Colorimetric method for the estimation of norethynodrel in tablets containing mestranol
, 1964 The colour method proposed for the estimation of norethynodrel in tablets with mestranol utilises a reaction similar to the well known Zimmerman reaction, the reagents employed being m-dinitrobenzene and benzyltrimethylammonium hydroxide solution and a ...

Tolerance of estrogen-treated rats to acute cold exposure
, 1979 Female rats treated chronically with ethynylestradiol (36 micrograms/kg per day) alone, and in combination with the progestational agent, norethynodrel (253 micrograms/kg per day), cooled significantly faster than controls when lightly restrained and ...

Norethynodrel and chromosome abberrations in Drosophila
, 1967 The synthetic steroid Xorethynodrel was tested for its effect upon ring-shaped X and rod shaped Y chromosomes in Drosonhila melanogaster sperm. The XO method was used to detect breakage of the X and the Y chromosome.
