Dietary Reference Intake of n-3 polyunsaturated fatty acids for Koreans

박용순 한국영양학회 2022 Nutrition Research and Practice Vol.16 No.3

This paper examines the process and evidence used to create the Dietary Reference Intake (DRI) of alpha-linolenic acid (ALA) and eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA) for Koreans. ALA (18:3n3) is an essential fatty acid, and EPA and DHA are known to have beneficial effects on cardiovascular disease risk and reduction of triglyceride levels. Various international organizations have suggested dietary recommendations for n-3 polyunsaturated fatty acids (PUFAs), including ALA, EPA, and DHA. A DRI for Koreans was established for the first time in 2020, specifically for the adequate intake (AI) of ALA and EPA + DHA. This recommendation was based on the average intake of ALA and EPA + DHA from the Korea National Health and Nutrition Examination Survey 2013–2017. For Korean infants, the AI of ALA and DHA was based on the fatty acid composition of maternal milk. Estimated average requirement and a tolerable upper intake level have not been set for n-3 PUFA due to insufficient evidence. In addition, the intake level of n-3 PUFA for prevention of chronic disease has also not been determined. Future studies and randomized controlled trials are required to establish the UL and to define the level for disease prevention.

Purpose: First introduced by Buncke and Rose in 1979, the neurovascular partial $2^{nd}$ toe pulp free tissue transfer has been attempted to reconstruct posttraumatic finger tip injuries. Although some surgeons prefer other reconstructive methods such as skin graft and local flap, we chose the partial $2^{nd}$ toe pulp flap owing to its many advantages. We report three successful surgical cases in which the patients had undergone this particular method of reconstruction. Methods: We retrospectively examined three cases of fingertip injury patients due to mechanical injury. Bone exposure was seen in all three cases, All had undergone partial toe pulp free flap for soft tissue defect coverage. Results: All flaps survived without any complications such as partial necrosis, hematoma or dehiscence. Although tingling sensation has returned in both cases, two-point discrimination has not returned yet. Currently no patient is complaining of any pain which gradually improved during their course of recuperation. All stitches were removed on postoperative 2 weeks. Patients are satisfied with the final surgical result and there are no signs of any edema or hematoma. Conclusion: The homodigital reconstruction of finger tip injury using the partial $2^{nd}$ toe pulp flap has numerous advantages compared to other reconstructive modalities such as its resistance to wear and tear and in that it provides a non-slip palmar digital surface. However it requires microsurgery which may not be preferred by surgeons. Advanced age of the patient can be a relative contraindication to this approach since atheromatous plaque from the donor toe can compromise flap circulation after surgery. We report three successful cases which patient age was considered appropriate. Further investigation with a larger number of cases and long term follow-up is deemed necessary.

Isolation and Characterization of Methyl Jasmonate-Inducible Genes in Chinese Cabbage

박용순,조태주 한국통합생물학회 2003 Animal cells and systems Vol.7 No.4

Methyl jasmonate (MeJA) is a signal molecule in the activation of defense responses in plants. In this study, we isolated 15 MeJA-inducible genes by subtractive hybridization. These genes encode two myrosinase-binding proteins, five lipase-like proteins, a polygalacturonase inhibitor, a putative chlorophyll-associated protein, a terpene synthase, a dehydroascorbate reductase, an ascorbate oxidase, a cysteine protease, an O-methyltransferase, and an epithiospecifier protein. Northern analysis showed that most of the Chinese cabbage genes are barely expressed in healthy leaves, but are strongly induced by MeJA treatment. We also examined whether these MeJA-inducible genes were activated by ethethon, BTH, and Pseudomonas syringae pv. tomato (Pst ), a nonhost pathogen of Chinese cabbage. The results showed that none of the MeJA-inducible genes was strongly induced by ethephon or by BTH. The genes encoding lipase-like proteins and a myrosinase-binding protein were weakly induced by Pst. Other MeJA-inducible genes were not activated at all by the pathogen.

Abstract Wife assault is a social problem having existed for all ages and countries of the world, from which the psychological and social damages of the victim are very serious. Among various damages, the learned helplessness is the most representative one. Battered wives having become chronically helpless have lost motivation and coping ability of overcoming the assault. The Purpose of this study is to examine the causes of wife assault and to suggest appropriate intervention plans. These causes are : (1) Psychological factors, (2) family systematic factors, (3) social factors. Based on the above factors, the intervention plans of wife assault are as follows. (1) preventive approach, (2) protective approach. For these purposes, first, fixed sex-role should be eliminated from every aspect of society. second, equal job opportunities should be provided for women regardless of marriage. third, all the laws which discriminated against women should be revised, and attitudes of the administrators should be changed.

