The effects of Korean solar salt on an azoxymethane (AOM)/dextran sodium sulfate (DSS)-induced colon cancer C57BL/6 mouse model were studied. Korean solar salt samples (SS-S, solar salt from S salt field; SS-Yb, solar salt from Yb salt field), nine-time-baked bamboo salt (BS-9x, made from SS-Yb), purified salt (PS), and SS-G (solar salt from $Gu\acute{e}rande$, France) were orally administered at a concentration of 1% during AOM/DSS colon cancer induction, and compared for their protective effects during colon carcinogenesis in C57BL/6 mice. SS-S and SS-Yb suppressed colon length shortening and tumor counts in mouse colons. Histological evaluation by hematoxylin and eosin staining also revealed suppression of tumorigenesis by SS-S. Conversely, PS and SS-G did not show a similar suppressive efficacy as Korean solar salt. SS-S and SS-Yb promoted colon mRNA expression of an apoptosis-related factor and cell-cycle-related gene and suppressed pro-inflammatory factor. SS-Yb baked into BS-9x further promoted these anti-carcinogenic efficacies. Taken together, the results indicate that Korean solar salt, especially SS-S and SS-Yb, exhibited anti-cancer activity by modulating apoptosis- and inflammation-related gene expression during colon carcinogenesis in mice, and bamboo salt baked from SS-Yb showed enhanced anti-cancer functionality.

The aim of this experiment was to investigate the effects of Aqua-Acupuncture of Yukmijiwangtang(六味地黃湯) and Palmijihwang-tang(八味地黃湯) water extracts applied at the meridian points BL 23(賢兪) and GV 4(命門) to test the renal function in normal rats. The results obtained were as follows; 1. Among the effects of Aqua-Acupuncture of Yukmijihwangtang water extract at the merdian point BL 23 group, there were significant changes in water balance and urine volume over a 1 week period; Both decreasing and decreasing trends were exihibited. Urinary excretion of sodium and free water clearance changed significantly over a 2 week period; Both decreasing and increasing trends were exihibited, Urinary excretion of potassium, chloride and creatinine, plasma renin activity, plasma levels of aldosterone and atrial natriuretic peptide showed no significant differences compared to the contral group. 2. Among the effects of Aqua-Acupuncture of Palmljihwangtang water extract at the merdian point BL 23 group, there were significant changes in water balance and free water clearance over a 2 week period; a decreasing trend. Urinary excretion of creatinine changed significantly over a 2 week period; an increasing trend. Urinary excretion of chloride changed significantly over 1 week period; an increasing trend. The plasma levels of atrial natriuretic peptide changed significantly over 1 and 2 week period; an increasing trend. Urine volume, urinary excretion of sodium and pottasium, plasma renin activity and plasma level of aldosterone showed no significant differences compared to the control group. 3. Among the effects of Aqua-Acupuncture of Yukmijihwangtang water extract at the meridian point GV 4 group, there was significant decrease in water balance over a 2 week period; there was significant decrease in urine volwne and urinary excretion of sodium and creatinine over a 1 week period, followed by an increasing trend after 2 weeks. Urinary excretion of free water clearance demonstrated significant changes over both 1 and 2 week period; both increasing and decreasing trends were exihibited. Urinary excretion of chloride and plasma levels of aldosterone increased significantly over 1 and 2 week period. Plasma levels of atrial natriuretic peptide also decreased significantly. Plasma renin activity showed no significant differences compared to the control group. 4. Among the effects of Aqua-Acupuncture of Palmijihwangtang water extract at the meridian point GV 4 group, water balance and urinary excretion of chloride, plasma levels of aldosterone decreased significantly over both 1 and 2 week period. Urine volume and urinary excretion of pottasium decreased significantly. Urinary excretion of creatinine and urinary excretion of sodium changed significantly over both 1 and 2 week period. Urinary excretion of free water clearance, plasma renin activity and plasma level of atrial natriuretic peptide showed no significant differences compared to the control group. Seeing these results, I come to know that the effects Aqua-Acupuncture of Yukmijihwangtang and Palmijihwangtang water extracts at the meridian point BL 23 and GV 4 have affected the renal function differently. Seeing the results that BL 23 is a meridian point for Aqua-Acupuncture directly related to the kidney, I think, we can use Aqua-Acupuncture of Yuk-mijihwangtang and Palmijihwangtang water extracts to prevent and to treat the diseases related to kidney.

