  • The hyphal tip laccase of Coprinus congregatus which is a membrane-associated enzyme and shows diffdrdnt banding patterns of PAGE analysis when compared with the enzyme of liquid culture (Choi et al. 1987) has been successfully secreted to culture medium in liquid shake culture by lowering the pH of medium to 4.0. When the fungus is cultivated in YpSs(pH 4.0) liquid, only the hyphal tip laccase is found in the medium after 6 hr incubation and there is no liquid-type enzyme when examined by PAGE analysis.

  • This paper describes performance of sealing integrity and bending strain of HV polymeric bushing with thermal mechanical test. Generally the properties of FRP tube can be influenced by the winding angle, wall thickness and winding tension. As a results, multi winding bushing shows that it has max deflection in the range of 16.5~16.9 mm.

  • The Fontan operation for tricuspid atresia was first performed in 1968[Fontan and Baudet 1971] and several technical modifications of procedure were developed. We have experienced a case of modified Fontan operation for tricuspid atresia type Ic who was 5 years old female. She had previous palliative procedure \ulcornerpulmonary artery banding due to excessively increased pulmonary blood flow. The modified Fontan operation was right atrium to right ventricle connection with valve-bearing conduit. The result was good and the patient was discharged 20 days after operation.

  • Between 1981 and 1987, five patients with an interruption of the aortic arch were operated upon. All had a ventricular septal defect and a patent ductus arteriosus as associated anomalies. A two-stage procedure was employed in these cases, the initial procedure being repair of the interrupted arch, ligation of the patent ductus arteriosus, banding of the main pulmonary artery and a lung biopsy which was followed, 5 to 49 months later, by the repair of the ventricular septal defect. Four patients completed the two-stage procedure with one postoperative mortality. The remaining patient is yet to complete the second stage procedure.

  • This study investigates the improvement of domestic compression stockings by comparing and analyzing the characteristics of materials and fabrics of medical compression stockings developed in Korea and domestic imported compression stockings. Among imported compression stockings currently available in Korea, three brands with high sales rates are selected by countries (USA, Italy, and Germany) to measure the physical and mechanical properties of the material. Medical compression stockings to be analyzed were selected as M size pantyhose included in 20-30mmHg. As a result, the tensile elongation of medical compression stockings selected in this study was the highest in Korean products in the ankle, while the highest in the US was in the thigh, and the elasticity of Italian products was low. The recovery rate of the kidneys was similar for all four ankles. The ankle weight was the highest except for Korean products that showed the highest weight of the thigh and difference from products of other countries. US product also showed high shape stability due to high recovery of tensile strength from high value RT. Italian products showed low banding and shear values; however, shape stability was poor with good drapeability. In Germany, LT and RT values were low, but clothing comfort was considered excellent. In Korea, LT and RT values, banding and shear characteristics were high, and drapeability was poor. Stiffness was good, but recoverability was excellent.

  • Analysis of siR isolates of Trichemenes veginalis was carried out with sodium dodecyl sulfate- polyacrylamide gel electrophoresis (SDS-PAGE) and enzyme-linked immunoelectrotransfer blot (EITB). Trichloroacetic acid-treated antigens of the 6 isolates revealed 25 protein profiles ranging 12~170 kDa of molecular weight in SDS-PAGE. In EITB, the specific immunogenic bands were visualized at 51 kDa and 96 kDa when HY-1 antigen was probed with difFerent mice sera immunized with 6 isolates of T. vaginalis. The banding patterns with different sera showed isolate-to-isolate variability. In EITB, homologous antigen (HY-1) did not show any enhanced response in reacting to homologous antiserum(HY-1) when 6 isolates of T. vaginalis were probed with a single serum (HY-1). It is assumed that the different banding patterns of six isolates show isolate-to-isolate variability and immunogenic common bands in 41, 47, 74 and 9:k kDa on EITB may connote the important significance on immune response in T. vaginalis infection.

  • Hypoplastic left heart complex (HLHC) consists of less severe underdevelopment of the left ventricle without intrinsic left valvular stenosis, i.e., a subset of hypoplastic left heart syndrome (HLHS). HLHC patients may be able to undergo biventricular repair, while HLHS requires single ventricle palliation (or transplant). However, there is no consensus regarding the likelihood of favorable outcomes in neonates with HLHC selected to undergo this surgical approach. This case report describes a neonate with HLHC, co-arctation of the aorta (CoA), and patent ductus arteriosus (PDA) who was initially palliated using bilateral pulmonary artery banding due to unstable ductus-dependent circulation. A postoperative echocardiogram showed newly appearing CoA and progressively narrowing PDA, which resulted in the need for biventricular repair 21 days following the palliation surgery. The patient was discharged on postoperative day 13 without complications and is doing clinically well seven months after surgery.

  • Background: The difference in prognosis of adult and childhood acute lymphoblastic leukemia (ALL) can be attributed largely to variation in cytogenetic abnormalities with age groups. Cytogenetic analysis in acute leukemia is now routinely used to assist patient management, particularly in terms of diagnosis, disease monitoring, prognosis and risk stratification. Knowing about cytogenetic profile at the time of diagnosis is important in order to take critical decisions in management of the patients. Aim and Objectives: To determine the frequency of cytogenetic abnormalities in Pakistani adult patients with ALL in order to have insights regarding behavior of the disease. Materials and Methods: A retrospective analysis of all the cases of ALL (${\geq}15$years old) diagnosed at Aga Khan University from January 2006 to June 2014 was performed. Phenotype (B/T lineage) was confirmed in all cases by flow cytometry. Cytogenetic analysis was made for all cases using the trypsin-Giemsa banding technique. Karyotypes were interpreted using the International System for Human Cytogenetic Nomenclature (ISCN) criteria. Results: A total of 166 patients were diagnosed as ALL during the study period, of which 151 samples successfully yielded metaphase chromosomes. The male to female ratio was 3.4:1. The majority (n=120, 72.3%) had a B-cell phenotype. A normal karyotype was present in 51% (n=77) of the cases whereas 49% (n=74) had an abnormal karyotype. Of the abnormal cases, 10% showed Philadelphia chromosome; t(9;22)(q34;q11.2). Other poor prognostic cytogenetic subgroups were t(4;11)(q21;q23), hypodiploidy (35-45 chromosomes) and complex karyotype. Hyperdiploidy (47-57 chromosomes) occurred in 6.6%; all of whom were younger than 30 years. Conclusions: This study showed a relatively low prevalence of Philadelphia chromosome in Pakistani adults with ALL with an increase in frequency with age (p=0.003). The cumulative prevalence of Philadelphianegative poor cytogenetic aberrations in different age groups was not significant (p=0.6).
