  • Radiation-induced fibrosarcoma tumors were grown on the flanks of C3H mice. The mice were divided intro two groups. One group was injected with Photofrin II, intravenously (2.5mg/kg body weights). The other group received no Photofrin E Mice from both groups were irradiated for approximately 15 minutes at 100,300, or $500{\;}mW/\textrm{cm}^2$ with the argon (488nm/514.5 nm), dye(628nm) and gold vapor (pulsed 628 nm) laser light. A photosensitizer behaved as an added absorber. Under our experimental conditions, the presence of Photofrin II increased surface temperature by at least 40% and the temperature rise due to $300{\;}mW/\textrm{cm}^2$ irradiation exceeded values for hyperthermia. Lights and temperature distributions with depth were estimated by a computer model. The model demonstrated the influence of wavelength on the thermal process and proved to be a valuable tool to investigate internal temperature rise.

  • The cytotoxic effect of benzoic acid and related compounds on the growth of normal cell lines and human oral epithelioid cell line was evaluated by the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) and 2,3-bis-[2-methoxy-4-nitro-5-sulfophenyl]-2H-tetrazolium-5-caboxanilide (XTT) methods. 3,4,5-Trihydroxybenzoic acid decreased the cell viability of human oral epithelioid cells and the cell adhesion activity of human oral epithelioid cells. Under the light microscopy, 100 ${\mu}M$ 3,4,5-trihydroxybenzoic acid showed the highest cytotoxic activity. From these results, we can propose that 3,4,5-trihydroxybenzoic acid has a potential anticancer activity.

  • Child obesity has become a significant health issue in Korea. Prevalence of obesity in school-age children in Korea has been alarmingly rising since 2008. Prevalence of obesity among infants and preschool-age children in Korea has doubled since 2008. Obese children may develop serious health complications. Before nutritional counseling is pursued, several points should be initially considered. The points are modifiable risk factors, assessment for child obesity, and principles of treatment. Motivational interviewing and a multidisciplinary team approach are key principles to consider in managing child obesity effectively in the short-term as well as long-term. Nutritional counseling begins with maintaining a daily log of food and drink intake, which could possibly be causing obesity in a child. Several effective tools for nutritional counseling in practice are the Traffic Light Diet plan, MyPlate, Food Balance Wheel, and 'Food Exchange Table'. Detailed nutritional counseling supported by a qualified dietitian is an art of medicine enabling insulin therapy and hypoglycemic agents to effectively manage diabetes mellitus in obese children.

  • Neuroendocrine carcinomas are rare neoplasms of the hypopharynx. Neuroendocrine neoplasms are divided into four main types : carcinoid, atypical carcinoid, small cell carcinoma and paraganglioma. The diagnosis is primarily based on light microscopy and should be confirmed by immunohistochemical investigation. Small cell neuroendocrine carcinoma of the hypopharynx is extremely uncommon tumor and surgical results for this tumor have been disappointing. Chemotherapy and radiotherapy currently appear the most effective forms of therapy. We report our case of small cell neuroendocrine carcinoma of the hypopharynx with the brief review of literatures.

  • Among five sense organs or Gyanendriyas 'Eyes' are considered as most important sense organs. They are said to be the path to mind and seat of Tejas (Light). Now a days due to their overuse and negligence in maintenance we are facing many eye related problems like Dry Eye Syndrome, Cataract, Age related Macular Degeneration, Glaucoma, Computer Vision Syndrome etc. To observe the association of defective lifestyle and related eye problems with their preventive measures, different Ayurvedic procedures are reviewed from ancient literatures and some modern researches. Dinacharya (Daily regimen) explained in Ayurveda helps to prevent many derangements. Lifestyle modification in terms of proper daily regimen and dietary regimen could help to prevent eye problems. Padabhyanga (foot massage) is one of the procedures mentioned in Dinacharya, an effective therapy for healing of eye disorders.

  • Borderline personality disorder (BPD) is characterized by identity and interpersonal problem, affective dysregulation and pervasive severe impulsivity. Although sleep disturbances are not primary symptoms of BPD, they are important aspects of this disorder. However, clinicians and researchers did not give much attention to the sleep symptoms of BPD yet. Measured by nocturnal polysomnography, increased sleep latency as well as reduced total sleep time and sleep efficiency, and 'depression-like' REM abnormalities (i.e., reduced REM latency and increased REM density) are found in BPD patients. Co-morbid sleep disorders such as chronic insomnia, nightmare disorder or circadian rhythm sleep disorder associated with BPD have been reported. Clinicians should focus on the sleep complaints of BPD patients, and carefully manage such symptoms with sleep hygiene education, cognitive psychotherapy or light therapy.

  • The autometallographic method was used to demonstrate the localization of mercury deposits in spleen of mouse. The mercury deposits were identified with the light and electron mocroscope. Mice were treated with methylmercuric chloride in the drinking water (demineralized water) for 40 days. Control and mercury treated groups showed no significant differences in mean body weight and spleen weight per one mouse. Mercury grains were appeared in the germinal center of white pulp consist of a preponderancing lymphocytes, not in red pulp and capsule. At the ultrastructural level, mercury deposits were restricted to lysosomes of macrophage and lymphocyte. Specially, volume in lysosomes of the macrophage was increased. These results suggest that mercury localization in lysosomes is associated with the change of immune activity.

  • Systemic lupus erythematosus is a disease of unknown etiology that affects many organ system and is characterized by the presence of multiple autoantibodies that participated in immunology mediated tissue injury. A 36 years-old female patient was admitted to ward due to high fever and erythematous rash on face and hole body. She exhibited itching sense, joint pain, nausea, fatigue, sensitivity to light. The homatologic finding revealed anemia, decrease of lymphocyte, low platelet count, but LE cell, Anti nuclear antibody(ANA) were negative. In the point of Differentiation of Syndrome(辨證), SLE can be thought to be a category of Seasonal febril disease(溫病). This subject diagnosed as Domination of intense evil heat(熱毒熾盛), and was administrated with Chungonpadocyem-gamibang(淸瘟敗毒飮加味方). The clinical and laboratory findings of our patient were improved by herb medication, acupuncture therapy and general supportive measure.

  • An eight-year-old Shih-Tzu dog was referred to Kyungpook National University Veterinary Medical Teaching Hospital because of severe glaucoma and exophthalmos. The symptoms included severe buphthalmos, conjunctival hyperemia, focal dried cornea and discomfort in the affected eye. Although enucleation was considered as a potential intervention measure in light of the severity of symptoms, it was possible to save the globe and relieve symptoms through evisceration, intraocular prosthesis implantation, and lateral canthoplasty. Our experience with this case suggests that symptomatic salvage therapy, rather than enucleation, is an appropriate approach for resolution of exopthalmos and other complications associated with glaucoma surgery.
