title: Effects of acrylamide and N,N'-methylene-bis-acrylamide on creatine kinase activity.
abstract: In vitro, both acrylamide and N,N'-methylene-bis-acrylamide inhibited creatine kinase (CK) activity from brain or sciatic nerve with almost the same potency. In vivo, only acrylamide (50 mg/kg b. wt./day, 8 days) caused paralysis of hind limbs and suppressed CK activity in cerebrum, cerebellum, spinal cord and muscle in rats. Bis-acrylamide (50 mg or 100 mg/kg b. wt./day, 8 days) caused no paralysis nor inhibition of CK activity in any tissue examined. Definite inhibition of CK was not found in sciatic nerve from rats given either chemical. The inhibition of CK may play a role in the genesis of toxicity of acrylamide especially in the central nervous system.
