Oxytocin’S Effects On Sickness Behaviours, Anxiety Responses, And Immune Function In Adult Male Mice, Julie Deleemans Nov 2016

Oxytocin’S Effects On Sickness Behaviours, Anxiety Responses, And Immune Function In Adult Male Mice, Julie Deleemans

Electronic Thesis and Dissertation Repository

The nonapeptide, oxytocin (OT), is implicated in a range of behavioural and physiological functions. However, OT's role in sickness behaviours remains unclear. This thesis examined effects of the OT agonist, carbetocin (CBT), and OT antagonist, L-368,899, on anxiety and locomotor sickness-related behaviours and pro-inflammatory cytokines, TNF-a and IL-6, in adult male CD-1 mice. Animals received 2 intraperitoneal treatment injections. The first treatment was carbetocin, L-368,899, or saline, while the second was lipopolysaccharide (LPS) or saline. Behaviours were evaluated via the light-dark test, and cytokines via immunoassay. OT antagonist treatment attenuated LPS induced perturbations in locomotor and anxiety-like behaviour, but …


Chronic Pancreatitis, Pain, And Anxiety In An Alcohol And High Fat Mouse Model, Tiffanie Clinkinbeard Jan 2016

Chronic Pancreatitis, Pain, And Anxiety In An Alcohol And High Fat Mouse Model, Tiffanie Clinkinbeard

Theses and Dissertations--Gerontology

Homeodynamic space (HDS) shrinks as vulnerability increases with aging and repeated damage to the cells. HDS is lost in alcoholic pancreatitis patients due to overconsumption of alcohol, smoking, and high fat diets. Etiologically relevant animal models for study of chronic pancreatitis (CP) are needed. In order to begin filling this gap a central purpose of this dissertation research was to examine relationships between the alcohol and high fat diet (AHF) and pancreatitis with attention to hypersensitivity and anxiety-like behaviors. The AHF diet induced pancreatitis described here etiologically mimics human risk factors of AHF consumption for advancement to alcoholic CP.
