title: [Relative concentration of deoxyribonucleic acid in the experimental deciduoma and the blastocyst of female rats: cytophotometric study].
abstract: Polyploidy level of experimentally induced deciduomata was determined by cytophotometric measures of DNA-Feulgen, with the "Ultramikrospektrophotometer UMSP Zeiss" by scanning. The antimesometrial tissue reached 32 n, 72 H after the uterine trauma, whereas the mesometrial part did not exceed a 4 n polyploidy level. With the same technics we studied the ovarian hormone, its action upon the blastocyst cellular cycle. In delayed blastocysts, synthesis was never found. OEstradiol removed the inhibition and DNA synthesis then starts again.
