), the quenched state (Fv), and the maximal PSII quantum yield (Fv/Fm) for chlorophyll-efficient indicators were -0.931, 0.972, 972, and 0.950, respectively. NPK fertilizers and drought stress affected the chlorophyll content and efficiency of A. tuberosum.

In this study, we characterized sporadically occurring sclerotium rot caused by Sclerotium rolfsii in Chinese chive (Allium tuberosum Roth.) in farm fields in Sacheon, Korea. The initial symptom of the disease was water-soaked, which progressed to rotting, wilting, blighting, and eventually death. Further, mycelial mats spread over the lesions near the soil line, and sclerotia formed on the scaly stem and leaves. The sclerotia were globoid, 1~3 mm, and white to brown. The optimum temperature for growth and sclerotia formation on potato dextrose agar (PDA) was $30^{\circ}C$. The diameter of the hypae ranged from 4 to 8 ${\mu}m$. Clamp connection was observed on PDA medium after 5 days of incubation. Based on the mycological characteristics, internal transcribed spacer sequence analysis, and pathogenicity test, the causal agent was identified as Sclerotium rolfsii Saccardo. This is the first report of sclerotium rot in Chinese chive caused by S. rolfsii in Korea.

This study was conducted to observe the hematological effect of the small dogs when administrated excessive amount of the Korean native chinese chive(Allium tuberosum Rottler) extracts for a short period. In this experiment, clinically healthy dogs(n = 10, average weight = 4.17 kg) were used. They were inserted stomach tube and administrated the extracts(5ml/kg) for 7 days. The followings are the result of this experiment. The red blood cell counts, hemoglobin concentration and mean corpuscular hemoglobin concentration were significantly decreased. (P<0.05) The packed cell volume was slightly decreased. The mean corpuscular volume and methemoglobin concentration were significantly increased.(P<0.05) The white blood cell counts and reduced glutathione were slightly increased. Consequently, We determined that administrated excessive amount of the Korean native chinese chive extracts induced hemolytic anemia.

We have studied the effect of 31 extracts and 10 components from some edible and medicinal plants on the formation of lipid peroxide in the liver homogenate of rat in vitro. The 70% acetone extracts of Allium tuberosum, Beta vulgaris var. cicla and Brassica juncea var. integrifolia, and methanol extract of Capsicum annuum decreased the formation of lipid peroxide by 33%, 58%, 62% and 56% at the concentration of 1mg/ml, respectively. And these four extracts inhibited the lipid peroxidation at the concentration of $10^{-1}$mg/ml by 17%, 46%, 49% and 45% respectively. Among the component tested, quercetin, quercitrin and isorhamnetin reduced the formation of lipid peroxide by 45%, 15% and 28% respectively at the concentration of $10^{-2}$mg/ml.

Objectives : The present study was designed to evaluate the protective effect of Allium tuberosum (AT) extract on atherosclerosis in LDL receptor knockout (LDLr KO) mouse fed western diet.Methods : The AT was extracted 70% ethanol. The experimental groups were divided with four groups of LDLr KO mice, one group fed a normal diet and the others fed a Western diets for 8weeks. Two Western diet groups were orally administered AT extract at dosage of 100 and 300 mg/kg body weight. The body weight and food intake were measured every day. We measured levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and Glucose in serum. Also, effect of AT extract performed using H&E staining.Results : The AT treatment groups showed decrease in body weight and food efficiency in comparison with control group. Blood biochemistry parameters such as TG, TC, LDL, and glucose levels were increased in control group, while AT treatment groups were reduced. Also, the increased levels of ALT and AST were improved by AT extract. We confirmed that the weights of liver, kidney, subcutaneous fat, epididymal fat, kidney leaf fat, and intraabdominal fat were change in LDLr KO mice treated AT extract. In addition, histopathological changes in liver and aorta were similar to normal group.Conclusions : Based on these results, the AT extract is considered to make prevention of atherosclerosis through reduction and functional improvement of the liver and vascular endothelial cells in the body fat accumulation and lipid content in LDLr ko mouse model.

The effect of retarding the fermentation of Kimchi by the extract of leek(Allium tuberosum) were tested by measuring the changes in pH, acidity and total cell number as well as number of microorganisms involved in Kimchi fermentation such as Lactobacillus, Leuconostoc, Pediococcus, Streptococcus and yeasts. The changes of pH and acidity of Kimchi stored at $25^{\circ}C$ indicated that the shelf-life of Kimchi with leek extract was retarded by 1.5 days compared with Kimchi without leek extract. Growth of Lactobacillus, Leuconostoc, Pediococcus and yeasts in Kimchi were remarkably inhibited by adding the leek extract at the initial and the 1st day of fermentation. This result suggested the methanol extract of leek can be sucessfully used for the extension of shelf-life of Kimchi.
