The normal physiological values of Korean mongrel dogs were studied, comparing them with foreign references, on the basis of control physiological data measured on 110 cases out of the dogs submitted to the experiments in our department. The hemodynamic measurements varied widely between the both limits of reported normal control data, with the mean value of heart rate $140.4{\pm}26.6$/min., and both the systolic and diastolic arterial blood pressures $137.2{\pm}31.7$mmHg and $104.7{\pm}14.4$ mmHg, as well as the venous pressure of $9.11{\pm}2.18$ cm.$H_2O$. Hematologically, the number of red blood cells $4,571,000{\pm}767,000$per cu.mm., the amount of hemoglobin $11.57{\pm}3.74$ gm/dl and the hematocrit $37.3{\pm}7.2$ per cent, were equally the values a little lower than the reported normal means. However, the white blood cells were within the reported normal limits both in number, $10,384{\pm}4,877$ per cu. mm and their differential counts with slightly broader ranges of variation. The platelet count was $149,800{\pm}47,000 $per cu. mm and was also far below the normal, while the coagulation time $9.03{\pm}2.69$min. and the prothrombin time $13.17{\pm}6.52$sec were within normal limits, though a little prolonged. The serum electrolytes, Na $146.6{\pm}10.44$mEq/L.,K $4.46{\pm}0.84$mEq/L., CI $118.3{\pm}7.88$mEq/L. and Ca $11.45{\pm}5.62$mg./dl, and the blood glucose level of $94.9{\pm}31.79$mg./dl were essentially not different from the reported normal values. The serum proteins, total protein $7.15{\pm}1.41$gm/dl., albumin $4.09{\pm}0.77$gm./dl. and globulin $3.18{\pm}0.88$gm/dl. were included near the higher limits of the reported normal levels. The thymol turbidity 0.1-3.04 units were normal in 10 cases, and the cephaline flocculation was within normal range except 2 cases out of 26 dogs, showing two positive in 24 hours. And the nitrogen series, NPN $34.61{\pm}10.29$mg/dl. and BUN $12.77{\pm}6.37$mg./dl. were normal. It may be concluded that from the point of view of hereby measured physiological data compared with the foreign references, the Korean mongrel dogs have a compatible laboratory data with only the special regards to their tendency toward anemia in red blood cell series.

OMH which is known for its properties of recruiting vitality, is composed of Polygonum multiflorum Thunb. and Sesamum indicum DC.. This formula is known to possess the properties of recruiting vitality, blackening white hair and expanding life span. 16-week-old SD-Rats were treated with OMH for 16 days. After 24 hours, the rats were treated with MTX(Mthotrexate is oral administrated for 4 days(1mg/kg/day), in order to lower immunity. Then, These rats were classified in to groups, the N-16 group(not specially tested), the Control group(MTX), the OMH-L group(2.5% OMH+MTX)&the OMH-H group(10% OMH+MTX) and 6 rats were assigned to each group. After 18 hours from MTX treatment the organ index of the rats from each group Thymus and Spleen were measured. The percentage of CD+4, CD8+ T cell were measured and compared by flow cytometer. 1) Rats from the OHM-L&OMH-H group showed higher organ indexes of the Thymus and Spleen compared to the rats from the Control Group. This proves that OMH possesses the properties to mitigate degenerations of immunity($F_{thymus}=20.162,\;F_{spleen}=5.882$, ANDVA, p<0.05). 2) The rats from the two OMH groups showed higher rates of CD4+ T cell counts compared to the control group(F=26.906, ANOVA, p<0.05). CD8+ T cell showed lower rates compared to the Control group, but showed no differences within the two OMH groups(F=1.254, ANOYA, p>0.05). CD4+/CD8+ showed higher rates in the two OMH groups compared to the control group which can be thought as a proof that OMH prevents depression of immune response(F=10.554, ANOVA, p<0.05). In this test 16 week-old rats were used, which can be considered as the middle and prime age of the human being. These rats were treated with OMH which ended up showing properties of mitigating degeneration of immune responses and maintaining T-cell rates within the blood. It was possible to study that OMH possesses the properties to increase immune responses.

