  • Surface proteins of Trichomonqs unginnlis (T vqsinalis) were analyzed to study the antigenic variation. The surface proteins of protozoa were labelled by N- hydrokysuccinimide-biotin (NHS-biotins, the NHS-biotin-labelled proteins were immunoprecipitated with rabbit antiserum to purifjr the antigenic fractions and analysed by SDS-PAGE plus electroblotting. The results obtained in this study were as follows; Biotinylated T. uaginalis-proteins obtained from intact cell and cells disrupted prior to labelling were detected by antibiotin-peroxidase in Western blots. Labelled proteins were immunoprecipitated by T. vcqinalis-immunized rabbit serum and the six bands with, the molecular weights of 46, 60, 68, 90, 130 and 220 kDa were identified as having antigenicity. T unginalis HY-1,HY-15 and ATCC 50148 were immunoprecipitated by immune rabbit serum after biotinylation and there were no difference from antigenic bands among these strains by this tehchnique. In conclusion with the results obtained in the present study, it was assumed that surface proteins of T vaqinclis were labelled by biotinylation and the six labelled bands at 46, 60, 68, 90, 130 and 220 kDa in their molecular weight were identified as having antigenicity by immunoprecipitation (IPI and this biotinylation-IP technique may be used for further study of surface antigen of T vaginalis.

  • Soybean meal(SMB) has not only been an important source of protein, but also a major source of isolfavones(IF) for poultry diet. Since the IF is one of effective phytoestrogens, evaluation of bioavailability of the phytochemicals for poultry and development of an animal model for assessment of the availability should be essential for its practical application. Present study was to develop bird model for assessing their bioavailability. No reports for such measurments with poultry could have every been found. Eight, 6-wk-old, layer-type, male birds were divided into two groups of four birds; normal (N) and colostomized(COL). Each bird was tube-fed a SMB sample at a level of 1% body weight. Samples from blood, urine and feces(COL birds) or urine+feces (N) were collected at 0, 2, 8, 15, 24 and 48 hours after the feeding. Plasma and urine samples were treated with -glucuronidase and fecal samples with 4N HCl for measurement of genistein(GE) and daidzein (DA) with HPLC set with an electrochemical detector. Maximum peaks of plasma IF appeared at 2 h after the meal for both birds groups. However the IF peak for N group was GE, while that for COL group was DA. Plasma DA levels for COL birds were always higher than those of GE, which was in opposite trend for N birds. This trend observed in the N birds is in accordance with those reported in rats fed SBM. In conclusion the results seem to suggest that colostomy as an attempt to separate urine from feces in birds affected the IF metabolism in the intestine and may not be a proper bird model to measure the IF bioavailability.

  • Objectives : It has been suggested that obesity in childhood may lead early menarche and rapid bony maturation. The purpose of this study is to investigate correlation between bone maturation and obese degree in childhood in Korea. Methods : Height, body weight, BMI, percent body fat were taken 138 patients. Ultrasonic scan was taken through calcaneous of the right foot to evaluate bone age. $DA({\Delta}age)$ was calculated from the difference of bone age and chronological age, and it was used in correlation with obese degree. Results : 1. The average age of patients was $11.91{\pm}2.86$ years old in boys, $11.44{\pm}2.27$ years old in girls. 2. The average BMI was $20.92{\pm}4.53kg/m2$ in boys, $19.76{\pm}4.05kg/m2in$ girls, and average percent body fat was $25.13{\pm}8.23%$ in boys, $27.66{\pm}5.95%$ in girls. 3. The average OI(osteo index) was 37.88 in boys, 36.64 in girls, and average bone age was $12.00{\pm}2.61$ years old in boys, $11.81{\pm}2.11$ years old in girls. 4. There was significant correlation between $DA({\Delta}age)$ and PBF in boys, but no significant correlation with BMI(p<0.05). 5. There was significant correlation between $DA({\Delta}age)$ and PBF, BMI in girls(p<0.01). 6. There was significant correlation between RA and OI(p<0.01). Conclusion : It is suggested that obese degree may have an impact on early bony maturation especially in case of girls.

