Medical stone aluminosilicates (feldspars) contained in its chemical composition, KAlSi 3 O 8, NaAlSi 3 O 8, or CaAl 2 Si 2 O 8, MgAl 2 Si 2 O 8 and the like, wherein Silica SiO 2 is a tetrahedron having SiO 4 and has a cubic solid structure. Moreover, in a part of its structure, aluminum is coordinated by an oxygen bridge to have an embedded state structure.
The adsorption of the pigment and the bacteria is considered to be a bond between the (+)-charged nitrogen atom in the dye molecule and the same (+)-charged nitrogen atom in the bacterial protein. In particular, bacteria, the bacteria have an infinite number of -N+, and multiple combinations of SiO- in the maifan stone occur, which is shown to capture the adsorption phenomenon of the bacteria. In addition, due to weathering and dissolution, the feldspar of the stone has become extremely porous. Compared with the general feldspar, the -SiO- atomic group increases very much and exhibits remarkable adsorption.
Atomic group in medical stone {-SiO-••••••-N+-}
{-SiO-••••••-N+-}
Bacterial protein {-SiO-••••••-N+-}
{-SiO-••••••-N+-}
If the stone is ground into a powder, the ion dissolution and adsorption are enhanced. This phenomenon can also be explained and understood by the above hypothesis. That is to say, it can be considered that the radical of -SiO- in the medical stone is bonded to the nitrogen atom by an excessive bonding point, thereby inhibiting the activity of bacteria or the like.
Use medical stone and its powder, water extract, why save time, why can absorb bacteria. In this regard, Professor Ohno of the University of Pharmaceutical Sciences proposed the following doctrine:
