Seeing through the reference of literatures ${\ll}$Internal Classic${\gg}$, ${\ll}$Donguibogam${\gg}$ and Master Jisan's theory about Ki-Hyul and Hyul-Ki, the writer came to conclusions as follows. In ${\ll}$Internal Classic${\gg}$ Ki-Hyul is expressed into being orderly and ordinate, but Hyul-Ki is described differently into making Hyul-Ki or operating Hyul-Ki. In ${\ll}$Donguibogam${\gg}$ Ki-Hyul and Hyul-Ki are not distinguished between two things, but Ki-Hyul is mentioned as harmony of Ki-Hyul and Hyul-Ki, and Hyul-Ki as ascending and descending or as deficiency and excess. In Hyungsang medicine the special characters of Ki-Hyul is seized the essence of the meanings from the deflection between left and right, changes of skin, flesh, meridian, muscle and bones. And the distinctive marks of Hyul-Ki is got hold from changes of complexion, many or few hairs, ascending or descending spirits of ears, eyes, mouth and nose. Also Ki-Hyul is recognized by laying stress on rise and fall, after birth, breast, upper limbs, eight extra meridians. And Hyul-Ki is recognized by laying stress on going up and down, the inborn constitution, abdomen, lower limbs, and twelve meridians. Jisan distinguished Ki-Hyul from Hyul-Ki theoretically and he applied the theory to clinical examination proved the facts that the theory and the examination are in accord with each other. This attempts was for the first time in Oriental medicine history and the theory was set up. It is thought that the defects of the theory about Ki-Hyul and Hyul-Ki which Jisan insisted on need much more study from now on.

The impact of folate on health and disease, particularly pregnancy complications and congenital malformations, has been extensively studied. Mandatory folic acid fortification therefore has been implemented in multiple countries, resulting in a reduction in the occurrence of neural tube defects. However, emerging evidence suggests increased folate intake may also be associated with unexpected adverse effects. This literature review focuses on contemporary issues of concern, and possible underlying mechanisms as well as giving consideration the future direction of mandatory folic acid fortification. Folate fortification has been associated with the presence of unmetabolized folic acid (PteGlu) in blood, masking of vitamin $B_{12}$ deficiency, increased dosage for anti-cancer medication, photo-catalysis of PteGlu leading to potential genotoxicity, and a role in the pathoaetiology of colorectal cancer. Increased folate intake has also been associated with twin birth and insulin resistance in offspring, and altered epigenetic mechanisms of inheritance. Although limited data exists to elucidate potential mechanisms underlying these issues, elevated blood folate level due to the excess use of PteGlu without consideration of an individual's specific phenotypic traits (e.g. genetic background and undiagnosed disease) may be relevant. Additionally, the accumulation of unmetabolized PteGlu may lead to inhibition of dihydrofolate reductase and other enzymes. Concerns notwithstanding, folic acid fortification has achieved enormous advances in public health. It therefore seems prudent to target and carefully monitor high risk groups, and to conduct well focused further research to better understand and to minimize any risk of mandatory folic acid fortification.

Purpose: Traditional radical surgery for vulvar cancer produces severe skin and soft tissue defects in the vulvar and vaginal area. Vulvoperineal V-Y advancement fasciocutaneous flaps have limitations in advancement and tension at the wound margin and vaginal orifice area, causing wound disruption or vaginal wall exposure. Therefore, we designed the "Butterfly flap" using a vulvoperineal V-Y advancement fasciocutaneous flap and an inguinal rotational skin flap for 3-dimensional reconstruction of vagina and vulvar area. Methods: A 27 year-old female was diagnosed with vulvar intraepithelial neoplasia. Radical vulvectomy and full-thickness-skin-graft was performed. We designed a vulvoperineal V-Y advancement fasciocutaneous flap as the greater wing and inguinal rotational skin as the lesser wing. After flap elevation, the inguinal flap was rotated $180^{\circ}$ to reconstruct the labia major and vaginal orifice. The perineum was reconstructed using V-Y advancement flaps. Results: The flap survived completely, without any complications. After 6 months, the patient was able to perform normal sexual activities and after 18 months, the patient was able to give birth to normal child by caesarean section. Conclusion: The traditional vulvoperineal V-Y advancement fasciocutaneous flap is thin, reliable, easily elevated and matches local skin quality. However, the vaginal wall becomes exposed due to limited advancement and tension of the flap. The "Butterfly flap" using a vulvoperineal V-Y advancement fasciocutaneous flap and an inguinal rotational skin flap is useful for the release of vaginal orifice contracture, reconstruction of the labia major, and 3-dimensional reconstruction of vagina and vulvar area.

