The object of the present invention is to provide a hangover prophylactic and/or therapeutic agent. The present invention provides a hangover prophylactic and/or therapeutic agent comprising ALAs.

Agent for preventing and/or treating veisalgia

The present invention provides an agent for promoting graft survival which can suppress rejection without use of existing immunosuppressants, an organ preservation solution capable of maintaining the freshness of an organ excised from a donor, and the like. An agent for promoting graft survival or an organ preservation solution is prepared, which comprises 5-aminolevulinic acid (ALA) or a derivative thereof, or a salt of ALA or the derivative and an iron compound as active ingredients. Preferable examples of the ALAs can include ALA and various esters such as methyl ester, ethyl ester, propyl ester, butyl ester, and pentyl ester of ALA, and their hydrochlorides, phosphates, and sulfates. Preferable examples of the iron compound can include sodium ferrous citrate.

Enhancer of survival of transplanted organ

An object of the present invention is to provide a preventive and/or therapeutic agent for radiation damage that has a novel mechanism of action and can prevent and alleviate a wide range of symptoms of radiation damage for which no therapeutic measures have been available so far, and moreover, is highly safe to humans. A preventive and/or therapeutic agent for radiation damage comprising a compound represented by the following formula (I) such as 5-aminolevulinic acid (5-ALA) or a salt thereof as an active ingredient can be used to improve the survival rate, improve body weight reduction, and alleviate hematopoietic disorder: (wherein Rrepresents a hydrogen atom or an acyl group; and Rrepresents a hydrogen atom, a linear or branched alkyl group, a cycloalkyl group, an aryl group, or an aralkyl group).

Prophylactic and/or therapeutic agent for radiation damage

A method for ameliorating and/or preventing cancerous anemia includes administering to a subject in need thereof an agent containing 5-aminolevulinic acid (ALA) or a derivative thereof, or a salt thereof. Preferably, these ALAs contain a metal-containing compound, such as sodium ferrous citrate. The above-mentioned ALAs, ALA; various esters such as ALA methylester, ALA ethylester, ALA propylester, ALA butylester, and ALA pentylester; and hydrochlorides, phosphates, and sulfates, and the like of these ALA esters are preferred examples.

Anemia of cancer improving/prophylactic agent

It is to provide a tumor diagnostic agent and a tumor determination method enabling not only determination of the presence or absence of a tumor in a subject, but also determination of whether the tumor is a malignant tumor or a benign tumor, which can be used simply at low cost with reduced side effects and burden. 5-aminolevulinic acid (ALA) or its derivative, or a salt thereof is orally administered at a dose of 5 to 7 mg in terms of ALA per kg of body weight, and a urine sample 4 to 12 hours after the administration is collected. Porphyrins and creatinine in the urine sample are quantitated, and based on the value (nmol/gCre) obtained by dividing the amount of porphyrins by the amount of creatinine, a distinction among an individual without a tumor, an individual with a benign tumor, and an individual with a malignant tumor is determined. The presence or absence of a malignant tumor in a subject can be clearly determined by administering 1 to 3 mg of ALAs in terms of ALA per kg of body weight.

Diagnostic agent for tumor

The present invention provides a sepsis therapeutic drug useful for prophylaxis and treatment of sepsis. A prophylactic agent and/or a therapeutic agent for sepsis containing 5-aminolevulinic acid (5-ALA) or a derivative thereof or a pharmacologically acceptable salt of 5-ALA or the derivative as an active ingredient is prepared. The prophylactic agent and/or the therapeutic agent preferably contains a metal-containing compound such as ferrous sodium citrate in addition to the ALAs. Preferred examples of the ALAs include ALA; various esters of ALA such as methyl, ethyl, propyl, butyl, and pentyl esters; and hydrochlorides, phosphates, sulfates of ALA and the esters.

Prophylactic agent and/or therapeutic agent for sepsis

A method for ameliorating and/or preventing chronic kidney disease includes administering to a subject in need thereof an agent containing 5-aminolevulinic acid (ALA) or a derivative thereof, or a salt thereof as an active ingredient. Preferably, these ALAs contain a metal-containing compound, such as sodium ferrous citrate. The above-mentioned ALAs, ALA; various esters, such as ALA methylester, ALA ethylester, ALA propylester, ALA butylester, and ALA pentylester; and hydrochlorides, phosphates, and sulfates, and the like of these ALA esters are preferred examples.

Prophylactic agent for chronic kidney disease

An object of the present invention is to provide a regulatory dendritic cell inducing agent applicable to the treatment of immune disease as well as an immune tolerance inducing agent such as a preventive and/or therapeutic agent for allergic disease and a preventive and/or therapeutic agent for autoimmune disease, both of which are safe and have the mechanism of action different from that of conventional drugs. As a means for achieving the above object, an immune tolerance inducing agent comprising 5-aminolevulinic acid (ALA) or a derivative thereof, or a salt of the 5-ALA or the derivative and an iron compound as active ingredients is prepared. Preferable examples of the ALAs can include ALA and various esters such as methyl ester, ethyl ester, propyl ester, butyl ester, and pentyl ester of ALA, and their hydrochlorides, phosphates, and sulfates. Preferable examples of the iron compound can include sodium ferrous citrate.

Immune tolerance inducer

Provided is an enhancer for cancer thermotherapy not combined with photodynamic therapy. Cancer treatment not combined with photodynamic therapy is made available by using, as an enhancer for cancer thermotherapy, 5-aminolevulinic acids represented by formula (1):RRNCHCOCHCHCOR&#x2003;&#x2003;(1)[wherein Rand Reach independently represent a hydrogen atom, an alkyl group, an acyl group, an alkoxycarbonyl group, an aryl group, or an aralkyl group; and Rrepresents a hydroxy group, an alkoxy group, an acyloxy group, an alkoxycarbonyloxy group, an aryloxy group, an aralkyloxy group, or an amino group] or a salt thereof.

Cancer heat therapy-enhancing agent

The present invention relates to an immunosuppressing method which comprises administering a spergualin-related compound represented by the following formula ##STR1## (wherein R.sub.1 is --(CH.sub.2).sub.4 --, --(CH.sub.2).sub.6 --, ##STR2## R.sub.2 is --(CH.sub.2).sub.2 -- or --CH.dbd.CH--; and R.sub.3 is ##STR3## or pharmacologically acceptable salts thereof in an effective amount to a warm-blood animal.

Immunosuppressing method

This invention relates to method for suppressing a transplantation immunity and treating an allergic disease and an autoimmune disease in a mammal which comprises administering spergualin or a pharmaceutically acceptable salt thereof in effective amount to the said mammal.
