摘要:
A crosslinking reaction and a reaction for reducing molecular weight that take place in a hyaluronic acid-methotrexate conjugate upon irradiation with light are suppressed to improve the photostability of the conjugate. Specifically, a substance having a quenching effect and/or a radical scaveng effect is added to a pharmaceutical composition containing the hyaluronic acid-methotrexate conjugate.

摘要:
A glass substrate has a pair of main surfaces opposite to each other. Two island-shaped portions made of silicon are buried in the glass substrate. The two island-shaped portions are exposed from the two main surfaces of the glass substrate, respectively. An electrode is formed on one main surface of the glass substrate so as to be electrically connected to one exposed portion of one island-shaped portion, and another electrode is formed thereon so as to be electrically connected to one exposed portion of the other island-shaped portion. Still another electrode is formed on the other main surface of the glass substrate so as to be electrically connected to the other exposed portion of the one island-shaped portion. A silicon substrate having a pressure sensing diaphragm is bonded to the other main surface of the glass substrate.
