title: Postmortal decay of acetylcholine levels in the spinal cord of rat, chicken and frog.
abstract: The decay of acetylcholine (ACh) after death of an animal has been estimated in the cervical spinal cord of rat, chicken and frog. The level of ACh in the frog (19.90 nmol/g wet weight) shows no variation from 20 to 500 s after death. In the rat and chicken, there is a decrease in the first 100 s after death to lower values; 4.35 nmol/g wet weight in the rat and 4.60 nmol/g wet weight in the chicken. The levels of ACh in the cervical spinal cord of the rat an chicken at the time of death were estimated by extrapolation to time 0 of the curve of the decay of ACh in the first 100 s. The values obtained were: 121.64 nmol/g wet weight in the chicken and 34.19 nmol/g wet weight in the rat.
