Objectives The aim of this study was to investigate clinical factors of SQD syndrome by tracking plasma gut hormone (active ghrelin, active Glucagon-like peptide-1(GLP-1), pancreatic polypeptide(PP), total peptide YY(PYY)) profiling of pre-post prandial standard meal between SQD group and normal group. Methods A total of 24 adult participants were consecutively recruited on April 2014. They were diagnosed as either by SQD syndrome or normal by Spleen Qi Deficiency Questionnaire (SQDQ). On the experimental day, blood samplings of 2 ml were repeatedly collected at 6 points from 2 groups for measuring plasma levels of gut hormones. At every point, subjective appetite sensations were self-registered. Results & Conclusions 1. There were significantly lower subjective 'Appetite' (p=0.012) and higher 'Satiety' (p=0.012) in SQD group. At each time point, subjective 'Appetite' was significantly lower at 60 min after breakfast (p=0.034) and 'Satiety' were significantly higher at 15 min (p=0.020) and 120 min (p=0.044) after breakfast in SQD group. 2. There were no significant differences in plasma levels of gut hormones (active ghrelin, active GLP-1, PP, total PYY) between SQD and normal group. Also at each time point, there were no significant differences of plasma levels of gut hormones between SQD and normal group. 3. Changes in plasma levels of gut hormones compared to baseline were not significantly different at each time point between SQD and normal group. Plasma PYY levels compared to baseline increased in SQD group following 15 min and 30 min after breakfast but decreased in normal group. 4. Further investigation is needed to construct gut hormone profiling and in this perspective, we can approach evaluation tool on variable appetite in Traditional Korean Medicine (TKM) syndrome in the future.

This paper studied the type and character of the Divinity in Korean shamanism. The study of the Divinity means the hierarchy of shamanism, the relationship between shamanism and divinity, and the comparison between shamanism and divinity. The study of the shamanistic divinity based on Kim Tae - Gon's collection of anthology by Shaman(1971). The Jaesugut was composed of the contents of the gods blessing human beings. The JaesuGut of Seoul vary from 10 to 18 depending on the author. The JaesuGut of Goseong consists of 8 Gut. The essence of the ritual gut is to pray for the peace of the individual by using the world which is not explained by reason and science. It is a reincarnation that reflects the world of experience that is stored in the memory of human being that both reason and science can not explain. And the desire to escape from fear was reflected in Jaesu Gut. Every Jaesu Gut in Seoul and Goseong has a main divinity. This main divinity is attached to the divinity in another Gut and becomes a subordination divinity. It also becomes a subordinate-subordination divinity to the another Gut. The gods of reincarnation are basically taken in the order of national security ${\rightarrow}$ local security ${\rightarrow}$ home security.

Simotang oral liquid (SMT) is a traditional Chinese medicine (TCM) consisting of four natural plants and is used to alleviate gastrointestinal side effects after chemotherapy and functional dyspepsia (FD). However, the mechanism by which SMT helps cure these gastrointestinal diseases is still unknown. Here, we discovered that SMT could alleviate gastrointestinal side effects after chemotherapy by altering gut microbiota. C57BL/6J mice were treated with cisplatin (DDP) and SMT, and biological samples were collected. Pathological changes in the small intestine were observed, and the intestinal injury score was assessed. The expression levels of the inflammatory factors IL-1β and IL-6 and the adhesive factors Occludin and ZO-1 in mouse blood or small intestine tissue were also detected. Moreover, the gut microbiota was analyzed by high-throughput sequencing of 16S rRNA amplicons. SMT was found to effectively reduce gastrointestinal mucositis after DDP injection, which lowered inflammation and tightened the intestinal epithelial cells. Gut microbiota analysis showed that the abundance of the anti-inflammatory microbiota was downregulated and that the inflammatory microbiota was upregulated in DDP-treated mice. SMT upregulated anti-inflammatory and anticancer microbiota abundance, while the inflammatory microbiota was downregulated. An antibiotic cocktail (ABX) was also used to delete mice gut microbiota to test the importance of gut microbiota, and we found that SMT could not alleviate gastrointestinal mucositis after DDP injection, showing that gut microbiota might be an important mediator of SMT treatment. Our study provides evidence that SMT might moderate gastrointestinal mucositis after chemotherapy by altering gut microbiota.

Although there has been a steady increase in the prevalence of food allergies worldwide in recent decades, no effective therapeutic strategies have been developed. Modulation of the gut microbiota composition and/or function through probiotics has been highlighted as a promising target for protection against food allergies. In this study, we aimed to investigate the allergy-reducing effects of a probiotic mixture (P5: Lactococcus lactis KF140, Pediococcus pentosaceus KF159, Lactobacillus pentosus KF340, Lactobacillus paracasei 698, and Bacillus amyloliquefaciens 26N) in mice with ovalbumin (OVA)-induced food allergy. Administration of P5 significantly suppressed the oral OVA challenge-induced anaphylactic response and rectal temperature decline, and reduced diarrhea symptoms. Moreover, P5 also significantly inhibited the secretion of IgE, Th2 cytokines (interleukin (IL)-4, IL-5, IL-10, and IL-13), and Th17 cytokines (IL-17), which were increased in mice with OVA-induced food allergy, and induced generation of CD4+Foxp3+ regulatory T cells. These results revealed that P5 may have applications as a preventive agent against food allergy.

