Purpose: Malnutrition is a common feature in critically ill children. Enteral nutrition (EN) is the main strategy to nutritionally support critical ill children, but its use can be hindered by the development of intolerance. The study aimed to assess the effectiveness and safety of amoxicillin/clavulanate (A/C) to treat EN intolerance. Methods: We retrospectively evaluated patients admitted to the pediatric intensive care unit from October 2018 to October 2019. We conducted a case-control study: in the first 6 months (October 2018-April 2019) we implemented the nutritional protocol of our Institution with no drug, whereas in the second half (May 2019-October 2019) we employed A/C for 1 week at a dose of 10 mg/kg twice daily. Results: Twelve cases were compared with 12 controls. At the final evaluation, enteral intake was significantly higher than that at baseline in the cases (from 2.1±3.7 to 66.1±27.4% of requirement, p=0.0001 by Wilcoxon matched-pairs signed rank test) but not in the controls (from 0.2±0.8 to 6.0±14.1% of the requirement, p=NS). Final gastric residual volume at the end of the observation was significantly lower in the cases than in the controls (p=0.0398). The drug was well tolerated as shown by the similar safety outcomes in both cases and controls. Conclusion: Malnutrition exposes critically ill children to several complications that affect the severity of disease course, length of stay, and mortality; all may be prevented by early EN. The development of intolerance to EN could be addressed with the use of A/C. Future prospective clinical trials are needed to confirm these conclusions.

The biological activities of licorice F1 (Glycyrrhiza glabra ${\times}$ G. uralensis) lines (G) were investigated, revealing strong radical scavenging activity targeting 1,1-diphenyl-2-picrylhydrazyl (DPPH) and hydroxyl (${\cdot}OH$) radicals. At a concentration of $100{\mu}g/mL$, most of the licorice F1 lines scavenged DPPH and ${\cdot}OH$ by more than 80%. Gs-1, -2, and -6 can be considered good scavengers of DPPH radical and G-7 have higher antioxidant activity against ${\cdot}OH$ radical. In addition, licorice F1 lines exerted effective anti-microbial activities against Escherichia coli (Gs-12, -17, and -18) and Staphylococcus aureus (Gs-3, -4, -5, -21, and -26). Moreover, Gs-2, - 20, -31, and -32 effectively inhibited the growth of Helicobacter pylori. Among licorice F1 lines, Gs-25 exhibited high anti-inflammatory effects on nitric oxide produced by lipopolysaccharide- and interferon-${\gamma}$-activated RAW 264.7 cells. Furthermore, Gs-1, -12, and -20 inhibited the growth of AGS human gastric adenocarcinoma cells by more than 60% at a concentration of $100{\mu}g/mL$ and Gs-5, -11, -19, and -32 showed inhibitory effects against rat lens aldose reductase ($IC_{50}$ values, 1.69, 6.07, 6.12, and $4.54{\mu}g/mL$, respectively). The total content of glycyrrhizin (1), glycyrrhetinic acid (2), glabridin (3), and isoliquiritigenin (4) in licorice F1 lines was high in Gs-11, -15, and -30. The present study therefore indicated that Gs-2, -26, -31, and -32 of licorice F1 possessing strong anti-oxidative, anti-microbial, anti-inflammatory, anti-cancer, and aldose reductase inhibitory effects may be used as a possible source material for natural health supplements in the future.

Background: Perforation of the esophagus is a deadly injury that requires expert management for survival. The mediastinal contamination with microorganisms, gastric acid, and digestive enzymes results in a mediastinitis that is often fatal if untreated. Material and Method: Between January 1990 and June 2004, 38 patients with esophageal perforation were treated in our hospital. Retrospective review of these cases has been performed. Result: There were 28 males and 10 females. The mean age was 43.84$\pm$18.89 years (range $1{\~}73$ years). Spontaneous rupture was found in $34\%$ of perforations, iatrogenic perforation in $32\%$ and traumatic perforation in $34\%$. Perforation occurred in the cervical esophagus in 8 cases, thoracic esophagus in 29 and abdominal esophagus in 1. In the cervical esophageal perforation, managements were primary closure in 8 and drainage in 2. In the thoracic esophageal perforation, managements were primary closure in 14, resection in 3 and conservative management in 12. The mortality rate was $25\%$ in cervical esophageal perforation and $34.5\%$ in thoracic esophageal perforation. We revealed risk factor of esophageal perforation to be peropertaive septic condition (p=0.005). Conclusion: Most important risk factor of esophageal perforation was preoperative septic condition. Preoperative prompt and aggressive preoperative treatment may improve the survival rate of esophageal perforation.

