  • Purpose : The aim of this study was to investigate the effect of the autologous blood injection (ABI) for chronic recurrent temporomandibular joint (TMJ) dislocation using magnetic resonance imaging (MRI). Materials and Methods : ABI was applied to 14 patients who had chronic recurrent TMJ dislocation. MRIs of the patients were taken and compared before and one month after the injection. Results : All of the patients had no dislocations of their TMJs on clinical examination one month after the injection. In the pre-injection, unilateral or bilateral TMJ dislocations were observed on MRIs in all patients. One month after the injection, TMJ dislocations were not observed in MRI evaluation of any patients. A significant structural change that caused by ABI was not observed. Conclusion : The procedure was easy to perform and it caused no foreign body reaction. However, it was unclear how the procedure prevented the dislocation.

  • Autologous fat grafts are widely used in soft-tissue augmentation and reconstruction. To reduce the unpredictability of fat grafts and to improve their long-term survival, cell-assisted lipotransfer (CAL) was introduced. In this alternative method, autologous fat is mixed and grafted with stromal vascular fraction cells or adipose-derived stem/stromal cells (ASCs). In regenerative medicine, ASCs exhibit excellent therapeutic potential and are also simple to harvest. Although the efficacy of CAL has been demonstrated in experimental and clinical research, studies on its safety in terms of oncologic risk have reported inconclusive results. In order to establish CAL as a viable stem cell therapeutic approach, it will be necessary to demonstrate its oncologic safety in basic and clinical studies. Doing so could transform the paradigm of clinical strategy and practice for the treatment of a wide variety of diseases.

  • Background: Onlay vein patch coronary angioplasty has been known to be an option for coronary artery stenosis in the selective iesions Material and method: During the period between July 1997 and August 1999, coronary angioplasty using autologous saphenous vein was done on 16 sites in 14 cases for the stenotic lesion at the bifurcation area and significantly stenosis distal to anastomosis. Result: Early patency of the angioplasty site was 85.7% at postoperative day 7. There was no statistically difference in graft patency, operative parameters, and complications compared to conventional anatomosis(p>0.05). Conclusion: Despite the small number of cases, the patency rate of the coronary patch angioplasty was comparable to the conventional CABG. Coronary artery only patch angioplasty could be performed in highly selected coronary arteries.

  • Cystic adventitial disease is rare, but it is one of the well-recognized causes of non-atherosclerotic arterial stenosis or obstruction. Despite one of its most common symptoms being chronic intermittent claudication, it may be misdiagnosed as arterial embolism when presented with acute ischemic symptoms. Surgical resection is recommended because of recurrence or a low success rate with aspiration or endovascular stent. We performed resection and repair with autologous vein patch for cystic adventitial disease of the popliteal artery of a 57-year-old man presenting with pain, pallor, and paresthesia, without any postoperative complications or recurrence.

  • Membranes obtained from the normal human RBC population were separated by continuous sucrose density gradient centrifugation and the density-fractionated membranes were then examined for changes in molecular markers. This study focuses on changes of (i) the membrane protein profile, (ii) differences in membrane-associsted enzyme activities, and (iii) the amount of autologous IgG bound. The following observations were made: (i) ratios for band 4. la over the sum of bands (4. la + 4.Ib) ranged from 0.58 to 0.79 for membranes of lowest density; (ii) significant changes in bound glyceraldehyde-3-phosphate dehydrogenase and acetvlcholinesterase activities were found; (iii) the amounts of autolosous IgG's attached to the red blood cells was highest in the membrane fraction of lowest density.

  • This is a genuine case report of the Ross operation without the use of homografts or heterografts in reconstruction of the right ventricular outflow tract. A 8-year-old boy with congenital aortic stenosis underwent aortic valve replacement with a pulmonary autograft and right ventricular outflow tract reconstruction with a pericardial conduit bearing autologous aortic monocusp. The postoperative echocardiography and cardiac angiography revealed good ventricular function and competent neoaortic valve. He has been followed up for 19 months.

  • Laryngotracheal stenosis is one of the most troublesome diseases in the Em field. Subglottic stenosis can be treated by a cricoid augmentation with rib cartilage. In case of tracheal stenosis, the treatment of choice is by tracheal end-to-end anastomosis after resection of the stenotic site. However, in case of subglottic stenosis combined with tracheal stenosis, it is hard to manage. Even though several methods(such as thyrotracheal anastomosis) have been tried, they have some limitations too much excision of normal trachea and too much pulling up of the trachea after resection of the stenotic lesion. The authors have managed two cases of laryngotracheal stenosis as an anterior and posterior subglottic augmentation with an autologous cartilage graft and laryngotracheal anastomosis. The first few weeks after the operation, we could do a decannulation successfully, but in one case the patient developed restenosis. Even though one case was unsuccessful, the authors believe that this method could be used in the treatment of laryngotracheal stenosis.

  • Although modern medicine has made great strides in the management of burn injuries, associated complications such as pain, infection, dyspigmentation, and scarring have yet to be fully dealt with. Although skin grafting and meshing are routinely performed on burn patients, this method poses a risk for adverse effects. Activated autologous platelet-rich plasma (aaPRP), which is increasingly used in the field of plastic surgery, contains growth factors beneficial for wound regeneration. Seven cases of burns with varying severity and conditions that were treated with intralesional subcutaneous injection and intravenous aaPRP are presented and discussed herein. This case series indicates that subcutaneous and intravenous aaPRP is a safe procedure with the potential to be an alternative when skin grafting cannot be done or as an adjunct treatment to skin grafting.

  • The number of patients with coronary artery disease and peripheral vascular disease are increasing, and the need of small diameter vessel is also increasing. We developed small diameter artificial vessel and experimented in vivo. We got allogenic valve from mongrel dogs, and removed all cells from the allogenic valve. Then, we seeded autologous bone marrow cells onto the decellularized scaffold. After implantation of artificial vessel into the canine carotid artery, we performed angiography regularly. In case of vessel occlusion or at 8 weeks after operation, we euthanized dogs, and retrieved the implanted artificial vessels. Control vessels were all occluded except one (which developed aneurysmal dilatation). But autologous cell seeded vascular graft were patent by 4 weeks in one, by 6 in one and by 8 weeks in two. Histologic examination of patent vessel revealed similar structure to native artery. Tissue-engineered vascular graft manufactured with decellularized allogenic matrix and autologous bone marrow cells showed that tissue engineered graft had similar structure to native artery.

  • Objective : To report eruption of maxillary canine through Bio-$Oss^{(R)}$ graft in patients with secondary bone-grafted alveolar clefts. Methods : Secondary alveolar bone grafts placed in the cleft alveolar defect have been shown to support dental eruption through the graft and may further affect the prevalence of impacted teeth. As the case may be, it could be difficult to do secondary alveolar bone graft with autologous bone. In particular, few reports have been shown the secondary bone graft with heterogenous bone(Bio-$Oss^{(R)}$). In this report, the eruption of canine into bone-grafted alveolar clefts was recorded as panoramic, occlusal radiographs, in 3 patients grafted with Bio-$Oss^{(R)}$ Results : Like autologous bone graft, the canine was erupted and developed into the cleft alveolar defect through Bio-$Oss^{(R)}$ graft. Conclusion : In some cases that autologous bone graft is not available, we can consider heterogenous bone graft into the cleft alveolar defect for dental development and eruption of impacted teeth.
