Claim 0:
1. A drug for a disease of a kidney, comprising one or more of (a), (b) or (c):
(a) an aggregate of silicon fine particles, the aggregate having a size of more than 0.1 μm;
(b) a crystal grain of silicon, the crystal grain having a particle size of about 1 μm to about 2 μm, and
(c) one or more hydrogen generating material selected from the group of:
porous silicon fine particles having a size of more than 100 nm,
polycrystalline silicon fine particles having a size of more than 100 nm,
unfree silicon fine particles having a size of more than 100 nm,
hardly crushed silicon fine particles having a size of more than 100 nm,
silicon fine particles having a size of more than 100 nm and granulated with an undecomposed binding agent, and
a porous crystal grain of silicon, the porous crystal grain having a size of more than 100 nm,

wherein hydrogen is generated by bringing a water-containing liquid in an intestine into contact with the aggregate of silicon fine particles, the crystal grain of silicon or the one or more hydrogen generating material.
