  • Toxins produced by marine toxigenic algae have garnered growing attention due to their detrimental impacts on marine ecosystem, aquaculture, and human health. Among these, diarrhetic shellfish poisoning (DSP) toxins, such as okadaic acid (OA), are of particular concern. In this study, we report the successful isolation and structural elucidation of three new derivatives of OA from the marine dinoflagellate Prorocentrum lima. These newly identified compounds, OA-2Me-C7, OA-2-Me-C8, and OA-1-Me-C8, were characterized through a comprehensive series of NMR experiments, combined with structural comparisons to the well-known OA. The identification of these derivatives contributes to the expanding knowledge of DSP toxin diversity and provides new insights into the structural variations of these harmful algal toxins.

  • A chromodorid nudibranch species Cadlinella subornatissima Baba, 1996 (Gastropoda: Nudibranchia: Chromodorididae) is newly recorded from Korean water. In this report, detailed external morphology is provided with its colored illustrations. This species is morphologically distinguished from other congeneric species by the following characteristics: the tip of dorsal papillae is pointed with pink pigment; yellow dorsal marking on central dorsum without mantle margin. The Korean chromodorid nudibranchs are composed of 19 species of 10 genera, including Cadlinella subornatissima which is firstly reported in the present study.

  • In this study, Caenanthura engimatica (Kensley and Reid, 1984) is newly reported from Korea along with detailed description and illustrations. This species can be characterized by the following features: cephalon has a rostrum extending as long as anterolateral lobes; pereonites 4-6 have shallow middorsal pits; the mandible palp has 2 articles; article 1 of the mandible palp is twice longer than article 2; and the maxillipedal palp has 1-3 fused and 4-5 fused articles. This is the first report of C. engimatica beyond Arabian Gulf, the type locality, and Indian Ocean. Additionally, we proposed a revised key to known species of the genus Caenathura Kensley, 1978.

  • Myxomas in the orofacial regions are relatively uncommon tumors that occur in two different types: odontogenic myxomas and soft tissue myxomas. Odontogenic myxomas, derived from the mesenchymal cells such as papillae, dental follicles, or periodontal ligament, occur commonly in the maxilla and mandible. However, soft tissue myxomas in the oral cavity are rare and have been previously reported in only about 30 cases of unknown pathogenesis. The aim of this case report is to present a new case of oral soft tissue myxoma in a 37-year-old male patient who presented with a soft, exophytic round mass on the palate.

  • The severe wear of anterior teeth facilitates the loss of anterior guidance, which protects the posterior teeth from wear during excursive movement. The collapse of posterior teeth also results in the loss of normal occlusal plane and the reduction of the vertical dimension. This case report describes 77-year-old female, who had the loss of anterior guidance, the severe wear of dentition, and the reduction of the vertical dimension. Occlusal overlay splint was used after the decision of increasing vertical dimension by anatomical landmark, facial and physiologic measurement. Once the compatibility of the new vertical dimension had been confirmed, interim fixed restoration and the permanent reconstruction was initiated. This case reports that a satisfactory clinical result was achieved by restoring the vertical dimension with an improvement in esthetics and function.

  • Sarcoidosis is an inflammatory disease involving multiple-organs with an unknown cause. The new onset of sarcoidosis associated with therapeutic agents has been observed in 3 clinical settings; tumor necrosis factor antagonists in autoimmune rheumatologic diseases, interferon alpha with or without ribavirin in patients with chronic hepatitis C or melanoma, and antineoplastic agent-associated sarcoidosis in patients with hematologic malignancies. Here, we report a female patient who developed sarcoidosis after capecitabine treatment as an adjuvant chemotherapy for sigmoid colon cancer. To our knowledge, this is the first report of a capecitabine-induced sarcoidosis.

  • Design subjects have become popular in the engineering education. In these subjects, an active learning skill was introduced to students. Students have to decide a theme and the way how to study it and to find answers by themselves. This learning method was developed in the early year courses in the University of Tokushima. The common learning curriculum among whole university adopted this design subjects from 2005 of the school year and eleven more new subjects started. "Roots finding" is one of them and the objectives are to gain abilities of self-study through the research on a particular subject, and make report then presenting them. Self-learning ability, research ability and presentation skills were enhanced through this subject.

  • Background: The aim of this study was to determine the overall effects and the clinical effect of Korean medicine treatment on chronic atypical chest pain. Case Report: A 56-year-old male patient suffering from chronic atypical chest pain was treated with herbal medicine and acupuncture. We used the Baseline Dyspnea Index (BDI), Pittsburgh Sleep Quality Index (PSQI), and a verbal numerical rating score (VNRS) to assess the patient's symptoms. The administration of the new herbal medicine and local acupuncture point stimulation improved the chest pain and dyspnea symptoms. No side effects were observed during the treatment. Conclusions: The study findings suggest that Korean medicine treatments, such as herbal medicine and local acupuncture point stimulation, may be effective as treatments for atypical chest pain and secondary symptoms in patients with coronary artery disease.

  • Since conventional analgesics have showed limited therapertic value in the treatment of painful neuropathy, the new anticonvulsant gabapentin, has been tried and turned out to be effective and safe in the treatment for various forms of neuropathic pain. The basic pathophysiology of neuropathic pains is abnormal neuronal hyperactivity similar to epileptic seizures. Therefore, we could expect that neuropathic pain would be suppressed by anticonvulsants which inhibit abnormal excessive neuronal output and nerve conduction. This report include effective pain relief in four cases of neuropathic pain with gabapentin without any significant complications.

  • Objectives: Obstructive sleep apnea (OSA) is prevalent disorder, particularly among the middle-aged. In this study, we report a new approach to improve OSA using oriental medicine and acupuncture. Methods: Three men diagnosed with OSA were enrolled in this study. They took oriental medicine 3 times a day and were given acupuncture twice a week for about 4 months. Results: We analyzed apnea-hypopnea index (AHI), oxygen desaturation index (ODI), average saturation (AS) and lowest saturation (LS) before and after treatment. AHI highly decreased in all patients and ODI also decreased in two of the three patients. Conclusions: These results indicate that oriental medicine and acupuncture therapy was effective in the improvement of OSA. Further study in a larger group with severity grades is recommended.
