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

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

Date: 1949
Creator: Barberousse, Loris J.
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

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

Date: 1949
Creator: Estes, Charles M.
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

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

Date: 1949
Creator: Robertson, William George
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.
