The present invention has found that chimeric animals suffer from noticeable inflammation after birth, though neither immune response nor inflammation in the fetal period of these animals has been reported hitherto. This is an unexpected finding since chimeric animals in the fetal period were exclusively analyzed in prior studies and thus it is deemed that immunotolerance has been theoretically established therein. The present invention provides a composition for suppressing immune response or inflammation in the fetal period of a born chimeric animal.

An object of the invention is to remove effectively metallic contaminants adhering to the glass substrate surfaces without increasing roughness of the glass substrate surfaces in the glass substrate for a magnetic disk. In a manufacturing method of a glass substrate for a magnetic disk having a cleaning step of the glass substrate, the cleaning step comprising a cleaning treatment of contacting the glass substrate with an alkaline aqueous solution having a gluconate in concentration of not less than 0.05 wt % and not more than 2 wt % added thereto and a pH of not less than 9 and not more than 11 is appended.

An object of the invention is to remove effectively metallic contaminants adhering to the glass substrate surfaces without increasing roughness of the glass substrate surfaces in the glass substrate for a magnetic disk. In a manufacturing method of a glass substrate for a magnetic disk, a cleaning step comprising a treatment of contacting the glass substrate with a cleaning liquid containing peroxodisulfate and having a pH of not less than 2 and not more than 4 is appended. In addition, an example of the cleaning liquid can be prepared by adding sodium peroxodisulfate to an acidic solution.

A method of manufacturing a magnetic disk glass substrate has a cleaning step of cleaning the glass substrate. In the cleaning step, the cleaning is performed under an acidic condition using a cleaning liquid containing oxalate ions and bivalent iron ions. In parallel with the cleaning step or before or after the cleaning step, trivalent iron ions generated by oxidation of the bivalent iron ions contained in the cleaning liquid are reduced by ultraviolet irradiation.
