[challenge] the wound surface, and to the failure of cells, to form a film having a very thin water-repellent and degreasing both characteristics, the wound surface and failure cells coated, of intracellular fluid from the failure cells prevent leakage, by preventing the inflammatory response, and mitigate the spontaneous pain, wound dressing to promote wound healing, and various organs within the outer surface of the cell adhesion-type coating agents, and as asylum agents, suture site, vascular anastomosis, the intestinal edema associated with inflammatory response by laparotomy suppressed, providing a biological coating agent for the purpose of preventing adhesion ileus like. Biological coating agent containing aluminum and cyclodextrin and tannin chloride (tannic acid) and water as A main component. 100 parts of water to aluminum chloride is from 0.01 to 25.0 wt%, cyclodextrin 0.1 to 45% by weight and tannins (tannic acid) is from 0.01 to 50.0 wt%, a biological membrane agent. The main component water, moisture in body fluids biological coating agent is (sweat juice, tears, saliva, blood, gastric juice and so on of the living water).BACKGROUND【課題】創傷面、及び障害性細胞に対し、極めて薄い撥水及び脱脂両特性を有する被膜を形成し、創傷面及び障害性細胞を被覆し、障害性細胞からの細胞内液の漏出を防ぎ、炎症反応を防ぐことにより、自発性疼痛を緩和し、創傷治癒を促進する創傷被覆剤、及び諸臓器内外面の細胞密着型被覆剤、及び庇護剤として、縫合部位、血管吻合、開腹手術による炎症反応に伴う腸管浮腫を抑制し、癒着性イレウス等を防止することを目的とする生体皮膜剤の提供。【解決手段】主剤として塩化アルミニウムとシクロデキストリンとタンニン(タンニン酸)と水とを含む生体皮膜剤。水100部に対し、塩化アルミニウムが0.01~25.0重量%、シクロデキストリンが0.1~45重量%及びタンニン(タンニン酸)が0.01~50.0重量%である、生体皮膜剤。主剤となる水が、体液中の水分(汗汁、涙液、唾液、血液、胃液等々の生体水分)である生体皮膜剤。【選択図】なし
