Measurement Of Autonomic Function In Renal Disease And Diabetes, Ann King Cashion
Measurement Of Autonomic Function In Renal Disease And Diabetes, Ann King Cashion
Theses and Dissertations (ETD)
Renal disease and diabetes lead to dysautonomia resulting in consequences ranging from gastroparesis to sudden death. New technologies to detect dysautonomia, such as 24-hr heart rate variability, are being evaluated and compared to traditional evoked tests. These advances have, however, lead to a lack of standardization in testing batteries, procedures, and reporting formats. This series of 3 studies psychometrically assessed measures of autonomic function (AF) and explored relationships among objective and subjective measures in healthy adults and uremic patients. Participants underwent evoked tests that included change in heart rate with deep breathing and Valsalva. In addition, measures of 24-hr HRV …

This study evaluated Na/K-ATPase alpha 1- and alpha 3-subunit isoform polypeptide expression and localization during bovine preattachment development. Na/K-ATPase cation transport activity from the one-cell to blastocyst stage was also determined by measuring ouabain-sensitive 86Rb+ uptake. Both alpha1- and alpha 3-subunit polypeptides were detected by immunofluorescence to encircle the entire cell margins of each blastomere of inseminated zygotes, cleavage stage embryos, and morulae. Immunofluorescent localization of alpha1-subunit polypeptide in bovine blastocysts revealed an alpha1 immunofluorescence signal confined to the basolateral membrane margins of the trophectoderm and encircling the cell periphery of each inner cell mass (ICM) cell. In contrast, alpha …

Urinary N-acetyl-\beta-D-glucosaminidase (NAG) levels of twenty healthy full-term newborns and of seventeen full-term newborns with perinatal asphyxia were evaluated within the first 48 hours of life. Urinary NAG levels and NAG indices (urinary NAG/urinary creatinine ratio) were sig-nificantly higher in newborns with perinatal asphyxia than control group (p

Vitamin E and other antioxidants prevent or minimize oxidative damage in biological systems. The level of antioxidant defense sufficient to protect the organism from high free radical concentrations is one of the new horizons for Vitamin E research. The role of Vitamin E as a protective agent aganist oxidative stress was evaluated by meas-uring the antioxidant enzyme catalase (CAT) activities in different tissues of Swiss male albino rats aged two months. In this study, rats were divided to three groups; control (n=10), E 1 (n=5) which received 25 mg/kg. per day of Vitamin E, IM. for 10 days and E …

Diethylstilbestrol (DES), nonsteroid in structure, is an artificial estrogen derivative and is used as an anabolic agent. It is known that diethylstilbestrol causes genetic disorders and toxic effects leading up to carcinoma even in amounts below its residual levels. For this purpose, a dose of 60µm/kg/day of DES dissolved in 0,1 ml corn oil has been administered to rats by oral gavage for varying periods of 20, 50 and 100 days periods. Rat renal tissue samples, following routine electron microscopical procedure, have been examined by transmission electron microscopy. Following diethylstilbestrol administration, glomerular capilleries seemed dilated along with occasional basement membrane …
