Purpose: To evaluate the diagnostic value of the Vesikari Scoring System (VSS) as an early predictor of pathogens in children with acute gastroenteritis (AG). Methods: In this retrospective study, the VSS score, absolute neutrophil count (ANC), and C-reactive protein (CRP) levels were analyzed in 107 hospitalized children with AG, aged 6 months to 17 years. Patients were divided into nonspecific, viral, and bacterial groups according to the pathogens detected using a multiplex polymerase chain reaction (PCR) test. Results: Patients in the bacterial group had significantly higher CRP values and VSS scores compared to those in the viral group and significantly higher VSS scores compared to those in the nonspecific group (P<0.05). Patients in the viral group had significantly higher VSS scores than those in the nonspecific group (P<0.05). Logistic regression analysis revealed that VSS was the most effective diagnostic tool for predicting the type of pathogen (P<0.05). The area under the receiver operating characteristics curve of VSS was significantly greater than that for ANC and CRP (P<0.05). At a cutoff point of 10 in the VSS, an acceptable diagnostic accuracy could be achieved for distinguishing between bacterial and viral pathogens in AG. Conclusion: VSS can be considered a useful and reliable infectious marker for pediatric gastroenteritis. VSS may be a good early predictor of the type of pathogen, enabling development of a treatment plan before results from a stool culture or PCR test are available.

Purpose: We sought to examine the relationship between the clinical manifestations of nonspecific reactive hepatitis and respiratory virus infection in pediatric patients. Methods: Patients admitted to the pediatric unit of Konyang University Hospital for lower respiratory tract disease between January 1, 2014 and December 31, 2014 and who underwent reverse transcriptase polymerase chain reaction tests were examined. The patients were divided into those with increased levels of alanine aminotransferase (ALT) or aspartate aminotransferase (AST) and those with normal ALT or AST levels. Further, patients with increased ALT and AST levels were individually compared with patients in the normal group, and the blood test results were compared according to the type of respiratory virus. Results: Patients with increased ALT or AST levels had one more day of hospital stay, on average, compared with patients in the normal group ($5.3{\pm}3.1$ days vs. $4.4{\pm}3.0$ days, p=0.019). Patients in the increased ALT level group were younger and had a longer mean hospital stay, compared with patients in the normal group (p=0.022 and 0.003, respectively). The incidences of increased ALT or AST were the highest in adenovirus infections (6/24, 25.0%), followed by enterovirus (2/11, 18.2%) and respiratory syncytial virus A (21/131, 16.0%) infections. Conclusion: Nonspecific reactive hepatitis is more common among patients with adenovirus, enterovirus and respiratory syncytial virus infection, as well as among those infected at a younger age. Compared with AST levels, ALT levels are better indicators of the severity of nonspecific reactive hepatitis.

Patient with complaints of swelling, pain in the maxillaly region and discomfort visited Seoul National University Dental Hospital in August last year. Clinical examination and diagnostic imagings implied he was suffered from fungal hyphal infection but no causative fungus was found by the histopathologic and microbiologic investigation. Therefore he was diagnosed with nonspecific inflammation. But as yet, we do think this case is very similar to some kinds of mucormycosis. So we presented this case for more thorough discussion.Followings are founded in the examination. 1. Patient had suffered from Diabetes mellitus and complained of stuffness, headache, swelling in buccal cheeks and paresthesia And we found more maxillary bony destruction and ulcer with elevated margin in the palate by clinical examination. 2. In the first visit, Plain films revealed general bony destruction of the maxilla, radiopaqueness in the sinonasal cavities. or and MRI showed soft tissue mass filled in the paranasal sinus except frontal sinus and bony destruction in involved bones. 3. No causative bacteria and fungus was found in the biopsy and microbiologic cultures. 4. Caldwell-Luc operation and curettage were carried and antJbiotics were taken for 4 months. But now he was worse than in the past 5. In the second visit, involvement of orbit, parapharyngeal sinus, clivus, cavernous sinus and middle cranial fossa were seen clearly in the or and MRI.

