  • (17) We conclude: 1) ANP is present in the fetus shortly after the completion of organogenesis; 2) 16 K ANP is the principal intracardiac species in the fetus and the adult; and 3) the existence of ANP soon after cardiac development suggests a possible role for ANP in fetal blood pressure and sodium and water homeostasis.

Organogenic


Definition:

  • (a.) Of or pertaining to organogenesis.

Example Sentences:

  • (1) Unlike previous studies with 13-cis-retinoic acid during the pre- and early organogenic stages of development (Hummler et al., Teratology 42:263-272, 1990), no thymic hypo- or aplasia or heart anomalies were observed, which may be attributable to the slightly longer 13-cis retinoic acid treatment period, i.e., GD 10-27.
  • (2) Fischer 344 rats were exposed acutely to 2,3,4,7,8-pentachlorodibenzofuran (4-PeCDF) during the organogenic period to evaluate its potential as an inducer of teratogenic and embryolethal effects.
  • (3) Our research used 40 animals, fed Lieber and DeCarli liquid diets, distributed into 4 groups: C, or control--non-alcoholic--, ad libitum; E, or alcoholic, fed ad libitum; F, or alcoholic, pair fed to E; and P, non-alcoholic, pair fed to E and F. Fetuses of group E were exposed to ethanol during the organogenic period, while those from group F exposed only during the last stage of pregnancy.
  • (4) The questionnaire is computer scored and, based on an interactional model, differentiates between organogenic and psychogenic causes for erectile dysfunction.
  • (5) There is no evidence that this is a peculiarly sensitive stage of development with respect to alcohol; animal studies indicate that other processes in the organogenic period are equally or more vulnerable.