  • This research was conducted to investigate changes in quality characteristics of gamma-irradiated chickens during storage at different temperature and periods. In heme pigment(myoglobin) content, metmyoglobin content of chicken stored at 5$^{\circ}C$ was not affected by gamma irradiation but slightly increased with the increase in storage period. All samples stored at -20$^{\circ}C$ were no different in heme pigment content between nonirradiated and irradiated samples and slightly decreased as the freezing storage period increased. The SDS electrophoresis patterns were not significantly different between nonirradiated and irradiated samples. All samples stored in at 5$^{\circ}C$ showed a prominent breakdown of molecular weights ranging from 97,000 to 116,000 Daltons after 8 weeks' storage. TBA values increased according to the increment of irradiation dose level and storage period at both temperatures, 5$^{\circ}C$and -20$^{\circ}C$. However, The acid value decreased with increasing irradiation dose level. In the VBN value, nonirradiated chickens were four times higher than that of 7 kGy-irradiated one.

  • The objective of this study was to evaluate the nutritional content of bullfrog meat from different parts of the animal, including fore-chest, thigh and calf. Bullfrog meat was found to be a rich source of proteins, essential amino acids and minerals, but with a low fat content, compared with other aquatic meat products. There was no significant difference (p>0.05) between thigh and calf in mineral content (K, P, Na, Mg, Ca, Zn, Fe, Cu, and Mn), but the contents of K, P, and Mg were higher in thigh and calf than in the fore-chest (p<0.05). The salt-soluble, water-soluble and insoluble protein bands in sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) electrophoresis, from fore-chest, thigh and calf were similar, with the most abundant bands being 35 kDa (salt-soluble protein), 35-48 kDa (water-soluble protein) and 48 kDa (insoluble protein). The results showed that the insoluble protein content in the fore-chest meat was higher than that in the thigh meat and calf meat, but the salt-soluble protein fraction was the most abundant in thigh meat. These results showed that the nutrients in different parts of bullfrog meat were different.

  • This study examines the process of the introduction of stupa, which has originated in India, to the Xinjiang Uyghur region and the features of the stupas in the Xinjiang Uyghur region in detail. This study examines the layout of the buildings in temple compounds and the types, structural elements, and construction methods of the stupas in the Xinjiang Uyghur region in particular by looking into the content of the Da Tang Xi Yu Ji and remaining stupas, which provide examples of stupas at the time. This study finds that due to the characteristics of dry deserts, stupas in Xinjiang Uyghur region, where assimilation between Eastern and Western cultures is seen, were mostly made by pressing clay into a mold and had no interior spaces. Also, construction materials and techniques had been developed and improved in a way that enabled stupas to combat the challenging desert conditions. However, the stupas in this region differed significantly from the wooden tower-like stupas discovered in central China(zhongyuan 中原). The shape of the dome of most stupas in Xinjiang Uyghur region was chosen under the influence of the Gandharan style. Some of the stupas in the region have taken the general forms of the wooden stupas and the others have taken many forms, from cylindrical drums to towers. Also, there have been forests of stupas and stupas similar in form to chaityas and stupas of Vajrayana. Such different forms were transformed and modified through regional history and it was related to the peoples and cultures that produced and used stupas. Stupas evolved into distinct forms in Xinjiang Uyghur region in this way.

