Purpose: Epstein-Barr virus (EBV) infection is related to infectious mononucleosis or nasopharyngeal cancer, and its epidemiology may change according to the socioeconomic development of communities. This study aimed to evaluate the recent epidemiology of EBV seropositive rate in Korea. Methods: We retrospectively reviewed EBV serology test results obtained from a part of clinical care at Samsung Medical Center, Seoul, South Korea, from January 2000 to December 2017. Results: The EBV seropositive rate in 26,527 subjects during the study period was 81.0% (21,485/26,527): 44.4% (2,716/6,122) in subjects aged 0-9 years, 75.8% (2,077/2,739) in those aged 10-19 years, and 94.5% (16,692/17,666) in those aged ≥20 years. The EBV seropositive rate decreased from 89.4% (8,592/9,616) in 2000-2008 to 76.2% (12,893/16,911) in 2009-2017 (P<0.001). Especially, the EBV seropositive rate in subjects aged 0-19 years significantly decreased from 2000-2008 to 2009-2017 (0-9 years, 62.8% [1,172/1,866] in 2000-2008 and 36.3% [1,544/4,256] in 2009-2017; 10-19 years, 83.8% [745/858] in 2000-2008 and 70.8% (1,332/1,881) in 2009-2017) (P<0.001). Conclusions: The EBV seropositive rate in children has decreased in the last 20 years. As the age of patients with primary EBV infection increased, there is a need for interest in clinical manifestation, such as infectious mononucleosis, in adolescents and young adults.

The ultimate objective of periodontal treatment is to get rid of an on-going periodontal disease and further regenerate the supporting tissue, which is already destroyed, functionally. Currently, the bone grafting operation using various kinds of bone grafting materials and the operation for induced regeneration of periodontal tissue using the blocking membrane are performed for regeneration of the destroyed periodontal tissue. However, there are respective limitations Galenical preparations, which are used for regeneration of periodontal of tissue, has less risk of rejective reaction or toxicity that may be incidental to degradation and their effect is sustainable. Thus, in case they are applicable to a clinic, they can he used economically. Chitosan has such compatibility, biological actions including antibacterial activity, acceleration of wound treatment, etc., and excellent mechanical characteristics, which has recently aroused more interest in it. Also, it has been reported that it promotes osteogenesis directly or indirectly by functioning as a matrix to promote migration and differentiation of a specific precussor cell (for example, osteoblast) and further inhibiting the function of such a cell as fibroblast to prevent osteogenesis. In this study, the pure chitosan solution, which was obtained by purifying chitosan, was used. However, since this chitosan is of a liquiform, it is difficult to sustain it in a defective region. It is, therefore, essential to use a carrier for delivering chitosan to, and sustaining it gradually in the defective region. In the calvarial defect model of the Sprague-Dawley rat, it is relatively easy to maintain a space. Therefore, in this study, the chitosan solution with which ACS was wetted was grafted onto the defective region, For an experimental model, a calvarial defect of rat m s selected, and a critical size of the defective region was a circular defect with a diameter of 8 mm. A group in which no treatment was conducted for the calvarial defect was set as a negative control group. Another group in which treatment was conducted with ACS only was set as a positive control group (ACS group). And another group in which treatment was conducted was conducted with by grafting the pure chitosan solution onto the defective region through ACS which was wetted with the chitosan solution was set an experimental group (Chitosan/ACS group). Chitosan was applied to the Sprague-Dawley rat's calvarial bone by applying ACS which was wetted with the chitosan solution, and each Sprague-Dawley rat was sacrificed respectively 2 weeks and 8 weeks after the operation for such application. Then, the treatment results were compared and observed histologically and his tometrically. Thereby, the following conclusions were obtained. 1. In the experimental group, a pattern was shown that from 2 weeks after the operation, vascular proliferation proceeded and osteogenesis proceeded through osteoblast infiltration, and at 8 week after the operation, ACS was almost absorbed, the amount of osteogensis was increased and many osteoid tissue layers were observed. 2. At 2 weeks after the operation, each amount of osteogenesis appeared to be 8.70.8 %, 13.62.3 % and 4.80.7 % respectively in the experimental group, the positive control group and the negative control group. Accordingly, it appeared to be higher in the Experimental group and the positive control group than in the negative control group, but there was no significant difference statistically (p<0.01). 3. At 8 weeks after the operation, each amount of osteogenesis appeared to be 62.26.1%, 17.42.5 % and 8.21.4 % respectively in the experimental group, the positive control group and the negative control group. Accordingly, it appeared to be substantially higher in the experimental group than in the positive control group and the negative control group, and there was a significant difference statistically (p<0.01). As a result of conducting the experiment, when ACS

