Fluconazole의 진균 감염증 예방 효과와 안전성에 관하여 3개 대학병원에서 관해유도화학요법을 받는 급성 백혈병환자를 대상으로 무작위 배정법과 너도나도 누가림법에 의하여 연구하였다. 모두 62명의 환자에게 fluconazole(100㎎ bid) 또는 nystatin(1,000,000IU/day)을 무작위로 투여하였다. 투약은 관해유도화학요법과 같은 날짜에 시작하여 호중구수가 1,000㎣이상으로 회복되거나 진균 감염증이 확인되거나 의심되어 Amphotericin-B를 시작하거나, 약과 관련된 부작용이 나타날 때까지 계속하였다. 진균 colonization은 fluconazole군에서 감소하였으나 nystqatin군에서는 증가하였다, 표재성 진균감염증으로 nystatin군에서 C. albicans 진균혈증 1례와 C.parasilosis 진균혈중 1례가 발생하였다. 경험적 항진균요법으로 Amphotericin-B를 투여한 경우는 fluconazolerns 34명중 7례(21%), nystatinrns 28명중 10례(36%)였다(p<0.05). Fluconazole군과 nystatin군 사이에 부작용이나 사망률에 차이는 없었다. 결론적으로, fluconazole은 관해유도화학요법을 받는 급성 백혈병환자에서 진균의 colonization을 줄이는데 효과적이고 안전한 항진균제이다. We made a randomized, double-blind, multicenter trial to compare the efficacy and safety of fluconazole with nystatin for prevention of fungal infections in patients with acute leukemia. Sixty-two adult undergoing remission induction chemotherapy for cute leukemia were enrolled. Patients were randomly assigned to receive either fluconazole (100㎎ bid) or nystatin(1,000,000IU×6/day) with corresponding placebo. The study drug was started in initiation of chemotherapy and continued until recovery of neutrophil counts(>1,000/㎣), development of proven or suspected invasive fungal infection, or the occurrence of drug-related toxicity. Fungal colonization decreased in fluconazole(F) group, however increased in nystain(n) group. Superficial fungal infection occurred in 1 of 34 F group, whereas invasive fungal infection developed in 3 of 28 N group. Empirical amphotericin-B therapy was given in 7 of 34(21%) F group and 10 of 28(36%) N group(p>0.05). The incidence of drug-related side effects and overall moratlity were similar in both study groups.

The clinical value of empiric therapy of amphotericin B in 19 patients who were still febrile and granulocytopenic despite coverage of broad-spectrum antibiotics for 6 days was investigated. The clinical response rate was 52.6% on NCI criteria and 21% on EORTC criteria. The mortality rate was 36.8%.

Schwann cells(SCs), an important component of the peripheral nervous system, intract with nerous to mutually support growth and replication for the peripheral nerve regentation. Recently, ading SCs to the lumen of guidance channel is widely tried to improve regeneration or to make regeneration possible over otherwise irreparable gaps. however, it is not easy to isolate and multiplicate SCs as much as enough to help the axonal regeneration. For the allogeneic SCs source for tubular nerve guidance, we developed a little bit improved technique of harvesting and multiplicating SCs. by culturing dispersed dorsal root ganglia in specially designed medium with growth factors and serial processing, we repeatedlly generate relatively homogenous SC cultures. Our technique was compared with other methods of literature using immunostaining methods such as GFAP, S100, BDNF and the total SC count assessment at different time interval after primary culture.

The third generation cephalosporin is widely used in treatment of spontaneous bacterial peritonitis (SBP). Resistance to the third generation cephalosporin was associated with poor outcome in patients with SBP. Thus it is necessary to know the changes in resistance rate. We planned to investigate retrospectively on resistance rate of the third generation cephalosporin of gram negative bacteria isolated in patients with SBP, who visited Seoul National University Hospital between 1998 and 2006. The Clinical and Laboratory Standards Institute guidelines were applied for antibiotic susceptibility test. A total of 269 consecutive episodes of clinically and microbiologically proven SBP was identified during the study period and 209 cases were caused by gram negative organisms. Among 209 isolates, 22 (10.5%) showed resistance to the third generation cephalosporin. The prevalence of resistance was decreasing during the study period (P=0.014).

