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.
