The cavity liners and bases were used to provide a barrier or protective layer between the exposed dentin and final restoration. This buffer layers might act to reduce or even eliminate postoperative sensitivity. Recently, their light-activated derivatives were introduced as new products, Since many of the new products introduced as a cavity liner or a cavity base, the core properties (such as solubility, acid erosion, ion release, strength, radiopacity and biocompatibilities) of those products should be evaluated based on the proper International Standards and Specifications. For preclinical test, several core properties of eleven commercial products (calcium hydroxide, zinc oxide phosphate, zinc oxide eugenol, glass ionomer, and hydroxyapatite) were tested. Solubility, acid erosion, compressive strength and flexural strength, radiopacity, and cytotoxicity were evaluated according to the International Standards (ISO 3107, 4049, 9917-1, and 9917-2). Almost all experimental groups (zinc oxide eugenol, zinc phosphate, and glass ionomer cements) except for calcium hydroxide groups were met the requirements of ISO specifications, As there were no ISO specifications for the dental calcium hydroxide, it was necessary for suggestion for the guideline of calcium hydroxide products to evaluate those products properly. Commercially available products tested in this study showed proper physical and biological properties for clinical applications.

Torsades de pointes (TdP) is a form of polymorphic ventricular tachycardia associated with a prolonged QT interval or increased U wave. It may occur either in the congenital(idiopathic) form or in the aquired form. Although aquired TdP could be found in many clinical settings such as various drugs, bradycardia, or electrolyte imbalance, it is most commonly induced by drugs. The underlying mechanism is though to be the triggered activity arising as a consequence of early afterdepolarization. Phenothiazine has many derivatives that can lead to occur the cardiovascular events including hypo- tension, syncope, tachycardia and various ECG changes. Chloropromazine is a propylamine derivative of phenothiazine. We report a case of TdP occurred after chloropromazine usual dosage.

Subacute necrotizing lymphadenitis(SNL) is first described in 1972 by Kikuchi and Fujimoto independently, which has benign clinical course with characteristic histologic features. The etiology is unknown but clinical and histological features suggest an infectious agent, which has not been identified. The resemblance of lymph node lesions to those of systemic lupus erythematosus has suggested an autoimmune process. We report a case of a 24-year-old woman who presented with cervical lymphadenopathy, fever, cough and pulmonary lesion in chest x-ray. The histopathological features of the lymph nodes showed typical findings consistent with SNL and the chest lesion was diagnosed as pulmonary tuberculosis by positive sputum AFB smear

The main purpose of this study is to identify and evaluate the depressive states for the patients with chronic pulmonary tuberculosis. A questionnaire(Self-rating Depression Scale, SDS) survey was performed toward 57 pulmonary tuberculosis patients with initial treatment who started chemotherapy and 53 pulmonary tuberculosis patients with retreatment, admitted to one tuberculosis-centered hospital and two general hospital. Fifty three healthy persons as control group were investigated with the same questionnaire for comparison. The survey was performed from July to August 1996. The results are as follws : 1. The patients had significantly high scores in the depression than control and the patient with retreatment showed significantly high scores in the depression than the patient with initia1treatment(P<0.01). 2. The depressive levels of the patients were associated with duration of admission and the expectancy of recovery (P<0.05). 3. The percentage of the subjects with 40 or more scores tentatively classifiable as psychologically depressed was 67.1% of the total subjects, 48.4% of the control groups, 75.0% of the patient with initial treatment and 84.1% of the patient with retreatment. Because patient with pulmonary tuberculosis with initial treatment showed higher depression scores than normal persons, and patients with retreatment due to failure of initial treatment showed higher depression scores than initial treatment, it is necessary to give attention to depression of the patients during treatment of pulmonary tuberculosis.