The Mi-Sa(微邪) of the Excessive Liver-Symptoms belongs to the four symptoms, there are meat in eye, edema in cheek, lack of appetite and diarrhea. 3. The Juk-Sa(賊邪) of the Excessive Liver-Symptoms belongs to the only one symptom, this is nosebleeding. 4. The Hu-Sa(虛邪) of the Excessive Liver-Symptoms belongs to the three symptoms, there are scrotum constraction, strain in belly and constipation. 5. The Sil-Sa(實邪) of the Excessive Liver-Symptoms belongs to the twenty eight symptoms, there are red eye, raised eyes(兩眼上?), spitting blood, sternocostal turgid pain, turgidity in belly, drooping testis, vomiting water acid, sickening, belching, confusion, impatience, frequent forgetfulness, headache, giddness, eye pain, deaf, ringing in the ear, feeling inverse, drying mouth, stuffiness sensation in the chest, chest pain, stuffiness sensation in the belly, bellyache, quadriplegia, spasm of extremities, tremor, alternate spells of fever and chills, high fever and strain in muscle. 6. Those symptoms, Red corner of the eye, red face, swelling on the forehead, stiff-neck and back strong, opisthotonos, constracture of the limbs, vomiting yellow bitter water, speech impediment, epilepsy, depression, strong tongue, different thing in throat, fullness and distention of the gastric region, feeling sick and tenesmus, have no connected with the Excessive Liver-Symptoms(肝實證) 7. The Excessive Liver-Symptoms(肝實證) is connected with the ganjabyoung(肝自病) and Hwa(火) which the pathology is, than because Mock(木) is excessive and Mock-Saeng-Hwa(木生火), the ganjabyoung(肝自病) and Sil-Sa(實邪) are many. 8. There are the sixteen symptoms with the exception of The Excessive Liver-Symptoms(肝實證), because supposed that the scholars in medicine included the union syndroms(合病), the combine syndroms(兼病) and the analysis of symptoms(辨證) in The Analysis of Five Visceral Symptoms. 9. During consideration of the symptoms at the above statements, where are many causes by Gan-Pung(肝風), there is difficult of distinction between the excessive Liver-Symptoms(肝實證) and C.V.A(Cerebral Vascular Attack). Because than NaeKyung(內經) distinguished between the excessive Liver-Symptoms(肝實證) and C.V.A., the future medical specialists connected with the excessive Liver-Symptoms(肝實證) and C.V.A.. 10. An appearance of Sang-Hwa(相火) that the liver possessed is divided into an appearance of Hwa(火), there will be making a study att the more necessary. 11. The cuases of each syndroms are consist of the origins of syndroms, its pathology and the positions where the syndroms appeared, I consider that is the various ways how judge the syndroms except the Five Pathogenic Factors(五邪). 12. If more than study will be achieved in all, the new definition will be standed about the Excessive and Deficient Five Visceral Syndroms(五臟虛實證), I consider this will be the foundation data that study the Oriental Medicine and the important data that is a judgement standard of clininc.

The primary objective of this study was to select a probiotic starter for cheonggukjang using 60 strains isolated from rice straw. Among isolated strains, only 8 strains including strain B-59 evidenced proteolytic, amylolytic and soybean activity. These 8 strains were all gram-positive, spore-forming rods. The B-59 strain evidenced antimicrobial activity against Staphylococcus aureus, Listeria monocytogenes, Pseudomonas fluorescens, and Vibrio parahaemolyticus. The antimicrobial activity of isolated B-59 was verified by its ability to inhibit the growth of S. aureus, L. monocytogenes, P. fluorescens, and V. parahaemolyticus. The selected B-59 strain was indentified as Bacillus licheniformis, as shown by a result of 99.0% homology upon API kit analysis. The selected B-59 strain also displayed viability in pH 2.5 artificial gastric juice, artificial bile acid, NaCl (2, 4, 8, 16, 32%), and ethanol (4, 8, 16, 32%). The antioxidative activity of the strain B-59 culture was assessed via a DPPH free radical scavenging activity assay. The activity increased with an increasing in the fermentation time of strain B-59 for 20 hours.

