Clinical disorders of water regulation are relatively common and occur with severity ranging from profound and easily recognizable disturbance of body water balance to mild and often clinically inapparent. The development of sensitive and specific radioimmunoassay procedures capable of quantitating the level of AVP in plasma and urine has allowed elucidation of the pathophysiology of [...]

A short survey is given over changes in water metabolism from early foetal life to infancy. The close connection between water metabolism and body composition is described as well as the changes taking place after birth. The impact of intrauterine malnutrition, delivery and postnatal nutrition is discussed. PMID: 6351536 [PubMed - indexed for MEDLINE
To investigate the interaction between antidiuretic hormone (ADH) and renin-angiotensin system, plasma ADH and plasma renin activity (PRA) were determined in normal subjects (n = 10) under various hydrated states. Four experimental conditions, i.e., water loading, infusion of hypertonic saline, acute dehydration induced by furosemide and postural changes, were chosen. 1. Upright posture decreased plasma [...]
Water metabolism is a major problem in infants of very low birth weight. Their surface is proportionally larger, they have a relatively low intracellular water volume and a high extracellular and total body volume. Kidney function is immature compared to bigger infants, and the neuroendocrine function is also immature. Finally the large surface and the [...]
This study was designed to investigate the hypothesis that mitral valve prolapse (MVP) can be induced after diuresis in women without the abnormality who have characteristic body habitus. Fifteen tall, slim, healthy female volunteers with a normal cardiac findings, echocardiogram, and history were investigated after mild diuresis with furosemide and after placebo. All subjects lost [...]
A short survey is given over water metabolism from early fetal life to infancy. The close connection between water metabolism and body composition is described as well as the changes taking place during growth. The impact of intrauterine malnutrition, delivery and postnatal nutrition is discussed, and it is pointed out how the premature infant differs [...]

There is increasing evidence that mild dehydration plays a role in the development of various morbidities. In this review, the effects of hydration status on chronic diseases are categorized according to the strength of the evidence. Positive effects of maintenance of good hydration are shown for urolithiasis (category lb evidence); constipation, exercise asthma, hypertonic dehydration [...]
