Caenorhabditis elegans him-6 mutants, which show a high incidence of males and partial embryonic lethality, are defective in the orthologue of human Bloom's syndrome protein (BLM). When strain him-6(e1104) containing a missense him-6 mutation was irradiated with ${\gamma}$-rays during germ cell development or embryogenesis, embryonic lethality was higher than in the wild type, suggesting a critical function of the wild type gene in mitotic and pachytene stage germ cells as well as in early embryos. Even in the absence of ${\gamma}$-irradiation, apoptosis was elevated in the germ cells of the him-6 strain and this increase was dependent on a functional p53 homologue (CEP-1), suggesting that spontaneous DNA damage accumulates due to him-6 deficiency. However, induction of germline apoptosis by ionizing radiation was not significantly affected by the deficiency, indicating that HIM-6 has no role in the induction of apoptosis by exogenous DNA damage. We conclude that the C. elegans BLM orthologue is involved in DNA repair in promeiotic cells undergoing homologous recombination, as well as in actively dividing germline and somatic cells.

Vertigo is one of the subjective symptoms which appears commonly in so many diseases that it is often neglected. But it needs active medical care because it can be a forewarning of serious illness like cerebral apoplexy. This thesis makes a study of vertigo in view of Hyungsang medicine. The followings are the conclusion drawn in diagnosis and treatment of Vertigo: Excess in the upper and deficiency in the lower part(上實下虛) is a main cause of male vertigo. Deficiency in the upper and excess in the lower part(下虛上實) is a general cause of female vertigo. Vertigo is also caused by the insufficiency of the kidney water(腎水) or reservoir of marrow(髓海). persons of Jung pe(精科) with large check bones , those of Fish type(魚類) with Dig mouth and thick lips ; and those with large heads are mainly attacked by this cause. A fleshy person's vertigo comes from the deficiency of Ki and damp phlegm(氣虛濕症) so it is cured by reinforcing Ki, removing dampness and dispelling phlegm. A slim person's vertigo comes from the deficiency of blood and dryness heat(血虛有火) so it is treated by tonifying the blood, cleaning heat away the heat. In case of womanly shaped male and manly shaped female, the vertigo is due to the phlegm fire. Wind-heat(風熱) can cause vertigo generally 施 the persons of following types : wind type(風人), running animal type(走類),bird type(烏類), and Yangmyung meridian type (陽明形). Vertigo also comes from consumption. The deficiency of Ki can be a cause of vertigo in case of male; persons with pale complexion; and those with pronounced noses. The deficiency of blood can be a reason of vertigo in the persons of Hyul type(血科) and those with pale eyelids and lips. The hypofunction of the splean and stomach brings on the deficiency of Ki and blood, which can give rise to the vertigo for those with large nose and mouth. The old people's vertigo comes from the hypofunction of Ki, blood, Yin and Yang.

Objective : Hyperhidrosis is a condition characterized by excessive sweating. Some studies suggest that hyperhidrosis is associated with autonomic nervous system dysfunction. Hyperhidrosis is often accompanied by hypersensitivity, tension, irritability, heat flashes, fatigue, etc. This study was designed to evaluate the correlation between Oriental Medicine diagnosis and the autonomic nervous system function in patients with hyperhidrosis using Heart Rate Variability (HRV) analysis. Methods : 23 palmar and plantar hyperhidrosis patients and 10 systemic hyperhidrosis patients were recruited and evaluated by Oriental Medicine diagnostic questionnaire and HRV analysis. The Oriental Medicine diagnostic questionnaire used a three-dimensional diagnosis that classified patients into Cold or Heat Syndrome, Yin or Yang Syndrome, and Deficiency or Excess Syndrome. Measured indices of HRV used the frequency domain analysis(i.e. TP, VLF, LF, HF and LF/HF ratio). Also, measure indices of HRV adjusted for aging effects were evaluated. Results : Cold/Heat Syndrome was not associated with hyperhidrosis prevalence nor the HRV analysis in hyperhidrosis patients. The Yang Syndrome group(78.8%) was more strongly correlated than the Yin Syndrome group(21.2%), and character of Yang was correlated with the adjusted TP and adjusted LF. The LF/HF ratio in the Excess Syndrome group was significantly higher than the LF/HF ratio in the Deficiency Syndrome group. Conclusion : Hyperhidrosis was not associated with the Cold/Heat Syndrome, but was found to be closely associated with the Yang Syndrome. The LF/HF ratio was significantly higher in the Excess Syndrome group than in the Deficiency Syndrome group in hyperhidrosis patients.