Objectives: The purpose of this study is to identify the perceived symptoms of oral and temporomandibular joint disorders in adults and to analyze the factors affecting subjective symptoms of temporomandibular joint disorders. Methods: 249 adults over 20 years old who had subjective symptoms of temporomandibular joint disorders were surveyed and analyzed. Independent t-test and ANOVA test were used to examine the relationship between oral habits and temporomandibular joint disorder according to general characteristics. $Scheff{\acute{e}}$ test was used for post-hoc analysis. Multiple regression analysis was conducted to examine the factors affecting oral habits and temporomandibular joint disorder. Results: First, the factors affecting oral and habitual behaviors were married (p<0.05) and monthly income between 1 million~1.9 million won (p<0.001), higher temporomandibular joint disorder (p<0.01) And the degree of habit was increased. Second, the factors affecting temporomandibular joint disorder were increased in occupation (p<0.05) and the degree of oral habit (p<0.01). Conclusions: In conclusion, it was confirmed that oral habit influences temporomandibular joint disorder. Especially, it is suggested that prevention and promotion of temporomandibular joint disorder are needed to recognize the removal of oral habits.

Effects of Neuroleptics on the Opioid Receptor Binding in the Mouse Striatum

김수경,이성룡,박창교,Kim, Soo-Kyung,Lee, Seong-Ryong,Park, Chang-Gyo The Korean Society of Pharmacology 1994 대한약리학잡지 Vol.30 No.3

Our purpose was to gain insight into a possible modulatory role for ${\mu},\;{\delta},\;and\;{\kappa}$ opioid receptors by neuroleptics (chlorpromazine, thioridazine, haloperidol, sulpiride, and pimozide) in chronic morphine 5 mg/kg and 20 mg/kg treated mouse striatum. We attempted quantitative receptor assays using highly specific radioligands, $[^3H]\;DAGO\;([D-Ala^2,\;N-Mephe^4,\;Glycol^5]\;enkephalin)$, $[^3H]DPDPE\;([D-Pen^2,\;D-Pen^5]\;enkephalin)$ and $[^3H]\;DPN(diprenorphine)$ to measure the binding affinity in the experimental groups. The decrease of $[^3H]DAGO$ binding was potentiated by sulpiride and pimozide in the chronic morphine treatment (5 mg/kg and 20 mg/kg). The decrease of $[^3H]DPDPE$ binding was inhibited by chlorpromazine, thioridazine, haloperidol, sulpiride, and pimozide in chronic morphine treatment (5 mg/kg and 20 mg/kg). The decrease of $[^3H]\;DPN$ binding was significantly inhibited by chlorpromazine, thioridazine, sulpiride, and pimozide in chronic morphine 20 mg/kg treatment. $[^3H]\;DPN$ binding on the neuroleptics was antagonized by naloxone pretreatment in chronic morphine 20 mg/kg treatment. These findings suggest that neuroleptics influence opposing tonically active on the ${\delta},\;and\;{\kappa}$ opioid receptor compared with ${\mu}$ opioid receptor in the chronic morphine treated mouse striatum. 이 연구에서는 선조체에서 opioid 신경계와 dopamine 신경계의 상호 관계를 알아보기 위해서 morphine을 5m/kg, 20 mg/kg로 10일간 복강내 투여한 후 chlorpromazine, thioridazine, haloperidol, sulpiride, pimozide를 투여하였다. Opioid ${\mu},\;{\delta},\;{\kappa}$ 수용체의 binding의 변화를 관찰하고자 $[^3H]\;DAGO$, $[^3H]\;DPDPE$, 및 $[^3H]\;DPN$ binding assay를 하였으며, 그 결과 morphine (20 mg/kg) 장기 투여된 실험군에서 $[^3H]\;DAGO$, $[^3H]\;DPDPE$, 및 $[^3H]\;DPN$ 결합이 감소되었다. Morphine 20 mg/kg 장기 투여군에 chlorpromazine, thioridazine 주사시에는 morphine 5mg/kg 투여군에 비하여 $[^3H]\;DAGO$ 결합의 감소와, $[^3H]\;DPDPE$, 및 $[^3H]\;DPN$ 결합의 증가를 나타내었고, haloperidol 주사군은 $[^3H]\;DAGO$, $[^3H]\;DPN$ 결합의 감소, 및 $[^3H]\;DPDPE$ 결합의 증가를 나타내었다. Sulpiride, pimozide 주사군은 morphine 5 m/kg 투여군에 비하여 20m/kg 투여군에서 $[^3H]\;DAGO$, $[^3H]\;DPDPE$, 및 $[^3H]\;DPN$ 결합의 증가를 나타내었다. 이상의 결과로 보아 각 약물간의 opioid 결합에 대한 차이점은 있었으나, morphine 5mg/kg 투여군보다 20m/kg 투여군에서 $[^3H]\;DPDPE$ 및 $[^3H]\;DPN$의 결합이 증가의 경향을 보임으로써, 다량의 morphine을 투여했을 때 ${\mu}\;opioid$ 수용체에 비하여 ${\delta}와 ${\kappa}\;opioid$ 수용체가 더 활성화되는 것을 알 수 있었다.
