| pubmed-article:6696985 | pubmed:abstractText | The authors studied the properties of peripheral blood lymphocyte chromatin from donors (non-pregnant women), from women with normal pregnancy and during threatened abortion. Using three independent cytochemical methods that characterize the DNA accessibility for acridine orange and 3H-actinomycin D and the presence in histones of free amino groups, it has been established that lymphocyte chromatin from women during threatened abortion is repressed to a greater degree than in those with normal pregnancy. The data presented demonstrate the prospectiveness of the use of the cytochemical tests for chromatin properties with a purpose of diagnosing whether the pregnancy will be full-term and treatment control. | lld:pubmed |