This study was performed to evaluate the toxicity of cadmium selenide for a period of 28 days in Sprague-Dawley rats. Each of 10 healthy male and females rats per group received daily oral administration for 28-day period at dosage levels 30, 300 and 1,000 mg/kg of body weight. Mortality and clinical signs were checked, and body weight, water intake and food consumption were also recorded weekly. There were no dose-related changes in food consumption or urine volume. All animals survived to the end of study with no clinical signs or differences in body weight gain observed when compared with the control group. At the end of study, all animals including control group, were subjected to necropsy. Blood samples were collected for hematology tests including coagulation time and biochemistry analysis. Blood coagulation time and relative organ weight were unaffected by all received doses. White Blood Cell (WBC) counts significantly increased in the 300 mg/kg administered male animal group when compared to the control. Monocyte (MO) value were also increased significantly in both 300 and 1,000 mg/kg male animal group. However, Mean Corpuscular Volume (MCV) were significantly decreased compared with the control in the 1,000 mg/kg dose groups for male and female animals. Mean Corpuscular Hemoglobin (MCH) decreased significantly for female in the 300 and 1,000 mg/kg group compared to the control. Blood biochemical values of Inorganic phosphorus (IP) were significantly increased in both the 300 and 1,000 mg/kg dose groups in male animals when compared to the control. Creatinine (CRE) levels indicated significant increase in kidney function for the female, 30 mg/kg dose group when compared with control. There was a significant decrease in thymus absolute organ weight in the female, 1,000 mg/kg dose group when compared with control. Histopathological findings revealed no evidence of injury related to cadmium selenide except for one case of focal hepatic inflammation in the high dose (1,000 mg/kg) group. One case of lung inflammation was also seen in the control group. Basis on these result, the No Observable Adverse Effect Level (NOAEL) of cadmium selenide was determined to be more than 1,000 mg/kg/day for male and female rats under conditions in this study.

Homozygous mutations in NUDT15 R139C are known as the major factor associated with thiopurine-induced early leukopenia, particularly in Asian patients. Therefore, NUDT15 genotyping is currently recommended before thiopurine treatment to identify patients who are NUDT15 poor metabolizers and consider the use of an alternative immunomodulatory therapy. We report a case of a 12-year-old Korean girl with Crohn's disease (CD), in whom thiopurine-induced leukopenia was prevented by initiation of azathioprine (AZA) therapy at a low dose (0.5 mg/kg/day) and early detection of significant hair loss and white blood cell (WBC) count decrease at 17 days from the start of AZA treatment. The WBC count dropped from 8,970/μL to 3,370/μL in 2 weeks, and AZA treatment was stopped because of concerns of potential leukopenia in the near future. Her WBC count recovered to 5,120/μL after 3 weeks. Gene analysis later revealed that she had a homozygous mutation in NUDT15 R139C, resulting in a poor metabolizing activity of NUDT15. In situations when NUDT15 genotyping is unavailable, initiation of AZA therapy at 0.5 mg/kg/day with close observation of hair loss and WBC counts within 2 weeks may be an alternative way to prevent thiopurine-induced early leukopenia in Asian children with CD.

Background: This study was designed using a mouse model of atopic dermatitis [phthalic anhydride (PA)-treated mice], to investigate the anti-inflammatory effect of bee venom pharmacopuncture (BVP) in keratinocytes. Methods: Western blot analysis was performed to investigate inflammation related protein expression of iNOS, COX-2, phospho-ERK (p-ERK), and ERK, in LPS (1 ㎍/mL)-activated keratinocytes, following BVP treatment, and in PA-treated mice, after BVP treatment. Griess reaction was performed to investigate NO concentration. Enzyme-linked immunosorbent assays were used to determine the concentrations of interleukin (IL)-4+, IL-17A+, IL-13 and IL-4 in PA-treated mice after BVP treatment. In addition, monocyte, macrophage, neutrophil, and eosinophil counts were measured to observe the changes in white blood cell infiltration. Results: The keratinocytes of the BVP-treated group showed a decreased expression of iNOS, COX-2, ERK at 5 OX-2, ERK E, and p-ERK at 1, 2 and 5 RKRK ERK ERK, and a dose-dependent decrease in NO concentration at 2 and 5 ntrationof s. In the BVP-treated groups (0.1 μ.1-trea μ.1-treated gr), PA-treated mice showed recovery after 4 weeks which was dose-dependent, showing a significant decrease in clinical scores for AD, and a decreased concentration of IL-13 and IL-4 with BV treatment. There was a dose-dependent decrease in the infiltration of eosinophils, neutrophils, monocytes, macrophages, and a decreased thickness of the epidermis due to inflammation, and decreased expressions of iNOS, COX-2, p-ERK, ERK, especially in the 0.1 μ0/mL BVP-treated group, Conclusion: These results suggest that BVP may be an effective alternative treatment for atopic dermatitis.

