염증 (Inflammation)은 물리적인 상처나 세균감염이 되었을 때 손상된 조직을 재생하고 신체를 방어하기 위해 일어나는 선천성 면역반응으로 알려져 있다. 주로 선천면역을 담당하는 대식세포는 lipopolysaccharide, reactive oxygen species와 cytokine 등에 의해 활성화되어 tumor necrosis factor-α. interleukin-1β, interleukin-6 등 염증인자들의 생성에 관여한다. 특히, 산화질소는 superoxide 음이온과 쉽게 반응하고 peroxynitrite와 같은 독성이 강한 산화제를 생성하여 단백질 및 지질의 과산화를 유도하고 세포독성을 일으키는 것으로 보고되고 있다. 따라서 본 연구에서는 항산화 및 항염증 소재를 탐색하기 위해 오미자 (Schisandra chinensis), 꾸지뽕 (Cudrania tricuspidata)을 이용하여 항산화 활성을 평가하고자 하였으며, 세포주를 활용한 세포독성 및 항염증 활성을 확인하고자 하였다. 본 연구는 전북 순창군에서 재배된 오미자, 꾸지뽕을 열 건조(60℃) 통해 건조한 후 분말화하였다. 최적 추출 조건 선정을 위해 다양한 용매 (열수, 증류수, 주정 20, 40, 60%), 온도 (25, 40, 60, 80℃) 및 시간 (1, 2, 3, 4, 5 h) 조건에서 추출된 추출물의 총 폴리페놀 함량을 비교함으로써 최적 조건을 선정하였다. 오미자와 꾸지뽕의 DPPH 및 ABTS radical 소거 활성, 총 플라보노이드 함량을 확인하여 항산화능 및 기능성 성분 함량을 평가하였다. 또한 대식세포주인 Raw 264.7을 활용하여 MTT assay, 산화질소 생성 억제 활성을 확인하여 세포독성 및 항염증 활성을 평가하였다. 실험 결과, 오미자 및 꾸지뽕은 각각 주정 40%, 60℃ 그리고 증류수, 60℃에서 추출 시 가장 높은 총 폴리페놀 함량 (약 98.3 mg GAE/g 및 88.2 mg GAE/g)을 함유하며, DPPH 라디칼 소거 활성은 약 44.6% 및 24.4%, ABTS 라디칼 소거 활성은 약 30.3% 및 40.8%로 확인되었다. 총 플라보노이드 함량은 약 21.80 mg QE/g 및 35.68 mg QE/g으로 확인되었다. 또한 오미자 및 꾸지뽕 기능성 추출물을 100 ug/mL 처리 시 세포 독성이 나타나지 않는 것으로 확인되었으며, NO 생성량을 약 56.3% 및 21.7% 저감시켜 항염증 효능을 나타내는 것으로 확인되었다.

Due to the COVID-19 pandemic, the immuneenhancing health functional food market that protects our bodies from pathogens such as viruses continues to grow. In this study, we aimed to prove the Cheonggukjang, a high-nutrient food with high protein, fat, and dietary fiber content, as an immuneenhancing nutraceutical. Cheonggukjang water extract (CWE) increased the production of nitric oxide, reactive oxygen species, and cytokines such interleukin (IL)-6, IL-1β, and tumor necrosis factor-α without affecting viability in RAW 264.7 cells. Furthermore, CWE significantly upregulated the expression of inducible nitric oxide synthase and cyclooxygenase-2 in RAW 264.7 cells. CWE enhanced the phosphorylation of I kappa B kinase α/β and I kappa B (IκB)α, as well as the degradation of IκBα. CWE also induced increased phosphorylation of nuclear factor-kappa B p65 and facilitated the redistribution of p65 from the cytoplasm to the nucleus in RAW 264.7 cells. These findings suggest that CWE has potential as a health functional food material that can enhance the innate immune response.

The MBTI personality type test is the most widely used standardized test as an occupational aptitude test and psychological test to identify a job suitable for an individual's aptitude. However, such a self-report test has many constraints on the subject's judgment, cognitive ability, situation, and time, so there is a limit to the test. Therefore, there is a need for a test tool that can compensate for the limitations of Western psychological tests, and Myeongnology can solve the shortcomings of Western occupational tests. This is because Myeong-Ri can distinguish a natural person's disposition, aptitude, and what kind of job he or she should engage in, and it is also possible to predict what kind of job he or she will change to according to good luck. Through a comparative study of the occupational sex theory between MBTI and Myeong-ri, it can be seen that the MBTI variables and the variables of Myeong-ri are quite consistent with the occupational sex. Therefore, it was proved that Myeong-Ri is a study that can be used for professional sex counseling while supplementing the limitations of MBTI. Therefore, it is expected that this paper will contribute to the study of occupational characteristics.

The DMSA scan is a useful radiologic study in diagnosis of morphologic and functional diseases of kidney. We evaluated the distribution of sex and age, clinical manifestations, diagnosis, combined diseases, treatment and prognosis of the 61 patients with non-functioning kidney(no isotope uptake or uptake below 5% in DMSA scan) who admitted in our hospital from 1980 to 1995. The proportion of patients under 1 year old age was 46%. Sex ratio was 1.4:1 with male predominance. Most diagnosis of non-functioning kidneys were congenital such as multicystic dysplastic kidney, hydronephrosis due to ureteropelvic junction obstruction, renal agenesis and renal hypoplasia. In order of frequency thirty one percent of them were previously detected on antenatal ultrasonogram. Treatment consisted of operation in 47.5%, mostly nephrectomy and 32.8% of patients were followed up at OPD base without definite treatment. The most common combined diseases was hydronephrosis, in 4patients who had both kidneys inveloved progressed to chronic renal failure, but the prognosis in most cases were good. It is important to evaluate renal diseases in perinatal periods, and we believe that highly sensitive diagnostic study contribute to early treatment plan and thus to good prognosis.

