BACKGROUND/OBJECTIVES: This study measured the effects of a taste education program developed in Korea on food neophobia and willingness to try novel foods in school children. SUBJECTS/METHODS: One-hundred and twenty school children (aged 7-9 years) residing in Seoul participated in 12 sessions of a taste education program for 3 months. The Korean taste education program was adapted from "Les classes du gout" by J. Puisais and modified to suit a Korean education environment. The study subjected school children to pre- and post-programs on food neophobia and willingness to try novel foods (WTNF), in addition to children's food neophobia in their parents. A total of 101 survey data were analyzed using SPSS 18.0. RESULTS: Regarding the effects of taste education, scores of food neophobia significantly decreased (P < 0.01) in the posttest, mean (m) score ($4.10{\pm}1.19$) decreased compared to the pretest ($4.39{\pm}1.00$), and WTNF significantly increased (P < 0.001) in the pretest (m) score ($0.48{\pm}0.33$) compared to the pretest ($0.32{\pm}0.34$). This result indicates verification of the study hypothesis. CONCLUSIONS: Food neophobia scale (FNS), an index that measures personal food preference [1,2], showed a very weak correlation with behavioral willingness to taste novel foods (WTNF). Therefore, it is expected that the two scales measure different things. However, considering that the traits of food neophobia are not easily changed, the taste education program was administered in a remarkably effective manner.

Korean aconitum (Aconitum koreanum R. Raymond) as one of the botanical crude drugs which pertain to helleboraceae has been extensively applied in Chinese medicine during the past decades. It has been particularly used in immortal tonic among the folk remedies in China, however, its general uses comprehend diuresis, cardiotonic, analgesia, neuralgia, gout and, furthermore, even neoplastic effect. The components of aconitum have been acknowledged as aconitine, mesaconitine, hypaconitine, aconine and so on. The main ingredient, aconitine has the advantage of causing the atrial fibrillation, but, its pharmacological research has not been fully elucidated. Although there are many reports with regard to the pharmacological effects on the motility of several animal hearts, their conclusions have not been regretfully coincided yet. The authors hereby paid attention to this point of view and made experiment to examine the relationship between the alcohol extract of Korean aconitum and the motility of the isolated clam heart, making the use of several drugs related to the heart such as serotonin, acetylcholine, pilocarpine, physostigmine, barium chloride, procaine and quinidine. The cardiac movement of the isolated clam (Meretrix lusoria) heart in the standard sea water solution was recorded with the electric kymograph according to the Magnus method. The results of the experiment are as follows. 1. The motility of the isolated clam heart represents the tendency of gradual inhibition in proportion to the concentration of AK-A $10^{-4}$, $5{\times}10^{-4}$, and $10^{-3}$. 2. The cardiac inhibitory effect of AK-A $10^{-3}$ antagonizes the motility of the isolated clam heart pretreated with serotonin $10^{-6}$. 3. The cardiac inhibitory effect of AK-A $10^{-3}$ antagonizes the systolic state appealed by barium chloride $10^{-3}$. 4. The systolic state caused by quinidine $10^{-4}$ is not inhibited by AK-A $10^{-3}$.

The present study elucidated the effect of the selective inducible nitric oxide synthase (iNOS) inhibitor $N^6$-(1-iminoethyl)-L-lysine (L-NIL) on monosodium urate (MSU) crystal-induced inflammation and edema in mice feet. L-NIL (5 or 10 mg/kg/day) was administered intraperitoneally 4 h before injection of MSU (4 mg) into the soles of mice hindlimb feet. Twenty-four hours after MSU injection, foot thickness was increased by 160% and L-NIL pretreatment reduced food pad swelling in a dose dependent manner. Pretreatment of 10 mg/kg/day L-NIL significantly suppressed the foot pad swelling by MSU. Plasma level of nitric oxide (NO) metabolites and gene expression and protein level of iNOS in feet were increased by MSU, which was suppressed by L-NIL pretreatment. Similar pattern of change was observed in nitrotyrosine level. MSU increased the gene expression of tumor necrosis factor (TNF)-${\alpha}$ and interleukin (IL)-$1{\beta}$ and L-NIL pretreatment suppressed MSU-induced cytokines expression. The mRNA levels of superoxide dismutase and glutathione peroxidase1 were increased by MSU and L-NIL pretreatment normalized the gene expression. Phosphorylation of extracellular signal-regulated kinase 1/2 and p38 was increased by MSU, which was suppressed by L-NIL pretreatment. The mRNA levels of iNOS, TNF-${\alpha}$, and IL-$1{\beta}$ were increased by MSU in human dermal fibroblasts, C2C12 myoblasts, and human fetal osteoblasts in vitro, which was attenuated by L-NIL in a dose dependent manner. This study shows that L-NIL inhibits MSU-induced inflammation and edema in mice feet suggesting that iNOS might be involved in MSU-induced inflammation.

