Abstract
BACKGROUND Effective treatment for breast cancer-related chronic lymphedema (bcrl) remains a clinical challenge. Acupuncture and moxibustion treatments have been shown to be beneficial and safe for treating bcrl. In the present randomized controlled trial, we compared the effectiveness of combined acupuncture and moxibustion ("warm acupuncture") with that of diosmin in bcrl. METHODS Breast cancer patients who met the inclusion and exclusion criteria (n = 30) were randomized to experimental and control groups (15 per group). On alternate days, patients in the experimental group received 30 minutes of acupuncture at 6 acupoints, with 3 of the needles each being topped by a 3-cm moxa stick. The control treatment was diosmin 900 mg 3 times daily. The control and experimental treatments were administered for 30 days. Outcome measures included arm circumferences (index of effectiveness), range of motion [rom (shoulder joint function)], quality of life, clinical safety, and adverse events. RESULTS Measured by the index of effectiveness, bcrl improved by 51.46% in the experimental group and by 26.27% in the control group (p < 0.00001). Effects were greatest at 10 cm above the elbow and at the wrist, where the warm needling was provided. Impairments in shoulder joint rom were minimal at baseline in both treatment groups. However, the roms of rear protraction, abduction, intorsion, and extorsion in the experimental group improved significantly; they did not change in the control group. Self-reported quality of life was significantly better with warm acupuncture than with diosmin. No adverse effects were reported during the treatment period, and laboratory examinations for clinical safety fell within the normal ranges. CONCLUSIONS Compared with diosmin, warm acupuncture treatment can effectively reduce the degree of bcrl at the specific acupoints treated and can promote quality of life. Warm acupuncture showed good clinical safety, without any adverse effects on blood or the cardiovascular system.

Abstract
BACKGROUND Romidepsin, a histone deacetylase (HDAC) inhibitor, has been approved for the treatment of relapsed and refractory peripheral T-cell lymphoma. However, the efficacy and safety of romidepsin has never been studied in patients with relapsed or refractory extranodal natural killer (NK)/T-cell lymphoma (ENKTL). PATIENTS AND METHODS We conducted an open-label, prospective pilot study to evaluate the efficacy and feasibility of romidepsin in the treatment of patients with ENKTL. The treatment was intravenous infusion of romidepsin (14 mg/m(2)) for 4 h on days 1, 8, and 15 of a 28-day cycle, and was repeated until disease progression or the occurrence of unacceptable toxicity. RESULTS A total of five patients enrolled on to this pilot study. However, three patients developed fever and elevated liver enzyme and bilirubin levels immediately after their first administration of romidepsin. We suspected that these events were associated with Epstein-Barr virus (EBV) reactivation because of the rapidly elevated EBV DNA titers in blood from these patients. An in vitro study with the ENKTL cell line SNK-6 cells also showed that HDAC inhibitors including romidepsin increased the copy number of EBV DNA in a dose-dependent manner. These findings suggested that romidepsin-induced histone acetylation reversed the repressed state of the genes required for EBV reactivation and that romidepsin treatment may have caused EBV reactivation in EBV-infected tumor cells in ENKTL patients. Therefore, we discontinued the enrollment of patients into this pilot study. CONCLUSIONS Our study suggests that the use of romidepsin may cause severe EBV reactivation in patients with ENKTL.

Abstract
Disparity of minor histocompatibility antigens (mHAs) is known to induce graft-versus-tumor and graft-versus-host disease reactions in stem cell transplantation. Not much information is available on genotypic and phenotypic distributions of the currently identified mHAs, especially in Korean population. Therefore, we report genotype and phenotype frequency analyses of 10 autosomal mHAs in 329 unrelated healthy Koreans using the Sequenom MassARRAY matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry (MS) system and polymerase chain reaction-sequence specific primers (PCR-SSP). Estimates of the probability of immunogenic mismatches between donor/recipient pairs were made from observed phenotypic frequencies. HA-1 was the most favorable mHA for clinical application with the highest disparity of 7.0%. Similar results were obtained in ACC-1. The Korean population can benefit the most in a setting of matched major histocompatibility complex (MHC)-restricted mHAs-mismatched unrelated hematopoietic stem cell transplantations with the disparity rate of 27.5% with eight hematopoietic mHAs. This is the first comprehensive report on the genotypic and phenotypic frequency distributions of human mHAs in the Korean population. It can contribute to not only donor selection before transplantation but also therapeutic approaches after transplantation. It is expected that mHA-based immunotherapy will lead to a new treatment modality tailored for patients at high risk of relapse following allogeneic hematopoietic cell transplantation.

Abstract
A serological and genetic study of Korean blood donors with phenotypic group A subtypes was performed. There were 176 donors with phenotypic A subtypes identified. Exons 6 and 7 from 57 representative donors were sequenced. The A(var) allele (784 G > A) was cloned and sequenced, and a family study demonstrating its inheritance and unusual serological characteristics was performed. The A102 allele was the most frequently identified allele in phenotypically A2 (58%, 11/19) and A2B (68%, 17/25) donors. Anti-A1 was rarely present amongst A2 and A2B donors. The family study revealed that the A(var) allele was expressed as phenotype A(weak)B in A(var)/B heterozygote members, but as phenotype O in A(var)/O heterozygotes. The most frequent allele in Korean donors with the A2 phenotype differs from its Caucasian counterpart, as does the frequency of anti-A1. The A(var) allele demonstrates allelic enhancement in A(var)/B heterozygotes.

