【 摘 要 】

This study demonstrated the potential of using urea and urea fertilizer to neutralizeformaldehyde (Fd) in chicken cadavers. Initially, in vitro Fdneutralization with various concentrations of urea solution (US) and urea fertilizersolution (UFS) was conducted; subsequently, 18% US and 27% UFS were selected for infusinginto the formalinized chickens. The measurement at 48 hr after infusion showed that bothsolutions could effectively lower Fd in chicken cadavers to below a permissible exposurelimit without affecting cadaveric and histological quality. In addition, neutralizingpower of 18% US was approximately 1.3 times that of 27% UFS. This is the firstdemonstration of neutralizing potential of US and UFS against Fd both invitro and in vivo.
