BACKGROUND: This study aimed to evaluate the combined effects of three components (NPK) of chemical fertilizers with basal application of compost on soil organisms.METHODS AND RESULTS: The soil was treated with five treatments continuously for 15 years: control, PK, NK, NP and NPK. The application of N increased plant growth or biomass, and enhanced organic matter content in the soils. Levels of microbial phospholipid fatty acids (PLFAs) in the soils did not show marked differences among the soils treated with different treatments. However, the principal component analysis showed the changes in the structure of the microbial community in the soil, depending on treatments added. Nitrogen application caused a decrease of pH and an increase of EC in the soils, and these environmental stresses appeared to offset the promoting effect of increased organic matter content on microbial abundance. The abundance of bacterivorous nematodes was the highest in the soils after treating NPK; however, the abundance of fungivorous nematodes was unaffected. There was no significant correlation between the abundances of microbial groups and their feeders. Organic matter content was significantly correlated with the abundance of nematodes in the soils.CONCLUSION: Our results showed that chemical fertilizers affect the soil food chains through both biotic and abiotic factors, and a trophic cascade in the soils may not occur in response to long-term fertilization.

Objective: The purpose of this study is to find out the effect of acupuncture at HT7 (Shinmun) on the feeding behavior and hypothalamic neuropeptide Y(NPY) expression in the maternally separated rat pups. Methods: To show the effect of acupuncture, we performed maternal separation(MS) for 7 days beginning on postnatal day 14, and observed body weight, food intake, and NPY immunoreactivity in the paraventricular nucleus (PVN) of hypothalamus after acupuncturing at HT7, the end of the transverse crease of the ulnar wrist of the forepaw. Results: MS induced a significant decreases in body weight and food intake, while acupuncture treatment at acupoint HT7 showed much more improvement in those evaluations. NPY-immunoreactivity in area PVN were decreased in the MS group, but significantly increased in the HT7 group. Conclusions: These findings suggest that acupuncture has an effect on the feeding disorders caused by MS, possibly by modulating NPY expression in the PVN.

This study investigated the body image, body stress, eating attitude, and dietary quality in middle school girls. Questionnaires were administered to one hundred fifty seven middle school girls in Seoul area. The subjects were categorized into the five groups according to their body mass index (BMI); 1) severely under-weight (BMI < 16.5 $kg/m^2$), 2) under-weight (16.5 $\leq$ BMI < 18.5 $kg/m^2$), 3) normal weight (18.5 $\leq$ BM I < 23.0 $kg/m^2$), 4) overweight (23.0 $\leq$ BMI < 25.0 $kg/m^2$), and 5) obese (BMI $\geq$ 25 $kg/m^2$). 7.0%, 14.6%, 58.9%, 10.2%, and 10.2% of the subjects were classified as severely under-weight, under-weight, normal weight, overweight and obese groups, respectively. Regardless of the BMI, the subjects had disturbed body image, body stress, and poor eating attitude. The actual BMIs of the normal weight, overweight and obese subjects were significantly different from their desired BMI and perceived BMI, representing these subjects dissatisfied their body shape. Almost all subjects tried to lose their body weight even in the severely under-weight and under-weight groups. There were significant correlations of BMI with body image disturbance (p < 0.05), body stress (p < 0.01) and eating attitude (p < 0.05). These results indicated that middle school girls who have higher BMI seemed to have more body image distortion, body stress and risk of eating disorder. However, any significant difference in dietary quality among the five groups was not observed even though their dietary patterns were not balanced. As a conclusion, it is required that middle school girls should correct their distorted body image and body stress. Also, efforts to improve eating attitude, dietary pattern and nutritional status in the middle school girls are needed.

