Objectives : This study was aimed at investigating liver protection mechanism of Moschus by inducing liver toxicity through $CCl_4$ in mice and evaluated histological and serological findings. Methods : Experiment groups was categorized into untreated normal group, $CCl_4$ treated control group, and orally administered Moschus experiment group. At the termination of experiment, gross examination of the liver as well as histological findings, and Total protein, Total bilirubin, Direct bilirubin SGOT, SGPT, and ALP contents in the serum were evaluated. Results : 1. For gross examination and histological findings, $CCl_4$ treated control group showed destroyed lobular structure, increased fibrosis, as well as hepatic cirrhosis. For the group treated with Moschus, the lobular structure suffered less damage, and showed lower level of fibrosis and liver cirrhosis compared to the control group. 2. For serum analysis, Total protein were significantly increased in the Moschus experiment group than the control group. 3. Total bilirubin didn't show significant differences between the two groups. but direct bilirubin was significantly increased in the Moschus experiment group than the control group. 4. SGOT, SGPT, were significantly decreased in the normal and Moschus experiment groups compared to the control group. 5. ALP was significantly decreased in the normal group compared to the control group, but Moschus experiment group didn't show significant differences compared to the control group. Conclusion : Taken together, Moschus can be effectively used for recovering the liver functions and further researches must be conducted to verify the efficacies of Moschus bile juice.

Carisoprodol (CSP) is commonly prescribed as a skeletal muscle relaxant. Recently, we encountered 7 suicidal cases in which carisoprodol was detected. We developed a rugged, sensitive, and specific method for the determination of CSP and meprobamate (MPB) by GC and GC/MS. Postmortem blood concentrations of CSP and MPB ranged 22.9-124.4 ,$\mu$g/ml and its metabolite, 26.8-144.5 ,$\mu$g/ml respectively. Among 7 cases studied, Only CSP was ingested in 4 cases and combination of CSP and dextromethorphan was ingested in 2 cases according to the case history and one case was with ethanol. The order of the tissue concentration of CSP and MPB was liver> kidney > brain, and the concentration of MPB was higher than that of CSP in all tissues. The MPB /CSP concentration ratios of urine, bile juice, liver, kidney, brain and blood were 15.7, 4.0, 1.2, 1.4, 1.4 and 1.0 respectively. There was a big difference in concentration of CSP and MPB in 7 cases due to differences in the amount of dose administered and time to death after dosing.

For the conversion of food waste into a good recycling material such as animal feed without antibiotics, thirteen lactic acid bacteria, which can be used as good probiotics for animal feed, were isolated from the intestine and feces in pigs. All isolates showed strong tolerance to high salt (4% of NaCl), acid(pH4.0), and bile juice (0.8% of oxgall). The growth rate was best at $37^{\circ}C$ in all strains. Among the isolates, Lactobacillus plantarum CJY-22, L. brevis CJY-42, L. arizonensis CJY-3, and Pediococcus sp. CJY-41 showed higher and broader spectrum of antimicrobial activities against six different pathogens such as Salmonella, typhimurium. L. plantarum CJY-22 has also grown well at $25^{\circ}C$, making this strain as an appropriate candidate for the fermentation of food waste at room temperature, thus conducting the fermentation process cost-effectively.

In this work, we wanted to develop a probiotic from famous longevity villages in Korea. We visited eight longevity villages in Korea to collect fecal samples from healthy adults who were aged above 80 years and had regular bowel movements, and isolated lactic-acid-producing bacteria from the samples. Isolated colonies that appeared on MRS agar containing bromophenol blue were identified by means of 16S rRNA sequencing, and 102 of the isolates were identified as lactic-acid-producing bacteria (18 species). Lactobacillus fermentum was the most frequently found species. Eight isolates were selected on the basis of their ability to inhibit the growth of six intestinal pathogens (Escherichia coli O157:H7, Salmonella enterica subsp. enterica Typhimurium, Salmonella enterica subsp. enterica Enteritidis, Enterococcus faecalis, Staphylococcus aureus, and Listeria monocytogenes) and their susceptibility to 15 antimicrobial agents. Among these eight isolates, four Lactobacillus fermentum isolates were found not to produce any harmful enzymes or metabolites. Among them, Lactobacillus fermentum isolate no. 24 showed the strongest binding to intestinal epithelial cells, the highest immune-enhancing activity, anti-inflammation activity, and anti-oxidation activity as well as the highest survival rates in the presence of artificial gastric juice and bile solution. This isolate, designated Lactobacillus fermentum PL9988, has all the characteristics for a good probiotic.