We determined the optimal culture conditions for obtaining the maximum number of intestinal bacteria from the olive flounder Paralichthys olivaceus, and studied bacterial diversity using both culture-dependent and culture-independent methods. Using six culture conditions, mean bacterial numbers were greater than $10^6$ per gram of gut mucus, regardless of the medium. However, the bacterial diversity, based on colony morphology, appeared much higher on Marine agar (MA) and Zobell 2216 agar than on other media. We found eight and 17 cultured bacterial phylotypes with 99% minimum similarity in gut mucus grown on MA and tryptic soy agar, respectively. Furthermore, we used genomic DNA extracted from gut mucus to generate 78 random clones, which were grouped into 25 phylotypes. Of these, six were affiliated with Firmicutes, Actinobacteria, and Verrucomicrobia, and were not found using our culture-dependent methods. Consequently, we believe that Marine agar and Zobell 2216 agar are optimal media for culturing diverse intestinal microbes; we also discovered several novel sequences not previously recognized as part of the gut microbiota of olive flounder.

This study sought to investigate any additive or interactive effects that soy isoflavones may have on the ecosystem of the gut, which is influenced by fructooligosaccharide (FOS) in colon-cancer model rats. Male Sprague-Dawley rats treated with 1,2-dimethylhydrazine were given experimental diets containing 0, 3, 6, or 9% FOS with or without 0.1% soy isoflavone for 12 weeks. In addition to the effects of FOS dosage on the gut ecosystem, dietary supplementation with soy isoflavone reduced the number of colonic aberrant crypts (ACs). The fecal weight, fecal pH, and gut transit time significantly decreased in a dose-dependent manner in rats fed FOS and the fecal concentration of bifidobacteria was higher in rats fed FOS than in control rats. The fecal output of total short-chain fatty acids, acetate, and propionate was significantly increased by the presence of FOS and was negatively correlated with the number of ACs, whereas the fecal output of butyrate showed no significant correlation with FOS dosage. The addition of soy isoflavone to the diet did not result in any significant differences in gut ecosystem parameters. Therefore, we conclude that the suppressive effect of soy isoflavone on ACs was not associated with the intestinal ecosystem, which was significantly altered by the dosage of FOS.

This study aimed to present a mouse model of ovalbumin (OVA) induced allergic diarrhea under a sub-barrier system and investigate the development of gut microbiota in this model. Male BALB/c mice were systemically sensitized with OVA or sham-sensitized with saline, and followed by oral OVA intubation, leading to OVA-specific acute diarrhea. Compared with sham-sensitized mice, sera OVA-specific IgG1 and total IgE in OVA-sensitized mice were dramatically elevated, and the number of mast cells was greatly increased in the jejunum of the OVA-sensitized mice. Principle component analysis of the DGGE profile showed that samples from group of OVA-sensitized mice and group of sham-sensitized mice were scattered into two different regions. Real-time PCR analysis showed that the number of 16S rRNA gene copies of Lactobacillus in the colon of OVA-sensitized mice decreased significantly, while there was no significant difference in the number of Bifidobacterium and total bacteria. In conclusion, OVA-specific allergic diarrhea was successfully induced under a sub-barrier system, and changes of allergic reactions during induction was coupled with changes in gut microbiota, especially the number of colonic Lactobacillus, but the role of gut microbiota in the development of food allergic reactions needs to be further evaluated.

Postlarval and juvenile anchovies Engraulis japonicus were collected using a gape net with wings in the coastal waters of Yeosu in July and August 2015, and their gut contents were analyzed. The size range of the postlarvae was 11.0-24.2 mm (notochord length) and that of the juveniles was 25.1-37.4 mm (standard length). Guts were empty in 64.5% of postlarvae and in 51.7% of juveniles. The dominant prey organisms in the guts of both postlarvae and juveniles were copepoda. Calanoida were important prey organisms for postlarvae and were dominated by nauplii of Paracalanus sp. and Calanus sp. as well as unidentified copepod naupill. Calanoida were also important in the diets of juveniles, whose gut contents were dominated by Paracalanus sp. and Cirripedia. Gut compositions were significantly different (P<0.05) among three body size levels in postlarvae and juveniles. As the body size of the postlarvae and juveniles increased, Calanoida constituted a larger proportion of the gut contents, while the proportion of copepod nauplii decreased.

This study was conducted to confirm amino acids from the filterate of pollen treated by purified enzyme of bee larva gut for improving pollen food. The larva gut enzyme were purified by ammonium sulfate, ethanol and Sephadex gel filtration. The filterate of pollen treated with enzyme purified by ammonium sulfate showed the highest amount of amino acids. The amount of amino acids of the filterate from which the pollen was fermented with natural contaminants is 5.5 times as much as the pollen which was not fermented. The filterate of pollen treated with enzyme of bee larva gut contained eighteen different amino acids as follows : aspartates, glutamate, serine, glycine, histidine, arginine, threonine, alanine, proline , tyrosine, valine, methionine, cysteine, isoleucine, leucine, phenylalanine, lysine and trytophane.

Based on both field and laboratory experiments, seasonal changes in the species composition and abundance of phytoplankton in the gut contents of the jedo venus clam, Protothaca jedoensis, and its feeding selectivity were investigated. The phytoplankton in the gut contents comprised Bacillariophyceae (diatom), Chlorophyceae, Chrysophyceae, and Dinophyceae, of which the diatoms being the most predominant throughout the year. Although the number of species and the abundance of phytoplankton in the sea water were always more diverse and more abundant than in the gut contents, the relative number and abundance were generally similar in the seawater and in the gut contents. In the laboratory experiments, the relative abundances of Coscinodiscus marginatus and Thalassirosira eccentrica were much more higher in the gut contents than any other algal species, while Paralia sulcata, Skeletonema costatum, and Eucampia zodiacus were abundant in order of cell density in the ambient water. These results suggest that P. jedoensis may feed preferably on single algal cell or smaller chains of algal cells.
