    Notizen: Abstract  We present two cases of osteoid osteoma in adolescent boys. The lesions were located in the proximal metaphysis of the right tibia and left femoral diaphysis respectively. Doppler duplex color study demonstrated clearly the highly vascular nidus and its feeding artery in one case and only the feeding artery in the second. We believe these are the first descriptions of osteoid osteomas assessed with Doppler duplex color, which was also used as guidance for the percutaneous localization and biopsy.

    Induction of pollen callus in anther cultures of Feijoa sellowiana Berg. (Myrtaceae) (1993)

    Notizen: Summary Anthers of Feijoa sellowiana Berg. (feijoa) produced pollen callus when cultured in Murashige and Skoog medium containing 2,4-dichlorophenoxyacetic acid and benzyladenine or in nurse cultures. Somatic callus was also formed in large amounts from the connective and from the cut end of the filament. Anthers containing microspores at the stage immediately prior to the first pollen mitosis cultured in the presence of 3% sucrose, presented the highest frequencies of induction. Androgenetic divisions were initiated by the formation of two morphologically equal cells, the so-called B-pathway. Attempts to regenerate pollen plants were unsuccessful but leaf-like structures could be obtained in regeneration media containing combinations of gibberellic acid and benzyladenine.
