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.

Characterization and spatiotemporal expression of gonadotropin-releasing hormone in the Pacific abalone, <i>Haliotis discus hannai</i>

Kim, Tae Ha,Kim, Mi Ae,Kim, Kyeong Seop,Kim, Jae Won,Lim, Han Kyu,Lee, Jung Sick,Sohn, Young Chang Elsevier 2017 Comparative biochemistry and physiology. Part A, M Vol.209 No.-

<P><B>Abstract</B></P> <P>Gonadotropin-releasing hormone (GnRH) is a key neuropeptide regulating reproduction in humans and other vertebrates. Recently, GnRH-like cDNAs and peptides were reported in marine mollusks, implying that GnRH-mediated reproduction is an ancient neuroendocrine system that arose prior to the divergence of protostomes and deuterostomes. Here, we evaluated the reproductive control system mediated by GnRH in the Pacific abalone <I>Haliotis discus hannai</I>. We cloned a prepro-GnRH cDNA (<I>Hdh-GnRH</I>) from the pleural-pedal ganglion (PPG) in <I>H. discus hannai</I>, and analyzed its spatiotemporal gene expression pattern. The open reading frame of <I>Hdh-GnRH</I> encodes a protein of 101 amino acids, consisting of a signal peptide, a GnRH dodecapeptide, a cleavage site, and a GnRH-associated peptide. This structure and sequence are highly similar to GnRH-like peptides reported for mollusks and other invertebrates. Quantitative polymerase chain reaction demonstrated that <I>Hdh-GnRH</I> mRNA was more strongly expressed in the ganglions (PPG and cerebral ganglion [CG]) than in other tissues (gonads, gills, intestine, hemocytes, muscle, and mantle) in both sexes. In females, the expression levels of <I>Hdh-GnRH</I> mRNA in the PPG and branchial ganglion (BG) were significantly higher at the ripe and partial spent stages than at the early and late active stages. In males, <I>Hdh-GnRH</I> mRNA levels in the BG showed a significant increase in the partial spent stage. Unexpectedly, <I>Hdh-GnRH</I> levels in the CG were not significantly different among the examined stages in both sexes. These results suggest that <I>Hdh-GnRH</I> mRNA expression profiles in the BG and possibly the PPG are tightly correlated with abalone reproductive activities.</P>

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.

Effects of Panax ginseng on Morphine-induced Immune Suppression

Kim, Kyeong Man,Kim, Young Ran,Lee, Shee Yong,Kim, Ae Young 한국응용약물학회 1995 Biomolecules & Therapeutics(구 응용약물학회지) Vol.3 No.3

To investigate the possibility of Panax ginseng as a therapeutic agent for the immune suppression, ginseng total saponin (GTS) extracted from korean red ginseng was tested on immune functions from morphine-induced immune suppressed mice. To study how immune functions are affected by morphine and also to test whether GTS can be an useful therapeutic agent for morphine toxicity, several parameters were employed, body weight, immune organ weight, B cell functions, and T cell function. Morphine impaired the development of body weight and immune organ weight such as spleen and thymus. Morphine also depressed a B-cell function, antibody production. T-cell functions studied by type IV hypersensitivity test were most markedly affected by morphine treatment. GTS restored most of morphine-induced immune suppression. GTS restored the morphine-induced decrease in spleen weight to body weight ratio in a dose dependent manner, but not the body weight decrease. Also all of the morphine-induced impairments of B cell functions and cellmediated immunity were fully recovered by GTS. These results suggest that ginseng product could be very helpful for the treatment of immune suppression occurring in morphine abusers.

<P>Gastrin-releasing peptide receptor (GRPR) is overexpressed by a variety of human tumors and in particular, identified to be upregulated in prostate cancers. The current study aimed to develop clinically translatable BBN analogue-based radioligands for positron emission tomography (PET) of GRPR-positive tumors. We developed radiolabeled BBN analogues and modified radiolabeled galacto-BBN analogues and then investigated their tumor-targeting efficacy in vivo. The chelator 1,4,7-triazacyclononane, 1-glutaric acid-4,7 acetic acid (NODAGA) was used to radiolabel the peptides with Cu-64. The peptides were evaluated by measuring cell-based receptor-binding affinities. Biodistribution experiments and small animal imaging using PET were performed in nude mice bearing subcutaneous PC3 human prostate cancer xenografts. The conjugates were radiolabeled with yields >99%. The stability assay showed that [Cu-64] NODAGA-BBN and [Cu-64]NODAGA-galacto-BBN remained stable in both human and mouse serum for 1 h at 37 degrees C. PET images of PC3 tumor-bearing nude mice were acquired at 1, 3, 24, 48 and 72 h after injection. [64Cu]NODAGA-galacto-BBN showed retention in tumors for 72 h, low liver uptake, and rapid renal clearance. PET imaging results were also confirmed by biodistrubution 1 and 3 h after injection. [Cu-64]NODAGA-BBN and [Cu-64]NODAGA-galacto-BBN are promising new PET probes for GRPR-positive prostate cancer.</P>

Purpose: The goal of oncoplastic breast surgery is to restore the appearance of the breast and improve patient satisfaction. Thus, the assessment of cosmetic results and patient-reported outcomes (PROs) using appropriately constructed and validated instruments is essential. The aim of the present study was to assess the long-term objective cosmetic results and corresponding PROs after oncoplastic breast surgery. Methods: Cosmetic results were assessed by the patients, a medical panel, and a computer program (BCCT.core). PROs were assessed using BREAST-Q, a questionnaire that measures the perception of patients having breast surgery. The cosmetic results and PROs were analyzed in patients who underwent quadrantectomy and partial breast reconstruction utilizing the latissimus dorsi flap. Results: The mean duration of the follow-up period was 91.6 months (range, 33.3–171.0 months), and mean age of the patients was 51 years old (range, 33–72 years). The mean tumor size was 2.1 cm (range, 0.9–5.5 cm). There was fair agreement between the medical panel and BCCT.core score (K = 0.32, P < 0.001), and a statistically significant correlation between the BCCT.core score and medical panel cosmetic results was identified (r = 0.606, P < 0.001). A better BCCT.core result was related to a higher PRO of each BREAST-Q domain—satisfaction with breasts (R<SUP>2</SUP> = 0.070, P = 0.039), satisfaction with outcome (R2 = 0.087, P = 0.021), psychosocial well-being (R<SUP>2</SUP> = 0.085, P = 0.023), sexual well-being (R<SUP>2</SUP> = 0.082, P = 0.029), and satisfaction with information (R<SUP>2</SUP> = 0.064, P = 0.049). Conclusion: Our long-term results of oncoplastic surgery achieved a high level of patient satisfaction with good cosmetic results. The medical panel and BCCT.core results correlated well with the PROs of the patients using valid, reliable, and procedure-specific measures.
