Purpose : $Henoch-Sch{\ddot{o}}nlein$ purpura(HSP) is the most common and benign systemic vasculitis in children. Few reports have focused on worse outcomes of HSP in adults. The age of onset is suggested as a main risk factor. We assessed the characteristics of adolescent-onset HSP. Methods : We retrospectively analyzed 205 cases presented from Aug. 1993 to Oct. 2003. Patients were classified as children(<10 years of age), adolescents(10-20 years of age), and adults(>20 years of age). Results : The mean age was $5.7{\pm}1.8years$ in 149 children, $13.5{\pm}2.4years$ in 38 adolescents, and $44.9{\pm}14.5years$ in 18 adults. The male to female ratio was 1.2 : 1 in children and adolescents, and 2 : 1 in adults. Previous upper respiratory infections were found in 53.4 percent of children, 32.4 percent of adolescents, and 33.3 percent of adults. Positivity of stool occult blood was more frequent in adults(50.5 percent) than in children(23.0 percent)(P<0.05). Renal involvement was found in 46 cases (30.9 percent) of children, 23 cases(60.5 percent) of adolescents, and 15 cases(83.3 percent) of adults. Recurrences occurred in 23 cases(15.4 percent) of children, nine cases(23.7 percent) of adolescents, and three cases(16.7 percent) of adults. Among the cases with renal involvement, 97.8 percent of children and 87.0 percent of adolescents improved to normal or asymptomatic urinary abnormalities. 60.0 percent of adults persisted with severe nephropathy and 13.3 percent progressed to renal insufficiency. Conclusion : Although the outcome of adolescent HSP was as good as children, the clinical manifestations were similar to those of adults. Adolescents had the highest rate of recurrences. Thus long term observations may be needed in adolescent onset HSP.

Glycogen storage disease (GSD) and mucopolysaccharidosis (MPS) are both independently inherited disorders. GSD is a member of a group of genetic disorders involving enzymes responsible for the synthesis and degradation of glycogen. GSD leads to abnormal tissue concentrations of glycogen, primarily in the liver, muscle, or both. MPS is a member of a group of inherited lysosomal storage diseases, which result from a deficiency in specific enzymatic activities and the accumulation of partially degraded acid mucopolysaccharides. A case of a 16-month-old boy who presented with hepatomegaly is reported. The liver was four finger-breadth-palpable. A laboratory study showed slightly increased serum AST and ALT levels. The liver biopsy showed microscopic features compatible with GSD. The liver glycogen content was 9.3% which was increased in comparison with the reference limit, but the glucose-6-phosphatase activity was within the normal limit. These findings suggested GSD other than type I. Bony abnormalities on skeletal radiographs, including an anterior beak and hook-shaped vertebrae, were seen. The mucopolysaccharide concentration in the urine was increased and the plasma iduronate sulfatase activity was low, which fulfilled the diagnosis criteria for Hunter syndrome (MPS type II). To the best of the authors' knowledge, this is the first case of GSD and Hunter syndrome being identified at the same time.

In Concentrated Animal Feeding Operations(CAFOs), emission of ammonia from stored manure contributes negatively on the wellness of livestock. In CAFOs facilities, indoor aerial ammonia concentration oftentime surpasses the critical level potentially harmful to livestock's immune system. Understandably, numerous researches to control aerial ammonia have been conducted in countries where CAFOs were practiced for many decades. Some innovative technologies, such as scrubber, bio-filter, and additives emerged, as a result. Among them, microbial additives became popular in Korea, due to an easiness of use and affordability. However, microbial additives still have some weaknesses. Their price is still high enough to discourage farmers who run a small scale farm and their effectiveness are still questioned by many users and researchers. In the present study, we found soluble carbohydrates, such as sugar, glucose, and molasses, when supplemented to pig slurry manure, can mitigate ammonia emission. To be more specific, pig manure slurry(120kg), stored in container(200L), was supplemented with sugar at 0.1%(w/w) and was, subsequently, monitored for pH and aerial ammonia for next 10 days. From this experiment, it was found that the sugar supplementation was effective in mitigating the aerial ammonia concentration (33% in average) when monitored daily. Also, the pH of manure slurry was maintained at relatively low level(8.2) in sugar-supplemented manure slurry while it was elevated to 8.5 in untreated slurry. Conclusively, the obtained data suggest that soluble carbohydrate can mitigate ammonia emission by acidifying manure slurry. Additionally, it can be suggested that soluble carbohydrates, such as sugar, glucose, and molasses, can be reasonable choices for animal farmers who have been looking for an alternative choice to replace expensive microbial additives.