Biphenyldimethyldicarboxylate (PMC), which has been used to treat hepatitis, is insoluble in water, therefore it has low bioavailability after oral administration. For the purpose of increasing the dissolution rate of PMC, the physical mixtures and inclusion complexes of PMC and $dimethyl-{\beta}-cyclodextrin\;(DM\;{\beta}CD)\;or\;hydroxypropyl-{\beta}-cyclodextrin\;(HP{\beta}CD)$ in molar ratio of 1 : 1 and 1 : 2 were prepared by solvent evaporation method. Mixed micelles of PMC were prepared by reacting PMC with bile salts [sodium cholate(NaC), sodium glycocholate (NaGC)] and oleic acid (OA) or palmitoylcarnitine chloride(PCC). Chloroform/water partition coefficient (PC) of PMC was 36.14 in artificial gastric juice (AGJ) and 33.47 in artificial intestinal juice (AIJ), respectively, on the other hand octanol/water PC was 63.36. PMC formulation was prepared by reacting PMC with PEG400-glycerin system(95 : 5, 90 : 10, respectively) and PEG400-PEG4000-glycerin system (70 : 25 : 5, 65 : 25 : 10, respectively). Dissolution test was performed in AGJ and AIJ by paddle method at $37{\pm}0.5^{\circ}C$. The dissolution rates of PMC tablets on the market were 5.74% and 8.26% at AGJ and AIJ, respectively and marketed PMC capsules were 22.14% and 28.64% at AGJ and AIJ, respectively. The dissolution rates of inclusion complexes of PMC with $DM{\beta}CD$ and $HP{\beta}CD$ in a molar ratio of 1 : 1 were more fast than those of corresponding physical mixtures. The decreasing order of dissolution rates was as follows; PMC-PEG400-PEG4000-glycerin formulation > PMC-PEG400-glycerin formulation > mixed micelles > CD inclusion complexes. The dissolution rates of PMC-PEG400-glycerin and PMC-PEG400-PEG4000-glycerin formulation were most fast and the percentage of dissolution was almost 100% within 20 minutes. And their dissolution rates after 120 minutes were markedly increased as compared with capsules on the market (4.0-fold and 3.2-fold in PMC-PEG400-glycerin formulation at AGJ and AIJ, respectively, and 4.8-fold and 3.7-fold in PMC-PEG400-PEG4000-glycerin formulation at AGJ and AIJ, respectively).

19 strains, which could be identified as Lactobacillus sp. were isolated. The Cucurbita maxima has been known as a traditional healthy food and variable positive effects on the human body were already reported. In this study we tried to develop a production process for a healthy fermented drink with Cucurbita maxima and strains originated from Kimchi. Many kinds of lacctobacci species existed in the fermented food cannot survive in the acidic conditions in the stomach. So we tried to search and select a strain, which can arrive to the small intestine. A species of a Lactobacillus named as C332 was identifed as Lactobacillus plantarum and selected for the fermentation process. With the treatment with artificial gastric juice and artificial bile the survival rate of the cells could be calculated. The physiological characteristics at the variable conditions have been tested. After fermentation process the sensoric tests on the product with panels were tried. The most of the cells could survive in the acidic conditions and falcultive anaerobe. Especially some antibacterial effects aganinst E.coli were also found. With all kinds of the results from our research the fermented Cucurbita maxima drink can be a successful item in the market.

