Description

유착방지제 {A conglutination inhibitor}Adhesion Inhibitor {A conglutination inhibitor}

본 발명은 수술부위의 출혈을 방지하는 효과(지혈효과)와 수술부위의 조직 상호간의 유착을 방지하는 효과(유착효과)가 우수한 유착방지제에 관한 것이다.The present invention relates to an anti-adhesion agent having an excellent effect of preventing bleeding at the surgical site (hemostatic effect) and an effect of preventing adhesion between tissues at the surgical site (adhesion effect).

일반적으로 수술 후나 수술 중에 약간의 출혈이 있는 경우, 수술부위의 봉합이 끝난 뒤에 수술부위 혹은 출혈이 있는 부위와 기존의 세포 조직부분이 접착 되어서 재수술 시에 많은 문제가 발생된다. 특히 복강 수술의 경우는 장기 상호간의 접착(예를 들면 장과 복강벽의 접착)으로 인해 많은 문제가 제기 된다. 이러한 문제를 해결하기 위해서 체내에서 분해가 이루어지면서 유해성이 아주 적은 유착방지제를 사용하여 장기 상호간 접착을 단기 또는 장기간 방지하기 위한 연구가 활발하게 진행되어 왔다.In general, if there is a slight bleeding after surgery or during surgery, the surgical site or the bleeding site and the existing cell tissue portion are bonded after the closure of the surgical site, many problems occur during reoperation. In the case of laparoscopic surgery, many problems arise due to long-term adhesion (for example, adhesion of the intestinal and abdominal wall). In order to solve this problem, studies have been actively conducted to prevent long-term mutual adhesion between long-term mutual adhesion by using an anti-adhesion agent having very low harmfulness as it is decomposed in the body.

유착방지제에는 장기간의 유착을 방지하는 성능 및 출혈을 방지하는 성능 외에도 양호한 점착성, 도포성, 조직과의 친화성, 항균성 등의 특성이 요구되고 있다.In addition to the ability to prevent long-term adhesion and bleeding, the anti-adhesion agent requires properties such as good adhesiveness, applicability, affinity with tissues, and antibacterial properties.

현재까지는 주로 미국 그리에텍(Gliatech)사에서 제조, 시판하는 겔타입의 유착방지제(상품명 : ADCON-L)가 사용되어 왔다. 상기 유착방지제는 인산염(Phosphated saline), 포-신(Porcine) 및 폴리글리칸 에스터(Polyglycan ester) 등으로 구성된다. 한편 미국특허 5,994,325호에서는 펜토산 폴리설파이트(Pentosan Polysulfate)와 단백질과 같은 캐리어로 구성된 유착방지제를 제안하고 있다.Until now, a gel type anti-adhesion agent (trade name: ADCON-L) manufactured and marketed mainly by Gliatech, USA has been used. The anti-adhesion agent is composed of phosphate (Phosphated saline), Po-cine (Porcine) and polyglycan ester (Polyglycan ester). Meanwhile, US Patent 5,994,325 proposes an anti-adhesion agent composed of a carrier such as Pentosan Polysulfate and a protein.

그러나 상기 종래 유착방지제들은 유착방지에 요구되는 유착방지 성능, 지혈성, 점착성, 친화성 등의 여러 특성을 고루 구비하지 못하여 수술부위 간의 유착을 효과적으로 방지 할 수 없는 문제가 있었다.However, the conventional anti-adhesion agents do not have various characteristics such as anti-adhesion performance, hemostaticity, adhesiveness, and affinity required for anti-adhesion, there was a problem in that adhesion between surgical sites could not be effectively prevented.

본 발명은 이와 같은 종래 문제점을 해결하기 위하여 항염증과 항균성을 구비하고 있으며, 상처부위의 재생기능과 지혈효과가 우수한 키토산(Chitosan)을 주성분으로 하여 유착방지성, 지혈성, 점착성, 친화성, 투명도 등과 같이 유착방지제에 요구되는 여러 특성을 고루 구비한 겔 타입의 유착방지제를 제공하고자 한다.The present invention has anti-inflammatory and antimicrobial properties in order to solve such a conventional problem, chitosan (Chitosan) with excellent regeneration function and hemostatic effect of the wound area as the main component anti-adhesion, hemostatic, adhesiveness, affinity, An object of the present invention is to provide a gel type anti-adhesion agent having various characteristics required for the anti-adhesion agent such as transparency.

