The danger of commercial ultrasonics
Authors of article published in British Medical Journal, recommend to the future parents to refrain from too frequent and useless ultrasonic researches.
Now the science has no weighty proofs some harmful influence of frequent ultrasonics on a fetation. Nevertheless, authors of the publication warn, that long influence of ultrasonic waves can lead to dangerous rise in temperature of tissues of a germ.
The majority of scientists believe, that irrespective of data available now about possible by-effects of ultrasonics-inspections, they are necessary for applying only in the presence of medical indications, and not earlier than the second trimester of pregnancy.
The ultrasonics spent during the first trimester, are especially dangerous, as at this time there is an intensive migration of the cells forming the central nervous system of a child. It is not excluded, that long influence of ultrasonic waves can break this process.
The experiment spent by the American researchers in last year, has shown, that powerful influence of ultrasound can really influence trajectories of movement of erratic cells in a brain of germs of mice. However, by a recognition of scientists, these changes have not caused some significant behavioural deviations in newborn little mice.
