Isolation of tubercle bacilli from sputum samples of patients in the field studies by the cetylpyridinium chloride-sodium chloride & sodium hydroxide methods.

A total of 125 sputum specimens, collected in the field, were homogenised, aliquoted in sterile universal containers and randomly allocated to the cetylpyridinium chloride - sodium chloride (CPC-NaCl) method and sodium hydroxide (NaOH) method for culture of tubercle bacilli. After storage for 8 days at ambient temperature in the field laboratory at Thiruvallur, the aliquots were transported to the main laboratory at Madras where they were processed for culture by the respective methods. The yield of positive cultures in the CPC-NaCl (31/125) method was only marginally better than that in the NaOH method (27/125) (95% CI being-3.4 to 9.8%), while the contamination of cultures was significantly less in the CPC-NaCl method (3/125) than in the NaOH method (12/125) (95% CI being 2.2 to 12.2%). As the CPC-NaCl method has advantages over the NaOH method in reducing contamination, in augmenting the yield of positive cultures and also in its simplicity, it can be applied in field studies.

Interrelationship between sodium chloride, sodium bicarbonate, calcium, and phosphorus in laying hen diets.

Three experiments were conducted with Hy-Line W-36 laying hens housed in individual wire cages in open type houses. The first and second experiments were designed to investigate the effects of sodium chloride and sodium bicarbonate fed at two levels of dietary total phosphorus (.30 and .60%). The third experiment was designed to study the interrelationships between age and sodium source. Supplementing sodium chloride at two levels (.37 and 1.11%) did not effect hen performance, except that egg production was better at the lower NaCl. Egg production was greater when .60 rather than .30% dietary phosphorus was fed. Egg specific gravity and egg weight were decreased at the lower dietary phosphorus. The addition of 1.6% sodium bicarbonate in the sodium chloride-free diets was deleterious to hen performance in all experiments. High mortality was observed in both experiments in which hens were fed diets containing high sodium and low chloride. Plasma calcium and phosphorus levels were significantly depressed in hens fed diets containing the lower phosphorus. Blood pH, base excess, bicarbonate, and total carbon dioxide were significantly increased by sodium bicarbonate supplementation, and these values were found to be inversely related to dietary phosphorus levels.

Modeling the growth of Listeria monocytogenes in cured ready-to-eat processed meat products by manipulation of sodium chloride, sodium diacetate, potassium lactate, and product moisture content.

A central composite second-order response surface design was employed to determine the influences of added sodium chloride (0.8 to 3.6%), sodium diacetate (0 to 0.2%), potassium lactate syrup (0.25 to 9.25%), and finished-product moisture (45.5 to 83.5%) on the predicted growth rate of Listeria monocytogenes in cured ready-to-eat (RTE) meat products. Increased amounts of both sodium diacetate (P < 0.11) and potassium lactate (P < 0.001) resulted in significant reductions in the growth rate constants of L monocytogenes. Increased finished-product moisture (P < 0.11) significantly increased growth rate constants. The nfluence of sodium chloride was not statistically significant. The second-order statistical factor for lactate was significant (P < 0.01), but all two-way interactions were not. In general, predicted growth rates exceeded actual growth rates obtained from inoculation studies of four cured RTE meat products (wieners, smoked-cooked ham, light bologna, and cotto salami). The final model will be useful to food technologists in determining formulations that will result in finished cured RTE meat products in which L. monocytogenes is not likely to grow.

Corrosion of dental amalgams in solutions of sodium chloride, sodium sulfide and ammonia.

Specimens were prepared from three different dental amalgams and were immersed in 0.5% aqueous solutions of sodium sulfide, ammonia and sodium chloride. Every month and over a 6-month experimental period the solutions were replaced with fresh electrolyte and were analyzed in an atomic absorption spectrophotometer with respect to their content in silver, mercury, copper, tin and zinc. In sulfide solutions large amounts of tin and mercury were released from the amalgams while none of the other elements could be detected. Copper, tin and mercury were mostly dissolved in ammonia solutions. An increased silver dissolution could also be observed. Zinc was the first element to be released in sodium chloride solutions. After a 4-month immersion, considerable amounts of copper and mercury could also be found in the same solutions.

The effect of phosphate, sodium chloride, sodium nitrite, storage temperature and pH on the growth of enteropathogenic Escherichia coli in a laboratory medium.

