ABSTRACT
Helicobacter pylori infections are a major cause of gastrointestinal disorders, including gastric ulcers, gastritis, and gastric cancer. Triple therapy, using two antibiotics and a proton pump inhibitor, is recommended for the treatment of H. pylori infections. However, antibiotic resistance in H. pylori is an emerging issue. Bamboo salt, a traditional Korean salt made by baking solar sea salt in bamboo barrels, can ameliorate the symptoms of various gastrointestinal diseases. Herein, we compared the anti-H. pylori activity of triple therapy (clarithromycin, metronidazole, and omeprazole), solar salt, and bamboo salt in vivo as a preliminary study. Four-week-old C57BL/6 male mice were inoculated for eight weeks with the H. pylori Sydney Strain 1 (SS-1) and orally administered triple therapy drugs and salts for five days. The transcript levels of the H. pylori-expressed gene CagA and inflammatory cytokines Tnfα and Il-1ß significantly decreased in the bamboo salt treated mice than those in the H. pylori-infected control group. This effect was further enhanced by using triple therapy and bamboo salt together. Solar salt caused modest inhibition of H. pylori-induced inflammation. We also demonstrated the synergistic effects of bamboo salt and triple therapy against H. pylori. Thus, bamboo salt may be a potential candidate agent against the treatment of H. pylori-associated gastritis.

Garlic (Allium sativum) is a potentially beneficial functional food that is extensively grown around the globe. We have investigated the effect of roasted garlic on a dextran sodium sulfate (DSS)-induced intestinal permeability model in mice. Mice were divided into four diet groups: CON, DSS, RG (roasted garlic), and RG + Purple bamboo salt (RGP) in the AIN 93G diet for 3 weeks. All groups except the CON group received 2% DSS in drinking water at the last week of the experiment. DSS groups showed significantly elevated gut permeability levels and decreased tight junction protein expression compared to CON. However, RG and RGP displayed remarkably lower trends of gut permeability, increased tight junction protein expression, increased number of goblet cells than the DSS group in hematoxylin and eosin and alcian blue-nuclear fast red stained colon sections. These results indicate that roasted garlic could prevent gut leakage induced by DSS.

ABSTRACT
BACKGROUND: The inclusion of herbal antibacterial agents in the composition of toothpastes is becoming increasingly popular, due to lower side effects. The present study intended to investigate the antibacterial efficacy of a herbal toothpaste containing Bamboo salt on cariogenic oral bacteria. METHODS: The present double-blinded parallel randomized controlled clinical trial was conducted on 60 dental students (age range: 18-30). Following the baseline saliva sampling, the participants were randomly assigned into the case and control groups, to use the Bamboo salt herbal toothpaste and conventional non-herbal toothpaste, respectively. They were instructed to brush their teeth twice a day using the Bass technique. Saliva sampling was repeated after four weeks. The salivary counts of Streptococcus mutans and Lactobacillus at baseline and 4-week follow-up were determined and presented as the logarithm of colony-forming units per milliliter (log CFU/mL). RESULTS: A significant decrease in salivary Streptococcus mutans and Lactobacillus was observed using both toothpastes (*P < 0.001). The difference between the antibacterial efficacy of two toothpaste types on Streptococcus mutans and Lactobacillus was not statistically significant (P = 0.530, and P = 0.137, respectively). CONCLUSION: Due to the comparable efficacy of the investigated herbal toothpaste with conventional toothpaste, it potentially qualifies as a complementary agent for self-care oral hygiene procedures. TRIAL REGISTRATION: This trial was registered in the "Iranian Registry of Clinical Trials" (IRCT20210414050964N1) on 21/06/2021.