Objective: Chronic reflux esophagitis (CRE), characterized by esophageal mucosa ulcer, is caused by continuous backflow of gastric acid and consequent inflammation due to unstable gastroesophageal sphincter. The aim of the present study was to clarify the effect of an Arecae Semen and Coptidis Rhizoma mixture (AC-mix) on CRE. Methods: CRE was surgically induced in SD rats with three experimental groups used: normal; CRE control; and CRE treatment (200 mg/kg AC-mix). Blood and esophageal tissue were collected after two weeks of drug administration. The anti-oxidant activity of the AC-mix was measured by total polyphenol and total flavonoid contents as well as by radical scavenging activity with protein levels evaluated using western blotting. Results: CRE damage to the esophageal mucosa was significantly reduced in the AC-mix group as compared with the controls, and administration of the AC-mix was seen to inhibit NF-κBp65 activity. Consequently, the inactivation of NF-κBp65 significantly inhibited inflammatory mediators such as COX-2 and iNOS. Moreover, the anti-oxidant enzyme HO-1 significantly increased through activation of the Nrf2-Keap1 pathway. Matrix metalloproteinase-2 (MMP-2), which can break down collagen from the basement membrane and extracellular matrix, was decreased following AC-mix treatment, and elevated levels of MMP-2 were regulated by its tissue inhibitor. Conclusions: These results show that AC-mix can alleviate esophageal mucosa ulcer though inhibition of the NF-κBp65 inflammatory pathway and enhancement of the anti-oxidant Nrf2-Keap1 pathway.

There are too many kinds of esophageal corrosive agents, such as sodium hydrochloride, acetic acid, hydrochloric acid, etc. Esophageal burn due to above chemical agents are decreasing recently, but still many patients visited to the hospital because of swallowing corrosive agents for the purpose of suicide or accidentally. Among the treatment of corrosive injury of the esophagus, prevention of esophageal stricture is the key point. Recently various methods are using as the treatment of corrosive esophagitis and prevention of esophageal stricture. 51 cases of corrosive injury of the esophagus who had been admitted and treated at the Dept. of Otolaryngology, Han Yang University Hospital during past 9 years (from May 1972 to Dec. 1980) were evaluated and report the result about age distribution, sex incidence, monthly distribution, cause of swallowing, swallowing agents, arriving time at hospital after swallowing, changes on oral and pharyngeal mucosa, laboratory findings, emergency treatment and treatment during admission, treatment follow up results and complications with review of liter ature. Following results were obtained; 1. Female patients 27 cases (52.9%) were more than male patients 24 cases (47.1%) and its ratio was 1.13 : 1. 2. Age distribution showed predilection for age of 21-30 with 20 cases(39.2%), and 11-20 with 11 cases (21.6%), 31-40 with 7 cases(13.7%), over 50 with 7 cases (13.7%) were following. 3. Monthly distribution showed predilection for March with 8 cases(15.7%), and April, July with 7 cases (13.7%), September with 6 cases(l1.8%), October 5 cases(9.8%) were following. 4. For the purpose of suicide was the most cause of swallowing with 40 cases(78.4%), and accidentally swallowing 11 cases(21.6%). 5. Acetic acid was the most swallowing agent with 24 cases (47.0%), and hydrochloric acid 11 cases (21.5%), lye 8 cases(15.7%), iodine 2 cases(3.9%) were following. 6. Arriving time at the hospital after swallowing showed predilection for within 12 hours with 42 cases (82.4%), and from 12 hours to 24 hours with 4 cases(7.8%) was next. 7. Moderate change with injection and swelling was the prevalent change on oral and pharyngeal mucosa with 20 cases(39.2%) and severe cases with ulceration 18 cases (35.3%), mild cases with injection 10 cases (19.6%) were following. 8. Leukocytosis was seen on 40 cases (78.4%), and increased Hct. was seen 31 cases (60.8%). On urine analysis, 14 cases(27.5%) showed over 1.030 S.G., and proteinuria was seen on 25 cases(49.0%), glycosuria was seen on 5 cases(9.8%) and hematuria was seen on 6 cases(11.8). 9. Gastric lavage was done on 30 cases (58.8%) as emergency treatment and on 3 cases(5.9%) tracheostomy was done for the airway keeping. 10. As methods of treatment during admission, L-tube insertion was done on 50 cases (98.0%), antibiotics was given to 49 cases (96.1%), steroid and antacid were given to 46 cases(90.2%). 11. 36 cases(70.6%) were in favorable condition after proper treatment, but 2 cases (3.9%) were expired during admission, 4 cases (7.8%) showed esophageal stricture in-spite of treatment, and 1 case(2.0%) showed pyloric stenosis. 12. Complications were observed in 8 cases (17.7%). Renal failure (4 cases), aspiration pneumonia (2 cases), upper G-I bleeding (1 cases), and diabetic coma (1 cases) were seen in order of frequency.