  • Cucumber fruit mottle mosaic tobamovirus (CFMMV) causes severe mosaic symptoms with yellow mottling on leaves and fruits, and occasionally severe wilting of cucumber plants. No genetic source of resistance against this virus has been identified. The genes coding for the coat protein or the putative 54-kDa replicase were cloned into binary vectors under control of the SVBV promoter. Agrobacterium-mediated transformation was peformed on cotyledon explants of a parthenocarpic cucumber cultivar with superior competence for transformation. R1 seedlings were evaluated for resistance to CFMMV infection by lack of symptom expression, back inoculation on an alternative host and ELISA. From a total of 14 replicase-containing R1 lines, 8 exhibited immunity, while only 3 resistant lines were found among a total of 9 CP-containing lines. Line 144 homozygous for the 54-kDa replicase was selected for further resistance analysis. Line 144 was immune to CFMMV infection by mechanical and graft inoculation, or by root infection following planting in CFMMV-contaminated soil. Additionally, line 144 showed delay of symptom appearance following infection by other cucurbit-infecting tobamoviruses. Infection of line 144 plants with various potyviruses and cucumber mosaic cucumovirus did not break the resistance to CFMMV. The mechanism of resistance of line 144 appears to be RNA-mediated, however the means is apparently different from the gene silencing phenomenon. Homozygote line 144 cucumber as rootstock demonstrated for the first time protection of a non-transformed scion from soil inoculation with a soil borne pathogen, CFMMV.

  • While simultaneous bilateral partial nephrectomy with a conventional multiport robot has been consistently reported since the 2010s, the introduction of the DaVinci SP system (Intuitive Surgical, Sunnyvale, CA, USA) could provide a novel way to perform surgery on bilateral kidneys while innovatively reducing the number of incisions. In our first report worldwide, the patient with bilateral small renal mass (2.0 cm for the left and 1.5 cm for the right side) and preoperative normal renal function was placed in the lateral decubitus position on an inverted bed. After tilting the bed to be as horizontal as possible, a 4-cm incision was made in the lower part of the umbilicus for the floating trocar technique. The partial nephrectomy was performed reliably as with the conventional transperitoneal approach, and then the patient could be repositioned to the contralateral side for the same procedure, maintaining all trocars. Total operation time (skin to skin), total console time, and the left- and right-side warm ischemic times were 260, 164, 27, and 23 minutes, respectively, without applying the early declamping technique. The estimated blood loss was 200 mL. The serum creatinine right after the operation, on the first day, 3 days, and 90 days after surgery were 0.92, 0.77, 0.79, and 0.81 mg/dL, respectively. For 90 days after the procedure, no complications or radiologic recurrence were observed. Further clinical studies will reveal the advantages of using the DaVinci SP device for this procedure over traditional multiport surgery, maximizing the benefit of a single port-based approach.

  • We investigated the biochemical properties of insect defensin expressed and secreted from Saccharomyces corevisiae. The defensin showed extremely high resistance to boiling for up to 30 min and to pH values tested from 2.0 to 12.0. The treatment of defensin with various proteases abolished antibacterial activity. However, amylases, cellulase, lipase and catalase had no effect on the activity. The defensin was purified to homogeneity through ammonium sulfate concentration of culture supernatant, SP-Sepharose column chromatography and RP-HPLC. Tricin-SDS-PAGE analysis revealed that the molecular weight of the defensin was about 4.0 kDa. The antibacterial activity of the purified defensin was verified by renaturation of stained gel and gel pouring assay using Micrococcus luteus as a test organism.

  • Studies in adipocytes indicate that secretion of active lipoprotein lipase (LPL) was strictly regulated by a quality control system in the endoplasmic reticulum (ER). However, there has been no report about the ER chaperones participating in the folding and assembly of LPL. Many chaperones are known to bind unfolded proteins and dissociate from them through the ATP-hydrolyzing reaction. In this study, putative ER chaperones for LPL were determined by affinity chromatography using denatured LPL as an affinity ligand and elution with ATP. BiP, grp94, calreticulin, and another 50 kDa K-D-E-L protein in the ER of rat adipose tissue were bound to denatured LPL and eluted by ATP. Calnexin was bound to denatured LPL; however, it was not eluted by ATP but by acetic acid. These results indicate that, at least, BiP, grp94, calreticulin, calnexin, and the unidentified 50 kDa protein might act as putative chaperones for the proper folding and assembly of LPL in ER.
