About Oui-Ga-Sil(胃家實) in order to considerate the contents recorded in Nai-Gyung Sang-Han-Lon and latter literature, definition, etiopathology, syndrome, differential diagnosis, therapy, Prognosis and prevention were classified. And the results were as follows: 1. Oui-Ga(胃家)was a term which indicated the whole digestive system such as stomach, small intestine, large intestine, rectum and anus. Sil(實)could be defined as the peculiar concept pertaining to the acute and last stage which was invaded to inside bowels because of abundance with evil influence. 2. Eliology of Oui-Ga-Sil was abunt gastric fever originally, injured mucus because of mistreatment, the invasion to inside of outside evil influence through meridian. Pathology was the opening and shutting appearance of gastric abundance with intestinal emptiness, and intestinal abundance with gastric emptiness, Oui-Ga-Sil could be occurred because of gastric abundant dryness and splenic humidifying capacity decrease. 3. Symptom of Oui-Ga-Sil was classified as for the sunlight outside syndrome and the inside abundant syndrome. The sunlight outside syndrome was body fever, sweating, no chilling, on the contrary hatred of fever. The chief complaint of inside abundant syndrome was daily fever, talking in delirium, hand and foot sweating, abdominal distention, difficult defection and those could be pertained to sunlight bowel syndrome. 4. Diagnostic views of Oui-Ga-Sil were that pulse was descending abundant large strong and smooth quick, a coated tongue was yellow, deep yellow, old yellow, thick, scorching dry rough or gray black. On abdominal diagnosis, pressing by hand, patient was conscious of pain, excessive pain, rejection against press, impossible press or intermittent abdominal pain and bowel cutting pain without press. 5. Differential diagnosis was that the sunlight of Nai-Gyung-Fever-Theory was outside desease making meridian the prime object, Baik-Ho-Tang syndrome was making figureless abundant fever the pivotal point. And important differential standard of splenic shrink syndrome was that a daily fever, an irritation with fever were not occurred. 6. Theory of Oui-Ga-Sil was that Seng-Gi-Tang classes had been used in attacking downward or making balance, and moxibustion on Jung-Wan, honey boiling induction theory had been also used. Attacking downward therapy was invigorating method to preserve mucus, and if mucus had been exausted with complicating emptiness prognosis had been appeared badly. 7. Preventing from Oui-Ga-Sil diet by rule, fitness to cold and warmth may be needed to prevent outside evil influence attack and inside evil influence occurrence. Prudence with being very busy, fatigue, wine and woman may be also needed not to be an injury to splanic and gastric spirit.

The biological activities of Smilax china L. rhizome (SCR), hot water (SCRW) and 70% ethanol extract (SCRE) were analyzed. The total phenolic contents of SCRW and SCRE were 51.7 and 100.5 mg/g, respectively. The measured flavonoid content of SCRW ($67.7{\mu}g/g$) was almost double that of SCRE ($31.7{\mu}g/g$). SCRE ($IC_{50}=42.4{\mu}g/mL$) exhibited stronger antioxidant activity in the DPPH system than the positive control ${\alpha}$-tocopherol ($71.3{\mu}g/mL$) or butylated hydroxy anisole ($53.8{\mu}g/mL$) did. SCRE ($IC_{50}=50.3{\mu}g/mL$) also showed stronger ABTS radical scavenging activity, as did ${\alpha}$-tocopherol ($67.1{\mu}g/mL$). The SOD-like activity and Tyrosinase inhibition activity of SCRW and SCRE showed almost the same pattern. The best SOD-like activity and tyrosinase inhibition activity were measured as 24.9% and 20.3% in SCRW at $1,000{\mu}g/mL$, respectively. The cytotoxic effects of the SCR extracts were analyzed via MTT assay on human cancer and normal cells. SCRW and SCRE did not show cytotoxicity up to the concentration of $1,000{\mu}g/mL$ against the normal human cell line HEK293. Against human breast cancer cells (MCF-7), SCRW inhibited MCF-7 growth (by 27.6%) better than the anticancer drug cyclophosphamide (15.5%) at $1,000{\mu}g/mL$. SCRE ($1,000{\mu}g/mL$) inhibited the growth of human lung cancer cells A549 (37.6%) and human stomach cancer cells AGS (53.6%) more effective than did SCRW (21.0% and 35.4%) or CPA (22.2% and 31.7%). These results suggest the potential use of SCRE and SCRW as an excellent antioxidant and antiproliferative substance, respectively.

