  • The purpose of this study was to investigate the effect of ground corn as an additive to ginseng residue silages. The silages were made with corn (CS), red ginseng (GS), red ginseng residue +0.5% ground corn (GS0.5), w/w bases, red ginseng residue+1.0% ground corn (GS1.0) and red ginseng residue+silage inoculant, lactic acid bacteria (GSL). The raw materials were cut only for corn forage in 2cm length. The ginseng residue without cutting were mixed without or with additives, ground corn and inoculant, and ensiled each into two 2,000ml glass bottles. The bottles with silages were stored at a dark place at room temperature and formented for 60 days. The crude protein contents were higher for all red ginseng silages as 17.7, 18.8, 18.3 and 17.8% for GS, GS0.5, GS1.0 and GSL than that of corn silage as 8.8% (p<0.05). The calcium content were higher in GS, GS0.5, GS1.0 and GSL as 0.99, 1.13, 0.99 and 1.03% than that in CS as 0.31% (p<0.05). The pH of silages fermented for 60 days was similar each other; CS, GS, GS0.5, GS1.0 and GSL as 3.8, 3.7, 3.3, 3.5 and 3.7, respectively. However the pH of GS0.5 was the lower than that of corn silage. The total concentration of volatile fatty acids were higher for CS as 87.3 mM/dl than those of GS, GS0.5, GS1.0 and GSL as 44.7, 37.8, 46.3 and 47.2 nM/dl. However, the percentage of lactic acid concentration of ginseng silages such as GS, GS0.5, GS1.0 and GSL, 60.2, 77.2, 83.4 and 77.3% was higher than that in CS, 53.7% (p<0.05). The in vivo dry matter digestibilities for 72hr fermentation was higher in ginseng silages (GS, GS0.5, GS1.0 and GSL as 76.5, 75.8, 72.9 and 77.3%, respetively) than that in for CS as 52.1% (p<0.05). It can be concluded that silage added with ground corn (GS0.5 and GS1.0) and lactic acid inoculant were high in its quality, and the GS0.5 can be suggested as a practical method for red ginseng residues silage making.

  • The muscle extracts of the ascidian, Halocynthia roretzi cultured for two and three years old on the southern coast near Chungmu and the eastern coast near Pohang of Korea, were analyzed for extractive nitrogen (EN), free amino acids (FAA), combined amino acids (CAA), nucleotides and related compounds (NRC), quaternary ammonium bases and guanidino compounds using specimens collected in February 1989 and in April 1989, and compared for those contents with each other. As for the amount of EN, no remarkable difference was found between two- and three-year-old samples collected at St. 1 in the spring and winter seasons, while at St. 2 in the spring season the two-year-old sample was distinctly lower than the three-year-old one. Taurine, proline, glutamic acid, glycine and alanine were the major FAA in every sample. The amount of taurine, the most prominent FAA, was higher in three-year-old sample than in two-year-old one regardless of sampling station and season. Most of the other major FAA showed a similar tendency to EN at both sampling stations in both seasons. Adenosine 5'-triphosphate (ATP), adenosine 5'-diphosphate (ADP), adenosine 5'-monophosphate (AMP), inosine 5'-monophosphate (IMP), inosine (Ino) and hypoxanthine (Hyp) were detected in all the samples and ATP, ADP and AMP were the major ingredients. The amounts of total NRC were in parallel with those of EN and total FAA. As for the contents of betaines, two- and three-year-old samples collected in the winter season exhibited a great discrepancy each other, the former being clearly lower than the latter, but no remarkable difference was observed between two samples of two groups in the spring season. In proximate composition of the muscles, the two-year-old sample was considerably higher in moisture content and lower in protein and glycogen contents than the three-year-old one at St. 2 in the spring season. The large discrepancies observed between two- and three-year-old samples from St. 2 seems to be attributable to the difference in size of samples rather than to the difference in age.

