Results and discussion

Any other information on results incl. tables

The acid sodium phosphate when intravenously injected in high doses in the rabbits, causes the death of the animal under characteristic tetanus-like contractions. When smaller doses are used the animal dies under a constant depressive syndrome. The minimal lethal dose is equivalent to 1075 g/kg.
