PURPOSE To assess, in vitro, the effects of aging and surface polishing on mercury release from dental amalgams exposed to 10% carbamide peroxide at two pH levels. METHODS Samples of fresh and aged amalgam, polished and unpolished, were treated with 10% carbamide peroxide at pH 4.5 and at pH 6.5 for periods of 1, 4, 7, 10 and 13 days. At each time period,(More)
The roots of Onosma argentatum are used traditionally in Turkey for wound healing and burns. The n-hexane-dichloromethane extract of the roots, and four shikonin derivatives (deoxyshikonin, acetyl shikonin, 3-hydroxy-isovaleryl shikonin and 5,8-O-dimethyl acetyl shikonin) isolated from the n-hexane-dichloromethane extract were investigated for their ability(More)
Murine CD4+ Th1 clones require de novo synthesis of proteins to express a cytotoxicity that is mediated by de novo synthesized Fas ligand (FasL). The cytotoxic process of the CD4+ Th1 effectors can be separated into four stages, namely conjugate formation, activation, lethal hit, and effector-independent target cell death. The present study describes the(More)
PURPOSE To examine the effect of toothbrushing with different brands of regular (Meridol, Colgate) and whitening toothpaste (Pearl Weiss, Rembrant, Email Diamant) on bacterial adhesion onto enamel surfaces in vitro. MATERIALS AND METHODS Extracted intact human teeth were brushed twice a day, for 3 minutes with the tested toothpaste for a period of 7 days.(More)
BACKGROUND Chlorpyrifos (CPF), insecticide widely used in agriculture, may cause poisonings in the case of humans. As a result, there is a large amount of treatment research underway to focus on the possibility of chlorpyrifos induced poisonings. The aim of this study has been to evaluate the effects of caffeic acid phenethyl ester (CAPE) and intralipid(More)
Chronic lymphocytic leukaemia (CLL) is a most common form of adult leukemia. No specific marker for CLL has been defined until today. We attempt to produce a specific monoclonal antibody (mAb) to CLL B cells. For this purpose, Balb-C mice were immunised with peripheral blood lymphocytes of a patient with CLL. After the fusion, the immunised mouse spleen(More)
