[Essential microelements and gallstones in children].

The article presents a study of particular features of the essential microelements content in the hair, blood, bile and gallstones in infants with cholelithiasis. It was shown that this disease is accompanied by a lack of microelements, which appears as a lack of selenium, imbalance of zinc and accumulation of iron and copper in biological objects. In conjunction with other factors (vegetative dysfunction, comorbidities of the gastrointestinal tract and maldevelopment of the bile-excreting tract), the lack of microelements can promote the formation of gallstones in infants. It is possible to obtain complete information on particular features of microelements changes with the help of simultaneous studies of tissues of the hair, blood, bile and gallstones.
