[Placental morphometric characteristics in women who have experienced mono- and mixed viral respiratory infections during pregnancy].

Objective: To study placental morphometric parameters in women who have experienced mono- and mixed viral respiratory infections during pregnancy.

Subject And Methods: Three groups of placentas were studied. Group 1 consisted of 25 placentas from women with physiological pregnancy; Group 2 included 25 placentas from those who had experienced parainfluenza type 3; and Group 3 comprised 25 placentas from those who had mixed respiratory viral infection (parainfluenza type 3 concurrent with influenza A (H3N2)) in the second trimester of pregnancy.
