Chemical Nature of Toxohormone (Nakahara)

Some systemic effects of toxohormone.

Toxic materials released into the blood by tumors may be responsible for the deleterious effects of the tumor upon its host, or the tumor may affect the host by removing essential nutrients from the blood (9). One area of this problem intensively studied has been the effect of the tumor on the liver catalase of the host. The lowered concentration of hepatic catalase, which has been demonstrated...

Chemical nature of remineralized flattened enamel surfaces.

Infrared internal reflection spectroscopy (IRS) was used to investigate chemical changes of enamel surface during in vitro remineralization. Specimens were demineralized and exposed either to calcium phosphate-fluoride solutions or to acidulated fluorophosphate. The former showed amorphous phosphate remineralization, and the latter showed surface precipitate interpreted to be calcium fluoride. ...