Backgroud : Drug resistant virus has been seen with all effective antiretroviral drugs in current practice. The isolation of resistant virus from subjects is associated with more rapid clinical outcome. The presence of resistance-conferring mutations in a patient in whom therapy is foiling indicates that other antiretroviral drugs should be considered. So, the identification of drug resistant Human Immunodeficiency Virus (HIV-1) mutations is of increasing importance. Zidovudine monotherapy for HIV-1 infection has been widely used in Korea since 1990. So, the prevalence of zidovudine resistant virus has been expected to be high. The purpose of the present study is to determine the prevalence of zidovudine resistant HIV-1 among zidovudine-naive Korean patients. Methods : We tested drug susceptibility of HIV-1 isolated from 19 zidovudine-naive Korean patients. We amplified a portion of gene reverse transcriptase of HIV-1 by RT nested PCR method. The susceptibility of HIV-1 to zidovudine was determined by sequencing the DNA base pairs of gene reverse transciptase. Results : Two (10.5%) of 19 HIV-1 isolates from zidovudine naive patients showed resistance conferring mutations to zidovudine. Two (2.1%) of 95 codons analysed from zidovudine naive patients showed mutations conferring resistance to zidovudine. Conclusion : The prevalence of zidovudine resistant HIV-1 was 10.5% among zidovudine-naive Korean patients. (Korean J Infect Dis 33:40~45, 2001)

The oriental tobacco budworm, Helicoverpa assulta, is an oligophagous insect feeding on a few species of Solanaceae plants, including Nicotina tabacum. This study investigated the relationship between H. assulta and plants, focusing on oviposition preference and larval performance of the specialist in host and non-host plants. (1) In choice experiments, N. tabacum and Phaseolus vulgaris were put in a cage with 5 females and 10 males. Most of eggs (ca. 98%) were layed in N. tabacum, whereas few eggs in P. vulgaris. (2) In non-choice experiments, N. tabacum, Datura stramonium, or P. vulgaris was individually put in a cage with 3 females and 6 males, resulting that N. tabacum was the most preferred host, followed by D. stramonium and P. vulgaris. Oviposition was delayed about 2 days in P. vulgaris (a non-host plant) compared to the two host plants. (3) Larval performances were also compared with the three plants. Larval growth was better in N. tabacum followed by D. stramonium and P. vulgaris, High mortality (ca. 100%) of larvae was observed in P. vulgaris, suggesting toxic component(s) derived from the non-host plant might cause the death. The ovipositional avoidance in P. vulgaris is current being investigated to search for the oviposition deterrent, which could be useful for the environment-friendly pest management of H. assulta.

Rapamycin, a macrocyclic lactone, is effective in reducing the incidence of acute rejection after renal transplantation. The inhibitory effects of rapamycin on lymphocyte proliferation and the molecular mechanisms that were involved have been described. However, its effects on glomerular mesangial cells have not been clearly understood, and here, we examined the effect of rapamycin on platelet-derived growth factor (PDGF)induced extracellular matrix synthesis as well as cell proliferation in mesangial cells. Rat mesangial cells were isolated from the glomeruli of Sprague-Dawley rats and cultured with Dulbecco's modified Eagles medium containing 20% fetal bovine serum. Different concentrations of rapamycin were administered 1 hour before the addition of 10ng/ml of PDGF into growth arrested and synchronized cells. Cell proliferation was assessed by [³H]thymidine incorporation, total collagen synthesis by [³H]proline incorporation, and fibronectin secretion into the medium by Western blot analysis. In the mesangial cells, PDGF increased cell proliferation by 4.6-fold, total collagen synthesis by 1.8-fold, and fibronectin secretion by 3.2-fold. Rapamycin above 10 nM significantly inhibited PDGF-induced proliferation and collagen synthesis, but the treatment of rapamycin up to 1μM did not show any significant effects on PDGF-induced fibronectin secretion. These inhibitory effects of rapamycin on PDGF-induced mesangial cell proliferation and collagen synthesis reflect the potential value of rapamycin in the prevention and treatment of glomerulosclerosis in patients with chronic allograft nephropathy.