AIMS: To evaluate the effect of natural anticoagulants 6.5% proanthocyanidin (PA) and 25% bamboo salt on push-out bond strength (PBS) of AH Plus and BioRoot RCS to dentin. SUBJECTS AND METHODS: 30 single-rooted extracted human teeth were collected. After establishing the working length samples were prepared up to size F3. 5 ml of 3% NaOCl was used as irrigant during instrumentation followed by rinse with 5 ml of 17% ethylenediaminetetraacetic acid. Samples were randomly divided into groups based on the final irrigation solution: Group I - AH plus sealer group, Ia - Saline group, Ib - PA group, Ic - Bamboo salt (BS) group. Group II - BioRoot RCS group, IIa - Saline group, IIb - PA group, IIc - BS group. After obturation, samples were embedded in self-cure acrylic resin and 2 mm thick root slices were made at coronal middle and apical 3rd. These slices were subjected to PBS testing followed by stereomicroscopic examination for checking the mode of failure. STATISTICAL ANALYSIS USED: Kruskal-Wallis and Dunn's post hoc test. RESULTS: 3% NaOCl significantly decreased the bond strength of AH Plus as compared to BioRoot RCS to dentin (P < 0.05). Both PA and BS were capable of increasing the PBS of AH Plus and BioRoot RCS to NaOCl-treated dentin. CONCLUSIONS: Final irrigation with antioxidants such as PA and BS eliminates the risk of reduced bond strength of sealer to root canal walls, which ensues following the use of NaOCl as an irrigant.
ABSTRACT
Bamboo salt has anti-allergic, anti-inflammatory, anti-oxidant, diabetics, anti-aging, and immune-enhancing effects, which are closely related to anti-cancer effect. The aim of this study was to investigate the anti-cancer effects of Sambou bamboo saltTM (SBS) in melanoma skin cancer in vivo and in vitro models. SBS-administered mice effectively reduced tumor growth and increased survival rate compared with B16F10 cell-inoculated mice without tissue damage, hepatotoxicity, and nephrotoxicity. SBS enhanced levels of immune-enhancing mediators, such as interferon-γ, interleukin (IL)-2, IL-6, IL-12, tumor necrosis factor-α, and IgE in serum and melanoma tissues. Furthermore, SBS enhanced activities of caspases and levels of Bax and p53, whereas decreased levels of Bcl-2. This reduction was a consequence of apoptosis signaling pathway. In conclusion, these results suggest that SBS is a potential substance for cancer therapy. SBS has the potential to be developed either as Korean traditional medicine or as a health functional food for cancer therapy. PRACTICAL APPLICATIONS: In these days cancer is one of the world's largest health problems. Bamboo salt is used as a Korean traditional food or medicine and has beneficial effect on inflammation. We have identified Sambou bamboo saltTM (SBS) is a potential substance for cancer therapy. These insights suggest that SBS can potentially be utilized for health functional foods for cancer treatment as well as improve various cancer diseases such as melanoma skin cancer.

