The aim of this study is to explore the correlations between fasciology and yin yang doctrine. Professor Yuan developed fasciology by three-dimensional reconstruction of connective tissue (fascia) in the trunk and limbs of the human body and tracing back to tissue origins in light of biological evolution and developmental biology. Fasciology states that the human body can be divided into two systems: the supporting-storing system and the functional system. This article elaborates on the roles of the two systems and their mutual relationship. The two systems are used to analyze the yin,the yang, and their relationship. The two systems are promoted but also restricted in different contexts. The supporting-storing system is formed by undifferentiated connective tissue and provides undifferentiated cells and nutrients for differentiated cells of the functional system. Thus, the supporting-storing system could be classified as quiet, similar to yin. The functional system continuously maintains the various functional activities of the human body. Thus, the functional system could be classified as active, similar to yang. In interpreting the yin yang doctrine from the point of view of fasciology, yin can be compared with the supporting-storing system and yang can be compared with the functional system.

양유미,김성식,전은숙,박수병 대한치과교정학회 2006 대한치과교정학회지 Vol.36 No.4

본 연구는 밴드 제거 직후 및 4주 경과 후 치주조직의 임상적인 환경변화와 미생물 분포 변화를 알기 위해 시행하였다. 최후방 구치에 밴드를 포함하는 고정식 교정 장치를 장착하고 교정 치료를 1년 이상 시행한 17명의 환자를 대상으로 하였다 (평균 나이 22세, 남자 6명, 여자 11명). 최후방 구치의 밴드를 제거한 직후와 제거 후 4주가 경과한 다음에 치주조직의 탐침 깊이와 출혈 빈도를 측정하였으며, 치은 연하의 치태를 채취하여 미생물의 분포를 조사하였다. 치주질환에 관련성이 깊은 미생물 중 Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola를 직접 Polymerase Chain Reaction 방법으로 존재 여부를 확인하였다. 밴드 제거 직후와 제거 후 4주가 경과한 시점의 치주조직의 탐침 깊이와 출혈 빈도, 병원성 미생물의 존재 여부를 통계적으로 비교하였다. 탐침 깊이와 출혈 빈도는 모두 하악 좌측 구치 협면에서 감소율이 가장 크게 나타났고, 상악 우측 구치 설면에서 감소율이 가장 작게 나타났다. 병원성 미생물 중 T. denticola가 밴드 제거 4주 후에 가장 높은 감소율을 보였으며, 하악보다 상악에서 감소율이 더 크게 나타났다. 이는 비록 밴드를 장착하여 치주 환경이 불량해졌다 하더라도 올바른 구강 위생 관리가 시행된다면 밴드를 제거한 후 정상적인 치주 상태로 회복될 수 있음을 예시한 것으로 생각되었다. Objective: The purpose of this study was to evaluate clinical and microbiological changes in periodontal tissue around the banded molars after debanding. Methods: This study included 17 young adult patients treated with fixed orthodontic appliances including bands on the last molars more than 1 years. Probing depth and bleeding frequency were measured and plaque samples were collected from the last banded molars in all quadrants of each patient. All the data were collected immediately after debanding and 4 weeks after debanding. Results: Using polymerase chain reaction based on 16S rDNA, the presence of Porphyromonas gingivalis, Tannerella forsythia and Treponema denticola was detected. After debanding, probing depth, bleeding frequency, and prevalance of periodontopathogens were reduced. Probing depth and bleeding frequency were most decreased in the buccal site of the mandibular left molar and were least decreased in the lingual site of the maxillary right molar. Conclusion: The results of this study indicated that proper management of oral hygiene after debanding can recuperate unfavorable periodontal condition caused by orthodontic treatment.

관상동맥 동정맥루 기형은 매우 드문 질환으로 치료가 불필요한 경우가 대부분이나 coronary steal 현상으로 인해 증상이 발생하거나 합병증이 발생한 환자에 대해선 치료를 요한다. 최근에는 시술에 적합한 누공을 가진 선택된 환자군을 대상으로 카테터를 이용한 중재적 시술이 시행되어 수술적 치료와 유사한 결과를 얻고 있다. 저자들은 젊은 남자에서 관상동맥 동정맥루 기형과 동반된 급성 심근 경색증을 진단하여 비 수술적 방법인 카테타 코일 색전술로 성공적 치료 후 증상 및 심근 재관류에 호전을 보인 증례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. We report a case of coronary fistula between the left anterior descending and main pulmonary artery complicating acute non-Q wave myocardial infarction. A 27-year-old man visited emergency department because of severe chest pain lasting two hours. The electrocardiogram showed ST segment elevation in precordial leads V3~6. Cardiac enzymes were as follows;CK-MB:36.44 IU/L T-T:0.489 ng/mL, CPK:542 IU/L, and LDH:475 IU/L. The thallium-201 dipyridamole stress perfusion scan showed perfusion defect and reversed redistribution in the anteroseptal wall. The coronary angiogram revealed coronary artery fistula between the proximal left anterior descending artery and main pulmonary artery without significant stenoses of coronary arteries. The result of ergonovine test was negative. After micro-coil embolization to the coronary fistula, symptoms were improved. Follow-up thallium-201 scan showed normalized blood flow in the left anteroseptal wall.

