This work aimed to investigate the psychobiotic effects of six bacterial strains on the mind and behavior of male Wistar rats. The probiotic (PRO) group (n=7) were rats pre-treated with antibiotics for 7 days followed by 14-day probiotic administration, antibiotics (ANT) group (n=7) were rats treated with antibiotics for 21 days without probiotics. The control (CON) group (n=7) were rats that received sham treatment for 21 days. The six bacterial strains with probiotic properties were mostly isolated from Thai fermented foods; Pedicoccus pentosaceus WS11, Lactobacillus plantarum SK321, L. fermentum SK324, L. brevis TRBC 3003, Bifidobacterium adolescentis TBRC 7154 and Lactococcus lactis subsp. lactis TBRC 375. The probiotics were freeze-dried into powder (6×10⁹ CFU/5 g) and administered to the PRO group via oral gavage. Behavioral tests were performed. The PRO group displayed significantly reduced anxiety level and increased locomotor function using a marble burying test and open field test, respectively and significantly improved short-term memory performance using a novel object recognition test. Antibiotics significantly reduced microbial counts in rat feces in the ANT group by 100 fold compared to the PRO group. Probiotics significantly enhanced antioxidant enzymatic and non-enzymatic defenses in rat brains as assessed using catalase activity and ferric reducing antioxidant power assay, respectively. Probiotics also showed neuroprotective effects with less pyknotic cells and lower frequency of vacuolization in cerebral cortex. This multi-strain probiotic formulation from Thai fermented foods may offer a potential to develop psychobiotic-rich functional foods to modulate human mind and behaviors.

Asian populations are thought to receive significant health benefits from traditional diets rich in soybeans due to high isoflavone contents. However, available epidemiologic data only weakly support this hypothesis. The present study was carried out to assess the pharmacokinetics of isoflavones in South Korean women after ingestion of soy-based foods. Twenty-six healthy female volunteers (20-30 y old) consumed three different soy products (i.e., isogen, soymilk, and fermented soybeans) with different aglycone/glucoside ratios. Plasma and urine isoflavone concentrations were measured by high-performance liquid chromatography (HPLC) after ingestion of one of the soy products. Pharmacokinetic parameters were determined using the WinNonlin program. The area under the curve (AUC) for plasma daidzein levels of the soymilk group ($2,101{\pm}352ng{\cdot}h/mL$) was significantly smaller than those of the isogen ($2,628{\pm}573ng{\cdot}h/mL$) and fermented soybean ($2,593{\pm}465ng{\cdot}h/mL$) groups. The maximum plasma concentration ($C_{max}$) of daidzein for the soymilk group ($231{\pm}44$ ng/mL) was significantly higher than those of the isogen ($160{\pm}32$ ng/mL) and fermented soybean ($195{\pm}35$ ng/mL) groups. The half-lives of daidzein and genistein in the soymilk group (5.9 and 5.6 h, respectively) were significantly shorter than those in the individuals given isogen (9.6 and 8.5 h, respectively) or fermented soybean (9.5 and 8.2 h, respectively). The urinary recovery rates of daidzein and genistein were 42% and 17% for the isogen group, 46% and 23% for the fermented soybean group, and 33% and 22% for the soymilk group. In conclusion, our data indicated that soy products containing high levels of isoflavone aglycone are more effective for maintaining plasma isoflavone concentrations. Additional dose-response, durational, and interventional studies are required to evaluate the ability of soy-based foods to increase the bioavailability of isoflavones that positively affect human health.

Hyperglycemia or high glucose (HG), is the hallmark of diabetes, known to induce oxidative stress, release of chemokines, and cytokines, which confer endothelial cell damage. On the other hand, microbial transformation of organic materials often leads to certain changes in their product structures which could enhance their biological activities. The aim of this study was to investigate the beneficial effects of fermented Gastrodia elata (FGE) in HG induced human umbilical vein endothelial cells (HUVECs) dysfunction. GE, fermented by Saccharomyces cerevisiae, which has an extensive history of safe use, exhibited higher phenolic compounds content than those of Gastrodia elata (GE). The HG-induced production of nitric oxide (NO) and interleukin-8 (IL-8) were significantly attenuated by FGE pretreatment to the cells, in a concentration dependent manner. In addition, FGE showed marked activity in free radical scavenging. These results suggest that FGE possesses beneficial effects in protecting against the oxidative stress, and inflammatory conditions in endothelial cells, caused by HG.

Aims: To determine suitable food textures for videofluoroscopic study of swallowing (VFSS), in order to predict and prevent subsequent aspiration pneumonia in esophageal cancer patients with dysphagia after surgery. Materials and Methods: We evaluated 45 hospitalized esophageal cancer patients who underwent surgery between January 2012 and December 2013. The control group consisted of 43 patients treatmed from January 2010 until December 2011 and were not examined by VFSS. Test foods, which were presented in order of increasing thickness, included thin barium sulfate (Ba) liquid (3 or 10 ml), slightly thickened Ba liquid (3 or 10 ml), a spoonful of Ba jelly, and a spoonful of Ba puree. Results: Patients could most safely swallow puree, followed by jelly. The 3-mL samples of both the thin and thick liquids put patients at risk for aspiration pneumonia, with incidence rates of 13% and 11%, respectively. While 64.4% of patients could swallow all test foods and liquids safely, 35.6% were at risk for aspiration pneumonia when swallowing liquids. Even though >30% of patients were at risk, only 1 (2.2%) in the VFSS group developed aspiration pneumonia, which occurred at the time of admission. Following VFSS, no incidence of aspiration pneumonia was observed. However, aspiration pneumonia occurred in 4 (9.3%) control patients during hospitalization. Conclusions: Postoperative esophageal cancer patients were more likely to aspirate any kind of liquid than solid foods, such as jellies. VFSS is very useful in determining suitable food textures for postoperative esophageal cancer patients.