Quality characteristics of chicken emulsion sausage manufactured with various levels of NaCl and 9 times heated bamboo salt (0.3%, 0.6%, 0.9%, and 1.2% respectively) were examined. The pH value of chicken emulsion sausage was increase tendency with increasing amount of bamboo salt, on the contrary in case of NaCl sample were decrease tendency with increasing amount of NaCl. Both before and after heating, redness of chicken emulsion sausage with bamboo salt treatments were upward trend with increasing amount of bamboo salt. water holding capacity (WHC) of 1.2% NaCl sample was significantly higher than 0.3%-0.9% (p < 0.05), but 0.9%, 1.2% bamboo salt samples were significantly higher than 0.3, 0.6 % (p < 0.05). Water loss of 1.2% NaCl and 0.9% bamboo salt samples were significantly lower than other treatment (p < 0.05). Protein solubility values significantly increased amount of bamboo salt and NaCl (p < 0.05), and samples of 0.9% NaCl and 0.6% bamboo salt values show similar values. Cooking yield of samples were increased tendency with increasing amount of NaCl and bamboo salt. Also viscosity values of sample containing 1.2% bamboo salt sample showed higher viscosity than other treatments. These results show that containing 1.2% NaCl chicken emulsion sausage and 0.9% bamboo salt chicken emulsion sausage were similar physicochemical properties. Therefore, bamboo salt is suitable for manufacturing chicken emulsion sausage.
ABSTRACT
BACKGROUND: In endodontic therapy, final irrigation is often done with sodium hypochlorite (NaOCl). This jeopardizes the bond strength between the epoxy resin sealer, used subsequently in obturation and radicular dentin. This study aimed to analyze the effect of natural antioxidants, 6.5% proanthocyanidin (PA) and 25% bamboo salt (BS) on the reversal of NaOCl-induced reduced bond strength of an epoxy resin sealer to dentin. MATERIALS AND METHODS: Thirty-three single-rooted extracted human teeth were randomly divided into three groups based on the final irrigation protocol: group 1 (saline), Group 2 (6.5% PA), and Group 3 (25% BS). The canals were cleaned, shaped, and obturated with gutta-percha and AH Plus sealer. 1.5 mm-thick root slices made from coronal, middle, and apical thirds of the canal were subjected to push-out bond strength (PBS) testing. The data were statistically analyzed using Kruskal-Wallis and Dunn's post hoc test (P < 0.05). RESULTS: 5.25% NaOCl significantly decreased the bond strength of AH Plus to dentin (P < 0.05). Both 6.5% PA and 25% BS were capable of reversing the compromised PBS of AH Plus to NaOCl-treated dentin. CONCLUSION: Final irrigation with antioxidants such as PA and BS eliminates the risk of reduced bond strength of AH Plus to root canal walls, which ensues following the use of NaOCl as an irrigant.
ABSTRACT
BACKGROUND: Dental caries is one of several prevalent oral diseases caused by dental plaque biofilms. This study evaluated the anti-cariogenic effects of a bamboo salt (BS) and sodium fluoride (NaF) mixture on oral bacteria.METHODS: The effects of several mixtures of NaF and BS on acid production, growth, and adhesion to glass beads of Streptococcus mutans, and their anti-cariogenic properties were investigated. The growth of S. mutans was measured according to optical density at 3, 6, 9, 12, 15, 18, and 24 hours after treatment using spectrophotometry at a wavelength of 600 nm, while pH was measured using a pH meter. Adhesion of S. mutans was measured according to the weight of glass beads from each group before and after incubation. Gene expression was measured using real-time polymerase chain reaction. Acid production and growth patterns of S. mutans were compared using repeated measures analysis of variance, followed by Scheffe's post-hoc test. The Kruskal–Wallis test was used to compare adhesion, followed by the Mann–Whitney test. Gene expression in the experimental and control samples was compared using the Student's t-test.RESULTS: Growth, acid production, and adhesion of S. mutans were inhibited in all experimental groups. Expression of gft and fructosyltransferase in S. mutans was inhibited in all groups. A mixture of NaF and BS significantly reduced growth, acid production, adhesion, and gene expression of S. mutans compared with the other groups.CONCLUSION: Results of the present study demonstrated that a mixture of NaF and BS was useful as a mouth rinse in preventing dental caries.

Kimchi was prepared with different types of salts: purified salt (PS), solar salt aged for 1 year (SS1), aged for 3 years (SS3), and bamboo salt (BS). Kimchi inoculated with Leuconostoc mesenteroides P30 (starter kimchi), and control kimchi (non-starter kimchi) were prepared, and stored at - 1 °C for 20 weeks. Titratable acidity values increased slowly and reached 0.96-1.01% (pH 3.73-3.83) at 20 weeks. Proportions of coccus-type lactic acid bacteria (LAB) among total LAB were higher in SS kimchi than PS kimchi. Among non-starter kimchi, the proportions were 44.7, 41.6, 29.7, and 32.1% for SS3, SS1, BS, and PS kimchi, respectively, at 2 weeks, and 11.5, 12.8, 6.7, and 5.8%, respectively, at 20 weeks. SS kimchi had much less yeast counts than PS kimchi. Among starter kimchi, yeasts were detected from PS kimchi at 10 weeks but not detected until 18 weeks from SS1 and BS kimchi and 20 weeks from SS3 kimchi.
ABSTRACT
Bamboo salt is generated by baking bamboo and sea salt and is used as a traditional food or medicine. The aim of this study was to investigate the anti-ageing skin effects of Korean bamboo salt and to compare the antioxidant, anti-ageing and anti-inflammatory effects of various salts, including purified salt, solar salt, bath solar salt, Masada solar salt, 1-time baked bamboo salt (1× bamboo salt), and 9-times baked bamboo salt (9× bamboo salt). Based on the content of mineral elements, pH, OH groups and redox potential amperometric analysis, the 9× bamboo salt showed the most antioxidant components and characteristics compared to the other salts. The in vitro results showed that the 9× bamboo salt could inhibit oxidative damage by hydrogen peroxide (H2O2) treatment in HaCaT keratinocytes, and its effect was better than that of the other salts. In an in vivo experiment, SHK-1 hairless mice were treated with UV (ultraviolet) radiation to induce ageing. The epidermal thickness and epidermal structures were then assessed by phenotypic and histological analyses. The 0.2% 9× bamboo salt- and 1× bamboo salt-treated mice had a thinner epidermis than the control mice, and the sebaceous glands were almost intact with a regular arrangement that was similar to those in the normal group. Compared with the UV-treated group (control group) and other salt-treated groups, the 9× bamboo salt- and 1× bamboo salt-treated groups had higher dermal collagen and elastic fibre content. Fewer mast cells were observed in the 9× bamboo salt- and 1× bamboo salt-treated groups than in the control group. The activities of the skin antioxidant-related enzymes superoxide dismutase (SOD) and catalase (CAT) in the 9× bamboo salt- and 1× bamboo salt-treated groups were higher than those in other groups and similar to those in the normal group, but lipid peroxide (LPO) activity and carbonylated protein levels showed the opposite trends. Furthermore, the 9× bamboo salt- and 1× bamboo salt-treated groups had protein contents similar to those of the normal group. In addition, the 9× bamboo salt and 1× bamboo salt effectively down-regulated the expression of matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) and up-regulated the expression of tissue inhibitor expression of matrix metalloproteinase-1 (TIMP-1), matrix metalloproteinase-2 (TIMP-2), SOD and CAT compared to the other salts at a concentration of 0.2% (pâ¯<â¯0.05). These results suggest that at appropriate concentrations, bamboo salt could prevent skin ageing induced by ultraviolet radiation b (UVB) photodamage.