This study was accomplished to develope the evaluation items for inquiry learning in the 2nd grade Middle School Science for the consecutive study of the evaluation items for inquiry learning in the 1st grade Middle School Science(U-Hang Ki et al, 1984). In this study, paper and pencil test items and performance test items are made by analyzing the abilities of inquiry according to the contents and four basic experiments from each unit in the 2nd grade Middle school science. These evaluation items were applied to tke five classes of the 2nd grade of middle school to test their validity. It is desirable that performance test schuld be used for the evaluation for the abilities of inquiry which can not be evaluated by paper and pencil test. In the evaluation methods of performance test, tester evaluation, peer evaluation and self-evaluation can be applied to the science class in a multi-student class. In higher grade, however tester evaluation is more desirable than peer and self evaluation. It is found that peer evaluation and self-evaluation make possible the perfect study by feedback.

저자들은 출산 후 발생한 심한 저혈당을 주소로 내원한 31세 여자 환자에서 뇌 자기공명영상검사에서 뇌하수체종괴가 관찰되고 복합 뇌하수체 기능검사 결과전반적인 뇌하수체 기능저하증의 소견을 보여 림프구성 뇌하수체염을 진단하고, 호르몬 보충요법만으로 경과를 관찰하여 호전된 예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Lymphocytic hypophysitis, an inflammatory disease of the pituitary gland that is often associated with pregnancy, is caused by autoimmune destruction of the pituitary gland evidenced by diffuse inflammatory cell infiltration of the pituitary gland and some kinds of detectable autoantibodies. We report a case of lymphocytic hypophysitis in a 31-year-old woman presenting with severe hypoglycemia and hyponatremia after delivery. Hormonal study revealed panhypopituitarism and magnetic resonance imaging with enhancement showed the bulging contour of the right side pituitary gland with an ill-defined mass-like lesion and nodular thickening of the stalk The patient's symptoms and biochemical data improved greatly with replacement of L-thyroxine and glucocorticoid. Partial recovery of panhypopituitarism was also seen. The follow-up tests revealed dramatic resolution of the pituitary lesion (J Kor SOC Endocrinol 1 8 : 3 25 -33 1, 2003).

Background/Aims: Chronic hepatitis B (CHB) and fatty liver (FL) often co-exist, but natural history data of this dual condition (CHB-FL) are sparse. Via a systematic review, conventional meta-analysis (MA) and individual patient-level data MA (IPDMA), we compared liver-related outcomes and mortality between CHB-FL and CHB-no FL patients. Methods: We searched 4 databases from inception to December 2021 and pooled study-level estimates using a random- effects model for conventional MA. For IPDMA, we evaluated outcomes after balancing the two study groups with inverse probability treatment weighting (IPTW) on age, sex, cirrhosis, diabetes, ALT, HBeAg, HBV DNA, and antiviral treatment. Results: We screened 2,157 articles and included 19 eligible studies (17,955 patients: 11,908 CHB-no FL; 6,047 CHB-FL) in conventional MA, which found severe heterogeneity (I2=88–95%) and no significant differences in HCC, cirrhosis, mortality, or HBsAg seroclearance incidence (P=0.27–0.93). IPDMA included 13,262 patients: 8,625 CHB-no FL and 4,637 CHB-FL patients who differed in several characteristics. The IPTW cohort included 6,955 CHB-no FL and 3,346 CHB-FL well-matched patients. CHB-FL patients (vs. CHB-no FL) had significantly lower HCC, cirrhosis, mortality and higher HBsAg seroclearance incidence (all P≤0.002), with consistent results in subgroups. CHB-FL diagnosed by liver biopsy had a higher 10-year cumulative HCC incidence than CHB-FL diagnosed with non-invasive methods (63.6% vs. 4.3%, P<0.0001). Conclusions: IPDMA data with well-matched CHB patient groups showed that FL (vs. no FL) was associated with significantly lower HCC, cirrhosis, and mortality risk and higher HBsAg seroclearance probability.