This study examined two groups of students Korean Oriental Medicine majors and Food and Nutrition majors and compared their knowledge of clinical nutrition as well as their tendency to follow healthy lifestyles. In all, 204 college juniors and seniors majoring in Food ＆ Nutrition, and 324 sophomores majoring in General Korean Oriental Medicine were given a questionnaire. Overall, knowledge of clinical nutrition(out of twenty questions) was significantly higher among the students majoring in food and nutrition (p<0.01). Specifically, these students obtained a higher score in the questions pertaining to the following topics: nutritional support(p<0.05), the relationship between menopause and blood cholesterol(p＜0.01), the relationship between weight control and carbohydrates(p＜0.01), the relationship between gout and protein(p＜0.10), the relationship between hyperlipidemia and carbohydrates(p＜0.01), the relationship between trans fatty acids and atherosclerosis(p＜0.01), the relationship between blood potassium levels and kidney disease(p<0.01), and the relationship between weight control and diet and water(p＜0.05). Conversely, students studying General Korean Oriental Medicine had a better knowledge of the relationship between malnutrition and the mortality rate and health complications(p＜0.01). The questions relating to a healthy diet and lifestyle indicated that students majoring in Food and Nutrition had higher incidences of diet irregularity and a higher missing rate (p<0.01); they were more interested in calorie content and nutrients in their diet(p＜0.05); and they were more likely to study about nutritional knowledge during their leisure time (p＜0.01). The results also indicated, however, Korean Oriental Medicine students consumed proportionally more vegetables(p<0.05); and they were more likely to take the stairs than the elevator(p＜0.01).

In this study, the antioxidant, anti-xanthine oxidase, anti-melanogenic and anti-wrinkle effects of methanol (ME) and hot water (HE) extracts from the fruiting bodies of Phellinus vaninii were investigated. The 1,1-diphenyl-2-picryl-hydrazyl free radical scavenging activity of 2.0 mg/mL HE (95.38%) was comparable to that of butylated hydroxytoluene (96.97%), the reference standard. The hydroxyl radical scavenging activities of ME (98.19%) and HE (97.55%) were higher than that of butylated hydroxytoluene (92.66%) at 2.0 mg/mL. Neither ME nor HE was cytotoxic to murine melanoma B16-F10 cells at 25-750 ㎍/mL. Although the xanthine oxidase (XO) inhibitory effects of ME and HE were significantly lower than that of allopurinol, the values were higher than 84 percent. The in vitro tyrosinase inhibitory activities of ME and HE were comparable to kojic acid at 2.0 mg/mL. The cellular tyrosinase and melanin synthetic activities of ME and HE on B16-F10 melanoma cells at 500 ㎍/mL were higher than arbutin, indicating that the inhibitory effects of arbutin on the tyrosinase and melanin synthesis were higher than those of ME and HE. The collagenase inhibitory activity of HE was comparable to EGCG at 2.0 mg/mL, however, the elastase inhibitory activity of ME and HE was lower than EGCG at the concentration tested. The study results demonstrated that the fruiting bodies of Ph. vaninii possessed good antioxidant, anti-xanthine oxidase, cell-free anti-tyrosinase, cellular anti-tyrosinase, anti-collagenase, and moderate anti-elastase activities, which might be used for the development of novel anti-gout, skin-whitening, and skin anti-wrinkle agents.

Renal failure is one of the main causes of economic impacts in the poultry industry and complex syndrome with different severity of clinical signs caused by multiple nephropathogenic factors such as infectious bronchitis viral infection and excess salt and calcium in diet. To evaluate the correlation between severity of renal failure and the causative nephropathogenic factors, one-day-old specific pathogen free chicks were treated with either single causative factor or multiple causative factors described as above. Each group was designed as control for non-treated control, IB for infectious bronchitis virus (IB virus) infection, IBHNa for IB virus infection with high diet salt, IBHCa for IB virus infection with high diet calcium, IBHNC for IB virus infection with high diet salt and calcium, HNa for high diet salt, HCa for high diet calcium and HNC for high diet salt and calcium. Chickens were inoculated with IB virus at 1-day-old and remained on their respective diets until 21 day of age. The high dietary salt feeding groups such as IBHNa, IBHNC, HNa, HNC increased water intake, watery diarrhea, general subcutaneous edema and the high dietary calcium feeding groups such as IBHCa and IBHNC showed severe visceral gout. Two more than treated groups caused high mortality in comparison with the single treated groups. IB virus exposure significantly increased urate deposition and lymphocytic interstitial nephritis. Especially urate deposition dramatically increased when excess diet calcium was combined together. In excess diet salt treated groups enlarged edematous kidneys were observed and hypertrophy of glomeruli were showed. These results suggest that IB virus enhanced the incidence and severity on chicken renal failure clearly related to the quantity of salt and calcium.