The objective of the present study was to evaluate the protective effect of red ginseng (RG) according to steaming time on 150 mM HCl/60 % ethanol induced gastric ulcer models in mice. The sample was divided into 3 groups-G (dried ginseng), RG 4 (steamed 4 h and dried ginseng), RG 6 (steamed 6 h and dried ginseng), and determined through in vitro experiments, such as 1,1-diphenyl-2-picrylhydrazyl and 2,2'-azinobis-3-ethyl-benzothiazoline-6-sulfonic acid radical scavenging activity, HPLC analysis, total polyphenol, and flavonoid contents. In vitro experiment results were depended on steaming hours. Based on the results, we chose two samples (G, RG 6) and conducted in vivo experiments. Mice were divided into 5 groups: Nor (normal group), Con (acute gastritis mice treated with distilled water), G (gastris induced by HCl/Ethanol treated with 100 mg/kg G), RG 6 (gastris induced by HCl/ethanol treated with 100 mg/kg RG 6), and SC (gastris induced by HCl/Ethanol treated with 10 mg/kg sucralfate). In our results revealed that RG 6 suppressed elevated reactive oxygen species, and inflammatory related makers, such as cyclooxygenase-2, inducible nitric oxide synthase, tumor necrosis factor alpha, and interleukin-1 beta. In addition, gastric lesion area was improved. These results suggest that RG 6 protects the stomach by attenuating oxidative stress and inflammatory response under gastric ulcer conditions. Therefore, RG 6 should be a potential therapeutic agent for the treatment of acute gastric ulcer.

We studied effects of hot water extract of Lentinus edodes (Berk.)sing. and Pleurotus eryngii (De Candolle ex Fries) Quel mushroom on proliferation and apoptosis of the human colon adenocarcinoma, HT-29 and Caco-2.. Cells were maintained with Dulbecco's modified Eagle medium/Ham's F-12 nutrient mixture supplemented with 10% fetal bovine serum at 37$^{\circ}C$ in a humidified $CO_2$. For cell proliferation experiments, cells were seeded in 35 mm dishes, treated with the various concentrations of the extract for the different time course. Apoptosis was measured by caspase-3 activity The more contents of the extract added in HT-29 and Caco-2 were, the more cell proliferation was suppressed. When we incubated HT-29 cells for 24, B\ulcorner72, and 96 hours after treatments, cell proliferation was markedly suppressed after 96 hours. Also, caspase-3 activity in HT-29 was increased by the treatment of Lentinus edodes and Pleurotus eryngii extracts. However, the treatment of the extract to SNU484, Korean stomach adenocarcinoma, did not show any influence on cell proliferation and caspase-3 activity Therefore, Lentinus edodes and Pleurotus eryngii are strongly recommended for the prevention and treatment of colon cancer.

The spawning season, growth and feeding habit of tubesnout, Aulichthys japonicus were examined from the samples collected by a small beam trawl in the Zostera marina belt at the coastal water off Hamduck, Cheju Island, from May 1993 to May 1994. Tubesnout was the dominant species of overall 58 species collected in the study area throughout the year. The larvae and juvenile of tubesnout in the frequency distributions of body length began to appear in the Z. marina belt in March, and adults disappeared after May in the following year. The gonad weight index (GWI) and the condition factor (K) were high from November 1993 to January 1994 for males, while females were high from February to May 1994. Although tubesnout is an oviparous fish, males have the urogenital papilla. These results suggest that they were fertilized between November and January, and then males seemed to be died or move into other places. Females were examined to spawn from February to May. The stomach contents of tubesnout were dominated by copepoda smaller than ca. 1mm, Paracalanus, Oithona, Acartia, Oncaea and Harpacticoidae, accounting for 97% of total food items. The feeding habit of tubesnout did not vary by size. The fishes fed on Calanus, Euchaeta and decapoda larvae larger than ca. 3mm in March and April during the spawning season.

Feeding habits of Liobagrus andersoni were investigated in a tributary of the Namhan river from October 2005 to October 2006. L. andersoni was considered as an entirely bottom-feeding carnivore based on it's stomach contents. Because, the diet of L. andersoni was mainly aquatic insect such as Ephemeroptera, Trichoptera, Diptera. The most important prey was Ephemeroptera species. Small sized individuals (<50 mm SL) fed mainly on small prey organisms such as Baetis. However, larger Ephemeroptera and Trichoptera were heavily selected with increasing fish size. The relative proportion of food items was changed with season. The prey materials were more various at summer and autumn than winter. L. andersoni eaten Ephemeroptera intensively in spring and summer but eaten Trichoptera and Chironomidae in winter. Feeding activity of L. andersoni was started after sunset and was most active at midnight, but the activity was reduced after sunrise and during day period. So it was considered that L. andersoni was a nocturnal stalkers.

Fish field survey, especially fish distribution and their ecological characteristics, was performed in the downstream region of Gyeongan stream during the period of before (June) and after (October) the summer monsoon in 2010. Depending on the characteristics of each site, fyke net or casting net was used for fish sampling. Feeding classification was determined by the analysis of stomach contents. Total number of family and species sampled were 5 and 17, respectively. The dominant family was Cyprinidae (12 species), and relative abundance (RA) of the most dominant species, Lepomis macrochirus and Zacco platypus, was 38% and 24%, respectively. Exotic species and Korean endemic species observed were 3 (423 individuals, RA 44%) and 4 (98 individuals, RA 10%), respectively. Tolerance guild analysis as characteristics of ecological indicators revealed an undoubtedly high percentage (97%), compared to others as reflected by the identification of just one sensitive species. Analysis of trophic guilds showed that L. macrochirus dominated among insectivores (44% RA). The food of L. macrochirus composed of, aquatic insects, benthic invertebrates, zooplankton, Chironomidae, and waterweed. Thus, we determined that L. macrochirus could be classified as insectivores (partially carnivores) in this study. Conversely, Z. platypus consumed Cladocera exclusively, greater than 90% of their feed. We presume that stable isotope analysis would identify the exact position of these species in the food web.

