  • An Infectious hematopoietic necrosis virus strain (IHNV-RTK) was isolated from cultured rainbow trout at Kumi and Jechun area in Korea during 2000 and 2001. In the RT-PCR amplification with the specific primer set designed from IHNV G protein region, a 540 bp PCR product was amplified from the RTK strain. The RTK strain showed higher sequence homology with the published IHNV G protein genes (RB-76, LR-73, Col-85, and Carson-89)

  • Mariculture of rainbow trout Onchorhynchus mykiss has been initiated in or around olive flounder Paralichthys olivaceus farms, where viral hemorrhagic septicemia virus (VHSV) is often detected in some fish. In the present study, we investigated VHSV infection in seawater-reared rainbow trout because VHSV has never been detected in salmonids in Korea. A total of 104 adult fish were tested for the presence of VHSV by reverse transcription-polymerase chain reaction, followed by virus isolation with the fathead minnow caudal trunk cell line. Cytopathic effects were observed in two samples but the virus was identified as infectious hematopoietic necrosis virus. Thus, VHSV was not isolated from seawater-reared rainbow trout.

  • Biological response modifiers (BRMs) can alter interactions between the immune system and cancer cells to boost, direct, or restore the body's ability to fight disease. Mice with ethylnitrosourea- (ENU) induced leukemia were here used to monitor the therapeutic efficacy of lipopolysaccaride (LPS), Bacillus Calmette Guerin (BCG) and sheep erythrocytes (SRBC). Flow cytometry based CD34+ positivity analysis, clonogenicity, proliferation and ultrastructure studies using scanning electron microscopy (SEM) of stem cells in ENU induced animals with and without BRMs treatment were performed. BRMs improved the stem-stromal relationship structurally and functionally and might have potential for use as an adjunct in human stem cell therapy.

  • Several molecular biological techniques have been used to detect virus rapidly and accurately, but these methods have limitations in the early stage of viral infection with very low concentration of virus. We compared the detection limits of IMS-PCR, Western blot and ELISA with infectious hematopoietic necrosis virus OHNV). Four antibodies, rabbit anti-IHNV polyclonal antibody, anti-IHNV nucleocapsid protein monoclonal antibody, anti-IHNV nucleocapsid protein polyclonal antibody, and anti-IHNV glycoprotein polyclonal antibody, were tested to find out the most effective antibody for each method. The detection limit with IMS- PCR was $2\times10^6$ pfu when the viral RNA was extracted before RT-PCR. In the western blot with rabbit anti­IHNV polyclonal antibody one pfu of virus could be detected. In ELISA, 10 pfu of virus particles were detected with the same antibody.

  • Hematopoietic stem cells in bone marrow form all kinds of blood cells. In traditional medicine, functions of bone marrow cells are very similar to those of Essence(精) which is a fundamental factor of physical development and reproduction. Our experiment examined the effect of deer blood on aplastic anemia induced mouse using cyclophosphamide 150 mg/kg i.p injection before experiment and then another cyclophosphamide 120 mg/kg i.p injection on day 10. Then we administrated dried deer blood in distilled water for 5 days, 9 days and 10 days. We examined blood and marrow samples. In results, deer blood showed a trend of effectiveness on recovery of red blood cells and erythropoietin although they were not statistical significant. And deer blood did not show changes in CD34.

  • Pim kinases are promising targets in the treatment of hematopoietic and solid cancers. Meridianin C was chosen as a starting point to discover novel pim kinase inhibitors. Using known pim kinase's structural information, aminopyrimidine was introduced to provide the hydrogen-bonding interactions with the conserved lysine residue in the ATP binding pocket of all three Pim kinases. Synthesized 3,5-bis(aminopyrimidinyl)indole derivatives showed pan-pim inhibitory activity. Aminoalkyl substituent was attached on the aminopyrimidine to further enhance the potency and physicochemical properties of compound. The research reveals a significative way of designing compounds with high potency and kinase selectivity for pan-pim kinases.

  • Toluene is an aromatic hydrocarbon found in glues, cements, and solvents. It is known to be toxic to the nervous system, hematopoietic system, and causes acid-base and electrolyte disorders. Acute respiratory failure with hypokalemia and rhabdomyolysis with acute renal failure should be considered as potential events in protracted glue sniffing. We reported the case of 26-year-old woman was admitted to the emergency department with the development of respiratory failure and altered mentality due to hypokalemia after chronic glue sniffing. She was weaned from the ventilator 3 days later after potassium and sodium bicarbonate replacement and was discharged without respiratory symptoms and other complications.

  • In Malaysia, diagnosis and treatment of patients with mucopolysaccharidoses (MPS) is mainly localized at Hospital Kuala Lumpur, which is the national referral center for rare diseases. To date there are 83 patients diagnosed with MPS in our center, with MPS II being the commonest. The Malaysian National Medicines Policy second edition has a specific section on the orphan drugs which includes recombinant human enzyme for enzyme replacement therapy (ERT) in MPS. So far, National Pharmaceutical Regulatory Agency Malaysia has approved recombinant human enzyme for MPS types I (Loranidase), II (idursulfase), IVA (elosulfase alfa), and VI (Galsufase). Access to Idursulfase beta (another recombinant human enzyme for MPS II) and vestronidase alfa-vjbk (MPS VII) required special authorization on named patient basic. Currently there are 25 patients receiving ERT, 70% of the funding are from Ministry of Health (MOH), the remaining 30% are from various charitable funds and humanitarian programs. Thirteen newly diagnosed patients have to queue for an additional fund. Four patients have been treated with Hematopoietic stem cell transplant. MOH has also published guidelines regarding the patient selection criteria for ERT and treatment monitoring schedule.

  • Cord blood (CB) has been used as an important and ethical source for hematopoietic stem cell transplantation (SCT) as well as cell therapy by manufacturing mesenchymal stem cell, induced pleuripotential stem cell or just isolating mononuclear cell from CB. Recently, the application of cell-based therapy using CB has expanded its clinical utility, particularly, by using autologous CB in children with refractory diseases. For these purposes, CB has been stored worldwide since mid-1990. In this review, I would like to briefly present the historical development of clinical uses of CB in the fields of SCT and cell therapy, particularly to review the experiences in Korea. Furthermore, I would touch the recent banking status of CB.
