ABSTRACT
The following facts are demonstrated:
- The inhibitory influence of cholesterol on hæmolysis and its activation by lecithin, also the presence of a thermolabile ferment in serum which activates hæmolysis, and which appears to vary directly with the blood cholesterol content.
- The influence of cholesterol as a controlling factor in oxidative processes, its controlling power being best exercised in relation to lecithin in the ratio to that substance normally existing in blood.
- That lecithin has an attractive influence on potassium ions, and that the presence of cholesterol in the membrane definitely retards diffusion of potassium.
- The retarding effect of cholesterol on the anionic movement of colloidal lecithin.
- That increase of protein diet has no effect in stimulating metabolism in dementia præcox.
- That the blood-cholesterol content in dementia præcox is greatly diminished, while abnormal increase is noted in states of mania.
- That in general paralysis there is great diminution of cholesterol in the brain substance.