Bamboo salt (BS) is a traditional Korean food, and has been reported to have anti-cancer, anti-inflammatory, and anti-metastatic effects. However, the anti-atopic dermatitis (AD) activity of BS has not been described yet. In the present study, we examined the preventive effect of BS on AD. The effect of oral administration of BS was tested in a 2, 4-dinitrofluorobenzene (DNFB)-induced AD animal model, by histological analysis, enzyme-linked immunosorbent assay, reverse transcription-polymerase chain reaction, caspase-1 assay, and Western blotting analysis. BS administration reduced the total clinical severity and scratching frequencies, compared with the AD group. In the serum of DNFB-induced AD mice, the levels of IgE, histamine, thymic stromal lymphopoietin (TSLP), interleukin (IL)-5, and IL-13 were significantly reduced by BS treatment. BS significantly reduced the protein and mRNA expression of TSLP, IL-6, and tumor necrosis factor-α in the AD skin lesions. BS markedly reduced the infiltration of inflammatory cells. Furthermore, the activation of caspase-1 was reduced by BS in the AD skin lesions. Our results suggested that BS should be considered as a candidate treatment for allergic inflammatory diseases including AD.

Myeolchi jeotgals (MJs) were prepared with purified salt (PS), solar salt aged for 1 year (SS), and bamboo salt (BS) melted 3 times at 10% and 20% (w/w) concentrations, and fermented for 28 weeks at 15°C. BS MJ showed higher pH and lower titratable acidities than the other samples because of the alkalinity of bamboo salt. Lactic acid bacteria counts increased until 4-6 weeks and then decreased gradually, and were not detected after 20 weeks from MJs with 10% salt. Yeast counts of PS MJs were higher than those of BS and SS MJs. Bacilli were detected in relatively higher numbers throughout the 28 weeks, like marine bacteria, but archae were detected in lower numbers during the first 10 weeks. When 16S rRNA genes were amplified from total DNA from PS MJ (10% salt) at 12 weeks, Tetragenococcus halophilus was the major species. However, Staphylococcus epidermidis was the dominant species for BS MJ at the same time point. In SS MJ, T. halophilus was the dominant species and S. epidermidis was the next dominant species. BS and SS MJs showed higher amino-type nitrogen, ammonia-type nitrogen, and volatile basic nitrogen contents than PS MJs. SS and BS were better than PS for the production of high-quality MJs.