Objectives We aimed to understand etiology, pattern differentiation, treatment principle, and the role of selected herbs in the treatment of Korean herbal medicine for allergic conjunctivitis (AC) in children. Methods We searched relevant literature published up to February 20, 2021 through CNKI, using search formula of (SU= '結膜炎'+'conjunctivitis') AND (SU='儿童'+'小儿'+'少儿'+'幼年') AND (SU='治療'+'中医治療'+'中藥'+'中医藥'+'顆粒'+'胶囊'+'自擬'+'湯'+'丸'+'散'+'方'). Results Among 81 searched studies, 9 randomized controlled trials and 1 case report were selected and analyzed. In all studies included, the efficacy of herbal treatment for AC was confirmed, and there was no evidence that herbal medicine treatment has higher risk of developing side effects compared to conventional eye drop treatment. As an etiology, wind (風邪) was observed the most frequently, and Saposhnikoviae Radix (防風) and Schizonepetae Spica (荊芥) were in frequent use to dispel wind (祛風). As visceral pattern identification, spleen (脾) and lung (肺) were two important keywords, and spleen deficiency (脾虛), dampness-heat in the spleen and stomach (脾胃濕熱), lung qi deficiency (肺氣虛) were main pathologic mechanisms. Else, treatments related to liver (肝) and removing dampness-heat (濕熱) were mentioned next. Conclusions This study is significant in that AC in children, which has a lack of research compared to other allergic diseases, has been studied in the contents of Korean medicine and laid foundation that can be used as basic data in the actual clinical field. Based on this study, it is hoped that clinical data of Korean herbal medicine treatment for childhood AC will be further accumulated.

Objective: Ruminants are completely dependent on their microbiota for rumen fermentation, feed digestion, and consequently, their metabolism for productivity. This study aimed to evaluate the rumen bacteria of lactating yaks with different milk protein yields, using high-throughput sequencing technology, in order to understand the influence of these bacteria on milk production. Methods: Yaks with similar high milk protein yield (high milk yield and high milk protein content, HH; n = 12) and low milk protein yield (low milk yield and low milk protein content, LL; n = 12) were randomly selected from 57 mid-lactation yaks. Ruminal contents were collected using an oral stomach tube from the 24 yaks selected. High-throughput sequencing of bacterial 16S rRNA gene was used. Results: Ruminal ammonia N, total volatile fatty acids, acetate, propionate, and isobutyrate concentrations were found to be higher in HH than LL yaks. Community richness (Chao 1 index) and diversity indices (Shannon index) of rumen microbiota were higher in LL than HH yaks. Relative abundances of the Bacteroidetes and Tenericutes phyla in the rumen fluid were significantly increased in HH than LL yaks, but significantly decreased for Firmicutes. Relative abundances of the Succiniclasticum, Butyrivibrio 2, Prevotella 1, and Prevotellaceae UCG-001 genera in the rumen fluid of HH yaks was significantly increased, but significantly decreased for Christensenellaceae R-7 group and Coprococcus 1. Principal coordinates analysis on unweighted UniFrac distances revealed that the bacterial community structure of rumen differed between yaks with high and low milk protein yields. Furthermore, rumen microbiota were functionally enriched in relation to transporters, ABC transporters, ribosome, and urine metabolism, and also significantly altered in HH and LL yaks. Conclusion: We observed significant differences in the composition, diversity, fermentation product concentrations, and function of ruminal microorganisms between yaks with high and low milk protein yields, suggesting the potential influence of rumen microbiota on milk protein yield in yaks. A deeper understanding of this process may allow future modulation of the rumen microbiome for improved agricultural yield through bacterial community design.

To observe the changes of mucosubstances of the mucous secreting cells, stomach tissues in frog tadpoles at each stage of metamorphosis were fixed in 10% buffered formalin at $4^{\circ}C$, embedded in paraffin, sectioned to 4 $\mu$m thickness and stained with periodic acid-Schiff(PAS) and alcian blue (AB) of pH 2.5 and pH 1.0. The results obtained were as follows: 1. The reactivities of the surface mucous cells, which exhibited strong PAS-positivity and weak alcianophilia at both pH 2.5 and 1.0, were not changed in metamorphosis stages and the intracellular contents of neutral mucosubstances in the surface mucous cells increased significantly in XXIV and XXV stages of metamorphosis. 2. In the foveolar mucous cells, which appear after metamorphosis XXI, the staining reactivities to PAS, AB of pH 2.5 and 1.0 were the same as that of surface mucous cells during metamorphosis and the alcianophilia were stronger at pH 1.0 than at pH 2.5. 3. THe mucous neck cells, which appear after metamorphosis XXIV, exhibited a strong PAS-positive reaction and weak alcianophilia at metamorphosis XXIV but at metamorphosis XXV weak reactivity to PAS and strong alcianophilia at pH 1.0.