  • Purpose: Laparoscopy-assisted gastrectomy (LAG) is gaining wider acceptance as a minimally invasive treatment for early gastric cancer, but the safety, efficacy and clinical benefits of this type of surgery are still unclear. The purpose of this study is to compare laparoscopy-assisted gastrectomy (LADG) and conventional open distal gastrectomy (CODG) for early gastric cancer (EGC) according to the changes of the postoperative nutritional status and acute inflammatory reaction. Materials and Methods: Eighty seven patients with EGC and who underwent a LADG between March 2006 and May 2009 at Daegu Catholic University Hospital, was enrolled. Over the same period, we enrolled 30 patients who underwent CODG and they were confirmed to have EGC from their pathology. The clinico-pathological features and serologic parameters were evaluated from the medical records and then retrospectively analyzed. Results: There were no differences in the preoperative white blood cell (WBC), C-reactive protein (CRP) level, albumin level, the T4/T8 ratio and the other clinical data between the two groups. The total WBC counts gradually increased and they were significant lower at the $1^{st}$ and $3^{rd}$ postoperative days in the LADG group than that in the CODG group (P=0.001 and 0.008, respectively). The postoperative CRP levels were significantly lower at postoperative $5^{th}$ day in the LADG group (P<0.001). The postoperative albumin and T4/T8 ratio gradually decreased, and the T4/T8 ratio was significantly higher at the $3^{rd}$ postoperative day in the LADG group compared to that in the CODG group (P=0.003). Conclusion: This study demonstrates that the LADG has less of an influence on an acute inflammatory reaction than does CODG. Therefore, it is one of the safe and feasible procedures for the treatment of early gastric cancer.

  • Nutritional compositions of acorn crude starch were analyzed according to country of origin, especially the mineral and sugar contents. Regarding the three kinds of starch of domestic (South Korea, KAS), Chinese (CAS), and North Korea (NAS) origins in the Korean market, NAS had the lowest moisture content as well as the highest contents of crude protein, crude fat, and carbohydrate. Regarding mineral contents, NAS contained the highest amounts of magnesium, calcium, sodium, potassium, and phosphorous, whereas CAS contained the highest iron and zinc contents. There were no significant differences in acidity and pH. Analysis of the monosaccharide contents of the starches showed that glucose was the highest in KAS while sucrose was the highest in CAS. The Hunter color L value was the lowest in NAS, whereas a and b values were the lowest in CAS. Total phenolic content was the highest in NAS. NAS had the highest DPPH and hydroxyl radical scavenging activities ($IC_{50}$: 47.0 mg/mL for DPPH, 0.038 mg/mL for hydroxyl) whereas KAS had similar DPPH ($IC_{50}$: 73.7 mg/mL for CAS, 86.8 mg/mL for KAS) and hydroxyl radical activities ($IC_{50}$: 0.041 mg/mL for CAS, 0.044 mg/mL for KAS) as compared to CAS.

  • The purpose of this study is to complish a method of fish glue malting with residual products such as fish head and skin discarded from sea food processing. Using the skins of Alaska pollack and file fish from fillet packers, the optimum conditions of skin glue processing were investigated and physical and chemical properties of the product were also determined. The yields of Alaska pollack, Thelagra calcogramma, skin and file fish, Novodon modestus, skin to the total body weight were $4.6\%\;and\;5.0\%$ respectively. The optimum conditions for a $49.3\%$n yield Alaska pollack skin glue processing were considered the extraction of previously tinted in $0.1\%$ calcium hydroxide solution for 3 hours with the additional water as much as 3 times of sample weight at $70^{\circ}C$ for 3 hours under the controlled pH 5.0. The conditions for file fish skin glue were similar to those of Alaska pollack except the addition of five times of water to the weight of sample skin needed for extraction. The content of crude protein of Alaska pollack and file fish skin glue were $98.0\%\;and\;96.0\%$ respectively. The contents of crude ash and crude lipid were not different from that of chemical grade gelatin. Relative viscosity, melting point, gelation temperature and jelly strength of Alaska pollack skin glue marked 5.84, $21.8^{\circ}C,\;7.1^{\circ}C\;and\;10.0g$ respectively and those of file fish skin glue showed $5.79,\;25.0^{\circ}C,\;7.4^{\circ}C\;and\;11.6g$ respectively.The color and turbidity of Alaska pollack skin glue are slightly superior to those of file fish skin glue. It is supposed that the extract residue of skin glue is valuable for use the animal feeds by the results of amino acid composition. And the ratio of each amino acid content to the total amino acid of Alaska pollack and file fish skin glue is similar to that of chemical grade gelatin.

