Background: The purpose of this study was to identify the distribution characteristics of radiological damage to the hand of rheumatoid arthritis patients and evaluate its effectiveness using a new damage assessment method. Methods: Hand radiographs of a total of 127 rheumatoid arthritis patients were evaluated. We simplified the pre-existing van der Heijde modified total sharp score to assess the extent of bone damage. We selected 36 joints in both hands as regions of interest in our own way, and the erosion and joint space narrowing were scored. Results: When the erosion and joint space narrowing score values of each joint of the hand were added together, the joint space narrowing score was higher than the overall erosion score. We can see that the scaphoid,lunate,radius and ulnar joints have higher erosion scores, and the 4th proximal interphalangeal (PIP), Scaphoid, Lunate, and Radius joints have higher joint space narrowing scores than other joints. These damage assessment results were similar to the results from the previous damage assessment model. Conclusions The joint space narrowing score is higher than the erosion score, suggesting that joint space narrowing precedes erosion. When checking the hand X-ray of rheumatoid arthritis patients, it is necessary to carefully check the scaphoid,lunate,radius and ulnar and 4th PIP joints, which relatively high radiographic damage scores. Also, the damage assessment model used in this study is relatively simple and does not show difference in analysis results from existing assessment models, so it can be considered for application in follow-up research.

One of the fundamental causes of periodontal disease is accumulation of bacterial plaque and calculus and most effective method of removing these plaque and calculus are scaling and root planning using hand curet and ultrasonic scaler. Many studies concerning residual degenerated mineral content after periodontal therapies have been carried out, but some problems about these studies were also known. This research studies mineral concents and distribution of residual root surfaces after perfoming hand curet and ultrasonic scaler on root surfaces of single rooted teeth which were extracted for periodontal reasons. EPMA were used to avoid errors from chemical quantative analysis and in addition SEM observation was also performed. The results were as follows. 1. No differences were found between curet group andultrasonic scaler group in Ca, P, Mg and Na level. 2. Concentration level was decreased in the sequence of Ca, P, Mg and Na. 3. Ca and P level were decreased as going to apical portion at curet group and ultrasonic scaler group. 4. More cementum was removed at cervical portion compared to other portion at curet group and ultrasonic scaler group. 5. Ca, P, Mg level was higher in dentin compared to cememtum. There was no difference in mineral level for Ca, P, Mg and Na between root surfaces treated with hand curet and ultrasonic scaler.

The purpose of this study was to evaluate the effects of ethanolic extracts of Scutellaria Radix on the alveolar bone formation in the extract socket of rat. Thirty-six Sprague-dawley rats were used in this study. Mean body weight of rat was 130+/-5g. Experimental animal were administered 0.4% beta-aminopropionitril(Sigma, USA) with the solid commercial food for 5 days. All the maxillary 1st molar of the rats were extracted by using of the tissue forcep under the general anesthesia with Pentobarbital sodium(Tokyo Chemical Co., Japan) injection into intraperitoneal space. All the extracted rats were divided into two group, experimental group which were feeded the solid food mixed ethanolic extracts of Scutellaria Radix, and control group which were feeded same food without reagent. At 1, 3, 5, 7, 9 and 14th days after tooth extraction, rats in both groups were serially sacrificed respectively. All the specimen were treated as usual method and prepared Hematoxylin-eosin stain for the light microscopic observation. The results were as follows : 1. Bone formation of extracted socket starts from the area on remained periodontal ligament than other area. 2. In the case of administration of the extracted Scutellaria Radix showed rapid healing process of connective tissue than non-administrated group. 3. In the case of administration of the extracted Scutellaria Radixshowed rapid osteogenesis than non-administrated With above results, it was concluded that ethanolic extracts of Scutellaria Radix may play a favorable role on the healing process of exatraction socket after extraction in rats. It was suggested that further study to evaluate the different concentration and administration method of ethanolic extracts of the Scutellaria Radix into same experimental model.