이와 같은 과제를 달성하기 위한 본 발명의 유착방지제는 키토산 1.0∼5.0중량%, 폴리에틸렌글리콜(PEG) 0∼2.5중량%, 아가로스(Agarose) 0∼8중량%, 항생제 0∼1중량% 및 물 83.5∼99.0중량%로 조성된 것을 특징으로 한다.The anti-adhesion agent of the present invention for achieving this problem is 1.0 to 5.0% by weight of chitosan, 0 to 2.5% by weight of polyethylene glycol (PEG), 0 to 8% by weight of agarose, 0 to 1% by weight of antibiotics and water It is characterized in that it is composed of 83.5 to 99.9% by weight.

이하 본 발명을 상세하게 설명한다.Hereinafter, the present invention will be described in detail.

본 발명의 유착방지제는 키토산을 물에 용해시켜 제조하거나, 주성분인 키토산과 함께 폴리에틸렌글리콜(PEG), 아가로스(Agarose) 및/또는 항생제를 물에 용해시켜 제조한다. 그 결과 본 발명의 유착방지제는 겔 타입이 된다.The anti-adhesion agent of the present invention is prepared by dissolving chitosan in water, or by dissolving polyethylene glycol (PEG), agarose and / or antibiotics in water with chitosan as a main component. As a result, the anti-adhesion agent of the present invention becomes a gel type.

본 발명의 주성분인 키토산(Chitosan)은 항염증성, 항균성, 상처부위 재생성, 지혈성이 우수하며 인체 내에서의 분해시간이 1주일 정도로 비교적 짧다.Chitosan, the main component of the present invention, has excellent anti-inflammatory, antimicrobial, wound regeneration, and hemostatic properties, and has a relatively short disintegration time of 1 week in the human body.

본 발명에서 사용하는 키토산으로는 분자량이 50,000 이하인 수용성 물질을 사용하는 것이 바람직 하다. 수용성이 아니고 아세트산과 같은 약산에 용해되는 키토산일 경우 중화에 많은 시간과 비용이 소모되는 문제가 발생한다.As chitosan used by this invention, it is preferable to use the water-soluble substance whose molecular weight is 50,000 or less. In case of chitosan which is not water-soluble and dissolved in a weak acid such as acetic acid, it takes a lot of time and money to neutralize.

분자량이 25,000인 키토산은 항암 및 항균성이 우수하고, 인체내 분해 시간이 굉장히 빠르고 체내 흡수가 용이한 것으로 알려져 있다. 따라서 본 발명에서도 분자량이 25,000 정도인 키토산을 사용하는 것이 더욱 바람직 하다. 그러나 키토산의 분자량이 너무 낮은 경우 점도가 낮아져 점착성이 저하 될 수 있다. 또한 본 발명에서 사용하는 키토산의 아세틸화는 100%인 것이 바람직 하다.Chitosan having a molecular weight of 25,000 is known to be excellent in anticancer and antibacterial properties, to have a fast decomposition time in the human body and to be easily absorbed in the body. Therefore, in this invention, it is more preferable to use chitosan whose molecular weight is about 25,000. However, if the molecular weight of chitosan is too low, the viscosity may be lowered and the adhesion may be lowered. In addition, the acetylation of chitosan used in the present invention is preferably 100%.

유착방지제 내 키토산의 함량(농도)은 1.0∼5.0중량인 것이 좋으나 수술부위에 따라 키토산의 함량을 적절하게 조절 할 수 있다.The amount (concentration) of chitosan in the anti-adhesion agent is preferably 1.0 to 5.0 weight, but the chitosan content can be properly adjusted according to the surgical site.

키토산의 함량이 너무 높은 경우에는 수술후 장기가 제자리로 돌아가는데 방해를 줄 가능성이 있고, 양분의 흡수 및 통과를 저해 할 수 있기 때문에 바람직 하다. 한편 키토산의 함량이 너무 낮은 경우에는 유착방지 및 지혈효과 등이 저조해지고, 점착성이 저하되는 문제가 발생 될 수 있다.If the content of chitosan is too high, it is preferable because it may interfere with the return of organs after surgery, and may inhibit the absorption and passage of nutrients. On the other hand, if the content of chitosan is too low, such as anti-adhesion and hemostatic effect is lowered, there may be a problem that the adhesion is reduced.

예를들어 외상 또는 출혈이 많은 부분에 사용하는 경우에는 키토산의 함량을 상대적으로 높게 하는 것이 좋고, 내부 장기에 사용하는 경우에는 키토산의 함량을 상대적으로 낮게 하는 것이 좋다.For example, when used in areas where trauma or bleeding is high, the content of chitosan may be relatively high, and when used in internal organs, the content of chitosan may be relatively low.

