The Actinomyces organism is inherent in human as normal flora found in the mouth. Outside of the mouth, this organism can cause actinomycosis. Involvement of the extremity is very rare and atypical. The authors have experienced a case of actinomycosis of the foot and report with the literature review. Histopathologic finding shows multiple sulfur granules. In histochemical stains, periodic acid-Schiff, Gomori methionine silver, and gram stain were positive, and acid fast bacilli stain was negative. The patient was treated with surgical excision and antibiotic administration with Ampicillin for 6 months.

To verify the effect of subgingival calculus on the periodontal tissues in periodontitis and the effectiveness of supragingival scaling to remove the calculus, 30 teeth from healthy group (Probing pocket depth:$PPD{\leq}mm$: HP group), 15 teeth from moderate group ($4{\leq}PD<7mm$:MP group), 30 teeth from advanced group (PPD>7mm: AP group) were selected and supragingival scaling was performed before extraction of all experimental teeth. After careful extraction, the teeth were cleaned with saline and disclosed with toluidine blue and carefully examined the relationship and distance between the calculus attached on the root surface and periodontal tissues. As a result, it was; 1. The calculus was not discovered on the root surface of teeth in HP group, but was in MP and AP group, mostly on interproximal surface and furca area. The shape of the attached calculus was ovoid, trepazoid and polygonal and the calculus was distributed randomly over the root surface. 2. PPD was more than the distance between the gingival margin to the level of attached connective tissue in AP group rather than in HP and MP group. 3. The length of calculus was $2.7mm{\pm}.44mm$ in HP group and $4.1{\pm}.89in$ AP group. 4. The distance between the apical margin of calculus and the level of attached connective tissue was $2.4{\pm}.33mm$ in MP group and $3.4{\pm}.89mm$ in AP group. 5. The length of subgingival calculus was tended to increase in relation to the probing pocket depth. Therefore, it can be concluded, the calculus in periodontal pocket can not be removed completely with supragingival scaling. As the terminal part of calculus was far away with limited distance from the periodontal tissue, it can be said that the calculus was not a direct factor in destroying the periodontal tissue. In this study, the extent of the plaque was not verified but the location of calculus can be used in clinical practice for complete removal of calculus when the distance relation bewteen calculus and plaque will be known.

골내낭 처치시 치조골 재생에 관한 연구;I. e-PTFE 차단막의 효과

The ultimate objective of periodontal therapy is not only stopping the progression of periodontal disease, but also promoting the regeneration of lost periodontal tissue. Guided Tissue Regeneration, which is based on the principle that the goal of periodontal regeneration can be achieved by preventing apical migration of gingival epithelium and blocking cells originating from connective tissue, has been developed and used as a clinical procedure, and although it has shown excellent results in connective tissue healing, there have not been many studies showing its effect on the regeneration of alveolar bone loss due to periodontal disease. The objectives of this study are to investigate the result of 12 months-long treatment following guided tissue regeneration using expanded polytetrafluoroehylene membrane, and to observe the presence of regenerated alveolar bone. Forty-one teeth from 28 patients with clinical diagnosis of periodontitis has been selected. In fifteen of those interproximal intrabony defects, only flap operation had been carried out, and designated as the control group. Twenty-six intrabony defects received e-PTFE membrane following flap operation, and designated as the experimental group. Eleven teeth whose membrane had been exposed were excluded from the experiment. Various measurements including probing depth, loss of attachment, probing bone level and gingival recession have been recorded at 6th month and 12th month, and the significance of the changes has been analyzed. The results are as follows: 1. Probing depth at 6th and 12th month has shown a significant decrease in both groups (p<0.01), but significantly higher decrease was found in the experimental group compared to the control at the month(p<0.05). 2. Loss of attachment at 6th and 12th month has shown a significant decrease in both groups, but significantly higher decrease was found in the experimental group compared to the control (p<0.05). 3. Probing bone level at 6th and 12th month has shown a insignificant decrease in the control group and significant decrease in the experimental group (p<0.01). Significantly higher decrease in probing bone level was found in the experimental group (p<0.05). 4. Gingival recession at 6th and 12th month has shown a statistically significant increase (p<0.05), and the control group showed higher increase compared to the experimental group although no statistical significance was found. As these results have shown, the use of e-PTFE membrane in intrabony pockets results in marked decrease in the loss of attachment and probing bone level. This seems to indicate that e-PTFE membrane may play a role in alveolar bone regeneration in intrabony defects.

