在体外,丙烯酰胺和丙烯酸均能抑制大鼠脑组织匀浆中肌酸激酶(CK)的活性,且丙烯酸的抑制作用强于丙烯酰胺。然而,在体内,当给药时。大鼠每天50 mg/kg连续8天,仅丙烯酰胺抑制脑内CK活性,并引起明显的神经体征。注射14C标记化合物24小时后,丙烯酰胺组大鼠脑内14C含量是丙烯酸组的7倍以上。丙烯酰胺对8个脑区CK活性的抑制程度不同,从下丘脑的54%到小脑蠕虫的27%。然而,CK抑制的地区差异既不符合14C分布,也不符合临床或病理上易受丙烯酰胺影响的区域的分布。
In vitro, both acrylamide and acrylic acid inhibited creatine kinase (CK) activity in rat brain homogenates, and acrylic acid was more potent than acrylamide. In vivo, however, when given i.p. 50 mg/kg per day for 8 days to rats, only acrylamide inhibited CK activity in the brain and caused apparent neurological signs.14C in the brain 24 h after the injection of14C-labelled chemicals was more than 7 times greater with acrylamide than with acrylic acid. The inhibition of CK activity by acrylamide varied in eight regions of the brain; from 54% in hypothalamus to 27% in cerebellar vermis. The regional difference of CK inhibition, however, did not agree well with either14C distribution or with the distribution in regions which appear clinically or pathologically vulnerable to acrylamide.