The effect of eight phosphates in combination with sodium chloride/nitrite mixtures on growth of mixed strains of enteropathogenic Escherichia coli over a period of 10 weeks at three pH values (5.6, 6.2, 6.8) and at seven temperatures ranging from 10 degrees C to 35 degrees C is reported. All eight phosphates inhibited growth to varying degrees in at least some of the conditions investigated. Instances of inhibition increased with concentration of sodium chloride/nitrite and were more frequent at lower temperatures and pH values.

Effects of the inorganic salts sodium chloride, sodium bicarbonate, and magnesium sulfate upon the growth and motility of Treponema vincentii.

The use of inorganic salt solutions as chemotherapeutic agents in the control of periodontal disease has received considerable attention in the past few years. Although some research has been published on their clinical effectiveness, little is known about their therapeutic activity and bactericidal effects upon oral spirochetes. The present study investigated the effects of varied concentrations of NaCl, NaHCO3, and MgSO4 upon the in vitro growth and motility of Treponema vincentii. Growth determinations were performed using a turbidiometric analysis at 545 nm. Motility was qualitatively studied by direct examination of 200 treponemes in a wet mount specimen. Samples were taken at 24, 48, 72, and 96 hours following inoculation with the treponemes. Concentrations of 0.5 M NaCl, NaHCO3, or MgSO4 totally inhibited the growth and motility of T. vincentii over a 96-hour period. Salt concentrations less than or equal to 0.10 M had little if any effect upon growth and motility. The data support the hypothesis that the bactericidal and antimotility effects of these salts are related more to their concentrations than to the presence of a specific inorganic ion. They also suggest that motility may be a valid indicator of bacterial viability. Before the clinical significance of the results can be ascertained, human studies are needed to establish sulcular salt concentrations which can be achieved with local irrigation and to determine how long bactericidal concentrations can be maintained.

Effect of supplemental sodium chloride, sodium phosphate, or hydrochloric acid in starter pig diets containing dried whey.

Three experiments involving a total of 606 pigs weaned at 23 +/- 2 d of age were used to evaluate the effects of added dietary Na or Cl or both in combination (NaCl) on postweaning performance responses. A basal diet without added NaCl was formulated to 1.20% lysine using a corn-soybean protein mixture with 20% dried whey (C-SBP-DW) and was used in all experiments. The analyzed content of the basal diet for the three experiments averaged .19% Na, .37% Cl, and 1.37% K. In Exp. 1, NaCl was added to treatment diets at 0, .20, .40, and .60% at the expense of corn. The experiment was a randomized complete block (RCB) design conducted in 14 replicates using a total of 336 pigs (six pigs/ pen). The results demonstrated a linear (P < .01) growth response during the 0- to 7-d and a quadratic (P < .08) response during the 8- to 14-d period. Gain: feed ratio improved quadratically (P < .08) for the 0- to 14-d period. In Exp. 2, Na2HPO4 added to the C-SBP-DW basal diet provided supplemental Na levels of 0, .08, .16, and .24% Na to four treatment diets. The experiment was conducted in six replicates in a RCB design using a total of 144 pigs (six pigs/pen). The results demonstrated a linear (P < .05) growth response during the 0- to 7-d period as Na level increased, but not thereafter, and an improved gain: feed ratio (P < .05) for the 0- to 14-d period. In Exp. 3, Cl was added as HCl at 0, .05, or .10% Cl to the basal C-SBP-DW diet. The experiment was a RCB design conducted in six replicates using a total of 126 pigs (five or six pigs/pen between replicates). The results demonstrated a linear growth (P < .01) and feed intake (P < .08) response during the 0- to 7-d and the 0- to 14-d period to increasing levels of Cl. Feed intake also increased for the 0- to 7-d (P < .08), and 8- to 14-d (P < .05) periods. Stool looseness was unaffected by any of the dietary variables in the three experiments. These results suggest that the NRC (1988) recommendations for Na and Cl for young pigs (< or = 10 kg BW) may need to be increased.

Stability of milrinone in 0.45% sodium chloride, 0.9% sodium chloride, or 5% dextrose injections.

The stability of milrinone in 0.45% and 0.9% sodium chloride injections and in 5% dextrose injection in glass and plastic containers was studied. Admixtures containing milrinone 0.2 mg/mL were prepared in three 500-mL glass containers, three 500-mL polyethylpolypropyl copolymer plastic containers, and three 1-L flexible plastic containers of each solution. Milrinone content was determined by high-performance liquid chromatography at intervals during 72 hours of storage at room temperature; one sample of each solution and container type was protected from light. Duplicate assays of each sample were performed, and samples were observed for visual and pH changes. In all samples milrinone concentrations were more than 97% of the initial concentration. No changes in pH or appearance occurred. Milrinone at a concentration of 0.2 mg/mL is stable for 72 hours at room temperature in 0.45% and 0.9% sodium chloride injections and in 5% dextrose injection in glass or plastic containers.

