  • At here, we investigated the historical background, current stage, and concrete therapies of alternatives in cancer therapy. We obtained the conclusion below. 1. Alternative medicine(AM) is a unothodoxial medical physiology, medical practice or intervension that overcome the side effects, faults, limits of coventional medicine. 2. Recentely, as emerging New-age movement, collapse of Decarte's mecanical cosmology, and emphasis on patient rights, the interest of AM is increased, and foreign & domestic use rates of AM are risen. 3. After coventional medicine in cancer therapies that depends on operations, radiations, and chemotherapy is bounded, Alternatives in cancer therapy are rapidly developed, and the majority of users are often considered satisfactory. 4. Alternatives in cancer therapy are classified six boundaries; Diet and Nutrition, Mind-body Technique, Integrated System, Pharmacologic and Biologic treatments, Immuno Enhanced Therapy, Natural and herbal medicine. 5. Looking at contents of Alternatives in cancer therapy, we get to know most of them are similar to the treatment of oriental medicine in holistic method, therapy, philosophy. If we synthesize the alternative medicine's treatment mentioned above and investigate it with oriental medical viewpoint, that may help us approach the conquest of cancer and improve the rate of cure. 6. It is certain that foreign AM will be imported reversely, and we must prepare for rebuilding of Korean traditional AM systemically, investing for activity positively, making national policy for medical system.

  • In the past few decades, biological drugs and small molecule inhibitors targeting inflammatory cytokines, immune cells, and intracellular kinases have become the standard-of-care to treat autoimmune diseases. Inhibition of TNF, IL-6, IL-17, and IL-23 has revolutionized the treatment of autoimmune diseases, such as rheumatoid arthritis, ankylosing spondylitis, and psoriasis. B cell depletion therapy using anti-CD20 mAbs has shown promising results in patients with neuroinflammatory diseases, and inhibition of B cell survival factors is approved for treatment of systemic lupus erythematosus. Targeting co-stimulatory molecules expressed on Ag-presenting cells and T cells is also expected to have therapeutic potential in autoimmune diseases by modulating T cell function. Recently, small molecule kinase inhibitors targeting the JAK family, which is responsible for signal transduction from multiple receptors, have garnered great interest in the field of autoimmune and hematologic diseases. However, there are still unmet medical needs in terms of therapeutic efficacy and safety profiles. Emerging therapies aim to induce immune tolerance without compromising immune function, using advanced molecular engineering techniques.

  • Nervous system is clinically important, and involved in most disorders directly or indirectly. It could be injury and be a source of symptoms. Injury of central or peripheral nervous system injury may affect that mechanism and interrupt normal function. An understanding of the concepts of axonal transport is important for physical therapist who treat injury of nerves. Three connective tissue layers are the endoneurium, perineurium, epineurium. Each has its own special structural characteristics and functional properties. The blood supply to the nervous system is well equipped in all dynamic and static postures with intrinsic and extrinsic vasculation. After nerve injury, alternations in the ionic compression or pressures within this environment may interfere with blood flow and, consequently conduction and the flow of axoplasm. The cytoskeleton are not static. On the contrary, elements of the cytoskeleton are dynamically regulated and are very likely in continual motion. It permits neural mobility. There are different axonal transport systems within a single axon, of which two main flows have been identified : First, anterograde transport system, Secondly, retrograde transport system. The nervous system adapts lengthening in two basic ways. The one is that the development of tension or increased pressure within the tissues, increased intradural pressure. The other is movements that are gross movement and movement occurring intraneurally between the connective tissues and the neural tissues. In this article, we emphasize the biologic aspects of nervous system that influenced by therapeutic approaches. Although identified scientific information in basic science is utilized at clinic, we would attain the more therapeutic effects and develop the physical therapy science.

  • The term "phonosurgery," coined in the early 1960s, refers to surgical procedures that maintain, restore, or enhance the human voice. Phonosurgery includes phonomicrosurgery (endoscopic microsurgery of the vocal folds), laryngoplastic phonosurgery (open-neck surgery that restructures the cartilaginous framework of the larynx and the soft tissues), laryngeal injection (injection of medications as well as synthetic and organic biologic substances), and reinnervation of the larynx. Phonomicrosurgery is a means of maximally preserving the layered microstructure of the vocal fold, that is, the epithelium and lamina propria. The purpose of the surgery is usually to improve the vibratory characteristics of the layered microstructure of the vocal folds. Phonomicrosurgery has developed from convergence of microlaryngoscopic surgical technique theory and the mucosal wave theory of laryngeal sound production. Improvements in technology (i.e., laryngoscopes, handled instruments, and lasers), which in part arise from developments in more frequently performed minimally invasive surgical procedures, will probably facilitate the next generation of procedural innovations. The best methods of optimizing phonosurgical outcomes include making an accurate diagnosis, completing a comprehensive voice evaluation, providing sufficient preoperative therapy, carefully selecting patients to undergo phonomicrosurgical procedures, and requiring sufficient postoperative rest and therapy. Phonomicrosurgery will continue to evolve as a result of the interdependent collaboration of surgeons with voice scientists, speech pathologist, and other voice professionals.

