Young barley plants, Hordeum vulgare cv. Chevron, were subjected to a sodium chloride concentration of 100 m-equiv/l. In a "continued" treatment, the salinity stress was maintained for 15 days. In a "removed" treatment, sodium chloride was removed from the substrate after 5 days, and the subsequent response was studied over a period of 10 days.

Heart Remodeling

BACKGROUND. Increased salt intake is associated with a number of cardiovascular events, including increased blood pressure (BP) and the development of left ventricular hypertrophy (LVH). However, there is much evidence that a high content of sodium chloride in the diet does not always lead to an increase in BP, but almost inevitably causes cardiac remodeling, in particular, LVH. Many aspects of myocardial remodeling induced by high sodium content in the food have not been studied enough. THE AIM of the study was to trace the echocardiographic changes in Wistar rats fed the high salt ration and the high salt ration supplemented with soy proteins.MATERIAL AND METHODS. Echocardiography and BP measurements were performed on male Wistar rats, divided into three groups. The first (control; n = 8) included rats that received standard laboratory feed (20.16 % animal protein and 0.34 % NaCl); the second (n = 10) – animals that received standard feed and 8 % NaCl (high salt ration). The third group (n = 10) consisted of rats who consumed a low-protein diet containing 10 % soy protein isolate (SUPRO 760) and 8 % NaCl. The follow-up period was 2 and 4 months.THE RESULTS of the study showed that: (1) the intake of a large amount of salt with a diet does not necessarily lead to the formation of arterial hypertension; (2) despite the absence of a distinct increase in BP, under these conditions signs of cardiac remodeling, in particular, LVH, appear rather quickly; (3) supplementing a high-salt diet with soy isolates counteracts the development of LVH.CONCLUSION. High salt intake with food can cause heart remodeling, regardless of blood pressure, while soy proteins can counteract this process.

Rigid Cell Wall

The optical densities of suspensions of cells of Halobacterium cutirubrum, H. halobium, or H. salinarium, grown in media containing 4.5 M sodium chloride, increase as the salt concentration of the suspending medium decreases, until a maximum is reached at about 2 M; below this concentration there is an abrupt decrease in optical density. The cells are rod shaped in 4.5 M salt and change, as the salt concentration decreases, through irregular transition forms to spheres; equal numbers of transition forms and spheres are present at the point of maximum turbidity, while spheres predominate at lower salt concentrations. Cells suspended in 3.0 M salt, although slightly swollen, are viable, but viability decreases rapidly with the more drastic changes in morphology at lower salt concentrations. Cells grown in the presence of iron are more resistant to morphological changes but follow the same sequence. Cells "fixed" with formaldehyde, at any point in the sequence, act as osmometers and do not rupture in distilled water although their volume increases 10–14 times. The results indicate that the red halophilic rods require a high sodium chloride content in their growth or suspending medium to maintain a rigid cell wall structure.

Hypotensive Response

High dietary intake of linoleic acid lowers arterial pressure, and, in vitro, linoleic acid inhibits the enzymatic activity of renin. The purpose of the present study was 1) to evaluate the effect of intravenous infusion of linoleic acid on blood pressure in normotensive and hypertensive Sprague-Dawley rats and 2) to determine whether the hypotensive response to linoleic acid infusion is caused by inhibition of circulating renin. Blood pressure was decreased (P less than 0.01) by linoleic acid infusion in normotensive sodium chloride-deprived animals and in animals with two-kidney, one-clip hypertension. In contrast, linoleic acid infusion did not affect blood pressure in normotensive rats on a "normal" or high sodium chloride intake, in rats with deoxycorticosterone acetate (DOCA)-salt hypertension, and in anephric rats. In sodium chloride-deprived rats, the reduction of blood pressure by linoleic acid infusion was associated with increased plasma renin activity (P less than 0.05); serum angiotensin-converting enzyme activity was unchanged. The in vitro enzymatic activity of exogenous renin in plasma of anephric rats was not affected by linoleic acid infusion. In two-kidney, one-clip hypertensive animals, pretreatment with indomethacin did not alter the hypotensive response to linoleic acid. Thus, although linoleic acid infusion lowered blood pressure in high renin but not in low renin states, the reduction of blood pressure was not related to inhibition of circulating renin or to alterations of endogenous prostaglandin biosynthesis.

The Impact

Abstract Italian salami is a cured meat with high sodium contents which is easy, fast and convenient to consume. Starter cultures are used to improve its sensory characteristics and refine its technological manufacturing process. The goal of this study was to reduce the sodium content in Italian salami through the partial replacement of sodium chloride by potassium chloride, magnesium chloride and calcium chloride, and evaluate the viability of the Lactobacillus sp. and Staphylococcus sp. cells found in the starter culture. Four formulations were elaborated: one with, and one without the starter culture, but both with the addition of sodium chloride; and two with the partial replacement of 60% of the sodium chloride: the first with KCl, and the other with a mixture of KCl, MgCl2 and CaCl2. Physicochemical and microbiological evaluations were carried out to monitor the ripening and the quality of the final product. The partial replacement of NaCl by other salts (MgCl2, CaCl2, KCl) did not interfere in the growth of the starter culture in the Italian salami, neither did it affect the majority of the physicochemical parameters of the Italian salami nor the microbiological quality of the final product.

Chloride Effect

The effect of selective dietary sodium and (or) chloride loading on blood pressure and renal blood flow (RBF) in the rat angiotensin II (AII) model of hypertension was determined. AII (200 ng/min) or saline was infused intraperitoneally. Diets were provided with either high or low concentrations of sodium, chloride or both ions for 22 days. The blood pressure of saline-treated animals was not increased by the high sodium chloride diet. Animals on a high sodium, high chloride diet had a significantly greater increase of blood pressure at 8, 15, 18, and 22 days of AII infusion compared with AII-treated animals on a low sodium, low chloride diet (p < 0.05). Selective dietary loading of either high sodium or chloride in AII-treated rats produced no greater elevation of blood pressure than AII with the low sodium, low chloride diet. Selective high dietary chloride was associated with a lower RBF in AII- and vehicle-treated rats compared with low dietary chloride. The chloride effect on RBF was greater in AII-treated animals. In conclusion, both sodium and chloride are necessary to produce the maximum increase of blood pressure in AII animals. AII enhances the decreased RBF induced by dietary chloride.Key words: angiotensin II, sodium chloride, blood pressure.
