Description

민물김 추출물을 유효성분으로 포함하는 상처 치료용 조성물 {A composition comprising extract of Prasiola japonica for wound healing}A composition comprising extract of Prasiola japonica for wound healing comprising freshwater laver extract as an active ingredient

본 발명은 민물김 추출물을 유효성분으로 포함하는 상처 치료용 조성물에 관한 것이다.The present invention relates to a composition for wound treatment comprising a freshwater laver extract as an active ingredient.

신체를 외부 침입자로부터 지키고 수분과 체온을 유지하는 피부 조직이 손상된 것이 상처(wound)이며, 상처 치료(wound healing)는 손상된 조직의 기능과 형태적 특성을 다시 정상화시키기 위한 필수적인 반응이다(Woodley, D. T. et al., J. Am. Acad. Dermatol., 12(2Pt2), 420-433, 1985; Orgill, D. et al., CRC, 2009). 상처가 났을 때 적절히 치료되지 않으면 세균 감염 등으로 체내 장기에 치명적인 손상을 일으킬 수도 있으므로, 상처 발생시 손상된 피부 부위가 가능한 한 빨리, 또 본래 피부 구조와 유사하게 복원되도록 조취를 취하는 것이 중요하다.The wound is the damaged skin tissue that protects the body from external intruders and maintains moisture and body temperature, and wound healing is an essential reaction to normalize the function and morphological characteristics of the damaged tissue again (Woodley, DT et al., J. Am. Acad. Dermatol., 12(2Pt2), 420-433, 1985; Orgill, D. et al., CRC, 2009). If the wound is not properly treated, it may cause fatal damage to the organs of the body due to bacterial infection, etc., so it is important to take steps to restore the damaged skin area as soon as possible and similar to the original skin structure when a wound occurs.

상처 치료는 지혈(hemostasis)과 염증기(inflammation)의 1단계, 증식기(proliferation)의 2단계 및 성숙기(remodeling)의 3단계로 이루어지며 각 단계는 중첩되어 연속적으로 진행된다(Bello, Y. M. et al., JAMA, 283(6), 716-718, 2000; Midwood, K. S. et al., Int. J. Biochem. Cell Biol., 36(6), 1031-1037, 2004; Stadelmann, W. K. et al., Am. J. Surg., 176(24A Suppl), 26S-38S, 1998). Wound treatment consists of one stage of hemostasis and inflammation, two stages of proliferation, and three stages of remodeling, and each stage overlaps and proceeds continuously (Bello, YM et al. , JAMA, 283(6), 716-718, 2000; Midwood, KS et al., Int. J. Biochem. Cell Biol., 36(6), 1031-1037, 2004; Stadelmann, WK et al., Am. J. Surg., 176 (24A Suppl), 26S-38S, 1998).

상처가 나면 첫 번째 단계인 지혈과 염증 반응이 일어나는데, 지혈은 수분 내에 혈소판이 상처부위로 집합하여 섬유소성 응고(fibrin clot)를 형성하는 반응으로 출혈을 막는 역할을 한다(Midwood, K. S. et al., Int. J. Biochem. Cell Biol., 36(6), 1031-1037, 2004; Sandeman, S. R. et al., Mech. Ageing Dev., 119(3), 149-157, 2000). 염증 반응은 박테리아나 조직 잔해들이 식균작용(phagocytosis)에 의해 제거되면서 마크로파지(macrophage)로부터 여러 사이토카인(cytokine)들이 방출되어 증식기에 분화(differentiation)되는 세포의 이주(migration)와 분열(mitosis)을 돕게 된다. When a wound is injured, the first step, hemostasis and inflammatory reactions, occur. Hemostasis plays a role in preventing bleeding by forming fibrin clot by collecting platelets within a few minutes (Midwood, KS et al. , Int. J. Biochem. Cell Biol., 36(6), 1031-1037, 2004; Sandeman, SR et al., Mech.Aging Dev., 119(3), 149-157, 2000). Inflammatory response is when bacteria or tissue debris are removed by phagocytosis, and various cytokines are released from macrophages, which causes the migration and mitosis of cells to differentiate during the proliferative phase. Will help.