The authors have transplanted periodontally involved roots which had been root planed into healthy and periodontally involved extraction sockets, and studied the root resorption patterns as well as its effect on new bone formation and wound healing. Alveolar bone around mandibular premolars of 6 adult dogs has been surgically removed, followed by ligation of orthodontic elastic wires for 8 weeks inducing chronic periodontal disease. After removing the crown portions, roots were extracted, and notches were made on the root surfaces discriminating healthy and periodontally involved areas using burs. Controls and experimental groups were divided as follows. Control I : Transplantation of periodontally involved root into healthy extraction sockets. Control II : Transplantation of periodontally involved root into diseased extraction sockets. Experimental group I : Transplantation of root planed roots into healthy extraction sockets. Experimental group II : Transplantation of root planed roots into diseased extraction sockets. Extraction sockets were sutured after transplantations, completely submerging the roots. Healing progress was histologically observed at 2nd, 8th, 12th, and 20th weeks, and the results were as follows ; 1. No inflammation or infection within the extraction sockets had been observed in all groups throughout the experimental period. 2. Reversal lines were observed at week 2 in all groups, clearly discriminating socket walls and new bone, and numerous blood vessels were observed in the new bone trabeculae. 3. Experimental groups showed markedly less root resorption compared to the controls at week 2, but as time progressed, severe resorptions were present in all groups. 4. Localized areas of new bone ankylosis were observed, and the rest of the areas showed collagen fiber insertion with new bone formation at its periphery. 5. No clear differences were found in healing and alveolar bone regeneration between healthy and diseased extraction sockets. 6. The amount of root resorption and ankylosis had increased up to week 8 and 12, showing ankylosis of new bone and the roots. However, no further increase in ankylosis was observed at week 20. 7. Most of the cementum on healthy roots was directly ankylosed to new bone at week, 2, and were gradually resorbed and replaced by new bone thereafter. These results appear to indicate that root planing may inhibit early root resorption of transplanted roots, but gradual replacement by alveolar bone and collagen fibers eventually occur. Condition of the roots or presence of disease in extraction sockets do not appear to make marked differences in alveolar bone regeneration process.

The purpose of this study was to access the clinical effects of C31G, Listerine and CPC on the earlyx periodontitis when they were used as a adjunctives to the mechanical plaque control. Each groups were composed of 12 patients and in three test groups, C31G(Exp 1 group), Listerine(Exp 2 group) and CPC mouthrinse(Exp 3 group) were used three times a day. and as a control, placebo solution was used. Plaque index, gingival index, bleeding index, pocket depth and loss of attachment were measured as clinical parameters. After scaling and oral hygiene instruction, root planing is done two weeks later. During the eight weeks of experimental period, mouth gargling is done by all groups. The changes in the clinical parameters of the all sites were monitored every two weeks. The results were as follows : 1. The plaque index showed a siginificant difference in Exp 1 group compared with test 2 group after 2 weeks use of mouth rinse(P<0.05). 2. The gingival index showed a significant difference in Exp 1 group compared with baseline value(P<0.05) but there was no significant difference between the groups after 2 weeks use of mouthrinse (P<0.05). 3. The plaque index, gingival index and bleeding index showed a significant difference in all groups compared with baseline value after 4 weeks of root planing and mouthrinse use(P<0.05). but there was no significant difference between the groups(P<0.05). 4. Periodontal pocket depth showed a significant difference in all groups compared with baseline value after 4 weeks of root planing and mouthrinse use(P<0.05). and there was significant difference between the Exp 1 group and control group(P<0.05). 5. Loss of attachment showed a significant difference in all Exp groups compared with baseline value after 4 weeks of root planing and mouthrinse use(P<0.05). and there was significant difference between the Exp 1 group and control group(P<0.05). The results suggest that C31G, Listerine and CPC were effective for early periodontitis as a adjunctive to mechanical plaqe control.