This experiment was conducted to investigate the effects of dietary supplementation of fermented apple pomace (FAP) and cinnamon on laying performance, egg quality and blood characteristics in laying hens. A total of two hundred 57-wk-old Hy-Line laying hens were divided into five groups with 4 replicates of 10 birds each; control, 0.1% probiotics, 1.0% fermented apple pomace 1.0%, 0.1% cinnamon and 1.0% fermented apple pomace with 1.0% cinnamon. Chickens fed the diets containing 1.0% of fermented apple pomace showed higher egg production than the chickens fed the other diets. No synergic effect on laying performance was found when fermented apple pomace and cinnamon were added to the diets in laying hens. There was no significant major differences in egg quality and serum blood biochemical profiles. These results suggest the possibility that fermentation of apple pomace could be used as the alternative of antibiotic growth promoters.

This experiment was conducted to investigate the effect of dietary supplementation of yellow loess on performance and blood component profile in broiler chickens. A total of three hundred sixty, 1 day old broiler chicks (Ross) were randomly divided into 3 groups with 4 replicates of 30 birds each. The experiment feeds were; control (basal diet), 0~10 days (basal diet with yellow loess T1 4%, T2 2%), 11~21 days (basal diet with yellow loess T1 2%, T2 1%), 22~35 days (basal diet with yellow loess T1 1%, T2 1%). The body weight and weight gain of the broilers fed T2 diet was significant higher than the T1 and control treatment (P<0.05). Feed intake was significantly higher than the control during overall period (P<0.05). Total cholesterol in all yellow loess supplemented treatments were significantly higher than the control treatment (P<0.05), and the triglyceride of broiler fed the diet containing T1 was significantly higher than the control and T2 treatment (P<0.05). No significant differences were observed on the total white blood cell (WBC), neutrophil (NE), monocyte (MO) and eosinophil (EO) in all yellow loess supplemented treatments compared to the control. Lymphocyte of T2 treatment was significantly higher than T1 and control treatment (P<0.05). No significant difference was observed on fecal ammonia gas emission, but broiler fed yellow loess was lower than the control treatment. Aa a result, dietary supplementation of yellow loess was improve to weight gain and feed intake of broiler.
Oyster shell has a high content of $CaCO_3$ to be used as a acidic soil amendment. To enhance productivity of barley and soil microbe in an upland soil, oyster shell and calcium-magnesium carbonate were selected as a soil amendments in this study. A field experiment was treated no treatment (hereafter, control), oyster shell lime $3.09Mg\;ha^{-1}$ and $2.38Mg\;ha^{-1}$, and calcium-magnesium carbonate $2.38Mg\;ha^{-1}$ as amount of lime requirement in silt loam soil. The yield of barley from the oyster shell lime treatment was the highest. The protein content of barley was the highest of 11.1% in the calcium-magnesium carbonate, followed by 10.7% for the control, 10.6% for the oyster shell lime $3.09Mg\;ha^{-1}$, and 10.4% for the oyster shell lime $2.38Mg\;ha^{-1}$. Soil pH value was higher than that of control in harvesting stage. In addition, the population of soil bacteria was highest in oyster shell lime $2.38Mg\;ha^{-1}$, actinomycetes was highest in calcium-magnesium $2.38Mg\;ha^{-1}$. We concluded that the oyster shell lime can be effective to restore soil nutrient and microbe balance in an upland soil.
The multiclass pesticide multiresidue method for the simultaneous determination of diflubenzuron in agricultural products was conducted by using HPLC-UVD. The method was validated through the guidelines of linearity, specificity, limit of detection (LOD), limit of quantification (LOQ), accuracy and precision with pesticide-free spinach, Korean cabbage, eggplant, squash, sweet pepper, cucumber, Korean melon. The calibration curve of diflubenzuron was linear over the concentration range of 0.05-5 mg/kg with correlation coefficient of above 0.99999. The limit of detection and quantification was 0.008 and 0.02 mg/kg. Mean recoveries of diflubenzuron for each sample were 77.5-105.6%. Relative standard deviation (RSD) in recoveries were all less than 20%. The intra-day and inter-day precision (RSD) were 0.4-1.9% and 0.7-1.9%, respectively. The result of validation indicated that this method was accurate and rapid assay.
