this experiment was carried out to study the effect of sodium chloride from drinking water and feed intake on the quality of egs from laying hens. four hundred and twenty native and white leghorn laying hens ranging from 36 to 43 weeks of age were used. seven experimental treatments containing different levels of salt supplied by feed and/or drinking water were compared. increasing salt int...

This article describes the progress-as well as the challenges and limitations-in reducing salt intake in Costa Rica. The National Plan to Reduce Public Consumption of Salt/Sodium in Costa Rica 2011 - 2021 was complemented with multisectoral programs and projects specifically designed to: 1) determine sodium intake and the salt/sodium content of the most widely consumed foods; identify the consu...

Corin is a protease that activates atrial natriuretic peptide, a cardiac hormone important in the control of blood pressure and salt-water balance. Here we examined the role of corin in regulating blood pressure and sodium homeostasis upon dietary salt challenge. Radiotelemetry-tracked blood pressure in corin knockout mice on a high-salt diet (4% sodium chloride) was significantly increased; ho...

To identify characteristics that may contribute to salt sensitivity, we conducted studies of normal subjects who are at risk for hypertension, namely blacks, subjects older than 40 years of age, and first-degree relatives of subjects with essential hypertension. We also formulated definitions for salt sensitivity and resistance with a short-term volume expansion and contraction protocol and add...

Relati ve viscosities of some mineral salts viz; sodium sulphate, potassium sulphate, ammon ium sulpha te and magnes iu m sulphate, at di ffe rent concentrations have been determined in binary aqueous solutions of urea (mole-frac tions of urea, XII!""" = 0.0 10, 0.025 , 0. 040, 0.055 and 0.070) at 308. 15K and in XII!""" = 0.025 at di fferent temperatures. The data have been evaluated using l o...

A group of young adult subjects was placed on self-maintained, low sodium diets for 5 months. Taste responses to salt in solutions, soups, and crackers were determined both during the 2 months preceding diet initiation and during a 5-month period when subjects lowered their sodium intake. Taste responses were also determined in a control group with ad libitum salt consumption throughout the sam...

Four patients with salt-losing congenital adrenal hyperplasia (CAH) who had stopped mineralocorticoid therapy for several years, showed raised plasma concentrations of 17OH-progesterone and plasma renin activity, despite adequate glucoticoid therapy. One patient was able to reduce urinary sodium excretion when the sodium intake was restricted. Another patient who was a salt-loser, developed sig...

Various studies have investigated the role of central opioid peptides in feeding behavior; however, only a few have addressed the participation of opioids in the control of salt appetite. The present study investigated the effect of intracerebroventricular injections of the δ-opioid antagonist, naltrindole (5, 10 and 20 nmol/rat) and the agonist, deltorphin II (2.5, 5, 10 and 20 nmol/rat) on sa...