The formation of zinc finger peptide-$Zn^{2+}$ complexes in electrospray ionization mass spectrometry (ESI-MS) was examined using three different metal ion sources: $ZnCl_2$, $Zn(CH_3COO)_2$, and $Zn(OOC(CHOH)_2COO)$. For the four zinc finger peptides (Sp1-1, Sp1-3, CF2II-4, and CF2II-6) that bind only a single $Zn^{2+}$ in the native condition, electrospray of apo-zinc finger in solution containing $ZnCl_2$ or $Zn(CH_3COO)_2$ resulted in the formation of zinc finger-$Zn^{2+}$ complexes with multiple zinc ions. This result suggests the formation of nonspecific zinc finger-$Zn^{2+}$ complexes. Zn(tartrate), $Zn(OOC(CHOH)_2COO)$, mainly produced specific zinc finger-$Zn^{2+}$ complexes with a single zinc ion. This study clearly indicates that tartrate is an excellent counter ion in ESI-MS studies of zinc finger-$Zn^{2+}$ complexes, which prevents the formation of nonspecific zinc finger-$Zn^{2+}$ complexes.

Effects of synthetic oligodeoxynucleotides (ODNs) containing cytidine-phosphate-guanosine(CpG) motif(s) on nonspecific immune responses of olive flounder (Paralichthys olivaceus) and on protection against lethal infection with Edwardsiella tarda were investigated. Respiratory bunt activities of the head kidney phagocytes in the fish injected either 0.25 or 0.5 ${\mu}g/fish$of ODNs containing CpG motifs (ODN 1826 and ODN 1670) were significantly higher than those injected with an ODN containing a guanosine-phosphate-cytidine (GpC) motif (ODN 1720) or with hanks balanced salt solution (HBSS, control) at 3, 5 and 7 days after injection. The serum lysozyme activities of fish injected with 0.25${\mu}g$ of ODN 1826 were significantly higher than those injected with ODN 1720 or HBSS at 1 and 7 days after injection. At 7 days after injection, the group of fish injected with CpG ODNs showed higher serum lysozyme activities than fish injected with ODN 1720 or control. The group of fish injected 0.25 or 0.5${\mu}g$ of CpG ODNs showed higher survival rates than those treated with GpC ODN and the control group after challenge with Edwardsiella tarda. The present study proved the ability of synthetic CpG ODN to increase nonspecific immune responses and disease resistance in olive flounder.

The aim of this study was to investigate in vivo toxicity and effects of two phthalate esters (PEs), di-n-butylphthalate (DBP) and di-2-ethylhexyl phthalate (DEHP), on the immune system of the bagrid catfish, Pseudobagrus fulvidraco. Groups of experimental fish were subjected to daily intraperitoneal injections of 300 or 1000 mg $kg^{-1}$ of DBP or DEHP for 3 days, and the cellularity and functional activity of phagocytes were measured in the spleen and pronephros (head kidney). The number of spleen leukocyte cells increased significantly (p<0.05) in response to low and high doses of DEHP and DBP, respectively; however, the cellularity of the pronephros was more susceptible to higher dose of DEHP than DBP. Nonspecific immunity, as determined by the phagocytic index (PI) and phagocytic capacity (PC), was significantly depressed by DEHP at 1000 $1000mg\;kg^{-1}\;day^{-1}$ in the pronephros at 3 days after injection. Furthermore, significantly (p<0.05) increased levels of serum glutamic oxaloacetate transaminase (GOT) and glutamic pyruvate transaminase (GPT) indicated marked hepatic dysfunction in immunosuppressed fish. Treated fish showed a significant reduction in total serum protein but no significant alteration in lysozyme activity. These results demonstrate the sensitivity of the fish immune response for predicting PE-induced immunotoxicity.

The purpose of the present study was to investigate the immune-enhancing activity of selenizing Codonopsis pilosula polysaccharide (sCPPS₅) in nonspecific immune response. In in vitro experiment, the results showed that sCPPS₅ could promote the phagocytic uptake, NO production, and TNF-α and IL-6 secretion of RAW264.7 cells. sCPPS₅ could also strongly increase the IκB-α degradation in the cytosol and the translocation of NF-κB p65 subunit into the nucleus of RAW264.7 cells. In the vivo experiment, sCPPS₅ at medium doses could significantly improve the phagocytic index of peritoneal macrophages and induce the secretion of TNF-α and IL-6. Moreover, the effect of sCPPS₅ was significantly better than Codonopsis pilosula polysaccharide (CPPS). These results indicated that selenylation modification could significantly enhance the immune-enhancing activity of CPPS in the nonspecific immune response.