To find the preliminary environmental conditions for a short-time transport of living olive flounder, Paralichthys olivaceus, the stress response and physiological metabolic activity of the cultured fish to feed deprivation and slow temperature descending ($15.8^{\circ}C{\rightarrow}13.3^{\circ}C$) were monitored for 8 days. The monitored variables were the plasma alanine aminotransferase (ALT), aspartate aminotransferase (AST), glucose (GLU), total protein (TP), electrolytes ($Na^+$, $K^+$, $Cl^-$) and thyroid hormones ($TT_4$, $TT_3$, $FT_4$ and $FT_3$). In food deprivation experiment for 8 days, we did not find any statistical change of level in AST, ALT and electrolytes ($Na^+$, $K^+$, $Cl^-$), but found a significant decrease in TP and GLU. In thyroid hormones, the levels of four hormones in plasma were all showing a tendency to decrease. Especially, $FT_4$ and $TT_3$ were significantly decreased, indicating a withering of physiologic activity. In the temperature test, although no any significant change in AST, TP and electrolytes ($Na^+$, $K^+$, $Cl^-$), we observed a significant decrease of ALT and GLU following to temperature descending from $15.8^{\circ}C$ to $13.3^{\circ}C$ (P<0.05). In the levels of thyroid hormones, any significant change was not observed for experimental period. We conclude that the stress response and physiological activity of olive flounder were more influenced by feed deprivation than slow temperature descending at a transport of living fish, and plasma GLU appears to be sensitive factor to physiological metabolic activity, indicating that it could be used as a monitering mark or index for a health inspection of the fish.

Robinow syndrome is skeletal dysplasia with both autosomal dominant and recessive inheritance patterns. It is characterized by short-limbed dwarfism, abnormalities in the head and face, as well as vertebral segmentation. A 2-year-7-month old boy with Robinow syndrome had visited Seoul National University Dental Hospital, for the evaluation of tooth palatal eruption on maxilla. He had micrognathia, delayed tooth eruption, cleft lip with bifid uvula. He also had an erupted mesiodens on the palatal side of maxillary primary incisors, which was tuberculated and 8mm in major diameter. The patient was scheduled for mesiodens extraction under general anesthesia. He was a young child with delayed development, so general anesthesia was inevitable. General anesthesia was induced and maintained with inhalation agent, Sevoflurane. There were no postoperative complications related to anesthesia and dental treatment. Robinow syndrome patients have craniofacial dysmorphism and eruption disorders. Therefore, he requires regular check-ups as well as dental managements.

Cardiovascular disease is caused by different factors. These factors include innateness factors such as aging, biological factors such as high blood pressure, and environmental factors such as stress. This study examined the factors associated with cardiovascular disease and the ways to reduce its prevalence by analyzing the data within the Korean National Health and Nutrition Examination Reports from 2013 to 2017, and particularly the survey and examination data for people over 50 years old. The study population was divided into two groups: members of the first group consumed riboflavin and niacin at the recommended rate while those in the second group did not. Riboflavin intake was correlated with hypertension, hyperglycemia, and a low HDL-cholesterol level, whereas niacin intake was correlated with hypertension, hyperglycemia, waist size, and a low HDL-cholesterol level. The combination of niacin and riboflavin intakes was correlated with hypertension, hyperglycemia, waist size, and a low HDL-cholesterol level (P<0.05). The combined intake of the recommended levels of riboflavin and niacin reduced the average physiological factor abnormality rate to 80%. Taken together, the beneficial effects of riboflavin and niacin can reduce the prevalence of cardiovascular disease.

