The purpose of this study is to propose a model for service programs and management strategies for the division of family education in Healthy Families Center. For the purpose, the researchers find out demands for the family education programs of people in Yong-San Gu, Seoul, exam the effect of each family education program of Yong-San Gu & Sookmyung Women's University Healthy Families Center from June to December, 2004. According to the results, people in Yong-San Gu need economic education service mostly, and they want to study at Saturday afternoon. The programs show positive effect on the improvement of family health.

We performed genetic analysis for detection of carrier state of Duchenne's muscular dystrophy (DMD). As genetic markers of the disorder, We used DNA-sequence polymorphisms detected with 6 different DNA probes derived from the vicinity of the DMD locus at genetic distance less than 15 cmo or from within the gene. on the short arm of X chromosome. In the family we studied. a consultand was a 29 years old woman whose maternal grandfather was a DMD patient who was unavailable. Therefore, all of her maternal aunts were DMD carriers whose next generations were requested for DNA studies. On the basis of linkage analysis. a proband and her niece were deemed to be unaffected with an accuracy of more than 99%, and we anticipated another two femals and one malt to be unaffected with 98% probability (normal serum creatine kinase level) where crossover events between intragenic(pERT 87.30) and flanking probes(pXUT23) were detected. but carrire risk of a female with the same haplotype was elevated to 41% taking account of an increased serum creatine kinase level. Two other females were predicted to be affected with 99.9 and 97.1% probabilities each. However. a genetic interpretation was impossible for one male in which a crossover breakpoint could not be determinied because of his mother's homozygosity of the alleles between crossovered alleles where hitherto pessibility of intragenic crossover could not be ruled out Our experience suggests that genetic diagnosis based on recombinant deoxyribonucleic acid techniques are assuming increasing importance. and provide a highly accurate method for carrier detection and prenatal diagnosis of DMD. By the way, despite the large number of intragenic and flanking DNA polymorhpisms available, uncertainties often remain in the genetic diagnosis of DMD. Pitfalls are presented by the large size of the region in which Duchenne's mutations can occur. Crossover events in this region. especially intragenic ones, which result in an exchange of DNA between two X chromosomes, can,rener DNA-marker studies inaccurate.
Molecular Characteristics of Two Laccase from the Basidiomycete Fungus Polyporus brumalis
Sun-Hwa Ryu,A-Young Lee,Myungkil Kim 한국미생물학회 2008 The journal of microbiology Vol.46 No.1
Two laccase cDNAs, pblac1 and pblac2, were cloned from a white-rot fungus strain, Polyporus brumalis (KFRI 20912). The cloned cDNAs consisted of 1,829 bp and 1,804 bp, and their open reading frames encoded proteins of 520 and 524 amino acids, with calculated molecular masses of approximately 55.9 kDa and 56 kDa, respectively. The deduced amino acid sequences of each protein showed 70% similarity. The copper binding regions were conserved in both proteins, as in other fungal laccases. RT-PCR analysis revealed that the transcript levels of the two laccases increased progressively in shallow stationary culture liquid medium. The transcript level of each laccase was induced when the fungus was exposed to di-butyl phthalate (DBP), suggesting that the two laccases are involved in DBP degradation. The overexpression of the pblac1 gene was derived by the promoter of a gene for glyceraldehyde-3-phosphate dehydrogenase, using a homologous system. The activity of laccase in the transformants was significantly higher than that of the wild type. The identification of these laccase cDNAs was a first step to characterize the molecular events related to the lignin degradation ability of this basidiomycetous fungus, as well as the degradation of many recalcitrant xenobiotics.