Natriuretic response to acute sodium chloride or sodium bicarbonate infusions in humans.

We compared the natriuretic responses to acute sodium chloride or sodium bicarbonate loading. 2.25 mEq/kg of sodium as sodium chloride, or sodium bicarbonate was infused intravenously in 1 h. Sodium chloride infusion resulted in a gradual increase in urinary sodium excretion (UNaV) for 4 h after starting the infusion, while sodium bicarbonate infusion caused a transient increase in UNaV for the first 2 h followed by a decrease. The amount of sodium excreted over 4 h in the sodium chloride and sodium bicarbonate groups were 20.7 +/- 4.7 and 34.8 +/- 2.3% of the sodium loaded, respectively (p < 0.05). This difference could not be ascribed to divergent responses in glomerular filtration rate, aldosterone, atrial natriuretic peptide, or serum albumin concentration. The difference in UNaV might be caused by the differences in renal tubular handling of chloride and bicarbonate.

UV-induced Lactobacillus gasseri mutants resisting sodium chloride and sodium nitrite for meat fermentation.

Lactobacillus gasseri, one of the predominant lactobacilli in human intestinal tracts, is utilized for probiotics and dairy starter cultures. However, since L. gasseri is relatively sensitive to sodium chloride and sodium nitrite (essential compounds for meat products), it is difficult to utilize this species for conventional fermented meat products. In this study, efforts were directed to generate mutants of L. gasseri resisting sodium chloride and sodium nitrite. UV irradiation of the strain of L. gasseri JCM1131(T) generated several mutants resisting these compounds. A mutant strain 1131-M8 demonstrated satisfactory growth in meat containing 3.3% sodium chloride and 200 ppm sodium nitrite. Although proteins extracted from the cell surface of 1131-M8 were slightly different from those of the original strain, other biochemical characteristics of both strains were indistinguishable. These results suggest that the L. gasseri mutant obtained in this study could be utilized as a starter culture to develop probiotic meat products.

Effect of sodium chloride- and sodium bicarbonate-rich mineral water on blood pressure and metabolic parameters in elderly normotensive individuals: a randomized double-blind crossover trial.

OBJECTIVE: To examine the effect of sodium chloride- and sodium bicarbonate-rich mineral water on blood pressure and parameters of glucose and lipid metabolism in elderly normotensive individuals. METHODS: We examined 21 healthy men and women aged 60-72 years in a randomized, placebo-controlled, double-blind crossover trial. After reducing dietary salt intake to below 100 mmol/day, study participants were randomly assigned to drink 1.5 l daily of a sodium chloride-rich (sodium 84.5 mmol/l, chloride 63.7 mmol/l, bicarbonate 21.9 mmol/l), a sodium bicarbonate-rich (sodium 39.3 mmol/l, chloride 6.5 mmol/l, bicarbonate 48.8 mmol/l) and a low-sodium (placebo: sodium, chloride and bicarbonate < 0.02 mmol/l) mineral water for 4 weeks each in a three-phase crossover order. Each phase was separated by a 2-week washout period in which the study participants remained on a low-salt diet. Compliance was assessed by biweekly urinary electrolyte excretion and five study participants were excluded from analysis for failing to complete the trial or to fulfil the compliance criteria. RESULTS: Mean arterial blood pressure was significantly lower during the periods of consuming low-sodium -7.0 +/- 7.2 mmHg, P < 0.001) or sodium bicarbonate-rich (-5.7 +/- 6.4 mmHg, P < 0.05) water than at baseline. In contrast, blood pressure during the phase of drinking sodium chloride-rich water was identical to that at baseline. Ambulatory 24 h blood pressure, oral glucose tolerance and plasma lipids were not affected by the different regimens. Urinary calcium excretion was significantly reduced by drinking low-sodium or sodium bicarbonate-rich water but was unchanged under the sodium chloride-rich water. CONCLUSION: Consumption of sodium chloride-rich mineral water can abolish the blood pressure reduction induced by dietary salt restriction in elderly individuals. Sodium bicarbonate-rich mineral water in conjunction with a low-salt diet may have a beneficial effect on calcium homeostasis.