OBJECTIVES: The purpose of this study was to evaluate the effect of a dentifrice containing 1,500 ppm F (NaF) and 2% bamboo salt on dental erosion caused by ingestion of acidic beverages. METHODS: Specimens of extracted bovine teeth enamel were embedded in a resin and polished. Experimental specimens were subjected to one of the six treatments (n=10 per treatment group): the experimental group consisted of 1,500 ppm F (NaF)+2% bamboo salt; 1,500 ppm F (NaF); 1,000 ppm F (NaF)+2% bamboo salt; 1,000 ppm F (NaF); free fluoride+2% bamboo salt; and free fluoride. The specimens were exposed to the experimental dentifrice, an acidic beverage, and artificial saliva. The treated specimens were analyzed using a Vickers surface hardness test and scanning electron microscopy (SEM). Surface hardness and SEM were compared before and after the chemical pH cycling sequences for 12 days. RESULTS: Group 1 (1,500 ppm F+2% bamboo salt) showed the highest surface hardness, followed by group 2 (1,500 ppm F), group 3 (1,000 ppm F+2% bamboo salt), group 4 (1,000 ppm F), group 5 (free fluoride+2% bamboo salt), and group 6 (free fluoride), in that order. Upon observing the surface by SEM, when bamboo salt was used and when the NaF concentration was higher, the enamel was denser and the surface was more highly remineralized. CONCLUSIONS: The use of a higher concentration of NaF and bamboo salt resulted in a higher preventive effect on tooth erosive potential. The addition of bamboo salt to dentifrice containing a high concentration of NaF can contribute to preventing dental erosion.

OBJECTIVES: The aim of this study was to assess the antiplaque and antigingivitis effectiveness of aqueous single-phase and oil-water two-phase mouthrinses, containing bamboo salt, magnolia bark, and Centella asiatica extracts, in Korean adults. METHODS: In this double-blinded clinical trial, a total of thirty-four participants aged over 19 years were randomly allocated to three experimental groups: 1) control group; 2) aqueous single-phase mouthrinse (ASM) group, and; 3) oil-water two-phase mouthrinse (OTM) group. The experimental mouthrinses all contained sodium fluoride, and the ASM and OTM contained additional ingredients of bamboo salt, magnolia bark, and Centella asiatica extracts. For the OTM, 50% essential oil was added to create an oil-water two-phase mouthrinse. A two-week randomized crossover design with a two-week washout period was applied. Following a complete dental prophylaxis, participants were instructed to use the prescribed mouthrinse twice daily for two weeks as an adjunct to their usual mechanical oral hygiene procedures. Pre- and post-experiment clinical examinations were performed to measure the plaque index (PI) and bleeding on probing (BOP) for the full mouth. Paired t-test was applied to compare the intergroup differences for all clinical variables. RESULTS: Compared to the control group, ASM showed a significantly reduced BOP (P<0.05). However, there was no statistically significant difference in the effects of the three mouthrinses on reducing the PI. CONCLUSIONS: The results of this study indicate that the use of an aqueous, single-phase mouthrinse containing bamboo salt, magnolia bark and Centella asiatica extracts could help alleviate gingivitis.

The aim of our experiment was to evaluate the anticancer effect of bamboo salt (BS) on C57BL/6 mice in an azoxymethane (AOM)/dextran sodium sulfate (DSS)-induced colon cancer model. BS, solar salt, and purified salt were evaluated for their protective effects during AOM/DSS-induced colon carcinogenesis in C57BL/6 mice. BS, especially after baking for nine separate intervals (BS9x), suppressed colon carcinogenesis in the mice. BS9x decreased colon length shortening, weight-to-length ratios, and tumor counts. Pathological evidence from histological evaluation by hematoxylin and eosin staining also revealed suppression of tumorigenesis. BS9x lowered serum levels of proinflammatory cytokines (TNF-α, IL-6, and IL-1ß) to close to those of the Normal group. Additionally, BS9x suppressed colon mRNA expression of proinflammatory factors and significantly regulated mRNA levels of the apoptosis-related factors, Bax and Bcl-2, and the cell cycle-related genes, p21 and p53. Additionally, immunohistochemistry showed that BS promoted p21 expression in the colon. Taken together, the results indicate that BS exhibited anticancer efficacy by modulating apoptosis- and inflammation-related gene expression during colon carcinogenesis in mice, and repetition in baking cycles of BS enhanced its anticancer functionality.

