Purpose: Cyclosporine(CsA) is a potent immunosuppressant but the use of CsA is associated with various side effects, especially nephrotoxicity. In tile kidney, salt depletion activates tile renin-angiotensin-aldosteron(RAS) system and accentuates chronic CsA nephropathy. We postulate that angiotensin converting enzyme inhibitors(ACEI) can prevent chronic CsA nephropathy, since ACEI may inhibit this cascades. This study was aimed to assess the effect of ACEI on chronic cyclosporin nephropathy in salt depleted rats. Methods: 36 Fischer-344 rats were divided into 6 goups. Group I received normal salt diet(NSD). Group II received a low salt diet(LSD). Group III received CsA with a NSD. Group IV received CsA with a LSD. Group V received NSD+CsA with ACEI. Group VI received LSD+CsA with ACEI. Rats were sacrificed after six weeks and the glomerular filtration rate(GFR), serum sodium, potassium and whole blood cyclosporine levels were measured. Renal tissues me sampled for the observation of histological changes. Results: No differences in blood CsA level & serum sodium were found between groups during the course of this experiment. Serum potassium in group VI was significantly increased compared with group IV and V (P<0.05). In groups treated with CsA only and in those where CsA was combined with ACEI, GFR was found to be significantly more decreased in LSD than NSD, and GFR in group V was significantly decreased in comparison with group III (P<0.05). Renal histologic lesions associated with CsA which consisted of cortical interstitial fibrosis, tubular atrophy and hyalinization of arterioles were more severe in tile LSD group. But, no differences were observed between tile groups treated with CsA and ACEI, and the groups treated with only CsA. Conclusion: Salt depletion associated with the activation of the RAS system accentuated chronic CsA nephrotoxicity, but, ACEI could not reduce the functional and morphological changes of salt depleted kidneys, in which nephropathy can be exacerbated in spite of the blocking of the angiotensin II pathway. further studies are required to elucidate whether Am ameliorated the effect of salt-depleted CsA nephrotoxicity upon the effective renal blood flow.

This study was conducted to develop low-salinity Kimchi with acetic acid, starters and fruits added for health and taste. The quality characteristics of the developed Kimchi by storage period and salt concentrations were investigated herein. The effects of salinity and fermentation temperature ($0^{\circ}C$, $5^{\circ}C$) on the quality characteristics of low-salinity Kimchi were investigated through physicochemical and microbiological analysis. The sensory characteristics are shown in the results below. The pH and acidity were quickly changed by higher temperature over longer storage periods, with gradual decrease in the pH accompanied with an increase in acidity. The microbiological analysis revealed increase in the total cell number regardless of the concentration and strain added during the storage period. Finally, test of the overall acceptability with regard to sensory characteristics according to the different strain sets in low-salinity Kimchi showed the average score for smell, salty taste and overall acceptability were highest in the hetero-fermentation strain group.

Responses of atrial natriuretic peptide (ANP), aldosterone and renin release to acute volume expansion were compared in normotensive Wistar and spontaneously hypertensive rat (SHR) fed low or high-sodium diet (2 or 25 mmol Na/100 g diet). Experimental diets were fed for 6 weeks from 7-week-old and the growth rate was similar in all groups. In the morning of the experiment, catheters were inserted under ether anesthesia in femoral artery for pressure recording and blood collection, femoral vein for saline infusion, and bladder for urine collection. Then, the rats were placed in restraining cages. When the rats were recovered from anesthesia and the arterial pressure became stabilized, control urine and blood samples were collected. Then, 0.9% saline was infused for 30 min for volume expansion (3% BW). Arterial pressure was significantly higher in the high-sodium SHR but there was no difference between the two groups of Wistar rats. Control plasma levels of Na, K, ANP, renin activity, and hematocrit were not different among the 4 groups. However, plasma aldosterone level was significantly higher in the low-sodium groups. Wistar low-sodium rats showed approximately two times higher plasma aldosterone level than the SHR counterpart. Volume expansion produced a marked increase in plasma ANP level, especially in the high-sodium groups. The low-sodium groups of both strains showed approximately two-fold increase in plasma ANP level. Following a volume expansion plasma aldosterone level and renin activity decreased in all groups. There was a significant logarithmic positive correlation between plasma renin activity and aldosterone concentration. The low-sodium rats produced a greater increase in aldosterone release by small increase in plasma renin than did the high-sodium rats. The low- and high-sodium rats produced a similar degree of diuresis and natriuresis after volume expansion. However, SHR produced a greater natriuresis than did the Wistar rats. The above results indicate that regulatory mechanisms of ANP, aldosterone and renin release are different between the normotensive and hypertensive rats, and between the low- and high-sodium groups.

