The results show that the single-layered neural tube fails to form and the neural crest cells remain at the lateral regions in the explants with NTDs. However, the patterning of the neural tube is not affected as indicated by the normal expression of the preneural genes.

结果显示神经管闭合缺陷的移植体不能形成单层化的神经管，并且神经晴细胞滞留在侧面区域不能向背侧中线迁移，而对神经前体标记基因的检测显示神经管的背腹图式形成并未受到影响。

The mean retention time in liver and lung was longer and was eliminated more slowly than other organs. It suggested that there was a correspondence relationship between OADHPS and its hepato-protection. After oral administration, 14. 8％ of OADHPS was excreted as protype. It was assumed that 10.0％ of OADHPS was metabolized in vivo whereas 75. 2％ of OADHPS destroyed in gastrointestinal tract.

药物在肝、肺等组织中的平均滞留时间较长，消除相对较慢，这恰好与齐墩果酸具有的较强的保肝作用相呼应。24h尿中原型药物排泄量占给药量的3.21％，结合绝对生物利用度为21.7％，推测被吸收的药物中约14.8％以原型排泄。