This study was conducted to develop low-sodium Korean food recipes and evaluate consumer acceptability of low-sodium Korean food. A total of 137 consumers assessed the overall acceptability based on a 9-point scale. Statistical analyses were performed using the SPSS package program (ver 20.0). The results of this study are summarized as follows: According to the results of the consumer preference evaluation of low-sodium Korean food, overall acceptability of all menus was over five out of nine points (overall average 6.25). Overall acceptability was highest for grilled beef ribs (7.88), followed by bulgogi (7.63), sauteed dry anchovy (7.46), and simmered beef in soy sauce (7.45). On the other hand, overall acceptability was lowest in blanched and seasoned spinach (5.04). According to the results of Pearson's correlation analysis, overall acceptability was positively related with menu preference of 27 menus, including seasoned and simmered chicken (P<0.001), fiddledhead namul (P<0.001), and grazed lotus roots and burdock (P<0.001). To sum up, overall acceptability of all items used in the consumer preference evaluation was more than five points out of nine. Therefore, low-sodium recipe for Korean food can be effectively applied in commercial or non-commercial foodservice cafeterias.

Objectives: This study was conducted to investigate the effect of low sodium diet education program on dietary habits, diet quality, and measures of obesity in overweight or obese middle-aged women. Methods: Subjects were 81 individuals aged 45 years or over, who completed an 8-week nutrition education. The subjects were divided into a normal group (N = 30) and an overweight-obese group (N = 51) according to the BMI. The effects were evaluated by anthropometric measurement, biochemical analysis, questionnaire, and diet records before and after the program. Results: Overweight-obese group showed significant decreases in weight (p < 0.0001), BMI (p < 0.0001), percent of body fat (p = 0.0087), waist circumference (p < 0.0001), systolic (p = 0.0003) and diastolic blood pressure (p = 0.0261). Nutrients intakes were not different between the two groups and only sodium intake was decreased after education. Total score of general dietary habits, dietary behavior related to sodium intake, dietary diversity score (DDS), diet variety score (DVS), and diet quality index-international (DQI-I) were improved in both groups compared to the baseline. Overweight-obese group showed significant improvement in 'having fruits everyday', 'having fish everyday', 'trying to eat many kinds of food', 'eating less broth when eating soup, stew, and noodles', 'eating less kimchi and salt-fermented vegetable', and 'propensity to think that dishes should be pretty seasoned'. In addition, moderation of empty calories food (p = 0.0064) and macronutrient ratio (p = 0.0004) were improved in the overweigh-obese group, but in the normal group, the results did not reach statistical significance. Conclusions: These results suggested that low sodium diet education program may contribute to obesity management by improving diet quality and dietary habits in middle-aged women.

Salt (NaCl) is one of the most important main source of sodium in our diet. However, health concerns related to salt overconsumption have led to an increased demand for salt-reduced food. The objective of this study was to investigate the possibility of the use of fermented soy sauce to reduce the level of salt in foods. The contents of sodium in bean sprout soup and chicken rice porridge prepared with salt were $1.59{\pm}0.05$ and $1.89{\pm}0.03g/L$, respectively. Whereas, the sodium content range of the same samples prepared with soy sauce were $0.38{\pm}0.01-1.54{\pm}0.02$ and $0.37{\pm}0.00-1.44{\pm}0.01g/L$, respectively. Paired difference test between control and various soy sauce samples was used to provide the amount of soy sauce needed to replace salt without changing the overall taste and intensity. The results showed that sodium reduction (22.0-69.3%) could be achieved in tested foods with the fermented soy sauce.