The purpose of this study was to investigate the perception and utilization of Complementary and Alternative Medicine (CAM) for diabetic patients in Busan. The subjects were 227 patients at two general hospitals (over 400 bed). This study was performed through the interviewing process using questionnaires conducted from January to April, 2010. Of a total of subjects, 109 patients (48.0%) had taken CAM at least one time. The patients used CAM recognized that they were 'auxiliary medicines' (39.4%), 'supplementary health foods' (32.1%) and 'medicines' (19.3%), but inexperienced patients perceived them as 'supplementary health foods' (29.6%), 'unscientific treatment' (22.6%) and 'medicines' (20.2%), It was significantly different between two groups of patients (p < 0.001). The number of CAM types used for the patients was 51. The CAM types were plant foods (64.3%), dietary supplement (23.6%) and animal diets (12.1%). The patients used an average of 5.9 different kinds of CAM and an average of 3.8 years them and paid \93,345 per month. The patients with diabetic complications and for longer morbidity periods used CAM for significantly (p < 0.05) longer periods. The mean effectiveness scores of the patients used CAM were 3.31/5.00 for efficacy satisfaction, 3.58/5.00 for fewer side effects compared to those of oral drugs, 3.60/5.00 for psychological stability, 3.81/5.00 for easiness to use, and 3.06/5.00 for economic satisfaction. Of the patients that used CAM, 55.9% did not consult with doctors about CAM. More than two-thirds of the patients (77.1%) did not feel the need to consult with doctors.

Many patients assume that allergic reactions against foods are responsible for triggering or worsening their allergic symptoms. Therefore, it is important to identify patients who would benefit from an elimination diet, while avoiding unnecessary dietary restrictions. The diagnosis of food allergy depends on the thorough review of the patients's medical history, results of supplemented trials of dietary elimination, and in vivo and in vitro tests for measuring specific IgE levels. However, in some cases the reliability of such procedures is suboptimal. Oral food challenges are procedures employed for making an accurate diagnosis of immediate and occasionally delayed adverse reactions to foods. The timing and type of the challenge, preparation of patients, foods to be tested, and dosing schedule should be determined on the basis of the patient's history, age, and experience. Although double-blind, placebo-controlled food challenges(DBPCFC) are used to establish definitively if a food is the cause of adverse reactions, they are time-consuming, expensive and troublesome for physician and patients. In practice, An open challenge controlled by trained personnel is sufficient especially in infants and young children. The interpretation of the results and follow-up after a challenge are also important. Since theses challenges are relatively safe and informative, controlled oral food challenges could become the measure of choice in children.

In this study, Artemisia capillaris, which has been used as oriental medicine area and folks remedy, was investigated for effective substance (scopoletin) analysis. As an attempt to develop new functional beverage by using medicinal herb, Artemisia capillaris. Therefore we investigate the effect of scopoletin in Artemisia capillaris on vessel and regional cerebral blood flow (rCBF) of rats. Artemisia capillaris extract was significantly decreased vessel constraction and significantly increased rCBF. Artemisia capillaris has often been cited in medical literature for its medicinal effects. Although the Korean Food and Drug Administration indicated Artemisia capillaris as the In-Jin-Sook which was allowed as a food stuff. From the view point of the subjects who eat In-Jin-Sook products, most of them ingested it for a certain pharmacological efficacy rather than as a beverage or a food. According to this facts, we need develop functional foods using In-Jin-Sook. Also scopoletin, get known to smooth muscle relaxation content was 326.13 ug/g. These results demonstrate that Artemisia capillaris has pharmaceutical effects and balanced nutritional contents. In according with Artemisia capillaris has a sufficiency of the terms use of food stuff in functional foods.

Ecklonia cava (EC) has been widely utilized as an ingredient in commercial products such as functional foods and cosmeceuticals. Recently it has been found that Sargassum horneri (SH) has been invading on Jeju Island coast area by its huge blooming. Moreover, both seaweeds are considering as important ingredients in traditional medicine specifically in East-Asian countries (China, Japan, and Korea). In the present study, we attempted to compare anti-inflammatory properties of 70% ethanolic extracts of EC (ECE), SH (SHE), and their different combinations on lipopolysaccharide (LPS)-activated RAW 264.7 cells. Results indicated that 8 : 2 combinations of ECE : SHE significantly inhibited LPS-activated inflammatory responses (cytokines, protein, and gene expression) in RAW 264.7 macrophage cells compared to the respective extracts and other combinations. The synergistic effect of ECE and SHE was found to be prominent than the effects of ECE or SHE alone. These observations provide useful information for the industrial formulation of functional materials (functional foods and cosmeceuticals) using these two particular seaweeds in Jeju Island of South Korea.
