Quantification of Ethanol Levels in Zebrafish Embryos Using Head Space Gas Chromatography
Published on: February 11, 2020
Abstract:
Chronic ethanol consumption consistently resulted in mild hypertension in the male Wistar rats used in the present study. The ethanol-treated animals also have reduced 24-hour urinary output and significant sodium retention when compared to the controls. Total plasma volume was estimated using the technique of indicator dilution, and an increase of 20% was observed in the ethanol-treated animals. Vascular smooth muscle responsiveness to noradrenaline in vitro was not different between the two groups of animals. Therefore the blood pressure elevation in the ethanol-treated animals seems to be associated with sodium retention and plasma volume expansion, and probably is unrelated to altered vascular responsiveness.

Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart beats)...

Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction while...
