    Pattern formation of the ‘Tilapia mark’ in the tilapia fish, Oreochromis mossambicus (1994)

    Notizen: The dorsal fin of the larval and juvenile Oreochromis mossambicus exhibits a unique black spot known as the ‘Tilapia mark’. We traced its development and found that it occupied a specific position in the dorsal fin bounded by rays 15 and 20. Ablation experiments carried out on the larval dorsal fin showed that this spot region constituted a developmental positional field. This positional field in the fin could regenerate and re-establish the spot pattern despite repeated perturbation. The re-establishment of spot was not simply due to fin injury since ablation of the non-spotted region of the dorsal and the tail fin did not result in aggregation of melanophores. We propose that that‘Tilapia mark’ is a result of positional information in operation.

    The use of augmented-pressure colostography in imperforate anus (1997)
    Springer
    Pediatric surgery international 12 (1997), S. 383-385 
    Details

    Notizen: Abstract Colostomy is recommended in most newborns with imperforate anus (IA), except those with low-type anorectal malformations (ARM). Accurate demonstration of the anatomy of any associated fistula between the rectum and the urogenital tract is essential for optimal surgical management. Augmented-pressure distal colostography is recommended to fulfill this requirement prior to definitive surgical repair of IA. We examined 12 cases of high or intermediate-type ARM using this technique, which clearly demonstrated the distal perineal anatomy. All were confirmed at posterior sagittal anorectoplasty.
