A 3-year-old male lion at Gwangju Uchi Zoo presented for acute onset of haemorrhagic diarrhea and died. The lion showed reddening of the anus as the cause of haemorrhagic enteritis. Necropsy revealed a severe haemorrhagic colitis. Grossly, lesions included icterus, excess pericardial fluid. dark kidneys, and an enlarged, friable liver. The intestines were flaccid, thin-walled, dilated, and 9as-filled. The spleen was enlarged and pulpy because of congestion. Most of organs were rapidly postmortem autolysis. Histopathologically, the intestines were edema and transient leukocyte infiltration of the lamina propria, followed by necrosis. Especially of the intestinal submucosa was edematous, haemorrhagic, or filled with leukocytes. The crypts remained intact or dilated. C perfringens was isolated from a lion at bloody feces, and identified C perfringens type A, confirming the presence of C perfringens $\alpha-toxin$ by PCR. These results were suggested that the case were diagnosed as enterotoxicosis in the lion. More studies are needed on lion enterotoxemia. especially of its etiopathogenesis, in order to develop more efficient prevention for this disease.

An epidemiological survey of human enterobacterial infections was conducted to determine the prevalence of enteropathogens in the Republic of Korea during one year, 2003. We tested for infectious diseases in 26,992 stool samples obtained from people who visited clinics located in six big cities and six rural provinces. From these samples, we isolated 1,291 cases of enteritis bacterial infection (4.8%). In the urban areas, 821 cases of bacterial infection (6.4%) were identified and, in the rural areas, 479 bacterial strains (3.3%) were isolated. Seasonal patterns were seen for diarrhea associated with S. aureus, S. coli and V. parahaemolyticus, while Salmonella and Shigella infections showed slight seasonal variation. We found that S. aureus and Salmonella were more frequently isolated from children and the elderly; however, the prevalence of E. coli, V. parahaemolyticus, and Shigella were similar in different age groups. Routine monitoring of these infections is considered a worthwhile means by which to elucidate their epidemiology and modes of transmission and ultimately to control them more effectively. Continuous laboratory-based surveillance for findings of enteritis bacterial infection should be emphasized in the prevention of these infections.

Since germanium has been shown to be beneficial for the treatment of diseases such as cancer and rheumatic arthritis, we developed an adapted process of bio-germanium preparation using inorganic germanium. In the present study we determined the optimal conditions for culturing yeast Saccharomyces cerevisiae (KCTC-1199), and the best concentrations of inorganic germanium for the adaptation process. The resulting method was successful at producing high quantities of germanium yeasts. The following are the culture conditions that obtained the highest level of productivity: an inorganic germanium concentration of 3,000-5,000 ppm, a pH of 6.5, a temperature of $35^{\circ}C$, and 20 hr of incubation time. In addition to this high-yield quantity study, we observed the acute oral toxicity of mice treated with Geranti Bio-Ge $Yeast^{(R)}$. We found no changes in body weight, or in the mortality between the control groups and the bio-germanium yeast group. There were also no digestive problems such as diarrhea that occurred in either group.

After the introduction of cyclosporin, the graft survival rate of renal transplant and patients' life expectancy have been greatly improved. However, cyclosporin is known to cause several undesirable side effects, one of which is hyperuricemia, which may subsequently cause gouty nephropathy and graft dysfunction. The purpose of this study was to evaluate the frequency and predisposing factors of hyperuricemia in cyclosporin-treated patients within one year of kidney transplantation and uricosuric efficacy of benzbromarone. The patients who were treated with cyclosporin after kidney transplantation in 1998 and the patients who were treated with benzbromarone for the control of cyclosporin-induced hyperuricemia in 1999 were investigated retrospectively. Among the 76 patients in cyclosporin-treated patients in 1998, hyperuricemia occurred in 55 patients $(72.4\%)$ and the mean time from kidney transplantation to occurrence of hyperuicemia was $5.0\pm8.0$ months. In 1999, 22 patients were treated with benzbromarone for hyperuricemia and their mean time from kidney transplantation to occurrence of hyperuricemia was $4.5\pm10.4$ months. Acute rejection developed in one patient $(4.8\%)$ out of 21 normo-uricemic patients and 11 patients $(20.0\%)$ out of 55 hyperuricemic patients in 1998. The difference of rejection rate in these two groups was significant (p<0.001). There was no difference of rejection rate between before and after treatment of benzbromarone. Cyclosporin trough levels did not show a significant correlation with the serum uric acid levels among the three groups. However, hyperuricemic patients showed significantly higher serum creatinine levels than patients with normal uric acid levels (p<0.001). Benzbromarone decreased serum uric acid levels from $8.3\pm2.3\;mg/dl\;to\;5.1\pm2.0\;mg/dl$ (p<0.0001) and normalizing serum uric acid in all of 22 patients. Except for one patient $(4.5\%)$ who experienced diarrhea, no significant side effect was noted.

