  • Dissolution and degradation of the parasporal crystal proteins produced from B. thuringiensis var. kurstaki, B. thuringiensis var. dendrolimus and B. thuringiensis var. aizawai were investigated. SDS-polyacrylamide gel electrophoresis analysis showed that the crystals contained major protein with molecular weight of approximately 134 kDa for B. thuringiensis var. aizawai 143 kDa for B. thuringiensis var. kurstaki and 149 kDa for B. thuringiensis var. dendrolimus, respectively. Crystals of three other strains were incubated alkali solutions at various pH or gut juice of Silkwarm Bombyx mori, Fall webworm Hyphantria cunea, and Common Cabbage worm Pieris rapae. When crystals of these strains were solubilized by alkali solutions, no major differences among strains B. thuringiensis could be detected. Among the strains studied, crystal protins (130-66 kDa) consist of protease resistant polypeptides in the 45-66 kDa size range when treated with gut juice of three insect species.

  • In this case, a 39 year-old man was admitted with Budd-Chiari syndrome associated with complete superior vena cava(SVC) obstruction causing general edema and hepatic failure. Conservative medical therapy was failed. And after the radiologist failed to invasive procedure of balloon dilatation, we attempted the inferior vena cava to right atrium bypass graft. Operation was done through median sternotomy and extended vertical oblique abdominal incision. A 24 mm Dacron tube was placed from the inferior vena cava just below the left renal vein to the right atrium without using the cardiopulmonary bypass pump. The patient's postoperative course was uneventful without signs of bleeding or any other complications. We used anticoagulants at the postoperative first day. At the postoperative 26th day, we performed abdominal Doppler sonography and we confirmed that the graft patency was good. The patient was discharged with SVC obstructive symptoms but we noticed relief of SVC obstructive symptoms in the course of follow-up.

  • In our previous report (Korean J. Food Sci. and Technol., 9, 123, 1977) we have studied the functional properties of soy protein isolates prepared from defatted soybean meal. For the practical application of the data described, beef patties substituted with SPI, and imitatied ice cream were prepared and sensory evaluations were carried out. The sensory analyses indicated that the beef patties substituted with gelated SPI to 30% have no detectable difference to the control at the significant level of 0.01. The imitation of ice cream whose milk-solid-not-fat was substituted with soy protein isolates showed the same texture as the control. Flavor of ice cream, however, has significant difference to the control due to beany-off flavor. Therefore removal of beany-off flavor is required for the substitution in ice cream.

  • This experimental research is aimed to apply a health promotion program based on Cox's interaction model to such college students as are on the brink of dyslipidemia, so as to investigate the effects of the program on the subjects' blood lipid indexes including total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL), and low-density lipoproteins (LDL). The subjects are 39 in all including the experimental group comprising 20 and the control group comprising 19. The analyses applied include descriptive statistics using SPSS WIN 18.0, $X^2$-test, independent t-test, and paired t-test. By means of nursing interventions which are an element of client-professional interaction, the following were offered including health information (exercise management, dietary management, health education), emotional support (sharing of experiences, encouragement, self expression), decision-making controlling (counselling by phone), and professional/ technical abilities; and blood lipid indexes were measured before and after the interventions. The results of this research found that TC, TG and LDL decreased significantly and HDL increased significantly in the experimental group, which indicates that the health promotion program was effective.

  • 모체의 당뇨병은 신생아 호흡부전 증후군의 중요한 소인의 하나이며, 이것은 태아의 폐성숙이 지연되어 폐포를 안정화시키는 표면활성물질의 결여에 기인하는 것으로 알려져 있다. 폐의 표면활성물질은 지질과 소량의 단백으로 이루어진 복합물질로서 그 주성분은 phosphatidyl choline이며 동물의 종속에 관계없이 임신 말기에 그 양이 현저히 증가한다. 양수내 인지질은 주로 태아 폐에서 유래하므로 임신 말기의 양수내 lecithin/sphingomyelin(L/S)비 측정으로 태아의 호흡부전 증후군을 예측할 수 있다. 일반적으로 당뇨병 모체의 양수는 L/S비가 낮아 당뇨병 산모로 부터 출생한 신생아에서 호흡부전증의 발생빈도가 높으므로 이를 예방하기 위하여 부신피질호르몬의 투여가 고려되고 있다.

  • The adherence of $^{3}H$-labeled oral streptococcal cells to protein-coated hydroxyapatite (HA) beads was studied by a standard adherence assay. The adherence equilibrium for S. mutans 10449 occured in about 2 hrs. The cell numbers adhering to SHA was 50% less than those on bare HA. Sailva from different subjects had varying effect on bacterial adherence. The use of saliva adsorbed with homologouis bacteria decreased S. mutans adherence by 38% ; this indicates the presence of salivary agglutinin in acquired pellicle formed on HA. Animal sera and BSA decreased S. sanguis adherence. BSA concentration as high as 10mg/ml caused up to 87% adherence inhibition. The desorption experiment of adhered bacteria confirmed the previous reports that the adhesive sites on HA beads for S. mutans were different from those for S. sanguis and that S. mutans could enhance the adherence of S. sanguis but not vice versa.

Hematological values and plasma protein of 94 boys and 91 girls (total 185 students)were studied. As the results of this survey, the following conclusions were obtained. 1. Hemoglobin, hematocrit, mean corpuscular hemoglobin concentration of boys and girls were increased after school lunch. 2. Plasma protein of boys and girls were clearly increased after school lunch.

  • Purpose : Respiratory syncytial virus(RSV) is the major cause of lower respiratory tract infection in infants and young children. This study was performed to analyze antigenic and genetic variation of G protein of subgroup A RSV. Methods : One hundred seventy-nine strains isolated at the Seoul National University Children's Hospital over 8 years-period from 1990 through 1998 were analysed for antigenic and genetic variability. Analysis was made by reactivity with monoclonal antibodies raised against RSV, and by restriction mapping and, for selected strains, nucleotide sequencing following amplification of full sequence of G gene by reverse transcription-polymerase chain reaction. Results : Restriction fragment analysis of the amplified G protein gene revealed 23 restriction patterns, 12 of which included more than 2 isolate, and the most frequent genetic type comprised 30% of the strains. Indirect immunofluorescent staining with monoclonal antibodies revealed 6 antigenic types with one predominant pattern accounting for 91% of the total strains. The most frequent antigenic type had 21 restriction patterns, and some viruses with same restiction pattern had different monoclonal antibody reaction pattern. Nucleotide sequence homology of subgroup A was 91~93% between reference(A2, Long) and Korean isolates, 93~99% among Korean isolates. Maximum-parsimony analysis demonstrated that Korean isolates were distinct from reference strains and subgroup A strains were clustered in 4 groups. Conclusion : The restriction analysis pattern of G protein gene identified greater diversity within subgroup A than was seen with the monoclonal analysis and a variety of antigenic and genetic types of RSV are circulating in Korea which are different from reference strains or strains isolated from other countries.