두 번째 단계인 증식기에는 신생혈관형성, 콜라겐 축적, 육아조직(granulation tissue) 형성, 상피화(epithelialization), 상처 수축 등이 일어난다(Midwood, K. S. et al., Int. J. Biochem. Cell Biol., 36(6), 1031-1037, 2004; Chang, H. Y. et al., PLOS Biol., 2(2), E7, 2004). 이 시기는 상처 유합과 교원질 섬유(collagenous fiber)의 재배열을 위한 초기 단계로서, 섬유아세포(fibroblast)들이 상처 부위에 출현하게 된다(Byl, N. N. et al., Arch. Phys. Med. Rehabil., 73(7), 656-664, 1992). In the second stage, the proliferative phase, angiogenesis, collagen accumulation, granulation tissue formation, epithelialization, wound contraction, etc. occur (Midwood, KS et al., Int. J. Biochem. Cell Biol., 36 (6), 1031-1037, 2004; Chang, HY et al., PLOS Biol., 2(2), E7, 2004). This period is an early stage for wound fusion and rearrangement of collagen fibers, and fibroblasts appear at the wound site (Byl, NN et al., Arch. Phys. Med. Rehabil., 73(7), 656-664, 1992).

최종적으로 성숙기에는 상처의 공간이 육아 조직(granulation tissue)으로 완전히 대체되고 혈관 생성이 최고조에 달하며 교원섬유의 양이 풍부해져 상피세포가 점점 정상 두께를 회복하고 상처 치료가 완료된다(Galeano, M. et al., Wound Repair Regen., 16(2), 208-217, 2008; Garg, H. G. et al., Informa Healthcare, 2000; 박은교, 중앙대학교 대학원 석사학위논문, 2011). Finally, in the maturity stage, the space of the wound is completely replaced by granulation tissue, blood vessel generation reaches its peak, and the amount of collagen fibers becomes abundant, so that the epithelial cells gradually recover their normal thickness and the wound healing is completed (Galeano, M. et al., Wound Repair Regen., 16(2), 208-217, 2008; Garg, HG et al., Informa Healthcare, 2000; Eun-gyo Park, Master's thesis, Chung-Ang University Graduate School, 2011).

표피성장인자(epidermal growth factor, EGF)는 표피성장인자수용체(epidermal growth factor receptor, EGFR)에 결합하여 다양한 세포의 증식, 분화 및 생존을 조절하는 성장인자 중 하나이다. 특히, 각질세포의 증식과 세포이동을 촉진하여 재상피화에 주요한 역할을 담당함으로써, 상처치료에 탁월한 기능을 수행하는 것으로 알려져 있다. 표피성장인자는 혈소판, 대식세포, 섬유모세포 등에서 분비되며 각질세포에는 주변분비(paracrine) 형식으로 작용한다. 표피성장인자는 케라틴 6(K6)과 케라틴 16(K16)의 발현을 증가시키며, 세포증식 신호전달과정을 활성화한다. 임상적으로 조직이식부위, 당뇨성 족부궤양과 같은 만성 창상에 외용 표피성장인자를 도포할 경우 상피화가 촉진되어 상처회복 속도가 단축되는 것으로 알려져 있다(Barrientos, S. et al., Wound Repair Regen., 16(5), 585-601, 2008).Epidermal growth factor (EGF) is one of the growth factors that regulate the proliferation, differentiation, and survival of various cells by binding to the epidermal growth factor receptor (EGFR). In particular, it is known to play a major role in re-epithelialization by promoting keratinocyte proliferation and cell migration, thereby performing an excellent function in wound healing. Epidermal growth factor is secreted from platelets, macrophages, fibroblasts, etc., and acts in the form of paracrine on keratinocytes. Epidermal growth factor increases the expression of keratin 6 (K6) and keratin 16 (K16) and activates the cell proliferation signaling process. Clinically, it is known that application of external epidermal growth factor to chronic wounds such as tissue transplant sites and diabetic foot ulcers accelerates epithelialization and shortens the wound recovery rate (Barrientos, S. et al., Wound Repair Regen. , 16(5), 585-601, 2008).

