  • It is well known that conventional chemotherapy and radiation therapy can result in toxicity to both normal cells and tumor cells, which causes limitations in the application of these therapeutic strategies for cancer control. Novel and effective therapeutic strategies for cancers with no or low toxicity for normal cells are a high priority. Therefore, natural products with anticancer activity have gained more and more attention due to their favorable safety and efficacy profiles. Pre-clinical and clinical studies have demonstrated that several representative natural compounds such as resveratrol, epigallocatechin-3-gallate, curcumin, allicin and ginsenosides have obvious anticancer potential. In this article, we summarize autophagy-associated targeting pathways of such natural products for inducing the death of cancer cells, and discuss the core autophagic pathways involved in cancer treatments. Recent advances in the discovery, evaluation and exploitation of natural compounds as therapeutic agents for cancers will provide references and support in pre-clinical and clinical application of novel natural drugs for the treatment of primary and metastatic tumors in the future.

  • A patient diagnosed as cellulitis by bone scan was taken the therapeutic intervention of Oriental medicine for 35 days. Cellulitis is characterized by acute purulence inflammation deeply diffused throughout epidermal connective tissue to subcutaneous adipose tissue. This patient presented a finding of soft tissue radioactive isotope uptake increase on bone scan of both foot and ankle. Cellulitis belongs to the category of ong(癰) in Oriental medicine. During therapeutic intervention, 3 herbal prescriptions were applied. Yeonkyopedok-san was applied for high fever and severe chilling on acute stage. After the application of Yeonkyopedok-san and Sunbangwhalmyong-eum, clinical symptoms improved with changes of CRP($112{\rightarro}12),\;WBC(13{\rightarro}8.8),\;ESR(65{\rightarro}46$). After the application of Chungpesagan-tang, clinical symptoms improved with changes of $CRP(12{\rightarro}3),\;WBC(8.8{\rightarro}5),\;ESR(46{\rightarro}13$).

  • Despite the fact that pharmacotherapy depressive disorders have proven efficacy, a substantial number of patients are resistant to conventional management. As neuroscientific research about pathophysiology of depression have accumulated, repeated transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) have emerged as an important mechanism-based treatment modality. This overview provides a review of therapeutic application of rTMS and tDCS in patients with depression. The clinical and basic studies of rTMS and tDCS in depression were reviewed and integrated using a literature review and interview with experts. rTMS is a noninvasive procedure of a localized pulsed magnetic field to the surface of the head to cause a depolarization of neurons in the brain cortex. tDCS has a mechanism of modulating cortical excitability in a polarity-specific manner without eliciting action potentials. rTMS and tDCS seem promising for treating depression. Although therapeutic parameters and further technical improvement remain to be systematically investigated, rTMS and tDCS would be a safe and effective intervention to treat depression.

  • Purpose : The purpose of this study was to test the effect of balance training for proprioceptive and vestibular sensory stimulation and therapeutic environment on expression of BDNF after traumatic brain injury in the rat. Subject : Twelve Sprague-Dawley rats were randomly assigned into group I and group II. After traumatic brain injury, group I was housed in standard cage for 7 days. Group II was housed in therapeutic cage after balance training for 7 days. Method : Traumatic brain injury was induced by weight drop model and after operation they were housed in individual standard cages for 24 hours. After 7th day, the rats were sacrificed and cryostat coronal sections were processed individually in goat polyclonal anti-BDNF antibody. The morphologic characteristics and the BDNF expression were investigated in injured hemisphere section from immunohistochemistry using light microscope. Result : Immunohistochemical response of BDNF in lateral nucleus, purkinje cell layer, superior vestibular nucleus and pontine nucleus appeared very higher in group II than in group I Conclusion : The present result revealed that simultaneously application of balance training for proprioceptive and vestibular sensory stimulation input and therapeutic environment in traumatic brain injured rats is enhance expression of BDNF and it is facilitates neural plasticity.

  • Although colonoscopy was originally a diagnostic imaging procedure, it has now expanded to include an increasing range of therapeutic interventions. These procedures require precise maneuvers of instruments, execution of force, efficient transmission of force from the operator to the point of application, and sufficient dexterity in the mobilization of endoscopic surgical instruments. The conventional endoscope is not designed to support technically demanding endoscopic procedures. In case of colonoscopy, the tortuous anatomy of the colon makes inserting, moving, and orientating the endoscope difficult. Exerting excessive pressure can cause looping of the endoscope, pain to the patient, and even perforation of the colon. To mitigate the technical constraints, numerous technically enhanced systems have been developed to enable better control of instruments and precise delivery of force in the execution of surgical tasks such as apposing, grasping, traction, counter-traction, and cutting of tissues. Among the recent developments are highly dexterous robotic master and slave systems, computer-assisted or robotically enhanced conventional endoscopes, and autonomously driven locomotion devices that can effortlessly traverse the colon. Developments in endoscopic instrumentations have overcome technical barriers and opened new horizons for further advancements in therapeutic interventions. This review describes examples of some of these systems in the context of their applications to advanced therapeutic colonoscopy.

  • Inflammation plays an important role in the progression of atherosclerosis and plaque destabilization converting a chronic process into an acute disorder with ensuing thromboembolism. Current therapeutic effective in preventing atherosclerosis and stroke such as statins, ASS and RAS inhibitors my exert part of their effects by modulating inflammatory responses in the vessel walls. As alternative approaches, discovery to find having inhibitory action of MMP activity, COX-2, macrophage infiltration, such as APE1/ref-1 and fusion technology for cell permeable protein may provide a new antiatherosclerotic therapy in the future.

  • A lactic acid bacterial strain resistant to several antibiotics such as oxytetracycline, tylosin, neomycin and sulfathiazole, which have been often used as a therapeutic agent in livestock, was isolated from the porcine gastrointestinal tract. The isolate YB-55 was identified as belonging to the genus Pediococcus with the highest similarity to P. pentosaceus on the basis of its 16S rRNA sequence and biochemical properties. The isolated strain showed viability of over 85% at pH 3.0 and was resistant to bile salt. The strain produced lactic acid of 12.3 g/L by jar fermentation and maintained its viability in the presence of antibiotics at dosage related therapeutic effect, suggesting P. pentosaceus YB-55 may of ffr potential as a probiotics for livestock.

  • Transcutaneous electrical nerve stimulation (TENS) is one of the representative physiotherapical modalities used for the treatment of various musculoskeletal disorders by the application of electrical stimuli. In dental practice, it has long been used in the treatment of acute and chronic orofacial pain conditions including temporomandibular disorders. TENS is the delivery of therapeutic electrical stimuli with a variety of electrical intensity, frequency and duration to stimulate peripheral nerve through surface electrodes with various form and placement. While controversy still remains over the clinical effectiveness and application of TENS, basic understanding of its electrical properties and the expected biological reactions is important to increase the therapeutic effect and decrease the risk of possible side effects. This review, therefore, focuses on basic understanding of TENS including its underlying mechanisms and stimulation parameters.
