According to Canadian scientists, toxic carbon monoxide, contained in exhaust and tobacco smoke, with time can become a base for a new
generation of medicines against serious complication of pregnancy - late toxicosis or preeclampsia. Symptoms of preeclampsia include abrupt increase in arterial pressure and defect
of kidney work, what is dangerous for mother`s and fetus`s lives.

Mechanism of development of this condition is not completely studied yet, however,
it is considered, that disease of placenta (membrane, providing fetus with oxygen
and nutritive elements) cells causes it. It is known that smoking women suffer
from preeclampsia much rarer. According to scientists, they have solid grounds
to suppose that this effect is connected with carbon monoxide influence, inhaled
by smokers together with tobacco smoke in rather big quantities. To check this
hypothesis, researchers tested influence of carbon monoxide on human mature placenta
cells and compared them with cells, not affected by carbon monoxide.

According to their data, carbon monoxide influence reduced speed of cell death
60%. Nowadays scientists received grant for experiments, which could confirm hypothesis
about carbon monoxide wholesome influence clinically. Researchers warn, even in
case tests are successful, therapeutic usage of carbon monoxide is rather far
future business: according to their calculations, at least 4 years are necessary
to start first laboratory experiments on animals.

Up to two years are necessary to prepare clinical tests with participation of
people. The safest (for mother and fetus) method of carbon monoxide delivery to
placenta cells is still unsettled.
