This study demonstrated the potential of using urea and urea fertilizer to neutralize formaldehyde (Fd) in chicken cadavers. Initially, in vitro Fd neutralization with various concentrations of urea solution (US) and urea fertilizer solution (UFS) was conducted; subsequently, 18% US and 27% UFS were selected for infusing into the formalinized chickens. The measurement at 48 hr after infusion showed that both solutions could effectively lower Fd in chicken cadavers to below a permissible exposure limit without affecting cadaveric and histological quality. In addition, neutralizing power of 18% US was approximately 1.3 times that of 27% UFS. This is the first demonstration of neutralizing potential of US and UFS against Fd both in vitro and in vivo.
本研究证明了使用尿素和尿素肥料中和鸡尸体中甲醛（Fd）的潜力。最初，进行了用不同浓度尿素溶液（US）和尿素肥料溶液（UFS）进行体外Fd中和实验；随后，选择18%的US和27%的UFS注入用福尔马林处理过的鸡中。注入后48小时的测量结果表明，两种溶液都能有效将鸡尸体中的Fd降低到允许暴露极限以下，且不影响尸体和组织学质量。此外，18% US的中和能力约为27% UFS的1.3倍。这是首次证明US和UFS在体外和体内对Fd的中和潜力。
