УЛЬТРАЗВУК МОЖЕТ ИЗМЕНЯТЬ ПРОНИЦАЕМОСТЬ ЗАРОДЫШЕВЫХ ОБОЛОЧЕК АМФИБИЙ

Abstract

It was demonstrated that continuous ultrasound modifies the permeability of embryonic envelope of grass
frog Rana temporaria for fluorochromes ANS, FDA and fluorescein. It was found that the ultrasound
of 0,88 MGHz and 0,4-0,7 W/cm2 intensity increased the permeability of embryonic envelope for ANS
and FDA, whereas the ultrasound of 2,64 MGHz and the same intensity increased the permeability for
fluorescein with retention of the low permeability for FDA. Embryos continued the normal development
after treatment with ultrasound under these conditions.
