[Morphological features of placenta and expression of collagen-6, MMP-1 and TIMP-1 in placental membranes of women with premature rupture of membranes].

Morphological and immunohistochemical investigation of the women's afterbirth with premature rupture of membranes (PROM) and well-time ruptures of placental membranes has been carried out. Inflammatory infiltration of membranes and placental deficiency were higher at patients with PROM. The absence of inflammatory changes in placental tissue during growth of anhydrous gap was demonstrated.