민물김(Prasiola japonica)은 물김이라는 이름으로 구전되어 왔으며, 현대에 이르러 민물김으로 알려지고 있다. 민물김은 홍조류인 바다김과 달리 녹조류(Green algae, Phylum Chlorophyta)로서 바다가 아닌 민물에서 생육하며, 민물파래과(Prasiolacease)에 포함된다(Park, M. K. et al., J. Plant Bio., 13, 1-10, 1970). 일본에서는 민물김을 카와노리(하천김)라는 이름으로 부르고 있으며, 하천김과 같은 민물 조류를 인공배양하여 높은 상업적 이윤을 창출하고 있다. 우리나라 민물김은 1938년 일본 학자인 Okada가 함경남도 문천군 문천면에서 최초로 채취하여 Prasiola formosana var. coreana Okada로 명명하여 발표한 것이 효시이며(Okada, Y., J. Jpn. Bot., 15, 449-452, 1939), 삼척군의 집단에 대한 형태 및 생태학적 연구가 수행된 바가 있다(Park, M. K. et al., J. Plant Bio., 13, 1-10, 1970). 우리나라에서는 산업화에 따른 인위적 영향으로 40여년 전에 이미 사라진 종으로 알려졌으나 아직 강원도 삼척시의 소한천에 민물김이 분포하고 있음이 밝혀졌다. Freshwater laver ( Prasiola japonica ) has been oral tradition under the name water laver, and is known as freshwater laver in modern times. Freshwater laver, unlike sea laver, which is a red algae, is a green algae (Phylum Chlorophyta), which grows in freshwater, not in the sea, and is included in the Prasiolacease (Park, MK et al., J. Plant Bio., 13, 1-10, 1970). In Japan, freshwater laver is called kawanori (river laver), and freshwater algae such as river laver are artificially cultured to generate high commercial profits. Freshwater laver in Korea was first collected in Muncheon-myeon, Muncheon-gun, Hamgyeongnam-do by Japanese scholar Okada in 1938, and Prasiola formosana var. It was published under the name of coreana Okada (Okada, Y., J. Jpn. Bot., 15, 449-452, 1939), and morphological and ecological studies of the Samcheok-gun group have been conducted (Park, MK et al., J. Plant Bio., 13, 1-10, 1970). In Korea, it was known as a species that had already disappeared 40 years ago due to the artificial influence of industrialization, but it was revealed that freshwater laver is still distributed in Sohancheon in Samcheok-si, Gangwon-do.

민물김과 같은 녹조류 유래 추출물이 항고혈압 및 미코스포린-유사 아미노산(mycosporine-like amino acids, MAAs)에 의한 자외선 차단 등의 활성을 가지는 것으로 보고되었다(Cha, S. H. et al., J. Korean Soc. Food Sci. Nutr., 35, 307-314, 2006; Groniger, A. et al., J. Photochem. Photobiol. B., 66, 54-59, 2002). 한편 일본에서 민물유래 식용김으로 사용하고 있는 스이젠지노리(Suizenzinori, Aphanothece sacrum)에는 고 함량의 철분 및 칼슘 등 미네랄 성분이 풍부한 것으로 조사되었으며, 알러지성 피부염을 억제하는 성분인 사크란(Sacran, sulfated polysaccharide)이 함유되어 있어 약리학적 활용도가 높게 평가되고 있다(Ngatu, N. R. et al., Ann. Allergy Asthma Immunol., 108, 117-122, 2012). 그러나, 국내 자생 민물김에 대한 생리활성물질 성분분석 및 약리학적 분석에 대한 연구는 아직까지 많이 이루어지지 않고 있는 실정이다.It has been reported that extracts derived from green algae such as freshwater laver have antihypertension and UV protection by mycosporine-like amino acids (MAAs) (Cha, SH et al., J. Korean Soc. Food Sci. Nutr., 35, 307-314, 2006; Groniger, A. et al., J. Photochem. Photobiol. B., 66, 54-59, 2002). On the other hand, Suizenzinori (Aphanothece sacrum ), which is used as a freshwater-derived laver in Japan, was found to be rich in minerals such as high iron content and calcium. ), and thus its pharmacological utility is highly evaluated (Ngatu, NR et al., Ann. Allergy Asthma Immunol., 108, 117-122, 2012). However, studies on the analysis of physiologically active substances and pharmacological analysis of domestically grown freshwater laver have not been conducted much.

Health & Environ., 25, 52-62, 2014]에는 민물김 추출물의 생리활성(항암 효과, 항염증 효과, 항산화 효과, 항당뇨 효과, 자외선 차단효과)이 개시되었으며, 한국등록특허 제10-1591401호에는 민물김 추출물의 항암용 약학 조성물이 개시되었고, 한국등록특허 제10-1725758호에는 해조류 추출물을 포함하는 상처 치료 및 피부 재생용 조성물이 개시된 바 있다. 그러나, 민물김 추출물의 상처 치료 효과를 언급한 이전 보고는 아직 없다. As a prior literature related to a composition for treating wounds containing freshwater laver extract, prior literature [Seo, D. W. et al., J. Biomed. Res., 14(2), 83-90, 2013] and [Sa, J. H. et al., Rep. Inst. Health & Environ., 25, 52-62, 2014] discloses the physiological activities of freshwater laver extract (anti-cancer effect, anti-inflammatory effect, antioxidant effect, anti-diabetic effect, UV blocking effect), and Korean Patent No. 10-1591401 No. 1 discloses a pharmaceutical composition for anticancer of a freshwater laver extract, and Korean Patent No. 10-1725758 discloses a composition for wound treatment and skin regeneration including seaweed extract. However, there are no previous reports mentioning the wound healing effect of freshwater laver extract.
