[DNA concentration in cells of the glandular epithelium of the endometrium during the menstrual bleeding phase]. 1978

S Kh Khakimova, and R N Stepanova, and L S Strochkova

DNA content in the endometrial gland cells (9 women of fertile age) was studied during menstruation by microspectrophotometry. It was shown that DNA content (mainly 2n) remained unchanged during different days of menstruation, both during the desquamation (the 1st--2nd days of the cycle), and during the regeneration stage (the 3rd--4th days). Along with this the mitotic activity in the glandular epithelium was absent completely (36 samples of endometrium).

UI MeSH Term Description Entries
D008598 Menstruation The periodic shedding of the ENDOMETRIUM and associated menstrual bleeding in the MENSTRUAL CYCLE of humans and primates. Menstruation is due to the decline in circulating PROGESTERONE, and occurs at the late LUTEAL PHASE when LUTEOLYSIS of the CORPUS LUTEUM takes place.
D003585 Cell Biology The study of the structure, behavior, growth, reproduction, and pathology of cells; and the function and chemistry of cellular components. Cellular Biology,Biologies, Cell,Biologies, Cellular,Biology, Cell,Biology, Cellular,Cell Biologies,Cellular Biologies
D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine). DNA, Double-Stranded,Deoxyribonucleic Acid,ds-DNA,DNA, Double Stranded,Double-Stranded DNA,ds DNA
D004717 Endometrium The mucous membrane lining of the uterine cavity that is hormonally responsive during the MENSTRUAL CYCLE and PREGNANCY. The endometrium undergoes cyclic changes that characterize MENSTRUATION. After successful FERTILIZATION, it serves to sustain the developing embryo. Endometria
D005260 Female Females
D006651 Histocytochemistry Study of intracellular distribution of chemicals, reaction sites, enzymes, etc., by means of staining reactions, radioactive isotope uptake, selective metal distribution in electron microscopy, or other methods. Cytochemistry
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
