  • 신경모세포종은 소아에서 발생하는 흔한 두개외 고형 종양 중 하나로서 진행된 경우 고용량 항암요법 및 자가 말초혈조혈모세포이식 후에도 재발이 잘 되어 예후가 매우 나쁘다. Iodine-131 metaiodobenzylguanidine ($^{131}I-MIBG$)는 치료에 잘 반응하지 않는 신경모세포종 4기 환자를 위한 대증적 치료 요법으로 제한적으로 이용되어 왔다. 저자들은 자가 말초혈조혈모세포이식 후 재발된 신경모세포종 3례에서 $^{131}I-MIBG$를 이용하여 통증을 경감시키고 생존 기간을 늘이는 고식적인 치료 효과를 얻어 이들에 대한 증례 보고를 하는 바이다.

  • Backgroud: Immunotherapy using dendritic cells (DC) loaded with tumor antigens may represent a potentially effective method for inducing antitumor immunity. We evaluated the effectiveness of DC-based antitumor immune response in various conditions. Methods: DC were cultured from peripheral blood mononuclear cells (PBMNC) in myelogenous leukemia (ML) and lysates of autologous leukemic cells are used as tumor antigen. The effectiveness of interleukin-12 (IL-12) and CD40L (CD154) on the antigen presenting function of lysates-loaded DC was analyzed by proliferation, cytokine production, and cytotoxicity tests with activated PBMNC (mainly lymphocytes). For generating antigen-loaded DC, direct fusion of DC with ML was studied. Results: Antigen loaded DC induced significantly effective antitumor immune response against autologous leukemic cells. Administration of IL-12 on the DC based antitumor immune response showed higher proliferation activity, IFN-$\gamma$ production, and cytotoxic activity of PBMNC. Also, fused cell has a potent antitumor immune response. Conclusion: We conclude that lysates-loaded DC with IL-12 may be effectively utilized as inducer of antitumor immune reaction in ML and in vivo application with DC-based antitumor immunotherapy or tumor vaccination seems to be feasible.

  • Pure separation of various leukocytes is required for the assessment of their roles in immunological and phisiological function. In this study, pure separation of monocytes from canine peripheral blood was attempted. At first, mononuclear cells (PBMC) were separated by ficoll-hypaque gradient method and then monocytes were recovered from PBMC suspensions in sucrose gradient Sol. (PBMC-Sucrose), autologous plasma (PBMC-Plasma) and autologous serum (PBMC-Serum) incubated at $37^{\circ}C$ for 2 hours. 1. In the separation of PBMC by ficoll-hypaque gradient method in canine blood, higher relative centrifugal force (RCF) was required, as high as more than 1,300xg RCF for 40 minutes, for clear formation of PBMC layer than that in human blood as usually used 400xg RCF for 40 minutes. 2. In monocytes-separation from three PBMC suspensions following PBMC separation, recovery-, purity- and viability-rate of monocytes showed better results in PBMC-Plasma and PBMC-Serum than in PBMC-Sucrose suspension, particulary showing better results from PBMC suspensions performed by centrifugation at 1,500xg RCF for 40 minutes.

  • Autologous fat injection was first described roughly a century ago and has been used in surgery ever since. In addition to its use in many surgical fields, it is also frequently used for both aesthetic and reconstructive purposes in breast surgery. Since the application of fat grafting in breast surgery has steadily increased, studies investigating its reliability have simultaneously become increasingly common. Previous studies have reported that the use of fat grafting in breast surgery is reliable, but some pending questions remain about its routine use. In order to use fat grafts successfully in breast surgery, it is necessary to be familiar with the structure and content of adipose tissue, the efficacy of adipose stem cell-enriched fat grafts, the oncological safety of fat grafts, and the problems that may occur in the radiological follow-up of patients who undergo fat grafting procedures. In this literature review, we aim to discuss the use of fat grafts in breast surgery by investigating these common problems.

  • Background The loss of nasal tip support is caused by many factors and eventually results in the collapse and eventual dropping of the nasal tip. This reduces the nasolabial (NL) angle and negatively affects respiratory functions and one's appearance. Methods The aim of this retrospective study, which was conducted on 52 patients, was to present and popularize a simple and effective method for the reconstruction of a weakened columella by inserting an autologous ear cartilage graft using a sublabial approach. Results Of all the patients, three patients experienced transplant rejection. The period of follow-up observation was one to five years (mean, 27 months). The results were objectively evaluated by measuring the NL angle in standardized photos before and after the procedure at different time intervals over the follow-up period. We observed a significant increase of the NL angle (mean, $20^{\circ}$), and found these results to be durable over the long term. Of the 52 patients included in this study observed patients, three were dissatisfied (due to immediate infection and shifting of the strut), 28 were satisfied, and 21 were very satisfied. Conclusions The surgical method described here is simple and can be learned quickly. It has very good results with few complications, and is our method of choice for complex and serious cases seen in everyday rhinosurgical practice.

  • Multiple osteochondromas (MO) is characterized by the formation of osteochondromas throughout the entire body. Although the evidence regarding its pathogenesis is well understood, no curative treatment for the disorder is available. Patients can be treated symptomatically by surgical removal of painful osteochondromas. Unfortunately, some patients still suffer from severe pain, even after surgery. We report on a case concerning a 48-year-old woman with a history of MO who presented with persistent pain after surgical removal of a symptomatic osteochondroma of the left scapula and multiple symptomatic osteochondromas of the left foot and trochanteric region. Several interventions to reduce the pain did not have any lasting effect. Subsequently, she was treated with autologous fat grafting (AFG). After each session she was pain-free for at least one year and reported only partial recurrence of the pain. This is the first case report describing AFG for the treatment of pain after both surgical removal of an osteochondroma and symptomatic osteochondromas in a patient suffering MO with promising results. The treatment is more effective and clearly continues to remain active longer than injection therapy or pain medication. Future studies are necessary to confirm our results.

  • In order to study the effect of Bee venom(BV) on the subarachnoid hemorrhage animal model, the autologous whole blood was applied to the vicinity of the sprague dawley rat right femoral artery. Following periarterial application of autologous whole blood(PAB) and intraperitoneal injection of BV(1:5,000 nd 1:500), the vasomotor responses to BV(from 1:500,000 to 1:500) were identified and the histological changes, neovascularized blood vessel were observed. We have shown that alterations in vasomotor and histological findings are elicited following application of periarterial blood and i.p. injection of BV(1:5,000 and 1:500) induced heavy vasospasm and neovascularization on the subarachnoid hemorrhage like model form peripheral artery.