  • Purpose : Urinary tract infection (UTI) is a common bacterial infectious disease in childhood. Especially UTI in infant and young children is associated with urinary tract anomalies such as hydronephrosis, vesicoureteral reflux. The aim of this study was to compare the clinical and laboratory characteristics, and uroradiologic findings of UTI caused by pathogens other than E. coli with UTI caused by E. coli in infant and young children. Methods : We retrospectively reviewed medical records of 170 infants and children, who had been admitted for UTI to Il Sin Christian Hospital from January 2003 to December 2005. All patients were divided into two groups; E. coli and non-E. coli UTI, and they were compared for demographic data, clinical data (degree and duration of fever, time to defervescence, and length of hospital stay), underlying urinary tract anomalies (by history and ultrasonography), recurrent infection (by history and past medical records), and laboratory data [urinalysis, white blood cells (WBC) count in peripheral blood, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and serum creatinine level]. Results : Of the 170 UTI patients, the number of non-E. coli UTI was 114 (67.1%) and E. coli UTI was 56 (32.9%). As compared to E. coli group, non-E. coli group was younger in age ($0.52{\pm}0.59years$ vs $0.84{\pm}1.39years$, P<0.05), had higher rates of urinary tract anomalies [n=46 (82.1%) vs n=53 (46.5%), P<0.001], higher recurrence rate, shorter time to defervescence, less peripheral blood WBC count, lower level of CRP, lower level of ESR. Conclusion : The characteristics of non-E. coli UTI compared to E. coli UTI was younger age, milder clinical symptoms and signs, higher rates of urinary tract anomalies and higher recurrence rate.

  • Recently, the importance of toxoplasmosis is raised as a complication in immunosuppressed or AIDS patients. Our study focused on the identification of a variety of Toxoplasma antigens by immunoblotting. Rabbits and BALB/c mice were immunized with Toxoplosmo Iysate (RH strain) , frozen tachyzoites (RH strain) or cysts (Beverly and Fukaya strain) . Blood were collected from ear vein, heart or orbital plexus for detecting the serum antibody levels. For excretory-secretory (E.S) antigens, T gondii (RH) tachyzoite were cultured in CHL (Chinese hamster lung) cells with MEM containing of 5% FCS. After 72hrs, culture supernatant was collected. BALB/c mice were inoculated with RH tachyzoite intraperitoneally and peritoneal fluids were extracted three days later. E.S antigens were detected in culture supernatant and infected mouse peritoneal fluid by EITB. Serum IgG levels in rabbit were 1 :512 of 10 days after primary immunization, 1 : 2,048 of 10 days after secondary immunization, 1: 1,024 of 20 days after secondary immunization by IFAT, respectively. Serum IgG levels of immunized mice were 1:128 after 7 weeks. Tachyzoite antigens of the RH strain were detected 25 protein bands ranging 10 kDa-220 kDa of molecular weights with Coomassie blue stain. Toxoplcsma major antigens corresponding to n of 24 kDa, 27 kDa,30 kDa, 35 kDa, 38 kDa were recognized by IgG and IgM antibodies. Excretory-secretory antigens present in culture supernatant with M. W. of 20, 30 kDa and in infected mouse peritoneal fluid with M.W. of 33 (P30), 45 kDa. When RH tachyzoite antigen was probed with different mice sera immunized with 2 strains of T gondii, the IgG antibody bud of Fukaya and Beverly strain (8 week-serum) is identical to those of RH strain. It is considered that the 30 kDa polypeptide detected in excretory- secretory materials and Iysate was important major antigen of T gondii (RH).

