  • 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.

  • It is known that low birth weight is a risk factor for poor outcome in cardiac surgery for many cardiac defects. Truncus arteriosus is a rare congenital anomaly that has an unfavorable natural course. We report a successful surgical correction of truncus arteriosus in an 13-day-old premature infant with body weight of 1.5 kg and gestational age of 32 weeks. We used autologous untreated pericardial conduit without valve in right ventricular outflow reconstruction. The patients remains in good condition with normal body weight (50 percentile) and wide right ventricular outflow tract 20 months after the operation.

  • 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.

  • Dry eye syndrome is a relatively common disease of the tears and ocular surfaces that results in discomfort, visual disturbance, and tear film instability with possible damage to the ocular surfaces. Microvascular submandibular gland (SMG) transfer offers a surgical alternative for a permanent autologous substitution of tears using the basal secretion of a transplanted SMG. Long-term follow-up reveals that this technique is a lasting and effective solution for patients with severe dry eye syndrome. The uncomfortable symptoms were relieved, and the frequency of use of pharmaceutical tear substitutes was reduced. Objective examination showed significant improvement in tear film and some features of ocular surface such as breakup time of tear film and corneal staining. Patients may suffer from obstruction of Wharton's duct or epiphora after surgery. Activation of secretion-related receptors could improve the early hypofunction of the denervated SMG and prevent the duct obstruction. Reduction surgery, partial SMG transplantation, uses of atropine gel or Botulinum toxin A could be the choices of treatment for epiphora.

  • Breast reconstruction provides dramatic improvement for patients with severe deformity. The reconstruction not only restores aesthetically acceptable breast for patients with mastectomy deformity but also recovers psychological trauma of 'losing feminity' after the cancer mastectomy. There are many options for breast reconstruction from simple prosthetic insertion to a flap operation using autologous abdominal tissue. The choice of operation method depends on the physical condition of the patient, smoking habits, and economic status. Among the many options, the method that uses the lower abdominal tissue is known as the TRAM (transverse rectus abdonimis myocutaneous) flap. Since the introduction of the TRAM flap in 1982 by Hartrampf, the art of breast reconstruction using lower abdominal tissue has been progressively refined to pedicle flap, muscle-sparinga TRAM flap, and recently there have been exciting and revolutionary changes associated with the adoption of the concept of perforator flap. This refined method of breast reconstruction utilizes lower abdominal tissue nourished by the deep inferior epigastric perforator (DIEP). With the DIEP free flap, almost all of the rectus muscle and anterior rectus sheath are preserved and the donor morbidity is minimized. Different from previous flap methods using lower abdominal tissue, DIEP free flap method preserves function of the rectus muscle completely. 1) Understanding the entire progression of breast reconstruction methods using lower abdominal tissue is necessary for plastic surgeons; the understanding of each step of the exciting progression and the review of the past history of the TRAM flap may provide insight for future development.

  • Lateral epicondylitis, also known as 'tennis elbow', is a degenerative rather than inflammatory tendinopathy, causing chronic recalcitrant pain in elbow joints. Although most patients with lateral epicondylitis resolve spontaneously or with standard conservative management, few refractory lateral epicondylitis are candidates for alternative non-operative and operative modalities. Other than standard conservative treatments including rest, analgesics, non-steroidal anti-inflammatory medications, orthosis and physical therapies, nonoperative treatments encompass interventional therapies include different types of injections, such as corticosteroid, lidocaine, autologous blood, platelet-rich plasma, and botulinum toxin, which are available for both short-term and long-term outcomes in pain resolution and functional improvement. In addition, newly emerging biologic enhancement products such as bone marrow aspirate concentrate and autologous tenocyte injectates are also under clinical use and investigations. Despite all non-operative therapeutic trials, persistent debilitating pain in patients with lateral epicondylitis for more than 6 months are candidates for surgical treatment, which include open, percutaneous, and arthroscopic approaches. This review addresses the current updates on emerging non-operative injection therapies as well as arthroscopic intervention in lateral epicondylitis.
