[Effect of contraceptives on the digestibility of dietary protein and nitrogen balance]. 1981

K Gruhn, and A Hennig, and G Klinger, and G Krause

The present paper deals with the effects of the hormonal contraceptives Deposiston and Gravistat on the digestibility of dietary crude protein and on the urine excretion of nitrogen. The substances under test were given to nine women aged between 18 and 25 years. The faecal and the urinary nitrogen were determined in the first two cycles during which no contraceptives were used, and also in the subsequent three cycles during which Deposiston and Gravistat were taken by mouth. The preperiod extended over 3 days; and the sampling period, over 4 days. The apparent digestibility of the dietary protein was but slightly increased by the contraceptives. In case of Deposiston for example, it amounted to 85.0% (1st cycle), 86.0% (2nd cycle), 87.3% (3rd cycle), 87.1% (4th cycle), and 88.2% (5th cycle). Deposiston and Gravistat did not affect the urine excretion of nitrogen and the nitrogen balance.

UI	MeSH Term	Description	Entries
D009584	Nitrogen	An element with the atomic symbol N, atomic number 7, and atomic weight [14.00643; 14.00728]. Nitrogen exists as a diatomic gas and makes up about 78% of the earth's atmosphere by volume. It is a constituent of proteins and nucleic acids and found in all living cells.
D009640	Norethindrone	A synthetic progestational hormone with actions similar to those of PROGESTERONE but functioning as a more potent inhibitor of ovulation. It has weak estrogenic and androgenic properties. The hormone has been used in treating amenorrhea, functional uterine bleeding, endometriosis, and for CONTRACEPTION.	19-Norpregn-4-en-20-yn-3-one, 17-hydroxy-, (17alpha)-,Ethinylnortestosterone,Norethisterone,Norpregneninolone,Conceplan,Micronor,Monogest,Nor-QD,Norcolut,Norcolute,Norethindrone, (1 beta)-Isomer,Norlutin,Nor QD,NorQD
D009644	Norgestrel	A synthetic progestational agent with actions similar to those of PROGESTERONE. This racemic or (+-)-form has about half the potency of the levo form (LEVONORGESTREL). Norgestrel is used as a contraceptive, ovulation inhibitor, and for the control of menstrual disorders and endometriosis.	18,19-Dinorpregn-4-en-20-yn-3-one, 13-ethyl-17-hydroxy-, (17alpha)-(+-)-,DL-Norgestrel,Neogest,Ovrette,Postinor,Wy-3707,DL Norgestrel,Wy 3707,Wy3707
D003276	Contraceptives, Oral	Compounds, usually hormonal, taken orally in order to block ovulation and prevent the occurrence of pregnancy. The hormones are generally estrogen or progesterone or both.
