Pesticide contaminants content was determined about both general vegetables marketed at Garak-dong market and organic vegetables cultivated at Hongchun, Kangwon-do. The vegetables were kale, Angelica Keiskei Koidz, celery, lettuce and Allium fistulosum. Pesticide contaminants content of 5 kinds general vegetables were 93.5, 57.7, 112.4, 76.5, 65.2 ppm, respectively. This residual levels were showed 75.35, 70.68, 78.49, 70.49％ about standard level, respectively. Angelica Keiskei Koidz was not able to calculate the residual level because the standard level was not established in Korea. In contrast, the residual levels of organic vegetables were determined 36.4, 21.0, 42.9, 29.1, 25.1ppm, respectively. This level was about 30％ of standard level, 38.93, 36.40, 38.17, 38.04, 38.50％ of general vegetables. At the result, pesticide contaminants content of organic vegetables was less than 40％ of general vegetables.

This study was carried out to find optimum concentration of germanium compounds and pH of medium on the induction and growth of callus from A. keiskei and P. ginseng and to intend to increase Ge. absorption by calli while those calli were subculturing on MS medium. Callus from a. keiskei was rarely induced under light condition. Under dark condition, callus in­duction from A. keiskei was good up to 5ppm, retarded at 50ppm of $GeO_2$, or C. E. Ge. O., and rarely done at 100 ppm of $GeO_2$ but was somewhat well at 100 ppm of C. E. Ge. O. The induction and growth of callus was good in order of pH 5. 7 > pH 5. 4 > pH 6. 0 Under light condition, the growth of callus induced from P. ginseng was poor at $1{\sim}10\;ppm$ of $GeO_2$, or C. E. Ge. O., but shooting from callus occurred frequently. Under dark condtion, the growth of callus from A. keiskei was good up to 5 ppm of $GeO_2$, or C. E. Ge. O. and was rarely done at 50 ppm of $GeO_2$, but was somewhat well even at 100 ppm of C. E. Ge. O. Shooting from callus occurred frequently in a. keiskei, especially at pH 5.7. The growth of callus from P. ginseng was poor at 10 ppm of $GeO_2$, or 50 ppm of C. E. Ge. O. Under dark condition, the amount of Ge absorption by callus induced from A. keiskei was much high­er than that from P. ginseng. The amount of Ge. absorption by callus treated with $GeO_2$, was higher than that treated with C. E. Ge. O.

Muscle atrophy, which is defined as a decrease in muscle mass and strength, is caused by an imbalance between the anabolism and catabolism of muscle proteins. Thus, modulating the homeostasis between muscle protein synthesis and degradation represents an efficient treatment approach for this condition. In the present study, the protective effects against muscle atrophy of ethanol extracts of Morus alba L. (MA) and Angelica keiskei Koidz. (AK) leaves and their mixtures (MIX) were evaluated in vitro and in vivo. Our results showed that MIX increased 5-aminoimidazole-4-carboxamide ribonucleotide-induced C2C12 myotube thinning, and enhanced soleus and gastrocnemius muscle thickness compared to each extract alone in dexamethasone-induced muscle atrophy Sprague Dawley rats. In addition, although MA and AK substantially improved grip strength and histological changes for dexamethasone-induced muscle atrophy in vivo, the efficacy was superior in the MIX-treated group. Moreover, MIX further increased the expression levels of myogenic factors (MyoD and myogenin) and decreased the expression levels of E3 ubiquitin ligases (atrogin-1 and muscle-specific RING finger protein-1) in vitro and in vivo compared to the MA- and AK-alone treatment groups. Furthermore, MIX increased the levels of phosphorylated phosphoinositide 3-kinase (PI3K), protein kinase B (Akt), and mammalian target of rapamycin (mTOR) that were reduced by dexamethasone, and downregulated the expression of forkhead box O3 (FoxO3a) induced by dexamethasone. These results suggest that MIX has a protective effect against muscle atrophy by enhancing muscle protein anabolism through the activation of the PI3K/Akt/mTOR signaling pathway and attenuating catabolism through the inhibition of FoxO3a.

