Abstract: A CT value controller includes a storage means, an input means, and a computing means. The storage means stores a function expressing a relative humidity and a CT value regarding a degradation degree of an anticancer agent, an assumed relative humidity, and a CT setting. The input means inputs a measured relative humidity and a measured ozone concentration at a time of degradation treatment of the anticancer agent. The computing means calculates a corrected CT value increment based on a difference between the measured relative humidity and the assumed relative humidity at every input of the relative humidity and the ozone concentration by using the function. The computing means determines a termination of the degradation treatment of the anticancer agent when an integrated CT value of the corrected CT value increments reaches the CT setting.

Abstract: The invention proposes the photosensitized generation of nitric oxide (NO) from alanosine (3-(hydroxynitrosoamino)-D,L-alanine) by aluminum phthalocyanine tetrasulfonate (AlPcS4). While NO is obtained in nitrogen-saturated solutions, the invention proposes that both NO and peroxynitrite are produced in air-saturated solutions. Enhancement of NO production occurs in the presence of ubiquinone-0. The invention evidence that NO is produced by the photosensitized oxidation of alanosine. Both NO and peroxynitrite are detected during photoirradiation of AlPcS4 in the presence of 2-methyl-2-nitrosopropane (MNP) and hypoxanthine, but not in the absence of hypoxanthine, in air-saturated solutions, where HX is acting as sacrificial electron donor, thus promoting superoxide formation.
