The Response of Amphibia and Rodents to Fish Gonadotropins

The Response of Amphibia and Rodents to Fish Gonadotropins

Date: 1949
Creator: Bishop, Jack G.
Description: 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.

A Quantitative and Qualitative Bacterial Analysis of Pecan Creek

A Quantitative and Qualitative Bacterial Analysis of Pecan Creek

Date: 1946
Creator: Cook, Vernice
Description: Since Pecan Creek receives sewage wastes from an obviously inadequate disposal system, it seemed possible that it could receive pathogenic bacteria. The fact that these might be present in numbers sufficient to cause epidemics, provided the proper natural vectors were present, stimulated an interest in and the pursuance of this study.

The Response of White Mice to Pituitary Gonadotropins of Fish

The Response of White Mice to Pituitary Gonadotropins of Fish

Date: 1949
Creator: Doggett, Virginia Clair
Description: 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.