Objectives : Isolated cleft lip with or without cleft palate(CL/P) is among the most common human birth defects, with a prevalence of approximately 1 in 700 live births. The B-Cell Leukemia/lymphoma 3(BCL3) gene has been suggested as a candidate gene for CL/P based on association and linkage studies in some populations. This study tests for an association between markers in BCL3 and isolated, non-syndromic CL/P using a case-parent trio design, while considering parent-of-origin effects. Methods : Forty case-parent trios were genotyped for two single nucleotide polymorphisms(SNPs) in the BCL3 gene. We performed a transmission disequilibrium test(TDT) on individual SNPs, and the FAMHAP package was used to estimate haplotype frequencies and to test for excess transmission of multi-SNP haplotypes. Results : The odds ratio for transmission of the minor allele, OR(transmission), was significant for SNP rs8100239(OR=3.50, p=0.004) and rs2965169(OR=2.08, p=0.027) when parent-of-origin was not considered. Parentspecific TDT revealed that SNP rs8100239 showed excess maternal transmission. Analysis of haplotypes of rs2965169 and rs8100239 also suggested excess maternal transmission. Conclusions : BCL3 appears to influence risk of CL/P through a parent-of-origin effect with excess maternal transmission.

Our previous study found that two novel cancer-related genes, PRR11 and SKA2, constituted a classic gene pair that was regulated by p53 and NF-Y in lung cancer. However, their role and regulatory mechanism in breast cancer remain elusive. In this study, we found that the expression levels of PRR11 and SKA2 were upregulated and have a negative prognotic value in breast cancer. Loss-of-function experiments showed that RNAi-mediated knockdown of PRR11 and/or SKA2 inhibited proliferation, migration, and invasion of breast cancer cells. Mechanistic experiments revealed that knockdown of PRR11 and/or SKA2 caused dysregulation of several downstream genes, including CDK6, TPM3, and USP12, etc. Luciferase reporter assays demonstrated that wild type p53 significantly repressed the PRR11-SKA2 bidirectional promoter activity, but not NF-Y. Interestingly, NF-Y was only essential for and correlated with the expression of PRR11, but not SKA2. Consistently, adriamycin-induced (ADR) activation of endogenous p53 also caused significant repression of the PRR11 and SKA2 gene pair expression. Notably, breast cancer patients with lower expression levels of either PRR11 or SKA2, along with wild type p53, exhibited better disease-free survival compared to others with p53 mutations and/or higher expression levels of either PRR11 or SKA2. Collectively, our study indicates that the PRR11 and SKA2 transcription unit might be an oncogenic contributor and might serve as a novel diagnostic and therapeutic target in breast cancer.

Along with the widespread use of pesticides in the world, concerns over human health impacts are rapidly growing. There is a large body of evidence on the relationship between the exposure to pesticides and the elevated rate of chronic diseases such as different types of cancers, diabetes, neurodegenerative disorders like Parkinson, Alzheimer, and amyotrophic lateral sclerosis (ALS), birth defects, and reproductive disorders. This research assessed the health risk of pesticide residues by the dietary intake of vegetables collected from the agro-based markets of Dhaka, Bangladesh. As some of the banned pesticides were also found in vegetable samples, they may pose a higher risk because of cheaper availability and hence the government of Bangladesh should take strong measures to control these banned pesticides. Five organo phosphorus (chlorpyrifos, parathion, ethion, acephate, fenthion) and two carbamate (carbaryl and carbofuran) pesticide residues were identified in twenty four samples of two common vegetables (tomato and brinjal). The pesticide residues ranged from below a detectable limit (< 0.01) to 0.36 mg·kg^-1. Acephate, chlorpyrifos, ethion, and carbaryl were detected in only one sample, while co-occurrence occurred twice for parathion. Continuous monitoring and strict regulation should be enforced regarding the control of pesticide residues in fresh vegetables and other food commodities in Bangladesh.

Cerebral palsy is one of the most serious forms of disorders of the psychophysical development of children, which manifests itself in disturbances of motor functions, which are often combined with speech disorders, other complications of the formation of higher mental functions, and often with a decrease in intelligence. The article will discuss the speech disorder in children with cerebral palsy. Emphasis is placed on some important aspects, which should bear in mind, investigating the problem of specifics of speech development of children with cerebral palsy. In particular at the heart of speech disorders in the cerebral palsy is not only damage to certain structures of the brain, but also the later formation or underdevelopment of those parts of the cerebral cortex, which are of major importance in linguistic and mental activity. This is an ontogenetically young region of the cerebral cortex, which is most rapidly developing after birth (premotor, frontal, temmono-temporal). It is important to take into account, that children with cerebral palsy have disturbances of phonemic perception. Often, children do not distinguish between hearing sounds, cannot repeat component rows, allocate sounds in words. At dysarthria, there are violations of pronunciation of vowel and consonant sounds, tempo of speech, modulation of voice, breathing, phonation, as well as asynchronous breathing, alignment and articulation. As a result, we identified the main features and specifics of the speech development of children with cerebral palsy and described the conditions necessary for the full development of language. Language disturbances in children's cerebral palsy depend on the localization and severity of brain damage. Great importance in the mechanism of speech disorders has a pathology that limits the ability of movement and knowledge of the world.

