Abstract

The present invention provides: a heat generation method that makes the first use of the ionic vacancies that are a by-product of an electrochemical reaction and have conventionally been left unreacted; and a device for implementing the same. The present invention pertains to: a heat generation method characterized by comprising colliding, in an electrochemical reaction that proceeds in an electrolysis cell, ionic vacancies having a positive charge generated at an anode and ionic vacancies having a negative charge generated at a cathode; and a heat generation device characterized by being equipped with an electrolysis cell provided with an anode and a cathode and an electrolyte solution accommodated within the electrolysis cell, and by generating heat by colliding ionic vacancies of opposite signs generated by causing the electrochemical reaction to proceed in the electrolysis cell via the anode and the cathode.

Abstract

It is now found that a tissue-accumulating chitosan gel has an anti-tumor activity. Based on this finding, an anti-tumor composition is provided, which comprises a tissue accumulating chitosan gel. Preferably, the tissue-accumulating chitosan gel is a chitosan gel which is mainly composed of a chitosan derivative having a sugar chain introduced therein and is produced by the introducing a optically reactive group into the chitosan derivative and then photocrosslinking the resulting chitosan derivative. Alternatively, the tissue-accumulating chitosan gel is preferably a chitosan gel comprising a polyion complex composed of a chitosan derivative having a sugar chain introduced therein and other substance such as an acidic polysaccharide. The anti-tumor composition can inhibit the expansion of a tissue when merely placed in proximity to the tissue, without being contacted with the tissue.
