Ventricular septal defect remains an infrequent but devastating complication of acute MI. Approximately 1∼3% of cases of acute myocardial infarction are complicated by ventricular septal rupture in the prethrombolytic era and the incidence has decreased to 0.2% with reperfusion therapy. This mechanical complication usually occurs within the first 10 to 14 days when necrotic tissue is most abundant and the collateral coronary circulation is not well developed. This lesion is generally associated with complete coronary obstruction rather than severe stenosis. Rupture of the ventricular septum is a severe mechanical complication of acute myocardial infarction, usually resulting in death unless surgical repair is performed. The bad prognosis of this event within the first 2 weeks indicates the need for early surgical rapair. This complication is more frequent after the first acute myocardial infarction in the elderly and secondary to a transmural myocardial infarction. We report two cases of ventricular septal rupture after acute myocardial infarction.

Background:Although Alzheimer's disease (AD) is a progressive neurodegenerative disorder without any truly effective pharmacological treatment at present, early accurate diagnosis is important for the delaying of disease progression and proper management It would be desirable to have a peripheral biological marker to identify patients affected by AD Amyloid β-peptide originates from a larger precursor, the amyloid precursor protein (APP). which can be seen in the platelet of its equivalent to those found in brain. To investigate if there is a correlation between level of platelet APP isoform and AD, we evaluate a cohort of subjects including patients affected by sporadic AD, vascular dementia, and controls Subjects & Methods :Thirty-five patients with sporadic AD diagnosed according to the National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Relatec Disorders criteria (NINCDS-ADRDA) and 26 vascular dementia patients diagnosed by the Diagnosis and Statistical Manual of Mental Disorders, Fouth Edition (DSM-Ⅳ) criteria and 12 controls were included Blood sample were drawn from fasting state and collected into 3 mL of 3.8% sodium citrate. Platelets were collected by centrifugation at 500 g for 20 minutes and washed. and the platelet pellet was stored at -80℃ until used APP was assessed by western blot analysis and quantified by densitometry using Image Analyzer Results:In platelets densitometer as well as the result of Western blot was higher compared with those of patients with non-Alzheimer dementia and controls We observed statistically significant reductions in the ratio of 120 kDa to 130 kDa APP to 110 kDa APP (APPr) for patients with probable AD compared with control subjects and patients with vascular dementia APPr levels in AD correlated with the severity of dementia measured by CDR. Accuracy levels measured by Receiver Operating Curve analysis showed that a cut-off level of 0.45 resulted in a sensitivity of 71% and a specificity of 74%, with an area under the curve of 0 793 Conclusion:Platelet APPr allowed to differentiate AD from normal aging and vascular dementia with high sensitivity and specificity These findings suggest that platelet APPr may be a helpful peripheral marker for diagnosis and clinical progression of Alzheimer disease.

This study was conducted to examine the correlation among growth development, bone mineral density, and nutrient intakes in preschool children. A total of 62 preschool children measured the anthropometric characteristics and the bone mineral density of carpus using DEXA. The questionnaires categorized to determine health status, life style, dietary behaviors, and dietary intakes were filled out by children's mothers. The average ages of the study subjects were 62.4 months in boys and 62.1 months in girls. The birth height and weight of the subjects were 50.9 ㎝ and 3.4 ㎏ in boys and 50.3 ㎝ and 3.3 ㎏ in girls, respectively. The average height, weight, % body fat, and obesity index were 111.7 ㎝, 19.6 kg, 15.0%, -2.1% in boys and 109.4 ㎝, 18.7 ㎏, 17.5%, 0.2% in girls, respectively. The bone mineral density in carpus was 0.25 g/㎠ in boys and 0.24 g/㎠ in girls. Proportions of children having regular meals were 69.0%, 94.7% and 69.0% for breakfast, lunch, and dinner, respectively. The major reasons for irregular meal were poor appetite and lack of time for breakfast and snacks for dinner. Most of the children(52.6%) had breakfast with the whole family together, and all the children had lunch and dinner with a part of the family. Most of the children answered they had snack more than once a day, and 64.3% had an unbalanced diet. The intakes of energy, calcium, iron, zinc, vitamin A, vitamin B₁, niacin, and vitamin C did not meet the Korean RDAs. The intakes of energy, calcium, iron, zinc, vitamin A, vitamin B₁, niacin, and vitamin C did not meet the Korean RDAs. Average bone mineral density in carpus was positively correlated to the body weight, the total body water, the lean body mass, and obesity index, respectively(p<0.01, p<0.01, p<0.01 and p<0.01). The body weight, the total body water, and the lean body mass showed the significant negative correlation with the animal iron intake(p<0.05, p<0.01 and p<0.01). The bone mineral density the distal carpus was negatively correlated to the animal protein intake and the animal iron intake(p<0.05 and p<0.05). And the bone mineral density in the ultradis carpus and the average bone mineral density in the carpus were positively correlated to the plant calcium intake(p<0.05 and p<0.05). Therefore, more systematic studies to investigate the roles of protein, iron, and calcium in growth development of preschool children were required.