The Bacillus KU801 strain, due to its potential in the field of probiotics for animal use, was isolated from chicken feces. Strain KU801 was identified as Bacillus amyloliquefaciens KU801 based on the results of 16S rRNA sequencing. Vegetative and spore cells of B. amyloliquefaciens KU801 were resistant to artificial gastric juice and artificial bile acid. B. amyloliquefaciens KU801 was found to inhibit the production of nitric oxide (NO) and increase the production of Interleukin-1 alpha (IL-1${\alpha}$). DNA damage induced by N-methyl-Ntion of ninitroso-guanidine (MNNG) was significantly inhibited, in a dose dependent manner, by preincubating MNNG together with B. amyloliquefaciens KU801. These results demonstrate the potential use of B. amyloliquefaciens KU801 as a feed additive.

This study was performed to screen and select Lactobacillus strains from chicken feces for probiotic use in animals. Of these strains, strain AU had the highest immunostimulatory effect. Therefore, strain A12 was characterized as a potential probiotic. Strain A12 was tentatively identified as Lactobacillus acidophilus A12, using the API 50 CHL kit based on a 99.9% homology. L. acidophilus A12 was highly resistant to artificial gastric juice (pH 2.5) and bile acid (oxgall). Based on results from the API ZYM kit, leucine arylamidase, crystine arylamidase, acid phosphatase, naphthol-AS-BI-phosphohydrolase, ${\alpha}$-galactosidase, ${\beta}$-galactosidase, ${\alpha}$-glucosidase, ${\beta}$-glucosidase, and N-acetyl-${\beta}$-glucosamidase were produced by strain A12. L. acidophilus A12 showed resistance to several antibiotics (nisin, gentamicin, and erythromycin). The amount of interleukin $(IL)-1{\alpha}$ in $20{\times}$ concentrated supernatant from L. acidophilus A12 was approximately 156pg/ml. With regard to antioxidant activity, L. acidophilus A12 supernatant showed 60.6% DPPH radical scavenging activity. These results demonstrate the potential use of L. acidophilus A12 as health-promoting probiotics.

A six months old, male Shih Tzu dog was referred to the Veterinary Medical Teaching Hospital at Kangwon National University, for lethargy, respiratory embarrassment. Survey radiography revealed enlarged cardiac silhouette due to displacement of gas-filled intestine in the pericardium. Although there were no specific clinical signs, this case was diagnosed as peritoneopericardial diaphragmatic hernia (PPDH) based on the results of positive contrast radiography and thoracic ultrasonograpic findings. In addition, the thickened gall bladder wall observed in ultrasonography, increase of alkaline phosphatase and neutrophils indicated cholecystitis. Two hepatic lobes and gall bladder were severely necrotized and adhere to the diaphragm. Direct reduction of the herniated organs might cause hepatic hemorrhage and bile juice leakage which may induce very poor prognosis. To solve the problems, the adhered organs were dissected with part of diaphragm, and lobectomy with cholecystectomy was performed for prevention of some possible complications including peritonitis. This is case report describing resection of part of diaphragm adhered to herniated organ reduce the risk of possible hepatic hemorrhage during surgical correction of PPDH followed bycholecystectomy and lobectomy.

This study aimed to investigate the physiological characteristics and anti-obesity effects of Lactobacillus plantarum K10. The ${\alpha}-amylase$ inhibitory activity, ${\alpha}-glucosidase$ inhibitory activity, and lipase inhibitory activity of L. plantarum K10 was $94.66{\pm}4.34%$, $99.78{\pm}0.12%$, and $87.40{\pm}1.41%$, respectively. Moreover, the strain inhibited the adipocyte differentiation of 3T3-L1 cells ($32.61{\pm}8.32%$) at a concentration of $100{\mu}g/mL$. In order to determine its potential for use as a probiotic, we investigated the physiological characteristics of L. plantarum K10. L. plantarum K10 was resistant to gentamycin, kanamycin, streptomycin, ampicillin, ciprofloxacin, tetracycline, vancomycin, and chloramphenicol. It also showed higher Leucine arylamidase, Valine arylamidase, and ${\beta}-galactosidase$ activities. Moreover, it was comparatively tolerant to bile juice and acid, exhibiting resistance to Escherichia coli, Salmonella Typhimurium, Listeria monocytogenes, and Staphylococcus aureus with rates of 90.71%, 11.86%, 14.19%, and 23.08%, respectively. The strain did not produce biogenic amines and showed higher adhesion to HT-29 cells compared to L. rhamnosus GG. As a result of the animal study, L. plantarum K10 showed significantly lower body weight compared to the high-fat diet group. The administration of L. plantarum K10 resulted in a reduction of subcutaneous fat mass and mesenteric fat mass compared to the high-fat diet (HFD) group. L. plantarum K10 also showed improvement in gut permeability compared to the HFD positive control group. These results demonstrate that L. plantarum K10 has potential as a probiotic with anti-obesity effects.