Objectives: Medically unexplained fatigue includes chronic fatigue syndrome (CFS) and idiopathic chronic fatigue (ICF). These disorders quite impair quality of life while no effective therapies exist. Therefore, patients with CFS or ICF frequently choose treatments based on traditional Korean medicine. The study aimed to analyze characteristic of patients visiting an Oriental clinic with CFS or ICF. Methods: Patients who met criteria for CFS or ICF were enrolled in this study, from March 2011 to Jun 2013. Clinical information focused on symptom differentiation and Sasang constitution was analyzed. Pearson's chi-square test was used to compare the frequency among sub-groups. Results: In total, 77 patients (49 male and 28 female) were diagnosed with CFS (17 male and 13 female) or ICF (32 male and 15 female). The symptom differentiation was 37.7%, 26.0%, 13.0%, and 23.3% for "Qi deficiency of both spleen and lung (脾肺氣虛)", "Yin deficiency of both liver and kidney (肝腎陰虛)", "Blood deficiency of both heart and spleen (心脾血虛)" and "Yang deficiency of both spleen and kidney (脾腎陽虛)", while Sasang constitutional distribution was 59.7%, 22.1% and 18.2% Soeumin, Taeumin and Soyangin, respectively. The fatigue severity was notably different between CFS ($63.7{\pm}12.1$) or ICF ($52.2{\pm}15.3$) according to the Chalder fatigue scale (10-point scale for eleven questions). There was statistical significance regarding symptom differentiation and Sasang constitution (p < 0.05). Conclusions: In the process of traditional Korean medicine-based development of therapeutics for patients with chronic fatigue or related conditions, this report can serve as reference data.

The dependence of electronic properties and local structure of tantalum oxide thin film on oxygen deficiency have been investigated by means of X-ray photoelectron spectroscopy (XPS), Reflection Electron Energy Loss Spectroscopy (REELS), and X-ray absorption spectroscopy (XAS). The XPS results showed that the oxygen flow rate change results in the appearance of features in the Ta 4f at the binding energies of 23.2 eV, 24.4 eV, 25.8, and 27.3 eV whose peaks are attributed to Ta1+, Ta2+, Ta3+, Ta4+, and Ta5+, respectively. The presence of nonstoichiometric state from tantalum oxide (TaOx) thin films could be generated by the oxygen vacancies. The REELS spectra suggested the decrease of band gap for tantalum oxide thin films with increasing oxygen deficiency. In addition, XAS spectra manifested both the increase of coordination number of the first Ta-O shell and a considerable reduction of the Ta-O bond distance with the decrease of oxygen deficiency.

It is well established that zinc plays an important role in bone metabolism and mineralization. The role of zinc in bone formation is well documented in animal models, but not much reported in cell models. In the present study, we evaluated zinc deficiency effects on osteoblastic cell proliferation, alkaline phosphatase activity and expression, and extracellular matrix bone nodule formation and bone-related gene expression in osteoblastic MC3T3-E1 cells. To deplete cellular zinc, chelexed-FBS and interpermeable zinc chelator TPEN were used. MC3T3-E1 cells were cultured in zinc concentration-dependent (0-15 ${\mu}M\;ZnCl_2$) and time-dependent (0-20 days) manners. MC3T3-E1 cell proliferation by MTT assay was increased as medium zinc level increased (p<0.05). Cellular Ca level and alkaline phosphatase activity were increased as medium zinc level increased (p<0.05). Alkaline phosphatase expression, a marker of commitment to the osteoblast lineage, measured by alkaline phosphatase staining was increased as medium zinc level increased. Extracellular calcium deposits measured by von Kossa staining for nodule formation also appeared higher in Zn+(15 ${\mu}M\;ZnCl_2$) than in Zn-(0 ${\mu}M\;ZnCl_2$). Bone formation marker genes, alkaline phosphatase and osteocalcin, were also expressed higher in Zn+ than in Zn-. The current work supports the beneficial effect of zinc on bone mineralization and bone-related gene expression. The results also promote further study as to the molecular mechanism of zinc deficiency for bone formation and thus facilitate to design preventive strategies for zinc-deficient bone diseases.

Cardiovascular beriberi is caused by thiamine deficiency and usually presents as high cardiac output failure associated with predominantly right-sided heart failure and rapid recovery after treatment with thiamine. Because of its rarity in developed countries, the diagnosis can often be delayed and missed. We recently experienced a case of cardiovascular beriberi with pulmonary hypertension which successfully treated with thiamine infusion. A 50-year-old man with chronic heavy alcoholics was refered to our department for dyspnea with mental change. Echocardiography showed marked right ventricular (RV) dilatation and flattening of the interventricular septum with a D-shaped deformation of the left ventricle. Moderate tricuspid valve regurgitation was found and estimated RV systolic pressure was 52 mm Hg. Because of his confused mentality and history of chronic alcohol intake, neurological disorder due to thiamine deficiency was suspected and intravenous thiamine was administered and he continuously received a daily dose of 100 mg of thiamine. Follow up echocardiography showed marked reduction of RV dilatation and improvement of a D-shaped deformation of the left ventricle. He finally diagnosed as cardiovascular beriberi on the basis of dramatic response to intravenous thiamine. Thiamine deficiency can cause reversible pulmonary hypertension, and can still be encountered in the clinical setting. Thus high index of suspicion is critically needed for diagnosis.
