Objectives : Phyllostachys Folium is leaves of Phyllostachys nigra var. henesis $S_{TAPF}$. In the East Asian traditional medicine, the herb has been used to treat nasal bleeding, dysuria, epilepsy and etc. The present study was conducted to evaluate the anti-inflammatory effects of the Phyllostachys Folium water extracts (PFE) in vitro and in vivo model. Methods : Cell viability was measured by MTT assay after the treatment of PFE and NO production was monitored by measuring the nitrite content in culture medium. iNOS, COX-2, $I{\kappa}B$, $p-I{\kappa}B{\alpha}$ amd $NF{\kappa}B$ were detected by immunoblot analysis, and levels of cytokine were analyzed by sandwich ELISA kit. Anti-edema effect of PFE was determined in the carrageenan-induced paw edema model in rats. Results : LPS increased NO and cytokines levels compared with control, these increases were attenuated by PFE. In addition, LPS-induced pro-inflammatory proteins such as iNOS, COX-2 were down regulated by PFE. These anti-inflammatory effect of PFE results from inhibition of phosphorylation of $I{\kappa}B$ and translocation of $NF-{\kappa}B$. Conclusion : These results show that PFE has some anti-inflammatory effects which might play a role in gram-negative bacterial infection inflammation and $NF{\kappa}B$ activated diseases.

BACKGROUND/OBJECTIVES: Epithelial-mesenchymal transition (EMT) is involved in not only cancer development and metastasis but also non-cancerous conditions. Hypoxia is one of the proposed critical factors contributing to formation of chronic rhinosinusitis or nasal polyposis. Wheatgrass (Triticum aestivum) has antioxidant, anti-aging, and anti-inflammatory effects. In this study, we analyzed whether wheatgrass has an inhibitory effect on the EMT process in airway epithelial cells. MATERIALS/METHODS: A549 human lung adenocarcinoma cells were incubated in hypoxic conditions ($CO_2$ 5%/$O_2$ 1%) for 24 h in the presence of different concentrations of wheatgrass extract (50, 75, 100, and $150{\mu}g/mL$) and changes in expression of epithelial or mesenchymal markers were evaluated by immunoblotting and immunofluorescence. Accordingly, associated EMT-related transcriptional factors, Snail and Smad, were also evaluated. RESULTS: Hypoxia increased expression of N-cadherin and reduced expression of E-cadherin. Mechanistically, E-cadherin levels were recovered during hypoxia by silencing hypoxia inducible factor (HIF)-$1{\alpha}$ or administering wheatgrass extract. Wheatgrass inhibited the hypoxia-mediated EMT by reducing the expression of phosphorylated Smad3 (pSmad3) and Snail. It suppressed the hypoxia-mediated EMT processes of airway epithelial cells via HIF-$1{\alpha}$ and the pSmad3 signaling pathway. CONCLUSION: These results suggest that wheatgrass has potential as a therapeutic or supplementary agent for HIF-1-related diseases.

Background: Klebsiella spp. is an important conditional pathogen in humans and animals. However, due to the indiscriminate use of antibiotics, the incidence of antimicrobial resistance has increased. Objectives: The purpose of this study was to investigate antimicrobial resistance in strains of Klebsiella strains and the phylogenetic relatedness of extended-spectrum cephalosporin (ESC)-resistance among Klebsiella strains isolated from clinically ill companion animals. Methods: A total of 336 clinical specimens were collected from animal hospitals. Identification of Klebsiella species, determination of minimum inhibitory concentrations, detection of ESC resistance genes, polymerase chain reaction-based replicon typing of plasmids by conjugation, and multilocus sequence typing were performed. Results: Forty-three Klebsiella strains were isolated and, subsequently, 28 were identified as K. pneumoniae, 11 as K. oxytoca, and 4 as K. aerogenes. Eleven strains were isolated from feces, followed by 10 from ear, 7 from the nasal cavity, 6 from urine, 5 from genitals, and 4 from skin. Klebsiella isolates showed more than 40% resistance to penicillin, cephalosporin, fluoroquinolone, and aminoglycoside. ESCresistance genes, CTX-M groups (CTX-M-3, CTX-M-15, and CTX-M-65), and AmpC (CMY-2 and DHA-1) were most common in the K. pneumoniae strains. Some K. pneumoniae carrying CTX-M or AmpC were transferred via IncFII plasmids. Two sequence types, ST709 and ST307, from K. pneumoniae were most common. Conclusions: In conclusion, this is the first report on the prevalence, ESCresistance genotypes, and sequence types of Klebsiella strains isolated from clinically ill companion animals. The combination of infectious diseases and antimicrobial resistance by Klebsiella in companion animals suggest that, in clinical veterinary, antibiotic selection should be made carefully and in conjunction with the disease diagnosis.

