OBJECTIVE: To estimate the effects of maternal intravenous hydration on amniotic fluid volume in normal pregnancies. METHODS: Women undergoing an amniocentesis for the evaluation of fetal lung maturity before an elective cesarean delivery were eligible to participate. An amniotic fluid index (AFI) was obtained before the amniocentesis, and at the time of the amniocentesis the [...]
OBJECTIVE: To evaluate the effect of long-term (1-week) oral hydration on amniotic fluid volume in women with an amniotic fluid index (AFI) < 10th percentile. STUDY DESIGN: This prospective, nonrandomized, interventional study was conducted on 30 women with AFI < 10th percentile. Study inclusion criteria were singleton pregnancy, well-established gestational age, intact membranes, no maternal [...]
OBJECTIVE: To evaluate the effect of maternal oral hydration on amniotic fluid index (AFI) in women with pregnancy-induced hypertension. METHODS: Five women with pregnancy-induced hypertension and five normotensive gravidae at 32-37 weeks gestation with normal AFI (8-18cm) were hydrated by oral intake of 2L of water over 1 h. Both groups were similar in age, [...]
The purpose of this review is to study general behaviour of human systems with respect to the environmental conditions. This type of work will be of profound significance to record the effect of medical treatment in various climatic zones of the world (Arayne and Saify, 1975). We attempted to discuss various facts which would be [...]
The purpose of this study was to examine the thermoregulatory sweating control parameters of threshold temperature and sensitivity to determine whether 1) these variables were altered by hypohydration level and exercise intensity and 2) these alterations, if present, were additive and independent. Nine heat-acclimated men completed a matrix of nine trials: three exercise intensities of [...]

During exercise in the heat, sweat output often exceeds water intake, resulting in hypohydration, which is defined as a body fluid deficit. This fluid deficit is comprised of water loss from both the intracellular and extracellular fluid compartments. Hypohydration during exercise causes a greater heat storage and reduces endurance in comparison with euhydration levels. The [...]
