    Giant cell tumor of bone in a child (1999)

    Notes: Abstract Giant cell tumor (GCT) of bone was first established as a distinct clinicopathological radiographic entity in 1940 when Jaffe distinguished it from other lesions containing giant cells. GCT is rare in patients under 15 years of age. We report a case of GCT in a 10-year-old boy whose X-ray films showed osteolysis suggesting a malignant bone tumor. We believe this to be the youngest patient with giant cell bone tumor ever reported in the Japanese literature.

    Notes: Abstract 6-Acetoxy-5-hexadecanolide (Ia) in the oviposition attractant pheromone released from egg apical droplets of the mosquitoCulex pipiens fatigans Wied. is shown to be the (−)-(5R,6S)- enantiomer. Identification was by chromatography of the 6-trifluoroacetoxy derivatives of the natural pheromone and of the synthetic (−)-(5R,6S)- (Ib) and (+)-(5S,6R)- (IIb) enantiomers on a capillary column having a chiral stationary phase comprising a derivative of (1S,3S)-chrysanthemic acid. The synthetic (−)-(5R,6S)- enantiomer (Ia) attracted oviposition of four fold more mosquito egg rafts than the control (P 〈 0.01) whereas for the (5S,6R)- enantiomer (IIa) there was no statistically significant oviposition attraction.
