Antibiocity of the Oleoresins of One Hundred Texas Spermatophytes upon Twenty Gram-Positive Bacterial Organisms

Description: This investigation is concerned with the testing, in vitro, of oleoresins from one hundred higher plants common to North and South Central Texas. The plants used were selected in order to obtain a representative collection which might be of value in future research.

A Comparative Study of Egg Media in the Primary Isolation of Mycobacterium Tuberculosis

Description: The primary purpose of this investigation is not only to improve the present technique of culture of Mycobacterium tuberculosis, but also to make a comparative study of the media use, namely, Veterans Administration modification of Trudeau's medium, Lowenstein's egg medium, and that developed by the author, in order to find which, if any, of these will most easily and effectively meet the needs of the hospital laboratory.

The Fecundity of the Bluegill (Lepomis Macrochirus) in Certain Small East Texas Reservoirs

Description: A study of reproduction and spawning habits of the bluegill in a particular lake must include adequate samples for each period of the year. This will make it possible to determine the number of eggs in each spawn and the frequency of spawning. The number of spawns and average egg production for various sized fish shows the pattern of activity and makes possible further basic research.

The Histological Effects of Injections of Fish Pituitary Extracts on the Testes of Male Frogs, (Rana Pipiens), and the Reproductive System of Immature Mice

Description: The purpose of this investigation was first, to make a histological and cytological study of the testis of male frogs, Rana pipiens, and to determine if there were tissue or cellular changes as well as physiological effects caused by fish pituitary-extract injections. Second, to determine if injections of fish pituitary extract into immature female white mice caused histological changes in the ovaries and uteri.

Microflora Found in a Selected Group of Food Products Enclosed in a Protective Wrapper

Description: The purposes of this study are, first, to determine relative numbers and predominant types of bacterial organisms in the various food products studied; second, to evaluate the efficiency of the paper coverings of these foods; and third, to determine whether these products are potential sources of food poisoning.

The Response of Amphibia and Rodents to Fish Gonadotropins

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 phylogeneti… more

The Response of White Mice to Pituitary Gonadotropins of Fish

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.

Seasonal Survey of Actinomycetes in Twenty Denton County, Texas, Soils

Description: This investigation has had for its aim a further study of actinomycete flora of twenty Denton County, Texas, soils. The problem has evolved itself into, first, a seasonal analysis for the number of actinomycetes in each of the twenty soils; second, a determination of the types of soils that contain the greatest number of actinomycetes in each cultivated and uncultivated land; third, a determination of soil moisture and pH; and fourth, an attempt to correlate these factors with the number of ac… more

A Solution for High Bacterial Counts in a Local Dairy, Denton, Texas

Description: It is the aim of this investigation to determine through routine checks if the bacterial count in the milk from Brooks Dairy Company is high and if so to determine the source. If it is found that the laboratory plate counts are unnecessarily high, it is the further purpose of this paper to make recommendations for improvements in the quality of milk produced by this dairy plant.

A Study of Hereditary Predisposition to Cardiovascular Diseases

Description: Because the many physicians and students of heredity have not been closely associated in finding that the causes of cardiovascular diseases might lie, in a large measure, to an inherited predisposition, this study has been undertaken; first, to contribute to several more case studies of cardiovascular diseases to the knowledge of heredity; second, to find if there is a possible successive occurrence of cardiovascular diseases in generation after generation; and third, to determine a possible mo… more

A Study of the Bacterial Flora of Food Utensils in Hardin College Cafeteria and Twenty-Five Eating Establishments in Wichita Falls, Texas

Description: The problem of this thesis consists primarily of a bacteriological survey of the eating utensils of Hardin College Cafeteria and twenty-five other eating establishments in the city of Wichita Falls, Texas. This investigation was made primarily with reference to a determination of the possible presence of typhoid and related organisms, and secondarily to an investigation of the actual presence of those bacterial organisms associated with the more common outbreaks of food poisoning.
