The gonadotropic hormones (ρ-factors)

The Effect of Cysteine on Gonadotropic Hormones*

In the investigation of biologically active substances, major interest attaches to the relation between chemical structure and specific biological activity. One of the best approaches to this problem is given by the study of the effect on biological properties of slight but chemically well defined changes in the molecule. Few methods are available for achieving this in proteins, but fortunately...

Action of Ketene on Gonadotropic Hormones*

Ketene has been found to be a highly specific,acetylating agent for aqueous solution of proteins. It reacts only with amino, thiol, and phenolic hydroxy groups (1). Several investigators (24) have shown that the primary amino groups react most rapidly, while the hydroxy groups of tyrosine are acetylated at a much slower rate. The hydroxy groups in carbohydrate radicals of the protein molecule d...

Pituitary gonadotropic hormones in women with oligo/amenorrhoea.

BACKGROUND Any abnormality of menstrual cycle makes women worried and requires proper evaluation. Oligomenorhea is one of the indicators of Polycystic Disease of the Ovary (PCO) which is associated not only with reproductive failure but it also has metabolic and cardiovascular complications. The recent study was conducted to find out the role of Pituitary Gonadotropins in the diagnosis. After d...

On the Efficacy of the Gonadotropic Hormones in the Treatment of Whooping Cough

The Effects of Gonadotropic Hormones in the Treatment of Experimental Tuberculosis

Experimental tuberculosis in rabbits and guinea pigs was favorably influenced by the administration of antuitrin-S, pregnant mare serum, and, to a lesser extent, follutein. No retardation of disease was obtained by the use of either anterior pituitary extract or emmenin. The results suggest that the gonadotropic hormone may be a factor in the temporary amelioration of symptoms observed in tuber...