This study was carried out to investigate abiotic and biotic environmental factors affecting homoharringtonine (HHT) contents of Cephalotaxus koreana, whereby, to provide basic information of high value-added industry production of HHT as a promising anti-cancer agent. For correlation between abiotic environmental factors (soil moisture, soil pH, habitat density and temperature) and HHT contents, the contents were highly correlated with soil moisture (0.77) and soil pH (-0.68). For multiple regression analysis of relationship between abiotic environmental factors (soil moisture and soil pH) and HHT contents, soil moisture appeared to be strongly affecting the contents relatively due to being significant at only its regression coefficient ($26.48^{***}$). For the effect of biotic environmental factors (damage index) affecting HHT contents, the contents was quadratic with equation of $H=278.23+1242D-398.87D^2$, also, damage index had strong effect on the contents. Finally, for the result of the most influencing an environmental factor on HHT contents, both damage index and soil moisture were suitable in second polynomial regression, also, damage index ($R^2=0.73^{***}$) was turned out to be more influencing factor than soil moisture ($R^2=0.67^{**}$) on HHT contents relatively. Therefore, we predict that HHT contents in the trees of Cephalotaxus koreana is produced as a chemical defense mechanism triggered by a stress-related damage of fungi or insects.

This study was conducted to investigate the effects of dietary supplementation of multiple probiotics on the performance, small intestinal microflora and immune response in laying hens and broilers. In Exp.1, a total of 800, 82 wk old Hy-line Brown$^{(R)}$ laying hens were assigned to one of the following five dietary treatment; Control, Antibiotics (avilamycin 6 ppm), Probiotics; PB-M (Micro-ferm$^{(R)}$ 0.2%), PB-L (Lacto-sacc$^{(R)}$ 0.1%), PB-Y (Y University probiotics 0.2%). Each treatment was replicated eight times with 20 birds in each replicate and two birds were housed in each cage. Twenty birds units were arranged according to completely randomized block design. Feeding trial lasted 6 wk under 16 h lighting regimen. The Exp. 2, was conducted with a total of 1,000 broilers chicks (Ross$^{(R)}$). They were divided into five treatments, same as those of Exp. 1. Birds were fed starter (0~3 wk) and grower (4~5 wk) diets. Each treatment was replicated four times with 50 birds per pen comprising of deep litter. In Exp. 1, egg production parameters, such as hen-day and hen-house egg production, egg weight, broken and soft shell egg production, feed intake and feed conversion were not significantly different among treatments. However, strength and thickness of eggshell were significantly (P<0.05) different. Among the probiotics, PB-Y showed the highest strength and thickness of eggshell. Eggshell color, egg yolk color and Haugh unit were not significantly influenced. In Exp. 2, overall weight gain (0~5 wk) and mortality were not significantly different among treatments. However, weight gain of birds from PB-Y treatment during starter (0~3 wk) was significantly lower than the birds from Control and Antibiotic treatment. During the whole period (0~5 wk), birds from Antibiotics treatment had higher feed intake and Production Index (PI) and lower feed conversion than birds from Control treatment. Probiotics treatments were not significantly different from the Control on feed intake and feed conversion. In Exp.1, there were significant (P<0.05) differences in leukocytes parameters, such as white blood cell (WBC), hetrophil (HE), lymphocytes (LY), monocyte (MO), eosinophil (EO) and stress index (SI; HE/LY) in the blood of layers. Birds from Antibiotics and probiotics treatments tended to increase these parameters. In Exp. 2, however, only SI was significantly (P<0.05) decreased in Antibiotics treatments. Concentration of serum immunoglobulin (IgG) were higher (P<0.05) in PB-M and PB-Y treatments when compared with Control treatment in Exp. 1. The population of E. coli significantly (P<0.05) decreased in birds from Antibiotics, PB-L and PB-Y treatments when compared with birds from Control treatment in Exp. 1. Metalbolizability of crude fat decreased significantly (P<0.05) in birds from probiotic treatments in Exp. 2. It was concluded that the response of probiotics on the productivity of layers and broilers were different. Probiotics increased strength and thickness of eggshell in layers, and decreased feed conversion and increased PI in broilers. Leukocytes and IgG tended to increase by supplementation of antibiotics and probiotics in layers. Intestinal E. coli tended to decrease in layers. Digestibility of crude fat of diet decreased in probiotics treatments broilers. Parameters of blood and microbial were more sensitive in layers than broilers.