Objectives: Epidemiological studies have reported that vitamin D deficiency is associated with inflammatory disease. Smoking is a well-known risk factor for inflammation. However, few studies have investigated the interactive effect of vitamin D deficiency and smoking on inflammation. This study aims to investigate the interaction of vitamin D and smoking with inflammatory markers in the urban elderly. Methods: We used data from the Korean Elderly Environmental Panel Study, which began in August 2008 and ended in August 2010, and included 560 Koreans ${\geq}60$ years old living in Seoul. Data was collected via questionnaires that included items about smoking status at the first visit. Vitamin D levels, high-sensitivity C-reactive protein (hs-CRP), and white blood cell (WBC) counts were repeatedly measured up to three times. Results: The association of vitamin D and hs-CRP was significant after adjusting for known confounders (${\beta}=-0.080$, p=0.041). After separate analysis by smoking status, the association of vitamin D deficiency and hs-CRP in smokers was stronger than that in nonsmokers (smokers: ${\beta}=-0.375$, p=0.013; non-smokers: ${\beta}=-0.060$, p=0.150). Smoking status was an effect modifier that changed the association between vitamin D deficiency and hs-CRP (interaction estimate: ${\beta}=-0.254$, p=0.032). Vitamin D was not significantly associated with WBC count (${\beta}=0.003$, p=0.805). Conclusions: Vitamin D deficiency was associated with hs-CRP in the urban elderly. Smoking status was an effect modifier of this association. Vitamin D deficiency was not significantly associated with WBC count.

Oregano (Origanum vulgare) is an aromatic herb belonging to the Lamiaceae family. This study evaluated the therapeutic effect of oregano essential oil (OEO) on clinical bovine mastitis caused by Staphylococcus (S.) aureus and/or Escherichia (E.) coli. Thirty-two quarters from 18 lactating cows with subclinical mastitis were selected from a dairy farm and were divided into 4 groups (8 quarters/group): negative control (CON), positive control (GEN) and two OEO-treated groups (OEO-1 and OEO-2). Each group was intramammarily treated with saline, 10 g/tube of gentamicin ointment, and single and double doses of 0.9 mL OEO ointment twice a day for three days, respectively. After the treatments, physical udder conditions were greatly improved in GEN and OEO groups. In CON group, somatic cell counts (SCCs), number of white blood cells (WBC) and bacteria were increased. However, in OEO groups, SCCs and number of WBC were significantly decreased and S. aureus and E. coli were not detected in milk as compared with those before the treatments as well as GEN group. These results suggest that OEO may be a useful alternative to antibiotics for the control of subclinical bovine mastitis caused by S. aureus and/or E. coli.