BACKGROUND AND OBJECTIVES Genetic analysis of group B donors in Korea was performed. MATERIALS AND METHODS Exons 6 and 7 were sequenced in 12 phenotypically B3 donors 6 B3, 6 A1B3. RESULTS Consensus sequences all B3 and 2/6 A1B3 donors were present. Four A1B3 donors demonstrated a novel B allele, B(var), in the context of A101/ or A102/B(var) genotypes. Family studies based on an A1B3 donor with the B(var) allele and on another unrelated subject with identical genotype and phenotype revealed B(var)/O01 genotypes with full B-antigen expression. CONCLUSIONS B(var) allele is subject to differential expression, depending on the co-inherited ABO allele.

Abstract
Alzheimer's disease (AD) is a multifactorial disorder with possible involvement of several genetic and environmental factors. For late-onset AD (LOAD), the epsilon4 allele of apolipoprotein E (APOE) has been identified as a major susceptible gene. However, the observation that APOE epsilon4 accounted for approximately one half of the genetic variance of LOAD prompted many researchers to undertake genome surveys to identify other susceptible genes. Recently, several candidate genes such as alpha-1 antichymotrypsin (ACT) and alpha-2 macroglobulin (A2M) were reported to be associated with LOAD. To evaluate the possible association between these genes and LOAD in Korean population, we genotyped ACT A/T and A2M 5-bp deletion (exon 18) polymorphisms in 89 LOAD cases and 50 age-matched healthy controls. The frequencies of ACT A and A2M 5-bp deletion alleles in LOAD and controls were 0.39 vs. 0.37, and 0.05 vs. 0.05, respectively. Although APOE epsilon4 clearly showed higher frequency in LOAD (0.34) than that in controls (0.09), giving an odds ratio of 5.14 (95% confidence interval, 2.31-11.76), neither ACT nor A2M showed statistically significant difference between LOAD and controls regardless of APOE carrier status. Our results do not support previously reported association of ACT and A2M with LOAD, at least in Korean population.

Abstract
We expressed a protein in Saccharomyces cerevisiae in order to evaluate the humoral immune responses to the C-terminal region of the merozoite surface protein 1 of Plasmodium vivax. This protein (Pv200(18)) had a molecular mass of 18 kDa and was reactive with the sera of individuals with patent vivax malaria on immunoblotting analysis. The levels of immunoglobulin M (IgM) and IgG antibodies against Pv200(18) were measured in 421 patients with vivax malaria (patient group), 528 healthy individuals from areas of nonendemicity (control group 1), and 470 healthy individuals from areas of endemicity (control group 2), using the indirect enzyme-linked immunosorbent assay (ELISA) method. To study the longevity of the antibodies, 20 subjects from the patient group were also tested for the antibody levels once a month for 1 year. When the cutoff values for seropositivity were determined as the mean + 3 x standard deviation of the antibody levels in control group 1, both IgG and IgM antibody levels were negative in 98.5% (465 of 472) of control group 2. The IgG and IgM antibodies were positive in 88.1% (371 of 421) and 94.5% (398 of 421) of the patient group, respectively. The IgM antibody became negative 2 to 4 months after the onset of symptoms, whereas the IgG antibody usually remained positive for more than 5 months. In conclusion, indirect ELISA using Pv200(18) expressed in S. cerevisiae may be a useful diagnostic method for vivax malaria.

Abstract
Butyrylcholinesterase (BChE) as well as acetylcholinesterase has been suggested to be associated with Alzheimer's disease (AD). Lehmann et al. [1997: Hum Mol Genet 6:1933-1936] recently reported the synergism between the gene for the K variant of BChE (BCHE-K) and the epsilon4 allele of apolipoprotein E (APOE epsilon4) in late-onset confirmed AD with Caucasian subjects. The authors found that the allelic frequency of BCHE-K was 0.17 in 74 subjects with late-onset histopathologically diagnosed AD, which was higher than the frequencies in elderly control subjects (0.09) and in other dementias (0.07-0.10). The association of BCHE-K with late-onset AD was limited to carriers of APOE epsilon4, giving odds ratios of confirmed late-onset AD of 6.9-12.8. In the present study, we report the BCHE-K allelic frequencies in late-onset AD cases and in age-matched controls of the Korean population, which were 0.22 and 0.17, respectively. We could not find any association between BCHE-K and AD regardless of APOE epsilon4 carrier status. However, APOE epsilon4 clearly showed higher frequency in AD (0.33) than in elderly controls (0.09), giving an odds ratio of 5.2 (95% confidence interval, 2.7-10.0). Our results do not support the conclusion that BCHE-K, or a nearby gene on chromosome 3, acts in synergy with APOE epsilon4 as a susceptibility gene for late-onset AD, at least in the Korean population.