BACKGROUND/OBJECTIVES: The 6-23 months for infants is the longest period in the "first 1,000 days" of life. This period is very important for child development, so complementary feeding (CF) practices should be optimized to maximize children's potential for growth and development. The aim of this study was to analyze the CF practices and nutritional status of children aged 6-23 months. SUBJECTS/METHODS: For this cross-sectional study, 392 children aged 6-23 months were selected using stratified random sampling. Socio-demographic data were collected through interviews. CF practices, collected by interviews and repeated 24-hour food recall method, were the timely introduction of CF, minimum meal frequency, dietary diversity and minimum acceptable diet, consumption food rich in proteins and vitamin A. Nutritional status was assessed using the indicators of underweight, wasting and stunting. To analyze the association between socio-demographic indicators and CF with nutritional status, the chi-square test with a confidence interval of 95% was used. RESULTS: Results showed that 39% were exclusively breastfed, only 61% received prolonged breastfeeding and 50% received timely introduction of CF. Minimum meal frequency was met by 74% of subjects, but dietary diversity and minimum acceptable diet were only realized in 50% and 40% of the children, respectively. The prevalence of underweight, wasting, and stunting were 26%, 23%, and 28%, respectively. Age of the child, birth order, birth weight, parents' education level, family size and incidence of fever and diarrhea during the previous two weeks were associated with underweight, while child's birth order, fathers' education level, mother's age, family size, completion of the age-appropriate vaccination and fish consumption frequency were associated with wasting. Age of the child, incidence of fever and acute respiratory infection, and fortified food consumption were associated with stunting. CONCLUSIONS: Suboptimal CF practices and high prevalence of underweight, wasting and stunting were found among children aged 6-23 months old in Aceh. These results highlight the need to improve CF and nutritional status.

Cotoneaster mongolicus Pojark. (CM), in the family Rosaceae is an endemic plant to the Mongolian region (its name: Moнroл чapraй). In Mongolia, Cotoneaster species as a crude drug is mainly used for inflammatory diseases, diarrhea, and stomach indigestion. In this study, we evaluated the gastro-protective activity underlying mechanism of CM. For in vivo experiments, mice were divided into 5 groups; normal mice (Normal), gastritis mice (Control), gastritis mice treated with sucralfate 10 mg/kg (SC), gastritis mice treated with CM 100 mg/kg (CML), gastritis mice treated with CM 200 mg/kg (CMH). Gastritis was provoked by HCl/ethanol (60% ethanol in 150 mM HCl). After oral administration of each drug, HCl/ethanol was orally administered 90 mins later to induce gastritis. CM alleviated the damage to the gastric mucosa caused. As a result of confirming the expression of protein in gastric tissue through western blot, CM significantly reduced the expression of NF-κB activated due to gastritis. Also, it significantly modulated the Nrf2-Keap1 pathway. These results indicate that CM not only inhibits the nuclear metastasis of NF-𝛋B but also modulates the Nrf2-Keap1 pathway to relieve inflammation of the gastric mucosa.

Giardiasis is widespread all over the world, and it is a disease that causes both acute and chronic digestive symptoms. It is zoonotic disease that affects animals and humans. There are few studies on giardiasis in stray cats due to difficulties in catching and sampling. Therefore, this study evaluated the prevalence of giardiasis in stray cats in the Daejeon city because of increasing interest as zoonotic disease. The specimens were the feces of stray cats captured for the neutering project (TNR) in Daejeon; 30 fecal samples were collected from 2021 to 2022 in each of 5 districts in Daejeon. A total of 150 samples were collected. All samples were tested for giardiasis using the Giardia SNAP kit (SNAP^Ⓡ test, IDEXX Laboratories. Inc., Westbrook, ME). The overall prevalence rate was 46 out of 150 cats (30.7%). By age, 25 out of 71 juvenile cats (35.2%) were positive, and 21 out of 79 adult cats (26.6%) were positive. A total of 19 out of 69 cats (27.5%) with diarrhea were positive, and 27 out of 81 asymptomatic cats (33.3%) were positive. For gender, 38 out of 99 females (38.4%) were positive, and 8 out of 51 males (15.7%) were positive. The positive rate of giardiasis in stray cats was over 30%, which is high compared to other research results. It is necessary to increase the public's awareness of the value of deworming stray cats and the sanitation of people who have come into contact with them.
