Non-small cell lung cancer (NSCLC) is the leading cause of cancer related deaths. Most patients were presented with advanced disease at the time of diagnosis. In advanced NSCLC, it is almost impossible to anticipate complete remission by using only cytotoxic chemotherapy or molecularly targeted agents. In our case, two patients were diagnosed as advanced NSCLC and received chemotherapy. They achieved complete response (CR). After finishing treatment, disease recurred. They were retreated with the same regimens and achieved second CR. Until now, they have received each regimen, continuously, and the CR state has been maintained.

포스트가 축조된 치아를 재근관 치료하는 경우 성공적인 비외과적 재근관치료를 시행하기 위해서는 포스트 제거가 선행되어야 한다. 기존의 포스트를 제거하는 방법으로는 초음파기구, Ruddle post removal system, Eaggler post remover, Masserann kit을 이용하는 방법 등 여러 가지가 소개 되고 있으나 기존의 방법들은 각 기구에 맞게 코어를 삭제해야 하는 시간과 많은 노력이 요구되며 포스트 제거시 치아나 포스트의 파절이 유발되기도 한다 그러나 최근에는 기존의 방법과는 다른 ATD automatic bridge remover를 이용해 포스트를 제거하는 새로운 방법이 소개되고 있으며 코어에 구멍을 형성하는 시간만 소요되어 비교적 빨리 제거 할 수 있다는 장점을 가지고 있다. 따라서 본 증례에서는 ATD automatic bridge remover를 이용해 주조포스트를 제거하고 성공적으로 재근관치료를 시행한 증례에 대해서 보고하고자 한다.

완전 무치악 환자의 가철성 보철 수복 치료에서 잔존 치조제의 흡수가 심한 경우 임플란트를 이용하면 부가적인 지지, 유지 및 안정을 제공할 수 있다. 환자의 상태에 대한 정확한 진단 및 평가 없이 보철물을 제작하게 되면 생역학적, 기능적, 심미적으로 불리한 치료 결과를 야기하게 된다. 본 증례의 환자는 개인치과의원에서 상·하악 임플란트 피개의치를 제작하였으나 연조직 통증 및 기존 의치 유지력 저하로 재치료를 위해 내원하였다. 진단 결과 기존 의치의 수직고경이 다소 낮게 설정되어 있어 이를 거상하고, milled bar와 부가적인 attachment를 이용한 임플란트 피개의치를 제작하였다. 이를 통해 증진된 구강위생과 기능적, 심미적인 면에서 만족할 만한 결과를 얻었기에 보고하는 바이다.

Objectives: The purpose of this study was to confirm the relavance between the dependent variables and the treatment effects of nonsurgical spinal decompression(NSD). Methods: 105 patients suffering from disc herniation and treated with NSD were investigated and analyzed. Results: The intention of retreatment showed a tendency to be higher in having occupation, western treatment only before NSD(WTB) and non-western treatment(WTN) group. As the number of NSD increased, satisfaction score and the Numeric Rating Scale(NRS) difference increased and the NRS after NSD decreased. On the other hand, as western treatment after NSD increased, satisfaction score and the NRS difference decreased and the NRS after NSD increased. The odds ratio of having intention of retreatment was lower in western treatment only after NSD(WTA) group than WTN group. The NRS difference showed a high tendency in the age group of 20s, 60s, and 70s and older. The NRS difference of group with NSD more than 10 times was higher than that of the group with less than 10 times. Satisfaction score of WTN and WTB group was higher than that of WTA group. Adjusted NRS after NSD was the lowest in non-western treatment group and the highest in WTA group. Adjusted NRS after NSD was the lowest in the group with NSD over 21 times, and the NRS after NSD increased as the number of NSD decreased. Conclusion: This study included patients with cervical or lumbar disc herniation and showed that occupation, the number of NSD, western treatment and age statistically affected the treatment effect.

Objectives: To evaluate the fracture incidence of Reciproc R25 instruments (VDW) used during non-surgical root canal retreatments performed by students in a postgraduate endodontic program. Materials and Methods: From the analysis of clinical record cards and periapical radiographs of root canal retreatments performed by postgraduate students using the Reciproc R25, a total of 1,016 teeth (2,544 root canals) were selected. The instruments were discarded after a single use. The general incidence of instrument fractures and its frequency was analyzed considering the group of teeth and the root thirds where the fractures occurred. Statistical analysis was performed using the χ² test (p < 0.01). Results: Seven instruments were separated during the procedures. The percentage of fracture in relation to the number of instrumented canals was 0.27% and 0.68% in relation to the number of instrumented teeth. Four fractures occurred in maxillary molars, 1 in a mandibular molar, 1 in a mandibular premolar and 1 in a maxillary incisor. A greater number of fractures was observed in molars when compared with the number of fractures observed in the other dental groups (p < 0.01). Considering all of the instrument fractures, 71.43% were located in the apical third and 28.57% in the middle third (p < 0.01). One instrument fragment was removed, one bypassed, while in 5 cases, the instrument fragment remained inside the root canal. Conclusions: The use of Reciproc R25 instruments in root canal retreatments carried out by postgraduate students was associated with a low incidence of fractures.

To investigate the re-treatment time of Microcotyle sebastis by oral administration of praziquantel, the residue levels of praziquantel in plasma of rockfish Sebastes schlegeli administered orally at a dose of 200 mg/kg B.W. were analyzed by reversed-phase HPLC, and the concentrations of praziquantel in the plasma were correlated with the extermination of M. sebastis. The absorption and depletion of praziquantel in the blood of rockfish were fast and the residual concentrations of praziquantel declined below $4\mu g/mL$ within 24 hr post treatment. Most of worms were exterminated within 3 hr after oral administration of praziquantel, however, a small number of M. sebastis were not killed by the treatment until end of the experiment. Considering fast drop of praziquantel in blood and extermination pattern of M. sebastis in the present results, retreatment at an interval of 9-12 hr would be effective for eradication of M. sebastis.

In the field of acupuncture and moxibustion, the theory of taboo of acupuncture and moxibustion on the basis of where the 'Qi and the soul of the men(人氣 人神)' exist became the foundation of the 'theory of chrono-acupunclure and moxibustion(時間性鍼灸法), that takes into account the thrift and retreatment of the Qi(氣) and the 'soul of the men' according to day and time. The fields of acupuncture and moxibustion in the theory of 'Yun Qi(運氣) which takes into account time space are the theories of the 'ZiWuLinZhu(子午流注)' and the 'LingGuiBaFa(靈龜八法)'. While the theory of the 'ZiWuLlnZhu' has the nature of time, 'LingGuiBaFa' has the nature of space comparatively. So the theory of 'Yun Qi' adopted and improved the time-space background that is the basis of the theory of the 'ZiWuLinZhu' and the 'LingGuiBaFa'.
