Effects Of Strong Oxidants Present In Acer Spp. On Hemolysis Methemoglobin Production In Equine Erythrocytes, Gabrielle Mcgeorge, Jeffrey Lehman
Effects Of Strong Oxidants Present In Acer Spp. On Hemolysis Methemoglobin Production In Equine Erythrocytes, Gabrielle Mcgeorge, Jeffrey Lehman
Undergraduate Honors Thesis Projects
Maple toxicosis is a deadly condition affecting equines after they have ingested wilted leaves of the genus Acer (i.e., maple species). It is characterized by hemolytic anemia and methemoglobinemia. Although the toxins responsible for causing toxicosis have not been identified, they are thought to be strong oxidants. The objective of this study is to determine the effect of eight compounds (galloyl derivatives) found in Acer spp. on hemolysis and methemoglobin production in bioassays with equine erythrocytes. Seven of the compounds are known constituents of Acer spp. that are commercially available. One of the compounds--acertannin--was isolated and characterized from leaf extracts …
Release Kinetics Of Methylene Blue In Pluronic F-127 Hydrogel, Meredith Hayden
Release Kinetics Of Methylene Blue In Pluronic F-127 Hydrogel, Meredith Hayden
Animal Science Undergraduate Honors Theses
“Between January 1998 and March 2000, veterinarians at the ASPCA National Animal Poison Control Center (NAPCC) consulted on more than 1,050 cases of accidental exposures to acetaminophen and 1,100 cases of ibuprofen ingestion in dogs and cats” (Richardson, 2000).
NSAID toxicity has become an increasingly common occurrence in small companion animals within the last decade due to widespread usage (Zhou, Boudreau, & Freedman, 2014). Depending on the specific drug, treatment is centered around early decontamination and prevention of kidney and hepatic damage, and methemoglobanemia. Currently, methemoglobanemia is treated with intravenous delivery of methylene blue and less commonly through oral administration. …
Immunostimulatory Effects Of Antigen-Conjugated Inp/Zns Quantum Dot Nanoparticles In An Avian Model, Christopher Lyle
Immunostimulatory Effects Of Antigen-Conjugated Inp/Zns Quantum Dot Nanoparticles In An Avian Model, Christopher Lyle
Graduate Theses and Dissertations
Due to their unique physicochemical and enhanced immunostimulatory properties, quantum dot (QD) nanoparticles have shown increasing promise in biomedical research applications including bioimaging, drug delivery, and as vaccine adjuvants. Toxicity, however, remains a concern for the use of QD in these applications and thus, there is an increased demand for effective in vitro and in vivo systems to measure the bioactivity of QD. In this study in vitro and in vivo chicken models were used to investigate the effects of QD on innate and adaptive immunity. Chicken macrophage cultures were treated in vitro with QD to measure macrophage activation and …
The Impact Of Endocrine-Disrupting Chemicals On Wildlife Conservation, Eda Reed
The Impact Of Endocrine-Disrupting Chemicals On Wildlife Conservation, Eda Reed
Honors Theses
Endocrine-disrupting chemicals (EDCs), such as those from plastics and pesticides, have been hypothesized to affect wildlife populations. According to the U.S. National Institute of Environmental Health Sciences, EDCs ‘are chemicals that may interfere with the body’s endocrine system and produce adverse developmental, reproductive, neurological, and immune effects in both humans and wildlife.’ A growing number of studies suggest wildlife are being exposed to EDCs, but how EDCs affect wildlife health and wildlife conservation is less well-understood. Through scientific literature analysis and a survey of wildlife conservationists and practitioners, this study aims to determine the current state of knowledge and data …

Lynne Sneddon, PhD
The workshop on Three Rs Approaches in the Production and Quality Control of Fish Vaccines aimed a) to identify animal tests currently stipulated for the production and quality control of fish vaccines and to highlight animal welfare concerns associated with these tests; b) to identify viable options to replace, reduce, and refine animal use for fish vaccine testing; and c) to discuss the way forward and set out how the Three Rs may be implemented without jeopardizing the quality of the vaccines. The workshop participants -- experts from academia, regulatory authorities, a scientific animal welfare organization, and the fish vaccine …

Reversible Downregulation Of Hypothalamic-Pituitary-Gonadal Axis In The Stallion With A Third-Generation Gnrh Antagonist, Gabriel Monteiro Davolli
Reversible Downregulation Of Hypothalamic-Pituitary-Gonadal Axis In The Stallion With A Third-Generation Gnrh Antagonist, Gabriel Monteiro Davolli
Theses and Dissertations--Veterinary Science
The objectives of this thesis were: (1) to evaluate the downregulation of the stallion hypothalamic-pituitary-gonadal (HPG) axis by a GnRH antagonist (acyline) based upon endocrine, seminal, testicular and behavioral effects, and (2) to assess recovery after treatment. Stallions were treated for 50 days (n=4; 330µg/kg acyline q 5d) and controls (n=4) received vehicle alone. Stallions were assessed pre-treatment and for 72 days after last treatment. Treatment induced declines (p<0.05) in FSH, LH, testosterone (to castrate levels) and estrone sulfate. Gonadotropins and testosterone returned to control values within nine days and estrone sulfate by 14 days after treatment discontinuation. Acyline-treated stallions failed to respond with FSH, LH and testosterone increase after exogenous GnRH stimulation (25µg gonadorelin, IV) compared to pre-treatment and control stimulation. Total sperm numbers and motility were reduced in acyline-treated stallions, as well as total seminal plasma protein and testicular volume (p<0.05). Time to ejaculation was increased in acyline group (p<0.5). Testicular, sexual behavior and most seminal parameters regained normal levels within 72 days after treatment ceased. Sperm output of acyline-treated stallions was regained within seven months after ending treatment. Acyline reversibly suppressed the stallion HPG axis, thus has potential for treating the androgen-dependent Equine-Arteritis-Virus carrier state and as behavior modulator.

Horse Problems In The Kimberleys, M R. Gardiner
Horse Problems In The Kimberleys, M R. Gardiner
Journal of the Department of Agriculture, Western Australia, Series 4
A review of current horse disease and ill-thrift problems in the Kimberley region of Western Australia, with emphasis on the "Kimberley horse disease".
DISEASES and other conditions affecting the health and working capacity of the horse have long had an important bearing on the economy of the cattle and sheep industries of the northern part of Western Australia.
Under present conditions it is impossible to muster stock on the large pastoral leases in the Kimberley districts without the aid of horses, and many other operations would be more difficult if stockmen were denied their services.
