Adrenomedullin (AM) exerts profound natriuretic and vasodilatory effects in conscious animals. This newly discovered hormone also acts in the central nervous system to inhibit water drinking and in the pituitary gland to reduce basal and stimulated ACTH release. We investigated whether the natriuretic action of AM in kidney was matched by a central nervous system action to decrease salt intake....

The experiment aimed to study the influences of drinking natural saline water on thermoregulation, blood constituents and semen quality of White Leghorn cocks under heat stress in desert conditions. A total number of 60 cocks (22-wk-old and body weight of 1555 g ± 36.11) were divided randomly into four equal groups which in turn divided randomly into three equal replicates. The 1 st treatment (...

Saline waters treatment has become increasingly important for drinking water supply in a greater part of the world. However, some serious limitations had recently been discovered during water treatment, among them the boron problem seems to have a critical meaning. According to the WHO regulations (2011), the boron concentration should be reduced to less than 2.4 mg/L for drinking water. The pu...

OBJECTIVE Intrauterine glucocorticoid (GC) exposure is associated with disturbances in feto-placental growth. This study aimed to investigate whether folic acid supplementation can prevent dexamethasone (Dex)-induced feto-placental growth restriction. MATERIALS AND METHODS Female C57BL/6J mice were subject to four different treatments, respectively: normal drinking water plus saline injection...

We demonstrate here that acute third ventricle injections of GR 113808, a highly selective 5-HT4 antagonist, decrease water intake induced by a previous salt load while potentiating drinking elicited by hypovolemia induced by previous subcutaneous administration of polyethylene glycol in male Wistar rats (200 +/- 20 g). At the dose of 160 nmol/rat, third ventricle injections of GR 113808 induce...

Central injection of ANG II has been proposed to have dual effects on salt appetite including a direct stimulatory effect and an indirect inhibitory effect through an activation of central oxytocinergic neurons. The inhibition was demonstrated by pretreating rats with central ornithine vasotocin (OVT; oxytocin antagonist) 30 min before a central ANG II injection. The OVT pretreatment produced a...

The debate surrounding the safety of shale gas development in the Appalachian Basin has generated increased awareness of drinking water quality in rural communities. Concerns include the potential for migration of stray gas, metal-rich formation brines, and hydraulic fracturing and/or flowback fluids to drinking water aquifers. A critical question common to these environmental risks is the hydr...