There has been many attempts to develop a method that can regenerate periodontal tissues that were lost due to periodontal diseasd, but none of them was completely successful. This study was designed to investigate the healing and regeneration of periodontal tissue when bone substitutes such as porous replamineform hydroxyapatite and porous resorbable calcium carbonate were used in combination with oxidized cellulose membrane and collagen absorbable hemostat, compared to a control where only oxidized cellulose membrane or collagen absorbable hemostat were used. Chronic periodontitis was induced on mandibular premolars of and adult dog by placing orthodontic elastic ligatures for 10 weeks. After flap operation, the control group were received oxidized cellulose membrane (control- I )or collagen absorbable hemostat (control- II) only, while one experimental group was given either porous replamineform hydroxyapatite or porous resorbable calcium carbonate in addition to oxidized cellulose membrane (Experimental I-A, I-B), and another experimental group was treated by using either porous replamineform hydroxyapatite or porous resorbable calcium carbonate in addition to collagen absorbable hemostat. (Experimental II-A, II-B) After 56 weeks, healing was histologically analyzed with the following results. 1. Apical migration of junctional epithelium was observed only in areas coronal to the notch for both control and experimental group. 2. Inflammatory cell infiltration was not observed in any groups. 3. Oxidized cellulose membrane and collagen absorbable hemostat were completely resorbed. 4. Newly-formed cementum was observed up to the level where junctional epithelium was located, for both control and experimental groups. 5. Bone formation was limited of the middle portion of the notch in the control group, where as experimental groups showed bone formation up to the level of implant materials coronal to the notch. 6. Minute resorption of apically located portions of implanted materials was observed in experimental group I-B and II-B only.

고관절 주위 골절은 노년층이 증가함에 따라 증가하고 있고 수상 및 수술 후 발생하는 정맥혈전색전증은 생명을 위협하는 치명적인 합병증을 유발할 수 있다. 본원에서는 과거력 상 폐색전증을 진단받았으나 추시 소실 되었던 환자에서 대퇴골 전자간 골절이 발생한 후 폐색전증이 재발 하였고 항응고제를 이용하여 치료 하였다. 수상 18일 후 고관절 반치환술과 대전자 고정을 위한 갈고리금속판을 이용한 고정술을 시행하였다. 수술 다음날 정맥 혈전색전증 및 표재 대퇴동맥 패색증이 발생하였고 이 증례를 경험하여 이를 문헌고찰과 함께 보고하고자 한다. As the elderly population increases, occurrence of hip fractures has shown a rapid increase, and posttraumatic and postoperative venous thromboembolism can lead to fatal complications. Current prophylactic management includes mechanical and chemical prophylaxis. A 76-year-oldfemale, who was lost to follow-up after diagnosis of pulmonary thromboembolism four years ago, was admitted to our emergency room for a right intertrochanteric fracture. Before the operation, the thromboembolism recurred and was treated with anticoagulation medication. Bipolar hemiarthroplasty and fixation of the greater trochanter with a hook plate were performed 18 days after the trauma. Superficial femoral artery obstruction and venous thromboembolism occurred on the first day after the operation.

A 57-year-old male suffered from tingling and paraesthesia on radial side of right hand. We carried out exploration, the process being done, a radial artery passing between the two branches of bifurcated superficial radial nerve was found by accident. Then we performed dissection of the radial artrery a little more distally. It was passing above the extensors of thumb to anstomical snuff box. We treated it with ligating the radial artery, which was done a little above the bifurcated site of superficial radial nerve after angiography of upper extremity. While we were following this procedure, we noticed that symptoms had improved a lot. To our knowlege, neuropathy, by itself of superficial radial nerve by the radial artery with anatomical variation has never been reported and therefore we report this case.