Freeman-Sheldon Syndrome (FSS, also known as "Whistling Face Syndrome") is a rare genetic condition which characteristically includes a small "whistling" mouth, a flat mask-like face, club feet, joint contractures usually involving the fingers and hands, and under-development of the cartilage of the nose. Intelligence is usually normal. Most of the features of this syndrome are due to muscle weakness. The patient, 11 years old boy was consulted from pediatrics to pediatric dentistry due to dental management. After clinical & radiographic examinations, severe multiple problems were found. Dental problems were microsomia(whistling mouth) & micrognathia, perioral muscle contracture, restricted mouth opening, poor oral hygiene & care, generalized dental caries, high palatal vault, severe malocclusion & crowding. And Orthopedic problems, ophthalmic & respiratory, anesthetic problems were found. Then He also had psychiatric problem, hospital(dental) phobia due to previous medical history(frequent hospitalization). And he had genital problem, cryptochidism, too. Due to these intricate problems, he suffered with feeding, swallowing difficulties and showed growth retardation. For enhancing patient's oral health, pediatric dentist, orthodontist, oral surgeon, pediatrician, psychiatrist, orthopedist, they all agree with early, cautious intervention and treatment. So, he has been treated by multidisciplinary care, now he is recovering general health maintenance.

A 2-month-old intact male Pitbull terrier (weighing 1.01 kg) were referred with primary complaints of severe abdominal distension, exercise intolerance, retarded growth, yellow nasal discharge and anorexia. Diagnostic imaging studies found enlarged right atrium partitioned by abnormal membrane, severe pulmonic systolic jets (5.66 m/s of peak velocity) and right-to-left blood shunt at the inter-atrial septum. Based on clinical and diagnostic findings, the case was diagnosed as cor triatriatum dexter complicated with severe pulmonic stenosis and right-to-left shunted patent foramen ovale. Either surgical or interventional therapy has not been attempted, because of unstable patient's condition. Using blood transfusion, oxygen supply and cardiac medications (i.e., sildenafil, spironolactone, enalapril), the dog was recovered.

Patent ductus arteriosus (PDA) is a common congenital heart defect. All PDAs, regardless of size or degree of symptoms, require occlusion. Transcatheter PDA occlusion features fewer complications than trans-thoracic closure. It is also more cost-effective and has an excellent occlusion rate. Therefore, transcatheter PDA occlusion is accepted as the standard treatment option for PDA. However, tubular-type PDAs are difficult to close with ordinary detachable coils or the Amplatzer Duct Occluder; thus, these lesions remain a challenge for transcatheter closure. We attempted to occlude a tubular-type PDA by using an oversized Amplatzer Vascular Plug, which allowed intraluminal packing of the ductus. By using this treatment method, PDA occlusion was achieved safely with an excellent final outcome. We suggest that this approach may be a good option for transcatheter closure of a tubular-type PDA.

Lowe syndrome, also known as oculocerebrorenal syndrome, is a rare genetic disorder involving eyes, kidney, brain and musculoskeletal system, and occurs predominantly in males. The patient with Lowe syndrome is characterized with congenital cataracts, glaucoma, prominent forehead, thin and sparse hair, mental and growth retardation, muscular hypotonia, renal dysfunction, and metabolic bone disease. We have experienced a 10-year-old boy with Lowe syndrome who had poor oral hygiene and trouble for teeth brushing. To manage his behavior and systemic metabolic disorder, sedation was performed during dental care. Excessive calculus formation in this patient is caused by both medication and lack of ability to maintain oral hygiene. The dental management of those patients has to be focused on prevention due to difficulties in dental treatment and dangers of general anesthesia for the Lowe syndrome.

Cleft lip and palate is the most frequent congenital facial deformity of the orofacial area. Successful management of patients with cleft lip and palate requires a multidisciplinary approach from birth to adult stage. The early surgical intervention of lip and palate induces a significant incidence of maxillary growth restriction that produces secondary deformities of the jaws, and the severity of the skeletal discrepancies tends to increase with growth. The early growth modification treatment to utilize the patient's growth potential is necessary in the cleft lip and palate patients, and we must consider not only the existing skeletal discrepancies but the residual growth amount and the direction. However, once we have obtained good results with orthopedic treatment in mixed dentition stage, we must pay special attention to maintain the treatment results because of high relapse tendencies and the alterations of jaw relationships due to residual growth.

Hemophilia is a congenital hemorrhagic disease in which blood clotting is impaired and hemostatic abnormalities occur when even one of the 13 factors required for blood clotting are deficient. Among the 13 factors, hemophilia A (factor 8), hemophilia B (factor 9), and hemophilia C (factor 10), depending on the deficient coagulation factor. A male patient in his 40s diagnosed with hemophilia A visited the dentist at Eulji University Hospital for problems with alveolar bone absorption and periodontal abscess caused by overall chronic tooth inflammation, and showed overall bone absorption and inflammation at the time of initial diagnosis. No complications or bleeding tendency were observed in the rest of the area except for #35 and #36 due to regular visits for 10 years, overall good oral conditions, and no side effects or complications were observed.