Effects of Morphine and Panax ginseng on the Opioid Receptor-G protein Interactions

Kim, Kyeong Man,Kim, Young Ran,Kim, Ae Young 한국응용약물학회 1999 Biomolecules & Therapeutics(구 응용약물학회지) Vol.7 No.1

Effects of Panax ginseng on the morphine toxicity were studied in relation to its effects on the opioid receptor-G protein interactions. Morphine treatments (3 days) reduced the body weight increment rate and the weight of the thymus and spleen. These changes were usually recovered by the concomitant administration of ginseng total saponin (GTS) but occasionally further deteriorated. This discrepancy was studied in relation to the opioid receptor coupling to G protein, that is, the effects of morphine and GTS on the opioid receptors were studied using the antagonist-agonist competitive binding studies. When GTS recovered the morphine toxicity, morphine shifted the striatal 8 receptors to slightly higher affinity state, and this was partly recovered by the GTS treatment. However, morphine did not have any effect on the affinity state of δreceptor from NG108-15 cells, suggesting that additional factors were needed for the modulation of the affinity states of δreceptor. Effects of morphine and GTS on μreceptor were complicate and variable, and we could not reach a clear conclusion. The morphine toxicity might accompany complicate biological involvements, and the modulation of the affinity states of the opioid receptors might explain a part of the effects of GTS on the morphine toxicity.

Molecular Cloning and Characterization of a cDNA Encoding Caprine β - Lactoglobulin

Kim, Ji Young,Yu, Myeong Hee,Kim, Ae Kyeong,Kim, Jae Man 한국유전학회 1993 Genes & Genomics Vol.15 No.2

The complete sequence of caprine β-lactoglobulin cDNA has been determined. The caprine β-lactoglobulin cDNA consists of 540 nucleotide coding region, flanked by 40 nucleotide 5'-untranslated region (UTR) and 207 nucleotide 3'-UTR which was followed by 78 nucleotide polyadenylation. The coding region encodes 180 amino acids which consist of l8 amino acid-long signal peptide and 162 amino acid-long mature β-lactoglobulin. The caprine β-lactoglobulin cDNA differs from that of its ovine counterpart by 7 nucleotides in the protein coding sequence resulting in 2 amino acid changes at amino acid positions -3 and +130. The nucleotide sequence at 5' -UTR and coding region was highly conserved with respect to the ovine β-lactoglobulin and was more homologous to ovine cDNA (99%) than the bovine cDNA (94%). However, the 3' -UTR of the caprine β-lactoglobulin mRNA was less conserved and it is more homologous to bovine cDNA (94%) than that of the ovine mRNA (90%). The sequence analysis revealed that the β-lactoglobulin molecules are highly conserved during the evolution of ruminant species.

Generation and Characterization of Cell-Permeable Green Fluorescent Protein Mediated by the Basic Domain of Human Immunodeficiency Virus Type 1 Tat

Kim, Kyeong Ae,Choi, Eui Yul,Choi, Soo Young,Park, Jin Seu,Ryu, Ji Yoon,Lee, Kil Soo 한국미생물 · 생명공학회 2000 Journal of microbiology and biotechnology Vol.10 No.6

The human immunodeficiency virus type 1 (HIV-1) Tat is one of the viral gene products essential for HIV replication. The exogenous Tat protein is transduced through the plasma membrane and then accumulated in a cell. The basic domain of the Tat protein, which is rich in arginine and lysine residues and called the protein transduction domain (PTD), has been identified to be responsible for this transduction activity. To better understand the nature of the transduction mediated by this highly basic domain of HIV-1 Tat, the Green Fluorescent Protein (GFP) was expressed and purified as a fusion protein with a peptide derived from the HIV-1 Tat basic domain in Escherichia coli. The transduction of Tat-GFP into mammalian cells was then determined by a Western blot analysis and fluorescence microscopy. The cells treated with Tat-GFP exhibited dose-and time-dependent increases in their intracellular level of the protein. The effective transduction of denatured Tat-GFP into both the nucleus and the cytoplasm of mammalian cells was also demonstrated, thereby indicating that the unfolding of the transduced protein is required for efficient transduction. Accordingly, the availability of recombinant Tat-GFP can facilitate the simple and specific identification of the protein transduction mediated by the HIV-1 Tat basic domain in living cells either by fluorescence microscopy or by a fluorescence-activated cell sorter analysis.
