1	The Response of White Mice to Pituitary Gonadotropins of Fish Doggett, Virginia Clair 08 1900 (has links) The purpose of this experiment is to determine if immature female white mice will react to the gonadotropic hormone from the anterior pituitary of several species of fish. If they can be shown to do so, a second purpose is to establish an assay unit for this fish gonadotropin in order that it may be used with predictable results in inducing extra-seasonal spawning for fresh-water conservation practices. gonadotropic hormone fish mice pituitary gland Gonadotropin.

2	The Response of Amphibia and Rodents to Fish Gonadotropins Bishop, Jack G. 05 1900 (has links) The purpose of this research is, first, to determine by laboratory methods, that species specificity does not exist in closely allied taxonomic animals; second, to determine a unit of activity for the gonadotropic hormone. For this purpose a quantitative method for determining potency is necessary to ascertain the seasonal production of the gonadotropic factor in fish. A further aim in this investigation is to demonstrate that the diversity of the gonadotropic factor, in relation to phylogenetic variations, is not as ineffectual as previously reported. pituitary gland gonadotropic hormone amphibian rodent fish biology Gonadotropin.