일반적으로 본 발명의 유착방지제 내 키토산의 함량을 1∼2중량%로 하는 것이 더욱 바람직 하다. 이 경우 유착방지제가 윤활 역할을 하여 장기의 귀향성이 좋았고, 유착방지제의 적절한 점성으로 인해 수술 후 장기 상호간의 유착을 효과적으로 방지 할 수 있다.In general, the content of chitosan in the anti-adhesion agent of the present invention is more preferably 1 to 2% by weight. In this case, the anti-adhesion agent acts as a lubrication, so the return of organs is good, and due to the proper viscosity of the anti-adhesion agent, it is possible to effectively prevent adhesion between organs after surgery.

본 발명의 유착방지제는 윤활성 증진을 위해 폴리에틸렌글리콜(PEG) 2.5중량% 이하를 선택적으로 첨가하여 제조 될 수 있다. 다시 말해 본 발명의 유착방지제 내에 폴리에틸렌글리콜(PEG)이 함유되지 않을 수도 있지만 윤활성 증진을 위해 2.5중량% 이하의 폴리에틸렌글리콜(PEG)이 함유 될 수도 있다.The anti-adhesion agent of the present invention may be prepared by selectively adding 2.5% by weight or less of polyethylene glycol (PEG) to improve lubricity. In other words, polyethylene glycol (PEG) may not be contained in the anti-adhesion agent of the present invention, but may contain 2.5% by weight or less of polyethylene glycol (PEG) to improve lubricity.

이때 사용되는 폴리에틸렌글리콜(PEG)은 인체내에서 분해될 수 있도록 분자량이 10,000 이하인 것이 좋고, 더욱 바람직 하기로는 3,000∼5,000 정도인 것이 좋다. 폴리에틸렌글리콜(PEG)의 분자량이 2,000 이하인 경우에는 액상으로 인체내에서 독성을 일으킬 우려가 있으므로 바람직 하지 않다.The polyethylene glycol (PEG) used at this time is preferably a molecular weight of 10,000 or less, more preferably 3,000 to 5,000 so as to be decomposed in the human body. When the molecular weight of polyethylene glycol (PEG) is 2,000 or less, it is not preferable because the liquid may cause toxicity in the human body.

상기 폴리에틸렌글리콜(PEG)의 함량이 2.5중량%를 초과하는 경우에는 윤활성은 증대되나 점착성이 너무 낮아져 바람직 하지 않다.When the content of the polyethylene glycol (PEG) exceeds 2.5% by weight, the lubricity is increased but the adhesiveness is too low is not preferred.

한편 본 발명의 유착방지제 내에는 항균성, 점착성, 친화성 등의 증진을 위해 항생제 0∼1중량% 및 아가로스(Agarose) 0∼8중량%가 선택적으로 함유 될 수 있다.Meanwhile, in the anti-adhesion agent of the present invention, 0 to 1% by weight of antibiotics and 0 to 8% by weight of agarose (Agarose) may be selectively contained in order to enhance antimicrobial, adhesiveness, affinity, and the like.

이와 같이 제조된 겔 타입의 본 발명 유착방지제는 고온에서 멸균처리 하는 것이 더욱 바람직 하다. 멸균처리 온도는 유착방지제 내에 함유된 폴리에틸렌글리콜(PEG)이 멸균처리로 인해 독성을 일으키지 않도록 150℃ 이하의 온도에서 5∼20분 정도, 더욱 바람직 하기로는 120℃에서 10분 정도 하는 것이 좋다.As described above, the gel-type anti-adhesion agent of the present invention is more preferably sterilized at a high temperature. The sterilization temperature may be about 5 to 20 minutes at a temperature of 150 ° C. or less, more preferably about 10 minutes at 120 ° C. so that polyethylene glycol (PEG) contained in the anti-adhesion agent does not cause toxicity due to sterilization.

본 발명은 항염증, 항균성, 상처부위 재생기능, 지혈효과 등이 우수한 키토산을 주성분으로 하고 있어서, 세포조직 간의 유착방지 및 지혈효과가 우수하다. 아울러 본 발명 폴리에틸렌글리콜, 아가로스 및/또는 항생제를 선택적으로 함유하고 있어서 윤활성, 접착성, 친화성 등도 향상시킬 수 있다. 본 발명의 유착방지제는 비교적 단기간 동안 세포간 유착을 방지하는 용도에 주로 사용한다.The present invention is chitosan excellent in anti-inflammatory, antimicrobial properties, wound regeneration function, hemostatic effect, etc., it is excellent in preventing adhesion between the tissue and hemostatic effect. In addition, the present invention optionally contains polyethylene glycol, agarose and / or antibiotics to improve lubricity, adhesion, affinity, and the like. The anti-adhesion agent of the present invention is mainly used for the purpose of preventing intercellular adhesion for a relatively short time.

이하 실시예 및 비교실시예를 통하여 본 발명을 더욱 구체적으로 살펴본다. 그러나 본 발명이 아래 실시예에만 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples. However, the present invention is not limited only to the following examples.
