Acetaldehyde kills Paramecium caudatum in a solution 1:800. 2. Acetaldehyde causes a depression of the central nervous system of vertebrates. Small doses of acetaldehyde stimulate the respiratory center and lower blood pressure, larger ones paralyze the respiration. 3. Larger doses of acetaldehyde stop the secretion of the urine. 4. Acetaldehyde relaxes the smooth muscles of the intestines, vessels, bladder and uterus. 5. Large doses of acetaldehyde depress the irritability and contractibility of the skeletal muscles of the frog. 6. Acetaldehyde in a concentration below 1:1000 is non toxic for the isolated organs of the warm blooded animals.
