Objective:To investigate the feasibility of clinical application of HLA-DRB,DPB1 genotyping by PCR-SSP,RFLP for alloge-neic bone marrow transplantation(Allo-BMT) .Methods: Corresponding to each of the DRB alleles, nineteen different pairs of sequence specific primers were used to PCR amplify them from twenty samples in both recipients and donors and their amplified products were directly analyzed on agarose gel. At the same time, a pair of primer was used to PCR amplify the second exon of DPB1 and the restriction fragment length polymorphisms were analyzed on PAGE after their PCR products were separately digested by ten endonucleases. Results: Each DRB was typed in according to its clear and visualized electrophoresis band; the DPB1 genotype was also determined by analysis of all codes representing polymorphism fragment band with a computer. Four couples of recipient and donor were matched. Conclusion:PCR-SSP and RFLP are rapid, accurate and reliable genotyping approaches for Allo-BMT.

Journal of Clinical Neurology 2005;1(2):107-120
Despite successful treatment of Parkinson's disease (PD) with a wide variety of symptomatic therapy, the disease continues to progress and drug-resistance symptoms become the predominant factors producing the disability of PD patients. Neuroprotective therapies have been tested, but clinically effective drugs have not been found yet. New insights gained from studies of genetic forms of PD point to the common pathogenic mechanisms that have been suspected in sporadic forms of the disease and may provide new approaches for the future neuroprotective therapies.

Objective To evaluate the clinical significance of sentinel lymph nodes biopsy (SLNB) in breast cancer patients after neoadjuvant chemotherapy. Methods SLNB was performed in sixty primary breast cancer patients after neoadjuvant chemotherapy using a combination of 99mTc- Rituximab and patent blue. SLN was examined by routine pathologic examination and immunohistochemistry. Routine axillary lymph node resection was performed after SLNB. Results The successful rate of SLNB was 95% (57/60). Twenty-three cases of SLN (40% ) were metastasis positive, including 18 positive cases detected by HE staining and 5 by immunohistochemistry. SLN was the only metastasis lymph nodes in 14 out of 23 cases. One case was of false negative metastasis by SLN. The sensitivity and accuracy of SLNB were 96% (23/24) and 98% (56/57), respectively. The specificity was 100% (33/33) , the false negative rate was 4. 3% (1/23) with the negative predictive value being 97% (36/37). The positive predictive value was 100% (24/24). Internal mammary sentinel lymph node lymphoscintigraphy were positive in 11 cases but all the cases were negative in metastases by pathologic examination. Conclusion The combination of isotope imaging agent and patent blue is suitable for primary breast carcinoma after neoadjuvant chemotherapy. Internal mammary sentinel lymph node biopsy is less clinically important.

BACKGROUND: Hepatitis B Virus (HBV) is a major risk factor for hepatocellular carcinoma, and about five to six percents of people are infected with HBV in Korea. Lamivudine is a first-line drug having good control against HBV replication, but long-term treatment by lamivudine induces drug resistance. We analyzed the rate of HBV resistance mutation for lamivudine by direct sequencing and CLIP sequencing. METHODS: HBV DNA was isolated from 371 patients who were in treatment, or were planning to be treated with lamivudine. The direct sequencing for lamivudine resistance mutation was performed in 371 patients and CLIP sequencing in 138 patients. We analyzed the mutation rate and the type of mutations for lamivudine resistance. RESULTS: The mutation was detected in 203 patients (54.7%) and (CTG) L180M (ATG) was most common (36.1%) followed by (ATG) M204I (ATT) (29.9%) and (ATG) M204V (GTG) (18.6%). According to the duration of treatment, mutation rates were as follows: 45.3% for less than one year, 71.7% for one to two years, 66.7% for two to three years, and 87.9% for more than three years. The results of the direct sequencing and CLIP sequencing agreed in 134 out of 138 patients, in whom both tests were performed. CONCLUSIONS: We confirmed that HBV mutation rates for lamivudine resistance increased as the lamivudine treatment period increased. The lamivudine resistance mutations detected were similar to the previous studies. CLIP sequencing showed good correlation with the direct sequencing and gave additional mutation information. CLIP sequencing is a promising tool for the detection of lamivudine resistance mutation in HBV that can assist treatment plans.

Ael is a rare blood type which has the least amount of A antigen among A subgroups. It can be detected by special tests performed to resolve the discrepancy between red cell and serum typing in routine serological typing. The presence of A antigen on Ael red cell is demonstrable only by adsorption and elution tests. An Ael individual does not secret A substance in the saliva and may have anti-A antibody in the serum which is usually less reactive with the reagent red cells than anti-B antibody. In Korea, Ael02 has been reported more frequently than other Ael alleles. We report a case of Ael02/O04 who presented as typical phenotype O with strong anti-A and anti-B antibodies and no A antigen detected even by adsorption and elution tests. The case has been proved to be Ael02/O04 by direct sequencing analysis. In individuals with history of discrepancies in the results of ABO phenotyping, ABO genotyping is needed for an accurate evaluation of their blood type.

OBJECTIVE: To compare the usefulness of prenatal screening tests for chromosomal abnormalities by analyzing the cytogenetic results of midtrimester amniocentesis METHODS: We reviewed a total of 1264 cases of midtrimester prenatal genetic amniocentesis performed from February 1997 to September 2003, of which accorded to indications of cytogenetic studies. Cytogenetic results were analyzed with the distribution of maternal age, indications of amniocentesis. RESULTS: The most common age of total subjects was in between 35-39 years (37.1%). The indications of amniocentesis were abnormal maternal serum marker (60.0%), advanced maternal age (34.8%), abnormal ultrasonographic findings (3.2%), in order. The overall incidence of chromosomal aberration was 3.9% (49/1264). No significant difference was found between the mean maternal age with and without abnormal fetal karyotype. According to indications, there was 12.5% (5/49) of chromosomal abnormalities in abnormal sonographic finding group, 5.2% (36/688) in abnormal maternal serum screening group and 2.4% (12/498) in advanced maternal age group. There was statistical significance (P=0.004) only in abnormal ultrasonographic finding group. CONCLUSION: Ultrasonography was become to be more important due to development of high resolution ultrasonography, skillful technique and awareness of sonographic markers. Ultrasonographic abnormality could be the most predictive marker for abnormal fetal karyotypes.