Purpose: Escherichia coli sequence type (ST) 131, a multidrug-resistant clone causing extraintestinal infections, has rapidly become prevalent worldwide. However, the epidemiological and clinical features of pediatric infections are poorly understood. We aimed to explore the characteristics of ST131 Escherichia coli isolated from Korean children with urinary tract infections. Methods: We examined 114 uropathogenic E. coli (UPEC) isolates from children hospitalized at Chung-Ang University Hospital between 2011 and 2014. Bacterial strains were classified into STs by partial sequencing of seven housekeeping genes (adk, fumC, gyrB, icd, mdh, purA, and recA). Clinical characteristics and antimicrobial susceptibility were compared between ST131 and non-ST131 UPEC isolates. Results: Sixteen UPEC isolates (14.0%) were extended-spectrum ${\beta}-lactamase$ (ESBL)-producers; 50.0% of ESBL-producers were ST131 isolates. Of all the isolates tested, 13.2% (15 of 114) were classified as ST131. There were no statistically significant associations between ST131 and age, sex, or clinical characteristics, including fever, white blood cell counts in urine and serum, C-reactive protein, radiologic abnormalities, and clinical outcome. However, ST131 isolates showed significantly lower rates of susceptibility to cefazolin (26.7%), cefotaxime (40.0%), cefepime (40.0%), and ciprofloxacin (53.3%) than non-ST131 isolates (65.7%, 91.9%, 92.9%, and 87.9%, respectively; P<0.001 for all). ESBL was more frequently produced in ST131 (53.3%) than in non-ST131 (8.1%) isolates (P<0.01). Conclusion: ST131 E. coli isolates were prevalent uropathogens in children at a single medical center in Korea between 2011 and 2014. Although ST131 isolates showed higher rates of antimicrobial resistance, clinical presentation and outcomes of patients were similar to those of patients infected with non-ST131 isolates.

To develop a new starter culture for Mozzarella cheese, the immunomodulatory action of Streptococcus macedonicus LC743 in male C57BL/6 mice was studied. Mice were fed for 7 wk with feed containing 1% Mozzarella cheese made with three kinds of starter cultures from S. macedonicus LC743 (G3), FD-DVS TCC-3 (G2) and S. macedonicus LC743 : FD-DVS TCC-3(1:1) (G4) and control (feed only, G1), respectively. No significant differences in body weight gain were observed among the various groups of mice. The spleen index and thymus index were observed and no significant differences were found among the groups. The production of TNF-${\alpha}$ of S. macedonicus LC743 group significantly increased compared to the control group. The production of IL-$1{\beta}$ was significantly enhanced by the feeding of S. macedonicus LC743 group compared to the control group. In regards to the white blood cell counts, the neutrophil percentages were significantly higher in the G1 group compared to other groups. The lymphocyte percentages were significantly higher in G2, G3 and G4 groups in comparison to the control group. The results of this study may suggest that the supplementation of S. macedonicus LC743 can increase the cytokine production activity by the activated macrophages in mice. Based on the result of this study, it could be concluded that S. macedonicus LC743 could stimulate the immune functions of mice.

The purpose of this study is to provide basic data for the medical nutrition therapy of premature infants. The general characteristics, presence of metabolic disorders, hematological profile and feeding methods were compared between the premature infant group (<37 weeks, n=61) and the full-term infant group (37$\sim$42 weeks, n=165). Birth weight (p<0.0001), birth length (p<0.005), head circumference (p<0.0001), chest circumference (p<0.0001), and Apgar scores (p<0.0001) of the neonates were all statistically lower in the premature infant group. Jaundice cases (p<0.0001) were statistically higher in the premature infant group. White blood cell counts (WBC: p<0.005), mean corpuscular volume (MCV: p<0001), mean corpuscular hemoglobin (MCH: p<0.005), mean corpuscular hemoglobin concentration (MCHC: p<0.005), and mean platelet volume (MPV: p<0.05) were statistically lower in the premature infant group. The premature infant group were fed a higher rate of premature formula than breast milk and the full-term infant group were fed a high rate of human milk at a higher rate, showing differences in kinds of feeding methods (p<0.0001) between the two groups. An infant's birth weight showed a significantly positive correlation with the infant's birth length (p<0.0001), head circumference (p<0.0001), chest circumference (p<0.0001), and Apgar scores(p<0.0001). The birth length also showed a significantly positive correlation with both head circumference (p<0.05) and chest circumference (p<0.05). Head circumference showed a significantly positive correlation with chest circumference (p<0.0001) and Apgar scores (p<0.0001). Chest circumference showed a significantly positive correlation with Apgar scores (p<0.0001). In addition, the Apgar Score at of 1 minute after birth showed a significantly positive correlation with the Apgar score at of 5 minute after birth (p<0.0001).