Nuclide assignment for an isolated band observed in the 10B + 114Cd reaction

Yang Qing-Yu,Song Li-Na,Ma Ying-Jun,Yang Dong,Ma Ke-Yan,Wu Xiao-Guang,Zheng Yun,Li Cong-Bo 한국물리학회 2021 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.79 No.3

Three experiments based on the nuclear reactions 14N + 110Pd, 10B + 114Cd and 11B + 114Cd were performed. Coincidences between γ-rays emitted from these reactions were measured with the same detection array which consisted of 14 HPGe detectors. A new band structure was identified using an offline analysis of coincidence data. Because of the isomeric nature of the bandhead, the new band cannot be connected to any known state in any residual nuclei of the used reactions. To assign it to a specific nucleus, we evaluated the experimental population intensities of various known bands in known residual nuclei and investigated the entrance channel effects in the three different experiments. The population intensity patterns of the known bands were observed to exhibit regular systematics. Based on such experimental systematics, we suggest that the most reasonable nuclide assignment for the new band is the 120I nucleus.

TRPM7 Is Essential for RANKL-Induced Osteoclastogenesis

Yang, Yu-Mi,Jung, Hwi-Hoon,Lee, Sung Jun,Choi, Hyung-Jun,Kim, Min Seuk,Shin, Dong Min The Korean Society of Pharmacology 2013 The Korean Journal of Physiology & Pharmacology Vol.17 No.1

The transient receptor potential melastatin type 7 (TRPM7) channel is a widely expressed non-selective cation channel with fusion to the C-terminal alpha kinase domain and regarded as a key regulator of whole body $Mg^{2+}$ homeostasis in mammals. However, the roles of TRPM7 during osteoclastogenesis in RAW264.7 cells and bone marrow-derived monocyte/macrophage precursor cells (BMMs) are not clear. In the present study, we investigate the roles of TRPM7 in osteoclastogenesis using methods of small interfering RNA (siRNA), RT-PCR, patch-clamp, and calcium imaging. RANKL (receptor activator of NF-${\kappa}B$ ligand) stimulation did not affect the TRPM7 expression and TRPM7-mediated current was activated in HEK293, RAW264.7, and BMM cells by the regulation of $Mg^{2+}$. Knock-down of TRPM7 by siTRPM7 reduced intracellular $Ca^{2+}$ concentration ($[Ca^{2+}]_i$) increases by 0 mM $[Mg^{2+}]_e$ in HEK293 cells and inhibited the generation of RANKL-induced $Ca^{2+}$ oscillations in RAW264.7 cells. Finally, knock-down of TRPM7 suppressed RANKL-mediated osteoclastogenesis such as activation and translocation of NFATc1, formation of multinucleated cells, and the bone resorptive activity, sequentially. These results suggest that TRPM7 plays an essential role in the RANKL-induced $[Ca^{2+}]_i$ oscillations that triggers the late stages of osteoclastogenesis.

Effects of platelet-rich plasma on tooth replantation in dogs: a histologic and histomorphometric analysis

Yang, Jun-Mo,Yang, Keon-Il,Lee, Kyung-Hyun,Choi, Seong-Ho,Kim, Byung-Ock,Park, Joo-Cheol,Yu, Sang-Joun Korean Academy of Periodontology 2018 Journal of Periodontal & Implant Science Vol.48 No.4

Purpose: The purpose of this study was to evaluate the effects of platelet-rich plasma (PRP) on periodontal healing of replanted root surfaces in dogs histologically and histomorphometrically. Methods: A total of 36 roots of mandibular incisors and premolars from 6 mongrel dogs were used. The roots were randomly divided into 3 groups: 1) a positive control group (n=12), in which the periodontal ligament (PDL) and cementum were retained and the roots were soaked in saline; 2) a negative control group (n=12), in which the PDL and cementum were removed and the roots were soaked in saline; and 3) an experimental group (n=12), in which the PDL and cementum were removed and the roots were soaked in PRP. After soaking the root surfaces, the extracted roots were replanted into the extraction sockets. The roots were covered using a coronally repositioned flap Results: Histologically, irregular-thickness PDL-like and cementum-like tissues were observed in the 4-week experimental group and the positive control group. PDL-like tissue and cementum-like tissue with a more uniform thickness were observed at 8 weeks. In the negative control group, PDL-like tissue and cementum-like tissue were rarely found, and root resorption and ankylosis were observed. In the cross-sectional histomorphometric analysis, the experimental group demonstrated a higher rate of formation of cementum-like tissue and a lower tooth ankylosis rate than the positive and negative control groups at 4 and 8 weeks. Although there was a significant difference in the tooth ankylosis rate and the formation of cementum-like tissue across the 3 groups (P<0.05), no statistical significance was observed between any pair of groups (P>0.017). Conclusions: Applying PRP to root surfaces during tooth replantation in dogs can reduce tooth ankylosis and increase PDL-like and cementum-like tissue formation.
