Cessation Of Chronic Ethanol Intake Reverses Ultrastructural Alterations In Ileal M Cells, Robert Rosback Eversole

Masters Theses

Membranous (M) cells of the dome epithelium of ileal Peyer's patches have been shown to serve an antigen uptake function for mucosa associated lymphoid tissue. Hypergammaglobulinemia is a frequent accompaniment of chronic alcoholism in humans and the elevated antibody titers have been shown to be due in part to bacterial and dietary proteins. This study was conducted to demonstrate the morphological changes induced by chronic ethanol exposure in the ileal M cells in the rat.

Chronic ingestion of ethanol produces marked changes in the ultrastructure of M cells. All experimental animals showed distinct mitochondrial swelling with loss of matrix density, …

Psychophysiological Assessment Of Panic Disorder, Kent A. Koehn

Masters Theses

This study compared physiological and psychological measures between 9 subjects meeting the DSM-III-R criteria for panic disorder (PD) and 9 control subjects to identify psychophysiological differences that might be relevant to the etiology and maintenance of panic attacks. The subjects were assessed through a number of self-report measures and across three laboratory sessions involving five experimental conditions: baseline, role play, relaxation, mental arithmetic, and cold pressor. We measured electrodermal (EDG) and electro-myographic activity (EMG), heart rate (HR), and blood volume pulse (BVP) in terms of absolute values, reactivity, and habituation. Both groups were also assessed in their ability to accurately …
