A carboxylic acid-type lipid can accelerate adhesion or aggregation of platelets even if the carboxylic acid-type lipid does not carry a protein involved in adhesion or aggregation of platelets or a peptide corresponding to an active site of the protein; a lipid particle and a lipid membrane each include the carboxylic acid-type lipid; and a platelet aggregation accelerating agent, a platelet adhesion accelerating agent, a hemostatic agent and a platelet substitute each include the carboxylic acid-type lipid, the lipid particle or the lipid membrane. A carboxylic acid-type lipid is selected from carboxylic acid-type lipids represented by formulas (I) to (VI), a lipid particle includes the carboxylic acid-type lipid, a lipid membrane includes the carboxylic acid-type lipid, and a platelet aggregation accelerating agent, a platelet adhesion accelerating agent, a hemostatic agent and a platelet substitute each include the carboxylic acid-type lipid, the lipid particle or the lipid membrane.

A polymer film can be adjusted to movement or a fine uneven surface of a living body and has excellent ability to adhere to a biological tissue. The polymer film includes a block copolymer having a structure in which branched polyalkylene glycol and polyhydroxyalkanoic acid are bound to each other, wherein the polymer film has a film thickness of 10 to 1000 nm. The branched polyalkylene glycol has at least three terminal hydroxyl groups per molecule, the mass percentage of the branched polyalkylene glycol relative to the total mass of the block copolymer is 1% to 30%, and a value obtained by dividing the average molecular weight of polyhydroxyalkanoic acid in the block copolymer by X that is the number of terminal hydroxyl groups present per a single molecule of the branched polyalkylene glycol is 10000 to 30000.

Provided are a heat exchanger that does not impede downsizing and removes water in the heat absorbing pipe adequately with a simple configuration even when the reduction in diameter of the heat absorbing pipe is made. A heat exchangerin which heat absorbing pipesare disposed in a multi-tier arrangement within a casingwhich is the passage of combustion exhaust gas, both pipe endsof each of the heat absorbing pipesare connected respectively to two headersprovided on a side plateof the casingand water introduced from an external pipeto each of the heat absorbing pipesthrough the headeris heat-exchanged and heated by combustion exhaust gas. The pipe endsof the heat absorbing pipesare arranged at a predetermined vertical interval. A drainage platefor forming a drainage passage through which the water that has reached the pipe end openingsA of respective heat absorbing pipesis removed during drainage operation for the heat absorbing pipesis disposed in the headerdisposed on a lower side of the heat absorbing pipesso as to face a number of the pipe end openingsA vertically arranged in a state of continuous.
