The Vocal And Behavioral Reactions Of The White Whale, Or Beluga, (Delphinapterus Leucas) To Underwater Playback Of Natural And Synthetic Beluga Sounds, David W. Morgan

Open Access Dissertations

Underwater playback of natural and synthetic sounds was shown to be an effective tool for investigation of communication in Delphinapterus leucas, the beluga. Natural sounds were used to determine the significance of the sounds to the animals, and synthetic sounds to determine some of the parameters of the sounds that had an effect on their significance. The general, overall response of captive animals was an increase of interest in the sound source during the playback, with decreasing interest in the three minutes following playback. The general response of free-swimming belugas was a decrease of vocal emissions. A strong, stereotyped, …

Glyoxal And Estradiol Mediated Alterations In Rat Uterine Histone Acetylation, Robert Louis Procaccini

Open Access Dissertations

The immature rat uterus was developed as a model in which to measure alterations in his tone acetylation in a target organ following hormonal stimulation. The effect of various glyoxal derivatives on his tone acetylation and several other parameters was measured in the uterine tissue of untreated and estradiol treated animals. Six day treatment with glyoxal monohydrate and methylglyoxal-bis-guanyl-hydrazone (Methyl-GAG) decreased uterine wet weight and partially blocked estradiol mediated alterations in uterine wet weight in animals receiving concomitant estradiol and glyoxal treatment.

The dose dependent in vitro inhibition of uterine histone acetylation is thought to occur through direct action on …

Pargyline, Succinic Acid And L-Ascorbic Acid As Protective Agents Against Hyperbaric Oxygen Toxicity: Possible Involvement Of Altered Gamma-Aminobutyric Acid And Ammonia Metabolism, Robert Alfred Schatz

Open Access Dissertations

The mechanisms whereby pargyline, succinic acid and absorbic acid protect against hyperbaric oxygen convulsions, pulmonary damage and mortality following hyperbaric oxygen exposure were investigated in relation to the effects of these agents on hyperbaric oxygen-induced alterations in brain gamma-aminobutyric acid and ammonia metabolism.

Exposure to hyperbaric oxygen (60 pounds per square inch, gauge pressure) produced convulsions, post-exposure lethality and elevation in lung weight, lung water content and lung hemoglobin content. Pargyline, succinic acid and ascorbic acid provided partial production against all of the above aspects of toxicity.

Comparison of the doses of pargyline, succinic acid and ascorbic acid that provided …