This study was conducted to provide basic data of Cirsium setidens Nakai in different harvest time that will be applied for development of functional foods and ingredients. We investigated pectiolinarin and pectolinarigenin content, total flavonoids content and antioxidant effects (DPPH radical scavenging activity and ORAC assay) of C. setidens Nakai. Our results showed that the pectolinarin and total flavonoids contents of C. setidens Nakai in harvesting time ranged from $43.13{\pm}0.22$ to $95.65{\pm}0.34mg/g$ and from $32.81{\pm}1.68$ to $40.43{\pm}0.35mg$ rutin equivalent (RE)/g, respectively. The DPPH radical scavenging activity of C. setidens Nakai did not show differences in harvesting time. The oxygen radical absorbance capacity (ORAC) value was highest in August (2016) extracts ($827.72{\mu}mole\;TE/g$). In addition, C. setidens Nakai exthanolic extract in harvesting time did not show any cytotoxicity up to $200{\mu}g/mL$. During adipocyte differentiation, C. setidens Nakai extract in harvesting time significantly inhibited lipid accumulation and ROS production, compared with the controls. These results suggest that C. setidens Nakai extract could be considered as a non-toxic natural resources of functional food ingredients and natural antioxidants.
Purpose : Bacteremia in immunocompromised pediatric cancer patients can lead to high morbidity and mortality, if not treated early and properly. The incidence and antibiotic sensitivities to common pathogens of bacteremia in pediatric cancer patients are liable to change, according to region and time. We investigated the causative organisms and antibiotic sensitivities of bacteremia in pediatric cancer patients to assess the adequacy of empiric antimicrobial therapy. Methods : From September 1995 to August 2003, we retrospectively evaluated 58 episodes in 39 pediatric cancer patients with bacteremia treated at the Pediatric Department of Yeungnam University Hospital. We investigated and analyzed the causative organisms and the antibiotic sensitivity test results by reviewing the records of the microbiologically proven positive blood culture results. Results : The incidence of bacteremia in pediatric cancer patients in this study was 5.7 percent (58 episodes out of 1,022 occasions of blood cultures). Gram-positive organisms were isolated more often than gram-negative organisms (63.8 percent vs 36.2 percent) in the following order : Staphylococcus epidermidis (37.9 percent), Staphylococcus aureus (17.3 percent), Escherichia coli (12 percent), Streptococcus (8.6 percent), Enterobacter (6.9 percent), Klesiella (6.9 percent), Serratia (3.5 percent), Acinetobacter (3.5 percent), Proteus (1.7 percent) and Morganella morganii (1.7 percent). In antibiotic sensitivity tests, only six of 37 isolates (16 percent) of gram positive bacteria were sensitive to penicillin and 15 of 37 isolates (40 percent) were sensitive to oxacillin. All except one Staphylococcus aureus were sensitive to vancomycin and all except one Staphylococcus epidermidis were sensitive to teicoplanin among 37 isolates of gram positive bacteria. In the case of gram negative bacteria, two of 21 isolates (10 percent) and four of 21 isolates (19 percent) were sensitive to cefotaxime and ceftazidime, respectively. Only six of 21 isolates (29 percent) were sensitive to aminoglycoside, but all 21 isolates (100 percent) were sensitive to imipenem. All seven isolates tested after the year 2000 were sensitive to meropenem. Conclusion : In conclusion, we should choose the proper antimicrobials in treating pediatric cancer patients with suspected bacteremia, reflecting the increasing episodes of gram positive bacteremia and polymicrobial resistance of gram positive and negative organisms.
Kojis were prepared from the different starch raw materials such as glutinous rice, barley rice, wheat flour and sweet potato, and were tested in an effort to reduce production cost and to improve quality of Kochuzang(red pepper paste). During the starting period of Koji preparation, there were less significant changes in pH; however, pH decreased somehow in the case of sweet potato, whereas it increased for the other Kojis. In general, the highest acidity was obtained after 72 hours of Koji preparation. Total nitrogen, soluble nitrogen and amino-nitrogen content increased in order of wheat flour, barley rice, and glutinous rice; Kojis they were markedly produced between 72 and 96 hours of Koji preparation. The maximum amount of reducing sugar was observed between 48 and 72 hours of Koji preparation during this period the reducing sugar content varied widely depending on starch source. Sweet potato Koji produced the highest level of ethyl alcohol content after 72 hours of Koji preparation; for the other Koji the same trends were observed after 24 hours. The starch liquefying activities have reached the highest level after 96 hours and for glutinous rice and barley rice; however, they kept on increasing until 120 hours for wheat flour and sweet potato. Koji Starch liquefying and saccharogenic amylase activities tended to increase in order of sweet potato, glutinous rice, barley rice and wheat flour. Kojis Various protease activities were measu-red during the Koji preparation, and they increased in order of alkali, neutral and acidic protease.