Appreciable radiation exposures certainly were occurred in the reactor burn-up, the nuelear fall-out and the surroundings of nuclear installations with radioactive effluents. Therefore, radioactive nuclides is not only potentially hazardous to workers of nuclear power plants and related industrials, but also the wokers who handle radioactive nuclides in biochemical research and nuclear medicine diagnostics. And in the case of occurring the nuclear accidents, the early medical treatment of radiation injury should be necessary but little is established medical procedures to decontaminate the victims of internal contamination of radioactive nuclides in korea. Accordingly, to achieve the basic data for protective roles and medical treatment of radiation injury, the present studies were carrid out to evaluate the decontamination of uranium by the chemical drugs. The results observed were summarized as follows: 1. The combined treatmet group of sodium bicarbonate and saline with uranyl nitrate injection simultaneously and the dithiothreitol group that was administered 30 minutes after uranyl nitrate injection were increased significantly in the change of body weight than uranyl nitrate-only group (P<0.005). 2. All the experimental groups were increased the fluid intake and urine volume on the uranyl nitrate-induced acute renal failure. but the combined treatment group of sodium bicarbonate and saline with uranyl nitrate injection simultaneously and the dithiothreitol group that was administered 30 minutes after uranyl nitrate injection have the higher increment of fluid intake and urine volume (P<0.05). 3. When sodium bicarbonate and saline was treated with uranyl nitrate injection simultaneously. and dithiothreitol was administered 30 minutes after uranyl nitrate injection. there was significantly reduced in BUN concentration (P<0.01). 4. When dithiothreitol was administered 30 minutes after uranyl nitrate injection. there was reduced more significantly on the increment of serum creatinine concentration than that observed in uranyl nitrate-only group(P<0.01). but when the combined treatment of sodium bicarbonate and saline with uranyl nitrate simultaneously, there was still. albeit much less marked. decrease in serum creatinine concentration. 5. The sodium bicarbonate and saline was treated with uranyl nitrate simultaneously and dithiothreitol was administered at 30 minutes after uranyl nitrate were excreted markedly higher urine creatinine concentration than the uranyl nitrate-only group. 6. Uranyl nitrate has been used in experimental animals to produce hydropic degeneration and swelling of proximal tubules, disappearance of microvilli and brush border or necrosis in the kidney and centrilobular necrosis, congestion, and telangiectasia of the liver. When the sodium bicarbonate and saline was treated with uranyl nitrate simultaneously, and dithiothreitol was administered. 30 minutes after uranyl nitrate, there was more marked the protective effect than uranyl nitrate-only group. Finally, if the sodium bicarbonate and saline may administered as quickly as possible each time that some risk for internal contamination, with uranium, and dithiothreitol is administered 30 minutes after uranium contamination, there ameliorates the course of uranyl nitrate-induced acute renal failure.and this effect is assocciated with prevention of uranium (heavy metal)-induced alterations in BUN, serum creatinine, urine creatinine, fluid intake, urine volume and body weight.

Although there have been diverse opinions, permanent anticoagulation is generally recommended in children with mechanical valves. We experienced the thrombotic dysfunction of mitral St. Jude Medical valve in a 4-year-old child who had been under control of anticoagulation with warfarin sodium. Besides the primary problems related to the prosthetic mechanism, various patient factors might have contributed to the valve thrombosis. We would emphasize the necessity of anticoagulation and the close observation for valve dysfunction in pediatric patients with St. Jude Medical valve in mitral position.

Spasmodic dysphonia is a task-specific dystonia affecting the laryngeal muscles, resulting forced, strained voice. The pathophysiologic mechanism is not fully understood. We experienced a patient with epilepsy developed transient spasmodic dysphonia during valproic acid monotherapy. The spasmodic dysphonia resolved with dose reduction of valproic acid. Change of neurotransmitters, such as GABA in basal ganglia or blockade of sodium channel is possible mechanism in our case of drug-related spasmodic dysphonia.

The composition and the microstructure of the lead-tin alloy electrodeposited in a gluconate bath were invesitigated according to electrolysis conditions. The tin content of the lead-tin alloy electrodeposits increased with increasing current density and EDTA addition, while it decreased with increasing temperature and sodium gluconate concentration. The preferred orientation of the alloy deposits changed from the (220) plane through (200) to (200) + (111) planes with increasing cathode overpotential. The surface morphology of the films was closely related to both the preferred orientation and the alloy composition.

The complex formation constants (${\beta}_{MLn}$) of potassium and various sodium-selective neutral carriers in solvent polymeric membranes have been determined using solvent polymeric membrane-based optodes and ion-selective electrodes (ISEs). Two different types of PVC-based membranes containing the H^+selective chromoionophore (ETH 5294) with and without a sodium ionophore (4-tert-bntylcalix[4]arenetetraacetic acid tetraethyl ester, ETH 2120, bis[(12-crown-4)methyl] dodecylmethylmalonate or monensin methyl ester) were prepared and their optical responses to either the changes in alkali metal cation (e.g., sodium and potassium) concentrations at a fixed pH (0.05 M Tris-HCl, pH 7.2) or varying pH at a fixed alkali metal cation concentration (0.1 M) were measured. The same type of membranes were also mounted in conventional electrode body and their potentiometric responses to varying pH at a fixed alkali metal cation concentration (0.1 M) were measured. The complex formation constants of the ligand could be calculated from the calibration plots of the relative absorbance vs. the activity ratios of cation and proton ($a_{M^+}/a_{H^+}$) and of the emf vs. pH. It was confirmed that the ratio values of the complex formation constants for the primary and interfering ions are closely related to the experimental selectivity coefficients of ISEs.
