Vitamin D and carotid subclinical atherosclerosis in SLE Chang-Bum Bae, Ju-Yang Jung, Bo-ram Go, Hyun-Ah Kim, Chang-Hee Suh Department of Rheumatology, Ajou University School of Medicine, Suwon, Korea Introduction Atherosclerosis develops earlier in systemic lupus erythematosus (SLE) and is the important cause of mortality. It has been suggested that vitamin D deficiency contributed cardiovascular disease and immune dysregulation in SLE. Methods One-hundred two female patients with SLE and 52 normal controls (NC) were recruited. The carotid artery intima-media thickness (cIMT) and plague were assessed by B-mode ultrasound at the carotid artery level. Vitamin 25(OH)D3 levels were checked by immunoradiometric assay using the Bio-Line 25(OH)D3-Ria CT kit (Bio-Line S.A., Belgium). Disease activity markers were checked at the time of enrollment. Results The cIMT of SLE is 0.41±0.08mm, which is higher than NC (0.37±0.11 mm, p=0.012). Also, carotid artery plague index (PI) of SLE is higher than NC (0.68±1.39 vs 0.26±0.87, p=0.026). The cIMT was correlated with age (r=0.442, p<0.001), body mass index (r=0.246, p=0.013), waist-hip ratio (r=0.245, p=0.013), SLE disease activity index (r=0.239, p=0.016), taking aspirin (r=0.244, p=0.013), and the carotid artery PI was correlated with renal involvement (r=0.224, p=0.023) in patients with SLE. Vitamin 25(OH)D3 was not showed correlation with cIMT and carotid artery PI. Also, it was not correlated with disease activity markers. Conclusion In patients with SLE, the risk of cardiovascular disease measured by cIMT and carotid artery plaque was higher than NC, which may be derived from systemic inflammation. However, vitamin D levels were not showed significant correlations with carotid subclinical atherosclerosis. It may be not suitable to assess vitamin D as marker of disease activity or subclinical atherosclerosis.

When defect levels in a process become very low say under PPM(parts per million), there will be very long periods of time between the occurrence of a nonconforming unit. The 3σ control limits of conventional control chart has some problems at PPM environments. Thus, concentional p and c chart become ineffective as defect levels are driven into the low PPM range. In this paper p and c chart suggested by Goh is shown the best way.

본 연구는 3요소(N-PO_2O_5-K_2O)처리가 산국(Chysanthemum boreale M.)의 수량과 유효성분에 미치는 효과를 조사하여 효과적인 재배시스템을 개발하고자하였다. 처리구는 무처리, NPK(250-160-160), NK(250-0-160), PK(0-160-160kg/ha)의 5처리로 설정하여 산국을 재배한 결과, 건물수량은 NPK처리구가 PK처리구에 비하여 4.0배의 증수가 있었으며, 다른 처리구보다 무기이온의 흡수율, 생육 및 수량에서 NPK처리구가 가장 우수하였다. 식용으로 많이 쓰이는 꽃의 주요 아미노산은 proline, glutamic acid과 aspartic acid이였고, 다른 처리구들에 비하여 NPK처리구가 높은 함량을 보였다. 혈압강하효과가 우수한 cumambrin A는 PK처리구에 비하여 NPK처리구가 6.2배의 증수효과가 있었다. NK처리구는 NP처리구보다 cumambrin A의함량을 높이기 위해서는 인산의 시용보다 칼리의 시용이 더 요구되며, 야외포장에서의 인산과 칼리의 적정 시비량의 설정이 필요하다고 판단된다. To establish the fertilization condition to increase the productivity of Chrysanthemum boreale M. with high quality, the effects of three nutrients (N, P, K) on the yields and the effective components were investigated in the pot scale. NPK was applied by chemical fertilizers with N-P_2O_5-K_2O = 250-160-160 kg/ha as a main treatment, and NP (N-P_2O_5 = 250-160 kg/ha), NK (N-KO = 250-160 kg/ha), and PK (PO_2-KO_5 = 160-160 kg/ha) treatments were settled as comparison. Dry yields of C. boreale M. was increased significantly to 4 fold higher by nitrogen. Nitrogen increased apparently plant growth and inorganic nutrient uptake. In the flower, which is most useful and edible part as a herbal medicine, main amino acids were glutamic acid and aspartic acids, and the total content was increased significantly by three elements of application. In addition, the content of cumambrin A, which is known to have the effect of blood-pressure reduction, was increased source to 6.2 times by nitrogen higher than that in PK treatment. Potassium was more effective in biosyndiesis of cumatnbrin A than phosphorus, but the biological pathway was not clear, still.

This paper described a collaborative exercise intended to see what kinds of short tandem repeat (STR) loci are used in different DNA typing laboratories in Korea and to compare their results for the demonstration whether uniformity of DNA profiling results from different laboratory could be achieved in Korea Laboratories were asked to test five tissue DNAs using methods routinely used in each laboratory and to report the results to the coordinating laboratory. The exercise demonstrated that each laboratory was using different STR loci for the typing with different STR numbers,2 VNTRS,36 STRs and amelogenin in total, and the direct comparison of the results from all the laboratory for the 18 loci could not be done as only one laboratory submitted typing results. Among 21 loci for which several laboratories submitted typing results, results for 14 loci were the same and results for the other 7 loci were different depending on the participating laboratory. D1S80, F13A01, D16S539, D21S11, D18S51, D3S1744 were the loci with different typing results. Even in the cases where commercial kits were used, the results were not the same depending on the machines used, that is the capillary electrophoresis or the gel based electrophoresis. The reason for the different results, points about the standardization of the methods arid the profiling data were described.