Purpose: This study aimed to examine the compliance to a low-salt diet, sodium intake, and preferred salty taste in elderly patients with hypertension. Methods: A cross-sectional descriptive design was used. Participants were 105 elderly patients with hypertension living in a rural area. The compliance with a low-salt diet, sodium intake, and preferred salty taste, blood pressure, body mass index, and waist circumference were measured, and compared according to the general characteristics and the levels of blood pressure. Descriptive statistics, $X^2$-test, t-test, and ANOVA were used for data analysis. Results: compliance with a low-salt diet was marginally elevated. Sodium intake was relatively high and the main sources were seasonings and vegetables. The participants tended to prefer high levels of salt. Sodium intake was significantly higher the hypertensive individuals (stage I and II) compared to prehypertensive subjects on a normal maintenance diet. Sodium intake from vegetables was also significantly different between the two groups. Conclusion: Nursing intervention for hypertensive elderly patients should include strategies to decrease sodium intake.

The present study was carried out to investigate the relationship between the patients with toxemia of pregnancy and sodium, potassium and chlorine content in their blood serum and the intake diet. The author analyzed or titrated the concentration of serum and diet electrolytes for the antenatal and gynecologic inpatients (19 normal and 17 toxemic pregnant women ranged 23 to 32 years old) of the Han gang sacred Heart Hospital in Seoul and also determined their daily salt intake. The results obtained can be summarized as follows. 1. In the patients with toxemia of pregnancy mean sodium concentration in serum $(147.2{\pm}11.0mEq/L\;(338.5mg/dl)$ was greater than that of normal pregnant women (140 mEq/L corresponding to 322mg/dl) 2. In the toxemic pregnant women serum chlorine level (mean $113.4{\pm}5.6 mEq/L$ corresponding to 402.5mg/dl) showed the increase of 9.9 mEq /L(36.9 mg/dl) when compared to mean value of normal pregnant women(103.5mEq/L corresponding to 365.6mg/dl). 3. Mean potassium content in pregnant women with toxemia($4.59{\pm}0.7mEq/L$ corresponding to 17.9mg/dl) was similar to that of normal pregnant women(4.2mEq/L corresponding to 16.3mg/dl). 4. It was found that the salt content detected in the diet of toxemic pregnant women (mean $20.84{\pm}2.1g/day$) was greater than daily mean salt intake of normal pregnant women (19g).

The study aim was to examine the effect of sensory responses of subjects after 6-month dietary sodium reduction with the aid of nutritional education. Fourteen female college students voluntarily restricted their sodium intake for 6 months, during which time they received nutritional education on the low sodium diet. As a control group, 10 students, whose anthropometric measurement, sodium intake behavior, and blood pressure were not different from those of the experimental group, were maintained on a normal diet. For the sensory responses of subjects, the salt taste perception and pleasantness for graded (0.15-1.3%) NaCl solutions were measured by a 9-point hedonic scale. The optimum sodium concentration, urinary sodium excretion, and blood pressure were measured. All the measurements were done at the beginning and end of the experiment. The sensory evaluation revealed an absence of any difference between the two groups in salt taste perception and pleasantness responses at the beginning. After 6-month adaptation, the experimental group subjects showed higher responses to low NaCl solution (0.15, 0.3, 0.5%) in salt taste perception and pleasantness evaluation while the control group subjects exhibited the opposite response. The optimum sodium concentration was reduced from 105.6 mmol to 80.7 mmol (p = 0.015) and the urinary sodium excretion was also reduced from 1,398 mg to 906 mg (p = 0.041) only in the experimental group. Systolic blood pressure was significantly reduced in the experimental group, although there was no correlation between the urinary sodium excretion and blood pressure. The optimum sodium concentration was negatively correlated with the urinary sodium excretion (r = 0.418, p = 0.053), indicating that adaptation to low sodium diet can reduce sodium intake. Further study on the individual responses of subjects on a low sodium diet by periodical evaluation may provide useful data for setting the duration needed to stabilize a lowered appetite for sodium.

Objectives: This study was carried out to measure knowledge, attitude, and practice and related factors of low-salt diet among university students. Methods: Data from a convenience sample of 251 nursing and engineering students of two universities in south-western part of Korea were collected during March 16~20, 2015 using a self-reporting questionaire and urine test. The instruments developed by Lee and Song(1999) were used to measure knowledge and practice, and Ahn(2013) for attitude toward low-salt diet. A spot urine salt stick($SaltSinal^{(R)}$) was also used to evaluate practice of low-salt diet. Data were analyzed using SPSS 21.0, and t-tests, ANOVA, Pearson correlation, and Scheffe test were used. The study was IRB approved. Results: Knowledge, attitude, and practice of low-salt diet was low and spot urine salt level was high among university students. Knowledge and attitude were higher and spot urine salt level was lower among nursing students. Knowledge and attitude were related to gender and drinking. Living arrangement, monthly allowance, smoking, frequency of eating-out, frequency of breakfast were shown not to be related to knowledge and attitude. None of the variable investigated were significantly related to practice of low-salt diet. However, spot urine salt was related with gender, living arrangement, and smoking. Conclusions: A rigorous health education is necessary in order to lower dietary salt among university students. Considering frequent eating-out among university students, it is also very important to lower salt amount in foods sold on- and off-campus.
