The severity of the changeswas dependent on the concentrations of quinazolinone, as higher doses created more abnormal embryos(syndactily, scaphocephaly, exocephaly, microcephaly, acrocephaly, abnormal polarity in lower and upperlimbs, deviation of body axis, growth retardation) and placentas. Apparently QPPE acts on organogenesis ona specific phase of the developmental stage by expressing genes regulating mitosis and cell proliferation.}, keywords = {Quinazolinone,Balb/C mice embryos,abnormalities}, url = {https://ijsts.shirazu.ac.ir/article_2729.html}, eprint = {https://ijsts.shirazu.ac.ir/article_2729_4a72f3f5b0f13b93fb29be3e475dbf57.pdf} }