This study investigated the effects of dietary supplementation of fermented apple pomace (FAP), fermented pear pomace (FPP), fermented orange pomace (FOP), and fermented Angelica keiskei Koidz pomace (FAKP) on performance, shelf life, fatty acid composition and cholesterol in broiler chickens. A total of 600, 1-day-old male broiler chicks (Cobb strain) were randomly divided into six groups with four replicates of 30 birds each. There were five treatment groups: control (C), FAP (1.0%, T1), FPP (1.0%, T2), FOP (1.0%, T3), and FAKP (1.0%, T4). The body weight of the broiler chickens fed FAP diet was higher (1,758 g) than the other treatments. There was no difference in the thiobarbituric acid reactive substances (TBARS) in chicken meat between all groups at days 1, 3, and 5 of storage, while the FAP-supplemented group displayed lower TBARS values at day 7. There was no significant difference in fatty acid composition between the groups but the cholesterol content of chicken meat was lower than the control groups. These results suggest the possibility that FAP could be used as a functional feed to improvement the quality performance of broiler chickens.

This study was carried out to increase the rate of plant regeneration from embryogenic callus of A. keiskei on MS medium supplemented with ethylene inhibitors. When leaflet, petiolule, and petiole of A. keiskei were cultured on MS medium supplemented with 2, 4-D, callus was well induced from leaflet segments at 2.0 ppm 2, 4-D. Shoot elongation of plantlets and shooting from embryogenic callus of A. keiskei were best on 2, 4-D-free medium supplemented with 2 ppm $AgNO_3$ or 10 ppm $CoCl_2{\cdot}6H_2O$, but it was suppressed on the medium containing 1 ppm 2, 4-D with $AgNO_3$ or $CoCl_2{\cdot}6H_2O$. Root elongation of plantlets from embryogenic callus was best on 2, 4-D-free medium supplemented with 1 ppm $AgNO_3$ or 5 ppm $CoCl_2{\cdot}6H_2O$, but rooting from embryogenic callus was none on the medium containing 1 ppm 2, 4-D with $AgNO_3$ or $CoCl_2{\cdot}6H_2O$. Fresh weight of plantlets from embryogenic callus was heaviest on 2, 4-D-free medium supplemented with 2 ppm of $AgNO_3$ or $CoCl_2{\cdot}6H_2O$, while it was heaviest on the medium containing 1 ppm 2, 4-D with 1 ppm $AgNO_3$ or 2 ppm $CoCl_2{\cdot}6H_2O$.

Proximate components, minerals, vitamins and chlorophyll contents were determined in vegetables purchased at Garak-dong market and organic vegetables cultivated at Hongchun, Kangwon-do. The vegetables were Kale, Angelica Keiskei Koidz, Celery, Lettuce and Allium fistulosum. In proximate component contents, analyzed crude protein and fat contents of organic vegetables were higher than those of general vegetables. Organic vegetables had strong green color. Minerals such as sodium, potassium, calcium, phosphorus, iron as well as vitamins were determined. Contents of minerals and vitamins in organic vegetables were higher than those of general vegetables. Total mineral content of organic and general kales were 811.8 mg/l00g, and 688.1 mg/l00g, respectively. Total mineral content of organic Angelica Keiskei Kowz, Celery, Lettuce and Allium fistulosum were 447.9, 486.5, 368.6, and 320.9 mg/100g, respectively.

There has been increasing research interests that green vegetables play beneficial roles in human health. This study was performed to investigate the effects of freeze-dried green vegetable extract of Angelica keiskei Koidz (A) and Brassica oleracea acephala (B) on lipid profiles and antioxidant status in rats. Seven-weeks old male Sprague Dawley rats were divided into 6 groups and fed diets containing 5% A & B and 0.5% cholesterol (cho) for 8 weeks [Control Diet (C) & C + chol (CC), A & A + chol (AC), B & B + chol (BC)]. Lipid profiles and antioxidant status were determined by enzyme assay methods. The serum levels of [LDL + VLDLJ-cholesterol of the rats fed vegetable extract diets A and B were significantly lower than that of group C and the ratios of HDL/[LDL + VLDL] were significantly higher in groups A and B. Addition of cholesterol in the diet, however, abolished this effect. The Brassica oleracea acephala juice lowered serum TG level even when cholesterol was added to the diet. Serum total antioxidant status(TAS) were significantly higher in groups A and B as compared to the control group and the ratios of [GSH-Px +Catalase]/total-SOD in the liver were also significantly higher in groups A and B indicating that H202 produced be efficiently removed. In conclusion, freeze-dried green vegetable extract diets (A and B) improved serum lipid profiles by increasing the HDL/[LDL + VLDL〕 ratio and exerted favorable influences on antioxidant systems by improving total antioxidant status (TAS) in serum and by significantly increasing the ratio of [GSH-Px + Catalase]/total-SOD in the liver.