  • Obstructive sleep apnea syndrome is associated with significant cardiovascular morbidity and increased mortality. However, it was controversial whether obstructive sleep apnea syndrome could cause pulmonary hypertension. The controversy was resolved by several studies that have shown pulmonary hypertension in 20% to 40% of patients with obstructive sleep apnea syndrome without underlying other cardiopulmonary diseases and reductions in pulmonary arterial pressure in patients with obstructive sleep apnea syndrome after treatment with nocturnal continuous positive airway pressure. Recent studies provide strong evidence for endothelial dysfunction in obstructive sleep apnea syndrome and pulmonary hypertension. Endothelin-1 is a 21 amino acid peptide with diverse biologic activity such as highly potent vasoconstrictor and mitogen regulator that may play a key role in obstructive sleep ap-nea syndrome and pulmonary hypertension. Continuous positive airway pressure therapy is moderately effective in reducing pulmonary arterial pressure. Further researches are needed to assess the therapeutic efficacy of pharmacologic therapy with agents that inhibit the action of endothelin-1 in obstructive sleep apnea syndrome patients with pulmonary hypertension.

  • The term "endo-perio" lesion has been proposed to describe the destructive lesion resulting from inflammatory products found in varying degrees in both the periodontium and the pulpal tissues. In most of the cases, clinical symptoms disappear following successful endodontic therapy. However failure after conventional root canal treatment calls for surgical intervention. A 35 year old male patient with endo-perio lesion in right maxillary lateral incisor was treated with platelet rich fibrin (PRF) and alloplastic bone substitute after conventional endodontic therapy. At the end of 6 months there was gain in clinical attachment, increased radiographic bone fill and reduction in probing depth which was maintained till 18 month follow-up. Present case report aims to evaluate the efficacy of PRF and alloplastic bone substitute in the management of intrabony defect associated with endo-perio lesion in maxillary lateral incisor because the healing potential of PRF and bone graft has not been widely studied in endodontics. The use of PRF allows the clinician to optimize tissue remodelling, wound healing and angiogenesis by the local delivery of growth factors and proteins. The novel technique described here enables the clinician to be benefited from the full regenerative capacity of this autologous biologic material.

  • Systemic autoimmune diseases arise from loss of self-tolerance and immune homeostasis between effector and regulator functions. There are many therapeutic modalities for autoimmune diseases ranging from conventional disease-modifying anti-rheumatic drugs and immunosuppressants exerting nonspecific immune suppression to targeted agents including biologic agents and small molecule inhibitors aiming at specific cytokines and intracellular signal pathways. However, such current therapeutic strategies can rarely induce recovery of immune tolerance in autoimmune disease patients. To overcome limitations of conventional treatment modalities, novel approaches using specific cell populations with immune-regulatory properties have been attempted to attenuate autoimmunity. Recently progressed biotechnologies enable sufficient in vitro expansion and proper manipulation of such 'tolerogenic' cell populations to be considered for clinical application. We introduce 3 representative cell types with immunosuppressive features, including mesenchymal stromal cells, Tregs, and myeloid-derived suppressor cells. Their cellular definitions, characteristics, mechanisms of immune regulation, and recent data about preclinical and clinical studies in systemic autoimmune diseases are reviewed here. Challenges and limitations of each cell therapy are also addressed.

  • Acinic cell carcinoma is a slow-growing solid neoplasm of salivary gland. Although their cytological and histological finding is bland-looking, their biological behavior is unpredictable. We experienced two cases of acinic cell carcinoma of the salivary gland diagnosed by fine needle aspiration biopsy and confirmed by tissue examination. They showed different clinical courses. We compared their cytologic and histologic findings. The first case was a right preauricular mass in a 58 year-old female of 3 years duration. The cytologic smear revealed sheets or small clusters of monotonous cells mimicking normal serous acinar cells with little cellular pleomorphism. She underwent superficial parotid lobectomy. The tumor was a well demarcated 1.5cm sized nodular mass without infiltration into surrounding parenchyme. The second case was a left submandibular mass in a 23 year-old male of 4 years duration. The smear showed more severe pleomorphism of the tumor cells than those of previous case. Excisional biopsy was done. The excised tumor was $5.5{\times}3.5{\times}3cm$ sized multilobulated solid mass with invasion into surrounding parenchyme. The tumor recurred after 20months, thus total excision of the mass and modified radical neck dissection was carried out. From the above findings, cytologic atypism, infiltrative growth pattern and type of initial therapy may be correlated with biologic behavior.

  • Since discovery of X-rays, radiotherapy has evolved into one of the most scientific branches of medicine and has established its role as the primary line or the secondary line of attack, after surgery, in the treatment of malignant cancers. Nowadays its importance is illustrated by the fact that as many as 70 per cent of all pastients with cancer will receive radiation therapy at sometime during their disease process. Biologic effects of X-rays began to be apparant soon after the discovery by Roentgen in 1895. In clinical radiotherapy, the biologic endpoint of most importance is loss of cellular reproductive ability or clonogenicity. One of the commonest ways to assess cell survival is to use an in vitro plating assay. We analyzed radiation effect on colony formation of HaLa.S3(SC) cell line and obtained results are as follows: The plating efficiency is 0.464. The shape of cell survival curve is similar to multi-target plus single hit component model. Estimated values of Do, Dq, and extrapolation number are 150 cGy, 80 cGy and 1.7 respectively. We reported these experimental data with review of literature.

  • Primary squamous cell carcinoma occuring in the salivary glands involves a grave prognosis since the tumor exhibit infiltrative properties, metastasizes early and recurs readily. But it is so rare that the clinician may see only a few in a lifetime of practice. The following report describes a case of primary squamous cell carcinoma arising from the submaxillary gland treated by combined therapy including surgery, radiotherapy and hyperthermia. The biologic behavior of the tumor was quite abnormal that immediate recurrence was noticed in two weeks after surgery. The progress was dismal and the disease became overwhelming before long.