Purpose: Because the main drawback of bilateral adrenalectomy is permanent adrenal insufficiency and the subsequent risks of life-long steroid use, adrenal preserving partial adrenalectomy is being accepted as its alternative. The aim of this study is to investigate the indications for bilateral adrenalectomy and to assess the postoperative outcomes and steroid replacement according to operative methods. Methods: From May 1996 through July 2013, a total of 25 patients who underwent bilateral adrenalectomy in our institution were reviewed retrospectively. Surgical outcomes were compared between total and partial adrenalectomy, and postoperative steroid hormone replacement were examined according to the volume of remnant adrenal gland. Results: The median follow-up duration of 25 patients was 55.8 months. The most common indication for bilateral adrenalectomy was bilateral pheochromocytoma (n=16), which was associated with genetic mutation of RET or VHL gene in 11 cases. Cushing's syndrome (n=8) and hyperaldosteronism (n=1) were another indications of bilateral adrenalectomy. Total adrenalectomy was performed in 8 patients and adrenal preserving partial adrenalectomy in 17 patients. Among the 17 patients, only 5 patients needed adrenal hormone replacement and 2 patients had a recurrence at remnant adrenal tissue. Conclusion: Adrenal preserving partial adrenalectomy might be a better option for bilateral adrenal tumor than total adrenalectomy because it can reduce complications associated with adrenal insufficiency and recurrence of the disease is not common.

약용식물내 에스트로겐성과 항-에스트로겐성을 조사하고 항암인자를 발견하기 위하여, 본연구는 에탄올추출로 제조된 9종류의 한국산 약용식물에 대하여 재조합효모와 MCF-7 사람유방암세포주를 이용하여 스크리닝하고 비교하였다. 재조합효모를 이용한 실험결과, 7종류의 약용식물에서 에스트로겐성이 나타났고, 4종류에서 안드로겐성이 나타났다. 또한 MCF-7 사람유방암세포주를 이용한 실험결과, 8종류의 추출물이 MCF-7 세포의 성장을 억제하는 것으로 확인되었으며 비스페놀 A와 동시 처치한 경우에도 유의적으로 억제하는 것으로 나타났다. 또한 Clyeyrrhiza uralensis, Cassia tora, Syringa velutina, Zingiber officinale, Malva verticillata, Panax ginseng C.A. Meyer는 식물성 에스트로겐으로서 에스트로겐에 양성인 사람유방암세포의 증식을 유의적으로 억제시티는 흥미로운 결과가 제시되었다. 따라서 이번 연구는 한국산 약용식물이 식물성 에스트로겐과 항암인자로서 이용될 수 있으며, 에스트로겐의 활성을 조사하는데 유용하게 이용될 수 있을 것으로 사료된다. To investigate whether there are estrogenic and anti-estrogenic activities in various medicinal herbs and discover prominent chemo-preventive agents, eye screened and compared the ethanol extracts of 9 plants through the recombinant yeast assay and MCF-7 human breast cancer cell assay. In recombinant yeast assay. seven medicinal herbs showed estrogenicity, and tour extracts showed androgenecity. In MCF-7 proliferation assay. the growth of MCF-7 cells was inhibited by eight extracts before and even alter co-treatment with bisphenol A. It is interesting that the extracts of Glyeyrrhiza uralensis, Cassia tora, Syringa velutina, Zingiber officinale, Malva verticillata, and Ponax ginseng C.A. Meyer exhibited inhibitory effects as phytoestrogens in estrogen-responsive human breast cancer cells. This study suggests that some Korean medicinal herbs might be considered as phytoestrooens and be useful to further analyze those plants which contain the estrogenic effect in order to identify the active principles.

Gangliosides are a family of sialic acid-containing glycosphingolipids that are abundant in neurons and have a variety of functions in developing and mature tissues. We examined the expression of ganglioside GT1b in the embryonic preimplantation stage after freezing and thawing processes to determine the regulatory roles of ganglioside GT1b in early embryonic development. ICR mouse embryos at the two-cell stage obtained by flushing the oviducts were frozen by two cryopreservation procedures, slow freezing using a programmable freezer or vitrification by direct plunging into liquid nitrogen. Slow freezing was conducted with equilibration in 1.5 M 1,2-propanediol or 5% equilibration glycerol. Vitrification was applied with a 10-15 min equilibration in 7.5% ethylene glycol (EG), 7.5% dimethylsulfoxide (DMSO), and 30 sec in a solution of 15% EG, 15% DMSO and 0.5 M sucrose. Immediately after thawing, the survival rate of the embryos was assessed by their morphology and ability to develop to blastocysts in culture. The survival rate of vitrified and thawed embryos (92%) was significantly higher than that of slow frozen and thawed embryos (76%) (P<0.05). A tendency of higher blastocyst rate was found in the vitrified and thawed embryos compared to that of the slow frozen and thawed embryos. Confocal immunofluorescence staining confirmed that surviving embryos expressed ganglioside GT1b, with the strongest expression at the compacted eight-cell or later stage embryos. Ganglioside GT1b was not observed in the TUNEL-positive, apoptotic embryos, suggesting that cryopreservation had induced DNA breaks in them. These results suggest that ganglioside GT1b may play an important role in embryo survival or development.
