Abstract
There was executed an experimental study of the effect of salts of heavy metals (nickel, chromium, lead and zinc) entering the body by peroral route, on the morphology of the skin and its derivatives (hair follicles and sebaceous glands). The experiment was performed on C57BL / 6 mice with the use of the induction of hair follicle cycle by depilation. Under the subacute intoxication with salts of nickel, chromium and lead, there were revealed such signs of a dystrophic anagen as ectopia of granules of melanin in the dermal papilla and perifollicular tissue, enlarged channels of the hair. The duration of the anagen stage if compared with the control did not change. Under the intoxication with salts of nickel and lead there was revealed infiltration by mononuclear dermis and hypodermis. Lead acetate gave rise in the capillary congestion of the dermis, followed by diapedesis of erythrocytes and infiltration of the dermis by siderophages. In the course of the immunohistochemical study of the proliferative activity of keratinocytes of the skin integument derivatives with the use of antibodies to Ki-67, there was revealed a significant increase of proliferative activity of keratinocytes in comparison with the control under the use of a solution of zinc sulphate and sodium dichromate and its decrease with the use of lead acetate solution.