Samples of doenjang (a fermented soybean paste) were prepared with different types of salts; purified salt (PS), 3-year-aged solar salt (SS3), 1-year-aged solar salt (SS1), and bamboo salt (BS, 3(rd) processing product). For starter doenjang samples, selected starters comprising two bacilli, one yeast, and one fungus were inoculated, whereas for non-starter doenjang samples, microorganisms present in rice straw were inoculated after enrichment. The doenjang samples were fermented for 13 weeks at 25°C. During the fermentation period, SS and BS doenjang samples showed higher bacilli counts as well as much lower yeast counts than PS doenjang. At 13 weeks, yeast counts of starter doenjang samples were 7.75, 5.69, 6.08, and 4.74 log CFU/g for PS, SS3, SS1, and BS doenjang, respectively. For non-starter doenjang samples, counts were 7.17, 5.05, 5.92, and 4.54 log CFU/g for PS, SS3, SS1, and BS doenjang, respectively. SS and BS promoted growth of bacilli but inhibited growth of yeasts compared with PS. Debaryomyces hansenii was the dominant yeast in PS doenjang, whereas Candida guilliermondii and Pichia sorbitophila were dominant in SS and BS doenjang. In the sensory evaluation, SS and BS doenjang scored better than PS doenjang. In conclusion, SS and BS seem better than PS for production of high-quality doenjang.

This study was carried out to investigate the effects of refined, solar, and bamboo salt on the physico-chemical properties and sensory characteristics of cured pork loin. Moisture, protein, fat, and ash content, lightness, yellowness, cooking yield, and color, juiciness, and tenderness of sensory properties on curing pork loin exhibited no significant differences regardless of the nature of salts. The pH of raw and cooked cured pork loin with added bamboo salt was higher that of other salt treatments. However, the cooking loss, and Warner-Bratzler shear force of cured pork loin with added refined salt was lower than those of solar and bamboo salt pork loins cured. The flavor and overall acceptability scores of treatments with refined salt was higher than those of solar and bamboo salt treatments. The unique flavor of bamboo salt can render it as a functional material for marinating meat products. In addition, the results of this study reveal potential use of bamboo salt in meat curing.
ABSTRACT
Bamboo salt (BS) and soy sauce (SS) are traditional foods in Asia, which contain antioxidants that have cytoprotective effects on the body. The majority of SS products contain high levels of common salt, consumption of which has been associated with numerous detrimental effects on the body. However, BS may be considered a healthier substitute to common salt. The present study hypothesized that SS made from BS, known as bamboo salt soy sauce (BSSS), may possess enhanced cytoprotective properties; this was evaluated using a hydrogen peroxide (H2O2)-induced neuronal cell death rat model. Rat neuronal cells were pretreated with various concentrations (0.001, 0.01, 0.1, 1 and 10%) of BSSS, traditional soy sauce (TRSS) and brewed soy sauce (BRSS), and were subsequently exposed to H2O2 (100 µM). The viability of neuronal cells, and the occurrence of DNA fragmentation, was subsequently examined. Pretreatment of neuronal cells with TRSS and BRSS reduced cell viability in a concentration-dependent manner, whereas neuronal cells pretreated with BSSS exhibited increased cell viability, as compared with non-treated neuronal cells. Furthermore, neuronal cells pretreated with 0.01% BSSS exhibited the greatest increase in viability. Exposure of neuronal cells to H2O2 significantly increased the levels of reactive oxygen species (ROS), B-cell lymphoma 2-associated X protein, poly (ADP-ribose), cleaved poly (ADP-ribose) polymerase, cytochrome c, apoptosis-inducing factor, cleaved caspase-9 and cleaved caspase-3, in all cases. Pretreatment of neuronal cells with BSSS significantly reduced the levels of ROS generated by H2O2, and increased the levels of phosphorylated AKT and phosphorylated glycogen synthase kinase-3ß. Furthermore, the observed effects of BSSS could be blocked by administration of 10 µM LY294002, a phosphatidylinositol 3-kinase inhibitor. The results of the present study suggested that BSSS may exert positive neuroprotective effects against H2O2-induced cell death by reducing oxidative stress, enhancing survival signaling, and inhibiting death signals.
