The Recognition and Comparison of Prolan and Prolan-like Substances
The synergism phenomenon has made possible the recognition of substances, which we have called "prolan-like," in a wide variety of conditions. Indeed, it has been possible to demonstrate a prolan-like material in the urine of normal men. The method has shown a wide distribution of prolan-like substances in sera and urines of non-primates without demonstrating, however, significant difference in...
متن کاملFurther Studies on the Hypophyseal Substance Giving Increased Gonadotropic Effects When Combined with Prolan
The hypophyseal substance-the synergic factor-which gives increased gonadotropic effects when combined with prolan has been shown to itself possess a definite though slight gonadotropic activity. It produces transitory follicular enlargement within 24-48 hours, which, however, regresses at once on cessation of treatment so that by the end of the 4th day the ovary again approximates its infantil...
متن کاملDoes the Gonadotropic Hormone Induce Antibodies or Antihormones?
1. It is shown in 52 experiments upon rabbits that the purified gonadotropic hormone has no antigenic function-as an antigen or a haptene-either in the form of prolan derived from the urine of pregnant women or in the form of prosylan, derived from the blood of pregnant mares. 2. The experiments reported elsewhere which ascribe an antigenic structure to prolan, are due to confusion with the so ...
متن کاملThe Action of Cysteine or Cyanide upon Gonadotropic Extracts
Fraenkel-Conrat, Simpson, and Evans (1) have recently reported that hypophyseal gonadotropic hormones may be completely inactivated by cysteine in mildly alkaline solution, whereas prolan, the principle from human pregnancy urine, shows no loss of potency under the same conditions; they have concluded that the disulfide bonds are essential for the activity of the hormones of pituitary origin an...

متن کاملTHE EFFECT O F THE ANTERIOR PITUITARY HORbiONES ON THE GROWTH O F MOUSE SARCOMA
It has been suggested by H. Zondek, B. Zondek, and Hartoch (1) that the so-called ovarian follicle ripening component of the anterior pituitary hormone (Prolan A) may act to hinder tissue growth in general, and particularly the growth of tumors. To test this hypothesis, these authors carried out a series of experiments in which anterior pituitary hormone containing a mixture of both the follicl...