Poly(aspartic acid)를 이용한 조직공학용 지지체의 제조 및 특성

박용순 광주보건대학 2004 論文集 Vol.29 No.-

One of the most important properties of synthetic materials for biomedical applictions is that the materials should have biostability, biocompatibility and biodegadability. Polypeptides which were made of amino acid is useful to biomedical application because they are structural materials of biosystem. Poly(aspartic acid) (PAsp) is synthesized by polymerization of the corresponding N-carboxyamino acid anhydride (NCA)in solution in the presence of suitable catalysts. However, the NCA method have a production problem and a cost disadvantage. Recently, a simple method that the high molecular weight PAsp was easily synthesized by the polycondensation of L-aspartic acid in the presence of acid catalyst was developed. In this study, PAsp hydrogels have been prepared by the cross-linking reaction of PAsp produced by thermal polycondensation reactions with an acid catalyst. The molecular weight of synthesized PAsp was about 50,000(M_(W), DP = 500). And the PAsp hydrogels were formed when the the amount of cross-linker, i.e., ethylene diamine was above 10 mol%, The water absorption capacity of the PAsp hydrogel in deionized water was measured. The maximum water absorption capacity in deionized water was 1,400%. The PAsp hydrogels formed the interconnected porous stucture(pore size was about 100~200 ㎛) by scanning electron microscopy observation. The cytotoxicity test was carried out on the PAsp hydrogel using the fibroblast cells. After four days the fibroblast cells adhered and spread well on the PAsp hydrogel. Futhermore, the fibroblast cells proliferated well on the PAsp hydrogel compared with the normally cultured cells on the cell culture plate. These results are indicated that the PAsp hydrogels can be used as the scaffold for tissue engineering applications.

심혈관계질환의 위험지표로서Omega-3 Index에 대한 올바른 이해 및 한국인에의 적용

박용순 대한비만학회 2010 The Korean journal of obesity Vol.19 No.1

오메가-3 다가 불포화지방산인 eicosapentaenoic acid(EPA; C20:5)와 docosahexaenoic acid(DHA; C22:6)는 심혈관계질환으로 인한 사망을 예방하는 영양소로 잘 알려져 있다. 최근에는 오메가-3 지방산이 심혈관계질환뿐 아니라 뇌졸중을 예방하는데도 도움이 된다는 연구결과가 보고되고 있으며, 이러한 오메가-3 지방산의 효과는 항부정맥, 항염증, 혈액응고 억제, 지단백질 농도 저하 등과 관련이 있다고 한다. Omega-3 Index는 오메가-3 지방산의 체내 수준을 나타내는 유일한 표준 혈액 검사로 적혈구의 EPA와 DHA 수준을 의미한다. Omega-3 Index는 섭취한 오메가-3 지방산과 비례할 뿐 아니라, 심장근육의 오메가-3 지방산 농도와도 비례함하고, 심혈관계질환의 위험도와 음의 상관관계를 가진다고 알려져 심혈관계질환의 위험지표로 활용되고 있다. 권장섭취량인 1g의 오메가-3 지방산으로 얻을 수 있는 8-10% Omega-3 Index가 심혈관계질환의 예방을 위한 적정 목표치로 설정되었다. 한국인에게도 Omega-3 Index는 활용가능하나 목표치는 상향 조정이 필요하다고 사료된다. Of all known dietary factors, long-chain omega-3 fatty acids (eicosapentaenoic acid and docosahexaenoic acid) may be the most protective against death from cardiovascular disease. Evidence continues to accrue for benefits of omega-3 fatty acids in the prevention of coronary heart disease and stroke. Anti-arrhythmogenic, anti-inflammatory, anti-thrombotic and hypolipidemic effects of omega-3-fatty acids are emerging as the most likely explanation. New evidence has confirmed and refined the cardioprotective risk factor of Omega-3 Index, the only standardized blood test of omega-3 fatty acids measuring content of erythrocyte eicosapentaenoic and docosahexaenoic acids. Current evidence suggests that individuals with coronary artery disease may reduce their risk of sudden cardiac death by increasing their intake of long-chain omega-3 fatty acids by approximately 1 g per day and achieving a target range of 8-10% Omega-3 Index. However, target range of Omega-3 Index for Koreans may be higher than 10%.
