  • The adult of the Cotton caterpillar, Palpita indica (Saunder) laid eggs more on mature leaves than on aged and developing leaves. They laid more on leaves than on petiole and stem, and more on the adaxial than on the abaxial surface side of the leaves. Larvae of the Cotton caterpillar showed their preference in the order of the cucumber (Cucumis sativus), gourd (Lagernaria siceraria), watermelon (Citrullus lanatus) > oriental melon (Cucumis melon L. var makuwa), wax gourd (Benincasa hispida), melon (Cucumis melo), star cucumber (Sicyos angulatus) > sponge cucumber (Lufa cylindrica), cotton (Gossypium indicum). There were no distinct differences among varieties and lines that were collected and hybridized at the Gochang Watermelon Experiment Station in Korea. There was a positive relationship between the leaf area and the degree of damage by the Cotton caterpillar. The feeding amounts of the Cotton caterpillar excrement were gradually increased to 16-18 days after hatching, after that the amounts of excrement were rapidly decreased.

  • This study was designed to examine the effects of fractions of ethanol extract of Benincasa hispida (wax gourd) on plasma glucose and lipid levels in streptozotocin (STZ) induced diabolic rats. sprague-Dawley rats were induced diabetes mellitus by STZ injection (45 mg/kg) into the tail vein and were divided into 5 groups: normal, STZ-control, three experimental diabetic groups. fractions of ethanol extract of Benincasa hispida were administered orally into the diabetic rats for 14 days. The food intake and body weight were monitored and plasma levels of glucose, cholesterol, HDL-cholesterol, triglyceride (TG) , free fatty acid (FFA) , and aminotransferase activity were analyzed. A significant lowering effects of plasma glucose levels were observed in the chloroform fraction and $H_2O$ fraction group compared to STZ-control group at 14 days. Administrations of each of the three fractions decreased plasma TG and FFA levels in diabetic rats. Activity of alanine aminotransferase (ALT) in $CHCl_3$ fraction and $H_2O$ fraction groups and aspartate aminotransferase (AST) in $H_2O$ fraction group significantly lower than STZ-control group. The results show that $CHCl_3$ fraction of Benincasa hispida could be effective to control the STZ-induced diabetic rats. (Korean J Nutrition 38(10): 801$\sim$806,2005)

  • A pathogen that causes a new disease on green pumpkin in the nursery and the field was characterized and identified. Symptoms of the disease on green pumpkin were water soaking lesions and spots with strong yellow halo on leaf, brown lesion on flower, and yellow spot on fruit. The bacterial isolates from the leaf spot were pathogenic on the 8 curcubitaceae crop plants, green pumpkin, figleaf gourd, wax gourd, young pumpkin, zucchini, cucumber, melon, and oriental melon, whereas they did not cause the disease on sweet pumpkin and watermelon. They were Gram-negative, rod shape with polar flagella, fluorescent on King's B agar and LOPAT group 1a by LOPAT test. Their Biolog substrate utilization patterns were similar to Pseudomonas syringae pv. syringae's in Biolog database. Phylogenetic trees with 16S rRNA gene sequences and multilocus sequence typing (MLST) with nucleotide sequences of 4 housekeeping genes, gapA, gltA, gyrB, rpoD and those of P. syringae complex strains in the Plant Associated and Environmental Microbes Database (PAMDB) showed that the green pumpkin isolates formed in the same clade with P. syringae pv. syringae strains. The clade in MLST tree was in the genomospecies 1 group. The phenotypic and genotypic characteristics suggested that the isolates from green pumpkin lesion were P. syringae pv. syringae.

  • To produce bio-active Kochujang, 1.2% of pomegranate powder, 1.0% of hawthorn berry extract powder, 0.01% of ginko biloba extract, 1.2% of red yeast rice powder, 1.2% of silk powder, 0.2% of garlic oil, 0.2% of chitosan, 1.2% of wax gourd extract powder, and 1.0% of pine mushroom were added individually with raw materials that are needed for Kochujang process. These Kochujangs were fermented for 45 days at $30^{\circ}C$, and examined for changes in their physicochemical properties. There were no significant differences in pH, acidity, formol-N content, color and total cell count by plate count agar between Kochujangs fortified individually with functional ingredients and the control Kochujang. When 0.2% of garlic oil was added, antioxidant activity of its Kochujang product increased twice as much as that of the control Kochujang. Improved ACE inhibiting activities were observed in 1.2% of red yeast rice powder. When 1.2% of silk powder or 0.01% of ginko biloba extract were added, antithrombotic abilities were remarkably enhanced up to two times of the control Kochujang.

  • The 2%, 3% of deer young antler, deer antler, oystershell, crabshell, eggshell were add into the 5%, 10%, 15% solution of glacial acetic acid and vinegar and after incubating it for 4 days at $30^{\circ}C$ respectively, solubility was analyzed. The result shows the difference was minute between glacial acetic acid and vinegar. In the 2% content of deer young antler, solubility was 42~47%, in the 3% content of it, solubility was 41~47%, with the acid concentration becoming higher, solubility increased slightly. In the 2% content of deer antler, solubility was 59~63%, in the 15% content of acid, solubility rather decreased. In the 2% content of oystershell, solubility was 85~96%, in the 3% content, solubility was 95~98%, in the 15% of acid density, it decreased. In the 2% content of crabshell, solubility was 79~88%, in the 3% content, solubility was 81~95%, and in case that acid density was high, solubility increased rather slightly. In the 2% content of eggshell, solubility was 84~96%, in the 3% content, solubility was 84~93%. When young deer antler and deer antler were heated for two hours at $100^{\circ}C$, solubility increased 19~24%, and in the case of crabshell, 10~11% increased. The above result and condition, and the result of pH and acidity don't have much influence on solubility. Thus, the 5% of acidity was enough to melt the 3% of sample. Highest were glacial acetic acid and vinegar in solubility to the various organic acid, and wax gourd vinegar melted the 85% of oystershell, the 78% of crabshell, the 28% of the deer young antler, and in the precipitation was made. Citric acid melted the 57% of deer antler, but it was precipitated with all other samples. Ascorbic acid melted the 92% of eggshell, and did the 37~54% of other samples.

  • The effects of fractions of ethanol extract of Benincasa hispida (wax gourd) on lipid levels and lipid peroxidation in streptozotocin (STZ) induced diabetic rats were examined. Sprague-Dawley rats were induced diabetes mellitus by STZ injection (45 mg/kg) into the tail vein and were divided into 5 groups: normal, STZ-control, three experimental diabetic groups [chloroform $(CHCl_3)$ fraction group, butanol (BuOH) fraction group, and water fraction group]. Fractions of ethanol extract of Benincasa hispida were administered orally into the diabetic rats for 14 days. The liver glycogen levels of $CHCl_3$ fraction group and the muscle glycogen levels of BuOH and water fraction groups were significantly higher than that of STZ-control group. Pancreas protein levels of BuOH and water fraction groups were significantly higher than that of STZ-control group. The liver cholesterol level of BuOH and water fraction groups were significantly lower when compared with the STZ-control group. The level of liver triglyceride in BuOH and water fraction groups were significantly higher than that of STZ-control group. Malondialdehyde (MDA) levels in liver of normal and diabetic groups were not significantly different. In the pancreas, the MDA levels of BuOH and water fraction group were significantly lower than that of STZ-control group. The results suggested that the supplementation of the BuOH and water fractions of Benincasa hispida extract could be beneficial for the diabetic complications and damages from the lipid peroxidation.
