BACKGROUND: Estrogen deficiency accelerates loss of bone mass and changes lipid profile in the postmenopausal women, so that the osteoporosis and astherosclerosis were developed. But it has not enough studies including the premenopausal women. So we have investigated about the differences of body mass index(BMI), lipid profile and bone mineral density (BMD) with pre- and postmenopausal women. METHODS: We have evaluated 201 premenopausal women and 322 postmenopausal women out of total 651 who had visited Health Screening Center in the hospital of Eul-Ji Medical College from November, 1995 to July, 1996. RESULTS: The mean age of total subjects, premenopausal women, postmenopausal women were 51.9, 43.9, 56.8 years, respectively. The mean period after menopause was 8.1 years. Significant difference was seen in BMI, lipid profile and BMD according to age and menopause(P<0.01). BMI was related to lipid profile(P<0.01), but not to BMD(P>0.1). In postmenopausal women BMI, BMD and lipid profile were related to postmenopausal period (P<0.05). In viewing their correlations BMD had strong adverse correlations with factors such as age, menopause, and postmenopausal period. Lipid profile had weak positive correlations with factors such as age, menopause, BMI(P<0.001). CONCLUSIONS: The lipid profile are related to factors such as age, BMI, menopause, and postmenopausal period. The BMD is related to above factors except BMI. Prospective study is needed to evaluate the influence of estrogen on BMD and lipid metabolism. Thus, it helps to the prevention and treatment of the osteoporosis and hyperlipidemia in the postmenopausal women.

BACKGROUND: Recent DNA polymorphism analysis using numerous DNA markers has been used to determine the parental origin of the extra chromosome 21 in Down syndrome. In this study we used seven dinucleotide repeat polymorphisms on chromosome 21 to characterize a case of rea(21q21q) and to know whether it is consistent with an isochromosome or a true Robertsonian translocation. METHODS: Cytogenetic investigation was done by conventional G banding DNA was extracted from whole blood of a proband and her parents and was amplified by PCR using seven sets of (GT)n repeat dinucleotide markers located on the long arm of chromosome 21 After electrophoresis of the PCR product in polyacrylamide gel and silver staining the parental origin and number of DNA copy were determined by visual comparison of the band intensities within and between individuals. RESULTS: Conventional cytogenetics showed that the proband had a 46.XX.re(21q21q) chromosome pattern. Parental chromosome studies were normal, therefore, the rearrangement was a de novo event. All seven DNA markers showed one or two alleles, demonstrating rea(21q21q) to be an isochromosome. For D21S215 and D21S156 markers both parents were heterozygous and the proband inherited one copy of paternal allele and two copies of maternal allele which both parents did not share. This finding was consistent with a maternally derided isochromosome. CONCLUSION: Use of dinucleotide repeat DNA polymorphisms after PCR amplification will be very useful to detect the parental origin of additional chromosome 21 or rearrangement of chromosome 21 in Down syndrome. Besides employing siltier staining of a PCR product we will be able to avoid using of radioisotopes and apply to clinical laboratory diagnosis.

Partial trisomy of the long arm of chromosome 5 distal to 5q33 is rare. Only 16 cases have so far been reported. We report on a three-year-old boy with microcephaly, growth and developmental delay, mild mental retardation, and facial dysmorphism caused by partial 5q trisomy and partial 7p monosomy. The patient has an apparently unbalanced translocation resulting from a rearrangement between chromosomes 5 and 7 (46,XY,der (7)t (5;7) (q33;p22)de novo). Fluorescence in situ hybridization with chromosome 5 and 7 painting probes and a cri-du-chat critical region probe confirmed this chromosome rearrangement. Most cases of partial trisomy 5q33-q35 described to date are due to the unbalanced transmission of a familial translocation. To the best of our knowledge, there are no previous reports of de novo unbalanced translocations of these two chromosome abnormalities together with similar breakpoints.

Background: The diagnosis of acute leukemia is multidisciplinary with histology, immunology, and cytogenetics. Among these, cytogenetics is important for diagnosis and analysis of prognosis and some of the chromosomal abnormalities are specific for the particular subtypes of acute leukemia. However, cytogenetic analysis is laborious and sometimes does not provide sufficient metaphases. To detect the common 7 gene rearrangements in acute leukemia, a reverse transcription-polymerase chain reaction (RT-PCR) was performed simultaneously under the same conditions. Methods: The author analyzed 38 cases of acute myeloid leukemia (AML) and 20 cases of acute lymphocytic leukemia (ALL) for the evaluation and treatment of acute leukemia. The simultaneous RT-PCR assays were performed under the same conditions to detect 7 chromosomal abnormalities of t(1:19), t(8; 21), t(9; 22), dupMLL (11q23), t(12; 21), t(15; 17), and inv(16) in acute leukemia. Results: The simultaneous RT-PCR assay detected the expression of 7 fusion genes generated by chromosomal rearrangement. The gene rearrangements were found in 53% of AML and 40% of ALL. In AML, there were 7 cases of PML/RARA, 6 cases of AML1/ETO, 4 cases of dupMLL, and 3 cases of CBF/MYH11. In ALL, 4 cases of dupMLL, 2 cases of BCR/ABL, 1 case of E2A/PBX1, and 1 case of TEL/AML1 were detected. The discrepant results between simultaneous RT-PCR and cytogenetic analysis were found in 11 cases. Nine cases were positive by simultaneous RT-PCR but negative in the cytogenetic analysis and each case of variant t(9; 22) and t(15; 17) was negative in simultaneous RT-PCR. Conclusions: It suggests that the simultaneous RT-PCR assay is an efficient and fast procedure for the detection of genetic changes in acute leukemia and it appears to be an useful method for rapid diagnosis of acute leukemia.

BACKGROUND: In renal transplantation, a good HLA-DR match Is associated with successive graft outcome. But due to a number of technical problems, reliable serological DR typing cannot always be obtained. To compare the serological DR typing with DRBI DNA typing, we tested 103 specimens that had been frozen after serological typing, by PCR-SSOP typing method. METHODS: Serological DR typing was performed by complement-dependent microlymphocytotoxicity technique using commercial antisera kits, and DNA gyp ins was performed by PCR-SSOP, using one of the methods recommended by 12th International Histocompatibility Workshop. DNA amplification was done by DRBAMP-A and DRBAMP-B primers, and hybridization by 18 oligonucleotides labelled with digoxigenin.. RESULTS: The concordance rate between serologic typing and DNA typing was 76.7%. Most (79.0%) of discordant results were due to serological blanks turning out to be definable antigens by DNA typing and these antigens consisted of mainly DR5 splits but none of DR1, DR2, or DR7. CONCLUSIONS: In spite of technical improvement, serological typing method often can not define the accurate HLA-DR type. It is thought that combining serological typing with DNA typing Is necessary to achieve a higher success rate of graft outcome.

Prenatal chromosome analysis of amniotic cells at 18 weeks of gestation showed a male fetus to carry a large 15p+ derivative chromosome inherited from his mother. Extra genetic material on the short arm of chromosome IS was silver-negative with Ag-NOR (nucleolus organizer regions) stain, but stained darkly with C-banding method like the distal heterochromatic segment of the Y long arm. Fluorescence in situ hybridization (FISH) using two DNA probes (DYZ1 and D15Zl) showed a red fluorescent signal on 15p+ In addition to a green chromosome 15 centromere signal, confirming 15p to be from the distal Yq heterochromatin.
