Vascular leak syndrome(VLS) is characterized by endothelial damage, which causes extravasation of plasma proteins and fluid from capillaries into the extravascular space. It has been suggested that the increased vascular permeability is the result of an IL-2-induced suppression of endothelin-1 secretion by endothelial cells, an IL-2-induced activation of the complement cascade or TNF-alpha release from IL-2-activated T-cells. A 13-year-old male patient visited our hospital with abdominal pain. He was diagnosed with acute lymphoblastic leukemia(T cell type) by bone marrow study on his 2 nd day in hospital. On the 3 rd day of induction chemotherapy(prednisone, L-asparaginase, vincristine, intrathecal methotrexate), pulmonary edema and pleural effusion, ascites and generalized edema developed and lasted for 53 days without responding to supportive care. The laboratoy finding was that TNF-alpha was increased without evidence of infection and hypoalbuminemia was noted. It was suggested that the patient's clinical feature was induced by VLS.

We immunized sixty two healthy subjects with the five different viral titers (300, 500, 1000, 1500 and 2000 plaque forming unit; pfu) of the MAV/06 strain of live attenuated Varicella-zoster virus (VZV) in order to gain sufficient information on safety and immuogenicity as a vaccine strain. Humoral immunity of all vaccine recipients was tested by the fluorescent antibody to membrane antigen (FAMA) assay and Enzyme-linked immunosorbent assay (ELISA) for the quantitative detection of IgG antibody. We tested neutralized antibody in 62 subjects by plaque reduction neutralization test (PRNT50). All of thirty two subjects with initial seronegative response had antibody by FAMA method at four weeks after immunization with four different preparations of dosage. The geometric mean titers (GMTs) of VZV antibody to membrane antigen was 160.9 in 6 subjects with 1500 pfu group; 83.3 in 14 subjects with 1000 pfu group: 116.2 in 7 subjects with 500 pfu groups and 72.0 in 6 subjects with 300 pfu group. Thirty subjects who had VZV antibody at the time before immunization demonstrated elevated antibody titer by FAMA assay and PRNT50 test. Side reactions of the vaccination was not demonstrated in all cases.

BACKGROUND: Neuropathic pain produced by nerve injury has the characteristics of enhanced pain responses - allodynia. To understand the pathophysiology of the neuropathic pain, We evaluated the effect of NMDA antagonists and chemical sympathectomy on the c-fos mRNA expression. METHODS: We have divided rats(Sprague-Dawley, N=24) that their left L5 and L6 nerve were tightly ligated into two groups. In NMDA antagonist group(N=17), We injected 10 g MK801 and 10 g 5-amino-phosphonovalerate in three ways, intrathecally before the ligation, after ligation and subcutaneous continuously. Then behavioral tests for mechanical allodynia and cold allodynia were performed. After the test of allodynia,the expression of c-fos were assessed by Northern blot hybridization. In chemical sympathectomy group(N=7), We injected 70 mg/kg guanethidine into the peritoneum in two ways, before the ligation and after ligation. Then same methods were performed in NMDA antagonist group as well. RESULTS: Intrathecal NMDA antagonists before the ligation supressed the elevation of c-fos mRNA expression. Intrathecal NMDA antagonists on the 7 days after the ligation reduced the c-fos mRNA expression and neuropathic pain. Continuous treatment of subcutaneous NMDA antagonists supressed the development of neuropathic pain and the elevation of c-fos mRNA expression. Chemical sympathectomy before the ligation did not supress the elevation of c-fos mRNA expression. Chemical sympathectomy on the 7 days after the ligation reduced neuropathic pain and the elevation of c-fos mRNA expression. CONCLUSIONS: NMDA receptor is related to the induction and maitenance of neuropatic pain, and sympathetic nervous system has a main role in the already induced neuropathic pain.

Lichen myxedematosus(LM), also known as papular mucinosis, is a rare, idiopathic disorder caused by the focal dermal deposition of mucin and occurs both as an isolated entity and manifestations of various systemic disorders. Cutaneous disease is common in patients infected with human immunodeficiency virus(HIV) and cutaneous mucinosis has been reported with increased frequency in HIV patients. A male patient with HIV infection was consulted to our clinic for evaluation of asymptomatic diffusely-scattered papules on his upper extremities and trunk. Histopathological finding was the deposition of mucin in the dermis and lichen myxedematosus type 2 was diagnosed. We present of a case of lichen myxedematosus in a HIV-infected male patient.

Kidney cells of canine embryos were separated into single cells using collagenase and dispase. Primary culture was conducted using these cells. To remove fibroblasts, these cells were treated with edetate disodium dihydrate (Na2EDDA), and pure epithelial cells were separated. Recombinant retrovirus particles that manifest teromerase were produced and inoculated into primary culture cells to produce immortalized canine cell strains (JNUCK-1 and JNUCK-2). To examine the characteristics of the produced cell strains, the growth curve, maximum cultured households, and expressed proteins (keratin) were identified. The JNUCK-1 and JNUCK-2 cell lines showed division ability until the 30th generation without growth retardation. JNUCK-1 and JNUCK-2 cell lines clearly expressed telomerase until the 25th generation. The canine distemper virus (CDV) was inoculated into the JNUCK-1 and JNUCK-2 cell lines, as well as in the Madin-Darby canine kidney (MDCK) cell line. The maximum titer of CDV from the JNUCK-1 cell strain was about 200 times higher than that from the MDCK cell strain. However, the JNUCK-2 cell strain produced a lower titer than the MDCK cell strain. We established a new canine kidney epithelial cell line (JNUCK-1) that could produce CDV with high titer.