<P>Previously, the <I>swpa4 </I>peroxidase gene has been shown to be inducible by a variety of abiotic stresses and pathogenic infections in sweet potato (<I>Ipomoea batatas</I>). To elucidate its regulatory mechanism at the transcriptional level under various stress conditions, we isolated and characterized the promoter region (2374 bp) of <I>swpa4 </I>(referred to as <I>SWPA4</I>). We performed a transient expression assay in tobacco protoplasts with deletions from the 5′-end of <I>SWPA4 </I>promoter fused to the β-glucuronidase (GUS) reporter gene. The −1408 and −374 bp deletions relative to the transcription start site (+1) showed 8 and 4.5 times higher GUS expression than the cauliflower mosaic virus <I>35S </I>promoter, respectively. In addition, transgenic tobacco plants expressing GUS under the control of −2374, −1408 or −374 bp region of <I>SWPA4 </I>promoter were generated and studied in various tissues under abiotic stresses and pathogen infection. Gel mobility shift assays revealed that nuclear proteins from sweet potato cultured cells specifically interacted with 60-bp fragment (−178/−118) in −374 bp promoter region. In silico analysis indicated that four kinds of <I>cis</I>-acting regulatory sequences, reactive oxygen species-related element activator protein 1 (AP1), CCAAT/enhancer-binding protein alpha element, ethylene-responsive element (ERE) and heat-shock element, are present in the −60 bp region (−178/−118), suggesting that the −60 bp region might be associated with stress inducibility of the <I>SWPA4 </I>promoter.</P>
Clinical effectiveness of wireless CROS (contralateral routing of offside signals) hearing aids.
Ryu, Nam-Gyu,Moon, Il Joon,Byun, Hayoung,Jin, Sun Hwa,Park, Heesung,Jang, Kyu-Sun,Cho, Yang-Sun Springer International 2015 European archives of oto-rhino-laryngology Vol.272 No.9
<P>This study evaluated the clinical effectiveness of wireless contralateral routing of offside signals hearing aids (CROS) in patients with severe to profound unilateral sensorineural hearing loss (USNHL). Twenty-one patients with USNHL were enrolled in this prospective study. The change of subjective satisfaction was evaluated using three questionnaires (K-HHIE, K-IOI-HA, K-SSQ). Changes in objective measurements were evaluated with sound localization test (SLT) and hearing in noise test (HINT). These tests were performed at pre-CROS fitting, 2 and 4?weeks after use of CROS. Subjects were grouped according to the age: young (<40?years) vs. old (40?years) group. The average K-HHIE and K-SSQ scores significantly improved with the use of CROS. SLT result revealed that hit rate and error degree improved in the young group and lateralization ability improved in both groups. In quiet environments, the reception threshold for speech also indicated a significant benefit in the young group. When the noise was presented to the normal ear, HINT revealed benefit of CROS, while loss of performance with CROS use was significant when noise was presented to the impaired ear. Wireless CROS provided increased satisfaction and overall improvement of localization and hearing. Although true binaural hearing cannot be obtained, CROS is a practical option for rehabilitation of USNHL.</P>
난용성 약물인 Isoflavone계 화합물을 함유한 하이드로콜로이드 패치의 물리화학적 특성

Genistein과 daidzein은 isoflavone 계열의 약물로써 다양한 암의 치료 및 예방, 항산화, 항염 활성 효과를 나타내는 물질이다. 그러나 이 약물들은 용해성이 좋지 않아 약물을 포함하는 크림 형태의 에멀젼에 적용하여 피부를 통해 전달하기 어렵다. 본 연구에서는 하이드로콜로이드 패치라는 TDDS(transdermal drug delivery system)를 이용하여 genistein과 daidzein과 같은 난용성 약물을 피부에 전달하였다. 패치가 에멀젼보다 피부로 잘 흡수되는 것을 돼지 피부(porcine skin)를 이용한 투과 실험 및 confocal microscopy로 확인하였으며, 이는 패치의 밀폐효과(occlusive effect)에 의해 피부 내로 잘 흡수된 것이다. 하이드로콜로이드 패치는 에멀젼 형태의 크림보다 난용성 약물을 피부내로 전달하는데 더 좋은 방법이며, 사용하기 편리하므로 효과적인 화장품으로써 가치가 있다. Genistein and daidzein, phytoestrogens belonging to the isoflavone class, have a role in the treatment and prevention of various cancers, antioxidant and anti-inflammation activity. However, it is difficult to deliver through the skin from applying the emulsion such as cream containing them because these drugs are nearly insoluble in aqueous solutions. In this study, the hydrocolloid patch including poorly soluble drugs such as genistein and daidzein was used as the transdermal drug delivery system (TDDS) to deliver them through the skin. It was confirmed that the patches are helpful for the drugs to be absorb much and more deeply than the cream due to the occlusive effect of patch, which was verified from the porcine skin and the confocal microscopy. The hydrocolloid patch is a better way to deliver the poorly soluble drugs through the skin than the general cosmetics such as emulsion-based cream, and is valuable as effective cosmetics due to its convenient usage.