Objective: To compare the utility of computed tomography perfusion (CTP) and three different 4-point scoring systems in computed tomography angiography (CTA) in confirming brain death (BD) in patients with and without skull defects. Materials and Methods: Ninety-two patients clinically diagnosed as BD using CTA and/or CTP for confirmation were retrospectively reviewed. For the final analysis, 86 patients were included in this study. Images were re-evaluated by three radiologists according to the 4-point scoring systems that consider the vessel opacification on 1) the venous phase for both M4 segments of the middle cerebral arteries (MCAs-M4) and internal cerebral veins (ICVs) (A60-V60), 2) the arterial phase for the MCA-M4 and venous phase for the ICVs (A20-V60), 3) the venous phase for the ICVs and superior petrosal veins (ICV-SPV). The CTP images were independently reviewed. The presence of an open skull defect and stasis filling was noted. Results: Sensitivities of the ICV-SPV, A20-V60, A60-V60 scoring systems, and CTP in the diagnosis of BD were 89.5%, 82.6%, 67.4%, and 93.3%, respectively. The sensitivity of A20-V60 scoring was higher than that of A60-V60 in BD patients (p < 0.001). CTP was found to be the most sensitive method (86.5%) in patients with open skull defect (p = 0.019). Interobserver agreement was excellent in the diagnosis of BD, in assessing A20-V60, A60-V60, ICV-SPV, CTP, and good in stasis filling (κ: 0.84, 0.83, 0.83, 0.83, and 0.67, respectively). Conclusion: The sensitivity of CTA confirming brain death differs between various proposed 4-point scoring systems. Although the ICV-SPV is the most sensitive, evaluation of the SPV is challenging. Adding CTP to the routine BD CTA protocol, especially in cases with open skull defect, could increase sensitivity as a useful adjunct.

목 적 : 듀시엔/베커형 근이영양증(Duchenne and Becker type muscular dystrophy; DMD/BMD)은 남아에게 나타나는 일반적인 X 염색체 연관 유전성 근육 질환으로 DMD(dystrophin) 유전자의 돌연변이로 인해 생긴다. 그 중 큰 exon 결실이 전체 DMD 환자의 약 50-60%에서 발견된다. 이 유전자의 돌연변이를 찾기 위해 여러 방법들이 사용되고 있지만 결실 돌연변이를 찾아내기 위한 가장 일반적인 방법으로 복합적 중합효소연쇄반응을 이용하고 있다. 하지만 이 방법의 단점은 하나의 시험관 안에 복합적인 시발체가 존재하여 정확한 반응 조건을 찾기 힘들 뿐 아니라 시발체 상호간의 간섭으로 중합효소 연쇄반응의 비특이적 생성물을 빈번하게 일으켜 잘못된 음성 또는 양성 결과를 가져올 수 있다. 이런 문제를 보완하고자 Dual Primer Oligonucleotide(DPO) 방법을 도입하였다. DPO는 polydeoxyinosine 연결에 의해 두 영역으로 분리된 올리고뉴클레오티드(oligonucleotide)로 표적 DNA 염기서열과의 교잡반응에 높은 특이적 반응을 보여 복합 중합효소 연쇄반응의 정확도를 높여준다. 본 연구에서는 3 그룹을 대상군으로 DMD 유전자의 결실돌연변이 검색을 위한 DPO-복합 중합효소 연쇄반응법의 특이성과 민감성을 알아보고자 하였다. 방 법 : 50명의 건강한 남자 대조군, 50명의 결실 돌연변이를 갖고 있는 양성반응 환자그룹 그리고 20명의 결실 돌연변이를 가지고 있지 않은 음성반응 환자 그룹으로 구성된 3 그룹을 대상으로 DPO-복합 중합효소 연쇄반응법을 이용하여 실험하였다. 이들 120명의 실험군 모두 PMter영역과 exon 3, 4, 6, 8, 12, 13, 17, 19, 43-48, 50-52, 60을 포함하는 18개의 exon에서의 결실의 여부와 결실 범위를 확인하였다. 결 과 : DPO-복합 중합효소 연쇄반응법은 결실 여부를 발견하는데 100%의 특이성과 민감성을 보였다. 하지만 결실 범위의 결정에는 97.1%의 민감성과 특이성을 보였다. 결 론 : DPO-복합 중합효소 연쇄반응법은 기존의 복합 중합효소 연쇄반응법 보다 높은 분석 확실성을 보일뿐 아니라 빠르고 저렴한 비용으로 쉽게 할 수 있기 때문에 듀시엔/베커형 근이영양증 환자의 DMD 유전자의 결실돌연변이 여부를 확인하는데 유용한 방법이다.
