Osteolytic lesions are rare in chronic lymphocytic leukaemia (CLL) and thought to result from Richter's transformation or metastatic disease from nonlymphoid malignancies. We report a patient who presented with a large femoral metastatic lesion and hypercalcaemia caused by CLL itself. Complete remission of CLL with resolution of the osteolytic lesion was achieved with rituximab and cyclophosphamide, adriamycin, oncovin and prednisolone [CHOP (R-CHOP)] combination chemotherapy.
AbstractThe kinetics of the oxidation of cyclopentanol, cyclohexanol, 2methylcyclohexanol, and cycloheptanol by hexacyanoferrate(III) ions in mild alkaline medium has been studied in the presence of traces of ruthenium(VI) ≈ 10−7Mat constant ionic strength (0.26M). The results suggest that the oxidation of the studied cyclic alcohols proceeds via the formation of a complex between Ru(VI) and the substrate which slowly decomposes, giving the reduced form of ruthenium which was reoxidized to Ru(VI) in a fast step by alkaline hexacyanoferrate(III) ions. The product study shows the production of the corresponding ketone.
The oxidation of a primary and a secondary alcohol by hexacyanoferrate(III) under mild conditions employing ruthenium(VI) as homogeneous catalyst has been studied. The results obtained suggest that the oxidation of these alcohols proceeds via the formation of complex between ruthenium(VI) and the substrate which slowly decomposes, followed by a fast reaction between the reduced ruthenium species and hexacyanoferrate(III) ion. A product study shows the formation of the corresponding ketone or aliphatic acid.