  • Purpose : To evaluate the prevalence of vesicoureteral reflux (VUR) according to the timing of voiding cystourethrography (VCUG) in infantile urinary tract infection (UTI). Methods : The data of 134 infants (1-12 months) with renal cortical defect in $^{99m}Tc$-2, 3-dimercaptosuccinic acid ($^{99m}Tc$-DMSA) scan with a diagnosis of UTI in two hospitals from 2000 to 2010 were retrospectively analyzed. The VCUG was performed after 2 weeks from the diagnosis of UTI in Group I (n=68), and the VCUG was performed within 2 weeks from the diagnosis of UTI in Group II (n=66). Results : There were no significant differences between the two groups in the duration of fever, white blood cell count, C-reactive protein levels, and abnormalities in ultrasonography (P>0.05). There was no significant difference between the two groups in the prevelence of VUR, bilateral VUR, and severe VUR. VCUG-induced UTI was detected 16 (23.5%) of patients in whom the procedure was performed 2 weeks after the diagnosis, and none of VCUG-induced UTI occurred in those in whom the procedure was performed 2 weeks within the diagnosis. Conclusion : We conclude that the prevalence of VUR according to the timing of VCUG did not differ between the two groups in infantile UTI with renal cortical defect in DMSA scan. We also found that performing VCUG with antibiotics can decrease risk of VCUG-induced UTI.

  • This experiment was conducted to study the spring productivity and feeding value of hairy vetch varieties. We also measured DM yield and feeding value by analyze CP and CF that authors made possible to calculate TDN and RFV. The results can be summarized as follows; Dry matter yield were increased earlier autumn seeding date and later cut in spring. Differences of dry matter yield in earlier cut in spring was high in order of Ostsaat, Welta, Vv4712, Penn-02, Common and Minnie. Crude protein(CP) yield was increased when earlier autumn seeding date and later cut in spring. Total digestible nutrient(TDN) yield of hairy vetch varieties was decreased when later autumn seeding date, and was increased when later cut in spring. TDN yield was highest in Ostsaat and Welta varieties had highest dry matter yield. Acid detergent fiber(ADF) content was decreased when later autumn seeding date and was increased when later cut in spring. Neutral detergent fiber(NDF) content was decreased when later autumn seeding date. Average values for relative feed value(RFV) were 157% and 132% in both cut. It shows that a high feed value in all of hairy vetch varieties. Above all, the results presented that the optimal seeding date for cultivating hairy vetch in the central region of Korea is between the 10th to the 20th of September. Because Ostsaat and Welta had significantly high dry matter yield we expected Ostsaat and Welta have a higher wintering ability.

  • This study was carried out to select a proper forage crop, and to estimate the proper level of application of cattle manure and carrying capacity of organic livestock per unit area. Corns and forage sorghum hybrids were cultivated with different types of livestock manures and different amount of them to produce organic forage. For both corns and forage sorghum hybrids, no fertilizer plots had significantly (p<0.05) lower annual dry matter (DM), crude protein (CP) and total digestible nutrients (TDN) yields than those of other plots, whereas the N-P-K (nitrogen-phosphorous-kalium) plots ranked the highest yields, followed by 150% cattle manure plots and 100% cattle manure plots. DM, CP and TDN yields of in cattle manure plots were significantly (p<0.05) higher than those of no fertilizer and P-K (phosphorous-kalium) plots. The yields of in cattle slurry plots tended to be a little higher than those of in composted cattle manure plots. Assuming that corn and forage sorghum hybrids produced from this trial were fed at 70% level to 450kg of Hanwoo heifer for 400g of average daily gain, the carrying capacity (head/year/ha) of livestock ranked the highest in 150% cattle slurry plots (mean 6.0 heads), followed by 100% cattle slurry plots (mean 5.3 heads), 150% composted cattle manure plots (mean 4.7 heads), 100% composted cattle manure plots (mean 4.4 heads), and no fertilizer plots (mean 2.8 heads) in corns (or the cultivation of corns). Meanwhile, in the case of forage sorghum hybrids, 150% cattle slurry plots (mean 6.4 heads) ranked the highest carrying capacity, followed by 150% composted cattle manure plots (mean 4.8 heads), 100% cattle slurry plots (mean 4.4 heads), 100% composted cattle manure plots (mean 4.1 heads), and no fertilizer plots (mean 2.8 heads). The results indicated that the application of livestock manure to cultivated soil could enhance not only DM and TDN yields, but also the carrying capacity of organic livestock as compared with the effect of chemical fertilizers. In conclusion, the production of organic forage with reutilized livestock manure will facilitate the reduction of environmental pollution and the production of environmentally friendly agricultural products by resource circulating system.