Objective: . Fibromyalgia (FM) is a disorder characterized by chronic diffuse pain and enhanced pain response to stimuli and is caused by central sensitization. Tinnitus also is related to central sensitization. So we investigated the impact of tinnitus on FM. Methods: . We included 22 FM patients with tinnitus and 25 FM patients without tinnitus. We assessed a range of symptoms using the Widespread Pain Index; Symptom Severity Score scale; Visual Analogue Scale of pain; and the Korean versions of the Fibromyalgia Impact Questionnaire (FIQ), the Insomnia Severity Index, and the Short-form Health Survey (SF-36). Information about the severity of tinnitus in FM patients was evaluated using the Korean version of the Tinnitus Handicap Questionnaire (THQ-K). Results: . There were significant differences between the group that had mild tinnitus (THQ＜38) and the group that had moderate-to-severe tinnitus (THQ≥38) for FIQ score (p=0.025) and for the physical functioning (p=0.003), social functioning (p=0.035), and mental health (p=0.017) components of the SF-36. Also, after dividing patients into 2 groups according to insomnia severity, significant differences were observed in FIQ score (p=0.002) and in body pain (p=0.001), general health (p=0.008), vitality (p=0.003), social functioning (p=0.003), role limitation due to emotional condition (p=0.001), and mental health (p＜0.001) components of the SF-36. Conclusion . The FM patients with severe tinnitus had more functional impairments and lower quality of life than those with mild tinnitus. Severe insomnia also was accompanied by worse health status and lower quality of life.

The purpose of this study is to evaluate the regenerated bone histollogically using titanium reinforced ePTFE(TR-ePTFE) membrane and to investigate cell occlusiveness, wound stabilization and tissue integration of TR-ePTFE membrane. Adult male rabbits (mean BW 2kg) and TR9W (W.L.Gore&Associate.INC,USA) were used in this study. Intramarrow penetration defects were surgically created with round carbide bur(HP long #6) on calvaria of rabbits. TR-ePTFE membrane was applied to defect. Then guided bone regeneration was carried out using TRePTFE membrane and resorbable suture. At 2,4,8,12 weeks after the surgery, animals were sacrificed. Nondecalcified specimens were processed for histologic analysis. The result and conclusion of this study were as follows: 1. TR-ePTFE membrane had good ability of biocompatibility and cell occlusiveness. 2. space making for guided bone regenerayion was good at TR-ePTFE membrane. 3. Tissue integration was not good at TR-ePTFE membrane. So, wound stabilization was not good. 4. At 8 weeks, 12 weeks after GBR procedure, bone formation was seen. From the above results, TR -ePTFE membrane fixed tightiy on alveolar bone might be recommended for the early bone formation.

A 34-year-old woman was admitted because of severe orthostatic headache. On CSF examination, the opening pressure was below 30 mmH2O. A spine MRI showed a large collection of extradural fluid indicating that CSF leaked into the extradural space. The headache was resolved by an epidural blood patch. We present a patient with a syndrome of CSF hypovolemia, whose spine MRI showed a large amount of leaked CSF in the epidural space of the spine.

4 beagle dogs aged over one and half years and weighed 15 to 16 Kg were utilized in this study. Experimental dehiscent defects were made in the mandibular edentulous area after removal of lower premolar. e-PTFE membrane resorbable membrane, and PDGF-BB-loaded resorbable membrane were covered at the dehiscent defects around the dental implants respectively. Animal was sacrificed at 1, 2, 3 months respectively. Non-decalicifed specimens were made and mutiple-stained for light microscopic study. The results were as follows: 1. Dehiscent defects around the implant installed in the beagle dog were an excellent defect model for studying guided bone regeneration. 2. Fibroblasts penetrated into expanded-PTFE membrane was observed and inflammatory cell infiltration was also observed around the membrane. 3. Resorbable membrane was degradaded and resorbed at 1 month after application to the dehiscent defect. Though multinucleated giant cells were observed adjacent to the membrane, that had no reverse effect on the bone regeneration. 4. PDGF-BB-loaded resorbable membrane was same capability as the resorbable membrane and e-PTFE membrane in the guided bone regeneration. 5. PDGF-BB-loaded resorbable membrane-applied site was better than resorbable membrane-applied site in the speed and maturity of bone formation. Within the above results, it was suggested that PDGF-BB-loaded resorbable membrane might have same bone regeneration capacity as nonresorbable membrane in the dehisced implant of the beagle dog and potentiality to use in human subjects.