Rhinitis is among the most common respiratory diseases in children. Nonallergic rhinitis, which involves nasal symptoms without evidence of systemic allergic inflammation or infection, is a heterogeneous entity with diverse manifestations and intensities. Nonallergic rhinitis accounts for 16%-89% of the chronic rhinitis cases, affecting 1%-50% (median 10%) of the total pediatric population. The clinical course of nonallergic rhinitis is generally rather mild and less likely to be associated with allergic comorbidities than allergic rhinitis. Here, we aimed to estimate the rate of coexisting comorbidities of nonallergic rhinitis. Nonallergic rhinitis is more prevalent during the first 2 years of life; however, its underestimation for children with atopic tendencies is likely due to low positive rates of specific allergic tests during early childhood. Local allergic rhinitis is a recently noted phenotype with rates similar to those in adults (median, 44%; range, 4%-67%), among patients previously diagnosed with nonallergic rhinitis. Idiopathic rhinitis, a subtype of nonallergic rhinitis, has been poorly studied in children, and its rates are known to be lower than those in adults. The prevalence of nonallergic rhinitis with eosinophilia syndrome is even lower. A correlation between nonallergic rhinitis and pollution has been suggested owing to the recent increase in nonallergic rhinitis rates in highly developing regions such as some Asian countries, but many aspects remain unknown. Conventional treatments include antihistamines, intranasal corticosteroids, and recent treatments include combination of intranasal corticosteroids with azelastin or decongestants. Here we review the prevalence, diagnosis, comorbidities, and treatment recommendations for nonallergic rhinitis versus allergic rhinitis in children.

Renal cortical necrosis (RCN) is patchy or diffuse ischemic destruction of the renal cortex caused by significantly reduced renal arterial perfusion. It is a rare cause of acute kidney injury (AKI) and is associated with high mortality. Here, we review the case of RCN in a 15-year-old boy who developed AKI. A 15-year-old boy was referred to our hospital from a local hospital due to a sharp decrease in his renal function. He presented with acute flank pain, nausea with vomiting, and oliguria for the past two days. He had taken a single dose of antihistamine for nasal congestion. At our hospital, his peak blood pressure was 148/83 mmHg and he had a high body mass index of $32.9kg/m^2$. The laboratory data showed a blood urea nitrogen (BUN) of 28.4 mg/dL, a creatinine of 4.26 mg/dL, and a glomerular filtration rate estimated from the serum cystatin C of $20.2mL/min/1.73m^2$. Proteinuria (spot urine protein to creatinine ratio 1.66) with pyuria was observed. Kidney sonography showed parenchymal swelling and increased renal echogenicity. Due to rapidly progressing nephritis, steroid pulse therapy (750 mg/IV) was done on the second day of his admission and the patient showed complete recovery with normal renal function. However, the kidney biopsy findings revealed renal cortical hemorrhagic necrosis. Multifocal, relatively well-circumscribed, hemorrhagic necrotic areas (about 25%) were detected in the tubulointerstitium. Although RCN is an unusual cause of AKI, especially in children, pediatricians should consider the possibility of RCN when evaluating patients with rapidly decreasing renal function.

Objectives This study aims to identify differences in clinical manifestations of COVID-19 between different Sasang constitution. Methods Subjects were recruited from August 29, 2022, to July 11, 2023. COVID-19 clinical symptoms were self-reported via questionnaires. Sasang constitutional diagnosis was performed using the K-PRISM, and Sasang constitutional specialist. Results A total of 66 subjects were recruited for the study, and the Sasang constitutional distribution of the subjects was 19 soyangin, 25 taeeumin, and 22 soeumin. For most of the COVID-19 clinical manifestations, the study found that soyangin experienced symptoms at a higher rate than other constitutions. Among the symptoms observed in the study, sore throat, pantalgia, and cough were severe in all subjects regardless of constitution. Soeumin was more likely to experience abdominal pain, chest pain, and diarrhea, while soyangin was more likely to experience chest pain, nausea/vomiting, diarrhea, and cutaneous symptoms compared to other constitutions. Taeeumin had more sputm, nasal congestion, and skin symptoms, but fewer digestive symptoms. There were differences in the onset and duration of symptoms by constitution. Conclusions This study is an important contribution to our understanding of the differences in response to the COVID-19 virus among different Sasang constitutions. Symptomatic differences between constitutions may have important implications for prevention and treatment strategies for infectious diseases, and personalized treatment and management based on these differences may be needed in the future.

연구 배경 : 황색 포도상구균은 피부, 연조직 감염, 골 관절염, 폐렴, 균혈증, 식중독 등을 일으키는 병원균으로 이로 인한 치료를 하지 못했을 때 높은 이환율과 치환율을 보여주고 있다. 내과계 중환자실로 입원한 환자와 일반 병실로 입원한 환자간의 MRSA에 대한 보균율과 선별검사의 의의를 알아보기 위하여 본 연구를 진행하였다. 방 법 : 2004년 6월부터 9월까지 내과계 중환자실과 일반병실로 입원한 환자를 대상으로 하였다. 내원 24 시간 이내에 비공과 인후에서 배양 검사를 실시하여 양군을 서로 비교하였다. 결 과 : 대상환자는 중환자실 121명과 일반병실 84명이었다. 비공에서의 MRSA 보균율은 중환자실군에서 3명(2.5%), 일반 병실군에서 3명(3.6%)으로 양군에서 차이점은 보이지 않았다. 인후에서의 MRSA 보균율에서는 중환자실군과 일반 병실군에서 각각 2명(1.7%), 0명으로 유의한 차이는 없었다. 입원 경로, 수술 경험, 이전 입원 경험에 대한 조사에서도 MRSA 양성군과 음성인 군에서 차이는 없었다. 결 론 : 내과계 중환자실 입원환자에서 MRSA 보균율은 3.3%였다. 내과계 중환자실로 입원한 환자와 일반 병실 환자에서 MRSA의 보균율에 있어 큰 차이가 없어 MRSA에 대한 선별 검사는 꼭 필요하리라 생각되지 않는다. 앞으로 MRSA 보균의 위험 인자가 있는 환자들을 대상으로 한 MRSA 선별검사에 대한 연구가 필요하다.
